i think it’s 34.075

Answer:

34.075       For some reason it wouldn't let me answer so I typed it in the comment section. I didn't copy anyone elses answer tho!!

Step-by-step explanation:

I use the flag method, take 40x34 that gives you 1,360. then you take that and add 3 so, 1,363. then you take that back over the 40 so 1,363/40. you divide those bc thats what the line means. so then you get, 34.075

Answers

Answer:

97 8/10

Explanation:

If you weighed 97.8 pounds on saturn as a decimal, you would take the whole number 97. Now you're left with the ".8" = ".80" this decimal would be 8/10. Now you put them together to create 97 and 8/10.

Answers

Answer:

5.4

Step-by-step explanation:

the answer is 5.4

Explanation:
3 is 3/4 of 4. this means the figure on top is 3/4 the size of the figure on the bottom. so x = 3/4(7.2)
3/4 is equal to .75, so if you multiply 7.2 by .75 (multiplying it by 3/4), you get the measure of x. in this case, x = 5.4

Answer:

  x = 27°

Step-by-step explanation:

Each exterior angle is equal to the  sum of the remote interior angles.

  6x = 90° +(180° -4x)

  10x = 270° . . . . . add 4x

  x = 27° . . . . . . . . divide by 10

_____

Check

6x = 162°, so the adjacent interior angle of the triangle is 180° -162° = 18°.

4x = 108°, so the adjacent interior angle of the triangle is 180° -108° = 72°.

The interior angles of the triangle are complementary, as they should be.

  18° +72° = 90°

If f(x)= x^2-6x-14 find the value of f(-2) (I prefer some kind of help rather than an answer, but answers are welcome)

Answers

Step-by-step explanation:

In order to figure out what is f(-2), we substitute all the "x" in the function with "-2" like this:

f(-2) = x² - 6x - 14 = (-2)² - 6(-2) -14

Now we can follow PEMDAS:

(-2)² - 6(-2) -14

= 4 + 12 - 14

= 2.

Hence, f(-2) = 2.

Plug -2 in for x throughout the equation. f(x) = -2^2 - 6(-2) - 14. Then solve.
