Answer:
10 for 8.49
Step-by-step explanation:
8.49 divided by 10 equals .849
5.40 divided by 6 equals .900
So, the dog eats 5 cups a day and 1 pound of dog food is 10.5 cups.
A 50 lb bag is<span> $22.50.
Since you're asking how much it would cost to feed it a day we need to find out how much 1 pound of food costs.
</span>22.50 / 50 = 0.45
So, it's 0.45 for 1 lb. But 1 lb is 10.5 cups, not 5.
0.45 / 5 = 0.09
So, I believe it would cost 0.09 each day to feed the dog.
Answer:
1.64×10⁷ km
Step-by-step explanation:
We know this is a triangle rectangle, so we apply the Pythagorean Theorem
QR=sqrt(PR²+PQ²)
Solving it, we will encounter in
sqrt(2.56×10¹⁴+1.296×10¹³)
to solve it, we need to bring the two numbers at the same power of ten, so we move 1.296 of one place to the left:
sqrt(2.56×10¹⁴+0.1296×10¹⁴)
we can now add the two numbers:
sqrt(2.6896×10¹⁴)
to solve this, we do the square root of 2.6896 and divide 14 by two (the index of the root is 2, so for roots' properties we can divide 14 by 2 - the index)
which gives us
1.64×10⁷
Answer:
the answer is B because 3(x-2) is the same as 3x -2
