Answer:
50
Step-by-step explanation:
The length of the midsegment is half the length of the base segment, so you have ...
... 2(6x +2) = 2x +84
... 10x = 80 . . . . . . . . . simplify, subtract 2x+4
... x = 8
The length of the midsegment is 6·8+2 = 50.
Answer:
A) (2+x)/(4+x) × 100 = 75
B) 4
Step-by-step explanation:
2 out of 4
(2+x) out of (4+x)
(2+x)/(4+x) × 100 = 75
(2+x)/(4+x) = 3/4
8 + 4x = 12 + 3x
x = 4
First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
Answer:
There are 20 kids total in the class.
Step-by-step explanation:
15/100 × 20 = 3
You can use direct proportion for any percent calculation.
Compare each number with its percent.
3 i
s 15
% of what number? Let the number be x
So, 3 represents 15
% and x represents 100
%
x/
100
= 3/15
Multiply by 100 to isolate x
x = 
x = 20
Check: 15/
100 × 20 = 3
Answer:
Step-by-step explanation:
1) From AP to PB
we get , from part to part that ,
AP=(1/2)*PB or
PB = 2*AP
2) from part to whole,
AP to AB, we get
AP = (1/3)*AB
or AB = 3*AP
