9. 12 edges

Work: 4 horizontal edges on top, 4 horizontal edges on bottom, 4 vertical edges for sides

10. Ten-thousands place

Work: The 8 is highlighted. The order of places is: ten-thousands, thousands, hundreds, tens, ones

11. 10 4/5

Work: 54 ÷ 5 ——> 50÷5 = 10 with 4 left over and put into a fraction of 4/5

12. 3,000

Work: 2 is in the thousands place so you look to the place behind it and there is an 8. If the number behind is 5 through 9 then you round up. 8 is above 5, therefore, you round the 2 up to a 3.

13. 0.45

Work: The pattern is +0.03 so 0.42+0.03=0.45

14. 54 cakes

Work: 6 eggs per 1 cake • 9 cakes = 6•9=54 eggs used

15. 378 desks in the school

Work: 6 rows • 7 desks per row = 42 desks in 1 classroom. 42 desks • 9 classrooms = 378 desks in the whole school

small cubes with edge lengths of 1/4 inch will be packed into the right rectangular prism shown.( the base is 4 1/2, the width i

ss7ja [257]

General Idea:

We need to find the volume of the small cube given the side length of the small cube as 1/4 inch.

Also we need to find the volume of the right rectangular prism with the given dimension (the height is 4 1/2, the width is 5, and the length is 3 3/4).

To find the number of small cubes that are needed to completely fill the right rectangular prism, we need to divide volume of right rectangular prism by volume of each small cube.

Formula Used:

$Volume \; of \; Cube = a^3 \; \\\{where \; a \; is \; side \; length \; of \; cube\}\\\\Volume \; of \; Right \; Rectangular \; Prism=L \times W \times H\\\{Where \; L \; is \; Length, \; W \; is \; Width, \;and \; H \; is \; Height\}$

Applying the concept:

Volume of Small Cube:

$V_{cube}= (\frac{1}{4} )^3= \frac{1}{64} \; in^3\\\\V_{Prism}= 3 \frac{3}{4} \times 5 \times 4 \frac{1}{2} = \frac{15}{4} \times \frac{5}{1} \times \frac{9}{2} = \frac{675}{8} \\\\Number \; of \; small \; cubes= \frac{V_{Prism}}{V_{Cube}} = \frac{675}{8} \div \frac{1}{64} \\\\Flip \; the \; second \; fraction\; and \; multiply \; with \; the \; first \; fraction\\\\Number \; of \; small \; cubes \;= \frac{675}{8} \times \frac{64}{1} = 5400$

Conclusion:

The number of small cubes with side length as 1/4 inches that are needed to completely fill the right rectangular prism whose height is 4 1/2 inches, width is 5 inches, and length is 3 3/4 inches is 5400

Does doubling the radius of a sphere double the surface area? Explain your reasoning using an example.

Annette [7]

Answer:

yes

Step-by-step explanation:

because area of sphere equals =

$4\pi \: r{2}$

so if we doubled the radius the surface area will be doubled
