Answer:

8 units ^2

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh where b is the length of the base and h is the height

b = LK = 4 units

h = J to where LK would be extended to, which would be 4 units

A = 1/2 (4) * 4

A = 8 units ^2

Norm must pay to have trash collected he can put out 1 barrel of trash per week a rectangler container measure 32 inches by 18 i

Ainat [17]

Answer:

The Cycling Rick container can hold more trash.

Step-by-step explanation:

The rectangular container is basically a rectangular prism, so to find its volume, we are using the formula for the volume of a rectangular prism:

$V=whl$

where

$V$ is the volume

$w$ is the width

$h$ is the height

$l$ is the length

We know that the rectangular container is 32 inches by 18 inches by 10 inches, so $l=32in$ , $w=18in$ , and $h=10in$ . Let's replace the values in our formula:

$V=whl$

$V=(18in)(10in)(32in)$

$V=5760in^3$

The rectangular container can hold 5760 cubic inches of trash.

Now, the Cycling Rick container is basically a cylinder, so to find its volume, we are suing the formula for the volume of a cylinder:

$V=\pi r^2h$

where

$V$ is the volume

$r$ is the radius

$h$ is the height

We know that the its height is 30 inches, so $h=30in$ . Since the container is 20 inches wide, its diameter is 20 inches, and since the radius is half the diameter, $r=\frac{20in}{2} =10in$ . Let's replace the values:

$V=\pi r^2h$

$V=\pi (10in)^2(30in)$

$V=9424.78in^3$

The Cycling Rick container can hold 9424.78 cubic inches of trash.

Since 9424.78 cubic inches is bigger than 5760 cubic inches, we can conclude that the Cycling Rick container can hold more trash.

In this triangle, the product of sin Band tan cis and the product of sin cand tan is

Alborosie

Answer:

In this triangle, the product of sin B and tan C is c/a or cos B, and the product of sin C and tan B is b/a cos C. We determine these as follows:

sin B tan C = b/a (c/b) = c/a

sin C tan B = c/a (b/c) = b/a

Hope this answers the question. Have a nice day.

A company manufactures aluminum mailboxes in the shape of a box with a half-cylinder top. The company will make 1823 mailboxes t

Rudik [331]

Answer:

$\large \boxed{\text{2145 m}^{2}}$

Step-by-step explanation:

The area of one mailbox = the area of a rectangular box - the top of the box plus half the area of a cylinder.

SA = SA(box) - SA(top) + ½SA(cylinder)

1. Surface area of box

The formula for the surface area of a rectangular box is

SA = 2(lw + lh + wh)

Data:

l = 0.55 m

w = 0.3 m

h = 0.4 m

Calculations:

2(Top + Bottom = 2lw = 2 × 0.55 × 0.3 = 0.33 m²

2(Left + Right) = 2wh = 2 × 0.55 × 0.4 = 0.44 m²

2(Front + Back) = 2lh = 2 × 0.3 × 0.4 = 0.24 m²

Total area = 1.01 m²

2. Surface area of cylinder

The formula for the surface area of a cylinder is

SA = A(top) + A (base) + A(side) = 2A(base) + A(side)

Data:

d = 0.3 m

h = 0.55 m

Calculations:

r = ½d = ½ × 0.3 = 0.15 m

$\begin{array}{rcl}SA & = & 2\pi r^{2}+ 2\pi rh \\& = & 2 \times 3. 14\times 0.15^{2} +2\times 3. 14 \times 0.15\times 0.55\\& = & 6.28\times 0.0225 + 0.5181\\& = & 0.1413 + 0.5181\\& = & \mathbf{0.6594} \textbf{ m}^{\mathbf{2}}\\\end{array}$

3. Excluded area

1 top = ½ × 0.33 m² = 0.165 m²

½ cylinder = ½ × 0.6594 m² = 0.3297 m²

Total excluded = 0.4947 m²

4. Surface area of 1 mailbox

SA = (1.01 + 0.6594 - 0.4927) m² = 1.1767 m²

5. Total area of 1823 mailboxes

$\text{Total area } = \text{1823 mailboxes} \times \dfrac{\text{1.1767 m}^{2}}{\text{1 mailbox}} = \textbf{2145 m}^{\mathbf{2}}\\\\\text{The company will have to use $\large \boxed{\textbf{2145 m}^{\mathbf{2}}}$ of aluminium.}$
