Answer:
± 7
Step-by-step explanation:
Given
d = 
, then
d = 7 or - 7, that is ± 7
Since 7 × 7 = 49 and - 7 × - 7 = 49
To find the circumference of a semi-circle, it would be 1/2<span> π × d. So, pi (3.14) times the diameter, 5 would be 15.7, but then we would need to multiply it by 1/2 to get the circumference for half the circle, and that will get you 7.85. Now you can add all the lengths now. 7.85 + 7 + 5 + 7 = 26.85. Hope this helps! Let me know if you still don't get it. <3</span>
Answer:
6 hours
Step-by-step explanation:
180 divided by 30 = 6
x=4 y=5
if we put two pharases together
the answer is as follows pic :
x=4 y=5
since the equation is c=9.5t, Sanjay paid c=9.5 x 14 shirts he bought. which =$133
