answer:
The answer is 9 to all the question
Step-by-step explanation:
The question only wants to add the digits that you have find the product,
9.7=63.
so the question wants you to add the digit of the product 9.6 which is 63 so you will do this;
6+3=9
This good question needs a good answer which is......854.96
The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,
A = bh / 2
where A is area, b is base and h is the height.
Substituting the known values,
A = (4 inch)(9 inch) / 2 = 18 in²
Multiplying this area by 4 will give us an answer of 72 in².
Then, we also calculate for the area of the square base.
A = s²
where s is the measure of each side of the square.
A = (4 in)² = 16 in²
Finally, we add up the calculated areas.
surface area = 72 in² + 16 in²
<em>surface area = 88 in²</em>
Hence, the surface area of the figure is equal to 88 in².
Answer: x = 7, y = -3
Step-by-step explanation:
2x - y = 17
x - y = 10 —> x = y + 10
2(y + 10) - y = 17
2y + 20 - y = 17
y + 20 = 17
-20 -20
y = -3
x = y + 10
x = (-3) + 10
x = 7
This is an example of how you solve an inequality.
