$4500 in to the ratio 4:3:2 please help

Mathematics
1 answer:
Igoryamba3 years ago
5 0

Answer:

$2000:$1500:$1000

Step-by-step explanation:

So in order to split $4500 into that proportion, we need to multiply the value by the corresponding ratios to split it properly.

There are 4 + 3 + 2 = 9 total parts to the ratio.

We know that we want the first part of the ratio to be 4/total. So we can say that:

$4500 x 4/9 = $2000. This is the first part of the ratio.

We then know the middle part of the ratio is 3/total. So we can say that:

$4500 x 3/9 = $1500. This is the middle part of the ratio.

Finally, we know that the last part of the ratio is 2/total. So we can say that:

$4500 x 2/9 = $1000. This is the last part of the ratio.

Put it all together, and we get $2000:$1500:$1000.

I hope this helps!

A model rocket is launched with an intitial upupward velocity of 202 ft/s. The rocket’s height h (in feet) after seconds is give
dsp73

Given that the height of a object thrown within a gravitational field is given as a quadratic equation in time, <em>t</em>, the time at which the object is at a specified height can be found by the quadratic formula

The values of, <em>t</em>, for which the height of the rocket is 82 feet are;

t = 12.21 seconds or t = 0.42 seconds

Question: <em>Parts of the question that appear missing but can be found online are (i) To find the values of the time, t, when the rocket's height is 82 feet and round answers to the nearest hundredth</em>

The known parameters of the rocket are;

The initial upward velocity of the rocket, v = 202 ft./s

The given function representing the height, <em>h</em>, (in feet) after <em>t</em> seconds is presented as follows;

H = 202·t - 16·t²

The unknown;

The time for which the height of the rocket is 82 feet

Method;

Substitute H = 82 feet in the height function equation and solve for <em>t</em> as follows;

When H = 82, we get;

82 = 202·t - 16·t²

Therefore;

16·t² - 202·t + 82 = 0

Dividing the above equation by <em>2</em> gives;

(16·t² - 202·t + 82)/2 = 0/2

8·t² - 101·t + 41 = 0

By using the quadratic formula, we get;

\mathbf{t = \dfrac{101 \pm \sqrt{(-101)^2 - 4 \times 8 \times 41} }{2 \times 8}  =  \dfrac{101 \pm \sqrt{8889} }{16}}

Therefore, the values of <em>t</em> given by rounding off to the nearest hundredth are;

t = 12.21 or t = 0.42

The values of the time, <em>t</em>, at which the height of the rocket is 82 feet are t = 12.21 seconds or t = 0.42 seconds

HELP WILL GIVE BRAINLIEST TO THE FIRST ANSWER!!!!<br> is 0=0 no solution or all real numbers???
kenny6666 [7]

Answer:

All real numbers

Step-by-step explanation:

Since 0 does equal 0, and value would be able to work. So any x-value will work. Infinite values for <em>x</em>, resulting in all real numbers.

Which is the best approximation for the value of √102?<br> A.10<br> B.11<br> C.50<br> D.51
Trava [24]
10, because when you use a scientific calculator you get 10.09950494
which would be round to 10 because after the decimal the number is 0 below 5 so 10 stays as 10
