Answer:

Area  = 10 units

<u>Skills needed: Triangle Theory, Substitution of Values</u>

Step-by-step explanation:

1) We are given that the formula to finding the area of the triangle is \frac{1}{2}bh.... this essentially means that it is:  \frac{1}{2} times base (b) times height (h)

2) We can then use substitution to solve this. IN the diagram shown there, 4 is the base, and the height is 5 (since b = base, and h = height).

Area is \frac{1}{2} * b * h in general (the * means multiplication)

Substitute in the values and it is: \frac{1}{2} * 4 * 5

--> 4*5=20

--> \frac{1}{2} * 4*5 = \frac{1}{2} * 20 = 10

1/2 of 20 is ten, so that is how we arrive at that final answer.

Hope you understand, have a great day :)

Since the question says she plans to work "more than" the hours last month, it is h>74.25 (second choice down). If it said "more than or equal to," it would be the third option down.

ANSWER: h>74.25 (second choice down)

Hope this helps! :)

A rectangular billboard image is 5 ft wide and 4 ft high. If the available billboard space is 25 ft by 15 ft, what are the dimen
Lapatulllka [165]

Answer:

18¾ ft × 15 ft

Step-by-step explanation:

The dimensions of the billboard are 25 ft by 15 ft.

The dimensions of the image are 5 ft by 4 ft  

Case 1.<em> Expand the length of the image to 25 ft. </em>

We have multiplied the length by five, so we must multiply the width by five.

w = 5 × 4 = 20 ft. That's too big. The image will overflow the billboard

by 5 ft.


<em>Case 2. </em><em>Expand the width of the image to 15 ft. </em>

We have multiplied the width by 15/4, so we must multiply the length by 15/4.

l = 15/4 × 5 = 75/4 = . That will fit, with 6¼ ft left over.

The expanded image will be 18¾ ft × 15 ft.

In the image below, the big rectangle represents the billboard, and the red rectangle represents the original image.

The pink rectangle represents the dilation of the original image to a width of 15 ft.
