It takes me into 30 minutes to walk from home to school when walking at 5 km per hour What is her average cycling speed If it ta
GREYUIT [131]

Answer:

10 km/h

Step-by-step explanation:

I'm not really sure about this but no ones answering your question and I wanna help.

So basically to calculate the average speed you need to divide the distance travelled by time taken

But you do not have the distance traveled. But it is mentioned that it takes u 30 minutes to walk from home to school when walking at 5 km/h so to find the distance all you have to do is... 30 x 5 = 150 km

Now that we have the time and distance all we have to do is find the average speed.

Average Speed = distance ÷ time

So 150 ÷ 15 = 10 km/h

Find the volume in cubic meter (C.U.M) of each of the cuboid whose dimensions are :
Leno4ka [110]

The volume in cubic meter of the cuboid with the dimensions length = 12 m , breadth = 10m, height = 4.5 m is 540 m³

<h3 />

<h3>Volume of a cuboid:</h3>
  • v = lwh

where

l =- length

w = width

h = height

Therefore,

l = 12 m

w = 10 m

h = 4.5

v = 12 × 10 × 4.5

v = 120 × 4.5

v = 540 m³

What is the answer to this??
Firdavs [7]

Answer:

x=3

z=65

Step-by-step explanation:

6x+97 and 14x+73  are vertical angles which means they are equal

6x+97= 14x+73

Subtract 6x from each side

6x-6x+97= 14x-6x+73

97 = 8x +73

Subtract 73 from each side

97-73 = 8x+73-73

24 = 8x

Divide each side by 8

24/8 = 8x/8

3 = x

Now we need to find z

6x+97  and z are supplementary angles which means they add to 180

6x+97 +z = 180

6(3) +97 +z = 180

18+97+z=180

Combine like terms

115+z = 180

Subtract 115 from each side

115-115 +z=180-115

z = 65

Opal West has made a claim for an injury of a visiting ten-year-old who broke a toe in the family swimming
lozanna [386]

Answer:

C. $1,103.88

Step-by-step explanation:

The total cost is:

1785.42 × 1.06635 = 1903.88

There was no physical damage to the pool, only an accidental injury.  So Opal pays the $800 deductible, and the insurance pays the rest, which is:

1903.88 − 800 = 1103.88
