cost $215.80 each, and Rob buys 2 suitcases that cost $36.50 each. Which statement is true?
A) Gabrielle and Rob have $ 2,055.40 of the $2 ,560 left because 2,560 − 2( 215.80 ) − 2(36.50 ) is equal to 2,055.4.

B)Gabrielle and Rob have $2,091.90 of the $2,560 left because 2,560−2(215.80)−36.50 is equal to 2,091.9.

C)Gabrielle and Rob have $2,271.20 of the $2,560 left because 2,560−215.80−2(36.50) is equal to 2,271.2.

D)Gabrielle and Rob have $2,307.70 of the $2,560 left because 2,560−215.80−36.50 is equal to 2,307.7.

Answer:

A

Step-by-step explanation:

215.80 + 215.80 = 431.60

36.50 + 36.50  = 73

431.60 + 73 = 504.60

2560 - 504.60 = 2055.40

olga nikolaevna [1]

Answer:

Height of the stone​ face = 66.29 feet

Step-by-step explanation:

Refer the given figure, here we need to find height of the stone​ face,

Height of the stone​ face = CD

CD = AD - AC

In ΔABC we have

             tan31=\frac{AC}{AB}\\\\tan31=\frac{AC}{900}\\\\AC=540.77feet

In ΔABD we have

             tan34=\frac{AD}{AB}\\\\tan34=\frac{AD}{900}\\\\AD=607.06feet

CD = AD - AC = 607.06 - 540.77 = 66.29 feet

Height of the stone​ face = CD = 66.29 feet

I am a rectangle, and my area is 80 square inches. My width is 2 inches shorter than my length. What is my perimeter?
pshichka [43]
Area=l*b=l*(l-2)=80(given)

so, l^2 - 2l =80
   l^2 - 2l - 80=0
   l=10 or -8

l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36

Suppose the linear regression line y=2.1x+130 predicts sales based on the money spent on advertising. If x represents the dollar
slega [8]

Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.

Linear regression represents the relationship between two variables. the value of y depends on the value of x.

x represents the dollars spent in advertising and y represents the company sales in dollars.

We need to find out sales y when $150 spends on advertising.

Plug in 150 for x and find out y

y = 2.1 x + 130

y = 2.1 (150) + 130

y= 445

The company expects $445 in sales
