Solve for x

Answers

Answer:

x = 54

Step-by-step explanation:

These angles are complementary because they add up to 90:

x - 7 + 43 = 90

x + 36 = 90

x = 90 - 36

x = 54

Answer:

54

Step-by-step explanation:

Since the total of the two degrees makes a right angle, we know that the unknown degree has to be 47

Knowing this, we can add 7 to this. (This is the inverse of subtracting to eliminate 7)

47 + 7 = 54

So x = 54

We can verify by solving replacing x.

(54 - 7) = 47

47 + 43 = 90

Answers

Answer:

I believe x = 12

Step-by-step explanation:

If the triangles were similar then they would have the same angle measures.

Steps:

Add angle K and L: 90 + 54 = 144

Subtract the added angles from 180 to find angle J: 180 - 144 = 36

Angle J is similar to angle X so, divide 36 by 3: 36/3 = 12

x = 12

9.) I 5/14 * 4/13 10.) H 45

Step-by-step explanation:

For 9.) the probability the first time to get a red marble is 5/14 because there are 5 red marbles and 14 total marbles. The probability the second time she picks, if a green one was chosen, one is 4/13 because one green marble needs to be missing and because one marble is missing 14-1=13 so there are 13 total marbles. You would multiply the two probability (5/14 and 4/13) to find the probability of drawing two green marbles in a row

For 10.) I found that 2/5= .4 and 5/8= .625 so I multiplied both fractions by 200

.4 * 200= 80

.625 * 200= 125

These are the numbers of games both people won

Subtract the two and you get 125-80= 45 which is how many more games Tyrell would win.

-8x + 3y = -33
y = -5x + 35

Answers

Answer:

x = 6  y = 5

Step-by-step explanation:

-8x + 3y = -33

y = -5x +35

-8x + 3(-5x + 35) = -33

-8x - 15x + 105 = -33

-23x + 105 = -33

-23x = -138

x = 6

-8(6) + 3y = -33

-48 + 3y = -33

3y = 15

y = 5

Cheddar cheese costs $4.25 per pound. Write an equation best represents y, the total cost of x pounds of cheddar cheese and type out your reason (justify) for your answer.

How do i find the answer??

Answers

Answer:

y=4.25x

Step-by-step explanation:

x will represent the number of pounds of cheddar that you have. so whatever the value of X is, 4.25 would be multiplied by X. This problem does not provide a value for x, but say you had 4 pounds of cheese (x=4), the problem would become y=4.25(4) because you would plug 4 in where x is.

4.25(4)= 17 and therefore Y would equal 17.

What are the advantages of taking a random sample instead of surveying an entire population?

Answers

Answer:

Answer is below

Step-by-step explanation:

Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. Selecting subjects completely at random from the larger population also yields a sample that is representative of the group being studied. This provides lack of bias towards the subject of the survey. It's overall more efficient, faster, and pushes the idea of simplicity through surveys.

Answer:

Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. It offers a chance to perform data analysis that has less risk of carrying an error. ... There is an equal chance of selection. ... It requires less knowledge to complete the research. ...
