175 mm= how much m HELP ME CAUSE IDK

A scientist had 3/4 liter of solution. HE used 1/6 of the solution for an experiment..How much solution did the scientist use fo

Leviafan [203]

Answer:

$\frac{1}{8}\ liter$

Step-by-step explanation:

we know that

To find out how much solution the scientist used for the experiment multiply 3/4 by 1/6

so

$(\frac{3}{4})(\frac{1}{6})=\frac{3}{24}\ liter$

simplify

$\frac{3}{24}=\frac{1}{8}\ liter$

Find a unit vector that is parallel to the line tangent to the parabola y = x2 at the point (5, 25).

BartSMP [9]

The line tangent to $y=x^2$ at the point (5, 25) as slope equal to $y'$ when $x=5$ :

$y=x^2\implies y'=2x\implies\mathrm{slope}=10$

Then the tangent has equation

$y-25=10(x-5)\implies y=10x-25$

But only the slope is important here; any vector $t(1,10)$ is parallel to this line. Then a unit vector would be obtained by dividing this vector by its norm. Let $t=1$ for simplicity; then the unit vector is

$\dfrac{(1,10)}{\sqrt{1^2+10^2}}=\left(\dfrac1{\sqrt{101}},\dfrac{10}{\sqrt{101}}\right)$

Is 64 cups bigger than 30 pints

sattari [20]

Hello!

Yes indeed,

It is Bigger than 30 Pints, Why?

Well because 1st we have to remember that 1 cup = 0.5 pints, which is like 1/2
And also, remember that if there were 30 pints, then that would = to 60 cups, but in this case we get 64, which of course is seen bigger because of 4 cups more.

So yes as i said in the beginning, 64 IS bigger than 30 Pints because if it were equal, it would then have to be 60 Cups instead of 64.

Hope this Helps! Have A Wonderful Day! :)

A circle has a diameter of 25cm. How far from the centre of this circle is a chord 16cm long? Draw a picture before you start.

yan [13]

Answer:

The cord is 9.6 cm away from the centre of the circle.

Step-by-step explanation:

See The Image First

The image below shows a picture of everything that’s given, labeled, and drawn in the circle.

Description of the Picture:

You can use the Pythagorean to find the what the distance (the length b) the cord is from the center. You can use the radius as the hypotenuse. The radius is half of the diameter, and the diameter is 25. So the radius is 12.5, which means that 12.5 is the hypotenuse of the triangle (also known as side c). The whole length of the cord is 16cm long, and we can use half of the cord, which is 8cm, for the triangle. So we know two sides already: the hypotenuse (the radius) and the length a of the triangle (half of the length of the cord).

To Solve (variables a, b, and c, are in italics so you don’t get confused):

⇒ Use the formula of the Pythagorean Theorem ( $a^{2}+b^{2}=c^{2}$ ), where b is the length of the distance from the cord to the centre of the circle (what we need to find out), a is the length of the side of the triangle (half of the cord size – 8cm), and c is the hypotenuse (the radius – 12.5cm). So plug the given values of b and c into the formula:
