What Is The Value Of X?Enter Your Answer In The Box.x =

Answers

Answer 1

Answer:

x = 39

Step-by-step explanation:

all triangles have angle measures that add up to 180°.

This means that to find what x is, you add 102 and 39, and then subtract that from 180, so

180-(102+39) = x

180-141=x

39=x

Answer 2

Answer:

x° = 39°

Step-by-step explanation:

According to the angle sum property of triangles, the 3 angles in a triangle will sum up to 180°.

102° + 39° + x° = 180°

141° + x° = 180°

x° = 180° - 141°

x° = 39°

A store sells 4 cans for ​$11. what is the price of 9 cans​?

Answers

Answer:

24.75

-------------------------------------------------------------------------------------------------------------

Solve

Since the customers pay 11 dollars for 4 cans, first find how much one can costs by dividing the cost of 4 cans by the amount of cans given.

[tex]11 / 4 = 2.75\[/tex]

Now that we know they're paying 2.75$, multiply 2.75 by 9 to find the result.

[tex]2.75 * 9 = 24.75\[/tex]

That said, the answer is 24.75$

Answer:

Dafna makes sport jackets. she is paid d dollars per hour , plus a piece rate of p dollars for each jacket .last week she made j jacket in h hours . write an expression for her total earnings .

Answers

Cost price is the total amount paid for the jacket while the selling price is the amount they are sold. The expression for her total earning willbe t(d) = hd - jp

Calculating total earning

Cost price is the total amount paid for the jacket while the selling price is the amount they are sold.

Total earning = Selling price  - Cost price

Find the cost price

If Dafna makes sport jackets and she is paid d dollars per hour, plus a piece rate of p dollars for each jacket.

Cost price = hd

x is the number of hour

Selling price = jp

total earning = hd - jp

Hence the expression for her total earning willbe t(d) = hd - jp

Answer:

C. 4 2/3

Step-by-step explanation:

1) Use this rule: a/b * c = ac/b.

7 * 6/9

2)  Simplify 7 * 6 to 42.

42/9

3) Simplify.

4) Convert to mixed fractin form.

4 2/3

Answer:

The product of 7/9 and 6:

[tex]\\7/9 x 6 \\\\7x6=42\\\\42/9\\4 6/9\\\\4 is the whole number\\6/9 is the fraction that if we remove the 3 from both of us, it gives us the result 2/3\\ The answer is the B \\[/tex]

Step-by-step explanation:

the answer is the B

Because You only had to multiply 6 by 7 and the result, which would be 42 over 9, should be converted to a mixed number, which would be dividing 42 by 9, which is 4, and us over 6, which is four, which is the whole number, and 6 is the numerator and you don't change the nine since it is still the denominator.

Because the 4 is the whole number

And 6/9 is the fraction that if were move the 3 from both of us , it gives us the result is 2/3

So we have 4 2/3

the answer is the B

Maggie takes three electives: art, Spanish, and creative writing. She calculated the mean absolute deviation of the points she earned throughout the year in each class.


art: mean absolute deviation of 2. 1


Spanish: mean absolute deviation of 0. 8


creative writing: mean absolute deviation of 2. 7


In which elective were her scores the most spread out?

Answers

Due to the higher value of the mean absolute deviation, her scores were most spread out in creative writing.

What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean. Hence, a higher value of the mean absolute deviation means that the data-set is more spread out.

In this problem, creative writing has the highest mean absolute deviation, hence, it is the elective in which her scores were most spread out.

Boston Red Sox?
Write your answer as a fraction or whole number.
P(Boston Red Sox) =
Submit

Answers

Answer:

P(Boston Red Sox) = 2/5

Step-by-step explanation:

The probability that the favorite team of a randomly selected baseball fan is the Boston Red Sox can be found by dividing the number of Boston Red Sox fans by the total number of fans.

It's given that there are 12 Boston Red Sox fans and 18 other fans. Therefore the total number of fans is 12 + 18 = 30.

If we divide the number of Boston Red Sox fans by the total number of fans, we get 12/30 = 2/5. Finally, we have P(Boston Red Sox) = 2/5.


Find four consecutive odd integers such that if the sum of the first and fourth is multiplied by three, the result
is 12 less than four times the third.

Answers

Answer:

-7, -5, -3, -1

Step-by-step explanation:

Let x be the smallest of the four consecutive odd integers. Then the next three consecutive odd integers are x+2, x+4, and x+6. We have:

[tex]3(x + x + 6) = 4(x + 4) - 12[/tex]

[tex]3(2x + 6) = 4(x + 4) - 12[/tex]

[tex]6x + 18 = 4x + 16 - 12[/tex]

[tex]6x + 18 = 4x + 4[/tex]

[tex]2x = - 14[/tex]

[tex]x = - 7[/tex]

So the four consecutive odd integers are -7, -5, -3, and -1.

Solving for x in ΔLMN

6x + 3 + 4x - 10 + 5x + 7 = 18015x = 180x = 12

Angles in ΔLMN

(6x + 3)° = 6(12) + 3 = 75°(4x - 10)° = 4(12) - 10 = 38°(5x + 7)° = 5(12) + 7 = 67°

Solving for y in ΔSTU

5x + 3y + 9y - 7 + 6x - 5 = 18011x + 12y - 12 = 18011(12) + 12y = 192132 + 12y = 19212y = 60y = 5

Angles in ΔSTU

(5x + 3y)° = 5(12) + 3(5) = 60 + 15 = 75°(9y - 7)° = 9(5) - 7 = 45 - 7 = 38°(6x - 5)° = 6(12) - 7 = 72 - 7 = 67°

⇒ Their angles are equal (in ΔLMN and ΔSTU)

⇒ ΔLMN and ΔSTU are similar
