Step-by-step explanation:
A school is building a rectangular stage for its chorus. The stage must have a width of 4 feet. The area of the stage must be at most 24 square feet. (These are rules of the local fire department.) Write an inequality that describes the possible lengths (in feet) of the stage.
Answer: Length ≥ 6 feet
Step-by-step explanation:
The area of a rectangle= length × width
In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.
The inequality that describes the possible lengths (in feet) of the stage would be:
Length × Width ≥ 24
Length × 4 ≥ 24
Length ≥ 24/4
Length ≥ 6
Therefore, the length must be at most 6 feet.

Sheets of Stickers
Cho is considering buying stickers by the sheet.
Four sheets cost $14.
How much would 11 1/2 sheets cost?
Guys plz help this is do tomorrow.
The cost of 11.5 sheets of stickers costs is $40.25.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, four sheets of stickers cost $14.
Now, the cost of 1 sheet of stickers is 14/4
= $3.5
The cost of [tex]11\frac{1}{2}[/tex] =11.5 sheet of stickers is
11.5×3.5
= $40.25
Therefore, the cost of 11.5 sheets of stickers costs is $40.25.

-3x-6=16
X = -7
X = 7.5
X = 3
X = -4
Answer:
-7
Step-by-step explanation:
Answer: x = 7.5
Step-by-step explanation:
first, i moved the constant to the right.
-3x = 16 + 6
then, i added the 16 and the 6.
-3x = 22
then, i divided both sides.
it answers out to x = -22/3, but, when made into n improper fraction, results as -7.5

translated 8 units down. Write an equation that could represent this function.
Using translation concepts, it is found that the equation is given by:
[tex]y = -3\sqrt[3]{x} - 8[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent cube root function is given by:
[tex]y = \sqrt[3]{x}[/tex]
It was reflected across the x-axis, that is, multiplied by -1, hence:
[tex]y = -\sqrt[3]{x}[/tex]
It was vertically stretched by a factor of 3, hence:
[tex]y = -3\sqrt[3]{x}[/tex]
Then, it was translated 8 units down, hence:
[tex]y = -3\sqrt[3]{x} - 8[/tex]

Quadrilateral QRST is a parallelogram. Determine the measure of QRS
Answer:
x=9
Step-by-step explanation:
In a parallelogram, opposite angles are equal.
So that means
2(3x - 4) = x + 37
6x - 8 = x + 37
5x = 45
x = 9
Answer:
x+37=2(3x-4) opposite angle of the parallelogram are equal
x+37=6x-8
37+8=6x-x
45=5x
x=9
the measure of QRS=2(3×9-4)=46

OAB is the sector of a circle, centre 0, with radius 8 cm and sector angle 30°.
BC is perpendicular to OA.
Calculate the area of the region shaded on the diagram.
Answer:
[tex]2.9 cm^2[/tex]
Step-by-step explanation:
Given,
Angle of sector = 30°
Radius of circle, r = 8 cm
Area of the shaded region, A =?
The diagram is attached below.
Now,
Area of shaded region = Area of sector - Area of triangle
Area of triangle = [tex]\frac{1}{2}\times base \times height[/tex]
We know that,
[tex]\sin \theta = \dfrac{P}{H}[/tex]
[tex]\sin 30^\circ= \dfrac{P}{8}[/tex]
[tex]P = \dfrac{8}{2}[/tex]
[tex]P = 4\ cm[/tex]
And
[tex]\cos \theta =\dfrac{B}{H}[/tex]
[tex]\cos 30^\circ = \dfrac{B}{8}[/tex]
[tex]B = \dfrac{8\times \sqrt{3}}{2}[/tex]
[tex]B = 4\sqrt 3[/tex]
Area of sector = [tex]\dfrac{\theta}{360^\circ}\times \pi r^2[/tex]
Area of sector = [tex]\dfrac{30^\circ}{360^\circ}\times \pi \times 8^2[/tex]
= 16.75 cm^2
Area of triangle = [tex]\dfrac{1}{2} \times 4\sqrt 3 \times 4[/tex]
= 13.85 cm^2
Area of shaded region = 16.75 - 13.85
= [tex]2.9 cm^2[/tex]

. A rectangular sheet of dimensions 33 cm x 24 cm is rolled into a cylinder so that the smaller side becomes the height of the cylinder. Find the volume of the cylinder so formed.
Answer:
[tex]V=2078.16\ cm^3[/tex]
Step-by-step explanation:
A rectangular sheet of dimensions 33 cm x 24 cm is rolled into a cylinder so that the smaller side becomes the height of the cylinder.
h = 24 cm
and the circumference of the cylinder, C = 33 cm
[tex]2\pi r=33\\\\r=\dfrac{33}{2\pi}\\\\r=5.25\ cm[/tex]
We need to find the volume of the cylinder so formed. The formula for the cylinder is given by :
[tex]V=\pi r^2h\\\\=\pi \times 5.25^2\times 24\\\\=2078.16\ cm^3[/tex]
So, the volume of the cylinder so formed is [tex]2078.16\ cm^3[/tex].

Determine the 8th term in the sequence defined by: A_n = 3 * 2^n-1
Answer:
384 but see below.
Step-by-step explanation:
Remark
A_n = 3*2^(n - 1) I will assume that's what you mean. I'll give the answer for A_n = 3*2^n - 1 as well.
Solution
n = 8
A_n = 3 *2^(8 - 1)
A_8 = 3*2^7
A_8 = 3* 128
A_8 = 384
If you mean A_n = 3*2^n - 1
Then you would get
A_n =3 * 2^8 - 1
A_8 = 3 * 256 - 1
A_8 = 768 - 1
A_8 = 767

Step 1: Define
20(x + 9) = 140
Step 2: Solve for x
Divide 20 on both sides: x + 9 = 7Subtract 9 on both sides: x = -2Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 20(-2 + 9) = 140(Parenthesis) Add: 20(7) = 140Multiply: 140 = 140Here we see that 140 does indeed equal 140.
∴ x = -2 is the solution to the equation.

Step-by-step explanation:
Question 3) there's 60 minutes in a hour
3 times 60 = 180 books in 1 hour
3 times 180 = 540 books in 3 hours
540 + 180 + 180 = 900 books in 5 hours
The difference between those numbers : 900-540= 360 and 540-180= 360 so every 2 hours 360 books is done each time so just add 360 books each time for every 2 hours added
Kathy needs money for a trip to Europe if she has US$300 in the bank but wants to withdraw half of it In British pounds and half of it into euros how many more euros and times with Havasu 1 pound equals 1.6 for US deep and one euro equals 1.3 to USD and round to the nearest whole
Answer: She has 21.63 more euros than pounds and has 1.23 times more euros than pounds.
Step-by-step explanation:
She has US$300, and she will withdraw half of it on pounds, and half of it in euros.
(half of US$300 is US$150)
We know that:
1 pound = US$1.6
(1 pound/US$1.6) = 1
Then US$150 = US$150*(1 pound/US$1.6) = (150/1.6) pounds = 93.75 pounds.
And we also know that:
1 euro = US$ 1.3
then:
(1 euro/US$ 1.3) = 1
This means that:
US$150 = US$150*(1 euro/US$ 1.3) = (150/1.3) euros = 115.38 euros.
This means that:
115.38 - 93.75 = 21.63
This means that she has 21.63 more euros than pounds.
and:
115.38/93.75 = 1.23
She has 1.23 times more euros than pounds.
