Answer:
Step-by-step explanation:
Area of the figure = area of semicircle + area of rectangle
Rectangle:
length = 11.25 in
width = 7.5 in
Area of rectangle = length * width
= 11.25 * 7.5
= 84.375 in²
Semicircle:
diameter = width of the rectangle
d = 7.5 in
r = diameter 2 = 7.5/2 = 3.75 in
[tex]Area \ of \ circle = \dfrac{1}{2}\pi r^{2}\\\\[/tex]
[tex]=\dfrac{1}{2}*3.14*3.75*3.75\\\\= 22.08 \ in^{2}[/tex]
Area of the figure = 84.375 + 22.08
= 106.455
= 106.46 in²
Given that the area of a rectangle is 4 2/3 in and the is 1 1/2 find the width
Answer:
3 1/9
Step-by-step explanation:
divide 4 2/3 and 1 1/2 together to find width

A rental car company charges $77.50 per day to rent a car and $0.10 for every mile driven. Sydney wants to rent a car, knowing that:
Answer:
Step-by-step explanation:
answer: owen can afford to keep and drive the car for 4 days.
The total owing on the car rental is R(d) = ($77.25/day)d + ($0.12/mile)m ≤ $330. Substitute 1 for d (that is, the rental is for 1 day) and 175 for m:
R(d) = ($77.25/day)(d days) + ($0.12/mile)(175 miles) ≤ $330
= $77.25d + $21 ≤ $330
This simplifies to $77.25d + $21 ≤ $330, or
$77.25d ≤ $309
Solving this by dividing both sides of the above equation by $77.25, we get
d = ($309)/($77.25) = 4

Olivia is making bead bracelets for her friends. She can make 3 bracelets in 15 minutes.Find the constant of proportionality in terms of minutes per bracelet.
Answer:
The constant of proportionality is 5 minutes per bracelet
Step-by-step explanation:
If x and y are proportion, then y = k x, where
k is the constant of proportionalityWe can find k by dividing y by x ⇒ k = [tex]\frac{y}{x}[/tex]Let us solve our question
∵ Olivia is making bead bracelets for her friends
∵ She can make 3 bracelets in 15 minutes
We need to find the constant of proportionality in terms of minutes per bracelet, which means y represents the minutes and x represents the bracelet
∴ y = the time in minutes
∴ x = the number of bracelets
∵ y proportion with x
∴ k = [tex]\frac{y}{x}[/tex]
∵ y = 15 and x = 3
∴ k = [tex]\frac{15}{3}[/tex]
∴ k = 5
∴ The constant of proportionality is 5 minutes per bracelet
find the percentage increase in area of a triangle if its each side is doubled
First of all, to find the area of a triangle you multiply the base * height and divide the result by two (2).
Let's use a triangle which sides are all 2 inches. To find the area, you do 2*2/2 which equals 2.
Now, double each side and each side of the triangle is now 4.
We do 4*4/2 which now equals 8.
The percentage increase from 2 --> 8 is 600%.
The percentage of the old area to the new area is 800%
ANSWER: 600%

Solve for x in the following numbers
4x squared + 1 =4x
Answer: x = 1/2
Step-by-step explanation: Set it equal to zero by subtracting 4x from both sides:
4x² - 4x + 1 = 0
Now, factor it:
(2x - 1)(2x - 1)
Set each one equal to zero, but since they’re the same, you only need to do it once:
2x - 1 = 0
Add 1 to both sides:
2x = 1
Divide both sides by 2:
x = 1/2
Hope this helps!
Answer:
x=1/2
Step-by-step explanation:
4x^2+1=4x
or,4x^2-4x+1=0
or,(2x)^2 - 2*2*x+(1)^2 =0
or,(2x-1)^2 =0
or,2x-1 =0
or,2x=1
Therefore, x=1/2

Examplelt: A wall of length 10 m was to be built across an open ground. The height of the wall is 4 m and thickness of the wall is 24 cm. If this wall is to be built up with bricks whose dimensions are 24 cm x 12 cm x 8 cm, how many bricks would be required?
Answer :
4167 bricks.Explanation :
Since the wall with all its bricks makes up the space occupied by it, we need to find the volume of the wall, which is nothing but a cuboid.
Here,
[tex]{\qquad \dashrightarrow{ \sf{Length=10 \: m=1000 \: cm}}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{Thickness=24 \: cm}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{Height=4 m=400 \: cm}}[/tex]
Therefore,
[tex]{\qquad \dashrightarrow{ \bf{Volume \: of \: the \: wall = length \times breadth \times height}}}[/tex]
[tex]{\qquad \dashrightarrow{ \sf{Volume \: of \: the \: wall = 1000 \times 24 \times 400 \: {cm}^{3} }}}[/tex]
Now, each brick is a cuboid with Length = 24 cm, Breadth = 12 cm and height = 8 cm.
So,
[tex]{\qquad \dashrightarrow{ \bf{Volume \: of \: each \: brick = length \times breadth \times height}}}[/tex]
[tex]{\qquad \dashrightarrow{ \sf{Volume \: of \: each \: brick = 24 \times 12 \times 8 \: {cm}^{3} }}}[/tex]
So,
[tex]{\qquad \dashrightarrow{ \bf{Volume \: of \: bricks \: required = \dfrac{volume \: of \: the \: wall}{volume \: of \: each \: brick} }}}[/tex]
[tex]{\qquad \dashrightarrow{ \sf{Volume \: of \: bricks \: required = \dfrac{1000 \times 24 \times 400}{24 \times 13 \times 8} }}}[/tex]
[tex]{\qquad \dashrightarrow{ \sf{Volume \: of \: bricks \: required = \bf \: 4166.6} }}[/tex]
Therefore,
The wall requires 4167 bricks.A video game that usually costs $30.65 is marked down 60%. Kelvin determined that the new price of the game would be $18.39. Look at Kelvin’s work and find his error.

(Please also tell me the "Amount earned for 10. hours of work")
PLEASE ANSWER THIS I NEED HELP!!!
The total amount earned in 10 hours of work is $390.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, an independent contractor he charges a $140 fee plus $25 per hour for each contract with the city.
Here, y represents the total amount he changes for a project and x represents the number of hours worked on a project.
Now, y=140+25x
Amount earned for 10 hours of work is
y=140+25×10
= 140+250
= $390
Therefore, the total amount earned in 10 hours of work is $390.

You have a new pool and want to know its volume. The pool is 5 feet deep and has a radius of 7 feet. About how much water can the pool hold?
Answer:
Vol = 769.7 cubic ft
Step-by-step explanation:
"radius" is the distance from the center of a circle to the circle. So let's assume your pool is a circular pool with radius = 7ft and height = 5ft. It's a cylinder.
Volume of a cylinder:
Vol =
Base area•height
= pi•r^2 • h
= pi(7)^2•5
= pi•49•5
= pi • 245
= 245pi
Now, 245pi cubic ft is a perfectly good answer. But your teacher/text/class, may be asking for a decimal approximation.
If you use calculator pi (that's a lot of decimals) you get
Vol ~= 769.69 (to the hundredths place)
Vol ~= 769.7(to the tenths place)
If you were told to use 3.14 for pi
then you get
Vol ~= 769.3 cubic ft
But if you were told to convert units to gallons or liters there are more calculations (message, i can edit in these)
