Answer:
x = 4.5
Step-by-step explanation:
a^2 + b^2= = c^2
4^2 + 2^ = c^2
16 + 4 = c^2
20 = c^2 --> find square root of 20 and round to nearest tenth*
4.47 = c
round up to 4.5

Answer:
more than 9 hours
Step-by-step explanation:
Goran's net earnings for h hours work will be ...
7h -5 . . . . hourly pay less equipment fees
He wants this amount to be more than $58:
7h --5 > 58
7h > 63 . . . . . add 5
h > 9 . . . . . . divide by 7
Goran could trim trees for more than 9 hours.
A9=A1+(n-1)
-2.75+(8*0.25)
-2.75+2=-0.75
Answer:
0.875
Step-by-step explanation:
to convert the fraction 7/8 to decimal
therefore 7 divided 8 = 0.875
Step-by-step explanation:
remember. the radius is always half the diameter.
volume of a cylinder
pi × r² × height
pi×7.5²×48 = pi×56.25×48 = 8,482.300165... in³
volume of a sphere
4/3 × pi × r³
and that volume should be the same as the cylinder. so,
4/3 × pi × r³ = pi×56.25×48
4/3 × r³ = 56.25 × 48
1/3 × r³ = 56.25 × 12
r³ = 56.25 × 36 = 7.5² × 6² = (7.5×6)² = 45² = 2025
![r = \sqrt[3]{2025}](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%5B3%5D%7B2025%7D%20)
which would be 12.65148998... in.
