Answer 1

for the first question
1. ( 5cm / 2km ) = ( xcm / 5km )
5*5 = 2x
25 = 2x
12,5cm = x
2. similar to (1) but having x as the km and 2 as the cm
5x = 2*2
x = 0,8 km
3. 192:2 to find the ratio of 1 cm to multiply by the length of the map
96*8.125=780cm
4. the are is (base*length)/2
use the same logic of (3) to find the real length of base
5*96=480cm
so for the the area (480*780)/2= 187200cm^2

in a raffle 200 tickets are sold 78 children and 93 women buy one ticket each men buy the rest of the tickets. work out the probability that a man buys the winning ticket

Answers

Answer:

The probability that a man buys the winning ticket is 107/200

Step-by-step explanation:

78 men buy tickets, 93 women buy tickets. If the rest of the tickets are given to men, there are 200-93-78, or 29 tickets left, which go to men. 78 + 29 = 107 men who have tickets.

The probability that a man buys the winning ticket is

number of men with tickets / number of tickets, or

107 / 200.

The volume of a cuboid is 450cm3.
The length is 10cm and the width is 15cm.
Work out the height of the cuboid.

Answers

Answer:

3cm

Step-by-step explanation:

The formula for the volume of the cuboid is [tex]w*l*h=volume[/tex]

We already have the length, width, and volume, so we have to plug it in to the equation.

[tex]15*10*h=450[/tex] (Just a heads up in case you didn't know: the centimeters cubed is just part of the units, so you don't need to worry about it when plugging it in to the equation.)

To solve for h:

1. Multiply 15 and 10

[tex]150*h=450[/tex]

2. Divide both sides by 150

[tex]h = 450/150[/tex]

h = 3

This is in centimeters, so the final answer is 3cm.

The height of a cuboid with a volume of 450cm³ with a length of 10cm and width of 15cm is 3cm.

How to calculate volume?

The volume of a cuboid can be calculated using the following formula:

Volume = length × width × height

According to this question, the volume of a cuboid is 450cm³ and has a length of 10cm and the width is 15cm. The height is as follows:

450cm³ = 15cm × 10cm × h

450cm³ = 150²h

h = 450/150

h = 3

Therefore, the height of a cuboid with a volume of 450cm³ with a length of 10cm and width of 15cm is 3cm.

Find the volume of the composite solid shown in figure

Answers

Answer:

113.14cm^3

36π cm^3

Step-by-step explanation:

the composite solid is made up of a cylinder and a hemisphere

volume of solid = volume of cylinder + volume of hemisphere

volume of a cylinder = nr^2h

n = 22/7

(22/7) x (3^2) x 2 = 56.57 cm^3

or in terms of pi = 18π

volume of a hemisphere = (2/3) x (n) x (r^3)

n = 22/7

r = radius

(2/3) x (22/7) x (3^3) = 56.57 cm^3

or in terms of pi = 18π

volume of solid = 56.57 cm^3 x 2 = 113.14cm^3

or 18π x 2 = 36π cm^3

A person is standing on the equator of Earth (radius 3960 miles). What are his linear and angular speeds?

Answers

Answer:

Linear speed =ωr=2π/86400×3960=11π/120 miles/s.

Step-by-step explanation:

The linear speed and angular speed will be 1036.73 miles / hour and 0.26 radian / hour.

It is given that radius of equator of earth is 3960 miles.

We have to find the linear and angular speeds.

What do you mean by the linear speed ?

The linear speed of a point on the object is equal to the angular speed (ω) multiplied by the distance r.

As per the question ;

radius of equator of earth = 3960 miles

The linear speed will be ;

s = rθ / t

We know that ; at any point of equator would complete 360° or 2π radians revolutions every 24 hours.

So ;

s = (3960 miles × 2π) / 24 hour

s = 330π miles / hour

s ≅ 1036.73 miles / hour

And

The angular speed will be ;

ω = s / r

ω = 1036.73 / 3960 minutes

ω = 0.26 radian/hour

Thus , the linear speed and angular speed will be 1036.73 miles / hour and 0.26 radian / hour.
