We Need To Know How To Convert The Fraction Into Its Decimal Representation On Level Seven Using Step

Answers

Answer 1

We want to convert our fractions in a way the denominators are potencys of 10. Let's start with the first one.

[tex]\frac{32}{40}[/tex]

If we multiply both the numerator and denominator by 25, we're going to have

[tex]\frac{32\times25}{40\times25}=\frac{800}{1000}=0.8[/tex]

Now, with the next fraction

[tex]\frac{12}{48}[/tex]

Dividing both numerator and denominator by 12, we have

[tex]\frac{12}{48}=\frac{1}{4}[/tex]

Again, If we multiply both the numerator and denominator by 25, we're going to have

[tex]\frac{1}{4}=\frac{25}{100}=0.25[/tex]

For the next fraction, it is enough to multiply both numerator and denominator by 4

[tex]\frac{3}{25}=\frac{12}{100}=0.12[/tex]

For the next one, we can again multiply both the numerator and denominator by 25

[tex]\frac{18}{40}=\frac{450}{1000}=0.45[/tex]

What is the image point of (-12, —8) after the transformation R270 oD ?

Answers

Answer

(-12, -8) after R270°.D¼ becomes (-2, 3)

Explanation

The first operation represented by R270° indicates a rotation of 270° counterclockwise about the origin.

When a rotation of 270° counterclockwise about the origin is done on some coordinate, A (x, y), it transforms this coordinates into A' (y, -x). That is, we switch y and x, then add negative sign to x.

Then, the second operation, represents a dilation of the coordinate about the origin by a scale factor of ¼ given.

The coordinates to start with is (-12, -8)

R270° changes A (x, y) into A' (y, -x)

So,

(-12, -8) = (-8, 12)

Then, the second operation dilates the new coordinates obtained after the first operation by ¼

changes A (x, y) into A' (¼x, ¼y)

So,

(-8, 12) = [¼(-8), ¼(12)] = (-2, 3)

Which of the following measurements form a right triangle? Select all that apply.

Answers

We are asked to find which of the measurements form a right triangle.

A right triangle is a triangle that has an angle of 90°, and also we can use the Pythagorean theorem in them.

The Pythagorean theorem tells us that the sum of the two legs of the triangle squared is equal to the hypotenuse squared:

[tex]a^2+b^2=c^2[/tex]

Where a and b are the legs of the triangle and c is the Hypotenuse. Also, in the right triangle, the hypotenuse is the longest side of the triangle.

We will use the Pythagorean theorem formula on all of the options using the first two given measures as a and b, and check that we the third measure as the value of c.

Option A. 7in, 24in, and 25 in.

We define:

[tex]\begin{gathered} a=7 \\ b=24 \end{gathered}[/tex]

And apply the Pythagorean theorem:

[tex]7^2+24^2=c^2[/tex]

And we solve for c. If the result for x is 25, the triangle will be a right triangle, if not, this will not be an answer.

-Solving for c:

[tex]\begin{gathered} 49+576=c^2 \\ 625=c^2 \end{gathered}[/tex]

Taking the square root of both sides we find c:

[tex]\begin{gathered} \sqrt[]{625}=c \\ 25=c \end{gathered}[/tex]

Since we get the third measure as the value of c option A is a right triangle.

Option B. 18ft, 23ft, and 29 ft.

we do the same as did with option A. First, define a and b:

[tex]\begin{gathered} a=18 \\ b=23 \end{gathered}[/tex]

Apply the Pythagorean theorem:

[tex]18^2+23^2=c^2[/tex]

And solve for c:

[tex]\begin{gathered} 324+529=c^2 \\ 853=c^2 \\ \sqrt[]{853}=c \\ 29.2=c \end{gathered}[/tex]

We get 29.2 instead of just 29, thus option B is NOT a right triangle.

Option C. 10in, 24in, and 26 in.

Define a and b:

[tex]\begin{gathered} a=10 \\ b=24 \end{gathered}[/tex]

Apply the Pythagorean theorem:

[tex]10^2+24^2=c^2[/tex]

Solve for c:

[tex]\begin{gathered} 100+576=c^2 \\ 676=c^2 \\ \sqrt[]{676}=c \\ 26=c \end{gathered}[/tex]

We get 26 which is the third measure given, thus, option C is a right triangle.

Option D. 10yd, 15yd, and 20yd.

Define a and b:

[tex]\begin{gathered} a=10 \\ b=15 \end{gathered}[/tex]

Apply the Pythagorean theorem:

[tex]\begin{gathered} 10^2+15^2=c^2 \\ 100+225=c^2 \\ 325=c^2 \\ \sqrt[]{325}=c \\ 18.03=c \end{gathered}[/tex]

We don't get 20yd as the value of c, thus, option D is NOT a right triangle.

Option E. 15mm, 18mm, and 24 mm

Define a and b:

[tex]\begin{gathered} a=15 \\ b=18 \end{gathered}[/tex]

Apply the Pythagorean theorem

[tex]\begin{gathered} 15^2+18^2=c^2 \\ 225+324=c^2 \\ 549=c^2 \\ \sqrt[]{549}=c \\ 23.43=c \end{gathered}[/tex]

We don't get 24 as the value of c, thus, option E is Not a right triangle.

Answer:

Option A and Option C are right triangles.

A 6000-seat theater has tickets for sale at $24 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue
of $168,000?
The number of tickets for sale at $24 should be ?

Answers

The number of tickets which should be sold to $24 and $40 are 4500 and 1500 respectively.

Given, A 6000-seat theater has tickets for sale at $24 and $40.

How many tickets should be sold at each price for a sellout performance to generate a total revenue of $168,000 = ?

first, assign variables:

X = # of $24 tickets,  Y = # or $40 tickets

write equations based on the data presented:

"6000 seat theater..."

   X + Y = 6000 ...equation 1

"total revenue of 168,000"

The revenue from each type of ticket is the cost times the number sold, so:

  24X + 40Y = 168,000 .....equation 2

from equation 1:

   X = 6000 - Y

substitute this into equation 2:   (replace X with 6000-Y)

   24 (6000 - Y) + 40Y = 168,000

expand:

144,000 -24Y + 40Y = 168,000

rearrange and simplify:

    16Y = 168,000 - 144,000

    y = 24000/16

     Y = 1500

from equation 1:

     X = 6000 - 1500

     X = 4500

hence the number of tickets for sale at $24 should be 4500.

Find the probability of drawing a red ace and then a spade when two cards are dranw (without replacement) from a standard deck of cards.a. 1/102b. 31/102c. 1/2d. 31/64

Answers

a. probability of drawing a red ace (first draw)

In a standard deck, there are 52 cards. Out of these 52 cards, two are red aces. Hence, the probability of drawing a red ace is 2/52 or 1/26.

b. probability of drawing a spade (second draw)

On the second draw, 51 cards are left. Assuming that a red ace was taken on the first draw, 13 spades are left on the deck. Hence, the probability of drawing a spade is 13/51.

So, to get the probability of drawing a red ace AND a spade, simply multiply the two probabilities above.

[tex]\frac{1}{26}\times\frac{13}{51}=\frac{13}{1326}[/tex]

Then, reduce 13/1326 into its simplest form by dividing both numerator and denominator by 13.

[tex]\frac{13\div13}{1326\div13}=\frac{1}{102}[/tex]

Hence, the probability of drawing a red ace AND a spade is 1/102. (Option A)

Given circle O with diameter AC, tangent AD, and the measure of arc BC is 74 degrees, find the measures of all other indicated angles.

Answers

We want to find the measure of the angles 1 to 8, given that the diameter is AC and the measure of the Arc BC is 74°.

The angle 5, ∡BOC is central and it is equal to the measure of the arc it intercepts, the arc BC. Thus the angle 5 is 74°.

The angle 4, ∡AOB also is central, and it is equal to the measure of the arc AB. As the line AC is the diameter of the circle O, the arc AC is equal to 180°, and thus, the sum of the angles 4 and 5 will be 180°:

[tex]\begin{gathered} \measuredangle4+\measuredangle5=180^{\circ} \\ \measuredangle4=180^{\circ}-\measuredangle5=180^{\circ}-74^{\circ}=106^{\circ} \end{gathered}[/tex]

Thus, the angle 4 is 106°.

The angle 6 is an inscribed angle, and thus it is half of the arc it intersects, the arc AB. This means that the angle 6 is 106°/2=54°.

The angle 2 also is an inscribed angle, half of the arc BC, and thus, the angle 2 is 74°/2=37°.

Now, the triangle BOC has the angles 5, 6 and 7, and the sum of those angles is 180°. This means that:

[tex]\begin{gathered} \measuredangle5+\measuredangle6+\measuredangle7=180^{\circ} \\ 74^{\circ}+54^{\circ}+\measuredangle7=180^{\circ} \\ 128^{\circ}+\measuredangle7=180^{\circ} \\ \measuredangle7=180^{\circ}-128^{\circ}=52^{\circ} \end{gathered}[/tex]

Thus, the angle 7 is 52°.

Following a same argument, we can get the angle 8, as being part of the triangle AOB.

[tex]\begin{gathered} \measuredangle2+\measuredangle4+\measuredangle8=180^{\circ} \\ \measuredangle8=180^{\circ}-37^{\circ}-106^{\circ}=37^{\circ} \end{gathered}[/tex]

This means that the angle 8 is 37°.

As the line AD is tangent to the circle O, this means that the lines AC and AD are perpendicular, and thus, the angle 1 is 90°.

Lastly, as the angles 1, 2 and 3 are coplanar, their sum is 180°. This is:

[tex]\begin{gathered} \measuredangle1+\measuredangle2+\measuredangle3=180^{\circ} \\ \measuredangle3=180^{\circ}-\measuredangle1-\measuredangle2 \\ \measuredangle3=180^{\circ}-90^{\circ}-37^{\circ}=180^{\circ}-127^{\circ}=53^{\circ} \end{gathered}[/tex]

Thus, the angle 3 is 53°.

The shape of the distribution is bell-shaped. This is because the distribution presents a normal distribution

The distribution is almost symmetrically skewed with no outlier

The center is about 60 inches(about 59 wild bears before the center and about 84 wild bears beyond the center)

The distribution is widely spread: The data range is the highest inches minus the lowest inches

Therefore, the spread of the distribution is 85 inches - 35 inches, which equals 50 inches.

I need help with a 8th-grade math assignment:China has a population of approximately 1,382,323,332 people. The United States has a population of about 324,118,787 people.Part AUsing scientific notation, give the approximation for each population. Round the first factor to the nearest tenth.China: United States: Part BAbout how many more people live in China than in the United States? Express your answer using scientific notation. Round the first factor to the nearest hundredth.

Answers

We have the next given information:

China has a population of approximately 1,382,323,332 people.

The United States has a population of about 324,118,787 people.

a) We need to use scientific notation which is given by the next form:

[tex]ax10^n[/tex]

Where a is the coefficient rounded to the nearest tenth.

and a is the terms moved to the decimal point.

For China:

1382323332.0, we moved the decimal point nine spaces to the right.

then

1.382323332

Expressed in scientific notation and rounded to the nearest tenth:

[tex]1.4x10^9[/tex]

For the United States:

324,118,787 with the decimal point 324,118,787.0

then

324118787.0

Move the decimal point 8 spaces to the right, then:

3.24118787

Expressed in scientific notation and rounded to the nearest tenth:

[tex]3.2x10^8[/tex]

Part b:

To find how many more people live in China than in the United States, we need to subtract between China and the United States:

Then:

1,382,323,332 - 324,118,787 = 1,058,204,545

Now

1,058,204,545 equal to 1058204545.0

We need to move the decimal point 9 spaces:

1.058204545

Expressed as scientific notation and rounded to the nearest hundredth:

[tex]1.06x10^9[/tex]

The factors of a polynomial tell us the points where the graph intersects the x-axis.

From the graph provided in the question, the graph cuts the x-axis at the points:

[tex]x=-4,x=-2,x=1[/tex]

Therefore, the factors will be:

[tex]\begin{gathered} x=-4,x+4=0 \\ x=-2,x+2=0 \\ x=1,x-1=0 \\ \therefore \\ factors\Rightarrow(x+4),(x+2),(x-1) \end{gathered}[/tex]

Therefore, the polynomial will be:

[tex]f(x)=(x+4)(x+2)(x-1)[/tex]

OPTION C is the correct option.
