Which expression of signed decimal numbers has a positive quotient?

Mathematics
1 answer:
melomori [17]3 years ago
7 0

Answer:

it would be -1.7 / -10.06 because if you divide 2 negative numbers than you get a positive number and if you divide a negative and a positive number than it would be negative

Hope this helps you ❤️

Jack buys a bag of 5 apples each equal in size he eat 1/2 of one Apple what fraction did he eat
Karo-lina-s [1.5K]
You have 4\frac{1}{2} apples left. 
You have 5 whole apples, you took one whole apple out, which equals 4 whole apples left. Then with the whole apple you took out, you ate \frac{1}{2} of it.
 Jack ate \frac{1}{2} of an apple in 5 apples. 
If you say that Jack ate \frac{1}{2} of 3 apples, then he ate 1\frac{1}{2} apples. So there isn't any difference when he ate \frac{1}{2} of an apple.

In 30 minutes, a television station plays 8.5 minutes of commercials. The equation m + 8.5= 30 gives the length m in minutes of
zubka84 [21]
The solution to the equation would be 21.5

Why?

If you do the equation backwards

30 - 8.5 = x

You would get 21.5
You can plug it into the first equation to check!

33. Suppose you were on a planet where the
tatyana61 [14]

<u>Answer:</u>

a) 3.675 m  

b) 3.67m

<u>Explanation:</u>

We are given acceleration due to gravity on earth =9.8ms^-2

And on planet given = 2.0ms^-2

A) <u>Since the maximum</u><u> jump height</u><u> is given by the formula  </u>

\mathrm{H}=\frac{\left(\mathrm{v} 0^{2} \times \sin 2 \emptyset\right)}{2 \mathrm{g}}

Where H = max jump height,  

v0 = velocity of jump,  

Ø = angle of jump and  

g = acceleration due to gravity

Considering velocity and angle in both cases  

\frac{\mathrm{H} 1}{\mathrm{H} 2}=\frac{\mathrm{g} 2}{\mathrm{g} 1}

Where H1 = jump height on given planet,

H2 = jump height on earth = 0.75m (given)  

g1 = 2.0ms^-2 and  

g2 = 9.8ms^-2

Substituting these values we get H1 = 3.675m which is the required answer

B)<u> Formula to </u><u>find height</u><u> of ball thrown is given by  </u>

 \mathrm{h}=(\mathrm{v} 0 * \mathrm{t})+\frac{\mathrm{a} *\left(t^{2}\right)}{2}

which is due to projectile motion of ball  

Now h = max height,

v0 = initial velocity = 0,

t = time of motion,  

a = acceleration = g = acceleration due to gravity

Considering t = same on both places we can write  

\frac{\mathrm{H} 1}{\mathrm{H} 2}=\frac{\mathrm{g} 1}{\mathrm{g} 2}

where h1 and h2 are max heights ball reaches on planet and earth respectively and g1 and g2 are respective accelerations

substituting h2 = 18m, g1 = 2.0ms^-2  and g2 = 9.8ms^-2

We get h1 = 3.67m which is the required height
