There are 8 black socks and 20 white socks. 5 socks times 4 = 20 white socks, and 2 socks times 4 = 8 black socks. So, Pa has 8 black socks.
Answer:
x = 8.6603 m
Step-by-step explanation:
If x is the length of a side of the square, the area of the square will be x^2.
So, if the area of the square is 75 ft2, we can formulate the quadratic equation:
x^2 = 75
Now, solving the equation, we just need to make the square root of 75:
x = sqrt(75) = ±8.6603
x1 = 8.6603
x2 = -8.6603
Now, as x represents the length of a side of the square, and measurements can't be negative, we take only the positive value, so:
x = 8.6603 m
Answer:
128
Step-by-step explanation:
Hey There!
So the rule about interior angles of a trapezoid
is that the angles that lie on the segments that are not parallel are supplements
so essentially what I'm saying is that angle R and angle U are supplementary angles so to find x we do
180=15x+8+7x-4
step 1 combine like terms
15+7=22
8-4=4
now we have
180=22x+4
step 2 subtract 4 from each side
180-4=176
now we have
176=22x
step 3 divide each side by 22
176/22=8
so x=8
now we plug in 8 to 15x+8
8x15=120
120+8=128
so we can conclude that angle R = 128
