To round to a whole number look at the 1st digit after the decimal if it’s 4 or less you round down but if it’s 5 or more you round up a number. In this case u would round down and your answer would be 523

What is the surface area of the square pyramid, in square inches (Please Help)
ad-work [718]

Answer:

220.8 in.²

Step-by-step explanation:

Area of the pyramid = area of the square + 4(area of the triangle)

Area of square = s²

s = 9.2 in.

Area of the square = 9.2² = 84.64 cm²

✔️Area of the 4 triangles = 4(½*bh)

b = 9.2 in.

h = 7.4 in.

Area = 4(½*9.2*7.4) = 136.16 in²

✅Surface area = 84.64 + 136.16 = 220.8 in.²

What are all the rational roots of the polynomial f(x) = 20x4 + x3 + 8x2 + x – 12?
Eduardwww [97]

Answer:

-0.8 and 0.75.

Step-by-step explanation:

20x^4 + x^3 + 8x^2 + x – 12 = 0

by the rational roots theorem:-

The leading coefficient is 20 with factors +/-  1,2,4,5,10,20

and the constant is -12 with factors  +/- 1,2,3,4,6,12

so there are many possible roots like -1, 2, 3/4 3/5 , -4/5 .....

Drawing a graph would be the quickest way to do this,  either manually, using graphical software or a graphical calculator.

I used the latter and got 2 rational roots -0.8 and 0.75.

Cindy spent $15.25 on ingredients for a blueberry pie and $12.84 on ingredients for a cherry pie. Each slice of pie sells for $3
Brums [2.3K]

Answer:

61.07 dollars profit

Step-by-step explanation:

15.25 for blueberry pie =  24 slices (8 slices in a pie)

12.84 for cherry pie =  15 slices (8 slices in a pie)

24x3.50=84

15x3.50=52.5

2x12.84=25.68

3x15.25=45.75

84-45.75=34.25

52.5-25.68=26.82
