Answer: 75. Hi! I learned something like this. Here is the explanation.

<h3>Step-by-step explanation: </h3><h3>So, I am not sure, but this is what I think. You would write it like this 30 kilograms equals 100%. Then, you would put the 100 percent over the 25 percent. So, it would look like this: 10% / 25% Then, you would multiply 30 times 25, because you can just multiply by 25 and not have to worry about the percent. 30 times 25 would give you 750 and then you would divide 750 divided by 10 and you would get 75.</h3><h3></h3><h3>Therefore, I think the answer is 75 kilograms of juice. </h3><h3>I hope this helps! </h3><h3></h3><h3>Sorry if this is wrong. </h3>

Mkey [24]

The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).

<h3>What is the parabola?</h3>

It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.

The function f(x) = 5x² + 40x

Then add and subtract 80, then we have

f(x) = 5x² + 40x + 80 – 80

f(x) = 5(x² + 8x + 16) – 80

f(x) = 5(x + 4)² – 80

The vertex of the parabola will be at (–4, –80).

More about the parabola link is given below.

A train travels at 100 milers per hour. An equation can be written that compares the time (t) with the distance (d). Define the
Alenkasestr [34]

Answer:

The domain is t ≥ 0

The range is D ≥ 0

Step-by-step explanation:

rate = \frac{distance}{time}

D(t) = 100t + d₀

t is the time measured in hours.

d₀ is the initial position of the train.

We can assume the distance they go is not negative so...

The domain is t ≥ 0

The range is D ≥ 0

Find the number of steel ball bearings, each of diameter 0.7 cm, that can be made from 1kg of steel, given that 1cm cubed of ste
dimulka [17.4K]

Answer:

Ball Bearing Volume = (4 / 3) * PI * radius ^3

Volume = (4 / 3) * 3.14159265 * (.35)^3

Volume = (4 / 3) * 3.14159265 * 0.042875

Volume = 0.17959438 cc

1 cc of steel = 7.8 g

Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc

1 kg = 128.205 cc

Number of ball bearings we can make = 128.205 / 0.17959438

Equals 713.86
