Mathematics

Answer:

D) 81x²y¹⁰

Step-by-step explanation:

(9xy⁵)²

Because all of 9xy⁵ are in the parentheses, each component is raised to the 2nd degree.

(9)² = 81

(x)² = x²

(y⁵)² = y¹⁰ -- When you raise an exponent to another exponent, you multiply the exponents.

Now combine the components.

D) 81x²y¹⁰

vichka [17]

You need to show the line put. If you show the line plot i may be able to answer. But F.Y.I. you are going to probably using proportions or need to multiply the hours she jogs in one day by the 5 days. Hope this helps.

Jason had three more than four times the amount of money that Jeff has. Together they have $72. How much money does each person

adelina 88 [10]

Answer:

Jason has $58.20 and Jeff has $13.80.

Step-by-step explanation:

Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.

We know that together they have $72. So, we can write the following equation:

$x+y=72$

We know that Jason has three <em>more</em> than four <em>times</em> the amount of money Jeff has. So:

$x=3+4y$

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

$(3+4y)+y=72$

Combine like terms:

$5y+3=72$

Subtract 3 from both sides:

$5y=69$

Divide both sides by 5:

$y=69/5=\$13.80$

So, Jeff has $13.80

We know that Jason has three more than four times the amount of money Jeff has.

Therefore, Jason has:

$x=13.8(4)+3$

Multiply and add:

$x=\$58.20$

So, Jason has $58.20 and Jeff has $13.80.

And we're done!

brilliants [131]

$\huge \boxed{Answer}$

there are two containers in four parts has to be filled in each, therefore, the fraction greater than one will be =

total number of part stobe filler in container

_________________________________________

number of parts in each container

= 8/4

the whole number greater than one will be = 2

hence, the whole number and a fraction greater than one to name the part filled is 2 and 8/4

What is 1000x4680. Calculators are acceptable, that's why it's 38 points.

salantis [7]

Answer:

4,680,000

Step-by-step explanation:

Whenever multiplying by 10s, 100s or 1000s, just add the 0s to the answer.

So 4680 plus three 0s would be 4,680,000
