The amount of pizza that Ruby and Angie ate in all for this considered situation is given by: Option A: 8/15

How to add two fractions?

Let we have to add two fractions as:

$(a_1)/(b_1) + (a_2)/(b_2)$

Then we will find LowestCommon Multiple (LCM) of $b_1$ and $b_2$ . That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the finalresult of addition.

So, we're specified that:

Ruby ate 1/3 of a pizza
Angie ate 1/5 of the pizza

These 1/3 and 1/5 are parts of pizza.

If we add those parts which is eaten, we will get the total part of the pizza eaten.

Thus, we get:

Total part of the pizza eaten = (1/3 + 1/5) of a pizza.

The least common multiple of 3 and 5 is 15, because:

$3,6,9,12,15\n5,10,15$

(see the multiples of 3 and 5. The first common number as both's multiple is the least number which is multiple of both, and is 15).

Thus, we get:

$(1)/(3) + (1)/(5) = (1 * 5 + 1 * 3)/(15) = (8)/(15)$

Thus, the amount of pizza that Ruby and Angie ate in all for this considered situation is given by: Option A: 8/15

Answer 2

Answer: A = 8/15 of the pizza
Well, 1/3 + 1/5 = (5+3)/ 15 = 8/15

identify a two-digit dividend that will result in a quotient with a remainder of 1 when the divisor is 4.

Answers

Answer:

Number will be of the form a=4q+1

Example: 13,17,21,......

Step-by-step explanation:

We have been given that we have remainder 1, divisor 4

So, we can take many numbers which is 1 greater than the multiple of 4.

the numbers will be of the type:

a=4q+1

We can use Euclidean division algorithm

a=bq+r

Here, b is 4, q we will consider we will consider q>=3

So, let q=3

We will get

a=4(3)+1=13

Put q=4

a=4(4)+1=17

There are many numbers.

The answer is 17 because 17 divided by 4 equals 16 with the remainder of 1

How do you find the radius of a sphere when you know the area

Answers

Since the area formula is pi times radius to the second power, then just plug in the things you know. for ex: The area is 314, then work backwards and divide 314 by pi which equals 100 then unsquare it which is 10 because 10*10=100. So the radius is 10

What is another name for a regular quadrilateral

Answers

A square is an example of a regular quadrilateral.

a square a is a type of regular quadrilateral so is a rectangle.

A rectangle has a length six less than three times the width.If the perimeter is 28 units find the width and length

Answers

Answer:

Width = 5 and Length = 9 units.

Step-by-step explanation:

Let the width be W, then the length L = 3W - 6.

Perimeter = 2W + 2L = 2W + 2(3W - 6) = 28.

2W + 6W - 12 = 28

8W = 40

W = 5 units.

Therefore L = 3(5) - 6 = 9 units.

Step-by-step explanation:

Length:

l = 3w - 6

Perimeter:

P = 2l + 2w = 2(3w - 6) + 2w = 8w - 12 = 28 --> w = 5

l = 3*5 - 6 = 9

Liam rode his bike to the store every day. It took him 45 minutes to get to school and 45 minutes to get home. If he rode for 3 weeks, how many minutes will he ride in all?

Answers

Answer:

1,890 minuts

Step-by-step explanation:

3 weeks = 7 days x 3 = 21 days

He rides his bike for "45 minutes to get to school and 45 minutes to get home" which is 90 minutes per day.

Therefore, in total, he rode for 21 days x 90 minutes per day = 1,890 minutes
