Answer:
First you have to find out how many he paints in 1 week.
Divide 91/7
You should then have 13 as your answer.
Then do 13 times 4 which would equal 52.
4 weeks = 52 portraits
If you want to see if it is right you can add 13 from 52 and once your at 7 you'll have 91.
Hope this helps! :)
AE = EC and BF = FC. EF = 8 and DF = 10. AB = [?]
Answer:
Therefore AB is 16 units.
Step-by-step explanation:
Given:
AE = EC
BF = FC
EF = 8 and DF = 10
To Find:
AB = ?
Solution:
Mid Point Theorem:
The Midpoint Theorem states that "the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side".
AE = EC .....Given
Therefore E is the Mid Point of AC.
BF = FC .....Given
Therefore F is the Mid Point of BC.
Therefore,
EF || AB ........................Mid Point Theorem.
[tex]EF=\dfrac{1}{2}AB[/tex] ..............Mid Point Theorem.
Substituting the values we get
[tex]8=\dfrac{1}{2}AB\\\\AB=8\times 2=16\ units[/tex]
Therefore AB is 16 units.

The perimeter of the square can be represented by the expression 36x+44 robin wants to write an equivalent expression for the perimeter that shows the side length of the square
Answer:
4 (9 x + 11) is an equivalent expression for the perimeter that shows the side length of the square is (9 x + 11).
Step-by-step explanation:
Here, given The perimeter of the square = (36 x+44)
Now,as we know :
PERIMETER OF SQUARE = 4 x ( SIDES)
Simplifying the perimeter expression.
Take 4 common out of the expression (36 x+44), we get:
(36 x+44) = 4 (9 x + 11)
⇒ Perimeter of the square = 4 x (9 x + 11)
⇒4 x ( SIDES) = 4 x (9 x + 11)
⇒ Each Side = (9 x + 11)
Hence, 4 x (9 x + 11) is an equivalent expression for the perimeter that shows the side length of the square is (9 x + 11).
Write a system of two equations.
A system of linear equation consists of two or more linear equations with the two or more same variables. Such equations are called system of equations (or) simultaneous equations (or) a pair of equations.
Example:
x + y = 5 is one linear equation.
2x – y = 4 is another linear equation.
But x + y = 5, 2x – y = 4 together they form system of linear equation.
The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Answer:
A liner equation is an equation between two variables that gives a straight line when plotted on a graph.A system of linear equation consists of two or more linear equations with the two or more same variables.
Step-by-step explanation:
x + y = 5 and 2x – y = 4 together they form a linear equation.

Andrew and Elena knew that after 28 days they would have 2^28 coins, but they wanted to find out how many coins that actually is Andrew wrote: 2^28=2×28=56. Elena said, " No, exponents mean repeated multiplication. It should be 28×28, which works out to be 784." Do you agree with either of them? Explain your reasoning.
Both Andrew and Elena are wrong. The actual value of 2^28 equals 268,435,456.
Step-by-step explanation:
Elena was right when she said exponents mean repeated multiplication but she accidentally calculated the value of 28^2 instead of 2^28. 2^28 means that the number 2 should be multiplied with itself for 28 times.
2^2 means 2 multiplied by 2 equals 4. 2^3 means 2 multiplied by 2 and then multiplied by 2 again which equals 8. Similarly, if you multiply 2 with itself 28 times you will get a value of 268,435,456 (two hundred and sixty-eight million, four hundred and thirty-five thousand, four hundred and fifty-six). So Andrew and Elena will have 268,435,456 coins after 28 days.
Ibuki factored 12 xZ as (4x) (3x4)
Melodie factored 12x7 as (2x (6x)
Who factored correctly?
Neither Ibuki nor Melodie factored 12x² correctly based on the expressions given. However, if Melodie's (2x)(6x) was meant for 12x², then her factorization would be correct.
Explanation:The students are attempting to factor the expression 12x². Factoring is the process of finding two or more expressions that multiply together to get the original expression. Ibuki's factorization of 12x² as (4x)(3x⁴) contains an error since 3x⁴ would imply raising x to the fourth power, which is not present in the original expression. Melodie's factorization of 12x² as (2x)(6x) is also incorrect since when you multiply 2x and 6x, you get 12x², not 12x⁷ as her expression suggests. The correct factorization of 12x² is (2x)(6x) since 2x multiplied by 6x equals 12x².
In summary, neither student has factored the expression correctly. However, if we take Melodie's answer as a typo and she meant (2x)(6x) for 12x², then her factored form would be correct.

the drama club at school sells $15.00
coupon books. Their profit is 35% of the
total sales. What is their profit on each
book?
The profit on each book is $ 5.25
Solution:
Given that, the drama club at school sells $ 15.00 coupon books
Their profit is 35% of the total sales
Therefore,
Cost of a coupon book = $ 15
Profit = 35% of the total sales
We have to find the profit on each book
If a book is sold for $ 15 and then profit will be 35 % of 15
Let us find 35 % of 15
[tex]Profit\ on\ each\ book = 35 \% \times 15\\\\Profit\ on\ each\ book = \frac{35}{100} \times 15\\\\Profit\ on\ each\ book = 0.35 \times 15\\\\Profit\ on\ each\ book = 5.25[/tex]
Thus profit on each book is $ 5.25
Which of the following is equivalent to the expression i^22?
Answer:
Step-by-step explanation:
[tex]i^{22}=i^{2*11}=(i^{2})^{11}=(-1)^{11}=-1[/tex]
Answer:
i^22 = -1.
Step-by-step explanation:
i^22 = (i^4)^5 * i^2
Now i^2 = -1 ( by definition)
and i^4 = i^2 * i^2 = -1 * -1 = 1
So i^22 = 1^5 * -1
= 1 * -1
= -1.

Use the Pythagorean theorem to find the unknown side of the right triangle.
15
36
A right triangle has a vertical side of length 15, a horizontal side of length 36, and an unlabeled hypotenuse.
Hypotenuse lengthequals=3 StartRoot 169 EndRoot3169
(Simplify your answer. Type exact answers, using radicals as needed.)
The length of hypotenuse is 39.
Step-by-step explanation:
Given,
Vertical side = a = 15
Horizontal side = b = 36
Hypotenuse = c
Using pythagorean theorem
[tex]a^2+b^2=c^2\\(15)^2+(36)^2=c^2\\225+1296=c^2\\1521=c^2\\c^2=1521[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{1521}\\c=39[/tex]
The length of hypotenuse is 39.

The camera was $824.99 but I had to pay the additional 10% tax. What did I pay in total for my camera?
Answer:
$907.489
Step-by-step explanation:
Cost of camera : $824.99
Tax = 10%
tax on camera = 824.99 x 10 /100 = 82.499
total amount to be paid = cost + tax
$824.99 + $82.499 = $907.489
Answer:
$907.49
Step-by-step explanation:
Figure out what 10% of 824.99 is. You should get 82.499 which you round up to the nearest hundredth because this is money which gives you 82.50.
824.99+82.50=907.49

take what each person paid, $12, and multiply by the number of people
$12(5)=$60
The total bill at the restaurant was $60, calculated by multiplying the amount each person paid ($12) by the number of people (5).
Explanation:In this Mathematics problem, Bill and his four friends, for a total of five people, decided to equally divide the restaurant bill. Each person paid $12. In order to find the total bill, we must multiply the amount each person paid by the number of people. This means, we multiply $12 by 5, which gives us a total bill of $60.

workers is:
$ US
5 people earn $25,000, 3 earn $27,000, and 1 earns $34,000
What is the mean salary and standard deviation (to the nearest dollar) of the workers?
Answer:
The mean is 26666.67 and the standard deviation is 372919430.33.Step-by-step explanation:
The mean means the average of the numbers.
The mean will be [tex]\frac{25000\times5 + 27000\times3 + 34000}{5 + 3 + 1} = \frac{240000}{9} = 26666.666666666[/tex].
The differences of the earnings from the mean are 1666.67, 26997.33, 33997.33.
Squaring the numbers we get, 2777788.89, 728855827.13, 1155818447.12.
We need to find the mean of the above numbers to get the standard deviation.
Thus, the standard deviation is [tex]\frac{2777788.89\times5 + 728855827.13\times3 + 1155818447.12}{9} = 372919430.33[/tex].
