Answer:

The answer is √5 .

Step-by-step explanation:

You have to rationalize the fraction in order to get rid of surd in the denorminator by multiplying √3 to both numerator amd denorminator :

$\frac{ \sqrt{15} }{ \sqrt{3} }$

$= \frac{ \sqrt{15} }{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} }$

$= \frac{ \sqrt{15} \times \sqrt{3} }{ \sqrt{3} \times \sqrt{3} }$

$= \frac{ \sqrt{45} }{3}$

$= \frac{ \sqrt{9 \times 5} }{3}$

$= \frac{3 \sqrt{5} }{3}$

$= \sqrt{5}$

Find "C" when "F" = 120.<br>Round to tenths.<br> C= 5F-160 /9

GenaCL600 [577]

Answer:

C = 48.9

Step-by-step explanation:

C= 5F-160 /9

C= (5F -160)/ 9

Put F =120

C = (5(120) - 160)/9

C= (600 - 160)/9

C = 440/9

C = 48.89≈ 48.9

Pleaseee help me with these i did some but just wanna make sure I'm in the same page if its right. please explain how you got it

Sergeeva-Olga [200]

1. P = 2(9) + 2(4.5)
P = 18 + 9
P = 27 m

2. P = 5.2(2) + 1.3(2)
P = 10.4 + 2.6
P = 13 ft

3. P = 12.9(2) + 4.7(2)
P = 25.8 + 9.4
P = 35.2 cm
