Step-by-step explanation:
the conversion from inches to cm is 2.54cm per inch
with that in mind,
take the 712 inch pencil and multiply it by 2.54 cm to convert it
leading to
712 * 2.54 = 1808.48 cm long.

What’s the midpoint of a line segment joining the points (5,-4) and(-13,12)?
Answers
Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
((x1 + x2)/2 , (y1 + y2)/2)
((5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)
7. Find the area of the figure.
Is it right??
Answers
Answer:
28.5 units²
Step-by-step explanation:
You are correct.
You divided the figure into a square, a rectangle and a triangle.
You can also just divide into a rectangle and a triangle as I did below, and there are other ways of dividing the figure to find the area.
Bottom rectangle: 8 units by 3 units
Top triangle: base = height = 3 units
total area = area of rectangle + area of triangle
total area = length × width + base × height / 2
total area = 8 units × 3 units + 3 units × 3 units / 2
total area = 24 units² + 4.5 units²
total area = 28.5 units²

FN = √OP² - ON²

Peter can mow his lawn in 6 minutes. Peter's son can mow it in 8 minutes. How long will it take them to do it together?
Answers
Answer:
3 minutes 26 seconds
Step-by-step explanation:
rate x time in Distance problems, and W = rate x time in work problems. The Work is generally 1, the whole job.
For Peter the formula is 1 (lawn mowed) = 1/6 lawn per minute x 6 minutes.
For the son the formula is 1 = 1/8 * 8.
Add their rates together, 1/8 + 1/6 = 3/24 + 4/24 = 7/24.
The equation for their rate working together is 1 = 7/24 * t
Divide both sides by 7/24 to find t. t = 1 / 7/24 = 1 * 24/7 = 24/7 = 3 and 3/7 minutes = approx. 3 minutes 26 seconds.

What is the distance between (4, −3) and (9, −3) ? Enter your answer in the box.
Answers
Answer:
5 units
Step-by-step explanation:
Luckily, we don't need to use the distance formula as we just need to find the distance between the x-coordinates. Thus, |4-9| = |-5| = 5, which means that the distance between (4,-3) and (9,-3) is 5 units
Answer:
5
Step-by-step explanation:
Point (4, -3) and point (9, -3) have the same y-coordinate of -3. Therefore, both points are on the line y = -3.
Any line that is y = {number} is a horizontal line.
Therefore, to find the distance between the points, find the difference between the x-values:
9 - 4 = 5
Therefore, the distance between (4, −3) and (9, −3) is 5

Answers
Answer:
Step-by-step explanation:
All triangles without exception, have 3 angles that add to 180o.
You know two of them. The statement above will help you get the third.
35 + 33 + x = 180 Combine the left
68 + x = 180 Subtract 68 from both sides.
x = 180 - 68
x = 112
Answer: The value of x is 112
Step-by-step explanation:
add the two values given: 35+33= 68
then subtract 68 from 180 (sum of angles is 180°) = 112
112+35+33= 180

Answers
Answer:
x= 8 y= -4
Step-by-step explanation:2x=16 divide 2 on both, x=8, plug in 8 for x, -1x8-3y=4 will become = -8-3y=4 add 8 on both sides and divide by -3 the answer will be -4
Answer:
Step-by-step explanation:-
-1x - 3y = 4 (eqn 1)
2x = 16 (eqn 2)
from eqn 2
2x = 16
x = 16/2
x = 8
Substitute x = 8 into eqn 1
-1(8) - 3y = 4
-8 - 3y = 4
-3y = 4 + 8
-3y = 12
y = 12/-3
y = -4
therefore, x = 8 and y = -4
Song randomly pulled a marble from a bag, recorded its color, put it back, and repeated. The results are shown in the following table.
Color Frequency
Blue 22
Green 19
Purple 20
Red 18
Yellow 21
If Song were to repeat the experiment 25 more times, how many of those times should he expect to pull a purple marble?
Enter your answer as a number, like this: 42
Answers
Step-by-step explanation:
when counting the events we see, he did
22+19+20+18+21 = 100 experiments.
and he got in 20 cases out of the possible 100 a purple marble.
that means the observed probability to pull a purple marble is 20/100 = 1/5.
now he does 25 more pulls.
each with the probity of 1/5 to pull a purple marble.
so, he should expect to pull a purple marble 25×1/5 = 5 times.
