Answer:
1 3/4=7/4 since 1*4+3=7, so (90/7)/(7/4)=(90/7)(4/7)=360/49, mixed number form is 7 17/49 and in decimal form is 7.35.
Step-by-step explanation:
1) would be 2 boxes because the room is 25 ft²
2) $99.50 if you do 25 x 3.98, or if they want 40 x 3.98 it would be $159.20
10 * 10^2 - 7.79* 10^3
they have to be to the same power to add or subtract
change 10*10^2 to proper scientific notation (only 1 number before the decimal) 1*10^3
1*10^3 - 7.79*10^3 = (1-7.79) * 10^3=-6.79*10^3
When exactly one of the integers is negative.
For example, -24*(36)=-864 which is smaller than any of the factors of the integers.
