It takes the Sun about 2.3x10^8 years to orbit the center of the Milky Way. It takes Pluto about 2.5 times 10 squared years to orbit the Sun. How many times does Pluto orbit the Sun while the Sun completes one orbit around the Milky Way?

Answers

if equals c 10 five dndsndndn

It takes the Pluto about 14.375 x 10¹⁰ years to orbit the Sun while the Sun completes one orbit around the Milky Way

What is multiplication?

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

It takes the Sun about 2.3x10⁸ years to orbit the center of the Milky Way.

It takes Pluto about 2.5 times 10 squared years to orbit the Sun.

Pluto orbits the Sun while the Sun completes one orbit around the Milky Way,

= 2.3 x 10⁸ x (2.5 x 10)²

= 14.375 x 10¹⁰

Therefore, the required time is 14.375 x 10¹⁰ years.

Money was placed in a savings account and earned 3/4 % interest paid annually. Samantha, Tony and Anuyia each wrote an equation to show the amount of money in the account after one year with a balance of M dollars. T represents the total amount of money in the account.

Samantha’s Equation: T = 1.075M

Tony’s Equation: T = M + 0.0075M

Anuyia’s Equation: T = M(1 + 0.0075M)

Since none of the equations were written the same, they decided to see if their equations would give the same answers by using a $75 balance. Solve this problem using each student’s equation.

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.

0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.

Answers

Answer: 1.08j

Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right

1.08j

I’m not 100% sure tho

The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

What is Percentage?

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.

Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket

= j + 0.08j

= 1.08j

Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

Find the value of x:

Answers

Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x

Answer:

(10x+1)°=(12x-5)°. [vertically opposite angle]

1+5=12x-10x

6= 2x

3=x

therefore,x=3

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!

Answers

Answer:

A = (1/2)Pa = Pa/2

You can multiply both sides by 2 to eliminate the fraction on the right side:

2A = 2(Pa/2) = Pa

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

Rewriting:

P = 2A/a

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.
