Answer:

- 23/15 or - 1 8/15

Step-by-step explanation:

When you want to subtract fractions, you first want to see if they have the same denominator. In this case, there isn't a common denominator so we need to make it so there is. Since 15 is the larger one and a multiple of 3, we can change -6/3 to -30/15 by multiplying the top and bottom by 5. Now the double negatives cancel each other out so instead of -30/15 - (-7/15), it will be -30/15 + 7/15. Add them together and you get -23/15.

What is the length of the missing side? What is the area of the figure?<br>Show ALL work.​
guajiro [1.7K]

Answer:

Missing side=25 units.

Area of the figure= 470 sq units.

Step-by-step explanation:

The figure is made up of a rectangle and a triangle.

To get the base of the triangle, we find the difference between the two parallel sides, that is, 16ft and 31 ft.

31ft-16ft=15ft  

The height of the triangle is 20 since it is parallel and equal to the length of the rectangle.

We therefore use pythagoras theorem to find ?

a²+b²=c²

15²+20²=c²

625=c²

c=25

ii. The figure is a trapezium therefore we use the following formula to find the area.

A= 1/2(a+b)h, where a and b are the two parallel sides. and h the distance between them.

=(1/2)(31+16)×20

=470 sq units

I have no idea how to do this, someone help me
julsineya [31]
Try this:
1) for square a=5*2=10.
for circle r=5.
2) for square S'=10²=100; for circle S°=πr²≈78.54.
3) for half of circle S₁=0.5*78.54=39.27
4) for shaded region S=S'-S₁=100-39.27≈60.73
