The answer would be 1. This is because if you do this equation for every row in the table it would always equal y. 1/2x (x divided by 2) would always equal 2 less than y. There is no unit rate in this problem because it is not proportional.

20 POINTS / WILL GIVE BRAINLIEST

padilas [110]

Answer: Total Volume = 15π + 18 π= 33π cubic mm

Step-by-step explanation:

What is the volume of the composite figure? Leave the answer in terms of π.

_33π mm3

We have a cone here conjoined to a semi-sphere.

Cone volume: C = (1/3)*(πr^2) * h

semi-sphere volume : V = (1/2)* (4/3) * (π * r^3)

r = 3 mm and h = 5mm

so C = (1/3)*(π (3)^2) * 5 = 15π cubic mm

V = (1/2)* (4/3) * (π * 3^3) = 18 π cubic mm

Total Volume = 15π + 18 π= 33π cubic mm

Answer:

$\large\boxed{a.\ 7200\pi\ mm^2}$

Step-by-step explanation:

The formula of a surface area of a cylinder:

$S.A.=2\pi r(r+H)$

r - radius

H - height

We have r = 40mm and H = 50mm. Substitute:

$S.A.=2\pi(40)(40+50)=80\pi(90)=7200\pi\ mm^2$

The winner of a 100 mile race drove his car to victory at a rate of 120.1229 mph. What was his time to the nearest thousandth of

Zigmanuir [339]

Answer:

$t=1.201\ \text{hour}$

Step-by-step explanation:

Given that,

Distance, d = 100 mile

Velocity of the winner, v = 120.1229 mph

We know that velocity of an object is equal to distance per unit time. Let t is the time. So,

$v=\dfrac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{120.1229}{100 }\\\\t=1.201229\ \text{hour}\\\\\text{Round to the nearest thousandth}\\\\t=1.201\ \text{hour}$

Hence, 1.201 hour is taken by the winner.
