Answer:
25600cm³
Step-by-step explanation:
We are given these values from the question
The total surface area of shape P is 720 cm².
The total surface area of shape Q is 2880 cm².
The volume of shape P is 3200 cm³
Step 1
Find the scale factor of P to Q in terms of Length, Area and volume
Using the surface area value:
a. Scale factor for length
2880 cm² ÷ 720 cm²
Divide through by 180
= 16 ÷ 4 = 16/4
b. Scale factor for area
√ 16/4=> 4/2
c. Scale factor for volume
(4/2)³
= 64/8
In order to determine the Volume of shape Q , we would multiply the scale factor of the volume by the volume of P
Volume of P = 3200 cm³
Volume of Q =
3200 cm³ × (64/8)
= 25600cm³
D + 146 need to equal 180
e + 125 need to equal 180
d = 180 - 146 = 34
e = 180 - 125 = 55
The speaker is the encoder. That is the correct answer B.
2 corners are both 45 degrees, meaning that they are both the same length.
For this we use the pythagorean theorem, but a bit modified:
a^2 + a^2 = c^2
2a^2 = 256
Solve for a:
a^2 = 128
a = 8 √2
One leg is equal to √128 or 8 √2.
Answer:
We need 4 litres of red paint.
Step-by-step explanation:
We need to take their respective precentages to compare the 3 litres of paint to 8 litres of paint.
Now, we know that the pale purple paint contains 50% red paint, 41.67% blue paint, and 8.33% white paint.
Now, we will transfer these percentages to the 8 litres of paint:
