<h3><u>Question:</u></h3>

In a video game, Clare scored 50% more points than Tyler. If c is the number of points that Clare scored and t is the number of points that Tyler scored, which equations are correct? Select all that apply.

the options are

A. c=1.5t

B.c=t+0.5

C. c=t+0.5t

D. c=t+50

E.c=(1+0.5)t

<h3><u>Answer:</u></h3>

Options A, C, E are correct

The correct equations are c = 1.5t and c = t + 0.5t and c = (1 + 0.5)t

<h3><u>Solution:</u></h3>

Let "c" be the number of points clare scored

Let "t" be the number of points tyler scored

Given that,

Clare scored 50% more points than Tyler

Points scored by clare = points tyler scored + 50% of Tyler points

c = t + 50 % of t

Therefore, on solving, we get

c = t + \frac{50}{100} \times t\\\\c = t + 0.5t

Thus option c is correct

On simplfying we get,

c = t + 0.5t = 1.5t

c = 1.5t

Thus option A is correct

c = t + 0.5t

On taking "t" as common we get,

c = t(1 + 0.5)

Thus option E is also correct

What is the area of this triangle.
chubhunter [2.5K]

Answer:

13 square units

Step-by-step explanation:

You <em>could</em> calculate the length of each side using Pythagorean theorem, then use Heron's formula to find the area.  But there's an easier way: find the area of the rectangle that contains the triangle, and subtract the areas of the smaller triangles in the corners.

The area of the rectangle is 4 × 7 = 28.

The area of the upper left triangle is ½(2)(4) = 4.

The area of the upper right triangle is ½(3)(5) = 7.5.

The area of the lower right triangle is ½(1)(7) = 3.5.

So the area of the triangle is:

28 − 4 − 7.5 − 3.5 = 13

Why are the factors in your multiplication sentences in a different order​
Diano4ka-milaya [45]

In multiplication, the order doesn't matter.

2 rows of 7 and 7 rows of 2 is the same.

If you have seven 2's, that's the same as two 7's.

See here:

2 + 2 + 2 + 2 + 2 + 2 + 2 = 14

7 + 7 = 14

Or:

2 * 7 = 7 * 2 = 14
