Answer:
V = 159 3/8 cm^3
Step-by-step explanation:
V = l*w*h
V = 8 1/2 * 5 * 3 3/4
Change to an improper fraction
V = 17/2 * 5 * 15/4
V =1275/8
Changing back to a mixed number
8 goes into 1275 159 times with 3 left over
V = 159 3/8 cm^3

You build a seahorse hotel that’s 6 inches wide and 12 inches tall. It has a volume of 864 cubic inches. What is the hotel’s length?
Answer:
864/(6*12)
864/72
12 = l
Answer:
Step-by-step explanation:
V = l * b * h
l = V/(b * h)
L = 864/(6*12)

The simplified form of the given expression (2ab/a⁻⁵b²)⁻³ is b³/8a¹⁸. The correct answer is option A.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given as follows:
(2ab/a⁻⁵b²)⁻³
= [(2ab) / (a⁻⁵b²)]⁻³
Use the negative exponent rule: a⁻ⁿ = 1/aⁿ and simplify the denominator
= [(2a.a⁵b) / (b²)]⁻³
Combine the coefficients 1 and 5 to get
= [(2a⁶) / (b)]⁻³
= 1/[(2a⁶) / b]³
= 1/[(2a⁶)³ / b³]
Cube the resulting expression to get
= b³/8a¹⁸
Therefore, b³/8a¹⁸ is the simplified form of (2ab/a⁻⁵b²)⁻³.
Hence, the correct answer is option A.

An angle measures 72° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
that would be 108
Step-by-step explanation: it's 108 b/c supplementary angle/ either of two angles whose sum is 180°.
Answer:
Let the angle be x .
Its supplementary = 180 - x
Given:
x = 180 - x - 72
2x = 108
x = 54
Other angle = 180 - 54 = 126
Find the 8th term in the sequence
-1/2, -1, -2, -4......
Answer:
-64
Step-by-step explanation:
geometric
equation
a1(r)^n-1
-1/2(2)^8
Given sequence is -1/2, -1, -2, -4,...
We get,
a1 = -1/2
r = 2
n = 8
So,
a8 = a.r^(n-1)
a8 = -1/2 * 2^(8-1)
a8 = -1/2 * 2^7
a8 = -1/2 * 128
a8 = -64
Therefore, 8th term of the sequence is -64

In ΔLMN, the measure of ∠N=90°, ML = 97, NM = 65, and LN = 72. What ratio represents the tangent of ∠L?
Answer:
The tangent of ∠L represents the ratio between side NM and side LN.
The value of this tangent is 0.9028
Step-by-step explanation:
The angle ∠N is 90°, so we have a right triangle. In a right triangle, the tangent of an angle represents the ratio between the opposite side of that angle and the adjacent side (the cathetus, not the hypotenusa) of that angle.
So, in the triangle LMN, the opposite side to the angle ∠L is NM, and the adjacent side is LN (ML is the hypotenusa, because it is the bigger side). The value of this tangent is:
tan(L) = NM / LN = 65 / 72 = 0.9028
Answer:
65/72

[tex]=31.64ft^2[/tex]
Step-by-step explanation:
Triangle

Semicircle
[tex]A=\frac{\pi r^2}{2}\\=\frac{\pi 2.5^2}{2} \\=9.82ft^2\\[/tex]
because both semicircle are the same just multiply by 2
[tex]9.82*2\\=19.64ft^2[/tex]
Now add all together
[tex]12+19.64\\=31.64ft^2[/tex]
Answer:
31.64 ft*2
Step-by-step explanation:
Break down the problems by shapes-
1. Triangle= 4 x 6/2
=12 ft*2
2. Semi-Circle= 2.5/2 (sense their are two, we only need to solve one)
=9.82 ft*2
Multiply 9.82 by 2
=19.64 ft*2
Adding all together

Answer:
a) 72 cm^2
b) 9 cm^2
c) 9 cm^2
d) 60.39 cm^2
Step-by-step explanation:
a) the the length is 12 cm and the width is 6 cm. Area = lw
A=(12)(6)
A=72 cm^2
b) base equals 3 cm
Height equals 6 cm
A=1/2(3)(6)
A= 9 cm^2
c) base = 3 cm
height=6 cm
Area=1/2(3)(6)
A=9 cm^2
d) to to find the area of the parallelogram, You need to use Pythagorean theorem for one of the triangles.
3^2 + 6^2 = x^2
9 + 36 = x^2
45=x^2
✓45 = ✓x^2
x = 6.71 cm
12-3 = 9
now that you have all the sides for the parallelogram, multiply 6.71 times 9 to get the area.

A model airplane is built at a scale of 1 inch to 6 feet. If the model plane is 8 inches long, how many feet long is the actual airplane?
Type your answer as a whole number in the box below.
_____ feet
The airplane is 48 feet long in real dimensions.
To find out how long the airplane actually is, we can use the scale and input our amount of inches that it is measured by.
So, 1 inch equals to 6 feet.
Our model plane is 8 inches.
Now, we plug it in.
8 inches = 6(8)
8 inches = 48 feet
Therefore, the length of the real airplane is 48 feet.
48 feet
Answer:
48 feet
Step-by-step explanation:
Let's create a proportion using the following setup.
inches/feet=inches/feet
We know the scale is 1 inch to 6 feet. We also know that the plane is 8 inches long, but we don't know how many feet long it is, so we can say x feet.
1 inch/6 feet= 8 inches/ x feet
1/6=8/x
Cross multiply. Multiply the numerator of the first fraction by the denominator of the second. Multiply the denominator of the first by the numerator of the second.
1*x=6*8
x=6*8
x=48
Add appropriate units, in this case: feet.
x= 48 feet
The actual airplane is 48 feet long.

A landscape architect is designing a pool that has this top view:
How much water will be needed to fill this pool 4 feet deep?
Answer:
546 ft³
Step-by-step explanation:
In the figure attached, the top view of the pool is shown. It can be decomposed into a trapezoid which height is 12 ft and which bases are 9 ft and 11 ft; and a rectangle which height is 1.5 ft and and it base is 11 ft.
Area of the trapezoid: (9 + 11)/2 * 12 = 120 ft²
Area of the rectangle: 1.5*11 = 16.5 ft²
Total area: 120 + 16.5 = 136.5 ft²
Volume of the pool: Total area * deep = 136.5 * 4 = 546 ft³
