A rectangular paperboard measuring 22 in long and 14 in wide has a semicircle cut out of it, as shown below.
Find the area of the paperboard that remains. Use the value 3.14 for pi, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
231.07 in^2
Step-by-step explanation:
The radius of the semicircle is 14/2 = 7 in
22x14 - 3.14x(7^2)/2 = 231.07 in^2
Answer: 231.07 m^2
Step-by-step explanation:
Area of the remaining paperboard = Area of the entire paperboard - Area of semicircle
1. area of paperboard = l*b = 22*14 = 308 m^2
2. area of semi circle = 1/2 pi r^2 = 1/2*3.14*49/2
Therefore, area of remaining paperboard = 231.07 m^2

Answer:
The answer is c! 7,36,60,30
Step-by-step explanation:
To answer this equation you have to find a number that fits the description of what is required. It may seem difficult but it's not first off it's trial and error you have to find the right equation for every given number. For example, what makes 15 equal 5 true? To make the equation true you have to do 15 divided by 3 equals 5 now we take the / 3 and apply them to all the other numbers so 21 / 3 is 7 , 36 divided by 3 is 12 hi, 60 / 3 is 20 , 90 /3 is 30. If you have any other question like this all you have to do is trial and error with a number to make the equation true hopefully that helps! (B.t.w / symbol means divided by)
$59.75 camera, 4% sales tax
please show in full detail
Answer:
The total cost would be: $62.14
Step-by-step explanation:
First convert the percent to a decimal, so since it is 4%, you move the decimal two places to the right, so it would be .04.
Next, multiply $59.75 x .04%. This equals $2.39.
Then, take the product and add it to $59.75. So, $59.75 + $2.39.
This equals $62.14!
The length of a rectangular field is 4 m longer than its breadth. If the perimeter of the field is 44 m calculate:
i) breadth
ii) the area of the field
Step-by-step explanation:
Breadth = 8m
Length = 8m + 4m = 12m
Area of the rectangle = length × breadth, 12m × 8m = 96m square.
A classroom is arranged with 6 seats in the front row, 8 seats in the middle row, and 10 seats in the back row. The teacher randomly assigns seats to students as they enter the classroom.
What is the probability that the first student who enters the classroom will be assigned a seat in the front row?
Answer:
[tex] \frac{6}{24} \: or \: 0.25 \: or 25\%[/tex]
Step-by-step explanation:
First add them all up to get the total amount of seats.
6+10+8=24
there are 6 seats in the front row. so that means it will be
[tex] \frac{6}{24} [/tex]
24÷6=0.25
0.25×100=25%
Probability can be answered with a fraction, decimal or a percentage, they are all correct.

Answer:
Answer to Question 1: 2.3 miles per gallon
Answer to Question 2: x = 2.371
Step-by-step explanation:
Question 1 (explanation): 36.8 (miles on one tank of gas) / 16 (gallons of gas that Fred's car hold) = 2.3 (miles that Fred's car can travel per gallon)
Question 2 (explanation): 11.001 - 8.63 = 2.371

What is the sale price of a bag of potato chips priced 4 and the sale 25% off?
A:$1.50 B:$2 C:$3 D:$2.50
Answer:
C: $3
Step-by-step explanation:
I think you're saying that the chips cost $4, so that's what I'm going with.
You can think of 25% as 1/4 of the whole. So if you divide 4 by 4, you get 1, so that means that 1/4 of the price is 1.
Now you can subtract 1 from 4 : 4-1= $3

What shape is both a rhombus and a rectangle?
A.triangle
B.trapezoid
C.Square
D.kite
The shape that is both a rhombus and a rectangle is a square (option a).
A square possesses the characteristics of both a rhombus and a rectangle. A rhombus is a quadrilateral with all sides of equal length, while a rectangle is a quadrilateral with four right angles. A square satisfies both conditions, as it has four equal sides and four right angles.
Therefore, a square can be classified as a rhombus because its sides are equal, and it can also be classified as a rectangle because it has right angles. The square is a special case where the properties of both a rhombus and a rectangle are met, making it the correct answer. The correct option is a.

2y = 0
y = 0
Solve for x
0 = x - 4
x = 4

What is the measure of the angle that the ladder makes with the wall?
Answer:
30°
Step-by-step explanation:
The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)
Measure of angle the ladder makes with the ground = 180 - 120 = 60°
Therefore,
The measure of angle the ladder makes with the wall = 180 - (60 + 90°)
= 30°
48 is 12% of what number?
Answer:
I'm not sure but from my calculations,it is 400
Answer:
400
Step-by-step explanation:
In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.
48÷0.12 or 48/0.12 = 400
Change 60% to fraction in its simplest form
Answer: 3/5
Step-by-step explanation:
60% as a fraction is 60/100.
You can simplify 60/100 to 30/50 then simplify that further to 15/25 then using the 5 times tables you can simplify that to 3/5.

The area of a rectangle knitted blanket is 9x^2-6x-8. What are the possible dimensions of the blanket? Use factoring
Answer:
(3x-4) by (3x+2) or (-3x+4) by (-3x-2)
Step-by-step explanation:
To factor 9x^2-6x-8 we want to find the factors of 9 and the factors of -8 that when multiplied in sequence and then added give us -6.
factors of -8:
-8 & 1
8 & -1
-4 & 2
4 & -2
you might also want to remember that these can be flipped, so if you have -8 & 1 you can also have 1 &-8.
factors of 9:
9 & 1
-9 & -1
3 & 3
-3 & -3
So now we just need to find numbers where
a & b are factors of 9 and c & d are factors of -8 and a*c+b*d=-6,
if that is the case then (ax+c)*(bx+d)=9x^2-6x-8
guess: 3 & 3 and -4 & 2
3*(-4) + 3*2=-12 +6 = -6
so one factoring is (3x-4)*(3x+2)
This means that one of the possible dimensions of the blanket is (3x-4) by (3x+2)
guess: -3 & -3 and 4 & -2
(-3)*4+(-3)*(-2)= -12+6 = -6
so another factoring is (-3x+4)*(-3x-2)
So you could also have a blanket with dimensions (-3x+4) by (-3x-2) but this might not make sense to do because, if you input positive numbers for x you will get negative dimensions which in the real world don't exist for a knitted blanket.
