Answer:
C None of the above
Step-by-step explanation:
The expression
(5g+3h+4)⋅2
can be expanded using distributive property as follows:
5g⋅2 + 3h⋅2 + 4⋅2 =
= 10g + 6h + 8
option A expression
(5g+3h)⋅8
can be expanded using distributive property as follows:
5g⋅8+3h⋅8 =
= 40g + 24h
which is different from 10g + 6h + 8
Option B expression
(5g+3h)⋅6
can be expanded using distributive property as follows:
5g⋅6+3h⋅6 =
= 30g + 18h
which is different from 10g + 6h + 8

Answer:
Parallel
Step-by-step explanation:
AB is parallel to CD.
The supplementary angle to 97 is 83, so the lower right angle is 83 degrees.
We see that the upper left angle is 83 degrees and because these alternate interior angles are equal, the lines are parallel.
Answer:
AB is parallel to CD.
Step-by-step explanation:
The angle of inclination of AB and CD to the transversal are equal and of the same position.
The angle 97° of CD is corresponding to the same of AB

Which equation can be used to find the surface area of the cylinder?
r = 4 in.
h = 16 in.
S-2314) + 2(4x(16)
S=2x{8)2 + 2x{816)
S-23/16) + 2(16)(4)
S-214) + 2(9116)
Answer:
S = 2π(16) + 2π(4)(16)
or
S = 2(3.14)(16) + 2(3.14)(4)(16)
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of it bases and the lateral face. A cylinder has 2 circular base .
The surface area = area of 2 circular base + lateral face area
surface area = 2πr² + 2πrh
surface area = 2πr(r + h)
The surface area equation for a cylinder that has a radius as 4 inches and h as 16 inches can be represented using the formula below.
surface area = 2πr² + 2πrh
where
r = radius
h = height
r = 4 inches
h = 16 inches
S = 2π(4²) + 2π(4)(16)
S = 2π(16) + 2π(4)(16)
Assuming π was given as 3.14 the equation will be as follow
S = 2(3.14)(16) + 2(3.14)(4)(16)

2. In the diagram below, secants PT and PU have been drawn from exterior point P such that the four arcs
intercepted have the following ratio of measurements:
P
mRS : mST :MTU : mUR=1:4:4:3
R
(a) If mRS = x, then write an equation that could be used to solve for x
and find the value of x.
I
4
(b) State the measure of each of the four arcs.
mRS =
mST =
MTU
MUR =
Answer:
(a) x = 30°
(b) mRS = 30°
mST = 120°
mTU = 120°
mUR = 90°
Step-by-step explanation:
(a) In the picture attached, the diagram is shown.
Given that m arc RS = x, from the ratios:
m arc ST = 4x
m arc TU = 4x
m arc UR = 3x
The addition of the four arcs must be equal to 360°, then:
x + 4x + 4x + 3x = 360°
12x = 360°
x = 360°/12 = 30°
(b) m arc RS = x = 30°
m arc ST = 4x = 4*30° = 120°
m arc TU = 4x = 4*30° = 120°
m arc UR = 3x = 3*30° = 90°

Math problem: If the dimensions of a triangle are two times bigger, how does the area of the triangle change? (Hint: Draw this)
Answer:
The equation for area of a triangle is height multiplied by the base length, divided by 2. So, if the height is 2, and the base is 4, then you multiply the two together, making 8, and then divide it by 2, making the final area 4. So if the dimensions are doubled, then the equation would be 4 times 8 divided by 2. Which is 16. If we do this again with 16 times 8, we will get 128, which when divided by two is 64. This is 4 times 16, just as 16 is 4 times the original answer 4. This means that every time you double the dimensions you will get the original answer multiplied by 4.

I need this answer rn can anyone help?
Answer:
Your answer should be, B.
Step-by-step explanation:
So, we can identify this as a transversal, which I will assume you already know what that is. When you have a transversal, you need to follow a certain set of rules, and don't worry, they're very simple.
Angle PSR is a vertical angle of angle OST, which automatically, according to your theorems, postulates, or properties, equal to each other. So with that in mind, you know that STN follows the same rules.
Additionally, where the lines intersect, each corresponding side MUST equal 180 degrees. So to find MTS, all you have to do is 180 minus 73, which gives you 107, completing that line.
Hopefully this isn't confusing!
On a quiz there are four multiple-choice questions worth 3 points each and two true/false questions
worth 1 point each. Each multiple-choice question has five possible choices. If a student randomly
guesses on each question, what is the expected value of the student's score on the test?
2.8
5.4
3.4
1.8
Can anyone help me ples?
Answer:
3.4
Step-by-step explanation:
Answer:
3.4
Step-by-step explanation:
Since we have given that
Number of multiple choice question = 4
Number of true false questions = 2
Number of points for each multiple choice question = 3
Number of points for each true false question = 1
Number of choices in multiple choice = 5
Probability of getting correct answer in multiple choice question = 1/5
Probability of getting correct answer in true false question = 1/2
answer would be 17/5 which is equal to 3.4
Find the area of the polygon
Answer:
65
Step-by-step explanation:
You can split the polygon and find the area of the triangle STU and trapezoid SURO
Area of Trapezoid SURO: 49
Area of Triangle STU: 8*4/2= 16
49+16= 65
Answer:
65
Step-by-step explanation:
the area of the triangle is simply 8 times 4 divided by 2 which is 16
and the area of the trapezoid is 8+6/2 times 7 which is 49 and 49+16 is 65

The original price of a tractor was $55,000. The value decreases in value at a
steady rate of 11% per year. What will the tractor be worth in 8 years?
A) $21,651.24
B) $65,487.22
C) $45,591.35
D) $12,536.25
A) $21,651.24
Step-by-step explanation:x = p(1 - r)ⁿ
p = $55000
r = 11% = 0.11
n = 8 years
x = $55000(1 - 0.11)⁸
= $55000ₓ0.89⁸
= $55000ₓ0.39365888057
= $21651.24
Dan learned the mass of an electron is about 9.1×10⁻³¹ while the mass of a proton is about 1.7×10⁻²⁷. He thinks electrons have a greater mass than protons because 9.1 is greater than 1.7; Do you agree with him? How can you use scientific notation to compare the mass of an electron and a proton? Explain your thinking.

Marla is making a fence to go
all the way around the small
Flower garden she planted. The
garden is 5 feet long and 3 feet
wide. How many feet of fencing
does she need?
Answer:
16 feet of fencing
Step-by-step explanation:
This equation is essentially asking us the perimeter of the fence. If you add 5+3+5+3 you get the sum of 16
Answer:
16 feet
Step-by-step explanation:
She will need to the same amount of fencing as the measurement of her perimeter. To calculate the perimeter, you add length times 2 plus width times 2. 5x2+3x2=16, so the perimeter of the garden is 16 feet meaning she will need 16 feet of fencing :)

Does the equation below represent a
direct proportion? If yes, identify
the constant of proportionality.
3x + 4 =y
A. No
B. Yes, 4
C. Yes, 3
D. Yes, x
Answer:
Step-by-step explanation:
yes,4
Step-by-step explanation:
3x+4=y why is it no? Because if it has addition or subtraction in the equation then it does not have a constant of proportionality. If it is multiplication or division then it has a constant of proportionality.
Hope it helps!The length of the Earth’s equator is about 40,000 km, and the Earth’s diameter is 8/25 the length of the equator. What is the diameter of the Earth?
Answer:
See Below:
Step-by-step explanation:
40,000*8/25= the diameter, because the diameter is 8/25 of the equator which is 40000
Diameter= 40,000*8/25
Diameter= 12,800 km
Answer:
12,800 km
Step-by-step explanation:
Since the length of the Earth's equator is 40,000 km and the diameter is 8/25 the length of the equator, indicates that you would multiply 40,000 by 8/25, which gives you a product of 12,800, or, the diameter of the Earth which is 12,800 km.
