To tell which cubic unit of measure that should be used:

⇒ we should examine the unit of the side lengths

First question (a):

a rectangular prism that is 4cm by 9 cm by 2cm

⇒ must use cm³ as cubic unit of measure

⇒ as all sides are centimeters

⇒Answer: cubic centimeters or cm³

Second question(b):

a rectangular prism that is 5m by 4m by 9m

⇒ must use m³ as cubic unit of measure

⇒ as all sides are meters

⇒Answer: cubic meters or m³

Third question(c):

a rectangular prism that gives only two side length: 10dm, 6dm

⇒must use dm³ as cubic unit of measure

⇒ as all of the sides given are in decimeter

⇒Answer: cubic decimeter or dm³

Fourth question(d):

a cube that gives only one side length: 56mm

⇒ must use mm³ as cubic unit of measure

⇒ as all the given sides with side lengths are in millimeters

⇒ Answer: cubic millimeters or mm³

Fifth question(e):

a rectangular prism with two side length: 1m, 10m

⇒ must use m³ as cubic unit of measure

⇒ as all given sides with side lengths are in meter

⇒Answer: cubic meter or m³

In general:

⇒ when faced with these problems

⇒ look to the unit of measure of the majority of the side lengths

⇒ look to the unit of measure that the problem wants for the answer

Hope that helps!

Answer:

Step-by-step explanation:

a. 4cm * 9cm * 2cm = 72 cm^3

b. 5m * 4m * 9m = 180 m^3

c. 10dm * 36 dm^2 (because the square could also be represented as 6cm * 6cm) =360 dm^3

d. (56mm)^3 = 175616 mm^3

e. 10 m * 1 m^2 (because of the square) = 10m^3

The regression equation y=0.5x+1.3 approximates the number of hours it takes to arrange a dinner event, y, given the number of p

Sphinxa [80]

It would be C.

For example, say 1 person comes. This would be x=1. Plugging this in gives you,

y=0.5 + 1.3

This shows that C is true since x is always going to be multiplied by 0.5.

1.3 would be the base amount of time it takes to arrange since if it the y-intercept.

Wendy goes to the gym every 4 days and swims every 6 days. If she went to the gym and swam today, in how many days will she do b

Mice21 [21]

In 12 days, Wendy will do the both again.

Step-by-step explanation:

Given,

Wendy goes to gym every 4 days

Wendy swims every 6 days

We will find the least common multiple of both the numbers in order to determine the number of days in which she will do both.

4 = 4,8,12,16,20,....

6 = 6,12,18,24,.....

Therefore;

The least common multiple of 4 and 6 is 12.

Thus,

In 12 days, Wendy will do the both again.

In a certain game, a player can solve easy or hard puzzles. A player earns 30 points for solving an easy puzzle and 60 points fo

Aleksandr-060686 [28]

Answer: Second option.

Step-by-step explanation:

Let be "e" the number of easy puzzles Tina solved and "h" the number of hard puzzles Tina solved.

Set up a system of equations:

$\left \{ {{e+h=50} \atop {30e+60h=1,950 }} \right.$

You can use the Eliminationn Method to solve this system of equations:

Multiply the first equation by -30.
Add the equations.
Solve for "h".

Therefore, through this proccedure, you get:

$\left \{ {-30e-30h=-1,500} \atop {30e+60h=1,950 }} \right.\\.........................\\30h=450\\\\h=\frac{450}{30} \\\\h=15$
