A hardware store mixed 7 gallons of red paint with every 11 gallons of blue paint to make purple paint. Which ratio of gallons of red paint to gallons of blue paint will make the same shade of purple paint?

**Answer:**

2 b + 6 r = 2 * 24

5 b + 3 r = 2 * 21 ... 10 b + 6 r = 84

subtracting equations (to eliminate r) ... 8 b = 36

solve for b , then substitute back to find r

When Damian runs the 400 meter dash, his finishing times are normally distributed

with a mean of 60 seconds and a standard deviation of 1 second. Using the empirical

rule, determine the interval of times that represents the middle 99.7% of his finishing

times in the 400 meter race.

The **middle 99.7%** is within **60 seconds to 63 seconds.**

The **empirical rule **states that for a normal distribution, **68%** are within **one standard deviation** from the **mean, 95%** are within **two standard deviations **from the** mean** and** 99.7%** are within** three standard deviations **from the **mean**.

Given that:

mean (μ) = 60 seconds, standard deviation (σ) = 1 second

**99.7%** are within three standard deviations = μ ± 3σ = 60 ± 3(1) = **(57, 63)**

The **middle 99.7%** is within **60 seconds to 63 seconds.**

A motorboat moves across a lake at a constant speed. When it begins, it is 28

km from the shore. After 12 minutes, it is 4 km from the shore. Which

function describes the motorboat's distance from the shore?

O A. y=-12x+28

B. y=-2x + 28

c. y = 2x+28

D. y = 12x + 28

Answer: B. y= -2x+28

Steps:

In the equation, take,"y" as result of the distance of the motorboat from the shore.

Now take the "x" value as the time taken. And hold the unit of x as 12 because you already know that in 12 minutes the motorboat is 4km far from the shore. Then solve the four equations and find out which ones value of,"y" comes 4

After doing all the equations i m pretty sure you will that B. y= -2x + 28

y= -2 * 12 + 28

y= -24+28

y= 4

The answer is B

Answer: 1260 books

Step-by-step explanation:

2/5=0.4

19000x0.4=7600

12500x0.4=5000

7600+5000=12600

1/10=0.1

12600x0.1 = 1260

/**Answer:**

1,260 books (or C)

**Step-by-step explanation:**

1. 2/5 of fiction (12,500) are out, so 5,000 are out

2. 2/5 of non-fiction (19,000) are out, so 7,600 are out

3. Total books checked out are 12,600

4. 1/10 of checked out books are due this week, so 1,260 books (10%)

The value of a newly purchased computer will decrease over time. The value of the computer can be modeled by the following function:

f(t)=200+1,200(0.73)2t,

where t is measured in years since the computer was purchased.

Use the drop-down menus to complete the explanation of how the function models the computer's value over time.

**Answer:**

**Step-by-step explanation:**

Substitute 0 for t and evaluate the expression. Recognize that any value to the zero power is 1.

f(0) = 200 +1200(0.73^(2·0)) = 200 +1200·1

f(0) = 1400

**When t=0, the value of the computer is 1400 dollars**.

__

b)The exponential expression 1200(0.73^(2t)) has a horizontal asymptote of 0. **It gets closer and closer to 0**.

__

c)The exponential term gets closer to 0, so the function value gets closer to ...

f(∞) ≈ 200 +0 ≈ 200

**f(t) gets closer and closer to 200**.

Answer:

1) 1,400

2) 0

3) 200
