Wangari plants trees at a constant rate of 1212 trees every 33 hours. Write an equation that relates pp, the number of trees Wan

igor_vitrenko [27]

Answer:

$p=4h$

Step-by-step explanation:

Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.

We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.

Let us find number of trees planted in 1 hour by dividing 12 by 3.

$\text{Number of trees planted in 1 hour}=\frac{12\text{ plants}}{3\text{ hour}}$

$\text{Number of trees planted in 1 hour}=4\frac{\text{ plants}}{\text{ hour}}$

We can represent this information as: $p=4h$

Therefore, the equation $p=4h$ relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.

Write two division expression s that have the same vaule as 36.8 ÷ 2.3

Triss [41]

<h3>Write two division expression s that have the same vaule as 36.8 ÷ 2.3 </h3>

$32 \div 2 = 16\\\\48 \div 3 = 16$

Solution:

Given that,

We hve to find the two division expression s that have the same vaule as 36.8 ÷ 2.3

From given,

$36.8 \div 2.3 = 16$

So, we have to find two division expressions that has a value of 16

First division expression

We know that 32 divided by 2 gives 16

Thus, we can write as,

$32 \div 2 = 16$

Second Expression:

We know that 48 divided by 3 gives 16

Thus, we can write as,

$48 \div 3 = 16$

Thus the two expressions are found

Find the volume V of the described solid S. The base of S is the triangular region with vertices (0, 0), (3, 0), and (0, 3). Cro

Reil [10]

Answer:

27/2

Step-by-step explanation:

Given

Vertices (0, 0), (3, 0), and (0, 3)

Since the base of the equilateral in the plane perpendicular to the x-axis goes from the x-axis to the line y = 3 - x.

So, the length of each side of the triangle is (3-x)

Calculating the area;

Area = ½bh

Where b = base = 3 - x

height is calculated as;

h² = (3-x)² + (½(3-x))² --- from Pythagoras

h² = 9 - 6x + x² + (3/2 - ½x)²

Let h² = 0

0 = 9 - 6x + x² + (9/4 - 6/4x + ¼x²)

0 = 9 + 9/4 - 6x - 6/4 + x² + ¼x²

0 = 45/4 - 30x/4 + 5x²/4

0. = 5x²/4 - 30x/4 + 45/4

0 = 5x² - 15x/4 - 15x/4 + 45/4

0 = 5x(x/4-¾) - 15(x/4 - ¾)

0 = (5x - 15)(x/4 - ¾)

5x = 15 or x/4 = 3/4

x = 3 or x = 3

So, h = 3

Area = ½bh

Area = ½ * (3-x) * 3

Area = ½(9-3x)

Volume= Integral of ½(9-3x) {3,0}

V = 9/2 - 3x/2 {3,0}

V = 9x/2 - 3x²/4 {3,0}

V = 9(3)/2 - 3(3)²/4

V = 27/2 - 27/4

V = 27/2
