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]

If the area of a parallelogram is
120 ft.^2 and the base is 15 ft.,
what is the height?
Answer:
8 ft
Step-by-step explanation:
The area of a paralellagram is b*h. Since we know the base, 15, we can plug this into an equation.
15(h) = 120.
Divide by 15 on both sides to get you 8.

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 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
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

to find a shapes total amount of °, the equation is (n-2)x180°
(5-2)x180°

[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:
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)

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
