Answer:
95 square units
Step-by-step explanation:
Surface area of pyramid = 4(side area) + base
Solve for the base first.
Area of base = s*s = 5*5 = 25
Next solve for one of the sides.
Area of triangle = 1/2 b*h = 1/2 5*7 = 17.5
Plug these back into our original equation.
Surface area of pyramid = 4(side area) + base
Surface area of pyramid = 4(17.5) + 25
Surface area of pyramid = 70 + 25 = 95 square units
Answer:
1) 2b + 6
2) 8w - 12
3) 2b + 6 + 6x + 20
4) 9w^2 + 27 + 8 - 27
5) Sorry.
Step-by-step explanation:
32. 15.99 x .40 = 6.40
15.99 - 6.40 = 9.59
80/ 9.59 = 8.34
Jenny can buy A. 8 CD’s with her $80
31. 5,000 x .10 = 500
5,000 - 500 = 4,500
4,500 x .15 = 675
4,500 + 675 = 5,175
Ben will earn C. $5,175 after one year one the job
The answer is B.
In the question it says "the intercept of 6" which means the equation has to have +6 in the answer, and there is only one answer choice containing that.
Answer: 16 inches
Step-by-step explanation:
The area of a triangle = bh/2
where b = base = unknown
h = height = 5 3/4 inches
Area = 46 inches²
Therefore, 46 = base × 5 3/4 / 2
Cross multiply
46 × 2 = base × 5 3/4
92 = base × 5 3/4
Base = 92 ÷ 5 3/4
Base = 92 ÷ 23/4
Base = 92 × 4/23
Base = 4 × 4
Base = 16 inches
