To make sure that a given parallelogram is a rectangle, at least hon many of
its angles must measure 90°?
A. Four
B. Two
C. Three
D. One
Answers
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°.

After the game is over, the turnstile count shows 1787 people attended the game. The total receipts were $5792. Find the number of each general admission tickets sold.
Answers
Given :
Reserved seat tickets for the football game cost $4.00 each and general admission tickets cost $3.00 each.
After the game is over, the turnstile count shows 1787 people attended the game. The total receipts were $5792.
To Find :
The number of each general admission tickets sold.
Solution :
Let, general admission are x.
So, Reserved seat tickets will be 1787 - x.
Now, total amount T = 3x + 4( 1787 - x )
T = $5792
3x + 4( 1787 - x ) = $5792
-x + 7148 = 5792
x = 1356
Therefore, the number of each general admission tickets sold are 1356.
Hence, this is the required solution.

70 = 100 - 2•15 is 2 s.d.'s below the mean.
130 = 100 + 2•15 is 2 s.d.'s above the mean.

A flower garden is shaped like a circle. Its diameter is 30 yd. A ring-shaped path goes around the garden. Its outer edge is a circle with diameter 36 yd.The gardener is going to cover the path with sand. If one bag of sand can cover 6 yd², how many bags of sand does the gardener need? Note that sand comes only by the bag, so the number of bags must be a whole number. (Use the value 3.14 for π.)
Answers
We started by finding the area of the two respective circles, then we found the area of the path, after which we estimated the number of sand bags needed to be 51.8 bags
Ans 51.8 bags
Area of CircleGiven data
Diameter of flower garden d = 30 ydDiameter of outer edge D = 36 ydNo of bags of sand = ??Area of path = Area of outer edge - area of garden
Area of path = πD^2/4 - πd^2/4
Area of path = 3.142*36^2/4 - 3.142*30^2/4
Area of path = 3.142*1296/4 - 3.142*900/4
Area of path = 4072.032/4 - 2827.8/4
Area of path = 1018.008 - 706.95
Area of path = 311.058 square yd
1 bag of sand will cover 6yd^2
x bags of sand will cover 311.058 yd^2
cross multiply we have
x = 311.058/6
x = 51.843 bags of sand

-x=-y-6
x+2y=12
a. (7,1)
b. (8,2)
c. (6,0)
d. (9,3)
Answers
Answer:
c. (6, 0)
Step-by-step explanation:
First, add y on both sides of the first equation, so it's easier to solve:
-x+y = 6
x+2y = 12
Then, add the 2 equations:
3y = 18
y = 6
Since c is the only one with a 6, we can deduce that the answer is c.
We can further check by plugging y back into the first equation:
-x+6 = 6
-x = 0
x = 0
This confirms that the answer is c.

your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answers
Answer:
x = 4
Step-by-step explanation:
Given the points (4, - 1) and (4, 8)
Note the x- coordinates are 4 in both cases.
This indicates the line passing through the points is vertical with equation
x = c
where c is the value of the x- coordinates the line passes through. In this case 4, thus
x = 4 ← equation of vertical line

∠ CAB = 90°,
∠ ABC = 51° and AB = 8.6.
Calculate the length of BC rounded to 3 SF.
Answers
Answer:
BC ≈ 13.7
Step-by-step explanation:
using the cosine ratio in the right triangle
cos51° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{8.6}{BC}[/tex] ( multiply both sides by BC )
BC × cos51° = 8.6 ( divide both sides by cos51° )
BC = [tex]\frac{8.6}{cos51}[/tex] ≈ 13.7 ( to 3 sf )

The price of Stock A at 9 A.M. Was $14.17. Since then, the price has been increasing at the rate of $0.11 each hour. At noon the price of Stock B was $14.67. It begins to decrease at the rate of $0.16 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answers
Answer:
0.63 hours
Step-by-step explanation:
We are told that at 9am, the price of Stock A was $14.17 and we are told it increases by $0.11 each hour.
Thus, for x hours, the price will be;
P_a = 14.17 + 0.11x
Now,by noon, it would have been 3 hours.
Thus;
P_a = 14.17 + 0.11(3)
P_a = 14.17 + 0.33
P_a = $14.50
Now, at that same noon, another product known as stock B had a price of $14.67. We are told it begins to decrease at the rate of $0.16 each hour.
Now, we want to find how many how many hours will the prices of the two stocks be the same. If the number of hours is x, this means that;.
14.5 + 0.11x = 14.67 - 0.16x
Rearranging,we have;
0.11x + 0.16x = 14.67 - 14.5
0.27x = 0.17
x = 0.17/0.27
x = 0.63 hours
