Maggie makes $57,600 a year. Estimate how much she can afford to pay for rent each month if she budgets 27% of her gross monthly income.
She can afford to pay $1296 per month.
How much can Maggie afford to pay?Given that Maggie makes $57,600 a year, to determine how much she can afford to pay for rent each month if she budgets 27% of her gross monthly income, the following calculation must be performed:
100 = 5760027 = X27 x 57600 / 100 = X27 x 576 = X15552 = X15552 / 12 = 1296Therefore, she can afford to pay $1296 per month.

Solve square root of x + square root of x+2 = 2
The value of x is [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Given:
[tex] \sqrt{x} + \sqrt{x + 2} = 2[/tex]
Rearranging the radical on left side,
[tex]\sqrt{x + 2} = 2 - \sqrt{x}[/tex]
Power on both sides,
[tex](\sqrt{x + 2})^{2} = (2 - \sqrt{x})^{2} [/tex]
Simplifying the left,
[tex]x + 2 = (2 - \sqrt{x} )^{2}[/tex]
For the RHS equation, use the property of (a-b)² = (a²-2ab+b²),
[tex] = > x + 2 = {2}^{2} - (2 \times 2 \sqrt{x}) + ( \sqrt{x})^{2} [/tex]
Now calculating its powers,
[tex] = > x + 2 = 4 - 4\sqrt{x} + x[/tex]
Now sending -4√x to the LHS (left side), its sign becomes plus (+),
[tex] = > 4 \sqrt{x} = 4 + x - x - 2[/tex]
Now the +x and -x will be cancelled,
[tex] = > 4 \sqrt{x} = 4 - 2[/tex]
[tex] = > 4 \sqrt{x} = 2[/tex]
Bringing 4 to the right side, it becomes the denominator,
[tex] = > \sqrt{x} = \frac{2}{4} [/tex]
[tex] = > \sqrt{x} = \frac{1}{4} [/tex]
Now powering both sides,
[tex] = > ( \sqrt{x})^{2} = ( \frac{1}{2})^{2}[/tex]
[tex] = > x = \frac{1}{4} [/tex]

A rectangular garden has an area of 52 square yards. If we multiply its
length and width by 15, what is the area of the new rectangle?
OA) 1540 yd.?
OB) 12,270 yd.?
OC) 11,700 yd?
OD 270,000 yd?
Please answer soon!
Answer:
It is OC) 11,700 yd.
Step-by-step explanation:
when finding new area, take you 2 numbers, 52 and 15, square the 15, then multiply them 52 x 15^2 = 11,700
Answer:
C) 11, 700 yd²
Step-by-step explanation:
Let [tex]x[/tex] = width of a rectangle
Let [tex]y[/tex] = length of a rectangle
Area of a rectangle = width x length
⇒ area = [tex]xy[/tex]
If a rectangular garden has an area of 52 yd²
⇒ [tex]xy[/tex] = 52
If the length and width are multiplied by 15:
⇒ new width = [tex]15x[/tex]
⇒ new length = [tex]15y[/tex]
⇒ area = [tex]15x \times 15y=225xy[/tex]
If xy = 52,
new area = 225xy = 225 x 52 = 11700

Why do you think there were more than 20 riots across the nation that summer
Answer:
beacuse it was so hot and people were stealing alot and thir king suks
Step-by-step explanation:
Answer:
In the summer of 1919, over 20 race riots broke out across the nation. The worst violence occurred in Chicago. African Americans went to White Beach only and that started violence. Each sides started throwing stones at each other, and a person drowned. A full-scale riot then erupted in the city. Angry African Americans attacked white neighborhoods while whites attacked African American neighborhoods. In the end, 38 people died—15 white and 23 black—and over 500 were injured. The most serious racial outbreak occurred in Chicago late in July of the Red Summer. A African American drifted into water that was customarily used by whites, White swimmers commanded him to return to his part of the beach, and some threw stones at him. The man drowned and that caused a riot between African American and White people. 38 people had been killed, including 15 whites and 23 blacks. Hope this helps!

Adult tickets to the faculty-students basketball game sold for $5 each and student ticket was sold for $2 each. if 235 tickets were sold for a total of $725, how many of each kind of ticket were sold?
Answer:
85 adult tickets
150 children tickets
Step-by-step explanation:
we can write a system of equations and then use the 'elimination method':
let a = adult tickets
let c = children tickets
a + c = 235
5a + 2c = 725
we can multiply the first equation by -5 to get:
-5a - 5c = -1175
now we can add the second equation to get:
5a + 2c = 725
-3c = -450
c = 150
a + 150 = 235
a = 85

The quartiles of any Normal distribution are about __________ standard deviations from the mean. Give your answer to 3 decimal places.
Answer:
(1) The first quartile of standard normal distribution is -0.67.
(2) The third quartile of standard normal distribution is 0.67.
(3) The percentage of the observations in the standard normal distribution that are suspected outliers is, 0.74%.
Explanation:
A standard normal distribution has mean 0 and variance 1.
(1)
The first quartile of any data is the value below which 25% of the data lie.
That is, P (Z < z) = 0.25.
The value of z is -0.67.
Thus, the first quartile of standard normal distribution is -0.67.
(2)
The third quartile of any data is the value below which 75% of the data lie.
That is, P (Z < z) = 0.75.
The value of z is 0.67.
Thus, the third quartile of standard normal distribution is 0.67.
(3)
In case of a standard normal distribution values lying outside the range
(Q₁ - 1.5 IQR, Q₃ + 1.5 IQR)
are considered as outlier.
Compute the range as follows:
Compute the probability of (Z < -2.68) and P (Z > 2.68) as follows:
The probability of a value being an outlier is,
P (Outlier) = P (Z < -2.68) + P (Z > 2.68)
= 0.0037 + 0.0037
= 0.0074
The percentage of the observations in the standard normal distribution that are suspected outliers is, 0.0074 × 100 = 0.74%.

x = -3 + 3y (put in for x)
-2 (-3 +3y) +7y =10 ( slove for y)
6-6y +7y = 10
