expeople1 [14]

Answer: 1852.5 cubic inches

Step-by-step explanation:

The Volume of cuboidal box is given by:-

$Volume=length\times width\times\ height$

Given: The length of box = $9\frac{1}{2}\ inches=\frac{19}{2}\ inches$

The width of the box = $15\ inches$

The height of the box = $13\ inches$

Now, the volume of box is given by:-

$Volume=\frac{19}{2}\times15\times13=\frac{3705}{2}=1852.5\ inches^3$

2x+ 4x = 6x

9x - 6x = 3x

Noah is correct as the - sign tells us that you have to subtract everything after the 9x

Hope this is ok and helps a little bit

A car manufacturer builds trucks and cars both in red, blue, and green colors. Let B represent the set of all red vehicles produ

telo118 [61]

Answer:

Step-by-step explanation:

The universal set, U is a set of all vehicles produced by the manufacturer.

U = red, blue and green vehicles(both cars and trucks)

B = all red vehicles produced by the manufacturer(both cars and trucks)

C = red, blue and green trucks

C ' = all elements that are not in C but are in the universal set

C ' = red, blue and green cars

B intersection C ' = all elements that are common to set B and set C '. Therefore,

B intersection C ' = red cars

Vesna [10]

Answer: Option B) 7,214

Step-by-step explanation:

The value of the digit 2 in 5,426 is 20.

-In 2,843, the place value of 2 is 2000

- In 7,214, the place value of 2 is 200

- In 43,928, the place value of 2 is 20

- In 67,452, the place value of 2 is 2

So, since he place value of 2 in 7,214 is 200; and since 200 is ten times more than 20 (i.e 20 x 10 = 200)

Thus, the answer is 7214

The weight of an object on mars varies directly is proportional as the weight of the object on earth a 75 pound object on earth

dedylja [7]

Answer:

It weighs 40 pounds on mars

Step-by-step explanation:

Direct proportion is the relationship between two variables when their ratio is equal to a constant value

It can be expressed as y = k x, where y varies directly as x and k is constant of variation
It can be expressed as $\frac{y_{1}}{x_{1}}=\frac{y_{2}}{x_{2}}=k$

∵ The weight of an object on mars varies directly as the weight

of the object on earth

∴ w(m) = k × w(e)

∵ The weight of the object on earth is 75 pound

∴ w(e) = 75

∵ The weight of this object on mars is 25 pounds

∴ w(m) = 25

- Substitute them in the equation of variation

∵ 25 = k × 75

- Divide both sides by 75

∴ $\frac{1}{3}$ = k

∴ w(m) = $\frac{1}{3}$ × w(e)

∵ An object weighs 120 pounds on earth

∴ w(e) = 120

- Substitute it in the equation of variation

∴ w(m) = $\frac{1}{3}$ × 120

∴ w(m) = 40

∴ It weighs 40 pounds on mars
