Answers

Answer 1

Answer:

Answer:

14.065

Step-by-step explanation:

First you wanna transfer it from kilometers to miles.

if 1 mile is = to 1.6 kilometers that is the same as saying

1/1.6, but because we are using 90 we plug it in and it becomes: 90/1.6 which gives you 56.25.

now we know we are going 56.25 miles per hour and because we are traveling 4 hours divide the miles per hour by 4 and you get 14.065.

Find the slope of the line that passes through the points (–2, 2) and (13, –7).A. -1.67
B. -0.6
C. 0.6
D. 1.67

Answers

The slope of the line should be -0.6.

Given that,

The points are (–2, 2) and (13, –7).

Based on the above information, the calculation is as follows:

$= (y_2 - y_1) / (x_2- x_1)\n\n= (-7 -2) / (13 + 2)\n\n= -9 / 15$

= -0.6

A stereo salesperson earns a salary of $1900 per month, plus a commission of 4% of sales. The salesperson wants to maintain a monthly income of at least $2200. How much must the salesperson sell each month? PLEASE HELP!!! I WILL GIVE 25 POINTS!!!!!

Answers

percent means parts out of 100
4%=4/100=0.4/10=0.04/1=0.04
4% of sale=0.04 times sales
so we have
at least means >
so
earnings>2200
earnings=1900+comission on sales
commision on sales=0.04 times sales
2200<1900+0.04timessales
solve for sales

2200<1900+0.04 times sales
subtract 1900 from both sides
300<0.04 times sales
divide both sides by 0.04
7500<sales

he has to sell at least $7500 per month
