Answer:
30%
Step-by-step explanation:
Think of this as converting a fraction. 28/40 to x/100. You do this because in the situation, 40 is 100 percent of the price. So 28 is x percent of 100.
You multiply 40 by 2.5 to get to 100, so multiply 28 by the same number to get x. 28 * 2.5 = 70.
So 28 is 70 percent of 40. But the question is asking by what percentage it is discounted. If it's now selling for 70%, it has been discounted 30%. So the answer is 30%

Answer: Table H would be the correct answer;
The rule of a function is that for each x-value given there can't be more than 1 y-value
In Table F:
x = -13, then y = -2
x = -13, then y = 0
x = -13, then y = 5
x = -13, then y = 7
For the x-value -13, there are 4 different y-values, so it's not a function.
In Table G:
x = -6, then y = 3
x = -1, then y = -1
x = -1, then y = 5
x = 10, then y = -9
For the x-value -1, there are 2 different y-values, hence this isn't a function.
In Table H:
x = 1, then y = 4
x = 3, then y = 4
x = 7, then y = 4
x = 12, then y = 4
For each x-value, there is only 1 y-value, so this is a function.
In table J:
x = -9, then y = -7
x = -2, then y = -5
x = 0, then y = 0
x = 0, then y = 6
For the x-value 0, there are 2 different y-value therefore this isn't a function

The amount that a craftsman will charge for an item depends on the
amount that he spends on materials, m, and is determined by the
equation a = 2.5 + 2.5m, where a is the amount charged for each
item. What is the value of the dependent variable, if the value of the
independent variable is 3?
Answer:
$10
Step-by-step explanation:
m is the independent variable, and a the dependent one.
If m = 3, a = 2.5 + 2.5(3) = 10
The craftsman charges $10 when m = 3.

What value of x will make x1/4=3 true?
Answer:
okay so, x would be 12
Step-by-step explanation:
( if you ever see p5 (or any other variable) then that’s means you gotta multiply, so maybe imagine it like px5, p5 would just be a easier way.)
1. x times 1 divided by 4 is 3, a simpler way to put it!
x would be 12 since 12x1 is 12
2. We divide 12 by 4 which gives us a total of 3

The diameter of a circle is 11 ft. Find its area to the nearest tenth.
Answer:
95.0 ft²
Step-by-step explanation:
r = d/2
r = 11/2
r = 5.5
Area of circle formula
a = πr^2
a = π (5.5)²
a = 3.14 * 30.25
a = 94.985
Rounded
a = 95.0
I'm not sure if it's correct but it might 95.03^2ft

In a certain Algebra 2 class of 30 students, 7 of them play basketball and 15 of them
play baseball. There are 10 students who play neither sport. What is the probability
that a student chosen randomly from the class plays basketball or baseball?
Answer:
P=2/3Explanation:
since there are 10 students who play neither sport over 30, this means 20 students play basketball or baseball or both! (among them 2 students who play both basketball and baseball)
∴ the probability that a student chosen randomly from the class plays basketball or baseball is 20/30 and that equals 2/3 or 66.66%
