Sheila can ride her bicycle 6000 meters in 15 minutes. How far can she ride in 2 minutes?

7 0

Sheila can ride her bicycle 6000 meters in 15 minutes.
Forming that into a ratio, that will be 6000 : 15

Doing the proportion for 2 minutes.
6000 : 15 = X : 2

Doing the computation.
6000 / 15 = X / 2
15X = 2 * 6000
15X = 12000
X = 800

So Sheila covered a total of 800 meters in 2 minutes.

Answer:

use a calculator itl be easy

Step-by-step explanation:

substitute x to 150

=0.00125(x)^4+x-3

=0.00125(150)^4+150-3

WE ARE USING PEDMAS HERE SO BE CARE-FULL parenthesis,exponent,multiplication,division,addition,subtraction

=0.00125(506250000)+150-3

=632812.50+150-3

=632962.50-3

=632959.50

I AM SO SORRY IF IT IS WRONG :)

If AOB = 70° and OC is the bisector of AOB then what is the measure of AOC?

Sonja [21]

<h3>Answer: 35°</h3>

Reason: The angle bisector cuts the original angle (70°) in half to get 70/2 = 35.

PLEASE PLEASE HELP WITH THIS

Since triangles ABC and BCD are similar, we can establish a proportion between the lengths of corresponding sides:
$\frac{AC}{BC} = \frac{BC}{CD}$

We can infer from our picture that $BC=m$ . Also we can find the length of AC by adding AD and CD:
$AC=AD+CD$
$AC=11+7$
$AC=18$

Lets replace the values in our proportion:
$\frac{AC}{BC} = \frac{BC}{CD}$
$\frac{18}{m} = \frac{m}{7}$
Solving for $m$ :
$m^2=(18)(7)$
$m^2=126$
$m= \sqrt{126}$

We can conclude that the correct answer is: D $\sqrt{126}$
