Answer:
22
Step-by-step explanation:
Boys to Girls
5 to 6
10 to ?
Since 10 is twice as much as 5, we have to multiply the number of girls by 2. 6 times 2 is equal to 12. Then, since we need to find the total number of boys and girls, we have to add both sides. 10 (boys) plus 12 (girls) equals 22.
first, add 14+8 and get 22 then do 22* 40 and get 880 so $880
Answer:
40.5 square inches
Step-by-step explanation:
Rectangle consists of two identical squares.
So, if the sides of square = x,
Then, Width of rectangle = x &
Length of rectangle = x +x = 2x
Perimeter of rectangle = 27 inches
2*(length + width) = 27
2*( 2x + x) = 27 {Combine like terms]
2* 3x = 27
6x= 27 {Divide both sides by 6}
x = 27/6
x = 4.5
Width = x = 4.5 inches
Length = 2x = 2*4.5 = 9 inches
Area of rectangle = length *width
= 4.5 *9
= 40.5 square inches
17) 3*5 + 4 = 19
18) 2 * 3 = 6
19) 3 * 36 + 2 * 6 + 1 = 121
20) 5 * 49 + 6 * 7 = 287
21) 6 * 64 + 6 * 8 + 6 = 438
22) 1 * 81 = 81
23) 1 * 8 + 1 * 4 = 12
24) 7 * 729 + 5 = 5108
25) 1 * 1296 + 5 * 216 + 2 * 36 = 2448
26) 1 * 16 + 1 * 2 = 18
27) 4 * 3125 + 1 * 25 + 2 * 5 + 3 = 12538
