Answer:
1. b=39.497
2. c=3.606
3. a=18.974
Step-by-step explanation:
1.
41^2-11^2=b^2
1681-121=b^2
b^=1560
b=39.497
2.
2^2+3^2=c^2
4+9=c^2
c^2=13
c=3.606
3.
21^2-9^9=a^2
441-81=a^2
a^2=360
a=18.974
Hi Brainiac
7/8 =?/48
Let's replace the unknown place by x
7/8 = x/48
Cross multiply
(7)(48)= (X)(8)
336 = 8x
Flip it
8x = 336
Divide both sides by 8
8x/8 = 336/8
x= 42
The answer is C
Now if you wanna see if the answer is good just replace 42 in blank space
7/8 = 42/48
Now didivde 7 by 8 and divide 42 by 48
7/8= 0.875
42/48= 0.875
The answer C is correct
I hope that's help:)
If you have questions please let me know :)
Hey!

Find the slope:
------------------------------------------------
Slope Intercept Form:
y = mx + b
m = slope
b = y-intercept
Slope = -3/5
Y-intercept = 9/5
Answer: y = -3/5 + 9/5
------------------------------------------------
Point Slope Form:
y - y1 = m(x - x1)
You can use either of the points.
Answer:
y - 3 = -3/5(x - 2)
or
y - 0 = -3/5(x - 3)
------------------------------------------------
Hope This Helped! Good Luck!
Answer:
-32
Step-by-step explanation:
10–{22–[(−9)+(−11)]}
Work inside out
10–{22–[(-20)]}
Subtracting a negative is adding
10–{22+20}
10 - 42
-32
Answer:
In descending order, 1, 4, 3
