Answer: 22
Step-by-step explanation:
(7x+5) + (3x-5) + 90 = 180
10x + 90 =180
-90 -90
10x =90

One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).
Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.
The unit rate is 2,86:2,50
Answer:
48 in
Step-by-step explanation:
The diagonal of the inscribed square equals the diameter of the circle.
1. Calculate the diagonal of the square
d = 2r = 2 × 6√2 in =12√2 in
2. Calculate the side of the square
∆ACB is an isosceles right triangle.
We can use Pythagoras' Theorem to calculate the length of a side s.
3. Calculate the perimeter of the square
P = 4s = 4 × 12 in = 48 in
The perimeter of the square is 48 in.
Answer:
the answer is H because it is h
Solution:
C is the correct graph.
Explanation:
We have been given the graph and we have to tell the type of the graph.
The graph of a quadratic function is a parabola. Hence, the given graph is not the graph of quadratic function.
A linear function represents a straight line. Hence, the given graph is not the graph of linear function.
The graph of a square root function looks like a half parabola. Hence, it must not be the graph of square root function.
The end behavior of a cubic function is "opposite at both ends". We can see that the given graph meets this criteria.
Hence, the given graph represents a cubic function.
C is the correct graph.
