Answer:

301.44 cubic units

Step-by-step explanation:

$volume \: of \: cone \\ \\ = \frac{1}{3}\pi {r}^{2} h \\ \\ = \frac{1}{3} \times 3.14 \times {(6)}^{2} \times 8 \\ \\ = \frac{1}{3} \times 3.14 \times 36 \times 8 \\ \\ = 3.14 \times 12 \times 8 \\ \\ = 301.44 \: {units}^{3} \\ \\ \red{ \bold{volume \: of \: cone = 301.44 \: {units}^{3}}}$

Suppose you have 20 coins that total $4.some coins are nickles and sime are quarters .which of the following pairs of equations

Monica [59]

So 1 nickle=5 cents
1 quarter=25 sents

q=number of quarters
n=number of nickles so

total is
q+n=20
5n+25q=400 (since 100 cents=1 dollar and 4 dollares=400 cents)

SO THE 2 EQUATIONS WOULD BE
n+q=20
5n+25q=400

so q+n=20
subtract q from both sides
n=20-q
subsitute 20-q for n in the second equation
5(20-q)+25q=400
distribute
100-5q+25q=400
add like terms
100+20q=400
subtract 100 from both sides
20q=300
divide both sides by 20
q=15

thhere are 15 quarters

subsitute 15 for q in first equation

15+n=20
subtract 15 from both sides
n=5

5 nickles
15 quarters

Which function has an inverse that is also a function?

Vlad [161]

keeping in mind that a function does not have any X-Repeats, that is, the 1st coordinate in every pair never repeats, well, in this case, all of them have no X-repeats, that means all of them are functions. However, only one-to-one functions have an inverse that is also a function.

A one-to-one function is one that has no X-repeats as well as no Y-repeats, so each pair in the set has no coordinate repeats, Check the picture below.

What is the quotient? 212,960 - 1000 o 2.1296 21.296 212.96 0 2129.6

Nonamiya [84]

The quotient is 212.96.

Solution:

Given expression is $\frac{212,960}{1000}$ .

Divide the given expression to find the quotient.

Decimal rule when numerator is divided by 10, 100, 1000, 10000 etc..

If you have one zero in the divisor (10), then the decimal point will move 1 place to the left of the last digit.
If you have two zeros in the divisor (100), then the decimal point will move 2 place to the left of the last digit.
If you have three zeros in the divisor (1000), then the decimal point will move 3 place to the left of the last digit.

$$212960\div1000=\frac{212960}{1000}$

Here, we have 3 zeros in the denominator.

So, the decimal point is move 3 digit to the left of the last digit.

$$212960\div1000=212.96$

So, option C is the right answer.

Hence the quotient is 212.96.
