Answer:

11.9 cm

Step-by-step explanation:

1 in ≈ 2.54 cm

4.7 in ≈ 2.54(4.7) cm

2.54(4.7) = 11.938 cm

11.938 cm rounded to the nearest tenth is 11.9 cm.

Answer: 11.9

Step-by-step explanation:

The conversion rate is 1 inch to 2.54 centimeters. Using this we can setup the equation 4.7 in * \frac{2.54 cm}{1 in}. The inches units will cancel and you will end up with 11.938 cm. Rounded to the nearest tenth and you get 11.9.

If there are 1500 guests, only 1 of them brought a coupon for free admission to the carnival?
wlad13 [49]
So 1/50 brought the pass
x out 1500
1/50 = x/1500
cross multiply
1500 = 50x
divide both sides by 50
30 = x

You can expect for 30 out of the 1,500 to receive free admissions. 

Hope this helps

The value pie/2 is a solution for the equation 2sin^2x-sinx-1=0<br><br> true or false
Rasek [7]

Answer:

Yes, \frac{\pi }{2} is a solution

Step-by-step explanation:

Recall that sin(\frac{\pi }{2})=1. By replacing \frac{\pi }{2} in the given trigonometric equation, we get 0 (zero) as a result, so this value is a solution:

2*(sin(\frac{\pi }{2} ))^2-sin(\frac{\pi }{2})-1= 2*(1)^2-1-1=2-2=0

Which is the simplified form of the expression?
Scorpion4ik [409]

Answer:

1 / q^30.

Step-by-step explanation:

[(p^2)(q^5)]^-4 * [(p^-4)(q^5)]^-2

Using the law (a^b)^c =  a^bc :-

=  p^-8 * q^-20 * p^8 * q^-10

= p^(-8+8) * q^(-20-10)

= p^0 * q^-30

= 1 * q^-30.

= 1 / q^30.
