Answer:
1/6
Step-by-step explanation:
5/10(3/3)=15/30
2/6(5/5)=10/30
15/30 - 10/30= 5/30 = 1/6
Answer: 52.7856cm
Step-by-step explanation:
Circumference of a circle = 2πr
Note that radius = Diameter / 2 = 16.8/2 = 8.4cm
Circumference = 2πr
= 2 × 3.142 × 8.4
= 52.7856cm
Therefore, the circumference of the circle is 52.7856cm
Lynn mixes 39 pounds of water with 48 pounds of brick dust, so the mixture has a total weight of 39 + 48 = 87 pounds.
13 pounds are spilled during mixing, so she's left with 87 - 13 = 74 pounds to turn into bricks.
7 pounds are needed for 1 brick, so she can make 10 bricks because 7 • 10 = 70 and 7 • 11 = 77, and 70 < 74 < 77.
If she uses the mixture to make 10 bricks, she uses up 70 pounds of it, which leaves 4 pounds to be washed out.
Answer:
3x^2+5
Step-by-step explanation:
f(x) = 3x + 2 ; g(x) = x^2+ 1
(fºg)(x) = 3(x^2+ 1)+2
(fºg)(x) = 3x^2+3+2
(fºg)(x) = 3x^2+5
