Anyone know how to solve these

Mathematics
1 answer:
natulia [17]3 years ago
8 0

Answer:

1: 64π

2: 49π and 153.86

Step-by-step explanation:

For the first one we know that it has a diameter of 16 which means it has a radius of 8 (half the diameter)

To find the area of a circle use the following formula

π*r² where r is the radius

This means that the first answer is π*8^2

which is 64π

For the second one it's the same deal but the radius is 7

so the answer is 49π

Can someone please help me with this
UNO [17]
Ok so we know that student tickets cost $5, and adult tickets cost $8. We also know that the total no. of tickets sold was 150.

Let's make the amount of student tickets sold be S, and the no. of adult tickets sold be A.

We know that tickets sales amounted to $1,020, so:
8A + 5S = 1020
And:
A + S = 150. Multiply this by 5;
5A + 5S = 750

When you subtract the two equations;
(8A+5S) - (5A+5S) = 1020-750
So 3A = 270
A = 90
So 90 adult tickets were sold.
S = 150 - 90
= 60
So 60 student tickets were sold (although you don't need this as part of your answer)

Hope this helped

Consider the following regular decagon. Choose the correct card to fill in the blanks below. 30° 36° 60 72° 5 10 15 20 of Rotati
pochemuha

The decagon can be divided in 10 equal parts, so if a full rotation is of 360º, a one tenth rotations will be of 360º/10= 36º

So if you rotate the decagon by a multiple of 36º the rotation will be onto itself, i.e. the figure will look as if it wasn't moved.

From the choices given, the angle that will rotate the angle counterclockwise onto himself will be multiple of 36º, the only one is 72º

This figure has 5 lines of symmetry that cross each vertex and 5 lines of symmetry that cross form the midpoint of one side to the midpoint of the oposite side. This is a total of 10 lines of symetry.

So you can reflect the decagon 10 different ways.

The correct choice is C: 36º, 72º, 10, 5

What is the value of z?<br><br> Enter your answer in the box.
Georgia [21]

Answer:

23

Step-by-step explanation:

Because the angles of a triangle always add up to 180°, you can set up an equation like this.

62+95+z=180

157+z=180

157-157+z=180-157

z=23
