P=2l +2w to find w use Pythagorean theorem
25^2 -24^2= w^2
625-576=w^2
w=7
2l +2w: l=24 w=7
24+24+7+7=62
Perimeter=62 cm
Answer:
228m
Step-by-step explanation:
Let's draw a rectangle ABCD, A being its bottom left point, B bottom right, C top right and D top left.
That is our soccer field. The player stands in the southeast corner, which is top right corner or, in our case point B. He passes the ball to the player in the opposite corner, which is corner D. He then passes the ball to the player in the southwest corner, which is corner A. And he finally passes it back to the player in the corner B.
So, the ball goes from B to D to A to B. That means that the ball went along the circumference of the triangle DAB.
So, to answer how long the ball travelled we need to find the circumference of the triangle. The circumference is the sum of its three sides. One side is the field's length (76m) and the othet is field's width (57m). We only need to find the triangle's hypotenuse, side BD, using Pythagoras theorem:
BD² = AB² + AD²
BD² = 76² + 57²
BD = 95
So, the circumference of the triangle is 76+57+95=228m
Answer:
2/10 = 1/5
Step-by-step explanation:
To figure out the probability of something, we can take
(number of outcomes of that something) / (number of total outcomes)
Here, we are trying to find the probability that the ball is white. The number of outcomes that are possible with the ball being white is 2, as there are two white balls and you can only pick one. You can pick either of the two white balls, but there is no way to pick one of them two times, pick two of them at once, or pick any other ball and have it be white.
The number of total outcomes is 10. There are 10 balls, and you can only pick one ball at a time. There are only 10 options to choose from.
Therefore, we can plug our numbers into the formula above and get 2/10 = 1/5 as our probability

Answer:
254.8
Step-by-step explanation:
Substitute the numbers where the variables are and do the arithmetic.
4c +2b³ = 4(1.2) +2(5³) = 4.8 +250 = 254.8
