7 0

5.8 × 10⁻¹ = 0.58

7.4 × 10⁰ = 7.4

0.58 - 7.4 = -6.82

(5.8 × 10⁻¹) - (7.4 × 10⁰) = -6.82 × 10⁰

mr_godi [17]

Answer:

12 days

Step-by-step explanation:

Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults

3 $\frac{1}{2}$ + 1 $\frac{3}{4}$ =

Converting to decimals

3.5 + 1.75 = 5.25 = 5 $\frac{1}{4}$

If there are 63 gallons, the water supply would last for :

63 / 5.25 =12 days

Please help me on this

IrinaVladis [17]

Answer:

Step-by-step explanation:

coordinate of O(2,1),Y(3,-2),T(-3,-3)

let the reflected points are O',Y',T'

distance of O from y=2 is 1 unit.

∴ ordinate of O' =1+2(1)=3

or O' is (2,3)

distance of Y from y=2 is2+2=4

ordinate of Y'=-2+2(4)=6

so coordinate of Y' is (3,6)

distance of T from y=2 is (2+3)=5

so ordinate of T' =-3+2(5)=7

coordinate of T' is(-3,7)

Determine how many crayfish may be stocked at 20 crayfish/sq meter in a 1000 gallon circular tank of 3 ft deep and 6 ft in diame

levacccp [35]

Answer:

Total stocked of crayfish is = 315.2

Step-by-step explanation:

Given data:

stocked of crayfish $= 20 crayfish/m^2$ in 1000 gallon water tank

size of tank = 3 ft deep and 6 feet diameter

let radius of tank is r and height of tank is h m

Total stocked of crayfish is $=20\times area\ of\ cylinder$

$= 20[ 2\pi r(r+h) ft^2]$

$=20\times 2\pi \times3 (3+6) \times 0.3048$ [1 ft = 0.3048 m]

= 315.2
