Answer:
2 cans
Step-by-step explanation:
Calculate how many pounds he needs for one day:
3(0.5)=1.5 pounds for each day Alvin is gone ( 3 represents his dogs, .5 is each dog's food)
Convert into ounces:
1.5*16=24 ounces for one day
Question: If dog food is sold in 12 oz cans, how many will he need?
24/12=2 cans
Thus, he will need 2 cans
If I’m not mistaken, the answer is C.
First, find slope of point A and B using slope formula:
<u>y2-y1</u> = <u>7-0 </u>= <u>-7</u>
x2-x1 3-8 5
Next, use the point-slope formula to find the equation (pick either point A or B to substitute into this equation; the answer will be the same either way):
y-y1=m(x-x1)
y-7=<u>-7</u>(x-3) (I used point B here)
5
y=<u>-7x</u> +<u>56</u> so the y-intercept is <u>56</u>. Hurray! Part 1 down!

Now to answer part 2. Since AB ll CD, they have the same slope: <u>-7</u>
5
Therefore, you can use the handy point-slope equation to calculate the equation of line CD. (Remember you only need one of the points to use this equation if you already have the slope.) Since the only point given is D(5,5), we'll use that one:
</span>y-y1=m(x-x1)
y-5=<u>-7</u>(x-5)
<span> 5
</span>y=<u>-7x</u> + 12 Yay! That's the answer to part 2; the equation of line CD

If she rides her bike 18 km per hour
then it will take 4 hours to travel 72 km (72÷18)
the answer is 4
They have collected
cans until now. To equal 325, they need
cans more.
A.
Let C be the number needed to equate atleast 325.

B.
If we solve the inequality in part A, we can find minimum number of C to meet the goal of 325 cans.

<em>So they need minimum 101 to complete the target and more than that to surpass.</em>
ANSWER: 101 cans are needed to meet the goal and more than that to surpass the goal.
