Answer:

18/36 in simplest form is 1/2.

1 5/8 to an improper fraction is 13/8

19/5 to mixed fraction is 3 4/5 in simplest form

Step-by-step explanation:

18 and 36 in share a common denominator of 18. 18 divided on 18 is 1. 36 divided on 18 is 2. so 1/2 is equivalent to 18/36.

1 5/8 equals one whole (8) plus 5. 8 + 5= 13. 13/5 is your answer

19 divided on 5 is 3.8. 3.8 converted to a fraction is 3 and 0.75. 0.75 in fraction form is 4/5. your answer is 19/5 = 3 4/5 or 3 and 8/10.

Answer:

$E_{T} = 36.84 J$

Step-by-step explanation:

La energía mecánica total está dada por:

$E_{T} = E_{c} + E_{p}$

$E_{T} = \frac{1}{2}mv^{2} + mgh$

En donde:

m: es la masa = 150 g

v: es la velocidad = 0.8 m/s

h: es la altura = 25 m

g: es la gravedad = 9.81 m/s²

$E_{T} = \frac{1}{2}mv^{2} + mgh = \frac{1}{2}0.15 kg*(0.8 m/s)^{2} + 0.15 kg*9.81 m/s^{2}*25 m = 36.84 J$

Por lo tanto, la energía mecánica total es 36.84 J.

Some questions have the form y = kx, where k is a number. Drag each question to the correct category below. ( X = y/2 ),( y = .1

fomenos

Answer:

Has the form y = kx

( y = 0.11x)

(y = 0.04x)

Can be put into form y = kx

(z/x = 9)

Other

(5 = xy)

( x = y/2)

Step-by-step explanation:

y = kx

( y = 0.11x)

(y = 0.04x)

kx = y

(z/x = 9)

-----------

( x = y/2 )

( x - 5 = y)

(5 = xy)

According to government birth statistics, the probability of a woman

lyudmila [28]

To find the probability of not having twins, we can subtract the probability of having twins from 1. This is because probabilities always add up to 1.

1 - 0.015 = 0.985

The probability of not having twins is 0.985.

Hope this helps!! :)
