Answer:
D
Step-by-step explanation:
D is correct because the sqrt of 91 is 9.5 and 9<9.5<10 makes absolute sense
C is not correct because the sqrt of 33 is 5.7 and 6<5.7<7 does not make sense
B is not correct because the sqrt of 13 is 3.6 and 4<3.6<5 does not make sense
A is not correct because the sqrt of 65 is 8.06 and 7<8.06<8 does not make sense
Yes I do believe they are similar.
Here we have to know the conversion between feet and inches.
1 Feet = 12 inches (This is given and is to be known)
So the 5 feet wide footbridge when converted to inches would be about 5*12 = 60 inches
The width of the footbridge in inches = 60 inches
Each wooden plank is 6 inches,
So the number of wooden planks that are required to build the foot bridge of 60 inches = 60/6 = 10 planks
Hence, the path path is 10 planks wide
Step-by-step explanation:
first do prime factorization of 324= 2×2×3×3×3×3
= 2 square, 3 square,3 square
therefore 324 is a perfect square
Now,
prime factorization of 588=2×2×3×7×7
= 2 square,7 square ,3
therefore 588 is not a perfect square
Amount from dimes would be: 0.1y
Amount from quarters = 0.25x
So, total amount = 0.25x + 0.1y
So, she is not correct
Hope this helps!
