Fred's age is 82.
Amanda's age is 27.
Catherine's age is 14.
Blake's age is 12.
The equation that represents Fred's age is: 1 + 3x =
Where x is Amanda's age
Fred and Amanda's age : 109 = 1 + 3x + x
4x + 1 = 109
4x = 109 - 1
4x = 108
x = 108 / 4
x = 27
Fred's age = 1 + (3 x 27) = 82
The equation that represents Blake's age is: b = 2c - 16
Where: b = Blake's age
c = Catherine's age = 2 + b
b = 2(2 + b) - 16
b = 4 + 2b - 16
16 - 4 = 2b - b
12 = b
Catherine's age = 12 + 2 = 14

Segment MP is a diameter of circle O.
Circle O is shown. Line segment M P is a diameter. Line segment N O is a radius. Angle N O P is 150 degrees.
Which equation can be used to find mArc M N?
mArc M N – 150 = 360
Answer:
[tex]arc\ MN + 150 = 180[/tex]
Step-by-step explanation:
Given
[tex]\angle NOP = 150^\circ[/tex]
See attachment for circle O
Required
Find [tex]arc\ MN[/tex]
The sum of angles in a semi-circle is 180 degrees.
So:
[tex]arc\ MN + \angle NOP = 180[/tex]
This gives:
[tex]arc\ MN + 150 = 180[/tex]
Hence, the equation is: [tex]arc\ MN + 150 = 180[/tex]

A cable company uses the formula S = 20,000 (1 + 0.08)^y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.008) ^y?
Answer:
the expression above is
y = Subscribers after time t = S
a = Initial Subscribers =20,000
r = Growth rate = 0.08 = 8%
t = time in years = y
Step-by-step explanation:
A cable company uses the formula S = 20,000 (1 + 0.08)^y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.008) ^y?
The above question represents Exponential growth
Exponential growth formula =
y = a( 1 + r) ^t
Where:
y = Population after time t
a = Initial Population
r = Growth rate
t = time in years
S = 20,000 (1 + 0.08)^y
Hence, the expression above is
y = Subscribers after time t = S
a = Initial Subscribers =20,000
r = Growth rate = 0.08 = 8%
t = time in years = y

"The difference between the circumference and diameter of a wheel is 18cm. Find the radius of the wheel. Use 3.14 for Pi. Round to the nearest tenth."
Answer:
[tex]4.2\ \text{cm}[/tex]
Step-by-step explanation:
d = Diameter of wheel
The difference between the circumference and diameter of a wheel is 18 cm.
[tex]2\pi r-d=18\\\Rightarrow \pi d-d=18\\\Rightarrow d(\pi-1)=18\\\Rightarrow d=\dfrac{18}{\pi -1}\\\Rightarrow d=\dfrac{18}{3.14-1}\\\Rightarrow d=8.41\ \text{cm}[/tex]
The diameter of the wheel is 8.41 cm so the radius will be [tex]\dfrac{8.41}{2}=4.205\approx 4.2\ \text{cm}[/tex].

[tex]in triangle ABC, AB=7, BC=10, and the measure of angle B=80, to the nearest 10th, what is b[/tex]
Answer:
b = 11.0
Step-by-step explanation:
From the given properties of the triangle,
b = AC
Applying the cosine rule, we have;
[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] - 2acCos B
= [tex]10^{2}[/tex] + [tex]7^{2}[/tex] - 2(10 x 7) Cos 80
= 100 + 49 - 140 x 0.17365
= 149 - 24.311
= 124.689
b = [tex]\sqrt{124.689}[/tex]
= 11.1664
b = 11.0

Answer:
$3
Step-by-step explanation:
Since he’s leaving a 20% tip, we need 20% of 15.
To solve, multiply 20/100 (20%) by 15:
20/100*15 = 300/100 = 3
He will leave a $3 tip.
Answer:
$3
Step-by-step explanation:
To solve this problem, first, one must convert the percent of the tip to decimal form. This can be done by dividing the percent by 100. Then one will multiply this value by the total bill.
20% * 15
= 0.2 * 15
= 3

Answer:
4 8.95h + 10 < 115
Step-by-step explanation:
Answer: 4) 8.95h + 10 < 115
Step-by-step explanation:
We know the inequality will be equal to less than 115 since it states that the order was less than $115.
The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115
8.95h + 10 < 115
(h in the given equation is the amount of shin guards)
Find the area and the circumference of a circle with radius 2yd. Use the value 3.14 for pie and do not round your answer. Be sure to include the correct units in your answer
Answer:
circumference: 12.56 yd
area: 3.14(2 yd)² = 12.56 yd²
Step-by-step explanation:
The circumference formula is C = 2πr (pi, not pie), where r is the radius.
When r = 2 yd and π ≈ 3.14, the circumference is:
C = 2(3.14)(2 yd) = 12.56 yd

A cylinder has a volume of 36 cubic inches. What is the volume of a cone if it has the same radius and height as the cylinder?
Answer:
12 cubic inches
Step-by-step explanation:
volume of a cylinder= pi*r2*height
but we are given 36 as cylinder volume.
Therefore , 36 = pi*r2* height
r2*height = 36/pi, let call this equation 1
volume of a cone = pi*r2*height/3;
but from equation 1, r2*height =36/pi, substituting this value in volume of cone.
volume of cone= pi*(36/pi)/3 = 12 cubic inches

Rope packaged in 80-foot lengths
must be cut into 12-foot pieces to
do a certain job. If 28 such pieces
of rope are needed for the job, how
many packages of rope are needed?
(A) 4
(B) 5
(C) 6
(D) 7
(E) 28
Answer:
it would be 5
Step-by-step explanation:
any of the answer could have really worked (not 4 since that gives you less then what is needed) but in the end it would have been 5 because 5 leaves you with only 5.33 feet of rope left
80* any one of the four numbers (ex: 5) = your answer that you got (ex: 400)
then you divide that number by 28 (ex: 33.33) and if you want to go the extra mile then do the number that you got by dividing 28 minis the number of rope pieces needed
the whole thing >
80* 5 = 400
400/28 = 33.33
33.33- 28 = 5.33
hope this helps! :)

What is the distance between (2. 6) and (7, 6)
Answer:
5
Step-by-step explanation:
Hey There!
So first off the y values are the same so to find the distance between the two points all we have to do is subtract the largest x value from the smallest x value
7-2=5
Therefore the distance between the two points is 5
Answer: 5
Step-by-step explanation:
D = √(x₂ - x₁)² + (y₂ - y₁)²
x₁ =2 y₁ =6 x₂ =7 y₂ =6
D =√(7-2)² +(6-6)²
D=√(5)² +(0)²
D =√25
D=5
