What percent of the games did Jay win?
Answers
To find the answer we first have to find the value of each percent, to do this we divide 100 by 350, that gets us approximately 0.286. We know that he won 154 of them we then multiply 154 by 0.286 to get the percentage of games he won and we get 44.044.
Answer:
44%
Step-by-step explanation:
154 ÷ 350 x 100 is 44%

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]

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,

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

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.
