Answer:
Step-by-step explanation:
Total members in the choir = 24 + 36 = 60
a) Percentage of men = [tex]\frac{24}{60}*100[/tex]
= 4 * 10 = 40%
b) Percentage of women = 60%
c) Number of men =24 + 10 = 34 men
Number of women = 36 + 10 = 46
Total = 34 + 46 = 80
Percentage of men = [tex]\frac{34}{80}*100= 42.5[/tex]%
Percentage of women = (100 - 42.5)% = 57.5%
Answer:
Solution :-a]
% of men = 24/60 × 100
% of men = 4/10 × 100
% of men = 4 × 10
% of men = 40%
b]
% of women = 36/60 × 100
% of women = 6/10 × 100
% of women = 6 × 10
% of women = 60%
c]
Men = 24 + 10 = 34
Women = 36 + 10 = 46
Total = 34 + 46 = 80
% of men = 34/80 × 100 = 42.5
% of women = (100 - 42.5) = 57.5 %

Answer:
2
Step-by-step explanation:
It's 2 because as you can see in the botton 4/10 and 8/20, 4 x 2=8 and 10 x 2=20. It's like saying you're multiplying the same thing for the top and bottom of both fractions. So, the two fractions on the top with the juice is getting multiplied by 4.

Kelly deposited $4,205 in an account for 3.5 years. She earned $662.29 in interest. What interest rate did the bank pay her?
Answer:
r = 4.5%
Step-by-step explanation:
Formula:
I = Prt
r = I/(Pt)
Given:
I = 662.29
P = 4205
t = 3.5
Work:
r = I/(Pt)
r = 662.29/(4205 * 3.5)
r = 662.29/14717.5
r = 0.045
r = 4.5%

Which expression shows the area of the base of each pyramid? (One-fourth x) squared in.2 (One-third x) squared in.2 (One-half x) squared in.2 x2 in.2
Answer:
(a) [tex]Area = (\frac{x}{4})^2[/tex]
Step-by-step explanation:
The question is incomplete. (See comment for complete question).
From the completed question, we have:
[tex]Total\ base\ length = x[/tex]
[tex]n = 8[/tex] --- number of pyramids
Required
An expression for the area of the base
The total base length of the pyramid represents the perimeter of the base.
And since the base is a square, then the following relationship exist.
[tex]Total\ base\ length = 4L[/tex]
Where L represents the length of each side.
This gives
[tex]4L = x[/tex]
Make L the subject
[tex]L = \frac{x}{4}[/tex]
The area of the base is then calculated as:
[tex]Area = L^2[/tex]
[tex]Area = (\frac{x}{4})^2[/tex]

find the circumference of a circle with a radius of 9.8 in. (urgent)
Answer: 61.58
Step-by-step explanation:
C = 2 π r = 2 · π · 9.8
π = pi
radius times pi (3.14) times 2 (because two radius makes the diameter)
9.8 times 3.14 times 2 = 61.57522in
Now we round.. 61.58

Answer:
55 bricks
Step-by-step explanation:
First find the area of one brick by multiplying 10x6x4, which is 240 cm^3. Then divide that from 13,200 which gives you 55 bricks.
Answer:
55 bricks
Step-by-step explanation:
First, we know they used 13,200 cm^3 of concrete. cm^3 is a volume, so in order to find how many bricks can be made, we must find the volume of each brick. Multiply the dimensions of each brick. 10*6*4=240cm^3. Now, divide 13,200cm^3/240cm^3=55 bricks

Which expression represents the relationship between the step number n and the total number of small squares in the pattern?
A pattern of small squares. Step 1 has 0 squares. Step 3 has 3 squares: 2 by 2 but missing the lower right square. Step 3 has 8 squares: 3 by 3 but missing the lower right square.
A.
B.
C.
D.
Answer: n squared - 1
Step-by-step explanation:
The relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.
What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given is a pattern of small squares as described -
Step 1 has 0 squares.
Step 2 has 3 squares : 2 by 2 but missing the lower right square.
Step 3 has 8 squares : 3 by 3 but missing the lower right square.
We can write the general expression for step {n} as -
Step {n} will have : 2ⁿ - 1 squares with missing the lower right square.
or
f(n) = 2ⁿ - 1
Therefore, the relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.

Will mark branliest. What can the maximum number of digits be in the repeating block of digits in the decimal expansion of 1/17?
Answer:
Step-by-step explanation:
Let n=2α⋅5β⋅m , where gcd(m,10)=1 . Then, the decimal expansion of 1n is of the form
0.a1…akak+1…ak+ℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(1) ,
where k=max{α,β} and ℓ is the least positive integer for which m∣(10ℓ−1) . In other words, ℓ is the order of 10 in the multiplicative group of units modulo m . So ℓ∣ϕ(m) by Lagrange's theorem.
In particular, if gcd(n,10)=1 , then α=β=k=0 , m=n , and
1n=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(2)
Therefore, we know that
117=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(3)
Here ℓ is the least positive integer for which 17 divides 9…9ℓtimes , and we know that ℓ divides ϕ(17)=16 .
Successively squaring 10 modulo 17 gives
102≡−2(mod17),104≡4(mod17),108≡−1(mod17),1016≡1(mod17) .
So ℓ=16 in expansion (3) .
In fact,
a1…a16×17=1016–1.
a1…a8+a9…a16=108−1 .
The first fact has nothing to do with the denominator n being prime. The second fact has everything to do with n being prime, and was discovered by E. Midy in 1836 .
Beth has already jogged 3 miles. She plans to jog less than 12 miles. Which inequality can be
used to find the number of miles (m) she has left to jog?
m - 3 < 12
m +3 > 12
m-3 > 12
m+ 3 < 12
Answer:
The total number of miles Beth plans to jog cant go over 12, and she has already jogged for 3 miles, then she needs to jog for another m miles. This can be written mathematically like: 3 + m < 12.

One store has carrots on sale for $1.1 for 3 pounds, while another store has carrots on sale for $0.78 for two pounds. Which store has the better deal?
Maria want to buy a pencil for everyone in her class. It costs $0.78 for 3 pencils. How much Maria have to spend if she bought a pencil for each of her 24 classmate?
Answer:
1) The store selling for 1.1 per 3 lbs
2) $6.24
Step-by-step explanation:
1)
1.1/3 = 0.37
0.78/2 = 0.39
0.37 is cheaper so it's a better deal
2)
[tex]\frac{0.78}{3} =\frac{x}{24} \\\\3x=18.72\\x=6.24[/tex]
Answer:
1.10 for 3 is the better deal. It will cost $6.24 for the pencils.
Step-by-step explanation:
Do two separate problems but find how much it is for 1 carrot. So the first is:$1.10 divided by 3 carrots = .366 or 37 cents per carrot.
The second one is: .78 divided by 2 carrots = .39 cents per carrot.
If you break 24 students into groups of 3, that would be 8 groups. 24 divided by 3 = 8.
8 sets of 3 pencils is .78 x 8 = $6.24

B 3 1-liter bottles for $1.50
1 liter = $1.50/3 = $0.50
C 24 0.5-liter bottles for $5.25
1 liter = 5.25 / 12 = $0.4375

3 * 1 litre bottles = 3 litres
1.50/3 = 0.5
24 * 0.5 litres = 12 litres
5.25/12 = 0.4375
36 * 0.25 liters = 9 liters
