Determine the height of the quadrilateral. -
Determine the length of the quadrilateral. -
What shape do the points form?
What is the area of the quadrilateral?
What is the perimeter of the quadrilateral?
Answer:
height: 6 unitslength: 7 unitsshape: rectanglearea 42 square unitsperimeter: 26 unitsStep-by-step explanation:
Height
The height of it is the distance between the bottom and the top. You can count grid squares (6), or you can subtract y-coordinates:
4 -(-2) = 4 +2 = 6
The height of the figure is 6 units.
__
Length
The length is the difference between the left side and the right side. Once again, you can count grid squares (7), or you can subtract x-coordinates:
4 -(-3) = 4 +3 = 7
The length of the figure is 7 units.
__
Shape
The two upper points are on the same horizontal line, as are the two lower points. The two left-side points are on the same vertical line, as are the two right-side points. Vertical and horizontal lines are at right angles, so all of the corner angles are 90°. The quadrilateral is a rectangle.
__
Area
The area of the quadrilateral is the product of its length and height:
A = LH
A = (7 units)(6 units) = 42 units²
The area is 42 square units.
__
Perimeter
The perimeter is the sum of the lengths of the four sides. There are to sides that are 6 units long, and 2 sides that are 7 units long.
P = 2(6 +7) = 26
The perimeter is 26 units.

Brianna has $2.80 in quarters, dimes and nickels in her purse. She has nine more dimes than quarters and six more nickels than quarters. How many of each coin does she have?
Answer:
She has 4 quarters, 13 dimes, and 10 nickels in her purse
Step-by-step explanation:
Let q be the amount of quarters, d be the amount of dimes, and n be the amount of nickels she has in her purse. We can use this to set up a system of equations:
25q+10d+5n=280
This is because a quarter is 25 cents, a dime is 10 cents, and a nickel is 5 cents. We also have to convert $2.80 to cents since all our other values are in cents.
d=q+9
She has 9 more dimes than quarters
n=q+6
She has 6 more nickels than quarters
We can solve this system using substitution (substitute q+9 for d and q+6 for n)
25q+10(q+9)+5(q+6)=280
25q+10(q)+10(9)+5(q)+5(6)=280
25q+10q+90+5q+30=280
40q+120=280
Subtract 120 from both sides
40q=160
Divide both sides by 40
q=4
Now we plug this back into the other equations to find the amount of nickels and dimes
d=q+9=4+9=13
n=q+6=4+6=10
She has 4 quarters, 13 dimes, and 10 nickels in her purse

Please HELP IN 10 MINS!!!!!!!!!!!!!!!!!!!!Lisa, Melinda, and Rahul love the same board game. The game must
be played by at least two people. Lisa can play every two days,
Melinda can play every three days, and Rahul can play every four
days. Today, all three played 1 game together. What is the total
number of games they will play from Day 1 to Day 50 if today is
Day 1? (Exactly 1 game is played per day.)
Answer:
25 games were played
Step-by-step explanation:
I first found how many games were played in 10 days
and then multiplied it by 5 to know how many games were played in 50 days
(but I am not sure if it is correct since it said that 1 game was played everyday and with rules I am not sure if it is even possible)
feel free to correct me
Answer: 17
Step-by-step explanation:
Lisa and Melinda will play together 8 times
Lisa and Rahul will play together 12 times
Melinda and Rahul will play together 4 times
So total games are 24 -- but they all will play together 4 times.
Since, "exactly 1 game is played per day", they cannot play 2 and 3 together at any day.
So total number will be: (8-4) + (12-4) + (4-4) = 12
Now, we must consider 4 where they played all 3 together; so total number: 12 + 4 = 16
Also, they already played 1 game at 1st day; so total number: 16 + 1 = 17

The graph of a function f is shown above. What is the value of [tex]\int\limits^7_0 {f(x)} \, dx[/tex]
==============================================
Explanation:
Split the graph into separate regions (see the diagram below)
The red trapezoid has the parallel vertical sides of b1 = 1 and b2 = 2. The height of the trapezoid is h = 2
The area of the red trapezoid is
A = h*(b1+b2)/2 = 2*(1+2)/2 = 3
--------------
The blue rectangle has a horizontal side of 2 and vertical side of 2. Its area is 2*2 = 4 square units.
--------------
The pink triangle has a base of 1 and height of 2
area = base*height/2 = 1*2/2 = 1 square unit
--------------
The green triangle has an area of base*height/2 = 2*2/2 = 2 square units
--------------
For any region above the x axis, it gets assigned a positive area. Anything below the x axis gets a negative area to counterbalance the positive areas.
The regions above the x axis add to 3+4+1 = 8 square units. Then we subtract off the area of the green triangle to get 8-2 = 6 square units.
Therefore, [tex]\displaystyle \int_{0}^{7}f(x)dx = 6[/tex]

The sum of several consecutive natural numbers is 2012. How many numbers were in that sum
Answer:
8
Step-by-step explanation:
first number = a, there are n numbers
so last number is a + n - 1
sum = [a + (a + n - 1)} * n/2 = (2a + n - 1) / 2 = 2012
n * (2a + n - 1) = 2012 * 2 = 4024
4024 is even, so n must be even, divisible by 2, 4, 8
4024 = 2 * 2012 = 4 * 1006 = 8 * 503
If n = 2, 2a + n - 1 = 2012, 2a + 2 - 1 = 2012, 2a = 2011, impossible.
If n = 4, 2a + n - 1 = 1006, 2a + 4 - 1 = 2a + 3 = 1006, 2a = 1003, impossible
If n = 8, 2a + n - 1 = 503, 2a + 8 - 1 = 2a + 7 = 503, a = 248
so n = 8, a = 248
Betty is having invitations printed for a holiday party. It costs $3.90 to set up the printing machine and $2.44 per invitation. In the equation below, x represents the number of invitations Betty is having printed, and y represents the cost to print the invitations.
y = $2.44x + $3.90
How much will it cost Betty to print 100 invitations?
A.
$392.44
B.
$251.80
C.
$103.90
D.
$247.90
Answer:
D) $247.90
Step-by-step explanation:
Understanding the equation:[tex] \underline{\sf{y = 2.44x + 3.90}}[/tex]
y is the dependent function whereas x is the independent function.
(What does this mean?)
The values of y depend on the values of x, I.e., any change in the value of x causes a change in the value of y, meanwhile, the opposite doesn't happen.
x represents the number of invitations y represents the cost to print the invitationsThe cost to print the invitation depends on the number of invitations, for real.
Solution to the problem:The question asks us to find the cost of printing 100 invitations.
Substituting x for 100:
y = (2.44 × 100) + 3.90
y = 244 + 3.90
y = 247.90
Answer:The value of y obtained for x = 100 is the cost of printing 100 invitations – $ 247.90

In how many ways can a committee of three men and three women be formed from a group of eight men and seven women
==========================================================
Explanation:
Order doesn't matter when it comes to committees without rankings. Each person on the committee is of equal rank to anyone else. This means we'll use a combination instead of a permutation.
We have 8 men and 3 seats to fill for the men. Plug n = 8 and r = 3 into the nCr combination formula
n C r = (n!)/(r!(n-r)!)
8 C 3 = (8!)/(3!*(8-3)!)
8 C 3 = (8!)/(3!*5!)
8 C 3 = (8*7*6*5*4*3*2*1)/((3*2*1)*(5*4*3*2*1))
8 C 3 = (40320)/((6)*(120))
8 C 3 = (40320)/(720)
8 C 3 = 56
This means there are 56 ways to select the three men from a pool of eight.
Through similar steps, you should plug n = 7 and r = 3 into the nCr combination formula to get 7 C 3 = 35. This means there are 35 ways to pick the three women from a pool of seven.
Overall, there are 56*35 = 1960 ways to select the entire committee of 3 men and 3 women (from a pool of 8 men and 7 women).
Suppose the mean GMAT score is 550 with a standard deviation of 100. Hayden takes the GMAT and is told his z-score is 2.5. Interpret the meaning of a z-score in this context. And what's Hayden's Score?
z-scores are used to describe normal distributions
The interpretation of a 2.5 z score is that, Hayden's score is 2.5 standard deviations below the 550
How to interpret the z-scoresThe z-score is given as:
z = 2.5
The mean and the standard deviation are:
Mean = 550
Standard deviation = 100
A z-score is the number of standard deviations above or below the mean.
Hence, a 2.5 z score is that, Hayden's score is 2.5 standard deviations below the 550
