A prism with a square base has a height of 15cm and a volume of 735cm3. Find the length of each edge of the base.

denis-greek [22]

Answer:

The length of each edge of the base is 7cm.

Step-by-step explanation:

The volume of a prism with square base is given by:

$V = l^{2}h$

In which l is the length of each edge of the base and h is the height.

A prism with a square base has a height of 15cm and a volume of 735cm3.

This means that $V = 735, h = 15$

$V = l^{2}h$

$735 = 15l^{2}$

$l^{2} = \frac{735}{15}$

$l^{2} = 49$

$l = \pm \sqrt{49}$

Length is a positive measure. So

$l = 7$

Volume in cm³, so the length of each edge is in cm.

The length of each edge of the base is 7cm.

A trinket factory can produce 3,000 trinkets per day. The warehouse has a capacity of 50,000 trinkets. Currently, there are 8,00

Ugo [173]

An equation for the number of trinkets in the warehouse after x days:
8,000 + 3,000x = 50,000

How many days will it take to fill the warehouse?

8,000 + 3,000x = 50,000
3,000x = 42,000
x = 14

Elena L [17]

Answer:

Step-by-step explanation:

let the number=x

8(x-2)=16(x-5)

divide by 8

x-2=2(x-5)

x-2=2x-10

2x-x=-2+10

x=8

The expression 12g gives the number of kilometers a car can travel using g liters of gasoline. How far can this car travel on 5

makvit [3.9K]

Answer:

66 km

Step-by-step explanation:

Given that

Number of km's traveled by a car using g liters of gasoline = 12g

Number of gallons of gas required to travel 12g kilometers = g

We have to find

How far this car can travel using $5 \frac{1}{2}$ or 5.5 liters of gasoline = x= ?

Now we can find this by substituting g= $5 \frac{1}{2}$ in the the above equation representing number of kilometers traveled by the car.

Number of km's traveled by a car using $5 \frac{1}{2}$ liters of gasoline = 12 ( $5 \frac{1}{2}$ )

x = 12 (5.5)

x= 66 km

So, the car travels 66km in 5.5 liters of gasoline
