2 answers:

5 0

0.75 as a fraction is 3/4, and it’s already in the simplest form because the numerator (3), can’t be split. Think of it as three quarters, each quarter is 25 cents, and there are three of them, so that is 75 cents, and then let’s say you are counting how many quarters you have, to get a dollar, to get a dollar, you need 4 quarters, but you only have three so it makes it 3 quarters out of 4 (3/4). Hope this helps :)

The total cost of renting a popcorn machine for 6 hours is $48. What equation can be used to model the total cost y for renting

scoray [572]

Answer:

$y=8x$

Step-by-step explanation:

Let

y ----> the total cost for renting the popcorn machine

x ----> the time in hours

we know that

The total cost of renting a popcorn machine for 6 hours is $48

using proportion

Find out the total cost for renting the popcorn machine for x hours

$\frac{48}{6}=\frac{y}{x}\\\\y=(48x)/6\\\\y=8x$

Is a linear direct variation

The constant of proportionality or slope is equal to

$k=8\frac{\$}{h}$

That means ----> the total cost is $8 per hour

mr Goodwill [35]

Answer:

Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.

Step-by-step explanation:

Step 1: Factor

256x^4y^2−y^2

y^2(256x^4 - 1)

y^2(16x^2 - 1)(16x^2 + 1)

y^2(4x + 1)(4x - 1)(16x^2 + 1)

Answer: Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.

ikadub [295]

Answer: The least number of minutes that he has used his phone in a month is 1248

Step-by-step explanation:

Let m represent the number of minutes that he used his phone in a month.

For his phone service, Michael pays a monthly fee of $16, and he pays an additional $0.04 per minute if use. This means that if he used m minutes in a month, the total cost would be

16 + 0.04m

The least he has been charged in a month is $69.52. This means that

16 + 0.04m ≥ 65.92

0.04m ≥ 65.92 - 16

0.04m ≥ 49.92

m ≥ 49.92/0.04

m ≥ 1248 minutes

pashok25 [27]

Answer:399

Step-by-step explanation:

Given

baseball consist of Nine innings and there are 9 different Positions in baseball thus there are total of 9! ways in which a line can be formed

but in a single game there are 9 innings so there are $\frac{9!}{9}=8!$

and there are 101 games in single season so total no of season a team can play without repeating the same line-up

$\frac{8!}{101}=399.20\approx 399$

so a team can play a total of 399 season with different line up in every game.
