The ratio of boys to girls in a college marching band is 5:6. If there are 121 total students in this band, how many boys are in the band?
Answer:
Step-by-step explanation:
The ratio of boys to girls in the band is 5:6 and there are a total of 121 people.
We can call each bit of the ratio 'parts'.
So, there are a total of 5+6=11 parts in total, and there are a total of 121 people.
Therefore, each part of the ratio is equal to 121 ÷ 11 = 11.
Since there are 5 parts assigned to the number of boys in the band, then the total number of boys in the band is equal to 11 × 5, which is equal to 55 boys.

Answer:
100(10t-x)
Step-by-step explanation:
factor 100 out from the expression
Samuel invested money in his bank account. He had a principal, P, of $100 in his account at the beginning of the period, which increased at a rate, r, of 0.15 per year. At the end of the period, he had interest, I, of $105 in his account. Use the simple interest formula I = Prt, to solve for the time, t, in months that it took to earn this amount.
Hey there! I'm happy to help!
Let's see what we have for each variable.
I = 105
P = 100
r = 0.15
Now, let's plug it in and solve for our t (time)
105=100(0.15)(t)
Swap sides so t is on the left.
100(0.15)(t)=105
Divide both sides by 100.
0.15t=1.05
Divide both sides by 0.15
t=700
So, we see that it takes 700 months to earn this amount.
Have a wonderful day and keep on learning! :D
The number of months that it took to earn this amount will be 84 months.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
I = (PRT)/100
Where P is the principal, R is the rate of interest in percentage, and T is the time.
Samuel invested money in his bank account.
He had a principal, P, of $100 in his account at the beginning of the period, which increased at a rate, R, of 0.15 per year.
At the end of the period, he had interest, I, of $105 in his account.
105 = 100 x 0.15 x t
t = 1.05 / 0.15
t = 7 years
The number of months that it took to earn this amount will be
⇒ 7 x 12
⇒ 84 months
The number of months that it took to earn this amount will be 84 months.

What is the measure of ZA?
Select the best answer from the choices provided.
A. 35
B. 55°
С.70°
D.110°
Answer:
55°
Step-by-step explanation:
Since two of the sides are the same length, that means ∠A and ∠B are the same.
All angles of a triangle add up to 180°
180 - 70 = 110
To find ∠A, we just divide 110 by 2
110 ÷ 2 = 55
Both ∠A and ∠B are 55°
raise the quotient of r and 6 to the 3rd power!!!!!!!!! IF YOU HELP RIGHT AWAY YOU GET A BRAINLY THIS IS 7th GRADE!!!!!!!
Explanation:
The expression r/6 is the quotient of r and 6. The quotient is the result of a division problem. For example, the quotient of 100 and 25 is 4 because 100/25 = 4.
We'll then raise r/6 to the 3rd power to get the final answer (r/6)^3
We could rewrite it in its equivalent form (r/6)^3 = (r^3)/(6^3) = (r^3)/216, but the answer in bold is sufficient in my opinion.

Q.3. 3p=6*7
3p=42
p=42/3
p=16
Q.4. 2(x+5)=24
2x+10=24
2x=24-10
2x=14
x=14/2
x=7
Step-by-step explanation:
For Q1.
1. x + 5 = 8
x = 8 - 5
x = 3
2. -3x + 7 = 16
-3x = 16 - 7
-3x = 9
x = 9/-3
x = -3
3. 3P/7 = 6
3P = 6*7
3P = 42
P = 42/3
P = 14
4. 2(x + 5) = 24
2x + 10 = 24
2x = 24 - 10
x = 14/2
x = 7
5. x/5 - 8 = 9
x/5 = 9 - 8
x = 5
For Q.2:
1. 12 + 4(x + 3(x + 4)) = 108
12 + 4(x + 3x + 12) = 108
12 + 4x + 12x + 48 = 108
60 + 16x = 108
6x = 108 - 60
x = 48/6
x = 8
2. 5x + 7(4 - (x + 3)) = 31
5x + 28 - x + 3 = 31
6x + 31 = 31
6x = 0
x = 0
3. 2(3y - 2(y + 5) + 3) = -4
2(3y - 2y + 10 + 3) = -4
2(y + 13) = -4
2y + 26 = -4
2y = 30
y = 15
4. 20 - 2(2x -(2 - x) + 10) = -44
20 - 2(2x - 2 + x + 10) = -44
20 - 2(3x + 8) = -44
20 - 6x - 16 = -44
4 - 6x = -44
-6x = -44 - 4
-6x = -48
x = -48/-6
x = 8
5. 5(3x - 4(x + 2) + 5(2x + 1)) = 60
5(3x - 4x - 8 + 10x + 5) = 60
5(3x - 4x + 10x - 8 + 5) = 60
5(9x - 3) = 60
45x -15 = 60
45x = 60 + 15
x = 75/45
x = 1.67
For Q.3:
1. x/2 + x/3 = 10
(3x + 2x)/6 = 10
5x/6 = 10
5x = 60
x = 12
2. 1/3(2x/7 - 1) = 3
1/3(2x - 7/7) = 3
2x - 7/7 = 3/(1/3)
2x - 7/7 = 1
2x - 7 = 7
2x = 14
x = 7
3. (P + 2/2) + ( 2P - 6/4) = 5
(2P + 4 + 2P - 6)/4 = 5
(4P - 2)/4 = 5
4P - 2 = 20
4P = 22
P = 5.5
4. x/3 - (2x + 1)/3 - (x - 3)/5
(x - 2x + 1)/3 - (x - 3)/5
(1 - x)/3 - (x - 3)/5
(5 - 5x - 3x - 9)/15
(-8x - 4)/15
5. (y - 2)/3 + (2y + 5)/5 - (y + 7)/3
5/3 + (2y + 5)/5
(25 + 6y + 15)/15
(40 + 6y)/15

The average length of time that three computers operate on a given day is 960 minutes. None of the computers operate for less than 930 minutes. What is the greatest possible length of time any one of the computers operates
The greatest possible length of time will be "1020 min".
Given:
The average length of time,
= 960
For all 3 computers,
The minimum length of time,
= 930
Let,
The length of time of 2 computers will be "930".The 3rd one be "930+x".Now,
→ [tex]\frac{930+930+930+x}{3} = 960[/tex]
→ [tex]\frac{930+930+930}{3} +\frac{x}{3} =960[/tex]
→ [tex]\frac{3\times 930}{3} +\frac{x}{3} =960[/tex]
→ [tex]930+\frac{x}{3}=960[/tex]
→ [tex]\frac{x}{3} = 960-930[/tex]
→ [tex]x = 30\times 3[/tex]
→ [tex]x = 90[/tex]
hence,
The greatest possible length of time will be:
= [tex]930+x[/tex]
= [tex]930+90[/tex]
= [tex]1020 \ min[/tex]

The selling price of a refrigerator, is $638.00. If the markup is 10% of the dealer's cost, what is the dealer's cost of the refrigerator?
25% markup = original + 25% = 125% of original = 1.25 x original
Selling price = 1.25 x dealer price
Answer = 521.25/1.25=$417
The dealers price would be 100% they sell it for 10% more so it is sold at 110 % of what the dealer pays.
Divide the selling price by 110% to get the dealers cost.
638 / 110% = 638 / 1.1 = 580
The dealers cost is $580
