Answer:
Option (E)
Step-by-step explanation:
[tex]\frac{a}{b}=\frac{c}{d}=k[/tex]
[tex]\frac{a}{b}=k[/tex]
[tex]b=\frac{a}{k}[/tex] ------(1)
[tex]\frac{c}{d}=k[/tex]
[tex]d=\frac{c}{k}[/tex] -------(2)
Since, [tex]\frac{6a+24}{md+6b}=k[/tex]
By substituting the values of b and d from equation (1) and (2),
[tex]\frac{6a+24}{\frac{mc}{k}+\frac{6a}{k}}=k[/tex]
[tex]\frac{k(6a+24)}{6a+mc}=k[/tex]
[tex]\frac{6a+24}{6a+mc}=1[/tex]
6a + 24 = 6a + mc
mc = 24
m = [tex]\frac{24}{c}[/tex]
Therefore, Option (E) will be the correct option.

the crowd at a sporting event is estimated to be 2,500 people. the exact attendance is 2,486 people. what is the percentage error?
Answer:
0.56%
Step-by-step explanation:
Percentage error
[tex] = \frac{2500 - 2486}{2500} \times 100 \\ \\ = \frac{1400}{2500} \\ \\ = 0.56\%[/tex]
The crowd at a sporting event is estimated to be 2,500 people, the exact attendance is 2,486 people, the percentage error is, 0.56%
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
The crowd estimated to be 2,500 people
The exact attendance is 2,486 people
Percentage error = ?
Percentage error = (estimated value- exact value)/estimated value×100
Percentage error = (2,500 - 2,486) /2500×100
= 0.56%
So, the percentage error is 0.56%

50% people use cellular mobile and 40% people use landline and 20% people use both. Find the probability that a person selected at random use neither.
a) 10% b) 30%
c) 70% d) 90%
Answer:
a) 10%
Step-by-step explanation:
To be able to own both (20%), you must fall into both categories. You own a cellular mobile, and you own a landline. The 20% is within the 50% + 40%.
50% + 40% = 90%
Subtract 90% from the total amount:
100 - 90 = 10
A) 10% is your answer.

Given:
The expression is
[tex](-4)\times (-4)\times (-4)\times (-4)\times (-4)\times (-4)[/tex]
To find:
The index form of given expression.
Solution:
Index form is the exponent form, it means, the number is represented in power of a number.
We have,
[tex](-4)\times (-4)\times (-4)\times (-4)\times (-4)\times (-4)[/tex]
Here, we have 6 times -4. So, we get -4 as base and 6 as index or exponent.
[tex](-4)\times (-4)\times (-4)\times (-4)\times (-4)\times (-4)=(-4)^6[/tex]
Therefore, the index form of given expression is [tex](-4)^6[/tex].

Step-by-step explanation:
[tex] \frac{x}{5.30} = \frac{70}{100} [/tex]
[tex]100(x) = 70(5.30)[/tex]
[tex]100(x) = 371[/tex]
[tex] \frac{100(x)}{100} = \frac{371}{100} [/tex]

[tex]70\% \: \: \: of \: \: \: 5.30 \: \: \: is \: \: \: 3.71[/tex]

Simplify this equation:
-4(c+2d)-2(3c-4d)
Answer:
-10c
Step-by-step explanation:
-4(c+2d)-2(3c-4d) = (-4c-8d) + (-6c+8d)
Multiply (-4) to both terms in the first bracket and multiply (-2) to both terms in the second bracket.
(-4c-8d) + (-6c+8d) = -4c-8d-6c+8d
Evaluate like terms.
-4c-8d-6c+8d = -10c

Colin was helping his uncle clean up a construction site. Colin's job was to make a neat stack of scrap wood. Each piece of wood was 1 3/8 inches thick. At the end if the day, Colin's stack was 57 3/4 inches tall. How many pieces of wood were in Colin's stack?
Answer:
a) 1/2 of an energy bar
b) 42 pieces
Step-by-step explanation:
a) Here, Franklin are 3/4 of an energy bar while Trey are 2/3 of what Franklin ate
The fraction are by Trey is 2/3 * 3/4 = 6/12 = 1/2
b) To find the number of pieces of wood present, we will need to divide the height of Colin’s stack by the thickness of each piece of wood
Mathematically, that will be;
57 3/4 divided by 1 3/8
= 231/4 * 8/11 = 42 pieces

Ted has an impressive total of 145 dimes and quarters. The collection is worth $24.25.
How many dimes and quarters does he have?
9514 1404 393
Answer:
80 dimes65 quartersStep-by-step explanation:
Let q represent the number of quarters (the higher-value item). Then 145-q is the number of dimes. The total collection is worth ...
0.25q + 0.10(145 -q) = 24.25
0.15q = 9.75 . . . . . . . . . . . . . . . . subtract 14.50; collect terms
q = 65 . . . . . . . . . . . divide by 0.15
d = 145 -q = 80
Ted has 80 dimes and 65 quarters.

Check
80 dimes: $8.00
65 quarters: $16.25

At each step after the first, we use one of the properties of equality to simplify the equation. In the first step, we use the distributive property to eliminate parentheses.

Additional comment
Note that the first step could have been "divide by -2", which would result in the equation 5x+8 = -7 -3x. Subsequent steps would add 3x, subtract 8, and divide by 8, to give a result of x=-15/8. There is usually more than one way to work a math problem.

Answer:
-5/2 is located left of -1
Step-by-step explanation:
Here, we want to select the correct option
We are comparing two numbers and the one on the left is less than the one on the right
Now, on the number line, we should notice one thing
The thing is that numbers that are less than a certain number will be positioned at the left hand side of the number
So what we have here is that the smaller number -5/2 is placed at the left hand side of -1 since it is the smaller number

Step-by-step explanation:
33.8 is the closest to half of 65.
9514 1404 393
Answer:
125
Step-by-step explanation:
The proportion you want is ...
[tex]\dfrac{\text{part}}{\text{whole}}=\dfrac{65}{\text{?}}=\dfrac{52}{100}\\\\6500=52\cdot\text{?}\qquad\text{cross multiply}\\\\\dfrac{6500}{52}=125=\text{?}\qquad\text{divide by 52}[/tex]
52% of 125 is 65.
__
Comment on the formulation
You can write the same proportion 4 ways. I find it convenient to choose one that has the unknown in the numerator. Here, that means you would write it ...
whole/part = 100/52 = ?/65
Then the solution is one step: multiply by 65.

Samantha created part of a table to show her savings. She saved at the same rate each week. Which graph shows this relationship?
Answer:
The answer is B
Step-by-step explanation:
because it is going up by 6 so graph B is the only graph going up by 6.
The correct graph is with $6, $12, $18, $24.
What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
As, from the given graph
The saving increases each week at the same rate therefore saving increases from 3rd to 4th week is 6$. this means that saving increases $6 each week.
Hence, option to is correct with $6, $12, $18, $24.
