A cone has a radius of 3 units and a height of 4 units.

Alika [10]

Answer:

1. V = 37.7

2. V =603.19

Step-by-step explanation:

1. V = (3.14)×3^2 4/3

V =37.7

2. V=(3.14)×(3×4)^2 4/3

V = (3.14)×12^2 4/3

V = 603.19

Administrators at a local high school are organizing desks in the cafeteria for the junior students to use while taking a practi

ICE Princess25 [194]

Answer:

correct choice is B

Step-by-step explanation:

If d represents the number of desks in each row and the administrators want there to be 13 less rows than the number d of desks in each row, then the number of rows is d-13.

The total number of desks in all rows is

$d\cdot (d-13)=d^2-13d.$

Due to space limitations, there should be fewer than 264 students in the cafeteria. Therefore,

$d^2-13d$

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.

KengaRu [80]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the 8 expressions are not given.

The general explanation is as follows

As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.

Then you categorize each result, depending on if it equals $5^{10}$ or not

Take for instance:

$5^5 * 5^5$

Using law of indices:

$5^5 * 5^5 = 5^{5+5$

$5^5 * 5^5 = 5^{10$ ---- equivalent

$\frac{5^5 + 5^5}{2 * 5^{-5}}$

Factorize the numerator

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1 + 1)}{2 * 5^{-5}}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}$

Cancel out 2

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}$

Apply law of indices

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10$ ---equivalent

$125 * 78125$

Express as exponent

$125 * 78125 = 5^3 * 5^7$

Apply law of indices

$125 * 78125 = 5^{3+7$

$125 * 78125 = 5^{10$ ---- equivalent

$5^3 + 5^7$

Solve exponents

$5^3 + 5^7 = 125 + 78125$

$5^3 + 5^7 = 78250$ ---- not equivalent
