Answer:

to find the area, multiply the base times the height and divide it by two. we do not have the picture of the triangle, so we cannot answer this but here is the formula

Drag each figure to show if it is similar to the figure shown or why it is not similar

Margarita [4]

Answer:

Step-by-step explanation:

The given figure is a rectangle having length = 9 yd and width = 3 yd

Now we will check each figure

Figure one- rectangle with length = 18 yd and width = 9 yd

For similarity of both rectangles ratio of length should be equal to ratio of widths.

$\frac{3}{9}\neq\frac{9}{18}$

So rectangles are not similar.

Figure 2- rectangle with length = 3 yd and width = 6 yd

$\frac{9}{3}\neq \frac{3}{6}$

So figures are not similar.

Figure 3 - rectangle with length = 3 yd and width = 1 yd

$\frac{9}{3}=\frac{3}{1}$

Therefore, figures are similar.

Figure 4 -rectangle with length = 8 yd and width = 2 yd

$\frac{3}{2}\neq \frac{9}{8}$

So given rectangles are not similar.

Figure 5 - rectangle with length = 18 yd and width = 6 yd

$\frac{9}{18}=\frac{3}{6}$

So rectangles are similar.

Figure 6 - trapezoid with larger base = 18 yd and height = 6 yd

Since shapes of the given figures are not same so they are not similar.

I need help on this

IRINA_888 [86]

Answer:

Rate of change is slope

To calculate slope its

y2 - y1 / x2- x1 = slope

Just choose 2 random sets from the table.

I’m gonna go with (0,-10) and (2,20)

Now calculate slope

20 - (-10) / 2 - 0

Solve.

30 / 2

30/2 = 15

Rate of change is 15

Which graph represents no solution

Cerrena [4.2K]

Answer:

D. Parallel lines

Step-by-step explanation:

Lines which intersect have their point of intersection as the solution to the system of equations. If there is no solution then two lines do not intersect. The two lines must be parallel.

Arnold makes a chart to summarize what happens when light interacts with matter and is reflected. Which idea does Arnold need to

jasenka [17]

Answer:

In diffuse reflection, reflected rays move in different directions.

Step-by-step explanation:

Reflection refers to the bouncing off of light from a surface. Reflection can be regular or diffuse.

Regular reflection occurs when light bounces off a well polished surface while diffuse reflection occurs when light bounces off a rough surface.

During diffuse reflection, light is reflected in different directions.

You buy shrimp at the market. The shrimp cost $34.99 for two 2.5-pound bags. What is the unit rate of the shrimp in dollars per

schepotkina [342]

$34.99 ... 2.5-pound bags
$x = ? ... 1 pound

If you would like to know what is the unit rate of the shrimp in dollars per pound, you can calculate this using the following steps:

34.99 * 1 = x * 2.5
34.99 = x * 2.5 /2.5
x = 34.99 / 2.5
x = $13.996 = $14

The correct result would be $14.
