A hot air balloon holds 2,200 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter. How many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram?

Answers

Answer 1

Answer:

392.7

To get the answer multiply Density * Volume

Mass = 0.1785 * 2200

Mass = 392.7

Answer 2

The mass of the helium with a density of 0.1785 kilograms per cubic meter and volume of 2,200 cubic meters  is 392.7 kg

What is density?

The density of a substance is its mass per unit volume. It can be represented mathematically as follows:

density = mass / volume

Therefore,

mass of the helium = ?

density of the helium = 0.1785  kilograms per cubic meter

volume of helium = 2,200 cubic meters

Therefore,

mass = density × volume

mass =  0.1785 × 2200

mass = 392.7 kg

Mariah has a spinner that has 10 equal sections, each containing a different number from 1 to 10. Mariah determines about how many times the spinner will land on a number that is greater than 7 in 250 spins, and her work is shown below.

P (number greater than 7) = StartFraction Number greater than 7 over Total number of sections EndFraction times number of spins = StartFraction 4 over 10 EndFraction (250) = 100.

What mistake did Mariah make, if any?
Mariah has the formula reversed; it should be the total number of sections over the numbers greater than 7.
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.
Mariah should multiply by the number of sections in the spinner rather than the total number of spins.
Mariah calculated the prediction correctly and did not make any mistakes.

The daily cost of renting a car is $25.00 plus $0.30 per mile driven. What is the cost of renting the car for one day and driving at 75 miles?

Answers

Answer: The cost of renting the car for one day and driving at 75 miles = $ 47.5 .

Step-by-step explanation:

GIven: Daily cost of renting car = $ 25.00 + $0.30 per mile driven

Let x = Total distance traveled ( in miles).

Then total cost of renting (in $)= 25+0.30x

For x= 75 miles

The  total cost of renting (in $)= 25+0.30(75)

=25+22.5

= $47.5

Hence, the cost of renting the car for one day and driving at 75 miles = $ 47.5

The points of intersection are at (3, 6) and (-1, -2).

Since both of these equations have y isolated, we can set them equal to each other:

2x=x²-3

We want all of the variables on one side, so subtract 2x:
2x-2x = x²-3-2x
0=x²-3-2x

Write the quadratic in standard form:
0=x²-2x-3

This is easily factorable, as there are factors of -3 that will sum to -2. -3(1)=-3 and -3+1=-2:
0=(x-3)(x+1)

Using the zero product property we know that either x-3=0 or x+1=0; therefore x=3 or x=-1.

Substituting this into the first equation (it is simpler):
y=2(3) = 6
y=2(-1)=-2

Therefore the coordinates are (3, 6) and (-1, -2).

Answer:

(x1, y1)=(-1, -2)

(x2, y2)=(3, 6)

Step-by-step explanation:

y=2x

y=x^2-3

Since both of the expressions 2x and x^2-3 are equal to y, set them equal to each other forming an equation in x

2x=x^2-3

solve the equation for x

x=-1

x=3

Substitute the given value of x into the equation y=2x

y=2 x (-1)

x=3      y=2 x 3

Solve the equation for y

y=-2

y=2 x 3      y=6

The possible solutions of the system are the ordered pairs (x, y)

(x1, y1)=(-1, -2)

(x2, y2)=(3, 6)

Check if the given ordered pairs are the solutions of the system of equations

-2=2x(-1)

-2=(-1)^2-3

6=2x3

6=3^2-3

Simplify the equalities

-2=-2

-2=-2

6=2x3

6=3^2-3

-2=-2

-2=-2

6=6

6=6

Since all of the equalites are true, the ordered pairs are the solution of the system

(x1, y1)=(-1, -2)

(x2, y2)=(3, 6)
