Areas of parallelograms and Triangles (PLEASE HELP)
Answer:
I hope this helps :)
Step-by-step explanation:
The formula for the area of a triangle is: height(h) x base(b) / 2
Triangle number 1 - 3 x 8 / 2 = 24 / 2 = 12Triangle number 2 - 8 x 6 /2 = 48 / 2 = 24Triangle number 3 - 4 x 3 / 2 = 12 / 2 = 6The formula for the area of a parallelogram is: base(b) x height(h)
Parallelogram number 1 - 7 x 4 = 28Parallelogram number 2 - 5 x 8 = 40Parallelogram number 3 - 6 x 3 = 18Leigh and Sara paid $1,178 last month to rent their apartment. Last month had 31 days.

Answer:
first quotient is 31 second quotient is 6
Step-by-step explanation:
divide 1,178 with 31 so that's how you get your answer:)
Lary scored 180 points this season in 15 games. write a equation that repersents how many ponits larry scored per game this season
Hey can someone help I am stumped.
Add the two equations together to get:
4y = -4
Solve for y by dividing both sides by 4:
Y = -1
Now you have a value for y, solve for x in the first equation:
2x + 3(-1) = 7
2x -3 = 7
Add 3 to both sides:
2x = 10
Divide both sides by 2:
X = 5
Answer: x = 5 and y = -1

A keyboarding instructor at a community college collected data comparing a student's age and their typing speed. The equation for the line of best fit is given at y = -1.4x + 117.8, where x is the "age in years" and y is the "typing speed."
If you are 25 years of age. what is your typing speed?
A-153 words per minute
B-83 words per minute
C-63 words per minute
D-102 words per minute
HELP THIS IS TIMED!!!!
in answer:
The answer would be B
Step-by-step explanation:
Going off the y=mx+b equation, you would multiply -1.4 by 25 then add 117.8 to that result. The total of your equation would result in 82.8 words per minute.

{30 POINTS!} HELP! Two communications companies offer calling plans. With Company X, it costs 35¢ to connect and then 5¢ for each minute. With Company Y, it costs 20¢ to connect and then 4¢ for each minute. Write and simplify an expression that represents how much more Company X charges, in cents, for n minutes
(35+5n)−(20+4n)
Answer:
(20 + n)¢
Step-by-step explanation:
With Company X, it costs 35¢ to connect and then 5¢ for each minute.
So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢
Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.
So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.
Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)
Westin performed an experiment in which he randomly pulled a marble from a bag, recorded its color, put it back, and then repeated. He did this 36 times, and 9 of those times he pulled a purple marble.
Which bags of marbles are good models for this experiment?
Select two that apply.
A ) 4 purple, 5 blue, 2 green, 1 red
B ) 4 purple, 5 blue, 2 green, 1 red
C ) 9 purple, 9 red, 9 green
D ) 9 purple, 9 red, 9 green
E ) 1 purple, 1 blue, 1 green, 1 red
F ) 1 purple, 1 blue, 1 green, 1 red
G ) 4 purple, 4 blue, 4 yellow, 4 orange
Answer:
Step-by-step explanation:
Based on the experiment, 9 times he pulled a purple marble out of the 36 trials.
That means he has a 1/4 probability of pulling a purple marble
This means that the purple marble ideally makes up one-quarter of the total marble in the bag.
Choice G and F satisfy the condition as stated above.
Hope that helps!

The variables x and y have a proportional relationship, and y= 5/6 which equation represents this relationship? x= 3/4. Which equation represents this relationship?
Answer:
(d) y= (1 1/9)x
Step-by-step explanation:
A proportional relation is described by the equation ...
y = kx
Dividing by x shows how to find the value of k:
k = y/x
For the given values of y and x, the value of k is found to be ...
k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9
The relationship is represented by the equation ...
y = (1 1/9)

Jasmine picked 2/5 of a bucket of strawberries. Her friend picked 3/4 of the amount Jasmine picked. How much
of a bucket of strawberries did Jasmine's friend pick?
Answer:
If Jasmine picked 4/10 (which is equivalent to 2/5) then that would mean Jasmine's friend picked 3/10.
If Jasmine picked 4 berries out of 10, that means Jasmines friend picked 3 berries out of ten.
Step-by-step explanation:
2/5 x 4 = 8/20
8/20 x 5 = 40/100
three quarters of 40/100 is 30/100
