It’s A
1213 divided by 9 is equal to 134.777778
So it is 134 R7
But if it’s rounded to the nearest then it is C.
Answer:
- 8
Step-by-step explanation:
Evaluate f(1) and f(- 1) by substituting x = 1 and x = - 1 into f(x)
Given
f(x) = x² - 4x + 6, then
f(1) = 1² - 4(1) + 6 = 1 - 4 + 6 = 3
f(- 1) = (- 1)² - 4(- 1) + 6 = 1 + 4 + 6 = 11
Thus
f(1) - f(- 1) = 3 - 11 = - 8
Step-by-step explanation:
5.
angle STQ is the supplementary angle (together they are 180° below line MQ) to 2x + 8.
above ST we have a group of 3 angles that combine to 180° :
2x + 8
90°
71 - x
so, to get x first :
2x + 8 + 90 + 71 - x = 180
x + 169 = 180
x = 11
so, the angle MTS =
2x + 8 = 2×11 + 8 = 22 + 8 = 30°.
6.
therefore, the angle STQ is
180 - angle MTS = 180 - 30 = 150°.
It would be 55.97
To find this you find what 20% of 69.96 is and subtract that number from 69.96 (in this case that number would be 13.99) So you would find your answer of 55.97
Answer:
It was an increase of 200%.
Step-by-step explanation:
In order to identfy the percent of the change we need to first find the absolute value, to do that we subtract the final value from the initial one. We have:
absolute difference = 36 - 12 = 24 inches
Since this value is positive it was an increase. Now we need to find the percentage at which it was increased, to do that we can use a rule of three in a way that the original value is 100% and the value we want to know is the percentage for the absolute increase. We do this as follows:
12 inches -> 100%
24 inches -> x %
12*x = 2400
x = 2400/12 = 200 %
It was an increase of 200%.
