pshichka [43]3 years ago

6 0

Answer:

Right, Isosceles

Step-by-step explanation:

The side lengths of this triangle : 2√8 2√5 2√5

Scalane triangle has all side lengths in different measure but in this triangle we have two side lengths equal

Right triangle has a right angle with 90° and the square measure of hypotenuse is equal to sum of the square length of two side lengths in this triangle since 2√5 + 2√5 = 2√8 we can say that this is a right triangle.

Isosceles triangle are triangles with two side lengths equal to each other

Equilateral triangles are triangles with all side lengths equal to each other but we know one of the side length in this triangle is different

so the answer is Right and Isosceles.

Sandra is a realtor. She makes a 4.5% commission on the value of the houses she sells. If Sandra sold $250,000

zalisa [80]

Answer:

$11250

Step-by-step explanation:

She makes a 4.5% commission on the value of the houses she sells. If Sandra sold $250,000 worth of houses.

We need to find how much she earn as her commission. Let it is x. We can calculate by finding 4.5% of $250,000. It is given by :

$x=\dfrac{4.5}{100}\times 250,000\\\\x=\$11250$

So, she will earn $11250 as her commission.

Adam has 10 blocks numbered 1 through 10. Which describes the probability of randomly choosing a block that has an even number?

Licemer1 [7]

Answer:

$\dfrac{1}{2}$

Step-by-step explanation:

Given that:

10 number of blocks which have numbers from 1 through 10.

To find:

Probability of randomly choosing a block that has an even number.

Solution:

The given set of numbers is: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

There are a total of 5 Even numbers are {2, 4, 6, 8, 10}.

And There are a total of 5 Odd number are {1, 3, 5, 7, 9}.

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Here, Event E is randomly choosing an even number.

Number of favorable cases = 5

Total number of cases = 10

Therefore, the required probability is:

$P(E) = \dfrac{5}{10}\\\Rightarrow P(E) = \dfrac{1}{2}$

How do I write Domain and Range in inequality notation?

ArbitrLikvidat [17]

Answer:

Domain: (-infinity, infinity) Range: (-infinity, infinity)

Step-by-step explanation:

They are parabolas, therefore you can assume that they go on infinitely. To find range, you must look at your y values. Look for your lowest point. Because the line goes done forever, your beginning mark would be (-infinity.

To find the other part, you look at your positive y values. Look for the highest value. Because this goes on infinitely, the completed version of your notation would be (-infinity, infinity). Be sure to use the infinity symbol though, which looks like an 8 rotated 90 degrees.

To find domain, look at your x values. To begin, look at your left-most values, which would be the negative numbers. Because the line goes on forever to the left, your notation would be (-infinity. To find the other part of domain, look at your positive x values. Because this line goes on infinitely as well, the completed version of your notation would be (-infinity, infinity). Infinity is never bracketed, it is always in parenthesis.

How to solve for a b and c

andrew-mc [135]

Answer:

a=40. b=140. c= 40

Step-by-step explanation:

b is congruent To 140 because of the vertical angles postulate that states two angles vertical from one another are congruent.

a is 40 because it is Supplementary to b Which means that the sum of a and b must add up to 180.

c is Congruent to a due to the vertical angles postulate
