In 1992, a postage stamp cost $0.25. In 2004, a postage stamp cost $0.37. What is the average rate of change in postage cents per year?
Answers
Answer: 0.01 (One cent per year)
Step-by-step explanation:
We need to find the price the stamp increased per year.
The difference in years is 12.
2004 - 1992 = 12
The difference in price is 0.12.
0.37 - 0.25 = 0.12
So to find price increase per year we do the following:
$0.12/12 = 0.01
$0.01 is one cent per year.

In the figure below, points D, E, and F are the midpoints of the sides of ABC. suppose DF =34, AC =48, and BC =78. find the following lengths.
Answers
For any given Triangle ABC, its medial triangle is constructed by finding the midpoints of its three sides (Segments AB, BC, and AC) and constructing segments to join these midpoints.
An important property of the medial triangle is that it divides the original triangle into four smaller, congruent triangles that are each similar to the original triangle.
With this in mind we now that the four triangles are congruent. Then:
[tex]CF=DE[/tex]but we know that CF is half of BC, then:
[tex]DE=\frac{78}{2}=39[/tex]From the figure we also notice that:
[tex]\begin{gathered} BE=DF \\ BE=34 \end{gathered}[/tex]Ans that AB is twice BE, then
[tex]AB=68[/tex]Summing up we have:

Answers
Answer: James ate more pizza by 5/12 parts.
Step-by-step explanation:
To solve let us takes the lcm of the denominators 3 and 4
which is 12.
James ate 2/3 * 4/4 = 8/12 parts
Lucas ate 1/4*3/3= 3/12 parts
now, we can see 8/12>3/12
Therefore, James ate more pizza by 8/12-3/12= 5/12 parts.
The line parallel to y=1/4x+1 that passes through the point (6,-2)
Answers
Answer:
y = [tex]\frac{1}{4}[/tex] x - [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{4}[/tex] x + 1 ← is in slope- intercept form
with slope m = [tex]\frac{1}{4}[/tex]
• Parallel lines have equal slopes , then
y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
to find c substitute (6, - 2 ) into the partial equation
- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - 2 - [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]
y = [tex]\frac{1}{4}[/tex] x - [tex]\frac{7}{2}[/tex] ← equation of parallel line

The ground temperature at an airport is 11 °C. The temperature decreases by 7 °C for every increase of 1 kilometer above the ground. What is the temperature outside a plane flying at an altitude of 5 kilometers?
The temperature outside a plane flying at an altitude of 5 kilometers is
°C.
Answers
Under the linear assumption of temperature and altitude, the temperature outside the plane is - 24 °C.
What is the temperature outside a plane flying at a given altitude?
In this problem we must determine the temperature outside the plane on the assumption that the temperature decreases linearly with the altitude:
T(z) = T' + (ΔT / Δz) · z
Where:
T' - Temperate at ground level, in degrees Celsius.Δz - Level change, in kilometers.ΔT - Temperature change, in degrees Celsius.If we know that T' = 11, Δz = 1 and ΔT = - 7, then the temperature at an altitude of 5 kilometers is:
T(5) = 11 + (- 7 / 1) · 5
T(5) = 11 - 35
T(5) = - 24
The temperature outside the plane is - 24 °C.

6. There are 45 cans of mixed nuts. Each
can has 338 nuts. Below is Mary's work

Answers
The total number of nuts is 15210 and the missing number is 5
Number of cans of mixed nuts = 45 cans
Number of nuts in each can = 338 nuts
The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors.
Finding the total number of nuts we get:
Total number of nuts = Number of cans*Number of nuts in each can

3) -7y + 9 = 3y + 49
Answers
Answer:
y = -4
Step-by-step explanation:
first add 7y to both sides
9 = 10y + 49
second subtract 49 from both sides
-40 = 10y
flip it
10y = -40
now divide both sides by 10
y = -4
that is your answer
Answer: 7y+9=3y+49
We move all terms to the left:
-7y+9-(3y+49)=0
We get rid of parentheses
-7y-3y-49+9=0
We add all the numbers together, and all the variables
-10y-40=0
We move all terms containing y to the left, all other terms to the right
-10y=40
y=40/-10

Kyle invests $600 which earns 3% annual simple interest for 5 years Use A(t)=P (1+rt) to determine how much money he will have after 5 years. Interpret the rate of change in this situation
Answers
The amount of money that Kyle will have after 5 years is $690.
How to calculate the interest?From the information, Kyle invests $600 which earns 3% annual simple interest for 5 years.
The formula for the amount is given as:
A(t)=P (1+rt)
where P = principal = $600
R = rate = 3%
T = time = 5 years
This will be:
A(t)=P (1+rt)
A = 600 [ 1 + (3% × 5)]
A = 600 (1 + 0.15)
A = 600(1.15)
A = 690
