Answer:

0.28 and 4.48

Step-by-step explanation:

c) You have to find the number by which the numbers in the list get multiplied.

If you divide the third number 1.12 by the first 0.07, you get 16. To get from 0.07 to 1.12, the 0.07 was multiplied twice by this number. 16=4*4, so the multiplier is 4.

Now it is possible to calculate the whole series:

0.07 * 4 = 0.28

0.28 * 4 = 1.12

1.12 * 4 = 4.48

4.48 * 4 = 17.92

d) divide the second by the first number:

\frac {1}{1\frac{1}{10}} = \frac{1}{\frac{11}{10}} = \frac{10}{11}

So work with factor 10/11 to calculate the series:

11/10, 1, 10/11, 100/121, 1000/1333, ...

g) Divide 7/12 by 2/3 to find 7/8. So the number preceding 2/3 is (2/3) / (7/8) = 16/21 and the numbers after 7/12 are:

(7/12) * (7/8) = 49/96

and

(49/96) * (7/8) = 343/768

A paint can has a radius of 4 inches and a height of 15 inches. What is the volume of the paint can? Round to the nearest tenth.
Vlad1618 [11]
R=4 in
h=15 in

The paint can is a cylinder. The volume of the cylinder is: V=S×h (S stands for the area of the base, h is for height).
The area of our cylinder's base is a circle, so:
S=πr²=4²×π=16π≈50.24 (in²)
Thus, the volume is:
V≈50.24×15≈753.6 (in³)

H=7+44t-16^2
zalisa [80]

Answer:

When t=2.1753 & t=.5746 , h=27

Don't worry, I got you. Also, my calculator does too.

We set h equal to 27, because we want the height to be 27 when we solve for t.

That leaves us with:

27 = 7 + 44t - 16t^2

Simplify like terms,

20 = 44t - 16t^2

Move 20 onto the right side, so we can use quadratic equation

44t - 16t^2 - 20 = 0 --> -16t^2 + 44t - 20

Using quadratic, you get

t=2.1753 & t=.5746

<u>poster confirmed : "It’s t=2.18 and t=0.57"</u>
