A pyramid has a rectangular base of dimensions 15 cm and w cm. Given that its height and volume are 18 cm and 826 cm3 respectively, find the value of w.
Answer:
9.18 cm
Step-by-step explanation:
A pyramid is a three-dimensional object. The base of a pyramid is a polygon. the top and the base of a polygon forms a triangle.
for a rectangular pyramid, the base is a rectangle
The volume of a pyramid = 1/3 × (area of the rectangle x height)
Area of a rectangle = length x width
15 x w = 15w cm²
826 = 1/3 x (15w x 18)
multiply both sides of the equation by 3
15w x 18 = 2478
Divide both sides of the equation by 15 x 18
w = 9.18 cm
divide both sides by 10

From the top of a 100 ft air traffic control tower, an airplane is observed flying in at an angle of 32\displaystyle \degree°. If the airplane is 3000 feet away, what is the plane's altitude?
Answer:
1974.6 feets
Step-by-step explanation:
The plane's altitude is : h + 100 feets
To obtain h, according to the attached picture ;
We can use trigonometry :
Tan θ = opposite / Adjacent
Opposite = h ; adjacent = 3000 feets
Tan 32° = h / 3000
h = 3000 * 0.6248693
h = 1874.6080
Plane's altitude :
h + 100 feets
(1874.6080 + 100) feets
= 1974.6 feets
Is 1.58745078664 rational or irrational?
Thank you!
Answer: Rational
Step-by-step explanation:
1.58745078664 is rational
This is due to the fact that the number can be expressed with the ratio of two integers. If you were unable to do so, it would be irrational.

A rectangle has a base that is three feet longer than its height. The area of the rectangle is 54 square feet. What are the dimensions of the rectangle?
Answer:
h=6 feet
Step-by-step explanation:
Given: 1. The base of a rectangle is three feet longer than its height.
2.Are of the rectangle=54 square meters
Let us say the rectangle has height h and base(breadth) b.
Since, the base of the rectangle is three feet longer than the height, we have b=h+3.
Also, Area of the Rectangle= hb
therefore, 54=h(h+3)
54= h2+ 3h
h2+3h-54=0 (Subtract 54 from both the sides)
To find the value of h we have to solve the quadratic equation.
[We have the equation in the form ax2+bx+c=0, to factorise the equation-
Step1. Find two numbers such that their multiplication is equal to ac and their addition is equal to b.
Step2. Replace b with these numbers.
Step3. Simplify the equation]
So, h2+3h-54=0
h2+9h-6h-54=0
h(h+9)-6(h+9)=0
(h+9)(h-6)=0
Which gives-
h= -9 or h= 6
As h is the height of the rectangle, h can not be -9.
so h=6 feet
and b=h+3=9 feet
So the dimensions of the rectangle are 6 feet for the height and 9 feet for the base.
select all that apply.

Identify the radius, diameter, and height of each cylinder, Find the Volume.
Answer:
36pi cm^3 or 113.097 cm^3
Step-by-step explanation:
Diameter = 6
Radius = 3
Height = 4
Volume = pi * r^2 * h
pi(3)^2*4 = 36pi cm^3 or 113.097 cm^3
if the original parabola defined by y= x ^2, how would it change if y= 2 (x - 3) +1 were graphed instead?
Answer:
It would be stretched vertically by a factor of 2, shifted right 3, and shifted up 1
Step-by-step explanation:
Note that inside the parentheses, the shift is the opposite direction of the add/subtract sign.

A parallelogram has sides 17.3 m and 43.4 m long. The height corresponding to the 17.3-m base is 8.7 m. Find the height, to the nearest tenth of a meter, corresponding to the 43.4-m base.
Answer:
3.5m
Step-by-step explanation:
A parallelogram has sides 17.3 m and 43.4 m long.
The height corresponding to the 17.3-m base is 8.7 m.
The area of a parallelogram = base × height
= 8.7m × 17.3m
= 150.51m²
Both parallelograms have the same area
Hence, the height, to the nearest tenth of a meter, corresponding to the 43.4-m base is calculated as:
= 150.51m²/43.4m
= 3.4679723502m
Approximately = 3.5m

Find the area of the polygon. Please help.
Answer:
40 units
Step-by-step explanation:
The area of this rhombus can be broken up to four 4 by 5 right triangles, each having an area of 4*5/2=10, so the answer to your desired question is 10*4=40
Hey there!
The correct answer is 40 units squared.
We can solve this by breaking up the shape. There are four equivalent right triangles, so we can solve for one, and multiply it by 4! The area of a triangle is bh/2 or base * height / 2. So, we can set up the following equation:
(4 * 5) / 2 = area
20 / 2 = area
10 = area
Now we can multiply it by 4, which gives us 10 * 4 or 40.
Have a terrificly amazing day! :D

List the pairs of congruent angles and the extended proportion that relates the corresponding sides for the similar triangles. Plz this is due today!!!! I tried 3 times already!!!! More in pic.
9514 1404 393
Answer:
angle pairs: correctEF/HI = EG/HJ = FG/IJStep-by-step explanation:
As with the angle pairs, use the corresponding vertices to name corresponding segments.
As is done here, I find it convenient to list the vertices vertically in the order shown in the similarity statement.
∠E ≅ ∠H∠F ≅ ∠I∠G ≅ ∠JThis can make it easier to identify the corresponding vertices used for naming segments.
__
Moving on the the extended proportion, ...
The denominator HI uses the first two vertices, with E corresponding to H and F corresponding to I. The appropriate ratio is ...
EF/HI
The denominator HJ uses the 1st and 3rd vertices, with E (still) corresponding to H and J corresponding to G. The appropriate ratio is ...
EG/HJ
Similar thinking is used to identify the last ratio:
FG/IJ
Then the extended proportion is ...
EF/HI = EG/HJ = FG/IJ
Logan collected pledges for the charity walk-a-thon. He is receiving total contributions of $65 plus $20 for every mile he walks. How many miles will Logan need to walk in order to receive $325?
Answer:
Number of miles= 13
Step-by-step explanation:
Giving the following information:
He is receiving total contributions of $65 plus $20 for every mile he walks.
To calculate the number of miles to reach $325, we need to use the following formula:
Total collection= fixed contribution + variable contribution per mile*number of miles
325= 65 + 20*number of miles
260/20 = number of miles
number of miles= 13
