Joel made egg sandwiches and tuna sandwiches in the rAtio do 2:3. He then made 15 tuna sandwiches and the rating changed to 1:3. How many sandwiches did Joel make in all

Answers

Answer 1

Answer: He made 45 sandwiches.
The ratio of tuna sandwiches never changed, therefore he made the same amount (15) both times.
2/3 of 15 is 10.
1/3 of 15 is 5.
5 + 10 + 15 + 15 = 45.
Hope that helped =)

Answer 2

Answer:

Step-by-step explanation:

15 divided by 3 = 5

5 x 2 = 10

10 + 15 + 15 = 40

The answer is 40

Park Rangers are counting the deer population in a state park. They divide the park into sections that are each 324 square feet. The width of each section is 12 feet. What is the perimeter of each section of the park?

Answers

The problem is literally telling you the answer. The perimeter would be 324. It is just giving you extra information in the problem that is probably making you confused.

In order to find the perimeter, you have to find the length. It says the area is 324 suare feet, so you must divide 324 by 12 to find length. Once you have length, you have a rectangle. Perimeter is 2 times the length plus 2 times the width, so subsequently the answer is 78 feet.

Cual es la simplificacion de 66/81

Answers

Answer:

Hence the simplification of $(66)/(81)$ is $(22)/(27)$

Step-by-step explanation:

" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter),

for example: Simplification of a fraction to an irreducible fraction ".

Here we are given a fraction as:

$(66)/(81)$

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.

As 66=3×22 and 81=3×27

Hence $(66)/(81)=(3*22)/(3*27)=(22)/(27)$

Hence the simplification of $(66)/(81)$ is $(22)/(27)$

A soccer team played 32 games. If they won 25% of them, how many games did they win?

Answers

X/32= 25/100
100x, 800
800 divided by 100= 8
X = 8 games

25% is the same as 1/4.
1/4 is the same as ÷ 4
32 ÷ 4 =
16 ÷ 2 =
8

If a soccer team won 25% of their 32 games, they won 8 of them.
