Answer:
For a, the machine depreciates 20% of its current value each year. So, It will lose 20% of its value in the first year. Then in the second year, it will lose 20% of THAT value (not of the original value) and so on.
b) Since the machine loses 20% of its value each year, it retains 80% of its value each
A group of 106 campers sits in a big circle. The camp leader tells them to say "hello" to each camper sitting to their left and right. What is the total number of times the campers say "hello"?
Given :
A group of 106 campers sits in a big circle.
The camp leader tells them to say "hello" to each camper sitting to their left and right.
To Find :
What is the total number of times the campers say "hello".
Solution :
It is given that each camper say "hello" to each camper sitting to their left and right i.e each camper says "hello" twice.
Therefore, 106 campers will say hello = 106 × 2 = 212 times.
Hence, this is the required solution.

A baby is weighed on a defective scale. He weighed 28 pounds according to the scale. He weighs 25 pounds on an effective scale. What is the percent error?
Answer:
10.7%Step-by-step explanation:
Step one:
given
expected weight= 28pounds
Actual weight= 25 pound
Required:
percent error
[tex]\delta = \left| \frac{v_A - v_E}{v_E} \right| \cdot 100\%[/tex]
δ= percent error
vA =actual value observed
vE =expected value
δ=25-28/28*100
δ=-3/28*100
δ=0.107*100
δ=10.7%
The percent error is 10.7%

You are traveling in a car and you want to know how long it will take you to reach your destination. You will travel 220 miles at an average speed of 55 miles per hour. Use the distance formula D=r•t , to determine how much time, t, in hours it will take you to get there
Answer:
You will get there in 4 hours
Step-by-step explanation:
Use the distance formula D=r•t , to determine how much time, t, in hours it will take you to get there
Where D = Distance
r = rate = Average Speed
t = time in hours
From the question
D = 220 miles
t = ??
r = 55 miles/hour
Hence:
220miles = 55miles/hour × t
t = 220/55
t = 4 hours
You will get there in 4 hours
Marita's nose is 2 inches long and her head is 9 inches tall. Assume Mount Rushmore was carved using the same ratio. If Teddy Roosevelt's head is 60 feet tall, how long should his nose be? Round to the nearest foot, if necessary.
Answer:
13 1/3
Step-by-step explanation:
So the question is Marita's nose is 2 inches long and her head is 9 inches tall. Assume Mount Rushmore was carved using the same ratio. If Teddy Roosevelt's head is 60 feet tall, how long should his nose be? Round to the nearest foot, if necessary.
First divide 60 by 9 to figure out the first part of the ratio. So that is 60/9 or 6 2/3.
Then multiply 2 by 6 2/3 which is 13 1/3.
Finally when rounded to the nearest foot, it will be 13.

Enter your answer as a decimal in the box.
units
Answer:
Perimeter of rectangle is 23.34
Step-by-step explanation:
The coordinates of the vertices of a rectangle are (-4, 3), (-1, 5),(3, – 1), and (0, – 3).
What is the perimeter of the rectangle?
The formula to find perimeter of rectangle is: [tex]Perimeter=2(l+w)[/tex]
We need to find length and width first using the coordinates (-4, 3), (-1, 5),(3, – 1), and (0, – 3).
Let A=(-4, 3) B=(-1, 5) C=(3, – 1) and D=(0, – 3) according to the figure attached.
So, If we find distance of point AB it can be considered length of rectangle and distance of point AC can be considered width of rectangle
The formula used to find distance is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Finding distance AB, we have [tex]x_1=-4, y_1=3, x_2=-1, y_2=5[/tex]
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-1-(-4))^2+(5-3)^2}\\Distance=\sqrt{(-1+4)^2+(5-3)^2}\\Distance=\sqrt{(3)^2+(2)^2}\\Distance=\sqrt{9+4}\\Distance=\sqrt{13}\\Distance=3.61[/tex]
So distance between point A and B is 3.61
Finding distance AC, we have [tex]x_1=-4, y_1=3, x_2=3, y_2=-1[/tex]
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(3-(-4))^2+(-1-3)^2}\\Distance=\sqrt{(3+4)^2+(-1-3)^2} \\Distance=\sqrt{(7)^2+(-4)^2} \\Distance=\sqrt{49+16} \\Distance=\sqrt{65}\\Distance=8.06[/tex]
So, distance between point A and C is 8.06
We have length = 3.61 and width = 8.06
Using formula of perimeter
[tex]Perimeter=2(l+w)\\Perimeter=2(3.61+8.06)\\Perimeter=2(11.67)\\Perimeter=23.34[/tex]
So, Perimeter of rectangle is 23.34

Ferrell has 9 nickels and some quarters in his pocket. The value of his coins is $3.70. Which equation can be used to find the number of quarters, q, Farrell has in his pocket?
Answer:
[tex]0.45 + 0.25q = 3.70[/tex]
Step-by-step explanation:
Given that:
Number of nickels with Ferrell = 9
Number of quarters = [tex]q[/tex]
Value of coins = $3.70
To find:
The equation to find the number of quarters.
Solution:
Value of a nickel = 5 quarters = $0.05
Value of 9 nickels = [tex]9 \times 0.05 = \$ 0.45[/tex]
Value of a quarter = $0.25
Value of [tex]q[/tex] quarters = $0.25[tex]q[/tex]
Total value of coins = Value of 9 nickels + Value of [tex]q[/tex] quarters[tex]\$0.45 + \$0.25q = \$3.70\\\Rightarrow 0.25q=3.70-0.45\\\Rightarrow 0.25q=3.25\\\Rightarrow q =13[/tex]
So, the answer is, number of quarters available with Ferrell = 13
The equation to be used to find the number of quarters, [tex]q[/tex]:
[tex]0.45 + 0.25q = 3.70[/tex]

-9(m+3) +14=-49 please show work
Answer:
m=4
Step-by-step explanation:
−9(m+3)+14=−49
Step 1: Simplify both sides of the equation.
−9(m+3)+14=−49
(−9)(m)+(−9)(3)+14=−49(Distribute)
−9m+−27+14=−49
(−9m)+(−27+14)=−49(Combine Like Terms)
−9m+−13=−49
−9m−13=−49
Step 2: Add 13 to both sides.
−9m−13+13=−49+13
−9m=−36
Step 3: Divide both sides by -9.
−9m
−9
=
−36
−9
m=4

Complete the square for the expression. Also, identify the resulting expression as a binomial squared.
x2 + 11x + ____
When completing the square is carried out on the quadratic [tex]x^2+11x[/tex] we get
[tex]x^2+11x+\dfrac{121}{4}[/tex]
when expressed as a binomial squared, we get
[tex]\left(x+\dfrac{11}{2}\right)^2[/tex]
To complete the square, we need to add a term to the expression
[tex]x^2+11x[/tex]
that would make it a perfect square. Generally, given the quadratic expression
[tex]x^2+bx[/tex]
to make it a perfect square, we have to add half the square of the coefficient of [tex]x[/tex]. That is, add [tex]\left(\frac{b}{2}\right)^2[/tex], or [tex]\frac{b^2}{4}[/tex] to the quadratic expression to get
[tex]x^2+bx+\dfrac{b^2}{4}[/tex]
which, when factored into a binomial squared becomes
[tex]\left(x+\dfrac{b}{2}\right)^2[/tex]
In our case, the quadratic [tex]x^2+11x[/tex] will become
[tex]x^2+11x+\dfrac{121}{4}[/tex]

Step-by-step explanation:
Find the y-intercept you will always find it on the y axis (in this case it is 4)
the slope is -4/3 because you go down 4 times (Going down is negative up is positive) and right 3 times (Right is positive and left is negative)
Slope= rise/run
