Answer:
- <u>Two equivalent fractions with whole numbers may be 180/150, or 6/5</u>
- <u>The height of the tree is 39.6 feet.</u>
Explanation:
The diagram provides the proportion of the heights to the shadows:
From that you are asked (i) to simplify the fraction of the right side to one with whole numbers.
You can do that in two steps by multiplying both numerator and denominator by 10:
You can simplify that fraction if you divide by the greatest common factor of 180 and 150, which is 30:
The second part (ii) asks to find the height of the tree, that is x. To solve for x you can multiply both sides by the denominator of the fraction on the left and then simplify:
Thus, the height of the three is 39.6 feet.
Answer:
$46000
Step-by-step explanation:
if x represents the previous years revenue, and they made 35% more than x, we need to find what 35% of x is and then add it to x to get the new total, so the equation becomes:
x + .35x = 62100
1.35x = 62100
x = 46000
Answer:
no.
Step-by-step explanation:
The sum of two side lengths have to be <u><em>greater</em></u> than the value of the remaining side length.
Hope this helps. Have a nice day you amazing bean child.
Answer:
8 m/s^2
Step-by-step explanation:
You can use the equation a = v^2 / r
That is acceleration is equal to velocity squared divided by the radius which in this problem is the length of the string. The velocity is 4m/s and the r the radius is 2 m. Now you can square 4 m/s to get 16 m^2/s^2 THEN you divide by 2 m and the m^2 turns to just m and the 16 to an 8. So, that leaves you with acceleration or in this case centripetal acceleration equals 8 m/s^2.
a = 8 m/s^2 or 8 meters per second squared.
