Answer:
D
Step-by-step explanation:
Given
C = 2πr ( isolate r by dividing both sides by 2π )
[tex]\frac{C}{2\pi }[/tex] = r → D
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°

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 :)
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.

Math question for brainliest
Answer:
D
Step-by-step explanation:
because you are looking for an intercept and an intercept is a square equation which when divided by 4 takes a slope. WHich then D works to make the slope
Answer:
y - 9 = 1/2(x - 8)
Step-by-step explanation:
The point slope form of the equation of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point
y - 9 = 1/2(x - 8)
2. Find the value of x. *

RE
24
Answer:
x=6
Step-by-step explanation:
3(x+2) = 24
Divide each side by 3
3/3(x+2) = 24/3
x+2 = 8
Subtract 2 from each side
x+2-2 = 8-2
x=6

Lindsay owns one-third the number of books that Destiny owns. Henry owns a fourth as many books as Destiny.
Together they own 57 books. If the equation -X+ x + x =57 models the scenario, how many books does Lindsay
3 4
own?
12
18
36
48
Answer:
12
step by step equation:
Lindsay owns 12 books.
Step-by-step explanation:
We can solve this question using a system of equations.
I am going to say that:
x is the number of books that Lindsay owns.
y is the nuber of books that Destiny owns.
z is the number of books that Henry owns.
Lindsay owns one-third the number of books that Destiny owns.
This means that:
, or
Henry owns a fourth as many books as Destiny.
This means that , or . Also, in function of x, we may have
Together they own 57 books.
This means that
We want to find x. So
Lindsay owns 12 books.

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

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

What is the answer in integer form?
Answer:
I believe it's $4
Step-by-step explanation:
If it's asking you for the integer in that scenario, the only integer there is $4.
An integer is any whole number, and 4 is a whole number, so I guess that's the answer.

Which triangle results from a reflection across the line x = 1?
Answer:
d
Step-by-step explanation:
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!
HEY GUYS I NEED HELP WIT THIS PLZ HELP ME??!! 20 points!!
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.

guesses on each question, what is the expected value of the student's score on the test?
2.8

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

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)

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
