Answer:
√134
Step-by-step explanation:
Solve for the top line first,
√(5²+3²)
= √34
then for the dotted line,
√(10²+(√34)²)
= √134
A) .10 d + .25 q = 7.75
B) d + q = 40
Multiplying B) by -.10
B) -.10d -.10q = -4.0
Then adding this to A)
A) .10 d + .25 q = 7.75
.15q = 3.75
Quarters = 25
Therefore, dimes = 15
***************************************************
Double-Check
A) .10 d + .25 q = 7.75
A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75
Correct!!
Answer:
about 116.18
Step-by-step explanation:
Circumference is 2PI*radius
So it should equal 37*3.14 which equals about 116.18
8/18 because just times them by 2 and it will be 8/28.
Step-by-step explanation:
13.6 is the answer because 1cm is 10 cm
