Answer:
15 rounds
Step-by-step explanation:
Change 75% into a decimal (0.75).
Multiply 20 by 0.75.
When doing so, you get 15 rounds.
To check this: 15/20 = 3/4 = 0.75
17/12 because 17 is a prime number and can't be simplified
Answer:
the number is 25
Step-by-step explanation:
If the number is n, then twenty-two more is n + 22
which equals 47, so n+ 22 = 47
n = 47 - 22 = 25

Answer: Choice B</h3>
y = x+9 because the y-intercept of the function represented by the table is 5.
============================================================
Explanation:
Let's focus on the first two rows of the table. Plug those coordinates into the slope formula below.
m = (y2-y1)/(x2-x1)
m = (13-9)/(4-2)
m = 4/2
m = 2
The slope is 2.
Then we'll use something like (x,y) = (2,9) along with the slope we found to determine the y intercept b
y = mx+b
y = 2x+b
9 = 2*2+b
9 = 4+b
9-4 = b
5 = b
b = 5
The equation for the table is y = 2x+5
We can check this by seeing that x = 6 leads to y = 2*x+5 = 2*6+5 = 17. I'll let you check the other x values of the table.
Because y = 2x+5 has a y intercept of 5, we're going to aim for answer choice B. The y intercept of y = x+9 is 9 which is larger than what we just found.
The distance between the two given points (28,-12) and (28,6) is 18.
<h3>What is the distance between the two given points?</h3>
Formula for the distance between two points is expressed as;
D = √( ( x₂ - x₁)² + ( y₂ - y₁ )²
Given the data in the question;
For point (28,-12)
For point (28,6)
We plug in the values into the formula above.
D = √( ( 28 - 28)² + ( 6 - (-12) )²
D = √( ( 0 )² + ( 6 + 12 )²
D = √( 0 + ( 18 )² )
D = √( 0 + 324 )
D = √( 324 )
D = 18
Therefore, the distance between the two given points (28,-12) and (28,6) is 18.
