Answer:
0.96%
Step-by-step explanation:
Well the easy way to do this is
1.262
- - - - - - - x 100 = 100.96%
1.25
( this is just saying, now the thing is 100.96% of it original size)
So now they are asking the increase, so just simply take
100.96 - 100
= 0.96%
Answer:
272 cm²
Step-by-step explanation:
Step 1
We have to find the scale factor
When given the volume of two solids, the formula for the scale factor is
V1/V2 = (Scale factor)³
The volume of Pyramid A is 704 cm³ and the volume of Pyramid B is 297 cm³
V1 = Pyramid A
V2 = Pyramid B
704/297 = (scale factor)³
We simplify the left hand side to simplest fraction
The greatest common factor of 704 and 297 = 11
704÷11/297÷11 = (scale factor)³
64/27 = (scale factor)³
We cube root both sides
cube root(scale factor)³ = cube root (64/27)
scale factor = (4/3)
Step 2
(Scale factor)² = S1/S2
S1 = Surface area of Pyramid A =?
S2 = Surface area of Pyramid B = 153 cm²
Hence,
(4/3)² = S1/153
16/9 = S1/153
Cross Multiply
S1 × 9 = 16 × 153
S1 = 16 × 153/9
S1 = 272 cm²
Therefore, the Surface Area of Pyramid A = 272 cm²
Step-by-step explanation:
7 years
leap years in 7 years:- 1
7 minus 1 equals to 6
6 calendar years to days:- 2190 days
so, $0.75 times 2190 = $1642.5
1642.5 plus $4.35 equals to 1646.85

Answer:
1
Step-by-step explanation:
If 3m + 5 = 8
We can say 8 - 5 = 3m
So, 3 = 3m
So, m = 1.
1 x 3 = 3!
