Answer:
Final alloy
- weighs grams
- contains grams of cooper
- percent of cooper in alloy is
Step-by-step explanation:
Suppose that a certain alloy is made by mixing 90 grams of an alloy containing 50% of copper with 70 grams of an alloy containing 35% copper.
50% alloy contains
grams of cooper
35% alloy contains
grams of cooper
Final alloy
- weight grams
- contains cooper grams
- percent of cooper in alloy
Answer:
243 outcomes
Step-by-step explanation:
Number of fruits = 5
Number of bowls = 3
Number of ways to put the fruits in the bowls = ?
Consider the number of choices for each fruit.
There are three bowls where you can place that fruit. So for all five fruits, there are a total of:
3^5 = 3*3*3*3*3
#9
7 / 1
-------
1 / 3
= 7 x 3
-----------
1 x 1
= 21
------
1
21 miles per gallon
# 11
2/3 / 1/4
= 2/3 * 4/1
=8/3
Hello,
The rate of change is the slope (rise/run, y/x). To find that, we use the equation (y2-y1) over (x2-x1). It means take the second "y" and subtract it from the first "y" and the same to "x". If I plug in the numbers, it would be (3-6) over (5-4), and after you subtract, the answer simplifies to: -3/ 1 which is -3. Yay! We got the slope (rate of change) done.
Now let's find the y-intercept by using the formula of point-slope form,
y-y1= m (slope) (x-x1). This is saying you "y" is subtracted from the first
"y" of the points which equals the slope (m) times the quantity of "x" subtracted by the first "x" of the points.
Let's plug the numbers in: y-6 = -3 (x-4). Let's distribute -3 to the parenthesis, and after that it should simplify to: y-6 = -3x + 12. To get "y" by itself, add 6 to both sides: y = -3x +18. We have finally found the slope-intercept equation for those two points (4,6) and (5,3). To then find the y-intercept in this equation, it would be the 18, because -3 is the slope, so that makes 18 the y-intercept.
In conclusion, the rate of change is -3 and the y-intercept is 18.
I hope this helps!

You would need 6 quarts of milk. You would do 24(2) then you take 48 and divide it by 288 and you get 6.
