Answer:
210 cm^3
Step-by-step explanation:
To find the volume of a regular we use the following formula:
l*w*h (l: length, w: width, h: height)
6*5*7 = 210 the volume is expressed with cm^3 so the answer is 210 cm^3

For converting units of area, it is necessary to know the conversion factors and relate the units. For the units of area, each unit is 100 times larger than the previous. See below the relationship between the meter and the other units
1km²=1 000 000 m²=[tex]10^6[/tex] m²
1 hm²= 10 000 m²= [tex]10^4[/tex] m²
1 dam²=100 m²= 10² m²
1 m² =1 m²= 1 m²
1 dm²=0.01 m²= [tex]10^{-2}[/tex] m²
1 mm²=0.000001 m²= [tex]10^{-6}[/tex] m²
Now, you have the necessary information for converting the units.

A money box contains only 10-cent and 20-cent coins. There are 40 coins with a total value of $6.50. How many coins of each?
Answers
Answer:
10x+20y= 350
Step-by-step explanation:
Add the decimal. 3.50
Let's assume that all the coins are 10-cent coins.
The total value would be 10 x 40 = 400 cents = $4
So, it would be $2.5 less than the actual total value,
We now know that not all the coins are 10-cent coins, so now we will replace 1 10-cent coins with a 20-cent coins.
Everytime we switch a 1 10-cent coins to a 20-cent coins, the value go up 10 cents. So, we need to switch 25 times (to make the value goes up $2.5)
-> There are 25 20-cent coins and 15 10-cent coins
Recheck : 25 x 20 + 15 x 10 = 500 + 15 = 650 cents = $6.5

The Kingda Ka roller coaster at Six Flags NJ is the tallest steel roller coaster. The car has a mass of 9750 kg with passengers. It is shot across a horizontal track then climbs up a vertical incline to a height of 139 m before stopping at the top. Ignoring friction and air resistance, what amount of kinetic energy must the coaster have before it goes up the incline?
Gravity 9.8 m/ ^2s
physical science!
Help pls
Answers
The kinetic energy that the coaster must have before it goes up is: 13.3megajoules.
What is kinetic energy?Kinetic energy refers to the energy that a body possesses due to its motion. It's known to be the energy needed to move a body of a given mass from rest to its stated velocity.
We can calculate the kinetic energy of the Kingda Ka roller in the following way:
K.E = Potential Energy
K.E = mgh
Where: m = mass = 9750
g = acceleration due to gravity = 9.8m/s²
h = height = 139m
Thus: K.E = 9750 x 139 x 9.8 = 13,281,450J
= 13.3megajoules.

b 2250 cm 2
c 165 cm2
d 4500 cm2
Answers
Answer:
Below in bold.
Step-by-step explanation:
The area of each triangle = 1/2 * height * base
