Someone cut a whole pizza into 3 equal parts she gave her four children the same amount of one of the sections what part of the whole pizza did she give each one of her children?

Answers

Answer: 1/12 of the whole pizza

Step-by-step explanation:

Someone cut a whole pizza into 3 pieces.

This means that the pizza was cut into 1/3 slices each.

She then gave her 4 children one of these sections to share equally.

The part each child got is:

= 1/3 ÷ 4

= 1/3 * 1/4

= 1/12 of the whole pizza

Note: When dividing fractions, you can multiply the first fraction by the inverse of the second fraction to find your answer.

Maritza counted 40 green cars and 20 silver cars in the parking lot. If the number of green cars stays the same, how many more silver cars would need to be added so the ratio of green cars to silver cars is 1 to 3?

Answers

Answer:

100 more silver cars

Step-by-step explanation:

OK so first I made a fraction being 40/20 so green cars over silver cars. Then i multiplied the fraction by 1/6, which gave me 40/120 and to make sure that it was a proper fraction. I found a common denominator. I found that the common denominator was 40. So divided both sides by 40. (40/40=1) (120/40=3) causing the answer to be 100 silver cars because you had to have 120 silver cars and 40 green cars to have a 1 to 3 ratio

Hope this help

Answer:

[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]

Step-by-step explanation:

Given in the question:

a) A family paid $96 for 4 pool passes and 2 gym memberships.

b) Later that day, an individual bought pool passes for herself and 2 of her friends, and 1 gym membership for her. She paid $60.

Let's write the system of equations for each purchase  that happened in the scenario.

Let,

P=Price of each pool passes

G= Price of each gym membership

We get,

a) A family paid $96 for 4 pool passes and 2 gym memberships:

[tex]4P+2G=96[/tex]

b) Later that day, an individual bought pool passes for herself and 2 of her friends , and 1 gym membership for her. She paid $60:

[tex]3P+1G=60[/tex]

Therefore, the equations generated in the scenario were:

[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]

Where,

P=Price of each pool passes

G= Price of each gym membership

Aditi has invested ₹ 1,00,000 for 2 years and has received ₹ 10,000 as interest. What is the rate percent?

Answers

Answer: 5%

Step-by-step explanation:

Aditi invested 100,000 Rupees and after 2 years had 10,000 Rupees in interest.

Interest percent is therefore:

= Interest / Principal

= 10,000/100,000

= 10%

This is for 2 years though so you need to find for a year:

The area of a rectangular knitted blanket is 10x squared minus 11x minus 6. What are the possible dimensions of the​ blanket? Use factoring.

Answers

Answer:

Dimensions of rectangle are [tex](5x+2)\:and\: (2x-3)\\[/tex]

Step-by-step explanation:

Area of rectangular knitted blanket = [tex]10x^2-11x-6[/tex]

We need to find the dimensions of blanket.

If we need to find the dimensions, we need to find the factors of area.

Factoring:  [tex]10x^2-11x-6[/tex]

We will break the middle them -11x

Adding 4x-15x we get -11xMultiplying 4x and -15x we get -60x^2 (Product of -6 and 10x^2)

Now, finding factors

[tex]10x^2-11x-6\\10x^2+4x-15x-6\\2x(5+2)-3(5x+2)\\(5x+2)(2x-3)\\[/tex]

So, factors of [tex]10x^2-11x-6\\[/tex] are [tex](5x+2)(2x-3)\\[/tex]

So, dimensions of rectangle are [tex](5x+2)\:and\: (2x-3)\\[/tex]

Two angles are supplementary. The measure of one angle is 10 less than twice the measure of the other angle. Find the measures of the angles.​

Answers

Step-by-step explanation:

Supplementry means which add up to 180°

Now, let's take one of them as x

And the other as x - 10

Now let's add : x + (x - 10) = 180°

2x - 10 = 180°

2x = 180 + 10

2x = 190

x = 190/2

x = 95

X = 95

x - 10 = 95 - 10

So, = 85

The 2 numbers are 95, and 85

Lets check!

95 + 85 = 180!

So therefore they are supplementry so it's right!
