Answer:
A) <SQT = 36 degrees
B) <QRW = 36 degrees
C)<PRV = 72 degrees
Step-by-step explanation:
A) <SQT = 36 degrees (< SQT and < PQR are vertically opposite angles, and vertically opposite angles are equal)
B) <QRW = 36 degrees ( <QRW and < SQT are corresponding angles since they lie on the same side of the transversal across the parallel lines. Corresponding angles are equal)
C)<PRV = 72 degrees( <PRV is the exterior base angle to < PQR and exterior base angles, are always twice their interior correxpondents)

Step-by-step explanation:
Last year, a rapper performed 40 times. This year the rapper performs 125% of that number of times.
The number of times the rapper performed this year given the number of times he performed last year is 90.
How many times did he perform this year?Percentage is the fraction of an amount expressed as a number out of hundred. Percentage is a measure of frequency.
The number of times he performed this year = (1 + percentage) x number of times he performed last year
(1 + 1.25) x 40 = 90

Answer:
Distance between points (2, 1) and (8,9) is 10.
Step-by-step explanation:
let me know if you need an explanation :)
hope this helps and is right. p.s i really need brainliest :)
Answer:
10
Step-by-step explanation:
distance formula is the square root of x sub 1 - x sub 2 quantity squared +y sub 1 + y sub 2 quantity squared. In this case it would look like the square root of (8-2)^2 +(9-1)^2. this would simplify to the square root of 100, which is 10.

Evaluating Piecewise Functions:
Please explain your answer. Thank you.
Answer:
f(-1) is undefined.
Step-by-step explanation:
We are given:
[tex]f(x) = \left\{ \begin{array}{ll} -3x-11 & \quad x \leq -5\\ 2 & \quad x > 5 \end{array} \right.[/tex]
And we want to find f(-1).
The piecewise function only gives us values for x-values less than or equal to -5 or greater than 5.
Since -1 is fits neither of those conditions, it is not defined.
Our answer is undefined.

A rectangle has a length that is 3 more than the width. If the area of the rectangle is 28 units squared, what are the dimensions of the rectangle?
you can think this
WL = 28
L=3w + 8
W( 3W +8) = 28
3 W^2 + 8W + = 28
3W^2 + 8W -28 = 0 (1)
3 W^2 - 6 W + !4 W -28 =0-
3 W ( W - 2 ) + 14 ( W -2) =0
(3W+ 14) ( w-2) = 0
w = 2 L = 3(2) + 8 = 14 , then LW =28
ignore the negative answer of w = -14/3
If we write all factors of 28 { 2, 4 , 7, 14)
We see that 28 = 2 * 14 , 14 = 2* 3 + 8
Therefore we can have a rectangle with area of 28 units, with 2, 14 be its dimension , and have the
property of L = 2*3 +8 (

Hi Victoria,
Area=Length x width= 28 sq in
L=8+3w
So substitute that back into the equation:
Area = L x W
28 sq in = (8+3w) x w
28 sq in = 8w +3w2
28 sq in = w (8 + 3w)
Possible factors of 28 are 2 and 14 or 4 and 7, and 1 and 28. Substituting the possibilities in the equation, we find that the correct set of factors are 2 and (8 + 3*2) or 14.

1) A=LW = 28 in
2) L = 3W + 8
Substitute L = 28/W into the 2nd equation
28/W = 3W + 8
28 = 3W^2 + 8W
3W^2 + 8W - 28 = 0
(3W+ 14)(W - 2) = 0
Note that the answer must be positive therefore the second 'zero' is the answer

10n+0.3=0.1n+0.3 Solve for N
Answer:
n=0
Step-by-step explanation:
Let's solve your equation step-by-step.
10n+0.3=0.1n+0.3
Step 1: Subtract 0.1n from both sides.
10n+0.3−0.1n=0.1n+0.3−0.1n
9.9n+0.3=0.3
Step 2: Subtract 0.3 from both sides.
9.9n+0.3−0.3=0.3−0.3
9.9n=0
Step 3: Divide both sides by 9.9.
9.9n/ 9.9 = 0/ 9.9
n=0
Answer:
n=0
Answer:
0
Step-by-step explanation:
10n - .1n = 9.9n
9.9n + .3 = .3
subtract .3 from the other one and get 0
9.9n = 0 then divide and it comes out to 0

The surface area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for π. Round your answer to the nearest hundredth. A. 696.99 cm3 B. 133.97 cm3 C. 267.95 cm3 D. 334.94 cm3
Answer:
267.95cm^3
Step-by-step explanation:
S= 4πr^2
Surface area is 200.96
π= 3.142
200.96= 4×3.142×r^2
200.96= 12.57r^2
r^2= 200.96/12.57
= 15.99
= √15.99
r = 3.9
Volume= 4/3πr^3
= 4/3× 3.142×3.9^3
= 267.95 cm^3

Points A, B, C and D are on the circle. The ∠ACB and ∠ADB are angles subtended by the same arc AB. If arc AB measures (5x – 30)° and m∠ACB = (x + 15) °, what is m∠ADB?
Answer:
m∠ADB = 35°
Step-by-step explanation:
From the figure attached,
∠ACB and ∠ADB are the angles subtended by the same arc AB.
m(arc AB) = (5x - 30)°
m∠ACB = (x + 15)°
Since, "measure of an arc is double of the measure of the angle subtended by the arc at the circumference"
m(arc AB) = 2(m∠ACB)
(5x - 30) = 2(x + 15)
5x - 30 = 2x + 30
5x - 2x = 30 + 30
3x = 60
x = 20
By using theorem,
"Angles subtended by the same arc in the same segment of a circle are equal in measure"
Therefore, m∠ACB = m∠ADB
Since, m∠ACB = (x + 15)°
= 20 + 15
= 35°
m∠ADB = 35°
A number is between 40 and 45. It has prime factors of 2 and 7. What is the number?
Answer:
42
Step-by-step explanation:
42 is divisible by both 7 and 2
The number which has prime factors of 2 and 7 and in between 40 and 45 is 42.
Given that, a number is between 40 and 45. It has prime factors of 2 and 7.
What are prime factors?The process of writing a number as the product of prime numbers is prime factorization. Prime numbers are the numbers that have only two factors, 1 and the number itself.
The numbers between 40 and 45 are 41, 42, 43 and 44.
The factors of the numbers are as follows
41 = 1×41
42 = 1×2×3×7
43 = 1×43
44 = 1×2×2×11
Therefore, the number which has prime factors of 2 and 7 and in between 40 and 45 is 42.

What is the range of the years?
Answer:
6
Step-by-step explanation:
The range of a data set is the numbers covered by the data. This means that the range is the difference between the minimum and maximum. The minimum is the smallest point, 2, and the maximum is the largest point, 8. Therefore, since 8-2=6, 6 must be the range.
