Which is a better deal and why? Giant: $19.50 for 2.75 pounds beef chuck OR
Sam’s Club: $35 for 5 pounds of beef chuck

Answers

Sams is a better deal. With Giants, buying the same amount as Sams costs more so it’s not as good a deal.

Price/weight will give you cost per pound. (19.50/2.75)=$7.09/lb. (35/5)=$7/lb. since sams has the lower cost per pound, it is the better deal. (Remember to make sure both rates have the same unit. $/lb and $/lb or $/kg and $/kg

30 Points! A soccer ball hit from the ground into the air and is modeled by the function
h(t)=-16t^2+48t+2 (see attachment)

Answers

Answer:

At t = 3/2

36 feet

Step-by-step explanation:

The soccer ball is modeled by the function:

[tex]h(t)=-16t^2+48t[/tex]

Where h(t) represents the height in feet of the ball over time t.

Note that this is a quadratic equation.

Part A)

Since this is a quadratic, the maximum height will be reached when the ball reaches its vertex.

So, we will find the x-coordinate of the vertex.

The vertex is given by:

[tex]\displaystyle \Big (-\frac{b}{2a} , h( -\frac{b}{2a} ) \Big)[/tex]

In this case, a = -16 and b = 48. Thus, the t-coordinate is:

[tex]\displaystyle t=-\frac{48}{2(-16)}=-\frac{48}{-32}=\frac{3}{2}[/tex]

The ball will reach is maximum height at t = 3/2.

Part B)

To find the maximum height, we can simply substitute the value back into the function and evaluated. Therefore:

[tex]\displaystyle\begin{aligned} h(\frac{3}{2})&=-16\Big(\frac{3}{2}\Big)^2+48\Big(\frac{3}{2}\Big)\\\\ &=-16\Big(\frac{9}{4}\Big)+24(3)\\ \\ &=-36+72\\\\ &= 36 \end{aligned}[/tex]

The maximum height of the ball is 36 feet.

Gethyn drinks 48 fluid ounces of water in one day. He needs to drink 8 cups in total. How many more cups does he need to drink?

A) 2 cups
B) 6 cups
C) 384 cups
D) 768 cups

Answers

Answer:A

Step-by-step explanation:1 cup is equal to 8 fluid ounces so 48/8=6 and since he needs to drink 8 cups of water the answer is 2 more.

The number of cups of water Gethyn need to drink more is 2 cups. Therefore, option A is the correct answer.

What is metric conversion?

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

Given that, Gethyn drinks 48 fluid ounces of water in one day.

We know that, 1 ounce = 0.125 cups

Here, 48 fluid ounces = 48×0.125

= 6 cups

Number of cups of fluid = 8-6

= 2 cups

Therefore, option A is the correct answer.

c. Write the inequality that is shown on the number line.

Answers

Answer:

-3< x ≤ 4

Step-by-step explanation:

There is an open circle at -3, so -3 is not included

There is a closed circle at 4, which means 4 is included

The line is between which means x is between

-3 is less than x which is less than or equal to 4

-3< x ≤ 4

This type of graph is called a segment.

To write the inequality, read the segment from left to right.

We would start with the endpoint on the left which is a -3,

our variable x would be in the middle, and we would finish

things off with the endpoint on the right, which is 4.

Since we have an open dot at -3, we use a less than

sign between the -3 and the x and since we have a closed at 4,

we use a less than or equal to sign between the x and 4.

When representing a segment by reading it from left to right,

you will only use less than or less than or equal to between the parts.

So the solution for the inequality is read {x: -3 < x ≤ 4}.
