-5/8 = 6.25

6.25n
Product: 0.4

0.4 divided by 6.25 = 0.064.

0.064 is the final answer.

1. Find the Least Common Multiple of these two monomials: See picture

gtnhenbr [62]

Answer:

The last choice is correct

$LCM=120a^4b^7c^5$

Step-by-step explanation:

Least Common Multiple (LCM)

To find the LCM we can follow this procedure:

List the prime factors of each monomial.

Multiply each factor the greatest number of times it occurs in either factor.

We have two monomials:

$12a^4b^2c^5$

$40a^3b^7c^1$

The prime factors of the first monomial are:

$2^2,3,a^4,b^2,c^5$

The prime factors of the second monomial are:

$2^3,5,a^3b^7c^1$

LCM = Multiply $2^3*3*5*a^4*b^7*c^5$

These are all the factors the greatest number of times they occur.

Operating:

$LCM=8*15*a^4*b^7*c^5$

$\boxed{LCM=120a^4b^7c^5}$

The last choice is correct

If your salving for n it would be n=0.75
If your salving by factoring it is 3/4

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t) = 60t - 16t^2 . What i

svetoff [14.1K]

Answer:

56.25 feet.

Step-by-step explanation:

h(t) = 60t - 16t^2

Differentiating to find the velocity:

v(t) = 60 -32t

This equals zero when the ball reaches its maximum height, so

60-32t = 0

t = 60/32 = 1.875 seconds

So the maximum height is h(1.875)

= 60* 1.875 - 16(1.875)^2

= 56.25 feet.

Please help me make a word problem for water bottles. (See picture below)

Alona [7]

1. "Kevin has a 15% off coupon for buying water bottles at Walmart.

One water bottle is usually $2.00. How much did Kevin pay with his coupon?"

2. $1.70.

3. The answer is $1.70, because $2.00 * 0.15 = 30 cents, which is how much the coupon is worth. The sale price is the original amount minus the coupon's monetary value (which is $2.00 - $0.30 = $1.70).

4. I'll leave that part to you lol
