I think that the 2 or 4 one are right. This one is hard for me too but just hope that you get right and hope that it is right.
97 rounds up to 100
78 rounds up to 80
100x80= 8,000
estimate=8,000
97x78=7,566
product=7,566
Answer:
56cm is not the answer for sure trust me
Step-by-step explanation:
I took the test so dont worry!
Refer to c^2=a^2+b^2 (^2 means squared)
C is the hypotenuse and will be the longest measure
So 15^2= 9^2+12^2
225=225
If both sides are equal then the triangle is a right triangle, if the hypotenuse (or c) is lower or higher than you can determine whether it’s obtuse or acute
It would be a right triangle
Answer:
32 × 10^(10k)
Step-by-step explanation:
y = 16 x 10^8k
y^5/4 = ⁴√y^5
= ⁴√16^5 x 10^40k
= ⁴√2^20 x 10^40k
= 2^5 × 10^10k
= 32 x 10^(10k)
