Answer:
B) 8 and 24.
Step-by-step explanation:
Just by looking at the answer choices, since one number must be three times the other, we can determine that the correct answer is B.
Regardless, let's work this out mathematically. Let the first number be <em>a</em> and the second number be <em>b</em>.
Their difference is 16. Hence:
The first number is three times the second number. So:
Substitute:
Solve for <em>b</em>. Subtract:
And divide both sides by two:
So, the second number is 8.
And since the first number is three times the second, the first number is 24.
Our answer is B as expected.
Answer:
7 7/8
Step-by-step explanation:
It will be 3 weeks because if you divide 7/2,100 it will become to be 3weeks
Answer:
C. 540 in^3
Step-by-step explanation:
What you do is you use the formula V=lwh.
All your doing id=s multiplying them together.
V=18*10*3=540 in^3.
We are given
Firstly, we will simplify left side
and we will check whether it is equal to right side
Left side:
Let's assume y left side expression
now, we can take cos on both sides
we can simplify it
Right side:
Let's assume y left side expression
Multiply both sides by -1
now, we can take cos on both sides
we can simplify it
we can see that
both sides cos(y) value is different
so, this is FALSE.........Answer
