Carlton received 45 votes in the school council election, and Will received 60 votes. What percent of the votes did Carlton receive?
Answer:
42.9%
Step-by-step explanation:
The total number of votes between Carlton and Will is [tex]60 + 45 = 105[/tex].
If we put Carlton's votes in a fraction over the total number of votes, we get [tex]\frac{45}{105}[/tex].
So, if we now multiply this fraction by 100, we will get the percentage amount:
[tex]\frac{45}{105} * 100 = 42.9[/tex]
This means that to 1 decimal place, the percentage of votes that Carlton received is 42.9%.
Answer:
Carton receive:
42.86% (aprox)
Step-by-step explanation:
45 + 60 = 105
total votes = 105
Carlton received 45 votes
then:
45/105 = 0.4286 (aprox)
0.4286*100 = 42.86%
Isabella has a dozen apples of the same size and a dozen
watermelons of the same size. Isabella uses her juicer to extract 15
ounces of watermelon juice from 3 watermelons and 5 ounces of
apple juice from 9 apples. She makes a watermelon-apple juice
blend from an equal number of watermelons and apples. What
percent of the blend is watermelon juice?
90 per cent of the blend is watermelon juice.
Given that, Isabella has a dozen apples of the same size and a dozen watermelons of the same size.
Isabella uses her juicer to extract 15 ounces of watermelon juice from 3 watermelons and 5 ounces of apple juice from 9 apples.
We need to find what per cent of the blend is watermelon juice.
What is per cent?The percentage is a relative value indicating the hundredth part of any quantity. One per cent (symbolized 1%) is the hundredth part; thus, 100 per cent represents the entirety and 200 per cent specifies twice the given quantity.
Given that, she makes a watermelon-apple juice blend from an equal number of watermelons and apples.
So if she takes 9 apples, she can extract 5 ounces of juice.
By taking the same number of watermelons, that is 9 she can extract 15×3=45 ounces of juice.
Per cent of watermelon juice in the blend=45/50 ×100= 90%
Therefore, 90 per cent of the blend is watermelon juice.

How much 100% active ingredient powder would you need to add to 4 mL
of multivitamin powder that is 20% active ingredient powder in order to
strengthen the mixture to 50% active ingredient powder?
We need to add 2.4 mL of 100 % active ingredient powder to strengthen the mixture to 50% active ingredient powder
How to calculate the amount of active ingredient?The amount of each volume m = CV where
C = concentration and V = volumeThe amount of 50 % mixture, m = amount of 100 % powder + amount of 20 % powder.
M = m + m'
CV = C'V' + C"V" where
C = 50% concentration = 0.5, V = 50 % Volume, C' = 100 % concentration = 1, V' = 100 % volume, C" = 20 % concentration = 0.2 and V" = 20 % volume = 4 mLSo, CV = C'V' + C"V"
0.5V = 1 × V' + 0.2 × 4
0.5V = V' + 0.8 (1)
Also, we have that the total volume V = V' + V"
V = V' + 4 (2)
Substituting equation (2)into (1), we have
0.5V = V' + 0.8
0.5(V' + 4) = V' + 0.8
0.5V' + 0.5 × 4 = V' + 0.8
0.5V' + 2 = V' + 0.8
0.5V' - V' = 0.8 - 2
-0.5V' = -1.2
V' = -1.2/-0.5
V' = 2.4 mL
So, we need to add 2.4 mL of 100 % active ingredient powder to strengthen the mixture to 50% active ingredient powder

Ahmet borrows $700 and is charged compound interest at 15% per year. How much will he have to pay back in total after 6
years?
Give your answer to two decimal places.
Answer:
I did 700 - 15% times that answer by 6 and u get that big answer.
The required amount Ahmet needs to pay after 6 years is $1619.14.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Principal = P rate= r Time =a , n = compounding frequency
Here,
From the given data,
P = 700, r = 15% and t = 6 (n =1)
Now,
Amount = principal[1 + r/n]ⁿᵃ
Amount = 700(1 + 0.15)⁶
Amount = $1619.14
Thus, the required amount Ahmet needs to pay after 6 years is $1619.14.

The equation would be y = kx with k being a constant.
Direct variationAssuming the gravitational force is y and the mass of the body is x. y is directly proportional to the x.
Mathematically,
y = kx where k = constant.

Answer:
a^2+b^2=c^2
Step-by-step explanation:
You can apply this formula to any quadratic equation.
The Pythagorean Theorem is basically a way to find the side of a right triangle from the other two sides.
Take a look at this triangle labeled, a, b, c. (attachment)
Side a and b are called the legs. The largest side, c is called the hypotenuse.
In order to find a side, we have to use the formula…
a^2 + b^2 = c^2Let’s do an example.
Consider the following triangle.
(attachment)
We want to find side c, which is actually the hypotenuse as it is unknown.
In order to find the missing side, we have to use the formula or the Pythagorean theorem. We substitute our values into a and b, while leaving the c-side as it is because that is what we are trying to find.
[Math Processing Error]
What does 13=c mean? It means that the missing side, c, from the triangle above is 13.
What is the length of the hypotenuse? If necessary, round to the nearest tenth.
Answer:
c = 68 m
Step-by-step explanation:
Pythagorean theorem:To find the hypotenuse 'c' use Pythagorean theorem
hypotenuse² = base ² + altitude²
c² = 60² + 32²
= 3600 + 1024
= 4624
[tex]\sf c=\sqrt{4624}\\\\ c= \sqrt{2*2*2*2*17*17}=2*2*17\\\\\boxed{\bf c = 68 \ m }[/tex]

The Chee has to pay $35 to the pizza shop if she bought 12 slices of pizza this month and for x slices, the cost would be ($1.25x + 20)
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The membership costs $20 per month and members get a discounted price of $1.25 per slice of pizza.
Cost for 12 slices = 12×1.25 = $15
Total cost = 20 + 15 = $35 (for this month if she bought 12 slices of pizza)
The monthly cost for x slices of pizza:
= 1.25x + 20
x is the number of slices
Thus, the Chee has to pay $35 to the pizza shop if she bought 12 slices of pizza this month and for x slices, the cost would be ($1.25x + 20)

A population can be divided into two subgroups that occur with probabilities 60% and 40%, respectively. An event A occurs 30% of the time in the first subgroup and 50% of the time in the second subgroup. What is the unconditional probability of the event A, regardless of which subgroup it comes from
The unconditional probability of the event A, regardless of which subgroup it comes from is 38%
How to determine the probability?Let the events be represented as:
A ⇒ The event A happeningB ⇒ First subgroupC ⇒ Second subgroupSo, we have:
P(B) = 60%
P(C) = 40%
P(A | B) = 30%
P(A | C) = 50%
The probability is then calculated as:
P = P(A | B) * P(B) + P(A | C) * P(C)
Substitute known values
P = 30% * 60% + 50% * 40%
Evaluate the product
P = 38%
Hence, the probability is 38%
