111
rodikova [14]

Since 111, 777, and 999 are all bigger than 20, make them smaller. Take out one 1, two 7, and two 9  (5 numbers):  11 + 7 + 9 ≠ 20 (it equals 27). Now take out number 7.  (If you take out number 1 [1+7+9=17, not 20] and of you take out number 9 [11+7=18, not 20].

11 + 9 = 20  (you took out numbers: 1, 7, 7, 7, 9 and 9 [6 numbers]).

Find the amount of cardboard needed to make a box for a single slice of pizza. The box is shoen in the shape of a triangular pri
Molodets [167]
For this case, what you should do is calculate the surface area of the figure.
 We have then:
 Triangles:
 A1 = (1/2) * (7) * (12)
 A1 = 42 in ^ 2
 Rectangles:
 A2 = (1) * (12.5)
 A2 = 12.5 in ^ 2
 A3 = (1) * (7)
 A3 = 7 in ^ 2
 Finally, the total surface area is:
 A = 2A1 + 2A2 + A3
 Substituting values:
 A = 2 (42) + 2 (12.5) + (7)
 A = 84 + 25 + 7
 A = 116 in ^ 2
 Answer:
 
the amount of cardboard needed to make a box for a single slice of pizza is:
 
A = 116 in ^ 2

Grayson can text 70 words in 4 minutes. At this rate, how many minutes would it take
yuradex [85]

The minutes taken by Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.

<h3>What is division?</h3>

It is the basic arithmetic operation, in which you are separating the number into some parts.

Given:

Grayson can text 70 words in 4 minutes,

The time is taken to type one word = 4 / 70 = 0.057 min

Thus, typing 140 words Grayson would take  = 0.057 × 140 = 8 min

Therefore, the minutes taken Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.
