A human red blood cell is 7.5 micrometers in diameter.1 centimeter = 10,000 micrometers
What is the diameter in centimeters?

Answers

Answer 1
Answer: To solve this question, we do cross multiplication.

1 cm = 10,000 micrometers
7.5 micrometers.

? Cm = 7.5 micrometers X 1 centimetre/10000 micrometers.

? Cm = 0.00075 cm
So 7.5 micrometers = 0.00075 centimetres.

Answers

You need to separate the numbers from the variable.

1) -10n -8= -118
Add 8 to both sides which takes you to -110

-10n=-110
Divide by -10 on both sides

What is the radius of a circle with center (2,1) and containing point (0,1)

Answers

Answer:

The radius is 2 or The simplified radius is 4 ( if needed).

Step-by-step explanation:

- The equation of a circle is:

(x-h)^2+(y-k)^2=r^2 where the center is (h,k), the point as (x,y) and the radius r^2.

-Put both the center and the point onto that equation:

(0-2)^2+(1-1)^2=r^2

-Then, solve them up:

(0-2)^2+(1-1)^2 =r^2

(-2)^2+0=r^2

4 + 0=r^2

4 = r^2

√(4) =√(r^2)

2=r

One day a store sold 30 sweatshirts. White ones cost $11.95 and yellow ones cost$11.50. In all, $349.95 worth of sweatshirts were sold. How many of each color were sold?

Answers

With this, I would use a guess and check method.
Start by splitting them half.
$11.95x15 sweatshirts = $179.25
$11.50x15 sweatshirts = $172.50
Then you add the totals to see how close you are.
$197.25+$172.50=$351.75
That's a little high. so we'll shift the amount of sweatshirts.
$11.95x14 sweatshirts= $167.30
$11.50x16 sweatshirts= $184.00
And add the totals again.
$167.30+184.00= $351.30
Closer, but too high still, so we'll shift it more in the direction we're going.
$11.95x11 sweatshirts = $131.45
$11.50x 19 sweatshirts = $218.50
Once again, add the totals to check if it matches.
$131.45+$218.50= $349.95
Therefore, 11 white sweatshirts and 19 yellow sweatshirts were sold.
