Surface area = 56 cm2
Explanation:
Area of square base = Side x Side = 4 x 4 = 16 cm2
Area of triangle = 1/2 x Base x Height = 1/2 x 4 x 5 = 10 cm2
Area of 4 triangles = 10 x 4 = 40 cm2
Surface area of pyramid = 16 + 40 = 56 cm2
The answer to this question is 5. after you replace x and simply you get 5 as your answer. hope this helps
X-intercept means y equals to 0
y-intercept means x equals to 0
If you plug in (0, 1) and (1, 0), you will notice that only x + y = 1 will work for both points
Your answer is B) x + y = 1
Add the prices of the food together to get $7. Then you calculate the sales tax, which is 1.04 * $7 = $7.28. The tip is 15% I am assuming, and not 15, so it would be $7 * 0.15 = $1.05. Add $1.05 with $7.28 to get $8.33, so the answer is A.
