a 10 miles per hour
b 15 miles per hour
c 30 miles per hour
d 65 miles per hour

Answers

Answer: B) 15 mph

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

Explanation:

The equation d = 65t means that the rate is r = 65. So Malcolm's family travels at an average rate of 65 mph. Note this is the slope of the line.

The graph has a slope of 50 because each time we go up 50, we move to the right 1. Ie, slope = rise/run = 50/1 = 50. You could use the slope formula to get the same result.

Since the graph has a slope of 50, this means Theo's family is going at an average speed of 50 mph.

Subtract the two speeds to get 65-50 = 15 mph

In 1995 the town of Springdale had a population of 2,378. Over the next 20 years the town's population decreased by 12.5%. What was the population of the town in 2015?

Answers

Answer: 165

Step-by-step explanation:

Exponential equation for decay :[tex]A= P(1-r)^t[/tex] , where A is the value after t year, P = initial value.

As per given ,

P= 2378

t= 20 years

r = 12.5% = 0.125

Now ,

[tex]A=2378(1-0.125)^{20}\\\\=2378(0.875)^{20}\\\\= 2378(0.0692087587)\\\\=164.57842\approx 165[/tex]

Hence, the population of the town in 2015 = 165

What are two ways to start solving the equation 4(c - 3)=8? Choose BOTH ways
1. Add 3 to both sides to get 4c = 11

2. Divide both sides by 4 to get c - 3 = 2

3. Use the distributive property to get 4c - 3 = 8

4. Use the distributive property to get 4c - 3 = 8

5. Subtract 4 from both sides to get c - 3 = 4

Answers

Answer

2, i can't find any other solution

Step-by-step explanation:

you divided both sides by 4 you get x - 3 = 2/2 plus 3 = 5 = x

To solve an equation 4(c - 3) = 8 the correct ways are

1. Use the distributive property to get 4c - 12 = 8

2. 2. Divide both sides by 4 to get c - 3 = 2

What is an equation?

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

The two ways to start solving the equation 4(c - 3) = 8 are:

Use the distributive property to get 4c - 12 = 8, then add 12 to both sides to get 4c = 20, and finally divide both sides by 4 to get c = 5.

This method uses the distributive property to simplify the left-hand side of the equation before solving for c.

Divide both sides by 4, and we get,

4(c - 3)/4 = 8/4

c - 3 = 2

c = 5.

Therefore, the two ways are given above.

Kevin bought twelve 8-ounce bottles of water. How many milliliters of water did Kevin buy? (Note: 1 ounce ≈ 30 ml) Thank you for any help I may get! <3

Answers

Given:

Kevin bought twelve 8-ounce bottles of water.

1 ounce ≈ 30 ml

To find:

The quantity of water in milliliters

Solution:

We have,

1 ounce ≈ 30 ml

8 ounce ≈ 8×30 ml

8 ounce ≈ 240 ml

It means, one 8 ounce bottle can hold about 240 milliliters of water.

Total number of bottles = 12

So, the quantity of water Kevin buy in milliliters is

[tex]12\times 240=2880[/tex]

Therefore, Kevin buys 2880 milliliters of water in twelve 8-ounce bottles.

Simplified or expanded version of 8(4x-12)

Answers

Answer: 32x - 96

Step-by-step explanation: If I’m not wrong, that’s the answer. You distribute the 8 to each of the numbers, so you multiply. 8 multiplied by 4x would be 32x. 8 multiplied by 12 is 96. You then put the subtraction sign in. You could also think of it as 8 times -12. That’ll still get you -96. It would be 32 and the negative 96, so it seems like the negative is the subtraction sign.

Answer the question above

Answer:

it is C.

Step-by-step explanation:

In △ACD, if AC≅AD, m∠A = 3x − 4, m∠C = 5x + 1, and m∠D = 7x − 27, find x and the measure of each angle.

Answers

Answer:

x = 14

m∠A = 38°

m∠C = 71°

m∠D = 71°

Step-by-step explanation:

By the property of a triangle,

"Sum of interior angles of a triangle is 180°"

m∠A + m∠C + m∠D = 180°

By substituting the values of the angles given in the question,

(3x - 4)° + (5x + 1)° + (7x - 27)° = 180°

(3x + 5x + 7x) + (-4 + 1 - 27) = 180

15x - 30 = 180

15x = 210

x = 14

Therefore, m∠A = 3x - 4

                           = 3(14) - 4

                           = 38°

m∠C = 5x + 1

        = 5(14) + 1

        = 71°

m∠D = 7x - 27

         = 7(14) - 27

         = 98 - 27

         = 71°
