Answer:
B
Step-by-step explanation:
Initial mean = 156, Changed mean = 163.92
So, mean increases. Only condition that satisfies this is B.
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
15 js the base of the rectangle because you find the area by doing length times width
Answer:
x to the third power is x cubed or x^3.
It is 3 because if you count it 5-11 that’s 6 but you have to divide it by 2 sense there is 2 so that answer is 4
