How many times greater is the value of 3 in 300 than the value of the 3 in 30

Vikki [24]

Well it sounds like you mean smaller, not greater. 3/300 = 1/100 while 3/30 = 1/10. So 3 out of 300 is 10 times SMALLER than 3 out of 30.

∠B= please give me the answer!

Answer:

I think it's 45 degrees

Step-by-step explanation:

<c is 90 degrees and the interior of every triangle is 180 degrees so then we subtract 90 from 180 which is 90 so we divide 90 by two since b and a seem to be equal which is 45 degrees.

Find the point P along the directed line segment from point A(–13, 6) to point B(2, 20) that divides the segment in the ratio 2

VARVARA [1.3K]

Answer:

(-4, 14.4)

Step-by-step explanation:

The midpoint formula is expressed as;

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

Get X;

X = ax1+bx2/a+b

X = -13(2)+ 2(3)/2+3

X = -26+6/5

X = -20/5

X = -4

Get Y:

Y =ay1+by2/a+b

Y = 2(6)+3(20)/2+3

Y = 12+60/5

Y = 72/5

Y = 14.4

Hence the coordinate of point P dividing A and B in the ratio 2 to 3 is

(-4, 14.4)

During a biology course, Jacobi learned that the diameter of red blood cells can be written as 6.5x10 to the -3 power millimeter

madreJ [45]

Answer:

$\bold{0.0065}$

Step-by-step explanation:

Hi there!

Let's convert numbers in scientific notation to standard form.

$\bold{6.5x10^{-3} }$ => scientific notation

First, the coefficient is $\bold{6.5}$ .

So, we know part of our number.

Now, let's look at the exponent:

$\bold{-3}$

First of all, the exponent is $\bold{NEGATIVE}$ .

This means that we'll move the decimal point to the $\bold{left}$ .

Then, the 3 means we'll move the decimal point 3 units.

So, our number looks like so:

$\bold{0.0065}$

Hope it helps! Enjoy your day!

the equation below shows the relationship between the temperature in degrees celsius C in degrees Fahrenheit f f equals 9/5 C +

Rasek [7]

Use the given equation and solve for C.

F = 9C/5 + 32

F - 32 = 9C/5

5(F-32) = 9C

C = 5(F-32)/9
