The total number of questions is an illustration of proportions
The total number of questions is 200
How to determine the total questions?From the question, we have:
Grade = 87%
Questions answered = 174
Represent the total questions with x.
So, the total question is calculated as:
174 = 87% * x
Make x the subject
x = 174/87%
Evaluate the quotient
x = 200
Hence, the total number of questions is 200

Answer:
2: Rate of change is the comparision between the x and y values. 3: For one pound of fish, it costs $15
Step-by-step explanation:
2: For example, if you have 4y and 1x, the rate of change is 4 because rise/run, 4/1= 4
3: The cost would be y while pounds of fish would be x. so $15/1 pound = 15
Hope this helps
Answer:
Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable. ... Subtract one and multiply the resulting number by 100 to give it a percentage representation.
Step-by-step explanation:
2. Say you have like 5y and 1x, the rate of change is 5 because rise/run, 5/1= 5

If you invest $5,000 at 1.8 percent for 5 years, compounded semi-annually, what is the amount in the account at the end of 5 years?
$5,450
$5,469
$5,470
$5,560
Answer: B: $5,469
Step-by-step explanation:
Here is the formula for compound interest:
CI = P(1 + r/n)^rt, where n is the number of times the interest is compounded in a year. In our case, since there is semi annual compounding, n = 2.
The rest of the formula can be filled out:
CI = 5000(1 + 0.018/2)^(5x2)
CI = 5000(1.009)^10
CI = 5000(
.: CI ≅ $5468.67
Thus the answer is B.

Answer: Axis of Symmetry at x=1
Step-by-step explanation:
Internet Definition: The axis of symmetry is the vertical line that goes through the vertex of a parabola so the left and right sides of the parabola are symmetric. To simplify, this line splits the graph of a quadratic equation into two mirror images.
So pretty much you see the "hill shape" on the graph... the highest part of the hill is the axis of symmetry so the axis of symmetry is at x=1

How many ml of a 50% sugar solution must be mixed with 10 ml of a 68% sugar solution to make a 62% solution?
Answer:
well first we need to see the total percent of sugar solution there is.
So first we need to add 50%+68%=118%/200%
so now 62%/100% needs translated to /200%.
We get 124%/200% Now 50%/100%=100%/200% 68%/100%=136%/200%
62% would be in a total of needed of like 7 ml of the 50% sugar solution i think let me know if i am wrong

What is the number line?The number line is the way of representation of number and digits in a arranged form to understand the data batter.
Plot startroot 0.9 endroot on the number line. The number line for the √0.9 is plotted and attached in the below image.
The value of √0.9 is greater than the zero as shown. Hence the correct inequality is,
[tex]0 < \sqrt{0.9}[/tex]
On the number line, the √0.9 is less than the number √1. Thus,
[tex]\sqrt{0.9} < \sqrt{1}[/tex]
Hence, the inequality which are true when the number line for √0.9 is plotted are,
[tex]0 < \sqrt{0.9}[/tex]
[tex]\sqrt{0.9} < \sqrt{1}[/tex]

2. Express the number 77 ten in base number
The 21603 base seven and 77 base ten are number bases
21603 base seven represents 5442 in base ten77 base ten represents 130 in base sevenHow to rewrite the numbers
1. What base ten number does 21603 seven represent?
This is represented as:
[tex]21603_7[/tex]
To convert to base 10, we have:
[tex]21603_7 = 2 * 7^4 + 1 * 7^3 + 6 * 7^2 + 0 * 7^1 + 3 * 7^0[/tex]
Evaluate the sum and the exponents
[tex]21603_7 = 5442[/tex]
Hence, 21603 base seven represents 5442 in base ten
2. Express the number 77 ten in base number
This is represented as:
[tex]77_{10}[/tex]
To convert to a base number (say base 7), we have:
77/ 7 = 10 R 0
10/7 = 1 R 3
1/7 = 0 R 1
Hence, 77 base ten represents 130 in base seven
