How many perfect cubes divide evenly into 13824?

1 answer:

3 0

Since that number is a perfect cube it's self, you just need to look at its cube root's factors, and each of those when cubed bust still evenly divided your number. alternatively you could just factorise your number into primes and any factor that turns up at least thrice, when cubed will divide your number evenly

A printer takes 30 minutes to print a banner and a poster. I will take 50 minutes to print a banner and three posters. How long

qwelly [4]

Answer:

It takes the printer 20 minutes to print a banner

Step-by-step explanation:

Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.

So we can write the following two equations involving the total amount of time that takes to print in the two cases:

$b+p=30\\b+3p=50$

We can solve for the unknown "p" by subtracting term by term in the equation set above:

$b+3p=50\\b+p=30\\\\b-b+3p-p=50-30\\2p=20\\p=10$

So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:

$b+p=30\\b+10=30\\b=20$

So, it takes 20 minutes to print a banner.

A parking space is 20 feet long. A pickup truck is 6 yards long. How many inches longer is the parking space than the truck

masya89 [10]

1 yard = 3 feet.

Multiply the length of the truck by 3 to get total feet:

6 x 3 = 18 feet.

Subtract the length of the truck from the length of the parking space:

20 - 18 = 2 feet

1 foot = 12 inches.

Multiply 2 feet by 12:

2 x 12 = 24 inches longer.

Is x+3=-5y in standard form?

skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is $Ax+By=C$ with the terms containing x and y on the left side of the equation and a number on the right side.

$x+3=-5y$

Subtract 3 from both sides.

$x=-5y-3$

Add 5y.

$x+5y=-3$
