Answer:
surely it's 200 marbles bc 2/4 is equal to 1/2 and if u then half 400 you get 200
Step-by-step explanation:
Answer:
Step-by-step explanation:
Since the length of both legs of the right angle triangle are given, we would determine the hypotenuse, h by applying Pythagoras theorem which is expressed as
Hypotenuse² = one leg² + other leg²
Therefore,
h² = (3a)³ + (4a)³
h² = 27a³ + 64a³
h² = 91a³
Taking square root of both sides,
h = √91a³
The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
a, b and c are the side length of the triangle. Therefore, the expression for the perimeter of the right angle triangle is
√91a³ + (3a)³ + (4a)³
= √91a³ + 91a³
Answer: (a) The rate that the point 8,28 represents is 3.5 cm/s since 28/8 = 3.5
(b) The unit rate is 3.5 cm/s since the rate is constant.
(c) The two points lie on the same line and that both points results to a rate of 3.5 cm/s.

Answer:
The value of f(2) would be -40.
Step-by-step explanation:
Given function is,
Substituting x = 2 in the above function,
We get,
Hence, the value of f(2) would be -40.
Answer:
The probability is 5/36
Step-by-step explanation:
The total number of marbles is 2 + 4 + 1 + 5 = 12 marbles
The probability of randomly drawing a green marble would be
number of green marble/total number of marbles = 4/12 = 1/3
Now since we are replacing the total number of marbles stays the same
so, the probability of drawing a yellow marble now will be ;
number of yellow marbles/total number of marbles = 5/12
So the total probability we are having here would be; 1/3 * 5/12 = 5/36
