Each big square below represents one whole. what percent is represented by the shaded area?
Answer:
52 %
Step-by-step explanation:
Total number of squares = 100
Number of shaded squares = 52
% of shaded squares
= ( 52 / 100 ) x 100
= ( 52 x 100 ) / 100
= 5200 / 100
= 52 %
The Parker company employs 68 part time workers. If this represents 4% of the total work force, how many individuals work for the company?
Answer: ite will be 3 bc i done that all ready
Step-by-step explanation:
The number of individuals that work for the company is 272 workers.
Given,
The Parker company employs 68 part-time workers.
This represents 4% of the total workforce.
We need to find out how many individuals work for the company.
What is percentage?Percentage is a fraction or a ratio in which the value of whole is always 100.
Find the total workforce.
Total workforce = 100%
We have,
4% = 68 workers
Multiply 25 on both sides.
25 x 4% = 4 x 68 workers
100% = 272 workers.
This means the number of individuals that work for the company is 272 workers.
Thus the number of individuals that work for the company is 272 workers.

what is the domain of y=x^2-17
Answer:
The Vertex Form of a Parabola is:
g(x) = a(x - h)2 + k
vertex = (h, k)
rate = a (positive is up; negative is down)
a = -1/4 (downward parabola)
vertex = (17, 61)
There is no domain restriction.
Since the parabola is upside down (downward-facing), it reaches it's maximum at its vertex. In other words, is not possible for g(x) to be greater than 61.

A group of activists wants to raise money for a good cause, so they decide to sponsor a bicycle race. It receives $60 per cyclist entry and $15,000 in donations, but it must spend $18 per entry to cover the cost of the race.
Write and solve an inequality to determine the number of cyclists the group needs to raise at least $57,000.
The number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists
Let x represent the number of cyclists.
Since, the activists receive $60 per cyclist entry and $15,000 in donations, hence:
Revenue = 60x + 15000
Also, the cost of the race is $18 per entry, hence:
Cost = 18x
They need to raise at least $57,000, hence:
Profit ≥ 57000
Revenue - Cost ≥ 57000
(60x + 15000) - 18x ≥ 57000
42x ≥ 42000
x ≥ 1000
Therefore the number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists

Answer:
Step-by-step explanation:
1) 6 and -5
x₁ + x₂ = 6 +(-5) = 1
x₁* x₂ = 6*(-5) = -30
x² -(x₁ + x₂)x + (x₁* x₂)=0
x² - x - 30 = 0
2) 4 and 7
x₁ + x₂ =4 + 7 = 11
x₁* x₂ = 4*7 = 28
x² - 11x + 28 = 0
3) 1 and -10
x₁ + x₂ = 1 +(-10) = -9
x₁* x₂ = 1*(-10) = -10
x² - 9x - 10 = 0
4) -9 and 0
x₁ + x₂ = -9 + 0 = -9
x₁* x₂ = 0
x² - (-9)x = 0
x² + 9x = 0
5)2 and 6
x₁ + x₂ = 2 + 6 = 8
x₁* x₂ = 2*6 = 12

Find the value of x if the two triangles are similar. Explain.
Given :
The given two triangles are similar .
To find :-
The value of x .
Solution :
In larger triangle :-
90 + y + y = 180
2y = 180 - 90
2y = 90
y = 45°
As we know that ,
Corresponding Angles of similar triangles are same ,
15x = 45
x = 45/15
x = 3
1. If the lines are parallel, find the measures
of <5 and <6.
122°
5
6
M<5 =
m<6=
Answer:
∠ 5 = 122° , ∠ 6 = 58°
Step-by-step explanation:
∠ 5 and 122° are vertically opposite and are congruent , then
∠ 5 = 122°
∠ 5 and ∠ 6 are same- side interior angles and sum to 180°
∠ 5 + ∠ 6 = 180° , that is
122° + ∠ 6 = 180° ( subtract 122° from both sides )
∠ 6 = 58°

Carlos ate 1/3 of his caramel pie. Carlos is having a friend come over and wants to give her 1/4 of the pie he has remaining. What fraction of the original pie will he give his friend?
===================================================
Explanation:
Multiply the denominators to get 3*4 = 12. We'll use this value to set up the number of slices we start with.
If we started with 12 slices, then 1/3 of this is (1/3)*12 = 4 slices. So Carlos ate 4 slices. There are 12-4 = 8 slices left.
1/4 of that value is (1/4)*8 = 2 which is the number of slices given to his friend.
Divide the number of slices given to the friend (2) over the number we started with (12) to get 2/12 = 1/6
-----------------------
Another approach:
If Carlos ate 1/3 of the full pie, then there are 2/3 of it left.
1/4 of this is (1/4)*(2/3) = (1*2)/(4*3) = 2/12 = 1/6 which represents the fractional amount of the original pie given to the friend.
