Answer:
D. One
Step-by-step explanation:
A parallelogram will have two sets of equal sides. Since we have that fact, all we need to know are the angles.
A quadrilateral will have a total of 360° in its angles. If only one angle is equal to 90°, then we can do the math to figure out that all the others must be 90° as well. A rectangle is a parallelogram with the opposite sides being parallel and all the angles being 90°. This then answers the question.
"The Math"
-> Keep in mind there will be four angles
-> Once we subtract the first angle of 90°, we will have three angles left. Hence why we divide by 3.
360° - 90° = 270°
270° / 3 = 90° ✓
To make sure that a parallelogram is a rectangle, at least one angle must be 90°. The correct answer is D.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
Let consider given parallelogram be ABCD.
All of the angles of a parallelogram must be 90° for it to be a rectangle.
Let ∠A = 90°.
Since opposite angles of a parallelogram are equal
So, ∠C = ∠A = 90°
And adjacent angles are supplementary and their sum is 180°.
So, ∠A + ∠B = 180°.
∠B = 180°- ∠A = 180° - 90° = 90°
As we know that opposite angles of a parallelogram are equal
So, ∠D = ∠B = 90°.
If all four angles are right angles (90°), then given one angle = 90°.
To make sure that a parallelogram is a rectangle, at least one angle must be 90°.

Solve −x+4y−28=0 for y .
Answer:
y= -x/4 +7
Step-by-step explanation:
x+4y−28=0
Subtract x from both sides. Anything subtracted from zero gives its negation.
4y−28=−x
Add 28 to both sides.
4y=−x+28
The equation is in standard form.
4y=28−x
Divide both sides by 4.
4y/4 = 28−x/4
Dividing by 4 undoes the multiplication by 4.
y= 28-x/4
Divide −x+28 by 4.
y= -x/4 +7

An aircraft carrier traveled to dry dock an back. The trip there took 2 hours and the trip back took 3 hours. It averaged 5 miles per hour faster on the trip there than on the return trip. Find the aircraft carrier's average speed on the outbound trip
Answer:
Step-by-step explanation:
Average speed = distance/time
Trip to dry dock
Let x be the velocity
Time = 2hours
Distance = average speed ×time
Distance = x×2
Distance = 2x
Return trip
Velocity = x-5 (5 miles per hour faster on the trip there than on the return trip)
Time = 3hrs
Distance = 3(x-5)
Since the distance is the same both to and fro;
2x = 3(x-5)
2x = 3x -15
2x-3x = -15
-x = 15
x = 15
Hence the aircraft carrier's average speed on the outbound trip is 15miles/hour

Two teachers compared the mean absolute deviation of the scores from the semester exam they gave to their students. Mrs. Alvarez's scores had a lower mean absolute deviation than Mr. Crawford's scores. What can we conclude? * 10 points A. Mrs. Alvarez's scores were lower than Mr. Crawford's scores. B. Mrs. Alvarez's scores were more spread out than Mr. Crawford's scores. C. Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores. D. Mrs. Alvarez's scores were higher than Mr. Crawford's scores.
Answer:
C. Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores.
Step-by-step explanation:
Mean Absolute Deviation is one of the Statistical measures which we can you to determine the variation that exist amongst a given set of data
Mean Absolute Deviation can be defined as how far or the distance between one set of data to another set of data.
The smaller the Mean Standard Deviation, the lower the degree of variation in the set of data. The data is less spread out
The larger the Mean Standard Deviation, the higher the degree of variation in the set of data. The data is Largely spread out
We are told in the question that:
Mrs. Alvarez's scores had a lower mean absolute deviation than Mr. Crawford's scores. Our conclusion would be that Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores.

Molly’s monthly payment by using the Bankrate calculator is $286 per month.
It is given that
The downpayment Molly has = $2500.
Interest rate APR = 1.9%
Cash allowance by dealer = $500
Selling price = $25,495
Loan tenure N= 7 years
Amount of loan needed = 25495-2500-500 = $22495
What is Equated monthly payment(EMI)?An equated monthly installment (EMI) is a set monthly payment provided by a borrower to a creditor on a set day, each month.
The EMI or monthly payment will be calculated by the following formula,
[tex]EMI = \frac{P.\frac{APR}{12} .(1+\frac{APR}{12})^N }{(1+\frac{APR}{12})^N-1 }[/tex]
Put APR =0.019(decimal value of APR)
N = 7
EMI = $286 per month.
Therefore, Molly’s monthly payment by using the Bankrate calculator is $286 per month.

Nicole gave her mother $40.00. Her mother also applied the money that she owed Nicole for babysitting. Nicoles mother then gave her back $5.26. How much did Nicoles mother owe Her for babysitting?
Answer:
$9.48Step-by-step explanation:
The total amount for the order is
$9.75+$29.99+ $15.00=$54.74
let the money her mother owes her be x
so summing all the amount plus the balance given to her must equal $54.74

Answer:
Given: An Angle in the figure is right angle. Its measure = 90°
So,
∠2 = 90° ( vertically opposite angles are equal )
∠1 + ∠2 = 180° ( Linear Pair )
∠1 = 180 - 90
∠1 = 90°
So, ∠1 and ∠2 are
Right angles because measure of both angles are 90°.
Adjacent angles because both a common arm and a common vertex.
Supplementary angles because sum of both angles is 180°.

An object is moving at a speed of 5 kilometers every 4.5 hours. Express this speed miles per minute. Round your answer to the nearest hundredth. Someone please help me I’m struggling with this one
Answer:
speed is 0.01 miles per minute
Step-by-step explanation:
We know speed = distance/time
since we need speed in miles per minute we need to convert KM into miles
and hours in minutes
--------------------------------------------------------
distance = 5 km
1 km = 0.621371 miles
5KM = 5*0.621371 miles = 3.10686 miles = 3.12 miles(rounded to nearest hundredth)
1 hour = 60 minutes
4.5 hours = 4.5*60 minutes = 270 minutes
speed = distance in KM/time in minutes = 3.12 miles/270 minutes
speed = 0.012 miles per minute
rounding the answer to the nearest hundredth
speed is 0.01 miles per minute

Cameron earns four times as much as a tutor than a fast food worker. His sister only has one job because she earns one and a half times as much as a tutor than Cameron. Her weekly wage is $250 more than Cameron. How much does Cameron earn as a tutor?
Answer:
$500 per week.
Step-by-step explanation:
Let Cameron earns $x as a tutor.
As his sister earns one and a half times as much as a tutor, so, his sister earns $1.5x.
Since the weekly wage of Cameron's sister is $250 more than Cameron, so
[tex]1.5x=x+250[/tex]
[tex]\Rightarrow 1.5x-x=250[/tex]
[tex]\Rightarrow 0.5x=250[/tex]
[tex]\Rightarrow x=500.[/tex]
Hence, the weekly earning of Cameron is $500.

What is the equation of the line that passes through the point (3,-5) and has a slope of 0
Answer:
The answer is
[tex] \huge y = 5[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (3,-5) and slope 0
We have
[tex]y + 5 = 0(x - 3) \\ y + 5 = 0 \\ y = 5[/tex]
We have the final answer as
[tex]y = 5[/tex]
