For 7 divide 180 into 3
That will be 60 degrees for all three of them
Now for 8 there is one line at the center that cuts the horizontal line, so we know that the angles on either side will be 90
So 24 and 21 will be 90, they are both on either sides of the vertical line.
We know 25 is 15 degrees so for 26
Subtract 15 from 90
75 degrees is the answer. This is the same for even 23
So,
21 is 90 degrees
22 is 15 degrees
23 is 75 degrees
24 is 90 degrees
25 is 15 degrees
And lastly,
26 is 75 degrees.
Hope this helps:)

The Ferris wheel shown makes 16 revolutions per ride. How far would someone travel during one ride? Round your final answer to t
sertanlavr [38]

Complete question :

The diameter of the ferris Given is 63 feets

Answer:

3165 feets

Step-by-step explanation:

Given that :

Diameter of ferris = 63 feets

Recall :

Circumference of a circle = 2 * pi * Radius

Or

Circumference = pi * d

Hence,

Circumference of wheel = 3.14 * 63 = 197.82 feets

Distance traveled during one ride :

Circumference of wheel * number of revolutions

197.82 * 16 = 3165.12

= 3165 feets (nearest whole number)

A single gram of a certain metallic substance has 0.52 g of copper and 0.25 g of zinc the remaining portion of the substance is
andrezito [222]
Ben's estimate gives 7 g of nickel; the actual amount is 8.03 g.

In 1 g of the substance, there is 0.52 g of copper and 0.25 g of zinc; this gives 
0.52+0.25 = 0.77 g of the substance.

The remaining part of the substance is nickel:
1-0.77 = 0.23 g of nickel.

Using Ben's estimate, 0.2 g of nickel per gram of substance, we have
0.2(35) = 7 g of nickel in 35 g of the substance.

The actual amount is 0.23(35) = 8.03 g of nickel in 35 g of the substance.

Find the perimeter of parallelogram ABCD with vertices A(–5, 6), B(2, 6), C(1, –2), and D(8, –2).
zavuch27 [327]
Since in A and B we have the same y value, 2-(-5)=7 and that's one side. For A to C (we connect A to C since they are both the ones on the left), we use the distance formula to get sqrt((-5-1)^2+(6-(-2))^2=sqrt(36+64)=sqrt(100)=10. Since there are 2 equal pairs of sides in a parallelogram, we get 7*2+10*2=34
