Answer:
52% and 7
Step-by-step explanation:
There are 25 squares of which 13 are shaded , then
[tex]\frac{13}{25}[/tex] × 100% = 13 × 4% = 52°
(b)
1 square represents [tex]\frac{1}{25}[/tex] × 100% = 1 × 4% = 4%
Then 80% = 80% ÷ 4% = 20
That is for 80% , 20 squares require to be shaded
That is 7 more than the 13 already shaded

3b- 4/2 = c , for b
please explain the steps
Answers
Answer:
b = c/3 + 2/3
Step-by-step explanation:
3b - 4/2 = c
the goal is to have b all by itself on one side of the equals sign.
start by moving the fraction over to where c is by adding.
3b = c + 4/2
adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.
Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)
b = c/3 + 2/3
notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3

Answers
Answer:
$2133.33Step-by-step explanation:
Given:
Rate per hour = $6Number of hours = 5Tips = 15%Lets the total amount of tabs = t
We have inequality:
6*5 + 0.15t ≥ 35030 + 0.15t ≥ 3500.15t ≥ 320t ≥ 320/0.15t ≥ 2133.33This is so hard and I don’t know why
Answers
Answer:
Hey girl! I got you.
Step-by-step explanation:
So! The angle x and z are congruent, meaning that they are equal, so you got that part correct. They are indeed 103. Next you need to find y, and in this case you need to do 180 - 103 because the line that holds both angle z and angle y is equal to 180.
180 - 103 = 77, you got that correct also!
You're on the right track, just explain in words how you know what each angle is equal to! Good luck! :)

Find the equation in slope-intercept form of the line parallel to y = 4x + 23 and passes through the point (2,3).
Answers
Answer: y=4x-5
Step-by-step explanation:
The slope of y=4x+23 is:4 m=4
The parallel line needs to have the same slope of 4
Solve it using the "point-slope" equation of a line: y− y1 = 2(x − x1)
substitute or put in the point (2,3):
y − (3) = 4(x − 2)
y - 3 = 4x - 8
put it in slope intercept form y = mx + b
y = 4x − 5

Answer: 3.5 years
Step-by-step explanation: Let A be the salaries earned from company A for x years and B for company B for the same years.
A = 31000 + n*3000
B = 38000 + n*1000
To find the case where A = b, set them to each other and solve for n, the number of years.
31000 + n*3000 = 38000 + n*1000
2000n = 7000
n = (7000/2000) = 3.5 years.

A triangle has angle measures
x+15, 3x-35, and 4x.
What type of triangle is it? Be as specific as possible. Justify your answer.
Answers
(x+15) + (3x-35) + 4x = 180
8x - 20 = 180
8x = 200
x = 25
First angle : x+15 = 25+15 = 40 degrees
Second angle: 3x-35 = 3 * 25 - 35 = 40 degrees
Third angle: 4x = 4 * 25 = 100 degrees.
It is an isosceles triangle since it has two angles (the first end the second one) equal to each other.

Find the x- and y-intercepts of the graph of — 7x + 8y = 40. State your answers as
whole numbers or as improper fractions in simplest form.
Answers
Answer:
x-intercept is (40/7, 0) and y-intercept is (0, 5)
Step-by-step explanation:
x-intercept ==> y-coordinate is 0 ==> y=0
y-intercept ==> x-coordinate is 0 ==> x=0
because the function is 7x + 8y = 40
when y = 0 ==> 7x = 40 ==> x = 40/7
so the x-intercept is (40/7, 0)
when x = 0 ==> 8y = 40 ==> y = 5
so the y-intercept is (0,5)

Samantha has $600 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax,
• She buys a new bicycle for $399,95
• She buys 3 bicycle reflectors for $7.01 each and a pair of bike gloves for $34.06.
• She plans to spend some or all of the money she has left to buy new bilding outfits
for $75,88 each
Write and solve an inequality which can be used to determine w, the number of
outfits Samantha can purchase while staying within her budget
Answers
Answer:
See belowStep-by-step explanation:
The budget is $600.
Samantha spends the following amount:
399.95 + 3*7.01 + 34.06 = 455.04Now, she plans to buy w outfits which cost $75.88 each.
The inequality for this is:
455.04 + 75.88w ≤ 600Solving this we get:
75.88w ≤ 600 - 455.0475.88w ≤ 144.96w ≤ 144.96 / 75.88w ≤ 1.91w = 1 is the only integer solution greater than zero

The rate of change is also known as the slope or rise / run.
Slope Formula: (y2 - y1) / (x2 - x1)
First, we'll need two points that are on the line. You can choose any two points you want, as long as they are on the line.
Point 1 = (0, 1)
Point 2 = (-2, -3)
Then, we'll plug the two points into the formula and solve for the slope.
(-3 - 1) / (-2 - 0)
(-4) / (-2)

The rate of change of this line is 2.

Step-by-step explanation:
y = mx+b
m = slope

now we have y = -2/3x +0
slope is m, so our slope is -2/3
