Find the numbers whose sum is 9, if
three times the first number increased
by two times the second number
equals 22.

The triangle's angle and side relationships, the triangle's angles, from smallest to greatest, would be ∠L, ∠M, ∠K.

When two triangle angles are not equal, their opposite sides' measurements are also not equal, with the longer side being opposite the larger angle.

The greatest side and angle in every triangle are on opposing sides. The smallest side and smallest angle of any triangle are in opposition to one another. The mid-sized side and mid-sized angle in every triangle are in opposition to one another.

The longest side of a triangle is located across from the largest angle. In a triangle, the longest side is located across from the one with the least angle.

As a result, given the triangle's angle and side relationships, the triangle's angles, from smallest to greatest, would be: C. ∠L, ∠M, ∠K.

yes the length of the strawberry patch can be greater than 1 yard.

A rectangle is a quadrilateral with four sides and four right angles.

Given that Danah wants the area of her rectangular strawberry patch to be exactly 1 square yard.

We have to find out whether the length of the rectangular strawberry patch can have a value greater than 1.

Area of a rectangle = Length x Width.

The area of the rectangular strawberry patch is exactly 1 square yard.

Area  = 1 square yard

Length x Width = 1 square yard

To have the area of the rectangular strawberry patch be exactly 1 square yard.

We can have the following cases :

Case 1.

Length = 2 and Width = 0.5

Area = Length x Width = 2 x 0.5 = 1 square yard.

Case 2.

Length = 4 and width = 0.25

Area = Length x Width = 4 x 0.25 = 1 square yard.

Case 3.

Length = 8 and width = 0.125

Area = Length x Width = 8 x 0.125 = 1 square yard.

Case 4.

Length = 10 and width = 0.1

Area = Length x Width = 10 x 0.1 = 1 square yard.

We see that we can have the length as 2, 4, 8, and 20 in order to have an area of the rectangle as 1 square yard.

Hence, yes the length of the strawberry patch can be greater than 1 yard.

Step-by-step explanation:

Since ABCD is a parallelogram, AB∥DC and AD∥BC

Now, AB∥DC and transversal BD intersects them.

∴∠ABD=∠BDC since alternate angles are equal.

⇒10x=60∘

⇒x=1060∘=6∘

And, AD∥BC and transversal BD intersects them.

∴∠DBC=∠ADB

⇒4y=28∘

The solution to the system of two equations is (x,y) = (10, -25.5).

An equation is a mathematical statement that two expressions are equal. It is written in the form of an equality sign, which is a line with two dots on either side. The expressions on either side of the equality sign represent the same value. Equations are used to solve problems, compare quantities, and describe relationships between variables. In addition, equations are often used to describe physical laws and scientific theories.

To solve the system of equations, one must first isolate the variables by subtracting one of the equations from the other. Subtracting equation 1 from equation 2 results in equation 2 having x terms on one side and y terms on the other.

3x + 4y = 19
-5x - 2y = -1

--------------------------------
-2x = -20

Now, solve for x by dividing both sides by -2.

x = 10

Next, substitute x = 10 into equation 1 and solve for y.

5x + 2y = −1
5(10) + 2y = -1
50 + 2y = -1
2y = -51
y = -25.5

Therefore, the solution to the system of two equations is (x,y) = (10, -25.5).

No because the bike order does not meet the restrictions of[tex]4c+6a \le 120 \ \text{ and } \ 4c+4a \le 100\\\\[/tex]

===================================================

Explanation:

c = number of child bikes

a = number of adult bikes

Each child bike takes 4 hours to build. This means 4c represents the total time spent building all c number of child bikes. Eg: if c = 2, then 4c = 4*2 = 8 hours is spent total building these two child bikes.

Meanwhile, each adult bike takes 6 hours to build. That means 6a represents the total time spent building these subset of bikes.

The expression 4c+6a is the total time spent building all of the bikes, child and adult.

The company has 120 hours of building time. The total time (4c+6a) cannot exceed this 120 hour ceiling.

This is how we arrive at [tex]4c+6a \le 120[/tex] which is one of the constraints or restrictions.

------------------------------

Now onto the testing side of things.

Each child bike takes 4 hours to test. That gives us 4c.

Each adult bike takes 4 hours to test. We get 4a.

4c+4a = total testing time for all of the bikes

[tex]4c+4a \le 100[/tex] is the second restriction we place, since we have at most 100 hours of testing time total. We cannot exceed this.

------------------------------

To summarize so far:

Let's see if we can build c = 20 child bikes and a = 6 adult bikes

Plug this pair of values into the first inequality

[tex]4c+6a \le 120\\\\4*20+6*6 \le 120\\\\80+36 \le 120\\\\116 \le 120[/tex]

The last inequality is true, which means the inequality [tex]4c+6a \le 120[/tex] is also true for the values c = 20 and a = 6.

So far it looks like we can build these number of bikes.

But we need to check the other inequality.

[tex]4c+4a \le 100\\\\4*20+4*6 \le 100\\\\80+24 \le 100\\\\104 \le 100\\\\[/tex]

We run into a problem. The last inequality is false, which means [tex]4c+4a \le 100[/tex] is false when c = 20 and a = 6 are plugged into it.

Meaning it is impossible to test 20 child bikes and 6 adult bikes in a week.

This is why   choice  A   is the final answer.

The probability of selecting a custard-filled donut followed by a lemon-filled donut is:

P(custard, lemon) = P(custard) * P(lemon | custard)

P(custard, lemon) = (2/3) * (5/23)

P(custard, lemon) = 10

What is the probability?

Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, where 0 represents an impossible event, and 1 represents a certain event.

We can find the probability of selecting a custard-filled donut followed by a lemon-filled donut by multiplying the probability of selecting the first donut by the probability of selecting the second donut, given that the first donut was selected.

The probability of selecting a custard-filled donut is:

P(custard) = number of custard-filled donuts / total number of donuts

P(custard) = 16 / 24

P(custard) = 2/3

Given that a custard-filled donut was selected, the probability of selecting a lemon-filled donut next is:

P(lemon | custard) = number of lemon-filled donuts / total number of donuts remaining

P(lemon | custard) = 5 / (24-1) = 5/23

The probability of selecting a custard-filled donut followed by a lemon-filled donut is:

P(custard, lemon) = P(custard) * P(lemon | custard)

P(custard, lemon) = (2/3) * (5/23)

P(custard, lemon) = 10

To find the percent of the mixture that is water, we need to divide the amount of water present in the mixture by the total amount of liquid in the mixture, and then multiply by 100.

We know that the total amount of liquid in the mixture is 52 oz and 13 oz of it is pure alcohol, so the rest of it is water.

Water = 52 oz - 13 oz = 39 oz

So, the percentage of the mixture that is water is:

(Water / Total) x 100 = (39 / 52) x 100 = 75%

To find the percent of the mixture that is alcohol, we need to divide the amount of alcohol present in the mixture by the total amount of liquid in the mixture, and then multiply by 100.

So, the percentage of the mixture that is alcohol is:

The value of x in the isosceles triangle shown is √25/2, which simplifies to √52, √24 or √20.

Value is a term that can carry a variety of meanings, depending on the context in which it is used. Generally, value is an attribute of an object, idea, or belief that is seen as desirable or beneficial. In economics, value can refer to the amount of money something is worth, or the amount of goods or services that can be exchanged for it. In sociology, value can refer to a person's beliefs, morals, and customs. In mathematics, value can refer to a number or quantity.

In order to find the value of x in the isosceles triangle shown below, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle with sides a, b and c, a² + b² = c². In the triangle shown, two of the sides are equal, thus a = b. This means that the equation can be rearranged to a² + a² = c², which simplifies to 2a² = c². As the right angle side of the triangle is equal to 5, we can substitute it into the equation to get 2a² = 25. This equation can be further rearranged to a² = 25/2, or a = √25/2.

Therefore, the value of x in the isosceles triangle shown is √25/2, which simplifies to √52, √24 or √20.
