In 8 hours, every barber completed 24 haircuts which gave a product of 120. 24 divided by 8 is 3. The answer is 3 haircuts per hour.

You want to rent a limousine for a trip to the city. The limo costs $700 for the night and $0.15 per mile. You have $750 to spen

frez [133]

The first thing I would do is write an expression for the amount the limo will cost in terms of the number of miles you drive. In this scenario, the cost=.15(mile)+700.
Now is the question, should the limo cost more or less than $750 to stay on budget? The answer is you should spend less than $750. Thus, when writing the inequality, or .15m+700<750. However, you could spend exactly $750 so you inequality should really be .15m+700≤750. Now you just need to solve this for the number of miles you can drive.

First, subtract 700 from both sides and you are left with .15m≤50
Then divide both sides by .15 and you are left with m ≤ 333.33. Thus, the limo can only travel 333.33 miles.

7 3/4 × 3/4 = So u add 3×3=9
Then add 4×4=16 Give you 9/16
Then you add that 7 you left out with 9/16
But just the 9 not the 16
7 × 9 = 63 And your answer is 63/16

What is the volume of the pyramid?

s2008m [1.1K]

Answer:

$16\sqrt{3}$ $cm^{3}$

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo,

<em>A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2. </em>

<em>What is the volume of the pyramid?</em>

My answer:

As we know, The volume of a pyramid = $\frac{1}{3}$ base area × its height

Given:

Side lenght of the base is; $4\sqrt{3} cm$

=> The area of the base is $12\sqrt{3}$ $cm^{2}$

In Δ ACB measure of angle ACB is 90° and m∠ CAB is 30°

We use: $tan(30) = \frac{BC}{AC}$

<=> BC = $4\sqrt{3}*tan(30)$

= 4 cm

And BC is the height of the the pyramid

=> The volume of a pyramid = $\frac{1}{3}$ $12\sqrt{3}$ $cm^{2}$ * 4 cm

= $16\sqrt{3}$ $cm^{3}$

During your journey, you develop an abscessed tooth and have to visit the dentist. You are prescribed an antibiotic with a dosag

RideAnS [48]

Answer:

I should take 10.44 tablets in a day, approximately 10.5 tablets.

Step-by-step explanation:

In order to solve this problem we need to convert the weight from pounds to kilograms, to do that we need to divide it by 2.205.

$w = \frac{128}{2.205}\\w = 58.05 \text{ kg}$

Since I need to take 7.5 mg per kg of body weight, then in order to find the dosage we need to multiply the weight in kg by 7.5.

$\text{dosage} = 58*7.5 = 435 \text{ mg}$

Since I need to take it every six hours and there are 24 hours in a day, we will have to take 4 dosages in a day, therefore we need:

$\text{dosage(day)} = 435*6 = 2,610 \text{ mg}$

The antibiotic comes in 250 mg in tablets, therefore the number of tablets is:

$tablets = \frac{2610}{250} = 10.44$

I should take 10.44 tablets in a day, approximately 10.5 tablets.
