Answer:
4: 32a^5 5: 2a / bc^2
Step-by-step explanation:
4. (2a)^3 / (2a)^-2
= (2a)^3 * (2a)^2
= 8a^3 * 4a^2
= 32a^5
5. 10a^7 b^9 c^6 / 5a^6 b^10 c^8
= 2a^7 b^9 c^6 / a^6 b^10 c^8
= 2a / bc^2
Answer:
27 girls and 15 boys
Step-by-step explanation:
To solve this, I just used guess and check.
9:5 is a ratio, which means we can multiply each side by any number as long as we do it to both sides.
If we multiply the ratio by 3, we get (9 x 3) : (5 x 3) which is 27:15
And as it turns out, 27-15 is 12, which in this context means there are 12 more girls in drama club, so it works out.
Answer:
530 m²
Step-by-step explanation:
First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]
= 740. − 210
= 530
