Answer:
$1100
Step-by-step explanation:
First find the area of the trapezoid
A = 1/2 (b1+b2)*h
A = 1/2 ( 90+110) *44
A = 1/2(200)*44
A = 4400ft^2
The cost is .25 per square foot
4400* .25 =1100
Answer:
$1100
Step-by-step explanation:
((90 + 110)/2 * 44)) * .25 = 1100

1. A rectangular pyramid is intersected by a plane to create the frustum shown. If the height of the original pyramid is 14 m, what is the volume of the frustum?
10 m
4 m
8 m
6 m
12m
The volume of the frustum that is shown in the diagram is: C. 256 m³.
What is the Volume of Frustum?The volume of frustum = Volume of the bigger rectangular pyramid - Volume of smaller rectangular pyramid.
Find the volume of the original (bigger) rectangular pyramid:
Volume of rectangular pyramid = 1/3(lwh) = 1/3(12 × 6 × 14)
Volume of rectangular pyramid = 336 m³
Find the volume of the smaller (the top that was removed) rectangular pyramid:
Volume of rectangular pyramid = 1/3(lwh) = 1/3(10 × 4 × 6)
Volume of rectangular pyramid = 80 m³
The volume of frustum = Volume of the bigger rectangular pyramid - Volume of smaller rectangular pyramid = 336 - 80 = 256 m³.
Thus, the volume of the frustum that is shown in the diagram is: C. 256 m³.

What is the minimum Valium of this function? F(x)=150•sin(3•x)
A=150
B=-150
C=200
D=-200
Answer:
B -150.
Step-by-step explanation:
The minimum value of a sine is -1
So the answer is 15 * - 1 = -150.
Answer:
-150
Step-by-step explanation:
F(x)=150•sin(3•x)
The minimum that sin takes is negative 1
so 150(-1) = -150
The minimum of f(x) is -150
Gabby is touring New York City with her family. They want to visit the Empire State Building, Central Park, and Times Square before their dinner reservations at 8:25 P.M. They want to spend 1 hour and 10 minutes at the Empire State Building, 2 hours and 50 minutes in Central Park, and 1 hour in Times Square. What is the latest time Gabby's family can start their tour in order to make it to dinner on time?
Answer:
3:25 pm
Step-by-step explanation:
How much time do they need for tours
Empire State Building : 1 hour 10 minutes
Central Park 2 hour 50 minutes
Times Square 1 hour
-------------------------------
4 hours 60 minutes
but 60 minutes = 1 hour so subtract 60 minutes and add 1 hour
4 hours 60 minutes
+1 -60
--------------------------------
5 hours
They need 5 hours for the tours
We have to be at dinner at 8:25 so we need to start 5 hours earlier
8:25
- 5
------------------
3:25
We can start no later than 3:25 pm
Answer:
3.25
Step-by-step explanation:
First convert into minutes
1 hour = 60 minutes
Empire state building:
60 + 10 = 70
Central park:
60 + 60 + 50 = 170
Times square:
60
Now add all minutes together.
70 + 170 + 60 = 300 minutes.
Convert into hours:
300 / 60 = 5 hours.
8 - 5 = 3
So, Gabby's family can start their tour at 3:25 at most to get to dinner on time.

2. Write an equation that can be used to find M-Angle M. Then Solve it. Round to the nearest degree
Answer:
M = sin ^-1 (5/11)
M = 27 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin M = 5/11
Taking the inverse sin of each side
sin ^-1 sin M = sin ^-1 (5/11)
M = sin ^-1 (5/11)
M=27.03569
To the nearest degree
M = 27

Answer:
Sally is currently 4 years old.
Step-by-step explanation:
Kaden is 18 years older than Sally now. In 5 years, Kaden will be 3 times as old as Sally. How old is Sally now?
Let Kaden's current age be [tex]k[/tex] and Sally's current age be [tex]s[/tex]. We can write the following algebraic equation using the fact that Kaden is currently 18 years older than Sally:
[tex]k=s+18[/tex]
Next, we will use the fact that in 5 years, Kaden will be 3 times as old as Sally. If Kaden and Sally's current ages are [tex]k[/tex] and [tex]s[/tex] respectively, then their ages in 5 years will be [tex]k+5[/tex] and [tex]s+5[/tex] respectively. Therefore, we have:
[tex]k+5=3(s+5)[/tex]
We have two equations with two variables. To solve for either variable, we need to create an equation with only one variable. Therefore, let's substitute the first equation into the second:
[tex](s+18)+5=3(s+5)[/tex]
Distribute and combine like terms:
[tex]s+18+5=3s+15,\\s+23=3s+15[/tex]
Subtract [tex]s[/tex] from both sides, then subtract 15 from both sides:
[tex]8=2s[/tex]
Divide both sides by 2:
[tex]s=\frac{8}{2}=\boxed{4}[/tex]
Therefore, Sally is currently 4 years old.
Answer:
Sally is 4 years old now.
Step-by-step explanation:
Let Sally's age = x
Kaden's age = x + 18
In 5 years, they are both 5 years older than now.
Sally will be x + 5
Kaden will be x + 18 + 5 = x + 23
"In 5 years, Kaden will be 3 times as old as Sally."
x + 23 = 3(x + 5)
x + 23 = 3x + 15
-2x = -8
x = 4
Answer: Sally is 4 years old now.

Treat the matrices on the right side of each equation like you would a constant.
Let 2X + Y = A and 3X - 4Y = B.
Then you can eliminate Y by taking the sum
4A + B = 4 (2X + Y) + (3X - 4Y) = 11X
==> X = (4A + B)/11
Similarly, you can eliminate X by using
-3A + 2B = -3 (2X + Y) + 2 (3X - 4Y) = -11Y
==> Y = (3A - 2B)/11
It follows that
[tex]X=\dfrac4{11}\begin{bmatrix}12&-3\\10&22\end{bmatrix}+\dfrac1{11}\begin{bmatrix}7&-10\\-7&11\end{bmatrix} \\\\ X=\dfrac1{11}\left(4\begin{bmatrix}12&-3\\10&22\end{bmatrix}+\begin{bmatrix}7&-10\\-7&11\end{bmatrix}\right) \\\\ X=\dfrac1{11}\left(\begin{bmatrix}48&-12\\40&88\end{bmatrix}+\begin{bmatrix}7&-10\\-7&11\end{bmatrix}\right) \\\\ X=\dfrac1{11}\begin{bmatrix}55&-22\\33&99\end{bmatrix} \\\\ X=\begin{bmatrix}5&-2\\3&9\end{bmatrix}[/tex]
Similarly, you would find
[tex]Y=\begin{bmatrix}2&1\\4&4\end{bmatrix}[/tex]
You can solve the second system in the same fashion. You would end up with
[tex]P=\begin{bmatrix}2&-3\\0&1\end{bmatrix} \text{ and } Q=\begin{bmatrix}1&2\\3&-1\end{bmatrix}[/tex]

Find the area and perimeter of the shaded region below. Give your answer as a completely simplified exact value in terms of pi.
Answer:
23.73pi (rounded to the nearest hundredth)
Step-by-step explanation:
You can find the radius of the half-circle by looking at the triangle. You then calculate the area of a circle with that radius and divide the area by 2. Area of full circle=113.1
113.1/2=56.55. You must now calculate the area of the triangle, (6*6)/2. This gives you 18. Add your areas together, 56.55+18=74.55. Now divide your answer by pi. Then you put it as an equation of 74.55/pi = 23.73pi.
f(x) = 3x + 2; g(x) = 3x - 5
Find f/g. (1 point)
(f/g)(x) = Quantity three x minus five divided by three x plus two. ; domain {x|x ≠ - two over three }
(f/g)(x) = Quantity three x plus two divided by three x minus five. ; domain {x|x ≠ five over three }
(f/g)(x) = Quantity three x minus five divided by three x plus two. ; domain {x|x ≠ five over three }
(f/g)(x) = Quantity three x plus two divided by three x minus five. ; domain {x|x ≠ - two over three }
Answer:
f(x) / g(x) = (3x+2)/ (3x+5) x ≠-5/3
Step-by-step explanation:
f(x) = 3x + 2
g(x) = 3x - 5
f(x) / g(x) = (3x+2)/ (3x+5)
The denominator cannot equal zero
3x+5 ≠0
3x≠-5
x ≠-5/3
True or false: f(x) is a function
False because 5 is associated with two values.
To be a function, the domain can only map to one range value, but in this case, 5 is mapped to two values, 1 and 3.

(b) The force, F, between two objects is inversely proportional to the square of the distance, d, between
them.
The distance between two objects is increased by 20%.
Calculate the percentage reduction in the force between the objects.
Answer:
F is reduced by 31%
Step-by-step explanation:
F = 1/(d²)
now, we increase the distance by 20% (multiply by 1.2).
F new = 1/(1.2×d)² = 1/(1.44×d²) = (1/1.44) × (1/(d²)) =
= 1/1.44 × old F = 0.69 × old F
100 - 69 = 31%

If the ratio of raisins to bran flakes in a box of raisin bran flakes cereal is 3:27, how many raisins are there in a box that contains 3,000 raisins and brand flakes?
Answer:
300 raisins
Step-by-step explanation:
sum the parts of the ratio, 3 + 27 = 30 parts
Divide the total by 30 for the value of one part of the ratio.
3000 ÷ 30 = 100 ← value of 1 part of the ratio , then
3 parts = 3 × 100 = 300 ← number of raisins in a box

An angle measures 75.2° more than the measure of its complementary angle. What is the measure of each angle?
Answer:
x = complement
x + 5.2 = first angle (5.2 more than complement)
measure of two complementary angles add up to 90.
x + x+ 5.2 = 90
2x = 84.8
x = 42.4
other angle = x + 5.2 = 42.4 + 5.2 = 47.6
