<span><u><em>Answer:</em></u>
83.21 mm.<span>
<u><em>Explanation:</em></u>
<u>Circumference of a circle is is found by using the formula:</u>
C=πd.
C is the Circumference.
d is diameter.
π is the ratio for Pi,
<u>In this case we will use:</u>
3.14 instead of π
d = 26.5 mm
<u>Plug in the known values. </u>
C=(3.14)(26.5) = 83.21 mm</span></span>
My mistake, answer must be put in y=mx+b. x+2y=0, you'd want to get y by itself, subtract x and divide by 2y, to get y by its lonely. The slope would be -1/2, the correct answer is A
Answer:
13
Step-by-step explanation:
(11x - 15) + (5x - 13) = 180 (Since a straight line = 180°)
11x + 5x - 15 - 13 = 180 (Combine like terms)
16x - 28 = 180 (Simplify)
16x - 28 + 28 = 180 + 28 (Add 28 to both sides)
16x = 208 (Simplify)
16x ÷ 16 = 208 ÷ 16 (Divide both sides by 16)
x = 13 (Simplify)
The answer is A because the slope is 25 and y intercept is 100.
1) 0.5^3+0.3^3=
0.5^3=0.125
0.3^3=0.027
0.125+0.027=0.152
2)Let X be the number:
X*7=6*50
7X=300
X=42.857
3) If it takes 3 identical pumps to fill a pool, one pump will take 8*3=24 hours to fill the pool. If you have 4 pumps, it will quadrupal the speed, making it take 24/4=6 hours.
Hope I helped!
