Speed = distance divided by time. Plug in what you know.
Speed = 51.2 km / 4 hrs. ****** Simplify *******************
Speed = 12.8 km/hr
In order to write the given number in Scientific Notation we have to move the decimal digit 10 places to the right.
Moving decimal to the right means, the exponent of 10 will be negative when the number is written in scientific notation.
Since, we have to move the decimal by 10 digits, the exponent of 10 will be -10.
Therefore, the number written in scientific notation will be:
<span>Total cost of cashews + Total cost of peanuts = Total cost.
total cost of cashews=$7 * x=7x
total cost of peanuts=$3 * 9=27
total cost=(9+x) * $5=45+5x
7x+27=5x+45
subtract 5x from both sides:
2x+27=45
subtract 27 from both sides:
2x=18
x=9 pounds of cashews</span>
Answer:
The answer for that would be obtuse triangle
The volume of scaled object is 0.039375 cubic inches
<em><u>Solution:</u></em>
Given that,
Volume of box = 39.375 cubic inches
Scaled down by a factor =
The volume of a scaled object will be equal to the volume of object times scale factor cubed
Therefore,
Volume of scaled object = Volume of box x scale factor cubed
Thus volume of scaled object is 0.039375 cubic inches
