Find the measure for
A)
127°
B)
131°
C)
135°
D)
139°
Answer:
B) 131°
Step-by-step explanation:
-4a + 139 = 4a + 123 because they are vertical angles
-4a + 139 = 4a + 123
reduce:
8a = 16
a = 2
4(2) + 123 = 131°
For the following rectangular prism, drag and drop the steps needed to find the volume in the correct order. Then type the volume in the last box. Not all pieces will be used.
Picture shown.
Answer:
Volume = 100 [tex]in^{3}[/tex]
Step-by-step explanation:
Volume, V= Bh
length = 10 inches
width = 5 inches
height = 2 inches
So that,
B = 5(10)
= 50 [tex]in^{2}[/tex]
B = 50 [tex]in^{2}[/tex]
Then,
V = (50)(2)
= 100
v = 100 [tex]in^{3}[/tex]

8. Identify the x and y intercept of the equation:
12x - 8y = 48
Answer:
X- intercept(S) : (4,0)
Y- Intercept(S) : (0, -6)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for Y.
Hopes this helps!
The x- intercept (4, 0) and y intercept ( 0, -6).
What is Intercept?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
when the independent variable is 0 and you want to know the value of the dependent variable (zero).
Given:
Equation: 12x - 8y = 48
Now, for x- intercept put y= 0
12x - 8(0)= 48
12x= 48
x= 4
and, for y- intercept put x= 0
12(0) - 8y= 48
-8y= 48
y= -6
Hence, the x- intercept (4, 0) and y intercept ( 0, -6).

Answer:
Volume of the larger one = 476.5625
Step-by-step explanation:
Remark
This is a terrific little problem. Thanks for posting. I hope the answer is still useful to you. If the cylinders are similar it means that r and h are multiplied by a constant when moving from the smaller cylinder to the larger one. Everything else, believe it or not, remains the same.
Equations
Surface area of the smaller cylinder = 2pi*r^2 + 2pi*r*h
Surface area of the larger cylinder = 2*pi*(kr)^2 + 2pi*(kr)*(kh)
Surface area of the larger cylinder = k^2 (2*pi*r^2 + 2pi* r*h)
Solution
Surface area of the larger cylinder = k^2 (2pi*r^2 + 2pi*r*h)
============================= ==================
Surface area of the smaller cylinder (2pi*r^2 + 2pi*r*h)
surface area of the larger cylinder = k^2
surface are of the smaller cylinder = 1
200 / 128 = k^2 / 1 Divide the top and bottom of the left by 8
25 / 16 = k^2 Take the square roots of both sides
sqrt(25/16) = sqrt(k^2)
5/4 = k
Now work on the volume.
The volume of the larger cylinder = pi (kr)^2 (kh) = k^3 * pi * r^2 h
The volume of the smaller cylinder = pi * r^2 h
The volume of the larger cylinder to the smaller one = k^3 = 1.953125
x / 244 = 1.953125 Multiply both sides by 244
x = 1.953125 * 244
x = 476.5625

If the value of y varies inversely with x , which function represents the relationship between x and y if y = 48 when x = 3?
A. Y= 144/x
B. Y= 16/x
C. Y= x/16
D. Y= x/144
Answer:
A. Y = 144/x
Step-by-step explanation:
Inversely means y = 1/x
If y = 48, when x = 3
so 144/3 = 48
Therefore the answer is A
If the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3
What is a function?A relation is a function if it has only One y-value for each x-value.
If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.
To find k, we can use the given values of y and x:
y = k/x
48 = k/3
k = 144
Now that we know k, we can write the function that represents the relationship between x and y:
y = 144/x
Therefore, if the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

Timothy spent 1 hour 22 minutes less than Bill reading last week. Bill spent 47 minutes less than Pete. Pete spent 3 hours reading. How long did Timothy spend reading?
Answer: 51 minutes
Step-by-step explanation:
Firstly, Pete spent 3 hours reading. Bill spent 47 minutes less than Pete reading so Bill spent:
= 3 hours - 47 minutes
= 2 hours 13 minutes
If Bill spent 2 hours 13 minutes reading and Timothy spent 1 hour 22 minutes less than this, the amount of time that Timothy read for was:
= 2 hours 13 minutes - 1 hour 22 minutes
= 51 minutes

Step-by-step explanation:
Casey recently purchased a sedan and a pickup truck at about the same time for a new business. The value of the sedan S, in dollars, as a function of the number of years t after the purchase can be represented by the equation S(t)=24,400(0.82)t. The equation P(t)=35,900(0.71)t2 represents the value of the pickup truck P, in dollars, t years after the purchase. Analyze the functions S(t) and P(t) to interpret the parameters of each function, including the coefficient and the base. Then use the interpretations to make a comparison on how the value of the sedan and the value of the pickup truck change over time.

Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.

Answer:
II) 78
Step-by-step explanation:
2x - 6 + 7x + 15 = 90
9x + 9 = 90
9x = 81
x = 9
<ABC:
7x + 15
7(9) + 15
78
Answer and Step-by-step explanation:
To find the measure of angle ABC, we need to find what x is first. We accomplish this by adding together the two angles and setting it equal to 90.
2x - 6 + 7x + 15 = 90
Combine like terms.
9x + 9 = 90
Subtract 9 from both sides.
9x = 81
Divide both sides by 9.
x = 9
We get x to be 9.
Now, we can plug this in for angle ABC.
7(9) + 15
Multiply 7 and 9 together.
63 + 15
Add 63 and 15 together.
78
The measure of ABC is 78.
That means the answer is II) 78.

Where does the graph of y = 4x + 24 intersect the x-axis?
Answer:
(-6, 0)
Step-by-step explanation:
y = 4x + 24
Plug y = 0
0 = 4x + 24
4x = - 24
x = - 24/4
x = - 6
So, the graph of y = 4x + 24 intersect the x-axis at (-6, 0)
Answer:
at point x= -6
Step-by-step explanation:
4x+24=0
4x=-24

Is 7 to the 8th power times 7 equivalent to 7 to the the third power times 7 to third power equivalent?
Answer:
They are not equivalent.
Step-by-step explanation:
Before we solve the question, we need to know that from the laws of indices:
A^x x A^y = A^(x+y).
7 to the power of 8th power means 7^8
7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.
7 to the power of 3rd power means 7^3
7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.
Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.
