Answer:
l
Step-by-step explanation:
Two sides are the same length; one angel measures 90°.
Answer:
17/49 or about 34.7%
Step-by-step explanation:
George has 85 cards out of 245 cards that are pitchers. Whever you hear "out of", it means to divide.
85/245 are pitchers.
you can simplify since 5 fits in both of those numbers
5*17=85
5*49=245
So, 17/49 or about 34.7%
Ok so I like to go in steps with these questions- first draw a picture and identify your variables.
W=width
L= 3w-1
Now we know that length times width gets us area so we plug in our variables into the area equation.
200 = w(3w-1)
When you foil that equation you end up with a quadratic : 3w^2-w-200 = 0
Either factor that or use the quadratic formula to get
w= 8.33 and w= -8
Since you can't have a negative dimension you need to use 8.33 and plug it back into your length equation.
Final answer:
w= 8.33ft
l= 23.99ft
*Now I simplified the decimals a little bit so you end up with 199.8ft^2 for the area so just add a few decimals on here and there*
Subtract the 2 equations
7x+2y=-19
- -x+2y = 21
--------------------------
8x +0y=-2
x= -1/4
