The rule for a pattern is ''take half the number to get the next number.'' the first number in the pattern is 16 what is the next number?

Answers

Answer:

8

Step-by-step explanation:

Let the next number be x

'taking half the number to get the next number. is expressed as;

1/2 of 16 = x

x = 1/2 *16

x = 16/2

x = 8

hence the next number will be 8

Hello! answer: 39

Step-by-step explanation:

Formula for triangles area: base × height ÷ 2

Formula for squares area: base × height

5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39

Answer:

39

Step-by-step explanation:

5x3=15

15/2=7.5

7.5x4=30

Trisha's favourite song is 2 1/2 minutes. There is a drum solo that begins one third of the way into the song and last for 24 seconds. How many seconds does the drum solo end

Answers

Answer:

74 seconds or1 minute 14 seconds

Step-by-step explanation:

The drum solo begins a third of the way into the song which lasts 2.5 minutes.

The drum solo therefore starts at:

= 2.5 * 1/3

= 0.83 minutes

Translate that to seconds by multiplying by 60:

= 0.83 * 60

= 50 seconds

Solo begins at 50 seconds in and lasts for 24 seconds:

= 50 + 24

= 74 seconds or

= 1 minute 14 seconds

Cecil measures the length and width of a playground. What is the most appropriate unit of measure for the dimensions of the playground?

Answers

Answer:

Meters

Step-by-step explanation:

Meter is the standard unit of length in SI system and is normally used to measure houses and fields, therefore it is appropriate unit of measure for the dimensions of the playground.

A meter has 100 centimeters which is fairly small unit and cannot be used for dimensions of playground.

Similarly a Kilometer has 1000 meters and is used to measure long distances from one place to other which also makes it inappropriate unit for dimension of playground.

Lincoln technical college has 156 students they expect 700 guest for a special speaker the custodian has set up 1500 chairs how many more chairs are needed if everyone is do you have a seat

Answers

Answer: 56 seats

Step-by-step explanation:

Question should say 856 students not 156 students.

If there are 856 students and 700 guests, the total number of people coming for the event is:

= 856 + 700

= 1,556 people

There are 1,500 seats so the extra seats needed are:

=Number of people coming - Seats available

= 1,556 - 1,500

= 56 seats

If the question is indeed 156 students then there is no need for extra seats as the total number of people coming would be: 156 + 700 = 856. Seats would be surplus.

Isaac has a points card for a movie theater.
He receives 65 rewards points just for signing up.
He earns 12.5 points for each visit to the movie theater.
He needs at least 210 points for a free movie ticket.
.
PLEASE HELP

Answers

if you are asking how many visits isaac would have to make to the movie theater then the answer would be 12

how i got this:

i subtracted 65 from 210 to eliminate the reward points given when signing up because those points were not earned for the amount of times he visited the theater

after doing so, i got 145. from there i divided 145 by 12.5 to determine the amount of visits he would have to make

that gave me 11.6, however i rounded up to 12 because if he only visited the theater 11 times he would only have 137.5 points. thus, if isaac visited the theater 12 times he would have a total of 150 points. (having enough for the free ticket)

Answers

Answer:

D.

Step-by-step explanation:

The volume can be found by adding the volumes of a cylinder (the upper part of the figure) and a cone (the lower part of the figure).

Volume of Cylinder:  [tex]V=\pi r^2 h=\pi(3^2)(3)=27\pi\approx 84.823 \text{ cubic feet}[/tex]

Volume of Cone:  The height of the cone is 3 feet (the whole figure is 6 feet tall and the cylinder uses up 3 feet of that -- 6 - 3 = 3).

[tex]V=\frac{1}{3}\pi r^2 h=\frac{1}{3}\pi(3^2)(3)=9\pi\approx 28.274[/tex]

The total volume is 84.823 + 28.274, about 113.1 cubic feet

A cubical container is 3/4 filled with water. It contains 4.374l of water. Find the base area of the container.

Answers

Answer:

The base area is 3.24 dm^3

Step-by-step explanation:

Let the total volume of the cube be x l

3/4 of this is 4.374 l

Thus, we have it that;

3/4 * x = 4.374

3x = 4 * 4.374

x = (4 * 4.374)/3

x = 5.832 L

The volume of a cube is the length of its side raised to the power of 3

Let us have the length as y

so;

y^3 = 5.832

y = cube root of 5.832

y = 1.8 dm

The area of the base is simply the side length raised to the power of 2

we have this as:

1.8 * 1.8 = 3.24 dm^2
