Amira is preheating her oven before using it to bake. The initial temperature of the oven is 75° and the temperature will increase at a rate of 20° per minute after being turned on. What is the temperature of the oven 9 minutes after being turned on? What is the temperature of the oven tt minutes after being turned on?

Answer:

212*(2)ⁿ

6784

Step-by-step explanation:

To find the number of two tailed monkey in 2016 we have

212*2

to find in 2017

212*2*2 or 212*2^2

we can write the following equation

212*(2)^n

where n is the number of years

To find the number of monkeys in 2020 we plug in 5 for n

6784

The measure of ∠O is, 115.8°.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

In ΔMNO, m = 150 inches, n = 550 inches and o=630 inches.

Now, We know that;

⇒ cos O = m² + n² - o² / 2mn

Substitute all the values, we get;

⇒ cos O = 150² + 550² - 630² / (2 × 150 × 550)

⇒ cos O = - 0.4357

⇒ ∠ O = 115.8°

Thus, The measure of ∠O = 115.8°

Answer:

f

f(x) =-3/4x +2

Step-by-step explanation:

You have points (0,2) and (-4,5) Soo the slope is 5-2/-4-0 = 3/-4

Then f(x) = mx+b. So f(x) = -3/4x + 2 because the y intercept is (0,2).

Answer:

f(x)= -x+2

Step-by-step explanation:

Looking at the graph gives us this information:

SLOPE

you can see that for every 1 unit over, it goes one unit down.

slope = rise / run which would be -1/1 which is also just -1

INTERCEPT

the y intercept is 2

equations are typically written in y=mx+b form (where m is the slope and b is the intercept)

so we have y = -1x +2

you don't need to write the 1 because -1x is the same as -x

sof(x)= -x+2

Answer:

Step-by-step explanation:

PART A. Graph the linear equation

- Look at the Graph below as an attachment

PART B. Interpret the slope and the y-intercept

- The slope-intercept form in the linear equation is: y=mx+b

Solve

y=mx+b

y=-15x+375

slope=-15

y-intercept=375

Answer:

x = 20

Step-by-step explanation:

4x + 5x = 9x

9x = 180 (supplementary angles add up to 180 degrees)

Divide 180/9 = 20

Answer:

x = 20.

Step-by-step explanation:

Supplementary angles sum to 180, so:

4x + 5x = 180

9x =  180

x = 20.

Answer:

There are 6 cakes.

Each person can eat 1/2 of a cake.

You need to find how many times you can split 6 cakes into 1/2 of a cake.

Obviously, division is the way to go.

6 ÷ 1/2

When dividing by a fraction, you need to turn both parts into fractions.

6/1 ÷ 1/2

Now you skip the first part.

Focus on 1/2

Flip the fraction: 2/1

Now multiply the two fractions together

6/1 *2/1 = 12/1

Therefore 12 people can be at the party.

Answer: 12 people

Step-by-step explanation:

6 total cakes ; everyone eats [tex]\frac{1}{2}[/tex]

6 people would eat 3 cakes because [tex]\frac{1}{2}[/tex] × 6 people = 3 cakes.

However, 12 people would eat 6 cakes because [tex]\frac{1}{2}[/tex] × 12 people = 6 cakes.

Answer:

B.

{(0, 0), (2, 8)}

Step-by-step explanation:

Substitute 4x in for y in the second equation.  

[tex]2x^{2} - 4x = 0\\[/tex]

2x(x - 2) = 0

x = 0    or x - 2 = 0

                     x = 2

Substitute x = 0 and x = 2  in the first equation to get the corresponding values for y

4(0) = y    and 4(2) = y

y = 0     or   y = 8

So, B is the correct answer

Answer:

(x, y) ⇒ (2x, 2y)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

Given that the inner circle has a radius of 1 r and the outer one has a radius of 2 r. To map the inner circle onto the outer circle, the inner circle would need to be enlarged. The scale factor is:

k = outer circle radius / inner circle radius = 2r / 1r = 2

A dilation with a scale factor of 2 would be needed to map the inner circle onto the outer circle.

That is:

(x, y) ⇒ (kx, ky)

The dilation should be (x, y) ⇒ (2x, 2y)

Transformation refers to the point movement that starts from beginning location to the new location. The dilation refers to the increment or decrement of the figure size.

Here,

The scale factor should be calculated by dividing the  outer circle radius from the inner circle radius

[tex]= 2r\div 1r[/tex]

= 2

Therefore, The dilation should be (x, y) ⇒ (2x, 2y)

Answer:

[tex] {2}^{3} \times {4}^{3} \times 9[/tex]

Step-by-step explanation:

Using the division rule when dealing with exponents

[tex] \frac{b {}^{h} }{b {}^{j} } = b {}^{h - j} [/tex]

meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.

so using that we are going to do 2, 4 and 9

[tex] \frac{2 {}^{8} }{ {2}^{5} } = {2}^{8 - 5 = 3 \: \: \: \: \: 2 {}^{3} } [/tex]

[tex] \frac{ {4}^{4} }{ {4}^{1} } = {4}^{4 - 1} \: \: \: {4}^{3} [/tex]

[tex] \frac{9 {}^{9} }{ {9}^{8} } = {9}^{9 - 8} = 9 {}^{1} [/tex]

Combine all the terms and we get

[tex] {2}^{3} \times 4 {}^{3} \times {9}[/tex]
