Answer:
15.2
Step-by-step explanation:
She makes 31% of her foul shots
she took 49 shots
the number of foul shots is 31% of 49 shots
=31% * 49
=0.31 * 49
= 15.19
Answer:
For a trapezium of height H, parallel side 1 X, and parallel side 2 Y, the area is:
A = (1/2)*H*(X + Y)
with this we can complete the table.
a)
Here we know:
X = 7cm
Y = 11cm
H = 6cm
Then: A = (1/2)*6cm*(7cm + 11cm) = 54 cm^2
b)
Here we know:
X = 8 m
Y = 10 m
A = 126 m^2
Then:
126 m^2 = 0.5*H*(8m + 10m)
126 m^2 = H*9m
126 m^2/9m = H = 14m
Then the height of this trapezoid is 14m
c)
Here we know:
X = 5mm
H = 8mm
A = 72 mm^2
Then:
72 mm^2 = 0.5*8mm*(5mm + Y)
72 mm^2 = 4mm*(5mm + Y)
72mm^2/4mm = 5mm + Y
18 mm = 5mm + Y
18mm - 5mm = Y
13 mm = Y
Then the parallel side 2 is 13 mm long.
You basically would use how long they are. If you had a strip of 1/2 and a strip of 3/4... with blocks they wouldn't be the same length. The 3/4 blocks would be greater.
However if you matched a 1/2 strip with a 3/6 strip, you can see that they are the same length and are equivalent.
Of course their is a way to do it mathematically but let me know if you want to see that.

Step-by-step explanation:
Equation:
12x + 7 = 55
12x = 55 - 7
12x = 48
x = 4
