All four arms of a mechanical jack are the same length, and they form a parallelogram. Turning the crank pulls the arms together, raising the top of the jack. How high is the top of the jack when the crank is 5 inches off the ground? Explain.
Answer:
10 inches
Step-by-step explanation:
The top of the jack is 10 inches from ground.
What is parallelogram?A parallelogram is a two-pair quadrilateral with parallel sides. A parallelogram has opposite sides that are the same length and have opposite angles that are the same size. Additionally, the interior angles on the same transversal side are supplemental. 360 degrees are the sum of all the interior angles.
A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.
Given Jack is in shape of parallelogram,
height of crank of jack from ground = 5 inches
to find the distance from ground to top of jack
since crank is at centre of jack and bottom to top of jack makes the diagonal of parallelogram,
distance from crank to top of jack is 5 inches,
because The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal.
total length from ground is 5 + 5 = 10 inches
Hence length from ground to top of jack is 10 inches because diagonals bisect each other.

f (x) = x + 5 and g(x) = 2x Find (f +g)(x)
Answer:
Step-by-step explanation:
f(x)=x+5 and g(x)=2x

Hi there! The answer for this question would be 9!
Explanation:
0.09 is also 9 since 1.00 is 1 whole in fraction form. This means that 0.09 is also 9/100 in fraction form.
Final Result: 9
Answer: 9
Step-by-step explanation:
On both sides of the equation, there is the 27/100. So we can essentially ignore that because the other two terms just have to be equal. The 0.09 has a 9 in the hundredths place. So that means the decimal is equivalent to 9/100

Kevin measured a line to be 12.4 inches long. If the actual length of the line is 15.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answer:
The percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]
Step-by-step explanation:
Estimated length of a line = 12.4 inches
Actual length of the line = 15.7 inches
Error = 15.7 - 12.4 = 3.3 inches
Percent error of the measurement [tex]=\frac{3.3}{15.7}(100)=21.02[/tex] ≈ 21.0
So, the percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]
Your math teacher loves to collect markers and pencils. If she has 9 more markers than pencils and has a total of 41 writing utensils, how many pencils does your teacher have? please explain pleaseee
Answer:
16
Step-by-step explanation:
There is a total of 41 writing utensils, if you have 9 more pencils than markers you need to subtract 9 from 41. Then half that number so you will get the total amount of pencils.
41-9=32

Glen, Andre, and Ramón share the cost of renting a vacation cottage. The total cost is $960. Glen pays 30% of the total cost. Andre pays 0.45 of the total cost. Ramón pays the rest. How much does Ramón pay?
Answer:
Ramon pays $240.
Step-by-step explanation:
30% of $960 is $288, so Glen pays $288
0.45 = 45%
45% of $960 is $432, so Andre pays $432
30% + 45% = 75% meaning Ramon pays 100% - 75% which is 25%.
25% of $960 is $240. So, Ramon pays $240.
You could also add up the payments of Andre and Glen and subtract that sum from $960 to get the same answer.

Assume that y varies directly with x. If y=2/5 when x=1/3, find y when x=1/4. Enter in any fractions using a / (e.g. "1/2" is the same as 12).
x=3/15 thus y=6/15 If x=1/4 then y =2/4
y = -x + 6
what’s the solution?
Answer:
Assuming you are solving for x:
x = 6 - y
Step-by-step explanation:
y = -x + 6
y + x = 6
x = 6 - y

Mason misses 25% of the free throws he attempts in a season. How many total free throws did he attempt if he missed 52?
Given:
Mason misses 25% of the free throws he attempts in a season.
Number of missed free throws = 52
To find:
The total number of free throws.
Solution:
Let x be the total number of free throws.
Mason misses 25% of the free throws he attempts in a season.
Number of missed throws = 25% of x
Number of missed free throws = 52
Now,
[tex]\dfrac{25}{100}x=52[/tex]
[tex]\dfrac{1}{4}x=52[/tex]
Multiply both sides by 4.
[tex]x=52\times 4[/tex]
[tex]x=208[/tex]
Therefore, the total number of free throws is 208.

By simplifying JUST the right side and re-arranging them
2 + 4x = 5 - 3(x + 1),
2 + 4x = 5 - 3x -3,
2 + 4x = 5 -3 - 3x
Explain why a balance of less than - $10
represents a debt greater than $10.
Answer:
Answer down below.
Step-by-step explanation:
You can see that the 10 is negative. Now, imagine a number line. If you were to plot that on the number line, its less than 0. Anything in the positives is in the positive number range. If you were to do the same for negatives, it would represent a negative value, or in money standards, would be in debt.

Which of the following are point slope form of the line going through (-4,6) and (1,2)
Answer:
answer in comment
Step-by-step explanation:
So, we have to find the slope of the line. We are given two points, so we can use those:
(x1,y1) = (-4,6)
(x2,y2) = (1,2)
m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5
Also, we know that point-slope is of the form:
(y-y1) = m*(x-x1)
It doesn't matter which point you use, though, you can also use:
(y-y2) = m*(x-x2)
So we can plug the variables into the equation and get:
(y-2) = -4/5*(x-1)
OR
(y-6) = -4/5*(x+4)
You picked two marbles from a bag and record their color. How can you make your selections independent events? Dependent events?
Answer:
Let's suppose the next case:
We have a bag, where there are 5 red marbles, and 5 blue marbles.
We have a total of 10 marbles.
Suppose that we pick a marble and we do not replace it, and suppose that the first one is a red marble.
Then now we have in the bag a total of 4 red marbles and 5 blue marbles.
Now let's find the probability of picking a blue marble, this will be equal to the quotient between the number of blue marbles (5) and the total number of marbles (9)
P = 5/9
Now, suppose that instead of a red marble in the first pick, we had a blue marble.
Then now we have 4 blue marbles and 5 red marbles in the bag.
Again, the probability of picking a blue marble will be equal to the quotient between the number of blue marbles (4) and total numbergof marbles (9)
P = 4/9
Then the first pick does affect the probabilities for the second pick, this means that if we do not replace the first marble we pick, then the events will be dependent.
Now, if we replaced the first marble we picked (we put it again in the bag) then the number of blue marbles and red marbles is always the same, then in this case bot events will be independent (the first event will not affect the second event)
