Answer:
A. Ratio boys to girls ---> 19 : 26
B. Ratio of 5th grade to 6th grade ---> 21 : 24
C. Ratio of girls to total number of chorus students ---> 26 : 45
Step-by-step explanation:
A. the amount of boys is 9 + 10, the amount of girls is 12 + 26
B. the amount of 5th graders is 12 + 9, the amount of 6th graders is 14 + 10
C. the number of girls is 12 + 14, and the number of chorus students is 12+9+14+10
Answer:
Nothing
Step-by-step explanation:
There are no numbers that when multiplied will equal 8, and can be added to equal 12.
Let m = 10 and n = 2
We know:
y^2 = (m+n).m
y^2 = (10+2).10
y^2 = 120
y = √(120)
Then,
m^2 + x^2 = y^2
10^2 + x^2 = ( √( 120) )^2
100 + x^2 = 120
x^2 = 120 - 100
x^2 = 20
x = √(20)
x = √(4×5)
x = √(4) × √(5)
x = 2√(5)
I hope this has helped!
Answer:
-70
Step-by-step explanation:
This is not an expression due to the =, because that makes it an equation. So I will assume the = is a +, to make it an expression.
1. Combine all negative numbers: -68 - 4 - 3 = -75
2. Add to 5, -75 + 5 = -70
A^2+b^2=c^2
8^2+b^2=17^2
64+b^2=289
b^2=225
b=15
The TV would be 14 inches tall.
( I used Pythagorean theorem )
note: TVs are advertised by the length going diagonally across
