Solve for a and b in the following circles:
B)
a а
b
82°
Answer:
a 41
when the line touch the circle you have to take the half of it
for b its equal 144
the full circle degree is 360
so we can say the 82+2x=360
because the two lines in the circle equal each other so its means tha the Piece of the circle in the left is equal b too
hopefully its helpful and sorry because of my engilish

A box contains 95 pink rubber bands and 90 brown rubber bands. You select a rubber band at random from the box. Find each probability. Write the probability as a fraction in simplest form.
Find the theoretical probability of selecting a pink rubber band.
Answer:A. The theoretical probability for pink is 95/185 or about 51.35%
B. The theoretical probability for brown is 90/185 or about 47.82%.
C. To find the experimental probability, we will make another fraction. The number of outcomes will be the numerator and the total will be the denominator.
Pink 36/69 = 52.17%
Brown 33/69 = 47.82%

All lines are congruent to one another.
Answer:
This is false. Lines will be congruent if they have the same length, which is not the case in all situations.
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.
A diagram of a coin is shown.
10.5 mm
What is the approximate circumference of the coin? Use 3.14 as an estimate for it.
O A 21 mm
O B. 33 mm
O c. 66 mm
O D. 84 mm
Answer:
66mm
Step-by-step explanation:
A diagram of a coin is shown.
Radius = 10.5 mm
The approximate circumference of the coin is calculated using the formula
2πr
Use 3.14 as an estimate for it.
r = 10.5mm
Hence:
2 × 3.14 × 10.5
= 65.94
Approximately = 66mm
O A 21 mm
O B. 33 mm
O c. 66 mm
O D. 84 mm

The graph below plots the values of y for different values of x:
What does a correlation coefficient of 0.25 say about this graph?
x and y have a strong, positive correlation
x and y have a weak, positive correlation
x and y have a strong, negative correlation
x and y have a weak, negative correlation
Answer:
the answer is x and y have a weak, positive correlation.
Step-by-step explanation:
if a correlation is strong, it will either be close to 1 or -1 and the further in the decimal, the weaker the correlation becomes. the correlation is positive so that’s how I got the positive.

Answer:
d = 17.58
Step-by-step explanation:
d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(8, 7, 14)
Substitute the values in the above equation and you will get
d = √(8 - 0)^2 + (7 - 0)^2 + (14 - 0)^2
= √(64 + 49 + 196)
= √309
= 17.58
Answer:
The answer is 17.58
A laptop computer is purchased for $2000. After each year, the resale value decreases by 25%. What will the resale value be after years?
Use the calculator provided and round your answer to the nearest dollar.
$[]
Answer:
2000? ... assume $2000
Resale Value = $2000*(1 - 0.25)t/yr
where: t = number of year after purchase
at t = 3 yr
Resale Value = $2000*(1 - 0.25)3 = $843.75
checking: at t = 0 $2000 (purchase price)
at t = 1 yr $2000 - 0.25*$2000 = $2000 - $500 = $1500
at t = 2 yr $1500 - 0.25*$1500 = $1500 - $375 = $1125
at t = 3 yr $1125 - 0.25*$1125 = $1125 - $281.25 = $843.75

Is
X 10 11 12
Y 18 18.6 19.2 proportional or non proportional
Given:
The table of values.
To find:
Whether the given table is a proportional or non proportional relation.
Solution:
If y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
Where, k is the constant of proportionality.
Find the value of k for each ordered pairs in table. If the value of k is constant, then the relation is proportional.
The ordered pairs from the table are (10,18), (11, 18.6), (12,19.2). The values of k for each ordered pair is:
[tex]\dfrac{18}{10}=1.8[/tex]
[tex]\dfrac{18.6}{11}\approx 1.69[/tex]
[tex]\dfrac{19.2}{12}=1.6[/tex]
Since the value of k is not constant, therefore the given table represents a non proportional relationship.

Noah buys 3 packages of pens each package has four blue pens and two black pens which equation can be used to find p
Answer:
p = 3*[ 4p+ 2p]
Step-by-step explanation:
Total number of pens = 3 times [ 4 blue pens + 2 black pens]
If we denote the total number of pens by p then the equation becomes
p = 3*[ 4.blue + 2black]
p = 12p+6p
p = 18p
There are total 18 pens out of which 12 pens are blue and 6 pens are black.
You are buying six hats and have a coupon for 15 dollars off. You spend $45. How much is each hat?
Answer:
$10
Step-by-step explanation:
6x-15=45
+15. +15
6x=60
/6. /6
x=10
Answer:
$7.5¢ or [tex]7\frac{1}{2}[/tex]
Step-by-step explanation:
Do not use This solution:
Firstly, lets find how much the hats cost initially before the 15% coupon. To do that, divide, not multiply, divide $45 by 15% because 15% off means multiply 15% from the original price. But in this case we need to find the initial amount before the 15% coupon.
15% = [tex]\frac{15}{100}[/tex]
Now, set it up;
[tex]\frac{15}{100}[/tex] ×[tex]\frac{45}{1}[/tex]

A soccer ball is kicked upward from the ground with a speed of 96 feet per second. Its height h, in feet, after t seconds is given by the equation h(t) = -16² +96t.
HCL many seconds will it take the soccer ball to reach its maximum height?
Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 96t[/tex]
Required
Seconds to attain maximum height
The maximum of a quadratic function [tex]y = ax^2 + bx + c[/tex] is calculated using:
[tex]x = -\frac{b}{2a}[/tex]
So, we have:
[tex]t = -\frac{b}{2a}[/tex]
Where:
[tex]a = -16[/tex] and [tex]b = 96[/tex]
So:
[tex]t = -\frac{96}{2 * -16}[/tex]
[tex]t = -\frac{96}{-32}[/tex]
Cancel out negatives
[tex]t = \frac{96}{32}[/tex]
[tex]t = 3[/tex]

138+y=180
y=180-138
y=42
Answer:
Step-by-step explanation:
In the lower triangle, the top angle is also 90 degrees, so just add 90 +48 = 138 and subtract from 180. Y= 42 degrees.

All of the letters of MISSISSIPPI are put in a bag. What is the probability of selecting an M and then after not replacing the letter, selecting a P?
Answer:
2/110
Step-by-step explanation:
Picking the letter M is 1/11 because there is 1 letter M in the 11 letters of the word.
Selecting a P is 2/10 because there are 2 letter P's in the 10 letters( Letter M was taken out)
Multiply the 2 fractions
1/11 x 2/10 = 2/110

The solid below was made by cutting a cone-shaped hole out of a cylinder. The surface area of the resulting composite solid is square cm. Write your answer in terms of pi.
*see attachement below for the diagram
Answer:
(252π + 20) cm²
Step-by-step explanation:
The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)
✔️Curved surface area of cylinder = 2πrh
r = ½(12) = 6 cm
h = 18 cm
C.S.A = 2*π*6*18 = 216π cm²
✔️Area of 1 base = πr²
r = ½(12) = 6 cm
Area = π*6²
Area = 36π
✔️Slant height of the cone = 10 cm
✅The surface area of the resulting solid = 216π + 36π + 2(10)
= (252π + 20) cm²
