Answer:
measure of other diagonal is 30cm
Step-by-step explanation:
let the other diagonal be d .
- area of rhombus = 1/2 × 16 × d
- 240 = 8 × d
- d = 240 / 8
- d = 30
hence the other diagonal = d = 30 cm
Answer:
-2.8
Step-by-step explanation:
1.4(2-4)
1.4(-2)
=-2.8
Answer:
-$1.9
Step-by-step explanation:
There are 47 pages.
Printing on both sides would divide the number of pages into half.
47/2 = 23.5
2 pages on each side would mean 4 pages on one sheet. Therefore, the number of pages will be further divided by 2.
23.5/2 = 11.75
There cannot be 11.75 pages so we will round it up to 12 pages.
Each page costs $0.25 so 12 pages will cost:
12 x 0.25 = $3
Faithi has $1.1 so new account balance will be:
1.1 - 3 = $-1.9
Therefore, Fathi's balance in his printing account would be negative $1.9.
