Find the volume of a pyramid with a square base, where the side length of the base is
ValentinkaMS [17]

Answer:

<h2>1529.4 m³</h2>

Step-by-step explanation:

Volume of a pyramid can be found by using the formula

v =  \frac{1}{3}  \times a \times h \\

a is the area of the base

h is the height

Since the base is a square we have

v =  \frac{1}{3}  \times  {15.3}^{2}  \times 19.6 \\  = 78.03 \times 19.6 \\  = 1529.388

We have the final answer as

<h3>1529.4 m³</h3>

Hope this helps you

A robin can fly 10 miles per hour faster than a blue jay. It takes a robin 1 1/2 hours to fly 45 miles.
cricket20 [7]

Answer: 2\dfrac14\text{ hours}

Step-by-step explanation:

Given:  It takes a robin 1\dfrac12 hours to fly 45 miles.

1\dfrac12=\dfrac32

Speed of robin= \dfrac{distance}{time}=\dfrac{45}{\dfrac32}

\dfrac{45}{3}\times2= 15\times2= 30\text{ miles per hour}

A robin can fly 10 miles per hour faster than a blue jay. It

Speed of Blue jay = Speed of robin - 10 miles per hour

= 30 miles per hour - 10 miles per hour

= 20 miles per hour

Time taken to cover 45 miles = \dfrac{45}{20}=\dfrac{9}{4}=2\dfrac14\text{ hours}

Hence, it will take 2\dfrac14\text{ hours}  by a blue jay to fly that same distance.

Nathaniel is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additi
Luba_88 [7]

Answer: C(t)=0.2x + 8

Step-by-step explanation:

If we know that we have a charge per minute it would look like mx with m being the charge for every x (minutes being used). We also know that there is an initial charge that has to be added on, but it won't change after the charge is set so we can call this "i".

Your equation from what we already know is going to be mx + i =Total charge.

Now that we have an equation, we an plug in what we know to solve for our initial charge. We plug in 0.2 for 5 since that is the cost for minute along with 5 for x since that is the amount of minutes. We do not know the initial charge so leave that as i, and plug 9 in for Total charge.

Your new equation should look like 0.2(5) + i=9 where we can multiply .2 by 5 and get 1 and then subtract 1 from both sides. This leaves you with 8=Total charge.

Since the problem is asking for a function representing the total cost we know that it is now C(t) 0.2x +8
