Answer:
4
Step-by-step explanation:
3/2x -1 = 5
then
3/2x = 5+1
then
3/2x = 6
then
x = 6 / (3/2)
then
x = 6 *2/3
then
x = 4

You throw a ball at a height of 5 feet above the ground. The height h (in feet)
of the ball after t seconds can be modeled by the equation h=-16tsqaured +44t +5
A. After how many seconds does the ball reach a height of 15 feet?
B. After how many seconds does the ball hit the ground? Round your answer
to two decimal places.
Answer:
A. After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. 2.86 sec is the time it takes to hit the ground
Step-by-step explanation:
A. let h = 15
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = .25
After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t. (I will let you do that)
t = 2.85929... or t = -.10929...
t cannot be negative, so 2.86 sec is the time it takes to hit the ground
The answer of A is After 2.5 sec and 0.25 sec the ball was at a height of 15 ft and the answer of B is 2.86 sec is the time it takes to hit the ground.
A. let h = 15
What is the quadratic equation?
[tex]ax^2+bx+c=0[/tex]
a, b, c = known numbers, where a ≠ 0
x = the unknown
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = 0.25
After 2.5 sec and 0.25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t.
t = 2.85929... or t = -.10929...
t cannot be negative, So 2.86 sec is the time it takes to hit the ground.

Riley took 5 tests in science. Each test had a different score. The mean score of the tests was 90%. The median score of the tests was 85%. Based on this information, select the two statements that must be true.
A: More than half of the scores were 85% or greater.
B: More than half of the scores were 90% or greater.
C: There were no scores less than 85%
D: There were no scores less than 90%
E: At least one score was exactly 85%
F: At least one score was exactly 90%
Answer:
A: More than half of the scores were 85% or greater.
E: At least one score was exactly 85%
Step-by-step explanation:
Here the 5 test would be taken in science so 85% would be the result of one of the test
Also 85% represent the median so it means there are 2 values more and 2 values less
So there are 3 results with 85% or greater
Hence, the option A and Option E is correc

Answer:
17. See below
18. 750
Step-by-step explanation:
17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.
18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:
[tex]y=0.5x+125[/tex]
Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:
[tex]500=0.5x+125[/tex]
[tex]500-125=0.5x[/tex]
[tex]375=0.5x[/tex]
[tex]\frac{375}{0.5} =x[/tex]
[tex]375*2=x[/tex]
[tex]750=x[/tex]
Thus, 750 lollipops must be sold.

Answer:
A and B (answer #2)
Step-by-step explanation:
right triangles: c^2 = a^2 + b^2
c is the largest side
for A: c = 5, a = 3, b = 4
5^2 = 3^2 + 4^2
25 = 25, so A is a right triangle
for B, c = 13, a = 5, b = 12
13^2 = 5^2 + 12^2
169 = 169, so B is a right triangle
for C, c = 4, a = 2, b = 3
4^2 = 2^2 + 3^2
16 ≠ 13, so C is not a right triangle
So, A and B are right triangles.
