(a) If 200 calories are burned in 10 minutes...then what about 1 calorie

; 1/200 × 10 = 0.05 minutes

(b) Slope of the graph...;just take any two points on the graph...which are (10;200) and (20;400)

Slope = (400 - 200) ÷ (20 - 10)

;Slope = 200 ÷ 10

Answer:

L= 0.83 in

Step-by-step explanation:

Width= 1.2 in when length = 1 in

Required

Determine the length when width = 1 in

First, we need to determine the ratio

Ratio = $\frac{Width}{Length}$

Ratio = $\frac{1.2}{1}$

Ratio = 1.2 ---(1)

Let the required length be represented with L

So:

Ratio = $\frac{Width}{Length}$

Ratio = $\frac{1}{L}$ ---(2)

Equate (1) and (2)

$\frac{1}{L}$ = 1.2

Multiply through by 1.2

L * $\frac{1}{L}$ = 1.2 * L

1 = 1.2 * L

Divide through by 1.2

L = $\frac{1}{1.2}$

L = 0.83 in (Approximated)

A rectangle container that has a length of 30 cm,a width of 20 cm,and a height of 24 cm is filled with water to a depth of 15 cm

Ket [755]

V(h 24) = 30 cm*20 cm*24 cm = 14400 cm³ = 14,4 liters
V(h 15) = 30 cm*20 cm*15 cm = 9000 cm³ = 9 liters
 + 6,5 liters = + 6500 cm³ 
9 liters + 6,5 liters = 15,5 liters => 15,5 liters -14,4 liters = 1,1 liters
now 15500 cm³ => 1100 cm³ =1,1 liters too much !!
Answer: 1,1 liters of water overflow the container.
