Explanation:
The x coordinates are the same, so we subtract the y coordinates and use absolute value to ensure the result isn't negative.
|-30.5 - 9.7| = |-40.2| = 40.2
One unit represents 1 km, so 40.2 units represent 40.2 km
This converts to 40,200 meters. Multiply by 1000 to go from km to meters.

Julie has a jewelry box shaped like a cube. If the volume is
216 cm³, what is the edge length of Julie's jewelry box?
A 14.7 cm
B 108 cm
C 6 cm
D 72 cm
Answer: C) 6cm
Step-by-step explanation:
6³= 6x6x6
6x6x6= 216
Answer:
Choice C: 6 cm
Step-by-step explanation:
The sides of a cube are all of equal length
If each side is a cm, then the volume = a x a x a = a³ cubic cm
So a = ∛V where V is the volume
Since we are given V = 216 cm³,
each side = ∛21 = 6 cm

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.

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.

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.

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:

The line parallel to y=1/4x+1 that passes through the point (6,-2)
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

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
y=-4
