Answer:

13

Step-by-step explanation:

First, we need to find the area of the rectangle that the triangle RST is in, which would be 4*5=20. Second, we need to subtract the three triangles so the remaining area would be the area of the triangle that we need to solve for. The sum of the areas of the three triangles would be: 1/2*2*5 + 1/2*2*2 + 1/2*4*3 = 5 + 2 + 6 = 13.

Answer:

  • x = 10
  • y ≈ 8.7

Step-by-step explanation:

Corresponding sides of these triangles are proportional, so you have ...

  x/5 = 20/x

  x² = 5·20 . . . . . . . cross multiply

  x = √100 = 10

and ...

  y/15 = 5/y

  y² = 15·5 . . . . . . cross multiply

  y = √75 ≈ 8.7

Find the surface area (the triangle are right triangles).
Igoryamba

Answer:

67.5

Step-by-step explanation:

Well area of a triange is 1/2bh so we can find the side closest to us by doing

1/2(3x4) which is 12

the other side would be 1/2 (3x5) which is 7.5

the bottom side would be 1/2(8x4) so 16

and 1/2 (3x8) so 12

1/2 (8x5) so 20

add those together to get 67.5

Hope this helped ya!

At a coffee shop, 70% of the customers buy a coffee drink, 30% buy food, and 20% buy both a coffee drink and food. Are buying fo
Shkiper50 [21]

Yes.

70% of the customers buy a coffee drink and 30% buy food.

The sum of it is 100% already.

So 20% of it just another addition of information since it cannot exceed 100% of percentage (100% + 20% = 120%).

It also contains a subset for both percentage.

Wendy goes to the gym every 4 days and swims every 6 days. If she went to the gym and swam today, in how many days will she do b
Mice21 [21]

In 12 days, Wendy will do the both again.

Step-by-step explanation:

Given,

Wendy goes to gym every 4 days

Wendy swims every 6 days

We will find the least common multiple of both the numbers in order to determine the number of days in which she will do both.

4 = 4,8,12,16,20,....

6 = 6,12,18,24,.....

Therefore;

The least common multiple of 4 and 6 is 12.

Thus,

In 12 days, Wendy will do the both again.
