A total of 20 families participate in a car wash. Each family brings two cars. Mr. Gonzales notices that 35% of the cars were minivans. How many minivans were washed?
Answer:
14 minivans
Step-by-step explanation:
From the question
A total of 20 families participate in a car wash. Each family brings two cars.
Hence, the total number of cars brought to the car wash is:
20 × 2
= 40 cars.
Mr. Gonzales notices that 35% of the cars were minivans.
The number of minivans were washed is :
35% of the total number of cars
= 35/100 × 40
= 14 minivans
Hence, 14 minivans were washed

In Δ A B C, the measure of the largest angle is 32 less than 3 times the smallest angle. The measure of the middle angle is 8 more than half the measure of the largest angle. What is the measure of the middle angle?
Answer:
52degrees
Step-by-step explanation:
Let the measure of the largest angle be x
middle angle be y
smallest angle be z
Since the sum of angle in a triangle is 180 degrees, hence;
x + y + z = 180 .... 1
If the measure of the largest angle is 32 less than 3 times the smallest angle, then;
x = 3z - 32
3z = x+ 32
z = x+32/3 ..... 2
If he measure of the middle angle is 8 more than half the measure of the largest angle, then;
y = x/2 + 8 .... 3
Substitute 2 and 3 into 1;
x + x/2 + 8 + (x+32)/3 = 180
multiply through by 6
6x + 3x + 48 + 2(x+32) = 1080
9x + 48 + 2x + 64 = 1080
11x + 112 = 1080
11x = 1080-112
11x = 968
x = 968/11
x = 88 degrees
Get the middle angle y;
Since y = x/2 + 8
y = 88/2 + 8
y = 44 + 8
y = 52 degrees
Hence the measure of the middle angle is 52degrees
The angles in a triangle add up to 180 degrees.
The middle angle is 52 degrees
Let the largest, middle angle and the smallest angle be x, y and z
From the question, we have:
[tex]\mathbf{x = 3z -32}[/tex]
[tex]\mathbf{y = 8 + \frac 12x}[/tex]
Make z in [tex]\mathbf{x = 3z -32}[/tex]
[tex]\mathbf{z =\frac{x + 32}{3}}[/tex]
The angles in a triangle add up to 180 degrees.
So, we have:
[tex]\mathbf{x + y + z = 180}[/tex]
Substitute the expressions for y and z in [tex]\mathbf{x + y + z = 180}[/tex]
[tex]\mathbf{x + 8 + \frac 12x + \frac{x+32}{3} = 180}[/tex]
Multiply through by 6
[tex]\mathbf{6x + 3x + 48 + 2(x+32) = 1080}[/tex]
[tex]\mathbf{9x + 48 + 2(x+32) = 1080}[/tex]
Open brackets
[tex]\mathbf{9x + 48 + 2x + 64 = 1080}[/tex]
Evaluate like terms
[tex]\mathbf{11x + 112 = 1080}[/tex]
Subtract 112 from both sides
[tex]\mathbf{11x = 968}[/tex]
Divide both sides by 11
[tex]\mathbf{x = 88}[/tex]
Substitute 88 for x in [tex]\mathbf{y = 8 + \frac 12x}[/tex]
[tex]\mathbf{y = 8 + \frac{88}2}[/tex]
[tex]\mathbf{y = 8 + 44}[/tex]
[tex]\mathbf{y = 52^o}[/tex]
Hence, the middle angle is 52 degrees

NEED THIS ASAP!!
Answer:
A
Step-by-step explanation:
The inverse of the given function is (6x + 2)/3.
What is the inverse of a function?"The inverse of a function is a function that undoes the operation of that function. The inverse of a function exists if and only if the function is bijective"
Given function is
F(x) = (3x - 2)/6
⇒ y = (3x - 2)/6
If we write 'x' instead of 'y' and 'y' instead of 'x', then we get:
x = (3y - 2)/6
⇒ 6x = (3y - 2)
⇒ 3y = 6x + 2
⇒ y = (6x + 2)/3
Therefore, F⁻¹ (x) = (6x + 2)/3

Jake scored 2 goals in soccer this season. Jaime scored 4 times as many goals as Jake. Edgar scored 3 times as many goals as Jaime. How many goals did Edgar score?
Answer:
Edgar scored 24 goals in soccer this season.
Step-by-step explanation:
Proportions
We can calculate the number of goals scored by Edgar this season if we follow the relationships given in the problem.
First, we know jake scored 2 goals. Also, we know Jaime scored 4 times as many goals as Jake.
This means Jaime scored 2*4 = 8 goals.
Finally, we know Edgar scored 3 times as many goals as Jaime.
Then, Edgar scored 8*3 = 24 goals.
Edgar scored 24 goals in soccer this season.

Which of the following statements best explains why this graph represents a relation that is not a function
Answer:
i think it’s “ the x values between 1 & 3 are each paired with multiple y values “
Step-by-step explanation:
The given relation is not a function because input value 1 and 3 have more than one value
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
As, we know if the relation is function then it's input value is distinct.
From the graph we can se that the input value 1 and 3 have more than one value
As, input 1 ----> {1.1, -1.1}
and, input 3 ----> {0, -2.5}
Hence, the given relation is not a function.

Latrell took one of his friends out to lunch. The lunches cost $60 and he paid 5% sales tax. If Latrell left a 15% tip on the $60, how much in total did he pay?
Answer:
$72
Step-by-step explanation:
Cost of the lunch = $60
Sales tax = 5% of $60
= 5/100 × 60
= 0.05 × 60
= $3
Tip = 15% of $60
= 15/100 × 60
= 0.15 × 60
= $9
how much in total did he pay?
Total amount paid = cost of the lunch + sales tax + tip
= $60 + $3 + $9
= $72
Latrell paid $72 in total for the lunch
Andrew had a collection of 300 baseball cards at the beginning of the summer After the summer Andrew had traded some of his baseball cards and know he only has 213 baseball cards What percent is the decrease of his baseball cards collected
Answer:
The percentage decrease is 29%
Step-by-step explanation:
Given
[tex]Initial = 300[/tex]
[tex]Final = 213[/tex]
Required
Determine the percentage decrease
This is calculated as thus:
[tex]\%Percentage = \frac{|Final - Initial |}{Initial} * 100\%[/tex]
Substitute values for Final and Initial
[tex]\%Percentage = \frac{|213 - 300|}{300} * 100\%[/tex]
[tex]\%Percentage = \frac{|-87|}{300} * 100\%[/tex]
Get absolute value of -87
[tex]\%Percentage = \frac{87}{300} * 100\%[/tex]
[tex]\%Percentage = \frac{87* 100\%}{300}[/tex]
[tex]\%Percentage = \frac{8700\%}{300}[/tex]
[tex]\%Percentage = 29\%[/tex]
Hence, the percentage decrease is 29%
