Answer:

You don't agree because the equation is y = 3x and f(x) = 3x

Step-by-step explanation:

You would not agree because y = 3x would essentially be a line starting at 0 and going up by 3 whereas

Y = 3(x+8) the graph would start at (0, 24) first point and the second would be (-8,24)

David made a scale drawing of a mural he is going to paint. He used a scale of 1 cm=4ft. If the actual mural will be 16 feet lon
VikaD [51]

Answer:

4 cm

Step-by-step explanation:

we know that

The scale drawing is

\frac{1}{4}\ \frac{cm}{ft}

That means ----> 1 cm in the drawing represent 4 ft in the mural

so

To find out the dimensions in the drawing, multiply the actual dimension by the scale drawing factor

so

(16\ ft)(\frac{1}{4}\ \frac{cm}{ft})=4\ cm

The volume of a sphere is 3,000 m^3. What is the surface area of the sphere to the nearest square meter?
vovangra [49]

Answer:

C

Step-by-step explanation:

V=4 /3πr3

3000=1 1/3*3.14*r*r*r

3000=4.18666667*r*r*r

716.560509=r^{3}

Cube root the number

8.94851471456=r

TSA=4\pir^{2}

TSA=4*3.14*8.94851471456*8.94851471456

TSA=1006.26

Since we used different numbers for pi and I rounded our answer will be different but the answer is C

An oil company fills 1 over 12 of a tank in 1 over 3 hour. At this rate, which expression can be used to determine how long will
Leto [7]
Don't let fractions fool you.

\frac{1}{12} of a tank in \frac{1}{3} an hour is equal to:
1/12 of a tank in 20 minutes.

Thus we know in an hour, an oil company can fill 3/12 of a tank (60 minutes in an hour).

3 x 4 = 12, and 12/12 = 1(a whole tank), so we multiply 1 (hour) by 4.

Our answer is that it takes 4 hours to fill a tank.
