Answer:
Your final grade would be 87.4
Step-by-step explanation:
When an assessment is worth a certain percentage of a final grade, the grade percentage of the assessment is taken from its allocated percentage of the final grade. For example:
One project is worth 15% of the final grade, and you got 100% on it. This means that the percentage it contributes to the final grade is 100% (achieved) of 15% (allocated %). 100% of 15% is 15% (15x1). This means that if you hypothetically only completed the project 100% without other assessments, your final grade would be 15%.
This is the same for the other project: 100% (achieved) of 15 (% worth of final grade) = 15.
This is because when you get 100% on the project, you get the full 15% of its worth for the final grade (if that makes sense).
So, from both projects, the final grade would be 30.
Now for the 82.
Since the projects together are worth 30% of the final grade, it means that the 82 in class is worth the remaining 70%.
82% (achieved) of 70 (worth %) = 70x0.82 = 57.4
The 82 in class contributes 57.4 towards the final grade.
Since we have 30 from the projects, and the 57.4 from the class, your final grade would be 30+57.4 = 87.4
Hope this helped!

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Mr. Johnson is going to buy a 18 3/4 of turkey for Thanksgiving.
The turkey cost $2.95 per pound at the grocery store
We need to find the closest estimate to the total cost of Mr. Johnson's turkey (before taxes)
18 3/4 pound=18.75 pound
20% of $2.85=20/100×2.95
=0.2×2.95
=0.59
Now 0.59×18.75
=11.06
Hence 11.06 is the closest estimate to the total cost of Mr. Johnson's turkey (before taxes)

Answer:
I'm not sure if this is correct, but if I'm not mistaken, it should be 26.4 multiplied by 3/7.
Step-by-step explanation:
The reasoning is actually pretty simple. First, find the distance between points F and B. (Hint: Use the Pythagorean Theorem) Then, take that distance, and multiply is by 3/7. Okay, 11.314. That means that the next point should be about 11.314 away from point F, and on the line between those points. Good Luck! I think you can figure out the rest.
Zucchini weights are approximately normally distributed with mean 0.8 pound and standard deviation 0.25 pound. Which of the following shaded regions best represent the probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds?
Answer:
0.81859
Step-by-step explanation:
We solve using z score method
The formula for calculating a z-score is is z = (x-μ)/σ,
where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Mean 0.8 pound
Standard deviation 0.25 pound
For x = 0.55 pound
z = 0.55 - 0.8/0.25
= -1
Probability -value from Z-Table:
P(x = 0.55) = 0.15866
For x = 1.3 pounds
Z = 1.3 = 0.8/0.25
= 2
Probability value from Z-Table:
P(x = 1.3) = 0.97725
The probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds is
P(x = 1.3) - P(x = 0.8)
0.97725 - 0.15866
0.81859.

6+3x+-4x=-4 what does x equal
Answer:
x=10
Step-by-step explanation:
sinplify the algebraic terms first, 3x + -4x is equals to -x, so the equation can be rewritten as 6 + -x = -4
now add x to both sides of the equation(which still holds true since you are adding to both sides)
6 = -4 + x
x = 6 + 4 = 10
Answer: x=10
Step-by-step explanation:
3x + -4x= -1x
-6 +-4= -10
-10/-1 is 10

Maylin goes to her local sporting goods store to buy socks and jogging shorts. Socks cost $10 per pair and jogging shorts cost $15 each. At her current consumption bundle pair of 4 pairs of socks and 2 jogging shorts, her marginal benefit from the last pair of socks is 20 and the marginal benefit of the last jogging short is 30. Maylin should ________.
Answer:
Maylin should purchase one unit of each socks & jogging shorts.
Step-by-step explanation:
In case of two goods, consumer is at equilibrium when marginal utility per dollar spent on last unit of the goods are equal, ie MU 1 / P1 = MU 2 / P2 (MU are the marginal utilities / marginal benefit of two goods, P are the price of two goods)
Given : MU1 (So) = 20, MU2 (JSh) = 30, P1 (So) = 10, P2 (JSh) = 15
So, equilibrium is at where MU1 (So) / P1 (So) = MU2 (JSh) / P2 (Jsh)
20/10 = 2, & 30/15 = 2. MU's per dollar are equal for both.
So Maylin is in equilibrium, she should purchase one unit of each socks & jogging shorts.
The consumption schedule for Maylin is given as
4 pairs of socks at $10 per pair
2 jogging shorts at $15 per short
Marginal benefit from socks = MUs = 20
Marginal benefit from socks = MUj = 30
To maximize utility. The necessary condition =
[tex]\frac{MUs}{Ps} =\frac{MUj}{Pj} \\\\\frac{20}{10} =\frac{30}{15}[/tex]
2 = 2
The condition is fulfilled because the utility maximization is met.
Therefore Maylin should leave her consumption bundle unchanged.

Given that c: d = 1: 9
find, in its simplest form, the ratio a: b
Answer:
[tex]\displaystyle a:b=\frac{1}{3}[/tex]
Step-by-step explanation:
Ratios
We are given the following relations:
[tex]a=\sqrt{7}+\sqrt{c}\qquad \qquad[1][/tex]
[tex]b=\sqrt{63}+\sqrt{d}\qquad \qquad[2][/tex]
[tex]\displaystyle \frac{c}{d}=\frac{1}{9} \qquad \qquad [3][/tex]
From [3]:
[tex]9c=d[/tex]
Replacing into [2]:
[tex]b=\sqrt{63}+\sqrt{9c}[/tex]
We can express 63=9*7:
[tex]b=\sqrt{9*7}+\sqrt{9c}[/tex]
Taking the square root of 9:
[tex]b=3\sqrt{7}+3\sqrt{c}[/tex]

The answer to this is / 7c -70
7c-70 is the Answer
first you want to do distributive property. since the -10 is on the outside of the parentheses, you multiply it by the numbers that are in the parentheses. After you do this, the equation should look like
50c-40c-70-3c
Then, you want to combine like terms. The 70 does not have a variable so you want to combine the one with exponents which are 50c,-40, and 3c
50-40 is 10. Then you would add the variable: 10c 10c-3c is 7c once all like terms are combined the equation should look like this:
7c-70

Find the Simplify interest earned $720, 5% 2 years A. 74 B.73 C.75 D.72 PLZZZZZZ HELP ME ANYNONE ;(
Answer:
Option D, 72
Step-by-step explanation:
Before touching the question, Let me tell you something about simple interest.
Simple Interest: It is something that is calculated for the additional amount paid on a loan amount. The formula for simple Interest is given by, SI = (P × R × T)/100 where, P specifies principal, R specifies rate, and T denotes time.
Now, Let's go for solving the question.
Simple Interest = P × R × T/100
0r, Simple interest = (720 × 5 × 2)/100
0r, Simple Interest = 72 × 2 × 5/10
0r, Simple Interest = 72
Hence, 72 is the required answer.

A community pool offers two types of memberships: monthly and yearly. At the beginning of the year the ratio of monthly to yearly was 10:3. However the pool offered an incentive to have members change to the yearly membership. After the incentive the ratio was 5:8. If there were 59 monthly members after the incentive, then there were how many monthly members before the incentive?
Answer:
There were 118 monthly members before the incentive
Step-by-step explanation:
Let the total number of incentive
Monthly membership after incentive = a
Yearly membership after incentive = b
a/b = 5/8
We are told in the question that: 59 monthly members after the incentive,
5/8 = 59/b
Cross Multiply
5b = 59 × 8
b = 59 × 8/5
b = 472/5
b = 94.4
Therefore, number of yearly members = 94.4
Total number of Membership after incentive
= 94.4 + 59
= 153.4
Note that total number of members before incentive = total number of members after incentive
From the question, At the beginning of the year the ratio of monthly to yearly was 10:3.
Monthly membership after incentive = a
Yearly membership after incentive = b
a/b = 10/3
10b = 3a
b = 3a/10
a + b = 153.4
a + 3a/10 = 153.4
10 × a + 3a × 1/ 10 = 153.4
10a + 3a = 10 × 153.4
13a = 1534
Divide both sides by 13
a = 1534/13
a = 118
Therefore, the number of members before monthly incentive = 118
