Which pairs of angles in the figure below are vertical angles?
Check all that apply.

Answers

ANSWER

A. <AKC and <TKI

D. <IKR and <AKP

EXPLANATION

Vertical angles are also called X-angles.

They are angles in the opposite corners of a figure that looks like X.

From the diagram, the options that are vertical angles are:

A. <AKC and <TKI

D. <IKR and <AKP

The correct answers are A and D.

Answer:

A and D.

Step-by-step explanation:

A pair of angles are vertical if both measure the same and both are opposite by a vertex. Then, in the figure we have that

∠AKC and ∠TKI are vertical angles

∠AKP and ∠PKI are not vertical angles (∠PKI measures more than ∠AKP and these angles are not opposite by a vertex).

∠AKT and ∠PKC are not vertical angles (same reason as the second option).

∠IKR and ∠AKP are vertical angles.

How many 1/4 foot pieces can you cut from a 12 foot board

Answers

Answer:

48

Step-by-step explanation:

Here are two methods for finding the answer.

Method A.

In 1 foot, there are 4 1/4-foot pieces.

In 12 feet, there are 12 times as many as in 1 foot.

12 * 4 = 48

Method B.

Divide 12 ft by 1/4 ft.

12/(1/4) = 12 * 4/1 = 12 * 4 = 48

Answer: 48

If it takes Bianca 30 minutes to bake 2 pans of brownies, how many pans of brownies can she bake in 7 hours?

Answers

Answer:

Bianca can make 28 pans of brownies in 7 hours

Step-by-step explanation:

As we know, 1 hour = 60 minutes

so, 1/2 hour = 30 minutes

Bianca takes 1/2 hour to make pans of brownies = 2 pans

Bianca takes 1 hour to make pans of  brownies = 2 / (1/2) pans

Bianca takes 7 hour to make pans of  brownies = 4 * 7 pans

                                                                                = 28 pans

So, Bianca can make 28 pans of brownies in 7 hours.

D. The car traveled 3 miles In 120 hours,

E. The car traveled 120 miles In 40 hours,​

Answers

Answer:

C

Step-by-step explanation:

Final answer:

The equation represents speed as a function of time. The point (3,120) implies that the car with a speed of 40 miles per hour, travelled a total of 120 miles in a time span of 3 hours.

Explanation:

In this scenario, the equation ys = 40x relates the speed of the car (40 miles per hour) to the time travelled (x in hours). The 'y' in the equation represents the distance travelled by the car. So, when interpreting the point (3,120) on the graph for this equation, '3' refers to time (hours) and '120' refers to distance travelled (miles).

Thus, the point (3,120) on the graph signifies that the car travelled 120 miles in 3 hours, so the correct answer is C. The car traveled 120 miles In 3 hours.

The number of people playing a new phone app game triples every month. When the app first launched, 800 people started playing the game right away. There are currently 194,400 people playing the game. Write an equation to represent this situation, and determine the number of months, t, that have passed since the app launched.

Answers

Answer:

[tex]a_t=ar^{t-1}[/tex]

t=6 months

Step-by-step explanation:

We are given that the number of people playing a new phone app game triples every month

When the app first launch , the number of people started playing the  game  right away=800

According to question

The number of peoples are currently playing the game=194,400

We solve by using the formula of  geometric series because we get a geometric series pattern

The number of people playing the game when app game launch=800

The number of people playing game after one month=2400

800,2400,7200,........,194,400

[tex]a_1=800,a_2=2400,a_3=7200,a_t=194,400[/tex]

We are finding common ratio

[tex]\frac{a_2}{a_1}=\frac{2400}{800}=3[/tex]

[tex]\frac{a_3}{a_2}=\frac{7200}{2400}=3[/tex]

Hence, the common ratio is 3 therefor nth term of  G.P

[tex]a_t=ar^{t-1}[/tex]

a=800,r=3,[tex]a_t=194,400[/tex]

Substitute the values then we get

[tex]194,400=800(3)^{t-1}[/tex]

[tex]\frac[194400}{800}=(3)^{t-1}[/tex]

[tex]243=3^{t-1}[/tex]

[tex]3^5=3^{t-1}[/tex]

When base are same on both side then the power are equals

Therefore, t-1=5

t=5+1=6

Hence, when there are 194,400 people currently playing the game then

the number of months ,t=6 that have passed since the app launched.

If m > 0, then the function is increasing

If m < 0, then the function is decreasing

==================================================

Q1.

y = -2x - 1 → m = -2 < 0 and b = -1

decreasing function, y-intercept -1 → (0, -1)

y = x + 5 → m = 1 > 0 and b = 5

The distance (x) of the foot of the ladder to the bottom of the house is:

Applying the Pythagorean theorem:

x² = l² - h²

A shade of green paint is made by mixing yellow paint and blue paint in the ratio 5:2. Mel has 30 litres of yellow paint and 9 litres of blue paint.what is the maximum amount of green paint she can make?

Answers

Answer:

31.5 litres

Step-by-step explanation:

If Mel uses all 30 litres of yellow paint, then:

5 / 2 = 30 / x

5x = 60

x = 12

Mel would need 12 litres of blue paint, but she only has 9 litres.  So the amount of yellow paint she needs is:

5 / 2 = x / 9

2x = 45

x = 22.5

Mel will use 22.5 litres of yellow paint with 9 litres of blue paint to make a total of 31.5 litres of green paint.

She can make a maximum of 28 litres of green paint.

To find the maximum amount of green paint Mel can make with her yellow and blue paint, we must use the ratio of 5:2 (yellow to blue) given for mixing the green paint.

Firstly, calculate the number of batches of green paint that can be made with the available yellow paint:

Mel has 30 litres of yellow paint and needs 5 litres per batch of green paint, so she can make 30 ÷ 5 = 6 batches from the yellow paint.

Next, calculate the number of batches that can be made with the blue paint:

Mel has 9 litres of blue paint and needs 2 litres per batch of green paint, so she can make 9 ÷ 2 = 4.5 batches from the blue paint.

However, since we cannot have half a batch, the maximum number of full batches Mel can produce from the blue paint is 4.

The limiting reactant here is the blue paint since it allows fewer batches to be made. Therefore, Mel can only make 4 full batches of green paint.

To find the total amount of the green paint from the batches:

Combine the ratios, which add up to 7 parts (5 parts yellow and 2 parts blue).

Multiply the number of batches by the sum of the parts: 4 batches × 7 parts per batch = 28 litres of green paint.

Thus, the maximum amount of green paint Mel can make is 28 litres.

Answers

Hello!

The answer is:

The third option,

c) [tex]h(x)=2.25x-22[/tex]

Why?

We are given the functions E(x) and K(x), since they both are function of the same variable, we need to calculate the difference between them.

From the statement we know the functions:

[tex]f(x)=9.75x+62[/tex]

and

[tex]g(x)=7.5x+84[/tex]

So, calculating the difference the functions we have:

[tex]h(x)=f(x)-g(x)[/tex]

[tex]h(x)=(9.75x+62)-(7.5x+84)[/tex]

[tex]h(x)=(9.75x+62)-(7.5x+84)[/tex]

[tex]h(x)=9.75x-7.5x+62-84[/tex]

[tex]h(x)=2.25x-22[/tex]

Hence, the answer is the third option,

c) [tex]h(x)=2.25x-22[/tex]

Have a nice day!

Answer: Option C

[tex]h(x)=2.25x-22[/tex]

Step-by-step explanation:

To find the function h(x) that models the difference between Hector's and Cari's gains, subtract the functions f(x) with g(x)

That is to say:

[tex]h (x) = f (x) -g (x)[/tex]

We know that

[tex]f (x) = 9.75x + 62\\\\g (x) = 7.5x + 84[/tex]

Then we can find the function h(x)

[tex]h(x) = 9.75x + 62 - (7.5x + 84)\\\\h(x) = 9.75x + 62 -7.5x -84[/tex]

[tex]h(x)=2.25x-22[/tex]

If f(x) = –2x+8 and g(x) = Square root of X+7,
what is (fºg)(2)

Answers

Answer:

(fog)(2)=2

Step-by-step explanation:

Given

f(x)= -2x+8

and

g(x)= √(x+7)

For finding (fog)(2), we have to find (fog)(x) first

In order to find (fog)(x) we will put the value of g(x) in f(x) in place of x.

(fog)(x)= -2g(x)+8

Putting the value of g(x)  

(fog)(x)= -2√(x+7)+8

We have to find (fog)(2), so we have to put at the place of x in the composition

(fog)(x)= -2√(2+7)+8

(fog)(x)= -2√9+8

= -2(3)+8

= -6+8

=2

So,

(fog)(2)=2   ..
