Answer:

(d) 45% play basketball; 55% play soccer

Step-by-step explanation:

You just need a little number sense here. The total number who play sports is the number in the lower right of the table: 120.

The fraction who are males playing basketball is 42/120. Comparing that to 45/100, we see it cannot be 45%. (a) is false.

The fraction who are males is 72/120, more than half, so cannot be 40%. (b) is false.

Looking at males who play basketball, we have already determined the fraction 42/120 is well below 65%. (c) is false.

The fraction who play basketball is 54/120 = 45%. (d) is true.

Find the missing length of the following trapezoid

Schach [20]

Answer:

1) The length of $DC$ is 20.

2) The length of $PS$ is 17.

Step-by-step explanation:

1) If $DR = RE$ and $CS = SB$ , then we can use the following proportionality ratio:

$\frac{DE}{DR} = \frac{32 - x}{26 - x}$ (1)

Where $x$ is the length of segment $\overline{CD}$ .

If $DE = 2\cdot DR$ , then the value of $x$ is:

$2 = \frac{32-x}{26-x}$

$52 - 2\cdot x = 32 - x$

$20 = x$

The length of $DC$ is 20.

2) If $QV = VP$ and $RW = WS$ , then we can use the following proportionality ratio:

$\frac{QP}{QV} = \frac{x-7}{12-7}$ (2)

Where $x$ is the length of segment $\overline{PS}$ .

If $QP = 2\cdot QV$ , then the value of $x$ is:

$2 = \frac{x-7}{5}$

$10 = x-7$

$x = 17$

The length of $PS$ is 17.

18. How can you tell if a fraction will have a repeating decimal

GaryK [48]

Terminating and Repeating Decimals. Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of , then you have a terminating decimal.
