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.

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°.

Answer:

Step-by-step explanation:

1 Meter is equal to 100 centimeters

Answer: True

Explanation: 1 meter=100 cm

Step-by-step explanation:

[tex] \red{\frak{Given}} \begin{cases} & \sf {13\ cos \theta\ -\ 5\ =\ 0\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \big\lgroup Can\ also\ be\ written\ as \big\rgroup} \\ & \sf {cos \theta\ =\ {\footnotesize{\dfrac{5}{13}}}} \end{cases}[/tex]

Here, we're asked to find out the value of (sinθ + cosθ)/(sinθ - cosθ), when 13 cosθ - 5 = 0. In order to find the solution we're gonna use trigonometric ratios to find the value of sinθ and cosθ. Let us consider, a right angled triangle, say PQR.

Where,

As we know that, 13 cosθ - 5 = 0 which is stated in the question. So, it can also be written as cosθ = 5/13. As per the cosine ratio, we know that,

[tex] \rightarrow {\underline{\boxed{\red{\sf{cos \theta\ =\ \dfrac{Adjacent\ side}{Hypotenuse}}}}}} [/tex]

Since, we know that,

So, we will find the PQ (Opposite side) in order to estimate the value of sinθ. So, by using the Pythagoras Theorem, we will find the PQ.

Therefore,

[tex] \red \bigstar {\underline{\underline{\pmb{\sf{According\ to\ Question:-}}}}} [/tex]

[tex]\rule{200}{3}[/tex]

[tex] \sf \dashrightarrow {(PQ)^2\ +\ (QR)^2\ =\ (RP)^2} \\ \\ \\ \sf \dashrightarrow {(PQ)^2\ +\ (5)^2\ =\ (13)^2} \\ \\ \\ \sf \dashrightarrow {(PQ)^2\ +\ 25\ =\ 169} \\ \\ \\ \sf \dashrightarrow {(PQ)^2\ =\ 169\ -\ 25} \\ \\ \\ \sf \dashrightarrow {(PQ)^2\ =\ 144} \\ \\ \\ \sf \dashrightarrow {PQ\ =\ \sqrt{144}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{PQ\ (Opposite\ side)\ =\ 12}}}}_{\sf \blue{\tiny{Required\ value}}}} [/tex]

∴ Hence, the value of PQ (Opposite side) is 12. Now, in order to determine it's value, we will use the sine ratio.

[tex] \rightarrow {\underline{\boxed{\red{\sf{sin \theta\ =\ \dfrac{Opposite\ side}{Hypotenuse}}}}}} [/tex]

Where,

Therefore,

[tex] \sf \rightarrow {sin \theta\ =\ \dfrac{12}{13}} [/tex]

Now, we have the values of sinθ and cosθ, that are 12/13 and 5/13 respectively. Now, finally we will find out the value of the following.

[tex] \rightarrow {\underline{\boxed{\red{\sf{\dfrac{sin \theta\ +\ cos \theta}{sin \theta\ -\ cos \theta}}}}}} [/tex]

[tex]\rule{200}{3}[/tex]

[tex] \sf \dashrightarrow {\dfrac{sin \theta\ +\ cos \theta}{sin \theta\ -\ cos \theta}\ =\ {\footnotesize{\dfrac{\Big( \dfrac{12}{13}\ +\ \dfrac{5}{13} \Big)}{\Big( \dfrac{12}{13}\ -\ \dfrac{5}{13} \Big)}}}} \\ \\ \\ \sf \dashrightarrow {\dfrac{sin \theta\ +\ cos \theta}{sin \theta\ -\ cos \theta}\ =\ {\footnotesize{\dfrac{\dfrac{17}{13}}{\dfrac{7}{13}}}}} \\ \\ \\ \sf \dashrightarrow {\dfrac{sin \theta\ +\ cos \theta}{sin \theta\ -\ cos \theta}\ =\ \dfrac{17}{13} \times \dfrac{13}{7}} \\ \\ \\ \sf \dashrightarrow {\dfrac{sin \theta\ +\ cos \theta}{sin \theta\ -\ cos \theta}\ =\ \dfrac{17}{\cancel{13}} \times \dfrac{\cancel{13}}{7}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{\dfrac{sin \theta\ +\ cos \theta}{sin \theta\ -\ cos \theta}\ =\ \dfrac{17}{7}}}}}_{\sf \blue{\tiny{Required\ value}}}} [/tex]

∴ Hence, the required answer is 17/7.

Answer:V≈3015.93

Step-by-step explanation:this is the answer

Step-by-step explanation:

5÷3=5/3 .The Numerator is > Denominator. So the fraction 5/3 is an Improper Fraction.

So the Proper Factored Form=1+2/3=1 2/3.

In fact 1 2/3 is a Mixed Fraction. But since its Numerator 2 < Denominator 3 ( of the Factional part)

The mathematical interpretation of "what fraction of 5 is 3?" is 5/3

First, we need to identify the numerator and the denominator

The numerator is the number on top of a fraction

The denominator is the number beneath a fraction

Since 3 is said to be a fraction of 5:

The numerator = 5

The denominator = 3

Fraction = Numerator / Denominator

Fraction = 5/3

Therefore, the mathematical interpretation of "what fraction of 5 is 3?" is 5/3

2 solutions because they is solution to it

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

Given data

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

Answer:

First part: k=2

Second part: a=1

Third part: b=2 c=-1 d=-2

Forth part: x^2-x-12

Step-by-step explanation:

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.

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° )

Answer:

The mean is basically the average.

In order to find avergae you add up all the given numbers and then divide it by the amount of given numbers.

in this case…

5 + 10 + 8 + 9 + 9 +9 = 50

There are 6 given values, which are 5, 10, 8, 9, 9, 9.

Answer:

hello

15 x² + 100 x - 70 - 17 x + 6 x²

=  9 x² + 83 x - 70

9 x² + 83 x - 70 = 0

Δ = 83 ² - 4 ( 9 * - 70 ) = 6 889 + 2 520 = 9 409 = 97 ²

x 1  = ( - 83 - 97 ) / 18 = -  180/18 = - 10

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

Step-by-step explanation:

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.
