Luke made a model that has 1 circular base and 1 curved surface.what solid figure did he make

Answers

The requried Luke made a cone, as it has one circular base and one curved surface that tapers to a point called the vertex.

What is a cone?

A cone is a three-dimensional geometric shape with one circular base and one curved surface that tapers to a point called the vertex. The base of the cone can be any size, and the curved surface can be formed by connecting all the points on the edge of the base to the vertex.

Here,
Luke made a cone. A cone is a solid figure with one circular base and one curved surface that narrows to a single point called the vertex. The base of the cone can be any size, and the curved surface can be formed by connecting all the points on the edge of the base to the vertex.

Thus, Luke made a cone, as it has one circular base and one curved surface that tapers to a point called the vertex.

if you have a curved surface and a circular base, you can put the base on top of the surface to make a cone

Product of a whole number and unit fraction for 3x3/4

Answers

Because all real numbers can be expressed as fractions, whole numbers can be too, with the denominator as 1.

e.g. 3 = 3/1

And then it works like normal multiplication

3/1 x 3/4 = (3 x 3) / (1 x 4)
= 9/4
= 2 and 1/4

Also for future reference, normally * (the asterix, shift + 8) is used to show multiplication on a computer, because "x" is normally used in algebra to mean something else.

I believe its 2 and 1/4

terrell has a water purifier for backpacking. it will purify 1 liter of water in 1 min. how long would it take terrell to purify enough water for 4 canteens that each hold 750 mL, and two that each hold 1.5 L

Answers

4 × 750 = 3 L so it will take 3 minutes for 4 canteens and
2 × 1.5 = 3 L it will also take 3 minutes
total it will take 6 minutes.

Answer:

It would take 6 minutes to purify enough water.

Step-by-step explanation:

Water purifier will purify 1 liter of water in 1 minute.

Terrell needs enough water for 4 canteens that each hold 750 ml.

Water for 4 canteens = 750 ml × 4 = 3000 ml = 3 liters

water for 2 canteens = 1.5 L × 2 = 3 liters

Water for total canteens = 3 + 3 = 6 liters.

Now it is given that water purifier will purify 1 liter of water in 1 minutes so 6 liters of water will purify in 6 minutes.

A 30-minute TV program consists of three commercials, each 2 1/2 minutes long, and four equal-length entertainment segments. How long is each entertainment segment? What is the strategy plans and answer.

Answers

The length of each segment can be determine by subtract the length of three commercial.

The length of each segment is 5 minute 37.5 seconds.

Given:

Duration of TV program is 30 minute.

Duration of TV commercials is $2(1)/(2) \:\rm minutes$ .

Calculate the total length of three commercials.

$\begin{aligned}\rm {Total\: length}=(2(1)/(2))*3\n=2.5* 3\n=7.5\n\end$

Subtract 7.5 from total 30 min TV program.

$=30-7.5\n=22.5$

Now calculate the equal length of entertainment segments.

$\begin{aligned} \rm {Equal\: Length}=(22.5)/(4)\n= 5.625 \:\rm min\n\n=5 \:\rm min\:\rm and\: 37.5\: second\end$

Thus, the length of each segment is 5 minute 37.5 seconds.
