Step-by-step explanation:
t = 4
u = 6 + 2
Find t - u
solu
t - u
= 4 - ( 6 + 2 ) = 4 - 8
Answer is -4
Answer:
Solution given:
The area of a circle =80.86cm²
we have:
The area of a circle =πr²
substituting value of area of circle we get
80.86cm=3.14*r²
dividing both side by 3.14
80.86/3.14=3.14*r²/3.14
25.75=r²
doing square root on both side

r=5.07cm
<u>The</u><u> </u><u>length</u><u> </u><u>of</u><u> </u><u>radius</u><u> </u><u>is</u><u> </u><u>5</u><u>.</u><u>0</u><u>7</u><u>cm</u>
Q18)
7/0.75 = 28/3
28/3(45) = 420 -> 420/60 = 7
Therefore the answer is B. 7 minutes.
Q20)
60.90/5 = 12.18
12.18(7) = 85.26
85.26+14.99 = 100.25
Therefore the answer is D. $100.25.
To me it looks like your right
We have this equation to start with: m/n = 5.5. To achieve the desired equation, you need to multiply the entire equation by n, giving you this equation: m = 5.5n. Hope this helps!
