Answer:
The composite area is a total of 62 square inches.
Step-by-step explanation:
You're given three rectangles of different width and height. To find the correct answer, you need to find the sum of each rectangles' area.
first though we need to find the height of the middle rectangle. We are told the total height and the other two rectangles' heights, so we just need to subtract the others' heights from the total:
10 - (4 + 1.5)
10 - 5.5
= 4.5
So the middle rectangle is 4x4.5 inches, giving it an area of 18 square inches
The top one is 8x4 inches for a total of 32 square inches.
And the bottom one is 1.5x8 inches, for a total 12 square inches.
If we add them all up, that's 18 + 32 + 12 square inches, or 62 square inches.

A college cafeteria pays student cashiers $540 per hour. Cashiers earn an additional
$110 per hour for each hour worked over 35 hours per week. A cashier worked 39
hours one week and 37 hours the second -week. Show and explain to the cashier how her salary
would be calculated in this two-week period?
Answer:
total hr worked = 39 + 37 = 76 hr
salary per hr = 110 $
so total salary = 110 * 76 = 8360$

Answer:
Option C
Step-by-step explanation:
Since, measure of all sides of the triangle has been given in the picture,
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(BC)cos(B)
11² = 16² + 16² - 2(16)(16)cos(B)
121 = 256 + 256 - 512.cos(B)
121 - 512 = - 512.cos(B)
cos(B) = [tex]\frac{391}{512}[/tex] = 0.763672
B = [tex]cos^{-1}(0.763672)[/tex]
B = 40.2°
Therefore, measure of angle B is 40.2°.
Option C is the answer.
Find the area. Simplify your answer.
X+8
х
Answer:
x²+8x
Step-by-step explanation:
area of rectangle
l×w
(x+8)×x
x²+8x
The area of the rectangle is [tex]X^2 + 8X[/tex].
To find the area of a rectangle, we multiply its length by its width.
In this case, the length is (X + 8)
and the width is X.
so, we have,
Area = Length * Width
Area = (X + 8) * X
To simplify the expression, we need to distribute the X through the parentheses:
Area = X * X + 8 * X
Area = [tex]X^2 + 8X[/tex]
So, the area of the rectangle is [tex]X^2 + 8X[/tex].

When James family went on the road to the carnival they were stuck in traffic. After a 20 minutes they are were 30 more miles left, after 35 minutes passed. How many more miles are left? If the fair is 58 miles away?
Answer:
They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Alyssa used a can of paint that was 5/6 full to touch paint her house. When she was done, the bucket was 11/30 full. What fraction of the can did she use?
Answer:
7 / 15
Step-by-step explanation:
Fraction before painting = 5/6
Fraction left after painting = 11/30
Fracrion used = difference of the fraction before painting and fraction left after painting
Fraction used = 5/6 - 11/30
Lowest common factor of 6 and 30 = 30
5/6 - 11/30 = (25 - 11) / 30 = 14/ 30
Fraction used = 14/30 = 7/15
A piece of paper has a rectangle ABCD in which AB= 10 cm and BC = 22 cm , it was folded to form a right circular cylinder such that AB is cincident to DC . Find the volume of the resulted cylinder
Answer: [tex]385cm^{2}[/tex]
Step-by-step explanation:
given data:
AB= 10 cm.
BC = 22 cm.
volume of a cylinder V = [tex]\pi r^{2} h[/tex]
h = 10.
solution
base of the circumference = 22cm
circumference of a circle = [tex]2\pi r[/tex]
r = radius is unknown.
[tex]2\pi r = 22[/tex] .........................eq1
where [tex]\pi = \frac{22}{7}[/tex] insert this into eq1.
[tex]2* \frac{22}{7}* r = 22[/tex]
[tex]\frac{44}{7} r = 22[/tex]
[tex]r = \frac{22}{\frac{44}{7} }[/tex]
[tex]r= 3.5cm[/tex]
next we solve for the volume of the cylinder.
recall [tex]V = \pi r^{2} h[/tex]
h = 10cm
r = 3.5cm
[tex]V = \frac{22}{7} * (3.5)^{2} *10[/tex]
[tex]V = 385cm^{2}[/tex]
Use the given data to find the best predicted value of the response variable x. Ten pairs of data yield r=0.003 and the regression equation y=2+3x, and it is determined that is not a good model. Also, the mean of y values= 5.0. What is the predicted value of y for x=2
Answer:
Step-by-step explanation:
Given the regression equation :
y=2+3x
Mean of y values ; y = 5.0
Where y is the predicted variable ; x = predictor variable
The predicted value of y for X = 2

Light travels about 186,000 mi /s. The function d(t) = 186,000t gives the distance d(t), in miles, that light travels in t seconds. How far does light travel in 30 s
D(t) = 186,000 t
D(30) = 186,000 • 30
D(30) = 5,800,000 miles
Hope this helps!
The light will travel 5,580,000 miles in 30 seconds.
To understand the calculations, check below.
Distance :The distance traveled by light is represented by function.
[tex]d(t)=186,000t[/tex]
To find the distance traveled by light in 30 seconds.
Substitute t=30 in the given function.
d(30) = 186,000 × 30
d(30) = 5,580,000 miles.
Hence, the light will travel 5,580,000 miles in 30 seconds.

Chinki has some ‘fraction bars'. The longest bar is the red one (R).
She has some purple bars (P) that are 3⁄4 of the length of the red one, some yellow bars (Y) that are 1⁄2 of the length of the red one and some green bars (G) that are 1⁄4 of the length of the red one.

Answer:
-2.1f-17
Step-by-step explanation:
combine like terms
Answer:
-2.1f-17
Step-by-step explanation:
1. Combine like terms
Like terms are those that either have the same variable, degree, or no variable at all.
Here, -2.5f and 0.4f and -14 and -3 are like terms. -2.5f and 0.4f are like terms because they both have f beside them. The reason -14 and -3 are like terms is because they both stand alone with no variables.
Combining like terms means to either add or subtract them from each other depending on their signs.
Just think of them as two separate problems for now.
-2.5f + 0.4f = ?
add these two together to get -2.1f
-14-3
Subtract these to get -17.
2. Put the expression back together: -2.1f-17
A school conference room can seat a maximum of 83 people. The principal and two counselors need to meet with the school’s student athletes to discuss eligibility requirements. If each student must bring a parent with them, what is the maximum number of students that can attend each meeting?
Answer:
40 students
Step-by-step explanation:
We do not count the counselors or the principal because they are not students, so we do 83 - 3 = 80, now it is just simple division, for every student there is a parent, so we divide 80 in half, 80 / 2 = 40 students :D

There are two areas where the circles P and C overlap. One is labeled "4" and the other is labeled "3x". The sum of these two values is the number of people who like Pop and Classical music, 13.
4 + 3x = 13
3x = 9 . . . . . subtract 4
x = 3 . . . . . . divide by 3
__
We are asked to find the number of people who like two types only. The three regions where only two circles overlap are labeled x, 3x, and 6. The answer to the question is the sum of these values.
like 2 types only: x +3x +6 = 4x +6 = 4(3) +6 = 18
18 students like two types of music only.
A publisher makes books for a number of distributors. For one book, the charge to the distributor is represented by a fixed cost of $3000 plus $16 per book. a) How much would 600 books cost b) what is the cost per book if 600 are ordered c) what is the cost per book if 1000 are ordered
Answer:
a. $12,600
b. $21
c. $19
Step-by-step explanation:
a) The cost is $3000 plus $16 per book
For 600 books, we have
3000 + 16(600)
= 3000 + 9600 = $12,600
b) Cost per book will be;
12,690/600 = $21
c) for 1000
= 3000 + 16(1000)
= 3000 + 16,000 = 19,000
cost per book is 19,000/1000 = $19
A line has a slope of -2 and a y-intercept of –3. Graph the line using the slope and y-intercept.
Which of the following points lie on this same line? Check all that apply.
(–2, 0)
(–1.5, 0)
(–6, 9)
(2, –3)
(3, –9)
(–4, 4)
Answer & Step-by-step explanation:
First write the line equation.
y=mx+b is the format where m=slope, b= y intercept
y=-2x-3
plug each x in to see if they match the point
y= -2(-2) -3 = -4 - 3 = -7 ; the point is (-2,0) so NO
y= -2(-1.5) -3= 3-3 = 0; point is (-1.5, 0) so YES it matches
y= -2(-6) -3 = 12-3 = 0; point matches so YES
y= -2(2) -3 = -4-3 = -7; point is (2, -3) so NO
y = -2(3) -3 = -6-3= -9; point matches so YES
y= -2(-4)-3 = 8-3 = 5; point is (-4, 4) so NO
