Using a system of equations, the amount of solution a and b required to make the required gallons of the solution are 29.41 and 20.59 respectively.

Let :

a + b = 50 - - - - (1)

0.24a + 0.41b = 50 × 0.31

0.24a + 0.41b = 15.5 - - - - (2)

From (1) :

a = 50 - b - - - - (3)

Substituting (3) into (2)

0.24(50 - b) + 0.41b = 15.5

12 - 0.24b + 0.41b = 15.5

0.17b = 15.5 - 12

0.17b = 3.5

b = 20.588

From (3) :

a = 50 - 20.588

a = 29.412

Therefore, about 29.41 gallons of solution a and 20.59 gallons of solution b is required.

Answer:

438 miles

Step-by-step explanation:

You need to find 120% of 365 because 120% would just be 100% (the starting 365 miles) + the 20% miles on the third day. 120% of 365 would be 438 miles.

Step-by-step explanation:

Reflections are mirror images over what they are being reflected off.

Think of your own reflection in the mirror. It's not exact, like pictures is it? You could also think of it as folding a piece of paper that has wet paint on it in half. The painted image transfers to the other side of the paper, but it's not exactly the same as the original.

I don't know how exactly to explain it, but that is how I think of it.

Answer:

42

Step-by-step explanation:

300 is a multiple of 100. On the graph we can see that 14% of the students favor fishing. 14% of 100 is just 14. Once we have that, we can just multiply by 3, since 3 × 100 = 300:

3 × 14 = 42.

The number of campers supporting fishing will be 42

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the graph shows the favorite activities of campers at a summer camp. Suppose there are 300 campers at the camp. 14% of campers are supporting fishing.

The number of campers supporting fishing will be:-

Number = 300 x 14%

Number = ( 300 x 14 ) / 100

Number = 3 x 14

Number = 42

Therefore, the number of campers supporting fishing will be 42.

Answer:

2 [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

First, we will turn 5 2/5 into an improper fraction:

5 * 5 = 25 + 2 = 27/5

So they worked for 27/5 days.

We want to divide the days worked by the distance to get the unit rate of distance per day:

[tex]\frac{12}{\frac{27}{5} } = \frac{12}{1} * \frac{5}{27}=\frac{60}{27}=\frac{20}{9}[/tex]

So our answer is 2 [tex]\frac{2}{9}[/tex]

Answer:

≈3.14

Step-by-step explanation:

The formula for finding the area of a circle is:

π·r²

π=approximately 3.14(pi)

r=radius

If you follow this formula,

you would multiply 3.14 by 2², which is basically 2x2.

2x2=4   3.14x4=12.56

But since pi is an irrational number that goes on forever, you usually round pi to the hundredths place, which would be 3.14. But since you're finding the area of 1/4 circle, you need to divide the answer by 4. 12.56/4=3.14, so the answer is about 3.14.

Answer:

Step-by-step explanation:

We'll compare it with the study of sets, the most noticeable operation of which is:

where,

n(A ∪ B) is the Union Set, i. e, the set that contains all the elements

n(A) is a subset of the Union Set

n(B) is another subset of the Union Set, and

n(A ∩ B) is the Intersection Set ,i.e, the set contains common elements from both A and B sets.

Let set A contains the students who play basketball and set B, the students who play Volleyball.

10 students play both of them, i. e.,

Using the above operation:

=> n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

=> n(A ∪ B) = 25 + 20 - 10

=> n(A ∪ B) = 35

The total number of students in the class

= students into the given sports + students who don't play any of them

The students who play neither = 60 - 35

= 25

Answer:

35

Step-by-step explanation:

It is easiest to find the full number if you find just 1/7 first. We know that we have 3/7 in total, so divide the number, 15, by 3 to get 1/7 of the total number. This gives 5. Therefore, 5 is 1/7 of the total. Thus, to find the total, simply multiply 5 by 7. This gives the total 7/7, 35.
