Step-by-step explanation:
The "trick" to this problem is knowing that opposite sides of the box add up to 180°
Now that you know that maybe you can solve this?
180= 7x+2 + 6x-4
180 = 13x -2
182 = 13x
14 = x
find y now to find all the angles
180 = 2y + 4 +4y - 4
180 = 6y
30 = y
now solve the x expressions and the y expressions
7x+2

The athletic department manager purchased a total of 52 footballs and soccer balls. Each football cost $23.53, and each soccer ball cost $19.86. If the manager spent a total of $1,120.80, how many soccer balls did the manager purchase?
Answers
Answer:
The manager purchased 28 soccer balls.
Step-by-step explanation:
Since the information states that the athletic department manager purchased a total of 52 balls, you can say that the result of adding up the number of footballs and soccer balls purchased is 52, which can be expressed as:
x+y=52, where:
x is the number of footballs purchased
y is the number of soccer balls purchased
Also, as the statement indicates the price of each type of ball and the total cost, you can say that adding up the results of multiplying the price of each ball for the quantity purchased is equal to the total amount spent, which is:
23.53x+19.86y=1,120.80
Now, you have 2 equations:
x+y=52 (1)
23.53x+19.86y=1,120.80 (2)
To be able to find the value of x and y, first you can isolate x in (1):
x=52-y (3)
Then, you can replace (3) in (2) and solve for y:
23.53(52-y)+19.86y=1,120.80
1,223.56-23.53y+19.86y=1,120.80
1,223.56-1,120.80=23.53y-19.86y
102.76=3.67y
y=102.76/3.67
y=28
Finally, you can replace the value of y in (3) to find the value of x:
x=52-28
y=24
According to this, the answer is that the manager purchased 28 soccer balls.
The cost of electricity is obtained as follows: A fixed charge of $(a), rent of a meter $(b) and a charge of (c) cents for unit of electricity supplied Determine the total cost of using n units of electricity.
Answers
Answer:
$(a + b) + cn cent
Step-by-step explanation:
Given :
Fixed charge = $a
Rent of a meter = $b
Charge per unit of electricity = c cents
The total cost of using n units of electricity :
For n units of electricity ;
Fixed charge is paid once
Meter rent is paid once
The cost of electricity = (number of units * cost per unit) = (n * c) = nc cents
Total cost of n units of electricity :
$(a + b) + cn cent

Pressure under water is found to be 237 pounds per square foot
Now, put P = 237 to find d. So,
[tex]237=13+\dfrac{8}{13}d\\\\237-13=13+\dfrac{8}{13}d-13\\\\224=\dfrac{8}{13}d\\\\d=\dfrac{224\times 13}{8}\\\\d=364\ ft[/tex]
So, the depth is equal to 364 feet.
Write the fraction 24/40 in its simplest form.
Answers
Answer:
3/5
Step-by-step explanation:
The numerator, 24, and the denominator, 40, both have a GCF(greatest common factor) of 8. By dividing both the numerator, 24, and the denominator, 40, by 8 you would be simplify the fraction. In which you'd get a numerator of 3 and a denominator of 5, which is 3/5 and the simplest form of 24/40.
The simplified form of 24/40 is 3/5.
To simplify the fraction 24/40, we need to find the greatest common factor (GCF) of the numerator (24) and the denominator (40) and then divide both the numerator and denominator by that GCF.
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24.
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40.
Looking at the lists of factors, we can see that the greatest common factor of 24 and 40 is 8.
To simplify the fraction, we divide both the numerator and denominator by 8:
24 ÷ 8 = 3
40 ÷ 8 = 5
Therefore, the simplified form of 24/40 is 3/5.
The simplified fraction represents the same proportion as the original fraction but is written in its simplest and most reduced form. In this case, 24/40 can be simplified to 3/5 by dividing both the numerator and denominator by their greatest common factor, which is 8.
