Find the area of the triangle below.9 cm6 cm2 cm

You have the following equation:

5x - 3y = -45

In order to solve the previous equation for y, you proceed as follow:

5x - 3y = -45 subtract 5x both sides

- 3y = -45 - 5x multiply by -1 both sides

(-1)(-3y) = (-1)(-45 - 5x)

3y = 45 + 5x divide by 3 both sides

y = 45/3 + 5/3 x order the right side

y = 5/3 x + 15

Hence, the solution for y is y = 5/3 x + 15

Solution

Step-by-step explanation:

7.1 × 103 = 7,100

7.1 × 105 = 710,000

Because 7,100 < 710,000 < 71,000,000 then 7.1 × 105 falls between 7.1 × 103 and 71,000,000

650 --- total

650*.68=442

442 students ate green bean casserole

.68 represents the percentage

so for example, if they asked me for 50% of 1000

we need to multiply 1000*0.5

if they asked for 60% we will multiply 1000*0.6

EXPLANATION

Since we have the function:

Graphing this an the transformation into a graph calculator we have:

We can see that the transformated function is translated 2 units to the right, and that It is also translated 4 units down.

Thus, the transformations are the following:

g(x) is the graph of f(x) translated 2 units to the right and 4 units down.

Answer:

C. Neither

Explanation:

The SSS Congruence Rule states that if the three sides of a triangle are equal to the three sides of another triangle, then the two triangles are congruent.

The SAS Congruence Rule states that if the two sides and the included angle of one triangle are equal to the two sides and the included angle of another triangle, then the two triangles are congruent.

Notice that in the given triangles, there are two congruent sides and a non-included angle, since this does not satisfy any of the rules stated above, SSS Congruence rule or SAS Congruence rule, we'll choose "neither" as the correct answer.

The equation in the point slope form for the line perpendicular to y = (1/4)x-7 that passes through the point (-2,-6) is y+6 = -4(x+2)

The given equation of the perpendicular line

y = (1/4)x -7

The equation is in the slope intercept form of the line

y = mx+b

Where m is the slope of the line

By comparing the given equation with the slope intercept form

The slope of  the line m = 1/4

The slope of its perpendicular line = -1/m

= -4

The point slope form is

[tex](y-y_1)=m(x-x_1)[/tex]

The point is given that (-2,-6)

Substitute these values in the equation

(y-(-6) = -4(x-(-2)

y+6 = -4(x+2)

Hence, the equation in the point slope form for the line perpendicular to y = (1/4)x-7 that passes through the point (-2,-6) is y+6 = -4(x+2)

What is Percent?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

If 5% of an adult's daily potassium requirement is provided by each serving of Crunchy Grain cereal, then x servings will offer x times 5%.

Five times as many servings, or p, of potassium are required for an adult's daily requirement.

As a result,

p = 5x can be used to describe the proportion of potassium in an adult's daily allotment.

How do you convert currency to another currency?

Divide your current currency by the exchange rate if you are aware of it.

Assume, for instance, that you want to change 100 USD into EUR and the USD/EUR exchange rate is 0.631. Simply multiply 100 by 0.631 to do this, and the result is 63.10 EUR, which is the amount you will receive.

Given, 2000 Yen = 16 Euros

and, 40 Euros = 3,125 Indian Rupees

Find rate of yen per India rupee

1 Euro = 2000/16

1 Euro = 125 yen

And, 1 Euro = 3125/40

1 Euro =  78.125 India rupee

Now, find 1 yen = ? Indian rupee

we know,  1 Euro = 125 yen and 1 Euro =  78.125 India rupee

put the values of euro in India rupee in 1 Euro = 125 yen, we get

78.125 India rupee  = 125 yen

1 India rupee = 125 / 78.125

1 Indian rupee = 1.6 Yen

Therefore, the rate of yen per Indian rupee is 1.6

Answer:

Σmf = 23347

Σm²f = 1621631

(Σmf)² = 545082409

Explanation:

The symbol Σ means that we need to sum all the products of m and f.

So, Σmf is equal to:

Σmf =76(94) + 37(92) + 27(63) + 98(62) + 62(81)

Σmf = 7144 + 3404 + 1701 + 6076 + 5022

Σmf = 23347

Then, to find Σm²f, we need to find the square of m, so:

Σm²f = (76)²(94) + (37)²(92) + (27)²(63) + (98)²(62) + (62)²(81)

Σm²f = 5776(94) + 1360(92) + 729(63) + 9604(62) + 3844(81)

Σm²f = 542944 + 125948 + 45927 + 595448 + 311364

Σm²f = 1621631

Finally, (Σmf)² is equal to:

(Σmf)² = (23347)²

(Σmf)² = 545082409

Therefore, the answers are:

Σmf = 23347

Σm²f = 1621631

(Σmf)² = 545082409

a)

We need to convert 1.96 x 10^-5 meters. into standard notation.

Now, on the scientific notation, the power of ten shows how many places the decimal point has been moved.

- If the exponent is positive then the decimal point has been moved to the left.

- If the exponent is negative, then the decimal point has been moved to the right.

In this case, the power is negative 5 . So, the decimal point has been moved 5 places to the right.

Hence:

1.96 x 10^-5 = 0.0000196

b)

a. Meters

First, we need to convert kilometers into meters using the rule of three:

If 1k = 1000 meters

Then 12,100k = x

Where x = (12,100k*1000m)/ 1k

x =12000000 meters

We need to convert from standard notation to scientific notation:

12000000.0 = 1.2x10^7 meters

The decimal point has been moved 7 places to the left, so the power of then is positive 7.

b) We need to convert 12,100 kilometers into scientific notation:

12,100 = 12,100.0

Converting into scientific notation

1.21x10^4 kilometers

The decimal point has been moved 4 places to the left. Hence, the power of the is positive 4.

Answer:

x = 100degrees

Explanation:

Using the theorem;

The angle at the vertex is the half of the difference of its intercepted arcs

Angle at the vertex = 15 degrees

angle at the intercepted arcs = 70degrees and x degrees

According to the theorem;

15 = 1/2(x-70)

Cross multiply

15 * 2 = x - 70

30 = x - 70

Add 70 to both sides

30 + 70 = x - 70 + 70

100 = x

Swap

x = 100degrees

Hence the value of x is 100degrees

The most appropriate choice for arithmetic and geometric series will be given by-

P = 0, Q = 4 , R = 8, S = 16 or P = 15, Q = 9, R = 3, S = 1 are the required numbers

What is arithmetic and geometric series?

Arithmetic series are those series whose difference between two consecutive terms are same.

Geometric series are those series whose ratio between two consecutive terms are same.

Here,

P, Q and R forms an Arithmetic sequence

Let P = a - d , Q = a, R = a + d, Where a is the first term of the Arithmetic sequence and d is the common difference of the sequence.

Let S = b

Q, R and S forms a Geometric sequence

[tex]\frac{a + d}{a} = \frac{b}{a +d}[/tex]

[tex](a + d)^2 = ab\\a^2 + d^2 + 2ad = ab\\[/tex] ............... (1)

Now the sum of first and fourth number is 16

a - d + b = 16

b = 16 - a + d

Putting the value of b in (1),

[tex]a^2 + d^2 + 2ad = a(16 - a +d)\\a^2 + d^2 + 2ad = 16a -a^2+ad\\a^2+a^2 + d^2+2ad - ad - 16a = 0\\2a^2 + ad+d^2 -16a = 0[/tex]............ (2)

Sum of second and third number is 12

[tex]a + a + d = 12\\2a +d = 12\\d = 12-2a[/tex]

Putting the value of d in (2)

[tex]2a^2 + a(12 - 2a)+(12 - 2a)^2-16a = 0\\2a^2 + 12a - 2a^2+144-48a+4a^2 - 16a = 0\\4a^2-52a+144=0\\4(a^2-13a+36)=0\\a^2 -13a+36=0\\a^2-9a-4a+36=0\\a(a - 9)-4(a-9)=0\\(a-4)(a-9) = 0\\[/tex]

[tex]a - 4 = 0[/tex] or [tex]a - 9 = 0[/tex]

[tex]a = 4[/tex] or [tex]a = 9[/tex]

When a = 4,

[tex]d = 12 - 2\times 4\\d = 12 - 8\\d = 4[/tex]

[tex]b = 16 - 4+4\\b = 16[/tex]

P = 4 - 4 = 0

Q = 4

R = 4 + 4 = 8

S = 16

When a = 9,

[tex]d = 12 - 2\times 9\\d = 12 - 16\\d = -6[/tex]

[tex]b = 16 - 9-6\\b = 1[/tex]

P = 9 - (-6) = 15

Q = 9

R = 9 + (-6) = 3

S = 1
