triangle MKL is an isosceles triangle with MK congruent to ML. If Mk=7x-15, KL=4x-5, and ML=10x-42, find x and the measure of each side

Answers

Answer 1
Answer:

Answer:

For given isosceles triangle ΔMKL with MK≅ML, x=9; MK=48, KL=31, ML=48.

Explanation:

An isosceles triangle has two of its 3 sides congruent.

For given ΔMKL, MK is congruent to ML (MK ≅ ML); i.e. length of side MK is equal to length of the side ML.

Given:

MK=7x-15

KL=4x-5

ML=10x-42

Equating MK with ML, we get:

MK=ML

7x-15 = 10x-42

Taking all x terms to the right,

42-15 = 10x-7x

27 = 3x

x=9

To find measure of each side MK, ML and KL; substitute the value of x=9 in corresponding equations.

MK = 7x-15  

= (7×9) - 15

= 63-15  

= 48

KL = 4x-5

= (4×9)-5

= 36-5

= 31

ML = 10x-42

= (10×9)-42

= 90-42

= 48

Therefore, for given ΔMKL with MK≅ML, x=9; MK=48, KL=31, ML=48.

A carnival has a duck pond booth. You choose a rubber duck at random. The mark on the bottom of the duck tells you whether you won a small, medium, or large prize, or no prize at all. There are 65 ducks floating in the pond. There are 3 marked as large-prize winners, 13 ducks marked as medium-prize winners, and 21 ducks marked as small-prize winners. Find the theoretical probability of winning a medium prize at the duck pond. Express your answer as a decimal. If necessary, round your answer to the nearest thousandth.0.2

Answers

The theoretical probability of winning a medium prize at the duck pond is 0.2, Hence option A is correct.

What is probability?

Probability is the ratio of number of favorable outcomes and total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.

According to the given information,

Number of medium-prize winning ducks = 13

The total number of ducks = 65

The theoretical probability of winning a medium prize at the duck pond can be found by dividing the number of medium-prize winning ducks (13) by the total number of ducks (65).

So, the probability of winning a medium prize is,

= 13/65

= 0.2 or 20%

Therefore, the theoretical probability of winning a medium prize at the duck pond is 0.2 or 20%.

Hi there! :)  I believe the answer is 0.2. The way I got 0.2 is because there are 13 medium-sized ducks and there are 65 total ducks floating I did 13/65( 13 divided by 65) which equals 0.2. For theoretical probability you divide by the number of outcomes.

a ferris wheel can accommodate 50 people in 20 minutes.How many people could ride the firris wheel in 4 hours?

Answers

So first, find out how many people can ride in an hour.
50x3=150 people
20x3=60 minutes
Then multiply by 4.
150x4=600 people
60x4=240 minutes (4 hours)
In 4 hours, 600 people can ride the ferris wheel.

Step-by-step explanation:

Your dog is 16 years old in dog years. Your cat is 28 years old in cat years. For every human year, your dog ages by 7 dog years and your cat ages by 4 cat years. In how many human years will both pets be the same age in their respective types of years?

Answers

This question is based on the concept of graphical method. Therefore, In 4 years,  human years will both pets be the same age in their respective types of years.

Given:

Your dog is 16 years old in dog years.

Your cat is 28 years old in cat years.

For every human year, your dog ages by 7 dog years and your cat ages by 4 cat years.

Let x be the no. of human yrs.

We have to find x such that age is same for dog and cat in their respective year i.e.

16 + 7x = 28 + 4x

Write above equation as follows and solve it graphically,

y = 16 + 7x

y = 28 + 4x

From the graph, it is observe that. Attachment is below.

Point of intersection is (4, 44). Thus, solution of equation is x =4.

Now put the value x = 4 in  equation 16 + 7x = 28 + 4x.

We get,

16 + 7(4) = 28 + 4(4)

44 = 44

Therefore, In 4 years,  human years will both pets be the same age in their respective types of years.

Is 351,800 bigger than 605,908

Answers

Hey there! Let me help you out!

No, this is not true. The answer to your question is: 351800<605908. This means that 605908 is bigger than 351800. To find this out, count how many digits there are in both the numbers. The number with more digits is bigger than the other number. If both the numbers have the same number of digits, then see the starting number of each number and so forth, if they are the same. For example, for this question, count how many numbers there are in each number. They both have 6 numbers so u can't make out anything from that. Next see the starting number for each of them. In 351800, the starting number is 3. In 605908, the starting number is 6. Since 6 is larger than three, 605908 is bigger than 351,800.

When solving an equation using the distributive property that involves distributing fractions, usually the first step is to multiply by the LCD to eliminate the fractions in order to simplify computation. Is it necessary to do this to solve 1/4(5x+6)=1/3(9x-24)? Why or why not?

Answers

It's not necessary, but it makes solving quicker, and more efficient. You'd have to find the LCD at some point, and doing it at the beginning helps you to not encounter as many errors as you would otherwise
