They are equal because if you divide 4÷1.0 your answer would be 0.4

Well, of you change the fraction into a decimal (divide the numerator by the denominator : 1 divided by 4), you get:

(the decimal from 1/4) 0.25 __ 0.4

It's not that hard from there: 0.25 < 0.4

No. Let's say we use 10 and 0.38. 1 X 10 is 10, so if anything is lower than 1, it will be lower than 10. Therefore, 0.38 X 10 is 3.8. This is less than the whole number, 10. Hope this is clear enough.

Is the product of 3⅝ x ⅔ greater than or less than 3⅝? explain without multiplying

almond37 [142]

So the question is
number times 2/3 is greater than or less than the sasme number
so let's say x
x times 2/3 is greater than or less than x
since 2/3 is less than 1, 2/3 is a fraction,
anything times a fraction will become smaller

therefor
3 and 5/8 times 2/3 is less than 3 and 5/8

the answer is LESS THAN

A ball is thrown from a height of 38 meters with an initial downward velocity of 3 m/s

ANTONII [103]

<h2>Hello!</h2>

The answer is:

The ball will hit the ground after $t=2.47s$

Since we are given a quadratic function, we can calculate the roots (zeroes) using the quadratic formula. We must take into consideration that we are talking about time, it means that we should only consider positive values.

So,

$\frac{-b+-\sqrt{b^{2} -4ac} }{2a}$

We are given the function:

$h=-5t^{2}-3t+38$

Where,

$a=-5\\b=-3\\c=38$

Then, substituting it into the quadratic equation, we have:

$\frac{-b+-\sqrt{b^{2} -4ac} }{2a}=\frac{-(-3)+-\sqrt{(-3)^{2} -4*-5*38} }{2*-5}\\\\\frac{-(-3)+-\sqrt{(-3)^{2} -4*-5*38} }{2*-5}=\frac{3+-\sqrt{9+760} }{-10}\\\\\frac{3+-\sqrt{9+760} }{-10}=\frac{3+-\sqrt{769} }{-10}=\frac{3+-27.731}{-10}\\\\t1=\frac{3+27.731}{-10}=-3.073s\\\\t2=\frac{3-27.731}{-10}=2.473s$

Since negative time does not exists, the ball will hit the ground after:

$t=2.473s=2.47s$

Have a nice day!

(-3 * 10 to the power of 4) * (2 * 10 to the power of -3)

gayaneshka [121]

-3*10= -30 to the 4th power is 810,000
10 to the -3 power is -1000 * 2 is -2000

810,000 * -2000 = -1,620,000,000
