Its a right angled triangle. You have C and have B all you need to find is A. usually for a question like this you would use the Pythagorean theorem which is A2+B2=C2 but since we already have c we will use C2-B2=A2
Now we fill in the values. (21)2-(9)2=A2
441-81=360^2 so now with the 360^2 we have to squareroot it so the square root of 360 is 18.973f
Answer:
The first one is 79
The second one is 26
I hope this helped! :D
Step-by-step explanation:
For the first one you just plug in 23 into x so it would be 3(23) + 10 = x
For the second one you just plug in 88 into g so it would be 88 = 3x + 10
Answer:
9x+5y-5z
Step-by-step explanation:
if you need an explanation I can put it in the comments :)
Answer:
12/15 and 16/20
Step-by-step explanation:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
12/15 simplified is 4/5.
16/20 simplified is 4/5
Answer:
The Y-intercept value for the regression equation is -2
Step-by-step explanation:
The linear regression has the form: y = a + b*x, where a is the Y-intercept and b is the slope. To find the a compute the following:
a = MY - b*MX
where MX and MY denotes mean for the X and the Y respectively. Replacing:
a = 6 - 4*2 = -2
