Answer:

2.23

Step-by-step explanation:

0.48 for the first ounce, and then 0.20 for the rest.

0.48 + (0.20 x 3) = 1.08

.95 ounces? We round that to 1.00 ounces.

1.08 + 1 = 2.08 BUT

<em>It's .95, isn't it? We need to do another part. </em>

.95 divided by 0.20 (the ounces by the cost) = 4.75

You need to convert the 4.75 to a fraction, so 4.75 becomes 4 3/4.

subtract the missing amount (to make the fraction equal to 1) from the cost, so

1/4 of 0.20 is 0.5. Subtract 0.5 from 0.20 makes it 0.15.

<em>Finally, add the costs.</em>

2.08 + 0.15 = 2.23.

The function = 3describes the volume of a cube, , in cubic inches, whose length, width, and height each measure inches. Find the
kolezko [41]

The correct structure of the question is as follows:

The function f(x) = x^3 describes a cube's volume, f(x) in cubic inches, whose length, width, and height each measures x inches. If x is changing, find the (instantaneous) rate of change of the volume with respect to x at the moment when x = 3 inches.

Answer:

Step-by-step explanation:

Given that:

f(x) = x^3

Then;

V = x^3

The rate whereby V is changing with respect to time is can be determined by taking the differentiation of V

dV/dx = 3x^2

Now, at the moment when x = 3;

dV/dx = 3(3)^2

dV/dx = 3(9)

dV/dx = 27 cubic inch per inch

Suppose it is at the moment when x = 9

Then;

dV/dx = 3(9)^2

dV/dx = 3(81)

dV/dx = 243 cubic inch per inch

9. Mark is filling up crates with watermelons for the food drive. He has large watermelons that weigh 10 pounds each and smaller
abruzzese [7]
9. 10x + 5y is the equation for larger watermelons + smaller watermelons (you did not provide information about the medium watermelons, so we must assume given the options you miswrote one of them). We can hold NO MORE than 500 pounds, so 10x + 5y must be smaller than 500. The best answer is C assuming that "5y" represents your "Medium Watermelons"- because smaller watermelons are stated to be 5 and medium ones should therefore be between 5 and 10, the option provided by A wouldn't make since because 3 pounded watermelons are not "medium" in comparison to the "small ones" that are heavier/bigger. Your best option is C, 10x + 5y < 500, the exact answer technically would be 10x + 5y <= 500.

Tyler believes that an 8-sided die can be used to predict whether customers at his store will use a coupon when making their pur
Alik [6]
"1 indicating a coupon and all other outcomes indicating no coupon"
Probability is (number of successful outcomes) / (number of possible outcomes)

Theoretical Probability of rolling a 1: 1/8 

Experimental Probability of using coupons: 4/48  =  1/12

So, the experimental probability of a customer using a coupon (that is, 1/12) is smaller than the theoretical probability of rolling a 1 (that is, 1/8).
