Answer:

To find the surface area of a cuboid, add the areas of all 6 faces. You can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:

Surface Area: 204mm^2

Step-by-step explanation:

The formula for the surface area of a rectangular prism is: 2(lw + wh +lh)

Our length, width and height are:

Length: 15mm

Width: 3mm

Height: 4mm

Then, we plug it in.

2(15x3 + 3x4 + 15x4)

2(30 + 12 + 60)

2(102)

204mm^2

Therefore, our surface area for the rectangular prism is 204mm^2.

Graph the solution to the following linear inequality in the coordinate plane. 5 x - y > -3
Svetlanka [38]

Given:

The inequality is:

5x-y>-3

To find:

The graph for the given linear inequality in the coordinate plane.

Solution:

We have,

5x-y>-3

The related equation for this inequality is:

5x-y=-3

The table of values is:

x         y

0        3

-1        -2

Plot the points (0,3) and (-1,-2) on a coordinate plane and connect them by a dotted straight line because the sign of inequality is >.

Check the given inequality for (0,0).

5(0)-(0)>-3

0>-3

This statement is true. So, the shaded area of the given inequality is towards the origin.

Therefore, the required graph is shown below.

The diagram below shows a student using a clinometer to measure the height of a flagpole. When the student stands 40 feet away f
AVprozaik [17]
The correct answer is the flagpole is <span>33 feet high</span>.

Explanation:
Please refer to the attached picture.

We know:
CD = 40 feet
AC = 5 feet
∠BDC = α = 35°

Using trigonometry, we know that the definition of the tangent of an angle is the ratio between the opposite side and the adjacent side, therefore:
tan α = BC / CD

Solving for BC:
BC = CD · <span>tan α
      = 40 </span>· tan (35)
      = 28 feet

In order to find the height of the flagpole, we need to add the distance of the clinometer from the ground:
AB = BC + AC
      = 28 + 5
      = 33

Hence, the flagpole is 33 feet high.

What is it AHHH HELP‼️
TEA [102]

Answer

5.5cm

Step-by-step explanation:

The radius of a circle is the distance from the center of the circle to any point on its circumference.

The easiest way to find the radius is by dividing the diameter in half.

Radius = 1/2 × diameter

Here diameter is given as 11 cm.

Hence Radius = 1/2 × 11 cm.

= 11/2 cm.

= 5.5 cm.

Write the given equation of the line that passes through the given points <br>(4,0) and (0,2)​
kondaur [170]

Answer:

y= -1/2x + 2

or y = -0.5x + 2

Step-by-step explanation:

Use the slope formula to get the slope:

(y2-y1)/ (x2-x1)

(2-0)/(0-4)

2/-4

-1/2

Plug in any point in Point-Slope Formula:

y - y1 = m(x-x1)

y- 0 = -1/2 (x -4)

y = -x/2 + 4/2

y= -1/2x + 2
