What's the length of an arc with a central angle of 100° and a radius of 2 inches?
Answer:
3.49 inches
Step-by-step explanation:
circumference = 2(2)(π) = 12.56 inches
(100/360)(12.56) = 3.49 inches
Which dilation is shown by the graph?
Answer:
D. D₂ (∆XYZ)
Step-by-step explanation:
Dₙ = (x,y) → ((n)x, (n)y)
_________________
X = (-1, 2).
Y = (2, -1).
Z = (-2, -1).
_________
Dₙ ∆XYZ:
X(-1, 2) → X'(-2, 4)
Y(2, -1) → Y'(4, -2)
Z(-2, -1) → Z'(-4, -2)
______________
-2 / -1 = 2, 4 / 2 = 2.
4 / 2 = 2, -2 / -1 = 2.
-4 / -2 = 2, -2 / -1 = 2.
_______________
D₂ = (x,y) → ((2)x, (2)y).
X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)
Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)
Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)

These marbles are placed in a bag and two of them are randomly drawn what is the probability of drawing two yellow marbles if the first one is placed back in the bag befroe the second draw 2 yellow marbles,3 pink marbles, 5 blue marbles
Answer:
1/25
Step-by-step explanation:
Given :
Let :
Y = yellow marbles
P = pink marbles
B = blue marbles
Y = 2 ; P = 3 ; B = 5
Note : selection is done with replacement :
Probability = required outcome / Total possible outcomes
Total possible outcomes = (2+3+5) = 10
Probability of drawing 2 yellow marbles :
First Draw : P(yellow) = 2 /10 = 1/5
Second draw: P(yellow) = 2/10 = 1/5
Probability of drawing 2 yellow marbles :
1/5 * 1/5 = 1 /25

What are some real-world scenarios for the Pythagorean theorem?
Answer:
There are loads, but for example you can find the diagonal from a lamppost the the end of its shadow if you know the height of the post and the length of the shadow.

10 POINTS PLEASE HURRY
Answer:
Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry. When the circle is folded over a line of symmetry, the parts of the circle on each side of the line match up. This means that the parts of the circle on each side of the line must have the same area.

To find volume you multiply lwh
Answer:
2400 [tex]$cm^3$[/tex]
Step-by-step explanation:
From the triangle on the left, we can see that height is 15cm and from the triangle on the right, we can see that base is 8cm of the triangle, as both triangles are identical. So the area of the triangle is,
[tex]b = 8 cm\\h = 15cm[/tex]
[tex]A = \frac{1}{2}bh\\= \frac{1}{2}\times8\times15 cm^2\\= 60 cm^2[/tex]
The area of the prism should be the length of the prism times the area of the triangle. So it is [tex]60 cm^2 \times 40 cm = 2400 cm^3[/tex]

Answer:
x² - x - 6
Step-by-step explanation:
Given
(x + 2)(x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 3) + 2(x - 3) ← distribute parenthesis
= x² - 3x + 2x - 6 ← collect like terms
= x² - x - 6
Answer:
[tex]x^{2} -x-6[/tex]
it's quadratic

A political scientist asked a group of people how they felt about two political policy statements. Each person was to respond A (agree), N (neutral), or D (disagree) to each policy statement. a. Describe the sample space; that is, list all possible response combinations to the two statements. __________________________________________ b. Assuming each response combination in part (a) is equally likely, what is the probability the person being interviewed agrees with at least one of the two policy statements
Answer:
Sample space = (AA, AN, AD, NA, NN, ND, DA, DN, DD) ;
0.556
Step-by-step explanation:
Given :
Possible outcome of each policy statement = (A, N, D)
Number of statements = 2
Sample space = 3² = 9
Sample space = (AA, AN, AD, NA, NN, ND, DA, DN, DD)
Probability that a person agrees with atleast one of the 2 policy statements :
Probability = required outcome / Total possible outcomes
Required outcome = (AA, AN, AD, NA, DA) = 5
HENCE, P(person agrees with atleast one of the 2 policy statements) = 5 /9 = 0.556
Colin invests £1100 into his bank account.
He receives 5% per year simple interest.
How much will Colin have after 3 years?
Give your answer to the nearest penny where appropriate.
£
Answer:
Colin will have $1,265 after three years.
Step-by-step explanation:
First, we find the amount of interest Colin will have by using the following formula,
simple interest = principal * interest rate * time
now that we know the formula, we substitute the numbers in.
simple interest = $1,100 * 5% * 3
since the interest rate is obviously a percentage, we have to convert it into a decimal.
simple interest = $1,100 * 0.05 * 3
now that it is a decimal, we can solve this expression.
simple interest = $1,100 * 0.05 * 3
simple interest = $55 * 3 (here, we did $1,100 * 0.05 first so that it doesn't get confusing with all the numbers, it will be easier with two final numbers)
simple interest = $165
Colin has $165 simple interest but over here asks how much she will have AFTER 3 years. think about it, can you have $165 after having $1,100 in your bank AFTER 3 years? no, so we need to add the interest by the principal by using the following formula,
total amount = principal + simple interest
now, we substitute the numbers in.
total amount = principal + simple interest
total amount = $1,100 + $165
total amount = $1,265
Therefore, Colin will have $1,265 after 3 years.

Mary has completed 8 problems of her 20 question test. How much of the test has she completed in fraction form (simplity!)
O 8/20
O 4/10
O 1/2
0 2/5
Answer:
2/5
Step-by-step explanation:
She completed 8 out of 20 so we divide 8 by 20
8/20 can be simplified if we divide both the numerator and denominator by 4
which equals 2/5
Answer:
2/5
Step-by-step explanation:
8 divided by 20 gives you .4 which is 2/5

for what value of q is in the question -13(q+4)=7q+16
Answer:
q=-3 2/5
Step-by-step explanation:
First multiply -13 with (q+4)
-13q-52=7q+16
Now you have to change the order before = the numbers with q and after = the numbers without anything
-13q-7q=52+16
Remember that when you change positions the symbol too
Then solve it
-20q=68
Now u have to divide as i do
q=68/-20
you can simplify it
q=3 8/-20
Now divide by the greater divisor in this case is 4
q=3 2/-5
And organize it
q=-3 2/5
Never forget to do q=(answer)
Hopefully it helps.

A cone has a diameter of 10 inches and a depth of 20 inches. If you use the formula V=13πr2h to find the volume, will your answer be ≈523.6 inches3?
Please help
Answer:
Yes, the answer would be 523.6
Step-by-step explanation:
Formula for Volume of a cone:
V = πr²(h/3)
r = d/2
10/2
r = 5
V = πr²(h/3)
V = π(5²)(20/3)
V = π(25)(20/3)
V = 523.6
V= u +at U=2 A=-5 T=1/2 Work out the value of v
Answer:
v =-1/2 hope it may help u
Step-by-step explanation:
v =u+at
v=2 -5/2
v=4-5/2
v=-1/2/2
Answer:
Step-by-step explanation:
Given
u = 2 , a = - 5 t = 1/2
Now
v = u + at
= 2 + (-5) * 1/2
= ( 4 - 5) /2
= - 1/2
