Answer: c) 1 1/4
Step-by-step explanation: you do 1/4 times 5 .You make 5 a fraction which is 5/1.So now you do 1/4 times 5/1 which is 5/4.And you change it to a mixed number which is 1 1/4.
It would be 12 ones it would be this because you have to add 7+ 5

There is no exact answer to this. It will have to shown in terms of the width. Also we need to use the Pythagorean Formula
Givens
L = 10 * W
W = W
Formula
L^2 + W^2 = C^2
Solution
(10W)^2 + (W^2) = C^2
C^2 = 100W^2 +W^2
C^2 = 101W^2 Now take the square root.
C = sqrt(101W^2)
C= W*sqrt(101) <<<<< Answer. I think this is what they mean
The answer is: [B]: " -10a + 6b² − 4b + 3 " .

Explanation:
____________________
Given:
____________________________
-2(5a − 3b²) − 4b + 3 ;
_________________________________
"Use the distributive property [of multiplication] to expand the expression."
______________________________________________
Note the distributive property of multiplication:
______________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
______________________________________________
So, we have: " -2(5a − 3b²) − 4b + 3 " ;
______________________________________________
Start with: " -2(5a − 3b²) " ;
______________________________________________
-2(5a − 3b²) = (-2*5a) − (-2*3b²) = (-10a) − (-6b²)
= -10a + 6b²
________________________________________________
→ Now, bring down the rest of the problem;
________________________________________________
-10a + 6b² − 4b + 3 ; which is: Answer choice: [B].

A percent between 25 and 50 can be 35%
35% as a decimal is 0.35
35% as a fraction = 35/100
35/100 simplest form = 7/20
hope this helps
