Answer:
A = 120 cm²
Step-by-step explanation:
The 4 part of the ratio relates to the height of triangle A , then
16 ÷ 4 = 4 cm ← value of 1 part of the ratio, then
5 parts = 5 × 4 cm = 20 cm
The area (A) of triangle B is calculated as
A = 
bh ( b is the base and h the height )
Here b = 12 and h = 20 , then
A = × 12 × 20 = 6 × 20 = 120 cm²
Well id like to inform you but you got it right already its 3/4
Because to get your answer you would have to set up the equation 5 and 1/4
divided by 7 which would be 3/4 in a fraction or .75 decimal
Answer:
<h2><u><em>
x = -7</em></u></h2>
Step-by-step explanation:
_3x_13 =_7x+15 what is the anSWER?
assuming that the underscore is a minus and you are looking for the x value.
-3x - 13 = -7 + 15
-3x = -7 + 15 + 13
-3x = 8 + 13
-3x = 21
x = -7
---------------
check
-3 * (-7) - 13 = -7 + 15
21 - 13 = 8
8 = 8
<u><em>the answer is good</em></u>
Answer:
1/2 < 3/5 < 2/3 < 5/6 least to greatest
Step-by-step explanation:
Answer:
20 students should be on each float
Step-by-step explanation:
Number of seniors = 100
Number of juniors = 80
To find number of students that should be on each float, find highest common factor (H.C.F) of 100 and 80
Write prime factorisation of 100 and 80.
100 = 
× 
80 = 
× 5
So,
H.C.F(100, 80) = × 5 = 4 × 5 = 20
Therefore,
20 students should be on each float
