A seamstress has three colours of ribbon; the red is 126cm, the blue is 196cm and the green
is 378cm long. She wants to cut them up so they are all the same length, with no ribbon
wasted. What is the greatest length, in cm, that she can make the ribbons?

Answers

Answer 1

Answer:

14cm is the greatest length

Step-by-step explanation:

Hi!

So the question is basically asking for the greatest common factor between each of these numbers (if I understood the question right so here we go) :

The GCF in this case is 14:

126 / 14 = 9

196 / 14 = 14

378 / 14 = 27

Please feel free to ask me any more questions that you may have!

and Have a great day! :)

Answers

Answer:

1) 4x + 12

2) new area = 16x + 48

3) Yes, the ratio is the same for positive values of x

Explanation:

The distributive property of multiplication is shown below

a(b + c) = ab + ac

The area of the given rectangle is expressed as

Area = 4(x + 3)

By applying the distributive property, it becomes

4 * x + 4 * 3

= 4x + 12

The equivalent expression is

4x + 12

If the dimensions of the rectangle are doubled, then

new length = 2(x + 3) = 2x + 6

new width = 4 * 2 = 8

Thus,

new area = 8(2x + 6) = 8 * 2x + 8 * 6

new area = 16x + 48

We would input values of x into both areas and find their ratios

For x = 1,

area = 4(1) + 12 = 16

new area = 16(1) + 48 = 64

ratio = 16/64 = 1/4

For x = 2,

area = 4(2) + 12 = 20

new area = 16(2) + 48 = 80

ratio = 20/80 = 1/4

For x = 3,

area = 4(3) + 12 = 24

new area = 16(3) + 48 = 96

ratio = 24/96 = 1/4

Thus, the ratio is the same for positive values of x

Linda's medicine bottlesays "If you will be driving, then youshould not take this medicine." What arethe inverse, converse, and thecontrapositive of this statement?

Answers

For two statements p and q, and the compounded statement "If p, then q", we have the following definitions for the inverse, converse, and contrapositive of this compounded statement:

inverse: If not p, then not q.

converse: If q, then p.

contrapositive: If not q, then not p.

So, for the presented statement, i. e., "If you will be driving, then you should not take this medicine" we have:

p: you will be driving

q: you should not take this medicine

Notice that:

not p: you will not be driving

not q: you may take this medicine

Then, using the above definitions, we write:

inverse: If you will not be driving, then you may take this medicine.

converse: If you should not take this medicine, then you will drive.

contrapositive: If you may take this medicine, then you will not be driving.

The value of the composite function is as follows:

How to find composite function?

The composite function can be solved as follows:

Composite functions are when the output of one function is used as the input of another.

In other words, a composite function is a function that depends on another function.

f(x) = x² - 6x + 2

g(x) = -2x

Therefore,

(gof)(5) =  g(f(5))

So we need to find g(f(x)) first.

Therefore,

g(f(x)) = -2(x² - 6x + 2)

g(f(x)) = - 2x² + 12x - 4

Therefore,

g(f(x)) = - 2x² + 12x - 4

(gof)(5) =  g(f(5)) = - 2(5)² + 12(5) - 4

(gof)(5) =  g(f(5)) = -50 + 60 - 4

(gof)(5) =  g(f(5)) = 6

The path of the baseball follows the equation h= -4.9t^2 + 60t + 1.5 where h represents the height of the baseball, t seconds after the baseball was hit. How long will it take the baseball to return to the ground?

Answers

SOLUTION

Given the question in the question tab, the following are the steps to solve the problem:

Step 1: Write out the equation for the path of the baseball where h is height and t is time in seconds

[tex]h=-4.9t^2+60t+1.5[/tex]

Step 2: Rewrite the new equation

The height of the baseball when it returns to the ground is zero(0). Therefore, at that point where the baseball returns to the ground, the function becomes:

[tex]0=-4.9t^2+60t+1.5[/tex]

Step 3: We solve the quadratic equation to get the value of t:

[tex]\begin{gathered} 0=-4.9t^2+60t+1.5 \\ u\sin g\text{ quadratic formula which states that:} \\ x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \\ a=-4.9,b=60,c=1.5 \\ \text{Substituting the values, we have:} \\ \frac{-60\pm\sqrt[]{60^2-4(-4.9)(1.5)}}{2(-4.9)} \\ =\frac{-60\pm\sqrt[]{3600+29.4}}{-9.8} \\ =\frac{-60\pm60.2445}{-9.8} \\ =\frac{-60+60.2445}{-9.8}\text{ or }\frac{-60-_{}60.2445}{-9.8} \\ =\frac{0.2445}{-9.8}or\frac{-120.2445}{-9.8} \\ t=-0.024948979\text{ or }12.26984184 \\ t\approx-0.0249\text{ or 12.270} \end{gathered}[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x1, y1) and (x2, y2) are points of the line.

Therefore, if we replace (x1, y1) by (5, -4) and (x2, y2) by (-1, 8), we get that the first step is to calculated:

y2 - y1 = 8 - (-4) = 8 + 4 = 12

Answers

In the given equation A, we can (A) subtract the same quantity from both sides.

What are equations?In a mathematical equation, the equals sign is used to express that two expressions are equal. An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values. Like 3x + 5 = 15, for example. There are many different types of equations, including linear, quadratic, cubic, and others. The three primary forms of linear equations are point-slope, standard, and slope-intercept.

So, obtain equation B from equation A:

Equation A: 2x - 1 = 5xEquation B: -1 = 3x

We can subtract (2x) from both sides to get equation B as follows:

2x - 1 = 5x2x - 2x - 1 = 5x - 2x-1 = 3x

Therefore, in the given equation A, we can (A) subtract the same quantity from both sides.

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Get the angles of the hexagon

The internal angles of an hexagon is given as:

[tex]\begin{gathered} \frac{180(n-2)}{n} \\ n=6\text{ since hexagon has 6 sides} \\ So\text{ we have:} \\ \frac{180(6-2)}{6}=\frac{180(4)}{6}=\frac{720}{6}=120\degree \end{gathered}[/tex]

Therefore each angle of the hexagon is 120 degrees.

STEP 2: find the length of the sides

We remove the right triangles as seen below:

Using the special right triangles, we have:

STEP 3: find the area of the extracted triangle above

[tex]\begin{gathered} b=1,h=\sqrt{3} \\ Area=\frac{1}{2}\cdot1\cdot\sqrt{3}=\frac{\sqrt{3}}{2}units^2 \end{gathered}[/tex]

Since there are two right triangles, we multiply the area by 2 to have:

[tex]Area=2\cdot\frac{\sqrt{3}}{2}=\sqrt{3}[/tex]

There are two triangles(both sides), therefore the total area of the shaded area will be:

[tex]\sqrt{3}\cdot2=2\sqrt{3}[/tex]

STEP 4: Find the area of the whole hexagon

[tex]\begin{gathered} Area=\frac{3\sqrt{3}s^2}{2} \\ s=hypotenuse\text{ of the right triangle}=2 \\ Area=\frac{3\sqrt{3}\cdot4}{2}=6\sqrt{3} \end{gathered}[/tex]

STEP 5: Find the probability

[tex]\begin{gathered} Probability=\frac{possible\text{ area}}{Total\text{ area}} \\ \\ Possible\text{ area}=2\sqrt{3} \\ Total\text{ area}=6\sqrt{3} \\ \\ Probability=\frac{2\sqrt{3}}{6\sqrt{3}}=\frac{1}{3}=0.3333 \end{gathered}[/tex]

Hence, the probability that the dart hits one of the shaded areas is approximately 0.3333

Answers

The interest that Harold pay is $768.75 and his maturity value is $17168.75.

Harold Hill borrowed $16,400

Harold must repay the loan at the end of 15 months in one payment with 3 3/4 % of interest

First we need to calculate the interest amount

=  loan amount x rate of interest x number of months

interest = (16400 x 3 3/4 x 15/12)/100

interest = $768.75

The maturity value = loan amount + interest

= 16400 + 768.75

= 17168.75

Therefore, the interest that Harold pay is $768.75 and his maturity value is $17168.75.

Amount the plastic bag can carry = 1/8 pounds

First convert 2⅔ to a simple fraction:

Answer:

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = 63 inches

μ is the population mean = 70 inches

σ is the population standard deviation = 3 inches

For x shorter than 63 inches = x < 63

Z score = x - μ/σ

= 63 - 70/3

= -2.33333

Probability value from Z-Table:

P(x<63) = 0.0098153

Approximately to the nearest thousandth = 0.010

Therefore, the probability that a randomly selected student will be shorter than 63 inches tall, to the nearest thousandth is 0.010.
