Answers

Answer 1
A, C, D
The slopes might be the same
All right triangles are congruent,
The corresponding parts or congruent triangles are congruent

Answer 2

"sides ln and np have the same slope." and "sides lm and mn are proportional to sides no and op." are correct for Triangle lmn is similar to triangle nop. both are right triangles.

What are Similar Triangles?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

"Congruent" means the same

Two triangles are said to be congruent if they both have same length and same angles.

"Similar" means the area and sides will be proportional, it means when we divide or multiply with a number we get the measure of the other.

If triangle lmn is similar to triangle nop. both are right triangles.

Then we need to check which options will be correct and holds.

a. sides ln and np have the same slope it is correct because the triangle will have same slopes

b. It must not be true "sides ln and np are congruent" because as they are congruent the sides should be same.

c.  triangle lmn and nop are congruent, is not true because there measures are different.

d. As the triangles are similar " sides lm and mn are proportional to sides no and op." must be true, because of proportionality.

Hence "sides ln and np have the same slope." and "sides lm and mn are proportional to sides no and op." are correct for Triangle lmn is similar to triangle nop. both are right triangles.

How many subsets of exactly two elements does a set of five elements have?
A.10
B.26
C.7
D.32

Answers

Answer:

Option: A is the correct answer.

                A. 10

Step-by-step explanation:

We know that the number of subsets of exactly ''r'' elements that is formed by the help of n elements is calculated by:

            [tex]n_C_r[/tex]

Since here we have to chose 2 elements out of the 5 elements in order to form a subset.

Hence, we have:   n=5 and r=2

Hence, the number of subsets are:

[tex]5_C_2=\dfrac{5!}{2!\times (5-2)!}\\\\\\5_C_2=\dfrac{5!}{3!\times 2!}\\\\\\5_C_2=10[/tex]

Hence, the number of subsets are:

How to solve a multiplication problem with a variable?

Answers

In order to move a number that is multiplied or divided by the variable, you must do the inverse to both sides. That means, if the number is multiplied, you must divide it by both sides. If it's divided, you must multiply it by both side. steps so that you can apply them to more complex problems.

Example Question: 6x + 4 = 22

The goal in this is to get the variable alone and these are the steps how to. What you have to do is subtract 4 from 4 so that you can get 6x alone. But when you subtract 4 from one side, you have to subtract 4 from the other side too which leaves us with 6x = 18. Now, we have to do the opposite of multiplication which is division. So we are going to do 6x divided by 6 and the two sixes cancel each other out. But remember, if you do something to one side you have to do it to the other as well. So we have to do 18/6 which leaves us with the answer.

Kitty Kibbles has a higher unit price of $1.50 /pound.

Feline Flavor has a higher unit price of $1.50 /pound.

Answers

Kitty Kibbles has a higher unit price of $1.50 / pound
Answer:

The statement which is true about the unit price is:

Kitty Kibbles has a higher unit price of $1.50 /pound.Step-by-step explanation:A 16 -pound bag of Kitty Kibbles is $24.00 .

i.e.

16 pound cost= $ 24

Hence,

cost of 1 pound= $ (24/16)

                         = $ 1.50

i.e. unit price of Kitty Kibbles is: $ 1.50

Also,

An 8 -pound bag of Feline Flavor is $11.20

i.e. cost of 8 pound of Feline Flavor= $ 11.20

cost of 1 pound of Feline Flavor= $ (11.20/8)

                                                    = $ 1.40

Hence,  unit price of Feline Flavor is: $ 1.40

The measure of an angle is 79°. what is the measure of a supplementary angle?

What are the angles?

Angles are an integral facet in the study of mathematics, particularly geometry. Angles are formed by two rays (or lines) that begin at the same point or share the same endpoint.

The point at which the two rays meet (intersect) is called the vertex.

Here given that,

The measure of an angle is [tex]79[/tex] degree.

Let the supplement angle is [tex]x[/tex]

As we know that the supplement of an angle is [tex]180-x[/tex].

https://brainly.com/question/15277238

#SPJ5

Final answer:

The measure of a supplementary angle to one that measures 79° is 101°, since supplementary angles sum up to 180°.

Explanation:

If the measure of an angle is 79°, the measure of a supplementary angle can be found by subtracting this angle from the total degrees in a straight line. In other words, the sum of the measures of supplementary angles is 180°. Therefore, to find the measure of a supplementary angle when one angle measures 79°, we perform the following calculation:

180° - 79° = 101°

So, the measure of the supplementary angle is 101°.

You know the whole and one part you can blank to find the other part sum or subtract

Answers

You can subtract to find the other part

We can find the other part by subtracting the known part from the whole.

If we know the whole and one part, we can find the missing part by subtracting the known part from the whole.

Suppose we have a whole number of 12 and we know one part is 5.

To find the other part:

12 - 5 = 7

So, in this case, the missing part will be 7.

Therefore, we can find the other part by subtracting the known part from the whole.

Find the number of ways 4 members from a family of 5 can line up for a photo shoot?

Answers

they can line up 20 different ways

Final answer:

There are 120 different ways for 4 members out of a family of 5 to line up for a photo shoot. This is calculated using permutations, where the order of members matters, and is found by the formula 5! / (5-4)!.

Explanation:

To find the number of ways 4 members from a family of 5 can line up for a photo shoot, we use the concept of permutations since the order of arrangement matters.

In mathematics, the number of permutations for selecting r objects from a set of n objects is given by nPr, which is calculated as n! (n factorial) divided by (n-r)! (the factorial of the difference between n and r).

In this case, we want to arrange 4 out of 5 family members, so n = 5 and r = 4. The permutation formula gives us:

5P4 = 5! / (5-4)! = (5 × 4 × 3 × 2 × 1) / 1 = 120 ways.

Therefore, there are 120 different ways for 4 members out of a family of 5 to line up for a photo shoot.

Angle PJK and Angle DJB are vertical angles. They are formed when you cross PD and KB. They are opposite one another. Vertical angles are congruent, so,

(angle PJK) = (angle DJB)
3x-40 = 2x-10
3x-40-2x = 2x-10-2x ... subtract 2x from both sides
x-40 = -10
x-40+40 = -10+40 .... add 40 to both sides
x = 30

Side Note:
if x = 30, then angle PJK is...
angle PJK = 3x-40
angle PJK = 3*x-40
angle PJK = 3*30-40
angle PJK = 90-40
angle PJK = 50 degrees
which is also the measure of angle DJB

Explanation:

Marta is likely incorrect because her equation has a positive y-intercept, but the scatterplot suggests a negative y-intercept. The y-intercept is the value of y when x equals zero, so if the scatterplot shows a negative y-intercept, it means that when x is zero, y is negative.
