When only three sides are provided without any information regarding the angle, such as a = 5 m and b = 9 m, c = 6m we can either create no triangle or create an unique triangle. Hence, either 0 or 1 Triangle.

For example :

How many different triangles may be formed with side lengths of 5m,9m and 6 m ?

Create a triangle with the following measurements: 5 meters, 9 meters , and 6meters, by protractor-adjusted to the given length of sides. You have constructed a triangle.

We can only create one triangle here, as no choice can be made in the given length of side as they are prefixed.

This implies that you cannot chose the side length independently. So, only one triangle which is unique will be formed. Hence, 0 or 1 triangle is formed

The coordinate of the midpoint of JP is -1

On the number line, we have the following coordinates

J = -7

P = 5

The coordinate of the midpoint of JP is calculated using

Midpoint = 1/2 * (J + P)

This gives

Midpoint = 1/2 * (-7 + 5)

Evaluate the sum

Midpoint = 1/2 * -2

Evaluate the product

Midpoint = -1

Hence, the coordinate of the midpoint of JP is -1

We have to add 35 ounces of water to the mixture to make the proportion of medicine and water same as the original mixture.

Given,

The quantity of medicine added to the original mixture = 15 ounces

New quantity of medicine in the mixture = 18 ounces

Quantity of water in the mixture = 7 ounces

Total new quantity of mixture = 18 + 7 = 25 ounces

Original quantity of medicine in the mixture = 18 - 15 = 3 ounces

Original quantity of water in the mixture = 7 ounces

Total original quantity of mixture = 3 + 7 = 10 ounces

We have to find the amount of water to add into the new mixture to make the proportion of medicine and water same as the original mixture.

Here,

Proportion of medicine and water in original mixture = 3:7

Quantity of medicine and water in new mixture = 18:7

Now,

18 ÷ 3 = 6

Then, 7 × 6 = 42

So, 42 - 7 = 35

Therefore, we have to add 35 ounces of water to the mixture to make the proportion of medicine and water same as the original mixture.

Answer:12+2y

Step-by-step explanation:

Answer:

12 + 2y

Hope this helps :)

Step-by-step explanation:

When it says "sum," this means the answer to 2 numbers you add. The first number would be 12, and the other number will be y 2 times. So y plus y equals 2y. The final equation is 12 + 2y.

Answer:

13

Step-by-step explanation:

first use PEMDAS= P= Parentheses E= Exponents M= Multiplication D= Division A= Addiction S= Subtraction.

(3+6)+6-2=

9+6-2=

15-2=

13

Add 3+6 which is 9

Add 3+6 which is 9then add 9+6 equal to 15

Add 3+6 which is 9then add 9+6 equal to 15finally subtract 2 from 15

Add 3+6 which is 9then add 9+6 equal to 15finally subtract 2 from 15boom that's how you do it

Answer:

22

Step-by-step explanation:

Use Pemdas

P means parenthesis so add the numbers in the parenthesis

3 + 6 = 9

2(9) + 6 - 2 =

Next is E, but there are no exponents so now there is M

multiply 2 times 9, you will get 18.

18 + 6 - 2 =

So next is A which is addition, add 18 + 6

18 + 6 = 24.

24 - 2

And lastly, S which is subtraction.

24 - 2 = 22

So the answer is 22

Answer:

The first 2 and the 2nd to last equations

Step-by-step explanation:

Angles 8 and 10 are alternate interiors, which would only work if m and n are parallel.

Angles 1 and 9 are congruent angles, which would only work if m and n are parallel.

Angle 1 and 3 are on the same line, so that can't prove it.

m8 and m9 could only add up to 180 if m and n are parallel, which makes this also true.

Angles 7 and 10 add up to 180, but can't be congruent.

Answer:

-2/5

Step-by-step explanation:

Hi there!

We find slope by using rise over run.

For this problem, identify two points on the line. I'll use (0, 3) and (5, 1).

[tex] m = \frac{{y} - {y} }{ {x} - {x}}[/tex]

You can plug the coordinates into this formula, making sure they stay in the right order. Subtract the first y coordinate from the second y coordinate, and the first x coordinate from the second x coordinate. (Just make sure one point is on the left, and the other on the right).

[tex] \frac{3 - 1}{0 - 5} = \frac{2}{ - 5} [/tex]

2/-5 is the same as -2/5, so that is your answer

Using least common multiple (LCM), the Vasquez family both visit their grandmother and host the neighbor hood party after 24 weeks. After 48 weeks, all three events will occur at the same time.

A common multiple is defined as a whole number, that is a shared multiple of each set of numbers. The least common multiple (LCM) of two integers is the smallest positive integer that is divisible by both numbers.

If the Vasquez family visit their grandmother every 3 weeks and host a neighbor hood party every 8 weeks, to know when will these event will occur at the same time, solve for the LCM of 3 and 8.

3 : 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, . . .

8 : 8, 16, 24, 32, 40, . . .

LCM = 24

Hence, after 24 weeks, both will occur at the same time.

To know when will the three events will occur at the same time, solve for their LCM.

3 : 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, . . .

8 : 8, 16, 24, 32, 40, 48, . . .

16 : 16, 32, 48, . . .

LCM = 48

Answer:

Step-by-step explanation:

Rate: 54000 brochures per hour

Formula: D=RT   Distance=Rate x Time (In this case distance is the amount)
(I’m not sure if you meant to type 3 1/4 or 314. I’ll include both)
D=54,000(3 1/4)

Two ways

1. 54,000(3 1/4)=175,500

2. 54,000x3 is 162,000, and 1/4 of 54,000 is 54,000/4=13,500. 162,000+13,500=175,500.

(54,000 x 314 = 16,956,000)

The distance between each pair of parallel lines with the given equations y = -2x+1 and y = -2x+16 is 15 units.

We can find the points passing through the lines.

Hence,

The points passing through the line y = x - 11  are:-

Let x = 0

y = -2(0) +1

(0,1)

and;

Let x = 1/2

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

(-1/2,0)

The points passing through the line y = -2x + 16 are:-

Let x = 0

y = -2(0) + 16 =16

(0,16)

and;

Let x = 8

y = -2(8) + 16 = -16 + 16

(8,0)

Hence, using distance formula, the distance between the parallel lines will be:-

[tex]\sqrt{(16-1)^2+(0-0)^2} = \sqrt{15^2+0}=\sqrt{225} = 15[/tex] units.

To form a system with an infinite number of solutions, the equation -4x + 6y = 3 must be combined with D. 0.75 + x = 1.5 y.

A system of equations is a set of two or more equations which includes common variables.

To form a system with an infinite number of solutions, the lines should be the same or overlapping. These lines must have the same slope and y-intercept. The equations of these lines must be the multiple of one another.

Given the equation -4x + 6y = 3, rewrite this in the form c + ax = by(same as the form of the choices).

-4x + 6y = 3   ⇒   3 + 4x = 6y

To make 6y into 1.5y, divide both sides by 4.

3 + 4x = 6y   ⇒   0.75 + x = 1.5 y

Hence, the equation -4x + 6y = 3 must be combined with 0.75 + x = 1.5 y to form a system with an infinite number of solutions.
