So first you find 10% which is 34.5

If tomatoes are $3.22 per pound and Nico spends $5.76 on tomatoes, how many pounds did he purchase?

juin [17]

In order to find out the amount of pounds of tomatoes purchased:

We have to know how much one pound is ($3.22 per pound)

Total Nico spent ÷ Price per pound

So it would be

5.76 ÷ 3.22 = 1.78881987578

Rounding our decimal number:

If we round to our nearest tenths it would now be 1.8

Answer:

Therefore, the total number of pounds Nico purchased for $5.76 is 1.8lb.

A box has 1 red marble, 3 blue marbles, and 4 green marbles. Maya draws a blue marble randomly from the box, replaces it, and th

allochka39001 [22]

Answer:

$\dfrac{9}{64}$

Step-by-step explanation:

Sampling with replacement means that we choose a marble, note its colour, put it back and shake the box, then choose a marble again.

There are $1+3+4=8$ marbles in total. The probability that the first chosen marble is blue is $\dfrac{3}{8}.$ then Maya replaces this marble and the probability of choosing the second blue marble is the same. Using the product rule, the probability of drawing 2 blue marbles in a row is

$\dfrac{3}{8}\cdot \dfrac{3}{8}=\dfrac{9}{64}.$

Help please................

The answer is yes she incorrectly graphed using the points (-2,4) instead of the point (4,-2). This is the answer because if you solve the equation given you should get y=-3/5x+2/5 so a and e will be wrong and if you plug one of the points in you will give a untrue statement so its not d so you are left with b and c so you plug in the end request and you get a true statement with b equaling -2 if you plug in 4 in for x
