Answer:

Step-by-step explanation:

Y= 8.5x

John ran 3 miles in 25.5 minutes

Y= 25.5 because that is how many minutes it took him

x= 3 because that is how many miles he ran

if you plug it in 25.5= 8.5(3)

it is correct because

8.5+8.5= 17 + 8.5= 25.5 minutes

Step-by-step explanation:

The similar triangles are shown in the attached photo.

Triangle ABC is similar to triangle XZY. Therefore,

AB/XZ = BC/ZY = AC/XY

From the dimensions given,

(x-8)/45 = (2x - 8)/24

Cross multiplying,

24(x-8) = 45(2x - 8)

24x - 192 = 90x - 360

Collecting like terms and making the terms containing the variable, x be on the left hand side and the constants be on the right hand side,

24x - 90x = -360+92

-66x = -268

x = 268/66

x = 4.06

x = 4

Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous yea

Varvara68 [4.7K]

Answer: $56,900\left( 0.919\right)^x$

Step-by-step explanation:

Given

Marcos purchased a sailboat for $\$56,900$

Each year the boat will decrease in value by $8.1\%$

After 1 year it is

$\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\$

after another year it becomes

$\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2$

After $x$ years it is

$\Rightarrow 56,900\left( 1-0.081\right)^x$

$\Rightarrow 56,900\left( 0.919\right)^x$

Deion misses 4% of the free throws he attempts in a seaon. how many total free throws did he attempt if he missed 17

Burka [1]

He has thrown 425 free throws if he missed 17

<h3>How to determine the total number of free throws?</h3>

The given parameters are:

Proportion of free throw missed, p = 4%

Number of free throw missed, n = 17

Let the total number of throws be N.

So we have

n = p * N

Substitute the known values in the above equation

17 = 4% * N

Divide both sides by 4%

N = 425

Hence, he has thrown 425 free throws if he missed 17
