There are 8 boys for every 3 girls at a concert. If there are 220 people at the concert, what is the difference between the total number of boys and girls at the concert?
Answers
Answer:
100
Step-by-step explanation:
First we get the ratio of 8:3 for the amount of boys to girls.
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 8 + 3 = 11
Part A = 8 and Part B = 3 are numerators for each fraction.
The fractions are then:
8/11 and 3/11
8/11 for boys
and 3/11 for the girls
Now we just multiply 220 by these fractions:
220 * 8/11 = 160
220 * 3/11 = 60
Then subtract:
160 - 60 = 100
Answer:
There are 60 girls and 160 boys

Answers
Answer:
Step-by-step explanation:
1) x +22.5 = 49.25
Subtract 22.5 from both sides
x + 22.5 - 22.5 = 49.25 - 22.5
x = 26.75
Checking: LHS = x + 22.5 = 26.75 + 22.5 = 49.25 = RHS
2) 37.2 = n - 12
Add 12 to both sides
37.2 + 12 = n - 12 + 12
49.2 = n
n = 49.2
3) 55t = 176
Divide both sides by 55
[tex]\frac{55t}{55}=\frac{176}{55}\\\\t = 3.2[/tex]
Samantha went to a bike store to purchase a new bike. The store was having a sale. If the total purchase, not including tax was over $200, you got 25% off your purchase.

Calculate the volume of this rectangular prism below.
A) 14/27 cubic cm
B) 4_ 1/3 cubic cm
C) 14/9 cubic cm
D) 4 cubic cm
Answers
Answer:
A) 14/27 cubic cm
Step-by-step explanation:
Volume of a rectangular prism is length x width x height
Volume = 2 1/3 x 2/3 x 1/3
I'd convert the 2 1/3 to an improper fraction to keep things consistent = 7/3
7/3 x 2/3 x 1/3
multiply the numerators: 7 x 2 x 1 = 14
multiply the denominators: 3 x 3 x 3 = 27
14/27 cubic cm

A line passes through the point (6,20) and has a slope of 2. Create an equation in the form of y= mx +b
Answers
Answer:
y=2x+8
Step-by-step explanation:
y=mx+b is slope-intercept form
y - y-coordinate
m - slope
x - x-coordinate
b - y-intercept
If the slope is 2, then m will be replaced by 2. The y-intercept is the pair of points in which the x-coordinate is 0. There is probably a quicker way to solve this, but this is how I ended up finding what y-coordinate corresponds with the x-value of 0.
(6,20)
(5,18)
(4,16)
(3,14)
(2,12)
(1,10)
(0,8)
Since the y-intercept is (0,8), b will be 8.
