Answer:
$1,467.20
Step-by-step explanation:
Adjusted monthly income is the gross income minus any payments made every month. 5600 - 360 = 5240. To get 28% of her adjusted income multiply 5240 X.28 =1467.20
To calculate 28% of $5600, multiply 5600 by 0.28. The result is $1568, which is 28% of Adeva's gross monthly income.
Explanation:The issue is figuring out 28% of Adeeva's gross monthly salary, which is fixed at $5600. The calculation is simple to perform using the (Amount/Total) x 100 rule for percentage calculations. The decimal equivalent of 28% is 0.28, so multiply $5600 by that number to get 28%. The computation yields a value of $1568. Therefore, $1568 or 28% of Adeeva's gross monthly revenue. By analyzing particular sections of overall profits, this technique demonstrates a fundamental use of percentages, enabling accurate financial computations and planning.

What is the area of the trapezoid?
Answer:
24 units ²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b the parallel bases
Counting the squares in the diagram gives
h = 4, a = 4, b = 8, thus
A = [tex]\frac{1}{2}[/tex] × 4 × (4 + 8) = 2 × 12 = 24 units²
Which expression can be used to determine the length of segment AB?

A state park has a normally distributed daytime temperatures in the month of June. The mean temperature is 75 Fahrenheit and then standard deviation of 7. What is the probability the temperature is above 82F?
Answer:
0.16
Step-by-step explanation:
This probability is the area under the standard normal curve to the right of 82. Note that 82 is ONE standard deviation above the mean: 75 + 7 = 82.
According to the Empirical Rule, 68% of data lies within one standard deviation of the mean. In other words, 34% lies between the mean and one standard deviation above the mean. The remaining area under the standard normal curve is thus (100% - 68%), or 32%. Half of that is 16%.
The probability that the temperature is above 82, or above 1 standard deviation above the mean, is 16%, which we can also express as 0.16.
Alternatively, use a calculator with built-in statistical functions. In this case the desired result is found by executing the following command:
normcdf(82, 10000, 75, 7). The desired result is 0.1587, or approximately 0.16.
y is directionally proportial to x, when y = 30 and x = 6, work out an equation connecting x and y
Answer:

6 people sharing 40 lbs of gold evenly. How many do they get? Then subtract 1 2/3 from the result of the problem above & simplify completely. Please help cause it's not accepting what I have
Answer: 6
Step-by-step explanation:
Given Data:
Number of people = 6
Amount of Gold to be shared = 40lbs
Subtract 2/3 from your answer.
Therefore
If six people are to share 40lbs of gold evenly
= 40lbs / 6
Divide through by 2
= 20lbs / 3
= 20lbs / 3 - 2/3
= 18/3
= 6
Each person would get approximately 6lbs of gold
Answer:
1. Each individual gets [tex]6\frac{2}{3}lb[/tex] of gold
2. After subtracting by [tex]1\frac{2}{3}[/tex] , the result is 5
Step-by-step explanation:
Given
Size of Gold = 40 lbs
Number of people = 6
Required
1. Proportion of each individual
2. Subtract [tex]1\frac{2}{3}[/tex] from each proportion
1. Proportion of each individual
To calculate how many each individuals get (in other words, the proportion of each individual), we simply divide the total size of gold by the number of people
Mathematically,
[tex]Proportion = \frac{Total}{People}[/tex]
[tex]Proportion = \frac{40}{6}[/tex]
Reduce fraction to lowest term by dividing numerator and denominator by 2
[tex]Proportion = \frac{20}{3}[/tex]
Convert to mixed fraction
[tex]Proportion = 6\frac{2}{3}[/tex]
Hence each individual gets [tex]6\frac{2}{3}lb[/tex] of gold
2. Subtract [tex]1\frac{2}{3}[/tex] from each proportion
This is represented by
[tex]6\frac{2}{3} - 1\frac{2}{3}[/tex]
Convert both fractions to improper fractions
= [tex]\frac{20}{3} - \frac{5}{3}[/tex]
Find LCM of both fractions
= [tex]\frac{20 - 5}{3}[/tex]
Subtract

The Pyramid Arena in Memphis, Tennessee is about 98 meters tall
and has a square base with a side length of about 180 meters. A prism-shaped
building has the same square base as the Pyramid Arena. What is the height of
the building if it has the same volume as the Pyramid Arena?
Answer:
Height of the building is 32.67 meters.
Step-by-step explanation:
Volume of a Pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height})[/tex]
Side of the square base of the Memphis pyramid = 180 m
Height of the pyramid = 98 meters
Volume = [tex][\frac{1}{3}(180)^2](98)[/tex]
= 1058400 cubic meters
Another building having the same base and volume, is in the shape of a prism.
Therefore, Volume of the pyramid = volume of the building(prism) = 1058400 cubic meters
Volume of the prism = (Area of the base) × height
1058400 = (180)²h
h = [tex]\frac{1058400}{180\times 180}[/tex]
h = 32.67 meters
Therefore, height of the building in the prism shape is 32.67 meters.

Find 3 consecutive integers whose sum is 105.
Answer:
34 + 35 + 36 = 105
Step-by-step explanation:
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 105
3X + 3 = 105
3X + 3 - 3 = 105 - 3
3X = 102
3X/3 = 102/3
X = 34
Which means that the first number is 34, the second number is 34 + 1 and the third number is 34 + 2. Therefore, three consecutive integers that add up to 105 are 34, 35, and 36.
34 + 35 + 36 = 105
We know our answer is correct because 34 + 35 + 36 equals 105 as displayed above.
There are 43 students in a classroom with 5
tables. If 8 students can sit at a table, how
many students cannot sit down at tables?
5
Answer:
3
Step-by-step explanation:
8 x 5 = 40
43 - 40 = 3
The number of students who cannot sit at tables based on the given conditions in a classroom setting are 3.
The number of students who cannot sit at tables can be calculated as follows:
Number of students per table = 8
Total number of students = 43
Total number of students that can be accommodated by tables = 5 tables x 8 students = 40 students
Number of students who cannot sit at tables = Total number of students - Total number accommodated by tables = 43 - 40 = 3 students
A theatre sells two types of tickets to their plays; children’s tickets and adult tickets. For today’s performance they have sold a total of 1180tickets. Also, the have sold 80 more adult tickets than children’s tickets. How many adult tickets have they sold?
Answer:
630
Step-by-step explanation:
Let the number of adult tickets be a.
Let the number of children tickets be c.
For that day's performance, they have sold a total of 1180 tickets. That means that:
a + c = 1180 _____________ (1)
Also, they have sold 80 more adult tickets than children’s tickets.
This means that:
a = c + 80 ______________(2)
Putting (2) in (1):
c + 80 + c = 1180
2c + 80 = 1180
Collecting like terms:
2c = 1180 - 80
2c = 1100
c = 1100 / 2 = 550
From (2):
a = 550 + 80
a = 630
They sold 630 adult tickets.
Final answer:
The theatre has sold 630 adult tickets after solving a system of equations based on the given conditions of total tickets sold and the difference between adult and children's tickets.
Explanation:
The student is presented with a problem where a theatre sells two types of tickets: children's and adult's tickets. For a particular performance, a total of 1180 tickets were sold, and there are 80 more adult tickets sold than children's tickets. We can let 'x' represent the number of children's tickets sold, and thus 'x + 80' will represent the number of adult tickets sold. According to the information given:
x + (x + 80) = 1180
Solving for 'x' we get:
2x + 80 = 1180
2x = 1100
x = 550
Now, to find the number of adult tickets sold, we add 80 to the number of children's tickets.
x + 80 = 550 + 80
x + 80 = 630
Therefore, the theatre has sold 630 adult tickets.

Let R1 and R2 are the remainders when the polynomials x^3 + 2x^2 − 5ax − 7 and x^3 + ax^2 − 12x + 6 are divided by x + 1 and x − 2 respectively. If R1+R2 = 6, find the value of a.
Answer:
2.44
Step-by-step explanation:
Given: x³ + 2x² - 5ax - 7 and x³ + ax² - 12x + 6
Also, R1 + R2 = 6
in order to find the value of a:
Let p(x) = x³ + 2x² - 5ax - 7 and q(x) = x³ + ax² - 12x + 6
Using remainder theorem i.e if a polynomial p(x) is divisible by polynomial of form x - a then remainder is given by p(a).
Then,
R1 = p( -1 ) = (-1)³ + 2(-1)² - 5a(-1) - 7 = -1 + 2 + 5a - 7 = 5a - 6
R2 = q( 2 ) = 2³ + a(2)² - 12(2) + 6 = 8 + 4a - 24 + 6 = 4a - 10
Now,
R1 + R2 = 6
5a - 6 + 4a - 10 = 6
9a = 22
a=2.44
Therefore, Value of a is 2.44
Quita bought a jacket priced at $88. The sales tax rate on the jacket was 7.5%. How much was the sales tax in dollars and cents on this jacket?
Need help !!!
Answer:
i think the answer is 3.3
Step-by-step explanation:
Final answer:
Quita paid $6.60 in sales tax for an $88 jacket.
Explanation:
To calculate the sales tax Quita had to pay for her jacket, we need to follow a simple two-step process.
First, we will calculate the amount of tax by converting the percentage to a decimal and then multiplying it by the price of the jacket.
Since the tax rate is 7.5%, we convert this to a decimal which gives us 0.075.
Then, we multiply this decimal by the price of the jacket:
Amount of sales tax = price × rate of sales tax
$88.00 × 0.075 = $6.60
So, the sales tax on the jacket priced at $88 is $6.60.
