Answer:

The area of the triangle is of 6 units squared.

Step-by-step explanation:

Representation of the triangle:

This triangle, in the cartesian plane, has the vertices at these following points.

(7,7)

| -> 4 units down

(7,3) --- (10,3) -> 3 units to the right.

This can be represented as a right triangle with sides 4 and 3.

Area of a right triangle:

The area of a right triangle is the multiplication of the lengths of its sides divided by 2. So

4*3/2 = 12/2 = 6.

The area of the triangle is of 6 units squared.

The line plot shows the growth, In Inches, of Isabella's plant over 13 days. Growth of Isabella's Plant What is the total growth

mart [117]

Line plots are used to display data elements using markers

The total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches

<h3>How to determine the total growth</h3>

From the line plot, the total growth can be represented as:

$Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3$

Evaluate the products

$Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8$

Evaluate the sum

$Total = \frac{4+4+9+4+15}8$

Evaluate the numerator

$Total = \frac{36}8$

Evaluate the quotient

$Total = 4\frac{1}2$

Hence, the total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches

Please answer a through d

Elza [17]

Answer:

See explanation below.

Step-by-step explanation:

Given: 100 lbs on Earth is 16.6 lbs on the moon.

a. The independent variable is weight. The gravity of the Moon and the gravity of the Earth are constant. Weight can change, but gravity is a constant.

b. An equation that relates the weight of someone on the Moon who travels to the Earth:

100 / 16.6 = 6.02. Take the Moon weight and multiply by 6.02:

Moon Weight * 6.02 = Earth Weight.

Proof:

16.6 * 6.024 = 99.99 - approximately 100 lbs Earth weight.

c. A 185 lb astronaut on Earth would weigh:

16.6 / 100 = .166. Take the Earth weight and multiply by .166:

185 * .166 = 30 lbs on the Moon.

d. A person who weighs 50 lbs on the Moon:

50 * 6.024 = 301.2 lbs on Earth.

Hope this helps! Have a good day and year! :)
