Answer:
42 students
Step-by-step explanation:
A percentage can be converted to a decimal. 30% -> 0.30.
Now multiply 60x0.30, which is 18.
So 18 were wearing sweatshirts. But that's not what we need.
Subtract 60-18, which is 42.
42 were not wearing sweatshirts.

The perimeter of a rectangular parking lot is 308 m.
If the length of the parking lot is 88 m, what is its width?
Answer:
66
Step-by-step explanation:
perimeter= 2(l+b)
2(88+b)=308
176+2b=308
2b=308-176
2b=132
b=66

The graph of h is the graph of f(x) = x² translated 6 units left and 12 units up. It is also reflected over the x-axis and compressed vertically by a factor of 1/2.
Write h(x) in vertex form.
what is the value of x in the equation x^3=0.64
A.0.04
B.0.4
C.4
D. .08
D
since you are finding for X, and not x^3. Take cubic root of both sides to eliminate the index or power of 3. The cubic root of 0.64 is 0.861 approximately 0.9

Two families went to the event. The first family bought two children's tickets and one adult ticket and paid a total of 8.2 euros. The other family bought three children's tickets and two adult tickets and paid a total of 14.1 euros. Can you tell me how much one child costs and how much one adult ticket costs?
Answer:
Step-by-step explanation:
step a system of two equations c = child ticket a = adult ticket
eq 1) 2c + 1a = 8.2 multiply by 2
eq 2) 3c + 2a = 14.1
I will multiply eq 1 times TWO and subtract eq 2 from eq 1a)
eq 1a) 4c + 2a = 16.4
eq 2) 3c + 2a = 14.1
subtract (4c - 3c) + (2a -2a) = 16.4 - 14.1
c + 0 = 2.3 euros for one child ticket
Now find the adult ticket price, plug 2.3 for c into eq 1)
eq 1) 2c + 1a = 8.2
eq 1) 2(2.3) + 1a = 8.2 solve for a
4.6 + a = 8.2 substract 4.6 from both sides
a = 8.2 - 4.6
= 3.6 euros for one adult ticket
double check using eq 2) we know c and a values
eq 2) 3c + 2a = 14.1
eq 2) 3(2.3) + 2(3.6) = 14.1
6.9 + 7.2 = 14.1
14.1 = 14.1

Use the property of parallelograms to solve for the missing variable
Answer:
x = 30, y = 6
Step-by-step explanation:
Here, we want to use the property of parallelograms
mathematically, the lengths of the parallel sides are equal
This mean:
2y + 3 = y + 9
2y - y = 9-3
y = 6
To get x;
Angles that face each other are supplementary; meaning they add up to 180
Thus, we have that
4x + 2x = 180
6x = 180
x = 180/6
x = 30
-4(y-2)=12 help please
Answer:
-2
Step-by-step explanation:
(y-2)=-(12/4)
y-2= -4
y= -4+2
y = -2
Answer:
y = -1
Step-by-step explanation:
1. -4(y - 2) = 12
2. -4y + 8 = 12
3. -4y + 8 = 12 - 8
4. -4y = 4
5. -4y/-4 = 4/-4
6. y = -1
Check your answer:
-4(y - 2) = 12
-4(-1 - 2) = 12
4 + 8 = 12 True

You told your friend that you could eat 5/8 of a large pizza. If you only ate 1/2 of what you said you could eat, what fraction of a large pizza did you eat?
Answer:
5/16
Step-by-step explanation:
Given that:
Fraction of claim = 5/8
Amount actually eaten = 1/2 of claim
Amount actually eaten = 1/2 * 5/8 = 5/16
Fraction of large pizza actually eaten is 5 /16
Hence, he ate, 5/16 of large pizza
