Answer: 235 cm^2

Explanation: you can cut the shape into two smaller ones and then solve for each smaller shapes area. to find out the length of the top piece with 11 as length you can subtract nine from fourteen. from their you calculate the area of the top shape (11x5=55) and then the bottom shape (9x20=180). from their just add the two areas to get 235.

Answer:

246 cm squared

Step-by-step explanation:

u hv to break up the big shape into little shapes so you would do 20x9 and 20-14 which is 6 and do 6x11 and then add them up

Martha Jackson had a $396.25 average monthly expenditure for clothing during the first quarter of the year. She spent $401.50 in

Sladkaya [172]

Answer: Martha spend $537.25 in june to have the same average as in the first quarter.

Step-by-step explanation:

Given that,

Average monthly expenditure for the first quarter= $396.25

Expenditure in April= $401.50

Expenditure in May= $250.00

Suppose, expenditure in June= x

To have the same average as in the first quarter, we have to take the average of the second quarter equals to the average of first quarter.

So,

Average monthly expenditure for the second quarter= $396.25

Using the formula of average for monthly expenditure for second qaurter as follow:

Average monthly expenditure for months April, May, and June= Sum of expenditure of April, May, and June divided by 3.

So,

396.25= (401.50 + 250.00 + x)/3

1188.75= 651.5 + x

x= 537.25

How do i solve the question in the image provided ?

Mars2501 [29]

Answer:

0.19+0.46i and 0.19-0.46i

Step-by-step explanation:

$\neq (-b+\sqrt{b^2-4ac} )/2a\\and\\(-b-\sqrt{b^2-4ac} )/2a\\\\a=8\\b=3\\c=2\\(-3+\sqrt{3^2-4*8*2} )/(2*8)\\= - 0.1875+0.463512i\\(-3-\sqrt{3^2-4*8*2} )/(2*8) = -0.1875-0.463512i$

hope its right

A 3" x 5" photo is enlarged so that length of the new photo is 7 in inches

Lady bird [3.3K]

Hey

Width of the photo = 3"
Length of the photo = 5"
New length of the photo = 7 inches
Then
3/5 = x/7
5x = 7 * 3
5x = 21
x = 21/5
= 4.20 inches

Points X, Y, and Z are colinear.<br> X<br> What is the slope of YZ in simplest form?

DIA [1.3K]

Based on the calculations, the slope of line YZ in simplest form is equal to 2.

<h3>How to determine the slope of YZ?</h3>

Mathematically, the slope of a straight line can be calculated by using this formula;

$Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}$

Since points X, Y, and Z are collinear, we can deduce that the line passes through line Z at 6 units form the origin and 3 units for Y from the origin.

Substituting the parameters into the formula, we have;

$Slope, m = \frac{6\;-\;0}{3\;-\;0}$

Slope, m = 6/3

Slope, m = 2.
