The ratio of boys to girls in a choir is 3 to 7 there are 35 girls in the choir how many members are in the choir

Answers

Answer:

50

Step-by-step explanation:

35/7= 5

5*10=50

Answer:

50 people in the choir

Step-by-step explanation:

we can solve for x, assuming x is the value in which 1 is on the ratio. 7x=35, so the value of x would be 5. Next, we must multiply x by 3 since that is what the ratio states. If we do this, we will get 5*3, or 15. Therefore, there are 15 boys in the choir. Last, we have to add 15+35 to get the total number of people in the choir. There are 50 people in the choir.

Hope this helps! :)

A painter needs to paint the bottom of a circular pool. The pool has a radius of 30 feet. A store sells 5-gallon cans of paint. Five gallon of paint covers 1500 square feet. What is the smallest number of 5-gallon cans the painter must buy to cover the bottom of the pool?

Answers

Answer:

2 cans

Step-by-step explanation:

Given that :

Radius of pool = 30 feets

Using the relation for the Area of a circle :

Area = pi*r^2

Thus,

Area of pool = 3.14 * 30^2

Area of pool = 3.14 * 900 = 2826feet²

Paints are sold in cans of 5 gallon

5 gallon of paint = 1500 feet²

Least number of 5 gallon can required :

2826 feet² / 1500 feet² = 1.884 cans

Hence,

Least number of 5 gallon can required = 2 cans

Pedro has a student loan of $62,845. This loan has a simple interest rate of 7% per year. What is the amount of interest that Pedro will be charged on this loan at the end of the year?​

Answers

I believe it would be $4,399.15 because if you use the formula I=P*R*T
P=62,845
R=0.07 or 7%
T=1 year period
So overall your equation is 62845*0.07*1=$4,399.15
Now at this point the interest is added onto the principal amount to figure out some new amount after one year so:
62845.00+4399.15=$67,244.15

Which of the following is the most reasonable domain and range for the function?

Answers

Answer:A

Step-by-step explanation:A

The most reasonable domain and range for the function is x≥0, y≥0. Therefore, option B is the correct answer.

The given function is f(x) = 3000 + 100x.

We need to find which of the following is the most reasonable domain and range for the function.

What is the domain and range of the function?

The domain and range are defined for a relationship and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:

Domain = the set of all x-coordinates = {1, 2, 3, 4}

Range = the set of all y-coordinates = {2, 3}

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (-∞, ∞) {x|x∈R}

Range: (-∞, ∞) {y|y∈R}

The most reasonable domain and range for the function is x≥0, y≥0. Therefore, option B is the correct answer.

2. State whether the change is increasing or decreasing. Round your percent of change to the nearest integer percent. originally: 55 tickets presently: 90 tickets tickets ​

Answers

Answer:

The change is increasing with a percentage of change of 64%

Step-by-step explanation:

Since we have the present grater than the original, then the change is increasing

Secondly, we want to calculate the percent of change

Mathematically , that will be ;

(present - original)/original * 100%

= (90-55)/55 * 100%

= 35/55 * 100% = 63.63 which is approximately 64%

how many solutions does the quadratic have? 2x^2+3x-5​

Answers

Answer:

2 solutions

Step-by-step explanation:

Given

2x² + 3x - 5 ( to solve the quadratic equate it to zero )

2x² + 3x - 5 = 0 ← in standard form

(2x + 5)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - [tex]\frac{5}{2}[/tex]

x - 1 = 0 ⇒ x = 1

The 2 solutions are x = - [tex]\frac{5}{2}[/tex] , x = 1

Step-by-step explanation:

Solution:

Given:-

(X+y,y+3)=(6,2y)

Equating corresponding elements,we get,

X+y=6------(1)

y+3=2y-----(2)

solving equation (2),

y-2y=-3

-y=-3

y=3.

Now, substituting y=3 in equation (1)

X+3=6

X=6-3

X=3

Therefore,. (X,Y) = (3,3)
