Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given the following expression:

You need to substitute the given values of "a" and "b" into the expression. Notice that these values are:

Then;

Now you must solve the multiplications:

The final step is to add the numbers. Therefore, you get the following answer:

Answer:
21/20
Step-by-step explanation:
a) One hour is equivalent to 60 minutes.
So we can multiply 50 minutes by the fraction
, so we could convert 50 minutes to hours.
It is:

If we simplify the fraction, we have:

b) In order to express the turtle's speed in miles per hour, we have to divide
by 
So:

We simplify the expression by multiplying 7 mile by 6 and 8 by 5 hours:

The given function is:
P = 0.04x + 0.05y + 0.06(16-x-y)
To get the function at each vertex, all you have to do is substitute with the given x and y values in the above equation and get the corresponding value of P as follows:
1- For (8,1):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(8) + 0.05(1) + 0.06(16-8-1)
P = 0.79
2- For (14,1):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(14) + 0.05(1) + 0.06(16-14-1)
P = 0.67
3- For (3,6):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(3) + 0.05(6) + 0.06(16-3-6)
P = 0.84
4- For (5,10):
P = 0.04x + 0.05y + 0.06(16-x-y)
P = 0.04(5) + 0.05(10) + 0.06(16-5-10)
P = 0.76
Hope this helps :)
Answer:
Option A , C and D are correct.
Step-by-step explanation:
Double Facts states that the additions in which a number is added to itself.
then; by definition of double facts
Use Double facts to find the sum of 3 + 2
3 + 2
=3 + (3 - 1)
= 3+ 3 - 1
= 6 - 1
= 5
similarly,
3+2 = (1+2) + 2 = 1 + 2+2 = 1 + 4 = 5
Also;
3 + 2 = 3 + (1+1) = 3 +1+1 = 5
therefore, the double facts that used to find the sum of 3+2 are; 2+2 , 3+3 and 1+ 1.
