Answer:
30 girls 30:24
Step-by-step explanation:
You would do 24 divided by 4 and get 6. Then you would do 5 times 6 to get 30.
Hope this helps.
Answer:
if the order of the digit matters, we have:
options: 1, 2, 3, 4.
We want to select two digits.
First selection: we have 4 options
Second selection: we have 3 options (because we already selected one in the first selection)
The total number of elements in the sample space, or the total number of combinations, is equal to the product of the number of options in each selection, this is:
P = 4*3 = 12
Answer:
Step-by-step explanation:
f(2) = 2^3 - 4(2)^2 = 8 - 4(4) = 8 - 16 = -8
g(-8)= 4(-8) + 5 = -32 + 5 = -27
C is the answer
Answer: 3 out of 6
Step-by-step explanation:
The numbers she choses from are 1-6 therefore its out of 6
The prime numbers before six are two, three, and five.
therefore its 3/6 chance or 1/2 chance she picks a prime number.
Answer:
The length of the longest side is 68mm
Step-by-step explanation:
The perimeter of a triangle is equals to the sum of all its sides
P=a+b+c
The triangle is isosceles, so two of its sides are equal, have the same length.
So: a=b, then
P=2a+c=168mm
Moreover, we know that the base is 18mm more than each of the legs, this means: c=18mm+a, where we obtain that a=c-18mm.
So, the system of equations is solved, lets use the above result in Perimeter`s equation.
168mm=2*(c-18mm)+C
From here we have:
168mm=3c-36mm
We obtain the following result: c= 68mm, this the length of the longest side
