Answer:

50 newspapers

Step-by-step explanation:

100 (total amount of newspapers) - 25 (amount Edward already sold) = 75 (amount of newspapers left)

75 (amount of newspapers left) ÷ 3 (Edward and his 2 friends) = 25 (equal amount each person delivered)

25 (amount Edward already sold) + 25 (amount Edward sold after his friends helped him) = 50 (amount of newspapers Edward sold in total)

Alex and Freddy collect stamps. The number of stamps in Alex’s collection to the number of stamps in Freddy’s collection is in t

vazorg [7]

Remark

The trick here is to realize that you have to find the number both have in order to find the difference. That means you take (effectively) 3/8 and 5/8 to find out how much each of them has. The 8 stands for the 136

Step One

Find the number of stamps Alex has. Remember his ratio is the smaller so he will have 3/8

Alex = 3/8 * 136

Alex = 408/8 = 51

Step 2

Find the number that Freddy has.

The total is 136

Formula

Freddy = Total - Alex

Freddy = 136 - 51

Freddy = 85

Check

Let us see if 5/8 * 136 = 85

5*136/8 = 680 / 8 = 85 So your answers are correct.

Difference

Difference = 85 - 51 = 34 which is how many more stamps Freddy has than Alex.

What is the quotient of 3/4 divided by 1/5? The quotient is 3 and ___________

Zanzabum

Answer:

The quotient is 3 and $\frac{3}{4}$ .

Step-by-step explanation:

To find the quotient of the division (which is just the solution, really), we have to solve the division itself:

$\frac{\frac{3}{4}}{\frac{1}{5}}$

$= \frac{3 \cdot 5}{1 \cdot 4}$

$= \frac{15}{4}$

Now that we know the quotient, we can look at the question itself to find it requires from us an answer with a whole number in it.

Therefore, we transform the fraction as thus:

$\frac{15}{4}$

$= 3 \frac{3}{4}$

Therefore, the final answer is 3 and $\frac{3}{4}$ .

Hope this helped!

Answer:

The perimeter of triangle is 30ft.

Step-by-step explanation:

First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :

${a}^{2} + {b}^{2} = {c}^{2}$

${a}^{2} = {c}^{2} - {b}^{2}$

$a = \sqrt{ {c}^{2} - {b}^{2} }$

Let b = 12,

Let c = 13,

$a = \sqrt{ {13}^{2} - 12 {?}^{2} }$

$a = \sqrt{25}$

$a = 5feet$

Next you have to find the perimeter of triangle by adding all the sides together :

$perimeter = 5 + 12 + 13$

$perimeter = 30feet$
