If it says 3×8 its like saying 8+8+8=21.
It's just a faster way of adding.
Anything multiplied by 0 is 0.
Anything multiplied by 10 just add a 0 to the end of the number example 10×2=20.
Answer:
x - 8 ≤ 4
+8 +8 Add eight to both sides of the equation.
X≤12
2x + 3 > 9
-3 -3 Subtract three from both sides
2x>6 Divide both sides by 2
x>3
Hope this helps!
Have an amazing day/night!
3 cakes in 2.5 hours
Divide 7.5 (hours you are solving for) by 2.5 (known hours for 3 cakes)
7.5/2.5=3
Multiply that answer, 3 * 3= approximately 9 cakes in 7.5 hours
You would have to transform the fractions to decimals by dividing. For the first one, if you divide 4 by 5 you get .8. To transform a decimal to percent you move the decimal place 2 times to the right or multiply by 100 (They both would give you the same thing)
Answer:
C. 434π
Step-by-step explanation:
Given:
Radius (r) = 7 in.
Height (h) = 24 in.
Required:
Surface area of the cylinder
Solution:
S.A = 2πrh + 2πr²
Plug in the values
S.A = 2*π*7*24 + 2*π*7²
S.A = 336π + 98π
S.A = 434π
