Answer: Check explanation

Step-by-step explanation: (3,-5), because that's the point where the two lines intersect.

Y=-2x+1

Y=-3/2x-1/2

Substitute the Y to get -2x+1=-3/2x-1/2

1/2x=3/2

x = 3

Now plug x into first equation: y=-2*3+1=-5

so the intersection point is (3,-5)

At every company meeting, the president speaks for 28 minutes and then takes questions from her employees. Let q represent the number of minutes she spends answering questions and t represent the total number of minutes the meeting lasts.

Answers

Answer:

t = 20 + q in minutes

Step-by-step explanation:

Company meeting = president speech + questions + answers

President speech = 20 minutes

Questions and answers = q minutes

Total time spent = t minutes

Total time spent = President speech + Total time spent

t = 20 + q

The equation that represents the relationship between q and t is

t = 20 + q in minutes

Sam and Taylor own and operate a car wash service. Sam cleans the interior of each car and Taylor cleans the exterior. The time it takes Sam to finish the interior has a mean of 20 minutes with a standard deviation of 6.4 minutes. The time it takes Taylor to finish the exterior has a mean of 18 minutes with a standard deviation of 4.8 minutes. Both of their finishing times are approximately normally distributed.
Suppose we select a car at random, and define the random variable D as the difference between their finishing times. We can assume that their times are independent.
Find the probability that they finish within 10minutes of each other.

Step-by-step explanation:

The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?

Answers

Answer:

72.1 hours

Step-by-step explanation:

Let the number of hours be represented as: x

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.

Convert 2 7/8 pounds to decimal = 2.875pounds

Hence:

252 - 2.875x

Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.

Convert 3 1/3 pounds to decimal = 3.333 pounds

Hence:

285 - 3.333x

How many hours until they have the same amount of fruit left?

This calculated by equating both equation together

252 - 2.875x = 285 - 3.333x

Collect like terms

-2.875x + 3.333x = 285 - 252

0.458x = 33

x = 33 / 0.458

x = 72.052401747 hours

x ≈ 72.1 hours

They would have the same amount of fruit left after 72.1 hours

You need to setup the equation that is being given to you.

Subtract 14 from my number.

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

Answers

Answer:

12.5%

Step-by-step explanation:

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

The formula for Percentage Decrease =

Decrease in price/ Initial price × 100

Decrease in price = $10

Initial price = $80

Hence:

$10/$80 × 100

= 12.5%

Hence, the percentage the price will be decreased by before tax is 12.5%

Write an expression that is equivalent to 3k - 18

Answers

Answer:

3(k-6)

Step-by-step explanation:

I did it on i-Ready and got it right!

A common factor of 3k and 18 that is greater than 1 is 3.

An expression that shows 3k minus 18 is 3(k)-3(6).

An expression that is equivalent to 3k - 18 can be written as follows:

3(k - 6)

Given is an expression 3k-18 we need to an expression that is equivalent to it,

Let's break it down to understand why this expression is equivalent to 3k - 18:

Distributive Property: The expression 3(k - 6) can be expanded using the distributive property, which states that for any real numbers a, b, and c: a(b + c) = ab + ac.

In this case, a is 3, and b is k while c is -6. So we can apply the distributive property as follows: 3(k - 6) = 3k + 3(-6).

Simplification: The term 3(-6) can be simplified to -18, so the expression becomes 3k - 18.

Therefore, the expression 3(k - 6) is equivalent to 3k - 18 because both expressions yield the same result when evaluated for any value of k.
