Each liter of air has a mass of 1.80 grams. How many liters of air are contained in 2.5 x103 kg of air?
Answer:
kg = 1,000 grams
[2.5 x 10^3] x 1,000 =2.5 x 10^6 grams of air.
[2,5 x 10^6] / 1.8 =~ 1,388,889 Liters of air in 2.5 x 10^3 kg.
Step-by-step explanation:
There are 1.39 x 10⁶ liters of air contained in 2.5 x 10³ kg of air.
Given that 1 liter of air is 1.80 grams.
2.5 x 10³ kg = 2.5 x 10³ × 1000 grams (since 1 kg = 1000 grams)
Calculating the mass in grams:
2.5 x 10³ × 1000 grams = 2.5 x 10⁶ grams
Now, to find the number of liters of air, we divide the mass (in grams) by the mass of 1 liter of air:
Number of liters = Mass / Mass per liter
Number of liters = 2.5 x 10⁶ grams / 1.80 grams per liter
= 1.39 x 10⁶ liters
Therefore, there are approximately 1.39 x 10⁶ liters of air contained in 2.5 x 10³ kg of air.

A 2-axle passenger vehicle with a SunPass drives
through the Orlando (1-4) Mile Post five times.
Determine the total amount of money that will be
deducted from this vehicle's SunPass account.
The amount of money to be deducted from the vehicle's SunPass account is $2.65
To obtain the total toll fee charged; we take the product of the toll fee at the Orlando (1 - 4) mile post and the Number of times the car passes through the toll post.
The discounted toll fee at Orlando(1 - 4) mile post is $0.53
Number of times vehicle passes = 5
Hence, The total fee charged will be :
($0.53 × 5) = $2.65

Eva spent $48 on a shirt and a pair of pants. The pants cost twice as much as the shirt. How much did each item cost
Answer:
s=16, p = 32
s is shirt and p is pants.
s+p=48
since the cost of the shirt and the pants together is $48
p=2s
the cost of the pants was 2 times as much as the shirt.
substitute p in s+p=48
s+2s=48
3s=48
divide both sides by 3
s=16
The shirt costs 16.
now substitute 16 in for s in p=2s
p=2*16
p=32

Tegan needs to make 68 more snow blocks to finish
building an igloo.
Write an equation for the number of blocks Tegan still
needs to make, m, when she has completed c blocks.
legan completes 33 blocks.
How many blocks does Tegan still need to make to
finish the igloo?
blocks
Answer:
m = 68 - c
Step-by-step explanation:
It is given that Tegan needs to make 68 more snow blocks to finish building an igloo.
Let m be the number of blocks Tegan still needs to make and c be the number of completed blocks.
If total number of required block is 68 and c blocks are completed then the remaining blocks is the difference between 68 and c.
Number of blocks Tegan still needs to make = 68 - c
We know that c represent the number of blocks Tegan still needs to make.
m = 68 - c
Therefore, the required equation is m = 68 - c.

Round to the nearest hundredth.
The probability that a randomly selected bow tie is made of velvet gave that the bow tie is designed with swirls is 1/3
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given this, John keeps track of how many bow ties he has and organizes them by pattern and material.
Velvet Cotton
Zigzags 6 3
Swirls 3 3
There are a total of 9 bow ties with swirls, out of which 3 are made of velvet. So the probability of selecting a bow tie made of velvet, given that it has swirls, is:
P(Velvet | Swirls) = P(Velvet and Swirls) / P(Swirls)
P(Velvet and Swirls) is the number of bow ties that have both velvet and swirls, which is 3.
P(Swirls) is the total number of bow ties that have swirls,
which is 6 + 3 = 9.
So,
P(Velvet | Swirls) = 3/9 = 1/3
Therefore, the probability that a randomly selected bow tie is made of velvet gave that the bow tie is designed with swirls is 1/3 or approximately 0.33

Find the radius of the two other circles
Answer:
We draw the circles on a coordinate system. We know that a circle is has points that are equidistant from its centerpoint. So the point where these circles are tangent is the midpoint between the centerpoints.
We can use the midpoint formula.
M = ((x1 + x2) / 2 , (y1 + y2) / 2)
M = ((-2 + 6) / 2 , (3 + 9) / 2)
M = (2, 6)
These circles will have the same radii.
If we take the distance between the midpoint and (-2,3), we will have the radius of the circle with this centerpoint.
If we take the distance between the midpoint and (6,9), we will have the radius of the circle with this centerpoint.

The base angles of an isosceles triangle are
congruent. If the measure of each of the base
angles is twice the measure of the third angle,
find the measure of all three angles.
Answer:
base angles each measure 68 degrees
third angle measures 34 degrees
Step-by-step explanation:
let '2x' = measure of each base angle
let 'x' = measure of third angle
the sum of all three must equal 180 degrees so you can write this equation:
2x + 2x + x = 180
combine 'like terms' to get:
5x = 180
divide each side by 5 to get:
x = 34
therefore, twice 'x' is 68
check:
68 + 68 + 34 = 180
180 = 180

x-5y cannot be further simplified unless x and/or y is unknown.

If you know both of the variables values, then you can simply just replace the variables and solve.

Step-by-step explanation:
A triangle has sides of length: 372 +8, 202 + I, and a 3. What is the perimeter of the triangle? Recall that the perimeter is the sum of the sides, 52 + 2x + 5
Given sides of the triangle:
3x^2 + 8,2x^2 + x, andx - 3.We know that the perimeter of a triangle is the sum of all the sides of a triangle.
Perimeter of the triangle,
= 3x^2 + 8 + 2x^2 + x + x - 3
= 3x^2 + 2x^2 + x + x + 8 - 3
= 5x^2 + 2x + 5
Therefore, the perimeter of the triangle is 5x^2 + 2x + 5. Hence, the option A is the correct answer.
The length of a rectangle is twice the width. The area of the rectangle is 82 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answer:
The formula for the area, 'A' of a rectangle whose length and width are 'l' and 'w' respectively is the product of length and width, that is, "A = l × w".
The side length of each square will be √41 units. And the length and width of the rectangle will be 2√41 units and √41 units, respectively.
What is the area of the rectangle?Let W be the rectangle's width and L its length. The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Then the area of the rectangle will be
Area of the rectangle = L×W square units
The length of a rectangle is twice the width.
L = 2W
The area of the rectangle is 82 square units. Then we have
82 = 2W × W
41 = W²
W = √41 units
The side length of each square will be √41 units.
Then the length of the rectangle will be
L = 2√41 units
The length and width of the rectangle will be 2√41 units and √41 units, respectively.
