<span>-2y=3x+7
    y = -3/2 x - 7/2

y = mx + b where m = slope
so in the equation
</span>y = -3/2 x - 7/2
m = slope = -3/2

perpendicular lines, slope is opposite and reciprocal so slope = 2/3

answer 2/3

hope it helps

A pizza is cut into twelve pieces. Describe the steps you would take to find the area of one slice of the pizza.
DanielleElmas [232]
Hey there!

First, you would need to find the area of the circle/pizza . . .

Formula of finding area → pi*r²  (Pi * the radius of the circle/pizza²)
---
Once you have found the area, you would need to divide the result by the number 12 since there is a total of 12 slices in the pizza.
---
This is how you would find the area of one slice of pizza.

Find the total amount of money​ (maturity value) that the borrower will pay back on a loan of ​$1 comma 760 at 13 and one half %
bagirrra123 [75]

Answer:

The borrower will pay back $4,136.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P.

In this question:

Loan amount of 1760, so P = 1760

Interest rate of 13 and one half, so 13.5%. This means that I = 0.135.

10 years, so t = 10

Interest on the Loan:

E = P*I*t = 1760*0.135*10 = 2376

Total amount:

T = E + P = 2376 + 1760 = 4136

The borrower will pay back $4,136.

In 1990, there were 4,500 deaths due to lung diseases in miners aged 20 to 64 years. The expected number of deaths in this occup
DIA [1.3K]

Answer:

2.5

Step-by-step explanation:

We have that the standardized mortality ratio (SMR) is the relationship between the number of deaths observed in a year, that is, those that occurred and the number of expected deaths, that is, those that were predicted.

SMR = observed / expected

therefore if we replace we have:

SMR = 4500/1800

SMR = 2.5

Which means that the standardized mortality ratio (SMR) is 2.5
