Answer:

width is = 26ft

length is = 31ft

Step-by-step explanation:

The area of hall is 806 sq. ft.

length is 5 ft greater than its width.

L = 5+b

L*b = 806

(5+b)*b= 806

5b +b² = 806

B²+5B-806= 0

Solving quadratically

B² +31B -26B -806= 0

B(B+31)-26(B+31)= 0

(B-26)(B+31)= 0

B= 26 or -31

So the value of the width must be positive so the width is = 26ft

If width is 26, length is 26+5 = 31ft

A 4-L water filter is used to fill 200 mL cups and three 750 mL drink bottles How much water is left in the water filter
Ierofanga [76]

Answer:

1550 mL

Step-by-step explanation:

Total capacity of water = 4 Litre

4 L = 4 * 1000 mL = 4000 mL

200mL cups filled = 1 ; 200 mL

750mL cups filled = 3 ; 750 * 3 = 2250 mL

Total = (200 + 2250) mL = 2450 mL

Water left in filter :

(4000 - 2450) mL = 1550 mL

What is the solution to the equation 3.6m − 2.7 = −1.8m?
Finger [1]

Answer:

Option B is correct

m = 0.5 is the solution to the equation

Step-by-step explanation:

Given the equation:

3.6m-2.7= -1.8m

Add 2.7 to both sides, we have;

3.6m-2.7+2.7= -1.8m+2.7

Simplify:

3.6m = -1.8m+2.7

Add 1.8 m to both sides we have;

5.4m =2.7

Divide both sides by 5.4 we have;

m = \frac{1}{2} = 0.5

⇒m = 0.5

Therefore, the solution for the given equation is, 0.5
