Answer:
Last equation 350 - 170 - 120 = r
Step-by-step explanation:
So if she ordered 350, and we already know 170 + 120 for black and blue pens. So we add 170 and 120 to get 290. So we subtract 290 from 250 and get 60. So the equation is 350 - 170 - 120 = r. Brainliest please!
Answer:
4. °
Step-by-step explanation:
Given:
The tangent of the angle is given as:
Since the angle is negative, it means that it is measured in the clockwise direction as angles measured in clockwise direction are negative and that measured in counter clockwise directions are positive.
-212° when measured from counter clockwise direction will be equal to:
Therefore, =
Now, we have the identity for tan as:
Here,
Therefore,
Hence, = = °
Answer:
Its 7
Step-by-step explanation:
when x is 18 y is 6. 18 divided by 6 is 3.
so x is 21 divided by 3 is 7.
Answer:
Do you mean:
(1+(2/3))j = 15
((3/3)+(2/3))j = 15
((3+2)/3)j = 15
(5/3)j = 15
j = 15 / (5/3)
j = 15 * (3/5)
j = 9
Step-by-step explanation:
You basically have to take it to the power of half.
example to find the square root of 4,
take 4^0.5 = 2
hope this helped
