We want to find the moon's gravitational acceleration.
With the given information, we will see that the gravitational acceleration on the moon is: g = 1.625 m/s^2
We know that in a place with a gravitation acceleration g, if you drop something from a height H, the position equation of that object will be given by:
p(t) = (-g/2)*t^2 + H
In this case, we know that a feather falls 81.25cm in one second.
First, we can define H = 0 (because we can put the zero of the position where we want to)
Then if after one second the feather falls 81.25cm = 0.8125 meters, we need to solve:
p(1s) = -0.8125 m = (-g/2)*(1s)^2
Where the negative sign comes because the feather "falls" and we define the negative position as below.
Also notice that we did a change of units from centimeters to meters, by knowing that:
100cm = 1m
then:
81.25cm = 0.8125m
Now we just need to solve:
-0.8125 m = (-g/2)*(1s)^2
0.8125 m = (g/2)*(1s)^2
2*0.8125 m = (g)*1s^2
1.625 m = g*1s^2
(1.625 m)/(1 s^2) = g
We then can conclude that the moon's gravitational acceleration is:
g = 1.625 m/s^2

After enlarging his "U" in problem 3-26, Al has an idea. He drew a 60° angle, as shown in Diagram #1 at
right. Then, he extended the sides of the angle so that they are twice as long, as shown in Diagram #2.
"Therefore, the new angle must have measure 120°," he explained. Do you agree? Discuss this with your

When extending both sides of an angle, you are not changing the angle, so dat man wrong....

You bought a package of paper for $3 and some pencils for $2 each at the school store. You paid $15 for everything that you bought. How many pencils did you buy?
Answer:
6 pencils
Step-by-step explanation:
Total cost = paper * cost of a package + pencils * cost of a pencils
We bought 1 pack of paper at 3 dollars and p pencils at 2 dollars
15 = 1*3 + p*2
15 = 3+2p
Subtract 3 from each side
15-3 = 3+2p-3
12 = 2p
Divide by 2
12/2 = 2p/2
6 = p
How many pairs of opposite sides are parallel?
no pairs

2 pairs
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
In the given figure, no pair of opposite sides are parallel.
There are no parallel side in the given figure.
Given is a figure we need to determine if there are any parallel side or not,
So, the parallel sides are defined as =
When two or more sides of a polygon are described as parallel, it means that they never cross over and are always equally spaced apart.
In other words, these sides would never intersect or cross each other if you extended them endlessly.
Shapes like squares, parallelograms, rectangles, and trapezoids are frequently linked to the idea of parallel sides.
The opposing sides of these polygons are parallel to one another. For instance, just one pair of opposite sides in a trapezoid is parallel but both sets of opposite sides are parallel in a rectangle.
So according to the definition of parallel lines there are no parallel sides in the figure.

Your friend calculates the distance between points Q(1,5) and R(3,8), as shown below. What is his error?
The distance between two points is the number of units between them.
The distance between Q and R is 3.61 units
It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.
The distance (d) between two points is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
So, the distance QR is:
[tex]QR = \sqrt{(1 - 3)^2 + (5 - 8)^2}[/tex]
[tex]QR = \sqrt{(- 2)^2 + (- 3)^2}[/tex]
Evaluate exponents
[tex]QR = \sqrt{4 +9}[/tex]
[tex]QR = \sqrt{13}[/tex]
Take square root of 13
[tex]QR = 3.61[/tex]
Hence, the distance between Q and R is 3.61 units

All slope can be visualized as "rise over run" meaning the top number is how far you go up or down depending on whether it is positive or negative and run can be visualized as how far to the right you move or if it is negativ, how far to the left.

In the previous activity, you found an equation with a negative unit rate, y = -50x – 100. This equation gave the depth of a submarine, y, given time, x. It assumes that the submarine starts at a depth of 100 feet, and then starts descending at a rate of 50 feet per minute. In this activity, you will graph the equation.
Part A
Graph the equation y = -50x – 100 by going to your math tools and opening the Graph tool. Set the scale of the y-axis to range from -150 to 50, and set the x-values to range from -5 to 10. Paste a screenshot of your graph in the answer field.

Trey is taking his friends out to dinner to celebrate graduation. It will cost him $72 to reserve a table, and another $5 per guest. How many people can he invite if he can only spend up to $130?
Answer:
11 people
Step-by-step explanation:
first, youd subtract the table reservation price from the max price.
130 - 72 = 58
then, since each person costs $5, you find the highest multiple of 5.
in this case, its 55, which has 11 groups of 5 in it.
to make sure:
you can then subtract 55 from 58 to make sure there isnt any extra 5's.
58 - 55 = 3.

Masha bought red, green, and yellow balloons for a party. She bought 40 red balloons. The number of green balloons Masha bought is 3/5 of the number of red balloons. The number of green balloons is also 2/3 of the number of yellow balloons. while being inflated, 1/20 of the red balloons, 1/12 of the green balloons, and 1/36 of the yellows balloons popped. The remaining balloons were used as decoration. What part of all the balloons Masha purchased to decorate the party?
Answer:
95 balloons
Step-by-step explanation:
red = 40
green- 40x(3/5) = 24
yellow- 24÷(2/3) =36
36× (1/36) = 1. 1 yellow balloon popped
24× (1×12) = 2. 2 green balloons popped
40×(1/20) =2. 2 red balloons popped
40+24+36= 100
2+2+1=5
100-5 = 95 balloons left for decorations

The formula for converting from Celsius to Fahrenheit is F=9/5C+32. The Fahrenheit temperature of a certain city has never exceeded 86 degrees. How would you describe this using Celsius temperature?
Answer:
The temperature in Celsius in this city has never exceeded 30 °C
Step-by-step explanation:
Just substitute F by the temperature in Fahrenheit and solve the equation:
86 = 9C/5+32 Multiply both sides by 5
5×86 = 9C +32×5
430 = 9C + 160 Subtract 160 in both sides
270 = 9C Divide both sides by 9
30 = C

Make a system of equations.
Let s be the number of skips interviews and w be the number of woodys interviews.
s=w-8
s+w=20
Then just use algebra to rearrange and find each persons interviews.
For this one we can rearrange the second equation to get s=20-w.
Since we have two solutions for s we can set them equal.
w-8=20-w
2w-8=20
2w=28
w=14
Now that we have the number of woodys interviews substitute it into the first equation to get skips interviews.
s=w-8
s=14-8
s=6
So skip had 6 interviews and woody had 14 interviews.
