The rules are
Let me show you why with a couple of examples: suppose we want to multiply
Since powers are just repeated multiplications, we have
Similarly, we have
Answer:
The value of x is D. 37°
Step-by-step explanation:
No need for math on this one, the angle next to x is 71° and is significantly bigger, so the only answer could be 37°.
Answer:
10:7
Step-by-step explanation:
40:28 are both divisible by 4. 40/4 is 10. 28/4 is 7. So the ratio would be 10:7 since neither is divisible by both the same number, this is the final ratio.
Answer:
SA = 664 in.²
Step-by-step explanation:
Surface area of the rectangular prism = 2(LW + LH + WH)
Where,
Length (L) = 16 in.
Width (W) = 5 in.
Height (H) = 12 in.
Substitute the values
Surface area of the rectangular prism = 2(16*5 + 16*12 + 5*12)
= 2(80 + 192 + 60)
= 2(332)
= 664 in.²
Yy^2 I'm pretty sure is the answer!
