In order to find each one, we need to divide 23.96/4 to find what each pound costs. After dividing, you get 5.99. Each pound costs 5.99. So for the first one just multiply 2x5.99 and get 11.98. And the second one shows 17.97 so we can just divide 17.97 by 5.99 and get 3. Just work off of that and you’ll get the rest! But the answer would turn out to be C because you add 5.99 to 23.96 and you get 29.95! Hope this helped

Answer:

Step-by-step explanation:

Since the weight is proportional to the cost, let's find the slope of the chart.

(x,y) corresponds to (weight, cost)

Pick 2 coordinate points with both the weight and cost.

(4, 23.96) (6, 35.94)

$m=\frac{y2-y1}{x2-x1}$

$\frac{35.94-23.96}{6-4}= 5.99$

One pound is 5.99 dollars.

So to fill in the chart, multiply 5.99 by the number of pounds.

y=5.99x

2 lbs | $11.98

3 lbs | $17.97

4 lbs | $23.96

5 lbs | $29.95

6 lbs | $35.94

With this information, C would be the correct answer.

Step-by-step explanation:

a) 24.7×52.3=1291.81

On rounding off to 3 significant digits we get

1290

$\sqrt{ {42}^{2} - {28}^{2} }$

$\sqrt{1764 -784 } = \sqrt{980}$

=31.304951

On rounding off to 5 significant figures we get

=31.305

$\sqrt[3]{78} = 4.27265$

On rounding off to 2 significant figures we get

=4.3

Hence required answers

a)1290

b)31.305

c)4.3

I hope it helped you

choose the best definition for domain. a. The inputs of a relation b. the outputs of relation c. the movement of a graph either

d1i1m1o1n [39]

Hi there!

I like to think of the domain and range as coordinates, so think of the domain as the x value, or the input, and the range as the y value, or the output.
So, b wouldn't work because of what I just explained.
C could be defined as slope.
And d won't work because this would be defined as a function.

So the only answer left would be a. the inputs of a relation (but just know that domain is also the input of a function)

I hope I helped!

Mr. Stein is purchasing a 2.25 pounds of meat that cost $2.80 per pound. How much will he receive if he pays the cashier $20.00

antoniya [11.8K]

He will receive $13.70.

You would have to multiply 2.25 by 2.80 to get 6.30, which is the total cost due. Subtract 6.30 from 20 to get your answer, 13.70, or the change Mr. Stein will receive.
