Answer:

4, see below :)

Step-by-step explanation:

We can rewrite the equation into:

3.5 + 2 - 1.5

First we add 3.5 and 2

3 and 2 are in the ones place so:

5, and then you added the .5

5.5

Then:

5.5 - 1.5

First we subtract the tenths place so:

.5 - .5 = 0

Then the ones:

5 - 1 = 4

The volume in cubic centimeters of a sphere whose diameter is 6 centimes is ?

aivan3 [116]

Answer:

Volume of the sphere is 36π (or) 113.097 cubic centimetre.

Step-by-step explanation:

$given \\ diameter \: of \: sphere = 6 \: cm \\ radius \: of \: sphere \: = \frac{diameter}{2} \\ radius \: = \frac{6}{2} \\ radius \: (r) = \: 3 \: cm \\ volume \: of \: sphere \: = \frac{4}{3} \pi \: {r}^{3} \\ here \: r \: = 3 \: cm \\ on \: substituting \: r \: = 3 \: \: in \: formula \\ volume \: of \: sphere \: = \frac{4}{3} \pi \: {3}^{3} \\ \: \: = \frac{4}{3} \pi \: 27 \\ \: = \: 4 \pi \times 9 \\ \: \: = 36\pi \\ \: \: = 113.097 \: {cm}^{3}$

PLEASE HELP ME Use the function below to find f(2). f(x) = 1/3 x 4^x

Anna71 [15]

f(2) This means that x is 2, so you plug in 2 for x in the equation

$f(x)=\frac{1}{3} (4^x)$

$f(2)=\frac{1}{3}(4^2)$

$f(2)=\frac{1}{3} (16)$

$f(2)=\frac{16}{3}$

Your answer is D

Expression where the solution is 19

MA_775_DIABLO [31]

We want something that equals 19 right? Anything can work here such as
10+9=19 <---we have our outcome as 19
If you want something more complex
1(10)+10-1=?
When you solve that it equals 19! :)

Given the equation 6/x=3/k+2, and the constraints x ≠ 0 and k ≠-2, what is x in terms of k?

Veronika [31]

Answer:

A) 2k+4

Step-by-step explanation:

To solve for terms of x, we need to. she sure that x is on its own side while every other term is on the other side.

To start, we will cross multiply. If we have a/b=c/d, then ad=bc

We can perform the same calculation here,

6/x=3/(k+2)

6(k+2)=3x

Divide both sides by 3

2(k+2)=x

x=2k+4

How would I solve this? Because I don't understand it at all.

Mandarinka [93]

Answer:

v= s/t = sqrt(360^2+480^2) x 0.3048/0.5 = 365.76(m/s)

Step-by-step explanation:

s =sqrt(360^2+480^2)

s-ft-to-m = s*0.3048

t = 0.5
