What is the volume of air in a lab of dimensions 8 mx 5 m x 3 m?
What is the mass of the air? (Density of air = 1.3 kg/m3)
Answer:
Volume of air = 120 m³
Mass of air = 156 kg
Step-by-step explanation:
Volume of air in a lab of dimensions,
= 8 x 5 x 3
= 120 m³
Mass of the air ?
Given : Density of air = 1.3 kg/m³
Formula : -
Density = Mass / Volume
Mass = Density x Volume
= 1.3 x 120
Mass = 156 kg

In January, 1950, the minimum wage was $.75. What should the minimum
wage be in July, 2009?
Answer:
On July 24, 2009, the federal minimum wage will increase to $7.25 per hour. This is the final step of a three-step increase passed in 2007 when the minimum wage was only $5.15. In this last step, about 4.5 million workers will receive a raise, providing an additional $1.6 billion annually in increased wages. However, when adjusted for inflation, the new federal minimum is still less than the minimum wage through most of the period from 1961 to 1981.

Answer:
324 ft²
Step-by-step explanation:
Given 2 similar figures with ratio of sides a : b , then
ratio of areas = a² : b²
Here ratio of sides = 3 : 18 = 1 : 6
ratio of areas = 1² : 6² = 1 : 36
That is the area of the larger parallelogram is 36 times the smaller
area of larger parallelogram = 36 × 9 = 324 ft²
The circle graph represents the after-tax budget for the Williams family. If the total monthly budget is $3050, which is the best estimate for the food budget?
The best estimate for the food budget will be the percentage of the food budget multiplied by $3050.
This is an incomplete question, therefore, an overview of the question will be given. Since you didn't provide the percentage of the food budget, let's assume that the percentage is given as 20%. Therefore, the food budget will be;
= 20% × $3050
= 0.2 × $3050
= $610
The food budget will be $610.

You spent a total of $63. How much will pay in 6% tax?
Answer:
You will pay $3.78 in tax. And you would pay a total of $66.78
Step-by-step explanation:
Answer: $3.78 or $66.78 if you are looking for the total amount including tax.
Step-by-step explanation:
6% can be represented by 0.06 so multiply that by 63
63*0.06=3.78
You will pay $3.78 in taxes
The total is 66.78 but I think you are asking for the tax.

midpoint of AC
A. 18
B. 6
C.27
D.54
Answer:
D
Step-by-step explanation:
Since B is the midpoint of AC , then
AB = BC , substitute values
4x + 3 = 3x + 9 ( subtract 3x from both sides )
x + 3 = 9 ( subtract 3 from both sides )
x = 6
Then
AC = AB + BC
= 4x + 3 + 3x + 9
= 7x + 12
= 7(6) + 12
= 42 + 12
= 54 → D

Kira is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges an initial fee of $35 and an additional 60 cents for every mile driven.
Company B charges an initial fee of $42 and an additional 50 cents for every mile driven.
For what mileages will Company A charge less than Company B?
Write your answer as an inequality, using m for the number of miles driven.
Answer:
m < 0.7
Miles less than 0.7
Step-by-step explanation:
Company A: 60m + 35
Company B: 50m + 42
60m + 35 < 50m + 42
60m - 50m < 42 - 35

Suppose f(x) = 5x - 4. Describe how the graph of g compares with the graph of f.
g(x)=f(x) + 12
IDEE
Select the correct choice below, and fill in the answer box to complete your choice.
O A. g(x) has a scale factor of compared to f(x). Because it scales the horizontal direction, the graph is stretched horizontally.
OB. The graph of g(x) is translated unit(s) to the left compared to the graph of f(x).
OC. The graph of g(x) is translated unit(s) down compared to graph of f(x).
OD. g(x) has a scale factor of compared to f(x). Because it scales the vertical direction, the graph is stretched vertically.
O E. g(x) has a scale factor of compared to f(x). Because it scales the horizontal direction, the graph is compressed horizontally.
O F. g(x) has a scale factor of compared to f(x). Because it scales the vertical direction, the graph is compressed vertically.
O G. The graph of g(x) is translated unit(s) to the right compared to the graph of f(x).
O H. The graph of g(x) is translated unit(s) up compared to graph of f(x).
The graph of g(x) and f(x) are related by the given equation g(x) = f(x) + 12,
therefore, the ordered pair of the graph of g(x) is (f(x) + 12, x).
The choice that correctly describes how the graph of g(x) compares with f(x)
is the option; H. The graph of g(x) is translated unit(s) up compared to graph
of f(x).
Reasons:
The given function is f(x) = 5·x - 4
The function g(x) = f(x) + 12
Required:
To select the correct choice from the given options
Solution:
The difference between f(x) and the required function, g(x), is the addition
of a constant positive value of 12 to the function f(x).
Therefore, each f(x) output value is further increased by 12 to obtain the
graph of g(x), which gives;
The graph of g(x) is translated 12 units up compared to the graph of f(x),
which corresponds with the option H.
