There's a lot of trees, so wood.
Answer:
Cube surface Area = edge^2 * 6 therefore,
edge^2 = surface area / 6
edge^2 = 294 / 6
edge^2 = 49
edge (or side) = 7 inches
Step-by-step explanation:
Answer:
The value of y is 3.
Step-by-step explanation:
Given points: P(12,-2), Q(5,-10), R(-4,10) and S(4,y).
We need to find the value of y so that line PQ is perpendicular to line RS.
Slope formula:
Slope of PQ is
Slope of RS is
The product of slopes of two perpendicular lines is -1.
Add 10 on both sides.
Therefore, the value of y is 3.
You can always treat such examples as an equation;
(90+96+86+92+X)/5=90
X is the desired score, 5 is the number of tests. As you can see, it is the usual equation for getting the mean value which the sum of the values over their number.
now; 90+96+86+92+X=90*5
X=90*5-(90+96+86+92)
X=86.
Hope this helps.
