Answer:

The unit rate in ml per kg is 1.75 ml per kg.

Step-by-step explanation:

The amount of medicine, in milliliters, that a veterinarian prescribes is proportional to the weight, in kilograms, of a dog as shown on the graph.

In the graph x-axis labeled weight in kg and y-axis labeled the amount of medicine in ml. The points (0,0) and (8,14) are on the graph.

Hence, the slope of the graph represents the unit rate in ml per kg.

Now, the slope of a straight line passing through the points ( $x_{1},y_{1}$ ) and ( $x_{2},y_{2}$ ) is given by $[\frac{y_{2} - y_{1}}{x_{2} - x_{1}}]$ .

Therefore, the slope of the graph will be $\frac{14 - 0}{8 - 0} = \frac{7}{4} = 1.75$ and the unit rate in ml per kg is 1.75 ml per kg. (Answer)

kogti [31]

Answer:

Day 21: 810 m

Day 60: 1,200 m

Step-by-step explanation:

The amount of meters she walk everyday can be modeled as a linear function, as the rate of variation is a constant (10 m/day):

$dD/dt=10\;\text{m/day}$

This constant (10 m/day) is the slope of the linear function.

We know one point of the linear function (D(20)=800) and the slope, so we can calculate the y-intercept:

$D(t)=10t+b\\\\D(20)=10*20+b=800\\\\b=800-10*20=800-200\\\\b=600$

Now, we can calculate the distance she walks by day 21 and day 60:

$D(21)=10*21+600=210+600=810\\\\\\D(60)=10*60+600=600+600=1,200$

A gardener makes a new circular flower bed. The bed is teen feet in diameter. Calculate the circumference and the area of the ci

KATRIN_1 [288]

Answer:

I. Circumference of circular flower bed = 31.42 ft.

II. Area of circular flower bed = 78.55 ft²

Step-by-step explanation:

Given the following data;

Diameter = 10 ft

Radius = diameter/2

Radius = 10/2

Radius, r = 5 ft

I. To find the circumference of the circular flower bed;

Circumference of circle = 2πr

Substituting into the formula, we have

Circumference of circular flower bed = 2*3.142*5

Circumference of circular flower bed = 31.42 ft

II. To find the area;

Area of circle = πr²

Substituting into the formula, we have;

Area of circular flower bed = 3.142*5²

Area of circular flower bed = 3.142*25

Area of circular flower bed = 78.55 ft²

8. A pyramid has a volume of 8 cubic feet. The height is 2 feet. The base is rectangular. Give possible dimensions for the lengt

jeka57 [31]

Answer:

base = 12 ft²

The base could be 3 ft x 4 ft, 6 ft x 2 ft, etc. (any numbers multiplied together = 12)

Step-by-step explanation:

volume = 1/3bh

8 = 1/3b(2)

multiply both sides of the equation by 3:

24 = 2b

b = 12 ft²
