Answer:
37.68in
Step-by-step explanation:
circumference = 2πr
r= radius = diameter/2 = 12/2 =6 in
C= 2πr = 2 x 3.14 x 6= 37.68in
Substitution!
<span>y = 4x – 10...(1)
y = 2...(2)
You have y=2 here, substitute it in equation (1),
</span><span>y = 4x – 10
</span><span>2 = 4x – 10
</span>Add both sides by 10
12=4x
Divide both sides by 4
x=3
We have x=3, and y=2. ==> (x,y) = (3,2)
Answer:
Total Cost : y = 2.75 + m (1) , where m = cost of each item
Step-by-step explanation:
The cost of admission and 3 samples = $5.75
The cost of admission and 6 samples = $8.75.
Cost is represented by y ,
The number of Samples = x
Let the admission charge is each case = $ a.
⇒ Total Cost y = a + (Number of items tasted x Cost of each item)
So, according to the question:
<u>First Case:</u>
a + 3x = $ 5.75
<u>Second Case:</u>
a + 6x = $ 8.75
Solving the above system of equations, we get a = $ 2.75
And , if a = $2.75 then x = 1
Hence, the Total Cost y = 2.75 + m (1) , here m = cost of each item
So first we will add together the fractions. 3/4 is equal to 6/8, so we will add 6/8 to 7/8 and get 13/8, or 1 5/8. Then we can add together the whole numbers, 19 and 18, to get 37. Then add 37 + 1 5/8 and get 38 5/8. Lastly, we subtract that amount from 50 to get a finale number of 11 3/8. The pet store donated 11 3/8 pounds of cat food! Hope this helps!
