Daniel [21]

Answer:

60 ft²

Step-by-step explanation:

The reason being that you take the height of 8 and multiply it by the width of 15. 8×15=120 Then since a triangle is half of a square you would halve it. 120÷2=60 Which would then give you your answer.

The line of symmetry is involved in which transformation?
BARSIC [14]

Answer:

Reflection

Step-by-step explanation:

The line of symmetry is involved in reflection transformations- when you reflect a graph, you can see the line that separates the original image from its reflected one.

This line acts as a line of symmetry because it divides the mirror images.

Red and grey bricks were used to build a decorative wall. The number of red bricks/number of grey bricks was 5/2. There were 140
Airida [17]
To find the number of red bricks used, you can create a part to part to whole ratio from the simple ratio of red to grey brick they give.

Then, use the total to create an equivalent ratio with the actual total number of bricks (140).

<u>5 red </u>    <u>100 red</u>
<u>2 grey</u> =  <u>40 grey</u>
7 total   140 total
<u>
</u>Each time, the simple ratio was multiplied by 20 to get the actual totals for each color.
<u>
</u>There were 100 red bricks used.<u>
