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 rhombus QRST is made of two congruent isosceles triangles. Given m∠QTS = 64, what is the measure of ∠Q?

Lubov Fominskaja [6]

Answer:

The measure of Q is 116

Step-by-step explanation:

For a Rhombus, opposite angles are equal

so angle R is 64 too

Now, we should understand that the diagonals bisect the angles

So the angles in the triangle QTR are

Q + 32 + 32 = 180

Q = 180-64

Q = 116 degrees

0.40 ___0.04 Please answer only if you are 100 percent sure a c =

natulia [17]

Step-by-step explanation:

0.40 ___0.04

We are given with two decimal numbers. Compare the numbers and complete the blank by < or > or =

To compare the decimals , compare each digit from left to right

0 is equal to 0

4 is greater than 0

so we can say 0.40 is greater than 0.04

0.40 > 0.04

Both decimal numbers are not equal

Answer:

0.40 > 0.04

Max tossed a fair coin 3 times. What is the probability of getting heads in the first two trials and tails in the last trial?

Whitepunk [10]

When you toss a coin 3 times here is what can happen:
H=heads
T= Tails
HHH TTT
<u>HHT</u> TTH
HTH THT
HTT THH
Since 8 things can happen and only one of them is what you want, the probability is 1/8
Another way to think about it is each toss has 1/2 of coming up as you want it to.
Three tosses are 1/2 x 1/2 x 1/2 which is 1/8
