10 razors......1 lasts for 1 week...so 10 would last for 10 weeks.
1 week = 7 days...so 10 weeks = 70 days.

6.30 / 70 = 0.09 per day (it would cost 9 cents per day)

Joey Chestnut is trying to break his own record for eating the most whole hot dogs in 101010 minutes. He needs to eat more than

anygoal [31]

Answer:

$9d+11\frac{1}{4}>72$

Step-by-step explanation:

We are supposed to write an inequality to determine the number of hot dogs per minute Joey must eat for the last 9 minutes to break his record.

Let d represent the number of hot dogs Joey eats per minute for the next 9 minutes.

We have been given that after 1 minute, Joey has eaten $11\frac{1}{4}$ hot dogs.

Hot dogs eaten in next 9 minutes would be 9 times d that is $9d$ .

Total hot dogs eaten by Joey would be hot dogs eaten in 1 minute plus next 9 minutes: $9d+11\frac{1}{4}$ .

Since to break the record Joey needs to eat more than 72 hot dogs. We can represent this information in an inequality as:

$9d+11\frac{1}{4}>72$

Therefore, our required inequality would be $9d+11\frac{1}{4}>72$ .

Use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following equation. y=x^2+x+6

serious [3.7K]

Answer:

<em>Vertex; ( - 1 / 2, 5 3/4 )</em>

Step-by-step explanation:

No need for a calculator, take a look at the procedure below;

The vertex of an up - down facing parabola of the form y = ax^2 + bx + c is x = -b / 2a;

The parabola params are given to be 1, 1, and 6, such that;

x = - 1 / 2 * 1,

x = - 1 / 2,

Now plug in this value of x into the quadratic function as to solve for y;

y = ( - 1 /2 )^2 - 1 /2 + 6,

y = 1 / 4 + 5 1 / 2,

y = 5 3/4

Thus the vertex has a minimum of ( - 1 / 2, 5 3/4 ),

<em>Vertex; ( - 1 / 2, 5 3/4 )</em>

The regular hexagonal prism tank is completely filled with water. The tank has a height of 5 ft and the area of its base is 22ft

love history [14]

Answer:

110 ft³ of water

Step-by-step explanation:

Use the prism volume formula, V = Bh, where B is the area of the base and h is the height.

Plug in the area of the base and height, and solve for V:

V = Bh

V = (22)(5)

V = 110

So, the volume is 110 ft³

There is 110 ft³ of water in the tank
