i think it is 487.5. i may be wrong tho. hope this helps!
Let the number be a ...
i.e ,70% of a =126 ..
=> 70/100 X a =126
=>7/10 a =126
=>7 a = 126 X 10
=>7 a= 1260
=>a = 1260/7
a = 180 ..
Hope it helps !!!
The perimeter of the rectangle is by definition:
P = 2W + 2L
Where,
W: width
L: long
We have then:
P = 2 (5.5 * 6) +2 (5.5 * 8)
P = 154 cm
The area of the rectangle is by definition:
A = (W) * (L)
Where,
W: width
L: long
We have then:
A = (5.5 * 6) * (5.5 * 8)
A = 1452 cm ^ 2
Answer:
Perimeter = 154 cm, area = 1,452 cm2
Answer:
54 degrees and 90 degrees
Step-by-step explanation:
If you add up all the angles in a triangle it will equal 180 degrees. So first, subtract 36 from 180
180 - 36 = 144
If the other two angles have a ratio of 3 to 5 then you need to divide 144 by 8 because 3 + 5 = 8
144/8 = 18
Then multiply 18 by 3 and 5. This will give us the measurement of the other two angles.
18 x 3 = 54
18 x 5 = 90
90 + 54 + 36 = 180
Answer:
70% or 175 students
Step-by-step explanation:
3/10 is equivalent to 30/100 which is the same thing as 30 percent
