HELP PLEASE!!! I need help with this question!

Answer:

$\large\boxed{PS=10\sqrt5}$

Step-by-step explanation:

ΔPQS, ΔRQP and ΔRPS are similar (AA). Therefore the sides are in proportion:

$\dfrac{QR}{RP}=\dfrac{RP}{RS}$

We have:

$QR=5,\ RS=20$

Substitute:

$\dfrac{5}{RP}=\dfrc{RP}{20}$ cross multiply

$RP^2=(5)(20)\\\\RP^2=100\to RP=\sqrt{100}\\\\RP=10$

Use the Pythagorean theorem:

$PS^2=PR^2+RS^2$

Substitute:

$PS^2=10^2+20^2\\\\PS^2=100+400\\\\PS^2=500\to PS=\sqrt{500}\\\\PS=\sqrt{100\cdot5}\\\\PS=\sqrt{100}\cdot\sqrt5\\\\PS=10\sqrt5$

3/4 of a number minus -16 equals 28. What is the number ?

Zigmanuir [339]

Answer:

The number is 16

Step-by-step explanation:

3/4 n- (-16) = 28

3/4 n + 16 = 28

Subtract 16 from each side

3/4 n +16-16 = 28-16

3/4 n =12

Multiply by 4/3 to isolate n

4/3 * 3/4 n = 12 * 4/3

n = 16
