Answer:
60degrees
Step-by-step explanation:
For similar triangles, the angles of their angles are equal to matter the size.
Hence if triangle TRS is similar to triangle TMN, then;
<R = <M and <S = <N
Given that;
<T = 40 degrees
<R = 60degrees
<S = 80 degrees
Since <R = <M, then <M = 60degrees

If a circle is divided into 30 equal parts, what will be the measure of the angle of each part???
Answer:
12 degrees
Step-by-step explanation:
Total angle in a circle = 360 degrees
If a circle is divided into 30 equal parts
measure of each part = Total angle in a circle/Total parts
measure of each part = 360/30
measure of each part = 12 degrees
Hence the measure of each part is 12 degrees

If Alfie tosses the paper cup more times, what is the expected number of times that the cup will land on its side?
Question:
Alfie tossed a paper cup in the air 150 times and recorded the side it landed on.
Right side up = 60 Upside down = 53 Side = 37
If Alfie tosses the paper cup 100 more times what is the expected number of times the cup will land on its side?
Answer:
The expected number of times the cup will land on its side is 25 times
Step-by-step explanation:
Given
[tex]Right = 60[/tex]
[tex]Upside\ down = 53[/tex]
[tex]Side = 37[/tex]
Required
First, we calculate the probability of landing on side
[tex]P(Side) = \frac{n(Side)}{Total}[/tex]
[tex]P(Side) = \frac{37}{150}[/tex]
[tex]P(Side) = 0.247[/tex]
Next, we calculate the expected value; E(x) using:
[tex]E(x) = n * P(x)[/tex]
When tossed 100 more times:
n = 100 and P(x) = P(Side) = 0.247
So:
[tex]E(x) = 100 * 0.247[/tex]
[tex]E(x) = 24.7[/tex]
[tex]E(x) = 25[/tex] --- approximated
Hence, it is expected that it will land on its side 25 times

The point slope form of the equaton of the line that passes through (-9, -2) and (1, 3) is y-3=1/2(x-1). What is the slope-intercept form of the equation for this line?
Answer: y=1/2x+5/2
Step-by-step explanation:
y-3=1/2 (x-1)
y-3(-3)=1/2x-1/2(+3)
y=1/2x-1/2+6/2
y=1/2x+5/2

If pears cost $0.65, how many pears could you buy if you have $5.20 to spend? Write the equation you would use to answer the question. also, how was you alls day?
Answer:
0.65x = 5.20, 8 pears
Step-by-step explanation:
We put x beside 0.65 because that is the unknown number of pears we can buy with $5.20. To find out how many pears you could buy, we just solve for x. So let's do it!
0.65x = 5.20
x = 8
8 pears

What is Your Budget?
Task 2
Directions:
You are offered a job with a starting annual salary of $50,000 and two options for
determining your annual raise:
Option 1: An annual raise of $3,000 per year.
Option 2: A 5% raise each year.
The first one is done and the options for number four are:
w(2w+12)=160
2w^2+12w-260=0
2w^2+12w=260
w^2+6w-130=0
Answer:
Step-by-step explanation:
Part A
w² + 6w + c = 130 + c
w² + 2(3w) + c = 130 + c
To make left side of the equation a perfect square we will replace c by (3)².
w² + 2(3w) + 3² = 130 + c
[By formula → a² + 2ab + b² = (a + b)²]
w² + 2(3w) + 9 = 130 + 9
Therefore, c = 9 will be the answer.
Part B
From part A,
(w + 3)² = 139
Option (2) and Option (6) are the correct options.
Part C
w + 3 = √139
w = 11.79 - 3
w = 8.79
w ≈ 8.8 inches

Answer:
254.3
Step-by-step explanation:
The formula for the area of a circle is A = pi(r^2).
Shown in the picture is the diameter of the circle. To find the radius, or R, simply divide 18 by 2. The definition for a radius is basically half of the diameter.
Now...
3.14(9^2) = 254.34
Round to the nearest tenth: 254.3
write the equation of the line in fully simplified slope-intercept form??
Answer:
y=-2/3x+3
Step-by-step explanation:
(m)slope :rise over run
(b)y-intercept :where the line crosses the y axis
slope intercept for y=mx+b
4b+5=1+5b
Anyone know it ??
Answer:
b = 4
Step-by-step explanation:
4b+5=1+5b
1️⃣Rearrange terms
4b+5=1+5b
4b+5=5b+1
2️⃣Subtract 5 from both sides of the equation
4b+5=5b+1
4b+5-5=5b+1-5
3️⃣Simplify
4b=5b-4
4️⃣Subtract 5b from both sides of the equation
4b=5b-4
4b-5b=5b-4-5b
5️⃣Simplify
-b=-4
6️⃣Divide both sides of the equation by the same term
-b=-4 subtract -1
7️⃣Simplify
b=4
Answer: b=4
Done ✔
