Answer:

adjacent, complementary is your answer ☺️☺️☺️

Answer:

Adjacent

Step-by-step explanation:

These angles are adjacent because they share the same vertex

Answer:

David is 1.94 meters tall.

Given that,

Shaun is 1.88 meters tall.

David is stated to be 6 centimeters taller than Shaun.

To determine David's height, we need to add the additional height to Shaun's height.

Since there are 100 centimeters in a meter, we can convert the 6 centimeters to meters by dividing it by 100: 6 cm / 100 = 0.06 meters.

Now, we can add this height to Shaun's height to find David's height:

1.88 meters + 0.06 meters = 1.94 meters.

Therefore, David is 1.94 meters tall.

Here is my answer. I hope this is helpful.

The required values of x and y are x = -2 and y = 7 in parallelogram PQRS.

To find the values of x and y, we can use the fact that the diagonals of a parallelogram bisect each other. This means that the line segment PT is equal to half of the diagonal PR, and the line segment QT is equal to half of the diagonal QS.

We can set up two equations to represent this information:

PT = 1/2 × PR

QT = 1/2 × QS

Since we are given the lengths of PT and QT, we can substitute those values into the equations:

y = 1/2 × PR

2y = 1/2 × QS

We can then use the fact that the opposite sides of a parallelogram have equal lengths to find the values of PR and QS:

PR = PT + TR = y + (4x + 1)

QS = QT + TS = 2y + (3x + 12)

Substituting these values into the equations above, we get:

y = 1/2 × (y + (4x + 1))

2y = 1/2 × (2y + (3x + 12))

Solving these equations simultaneously will give us the values of x and y.

First, we can solve the second equation for y:

y = (1/2) × (2y + (3x + 12))

y = y + (3x + 12)/2

0 = 3x + 12/2

0 = 3x + 6

-6 = 3x

x = -2

Substituting this value of x into the first equation, we can solve for y:

y = 1/2 * (y + (-2 * 4 + 1))

y = 1/2 * (y - 7)

2y = y - 7

y = 7

Therefore, the values of x and y are x = -2 and y = 7.

Answer:

I would assume you meant that each cup serving = 1 cup.

So the answer would be 13 cup servings.

If it is a different number, such as cup serving = 1/2 cup, then 26 cup servings would be the answer.

The first term is,  9v2  its coefficient is  9 .

The middle term is,  -9v  its coefficient is  -9 .

The last term, "the constant", is  -1  

Step-1 : Multiply the coefficient of the first term by the constant   9 • -1 = -9  

Step-2 : Find two factors of  -9  whose sum equals the coefficient of the middle term, which is   -9 .

The length of ladder would be,

⇒ 14/√3 feet

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

You leaned the ladder against your house at a 30° angle of elevation.

And, The foot of the ladder is 7 feet from the foot of the house.

Now,

Let the length of ladder = x

Hence, We can formulate;

⇒ cos 30° = 7 / x

⇒ √3 / 2 = 7 / x

⇒ x = 14 / √3 feet

Thus, The length of ladder would be,

⇒ 14/√3 feet

Answer:

Answer:

$260,000

Step-by-step explanation:

Explanation:

Given the problem above, we solve for original value

Hence, in this case, we are given

percentage (35%) and the New Value ($351,000).

We can substitute this into the formula and solve for X

Let X be the original price, Hence, X = 100%

Therefore, $351000 = 135%

Divide both sides by 135

351000÷ 135 = 135÷135

2600 = 1%

Multiply both sides by 100

2600 * 100 = 1% * 100

$260000 = 100% = X

Hence, final answer is $260000

not going to lie, i was a little confused in the wording for this problem but im guessing the problem is asking for how much books is she reading in one month? ( im sorry if i read that wrong!! )

answer:

1 1/2 books

step-by-step explanation:

all you really need to do is dividing for this whole problem ( and you going to need to add/multiply if you wanted to double check )

first lets divide 12 and 8 by 4

12/4

= 3 books

8/4

= 2 months

now we just need to divide each problem by 2

3/2

= 1.5 or 1 1/2 books

2/2

= 1 month

because we dont need to round 1.5 to the nearest whole number, our answer is 1.5 books in 1 month

Answer:

D. 8[tex]\sqrt{2}[/tex]

Step-by-step explanation:

To find the diagonal of the square, you can use the Pythagorean theorem* to find the hypotenuse since the diagonal cuts the square into two right triangles with legs of 8 units in length:

If in a^2 + b^2 = c^2, a = 8 and b = 8,

8^2 + 8^2 = c^2 (put 8 as both the leg lengths in the equation)

128 = c^2 (calculate 8^2 and then add the two terms together)

c = 8[tex]\sqrt{2}[/tex] (square both sides)

So, the length of the diagonal is 8[tex]\sqrt{2}[/tex] units

*the Pythagorean theorem is a theorem used to find the sides lengths of a right triangle: a^2 + b^2 = c^2. a and b are the legs of the triangle, and c is the hypotenuse.
