Not sure if you still need the answer

But it's 120+20[tex]\pi[/tex]

Because the 3 boxes in the middle are cubes, all three are 10x10, and perimeter of a cube is each side added up.

All together it would be 40+40+40 which equals 120.

Then for the semi-circles, the perimeter formula is 1/2([tex]\pi[/tex]d) d standing for diameter. Since we can tell that the diameter takes up 2 full cubes, we know that the diameter is 20. However since it's a semi-circle we cut that in half. So 10[tex]\pi[/tex]

10[tex]\pi[/tex]+10[tex]\pi[/tex]=20[tex]\pi[/tex]

So then your final answer is 120+ 20[tex]\pi[/tex]

Answer:

The measure of the first angle is 32° and the measure of the second angle is 49°. (h = 32° & c = 49°)

Step-by-step explanation:

For the first triangle, we know that when you add up all the angles in a triangle, you'll end up with 180°. Keeping that in mind, all you have to do to find the third angle is add up the two we already know and subtract it from 180°.

1. 58° + 90° = 148°  -->  I know that the second angle is 90° because it's a right

180° - 148° = 32°           triangle.

2. 82° + 49° = 131°

180° - 131° = 49°

Hope this helps,

Hedgehog68

Angle H is 32, Angle C is 49

A triangle equals to 180 degrees in total, the first triangle gave me 58 and 90 as starting angles so I subtracted those 2 from 180 and got 32
The second triangle gave me 82 and 49 so I subtracted those 2 from 180 and got 49

find the x-intercepts of the function g(x)=8x^{2} −10x−3

Which of the relationships below represents a function with the same rate of change as the function y=x-4?

Answers

Answer:

D

Step-by-step explanation:

The slope for the first one is 1 since x stands alone. You have to find the slope for each, and find the one that matches, so divide the change in y over change in x, or for the graphs find where the points are, find the difference in the y and x values and do change in y over change in x. For A, the slope would be -1, so it wouldn’t work. For B, the slope would be -5/4, so it wouldn’t match. For C, the slope would be -4/2, so it wouldn’t be a match. D the slope would be 1 so it is the only one that matches.
