Heather is a software saleswoman. her base salary is 1900, and she makes an additional $40 for every copy of math is fun she sells.
let P represent her total pay (in dollars) and N represent the number of copies of math is fun she sells. write and equation relating P to N and use this equation to find her total pay if she sells 27 copies of math is fun. ​

Answers

Answer:

[tex]P = 1900 + 40N[/tex]

[tex]P = 2980[/tex] when N = 27

Step-by-step explanation:

Given

[tex]Base\ Salary = 1900[/tex]

[tex]Additional = 40[/tex] per copy

Solving (a): Her total pay (P)

This is represented by:

[tex]P = Base\ Salary + Additional * N[/tex]

[tex]P = 1900 + 40 * N[/tex]

[tex]P = 1900 + 40N[/tex]

Solving (b): Total pay when N = 27

Substitute 27 for N

[tex]P = 1900 + 40 * 27[/tex]

[tex]P = 1900 + 1080[/tex]

[tex]P = 2980[/tex]

Great Falls is at approximately 47.5 degrees N, and 111.3 degrees W. Lemhi is approximately 45.5 degrees N, and 113.5 degrees W. (We will assume the rivers flow straight from Great Falls to Lemhi on the surface of Earth). Apply the Law of Cosines for Sides of a spherical triangle to find the angle between Great Falls and Lemhi.

Answers

Answer:

The angle between Great Falls and Lemhi is approximately 3.02°

Step-by-step explanation:

The location parameters are;

The Great Falls location = 47.5° N, 111.3° W

The location of Lemhi = 45.5 °N and 113.5 °W

Therefore, we have;

The angle between the Great Falls and the poles, AP = 90° - 47.5° = 42.5°

The angle between Lemhi and the poles, PB = 90° - 45.5° = 44.5°

The angle between the lines of longitude, P = 113.5° - 113° = 0.5°

By the law of cosines for Sides of a spherical triangle, we have;

CosAB = cos AP·cosPB + sinAP·sinPB·cosP

Where;

AB = The angle between Great Falls and Lemhi

∴ CosAB = cos(47.5°) × cos(44.5°) + sin(47.5°) × sin(44.5°) × cos(0.5°) ≈ 0.9986

AB ≈ arccos(0.9986) ≈ 3.02°

The angle between Great Falls and Lemhi ≈ 3.02°

what is the answer (31-19)×2+10​

Answers

we want to follow PEMDAS
we will start with parentheses
31-19 = 12
So now we have 12 x 2 + 10
We then want to multiply
12 x 2 = 24
So now we have 24 + 10
24 + 10
So our final answer is 34
31-19=12 12x2=24 24+10 = 34 . remember pemdas

The basketball coach spent $35 on 5 t shirts for his team last season. This season, he needs to purchase 7 t shirts. If he pays the same rate as last year, how much will the t shirts cost?

Answers

Answer:

5 dollars

Step-by-step explanation:

last year he got 5 they were 7 dollars because 7x5 is 35 so do the same thing to do other it also equals 35

ok so he bought 5 last season and spent 35 last time. we first need to find how many each was for last season. we can do this by dividing 35 and 5.

so 35/5

is 7

the next season he needs to have 7,

2 more then the prior season.

we now know each t shirt is the same price as last season it’ll be $7 each.

so you’d multiply 7x7 which is

$49

final answer: $49

hope this helps!

The equation of the line is y=-1/2x-3.5

Step-by-step explanation:

Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex].

[tex]m=\frac{-5-(-4)}{3-1} =\frac{-5+4}{3-1} =\frac{-1}{2}[/tex]

After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.

[tex]-4=\frac{-1}{2} (1)+b[/tex]

[tex]\frac{1}{2} -4=\frac{-1}{2} +\frac{1}{2} +b[/tex]    add both sides by 1/2 so that b is alone

[tex]\frac{-7}{2} =b[/tex]              

You can rewrite -7/2 as -3.5.

For calculating the 50th term , n = 50

Now

[tex]t_{50} = a + ( n - 1) d\\t_{50} = 29 + ( 50 - 1 ) *3\\ t_{50} = 29 + 147\\t_{50} = 176[/tex]

Use the coordinates of two points to find the slope of the line.

Slope of line through (2,5) and (0,1) = (5-1)/(2-0) = 2

(0,1) is a point on the line, so the y-intercept is 1.

Slope-intercept equation of the line: y = 2x+1

x = -2, y = -3

x = ½, y = 2
