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.

Hope that clarifies the answer.

Answer:

[tex]sum \: = (x + 1) + (2x + 1) + (x + 7) + (3x + 4) \\ = 7x + 13 \\ median = ( \frac{sum}{2} + 1) \\ 16 = ( \frac{7x + 13}{2} + 1) \\ 7x + 13 = 14 \\ 7x = 1 \\ x = \frac{1}{7} [/tex]

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

Answer:

Radius: 5.75

circumference:36.13

area:103.87

There you go!!

Answer:

radius : 5.75

circumference: 36.14

area: 103.91

this is 90 60 30 formula for example

90 meet 2x

30 meet x

and

60 meet x√3

so 90 meet 5

30 meet 5/2=2.5

and 60 meet 2.5√3

so the answer is 2.5

Answer:

2.5

Step-by-step explanation:

[tex]\sin 30\degree = \frac{x}{5}\\\therefore x = 5\sin 30\degree\\\therefore x = 5 \times \frac{1}{2}\\\therefore x = 2.5[/tex]

Answer:

I think that it would be 100^(0.085)

Answer:

1/13

Step-by-step explanation:

Since there are 4 suits (Clubs, Spades, Diamonds, Hearts) in total, with 2 of them being black and 2 being white, that means that each subset has 26 cards. Of these, 2 of them are either kings or jacks, depending on which subset you look at. There are 2 black kings and 2 red jacks in a regular deck of cards. The probability starts as 4/52, which is simplified to 2/26 and is finalized as 1/13. Convert to a percentage if necessary.

Answer:

25 MPG

Step-by-step explanation:

400/16 = 25

The miles per gallon of 16 gallons of fuel to drive 400 miles will be 25. The correct option is B.

Average refers to the distance a vehicle travels per unit of gasoline when no other conditions are present. Additionally, it is expressed as kmpl or mpg (miles per gallon) (kilometer per litter).

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that a vehicle is running 400 miles by using 16 gallons of fuel. The average of the vehicle will be calculated as below:-

Average = Distance / Quantity of fuel

Average = 400 / 16

Average = 25 mpg

Therefore, the miles per gallon of 16 gallons of fuel to drive 400 miles will be 25. The correct option is B.

Answer:

7/32

Step-by-step explanation:

John and George together raked 7/8 of the yard. John raked 3/4 of that amount. What part of the yard did john rake?

Proportion of the yard Jake raked = 7/8 x 3/4 = 21/32

Portion of the yard Jake raked = 21/32 - 7/8 = 7/32

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.

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

Answer: c = 13.96 or [tex]\sqrt{194.6}[/tex]

Step-by-step explanation:

[tex]a^{2}+b^{2}=c^{2}[/tex]

a and b = side lengths

c = hypotenuse

[tex]8.6^{2}+11^{2}=c^{2}[/tex]

[tex]73.96 + 121=c^{2}[/tex]

[tex]194.96=c^{2}[/tex]

[tex]c = 13.9628 = 13.96[/tex]

Answer:

YZ = 13.96

m∡Z = 52°

m∡Y = 38°

Step-by-step explanation:

found YZ first by using Pythagorean Theorem:

11² + 8.6² = YZ²

YZ² = 194.56

YZ = √194.56

YZ = 13.96

Used Law of Sines to find m∡Z:

sin 90°/13.96 = sin Z/11

sin Z = 11/13.96

arcsin Z = 52°

180 - (90 + 52) = m∡Y

m∡Y = 38°
