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.
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:
[tex]\begin{gathered} DE=39 \\ AB=68 \\ BE=34 \end{gathered}[/tex]the probability that a fair die falls on 6 is 1/6. however, if that fair die is one of two dice, and you know that the sum of the two dice is 12, then the probability that the fair die fell on 6 is ?
Answer:36
Step-by-step explanation:
1/6 is 6
so we need to find 6/6 which would be 6×6=36
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
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
The amount is $690.

Quinn knit a total of 4 centimeters of scarf over 2 nights. how many nights will quinn have to spend knitting in order to knit a total of 70 centimeters of scarf?
The nights required by Quinn in order to knit a total of 70 centimeters of the scarf is equal to 35.
The number of nights required by Quinn in order to knit a total of 70cm of the scarf can be calculated using multiplication. Multiplication can be described as one of the four basic arithmetic operations in which we perform the repeated addition of the same number or value. This problem can be solved using cross-multiplication as follows;
2 nights = 4 cm of scarf
x nights = 70 cm of scarf
70 × 2 = 4(x)
140 = 4(x)
x = 140 / 4
x = 35
Therefore, Quinn will have to spend 35 nights knitting in order to knit a total of 70 centimeters of the scarf.

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.
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.

James and Lucas are eating a pizza. James ate 2/3 of the pizza and Lucas ate 1⁄4 of pizza. Who ate more pizza and by how much?
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.
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?
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.

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

3) -7y + 9 = 3y + 49
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
