Hey there!
When dealing with percent word problems, the word "is" means equals. Let's see what we can do with your problem.
If the small school had 60% boys, it will have 40% girls. The number of boys <em>is</em> 48, which should equal 60% of the total, which we can model below, with t representing the total number of kids. In decimal form, 60% is 0.6.
0.6t=48
We divide both sides by 0.6.
t=80
Therefore, there are 80 total kids at the school.
We can also check our answer below.
BOYS: 0.6(80)= 48
GIRLS: 0.4(80)=32
48+32=80
I hope that this helps!
Answer:
sin = √2/2, cos = -√2/2, tan = cot = -1
csc = √2, sec = -√2
Step-by-step explanation:
Angle runs around unit circle (where x^2+y^2=1)
from (1,0) to (-√2/2,√2/2)
Answer:
y = - x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here slope m = - 1 and y- intercept c = - 5, hence
y = - x - 5 ← equation of line
Answer: D) Front - $35.00 Back - $22.50
Step-by-step explanation:
b+12.5=f
600f+450b=31,125
Substitute
600(b+12.5)+450b=31,125
Distribute
600b+7500+450b=31,125
Combine like terms
1050b+7500=31125
Subtract 7500
1050b=23625
Divide by 1050
b=22.5
Thus, the back tickets cost $22.50.
