The surface area is 54 square inches
Answer:
90 sq inches
Step-by-step explanation:
The lateral area is the side area of the pyramid. In this case, there are 3 sides because the base is a triangle. Since the base is an equilateral triangle, all sides are of equal dimensions. So, the sides of the pyramid are also all of the same size, area.
We then just have to figure out the area of one of the side triangles, then multiply it by 3 to get the total lateral area of that pyramid.
We know how to calculate the area of a triangle: A = (b * h)/2
In this case, b = 5 in, h = 12 in. So,
TA = (5 * 12)/2 = 60 / 2 = 30
Each side triangle has an area of 30 sq inches.
LA = 3 * TA (since there are 3 sides)
LA = 3 * 30 = 90 sq inches
Answer:
The answer is A.
Step-by-step explanation:
Given that Winnona took 5 tests and retake Test 5. So the mean score for this question is Total number of scores divide by Total number of tests is equals to 87 :
Let Test 5's score be x,
Let mean score be 87,
Next you have to solve the value of x :

Step-by-step explanation:
1. $10.20/6 = 1.7 = the amount Michael receives for 1 pound of blueberries
2. We know that for 12 pounds he will receive $20.40 and if we do 1.7*4 for the remaining four pounds then do $20.40 + (1.7*4) = $27.20, D
