By 8:00 a.m., the snack bar had made $3,256 in sales. By noon, the snack bar’s total sales were $8,821. About how much money did the snack bar take in each hour between 8:00 a.m. and noon?
$814.00
$1,391.25
$2,205.25
$5,565.00
Answer:
b) $1,391.25
Step-by-step explanation:
Noon is at 12pm, so 8am-12pm will be 4 hours.
8821-3256=5565, so the snack bar made $5565 in 4 hours, to find how much it made in 1 hour we need to divide 5565 by 4.
5565/4=1391.25

8. A car consumes 25.00 liters of fuel when driving a distance of 400.0 km. How many
gallons will it consume when driving 250.0 miles?
The amount of fuel required to drive 250 miles will be 25.14 liters.
What is an expression?Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that a car consumes 25.00 liters of fuel when driving a distance of 400.0 km. The amount of fuel required for 250 miles will be calculated as:-
1 km = 0.6213 miles
400 km = 400 x 0.6213 miles
400 km = 248.52 miles
248.52 miles = 25 litres
1 mile = 25 / 248.52 litres
250 miles = ( 250 x 25 ) / 248.52 litres
250 miles = 25.14 litres
Therefore, the amount of fuel required to drive 250 miles will be 25.14 liters.

The mathematical relationship between the total cost for a person to bowl at the local bowling alley and the number of games played is represented by y = 3.50x + 6.00 explain how you can use this linear function to find out how many games you can bowl for $34.
If the mathematical relationship between the total cost for a person to bowl at the local bowling alley and the number of games played is represented by y = 3.50x + 6.00, then the number of games you can bowl for $34 is equal to 8.
A linear function can be described as an equation in which the highest power of the variables is not more than 1. As the linear function given is;
y = 3.50x + 6.00
Here y represents the total cost and x represents the number of games played.
We can find the number of games you can bowl for $34 as follows;
y = 3.50x + 6.00
34 = 3.50(x) + 6.00
34 - 6.00 = 3.50(x)
28 = 3.50(x)
x = 28 ÷ 3.50
x = 8
Hence, the number of games you can bowl for using the equation y = 3.50x + 6.00 is calculated to be 8.

What is the sum of rational and Irrational Numbers?Rational numbers are numbers that can be expressed as the ratio of two integers while Irrational numbers cannot be expressed as the ratio of two numbers.
The sum of a rational and an irrational number is always an irrational number.
Example:
Consider a rational number: 4 and an irrational number: 2.7582...
When we add these two numbers, we get,

A used-boat dealership buys a boat for 2600 then sells it for 4100 whats the percent increase? please help!!!
The percentage increase from the boat price of 2600 to 4100 is 57.69%
How to determine the percentage increase?The given parametes are
Cost price = 2600
Selling price = 4100
The percentage increase in the price of the boat is calculated as
Percentage increase = (Selling price - Cost price)/Cost price * 100%
Substitute the known values in the above equation
So, we have
Percentage increase = (4100 - 2600)/2600 * 100%
Evaluate the difference in the above equation
So, we have
Percentage increase = 1500/2600 * 100%
Evaluate the quotient in the above equation
So, we have
Percentage increase = 0.5769 * 100%
Evaluate the product in the above equation
So, we have
Percentage increase = 57.69%
Hence, the percentage increase from the boat price of 2600 to 4100 is 57.69%

The cube root of any given number is that number which we can multiply 3 times by itself to get the original number. It is denoted by ∛, for example- the cube root of x will be ∛x. It can also be written as (x)^1/3.
Here, we are given the expression ∛4 - 2∛4
We can also write this expression as follows-∛4 (1 - 2)= ∛4(-1)= - ∛4

Sue has 20 biscuits in a tin.
There are: 12 plain biscuits
5 chocolate biscuits
3 currant biscuits
Sue takes at random two biscuits from the tin.
Work out the probability that the two biscuits were not the same type.
=======================================================
Explanation:
Define the following three events:
A = plain biscuitB = chocolate biscuitC = currant biscuitNotation like P(A) = 12/20 means the probability of event A (aka picking the plain biscuit) is 12/20 since there are 12 plain biscuits out of 20 total. I'll leave the fraction un-reduced so we can see where the 12 and 20 come from. Going from 12/20 to 3/5 has us lose vital information about the original values.
Notation like AB means a plain biscuit was selected first and then a chocolate biscuit is selected second in that exact order. I'm assuming the first selection is not replaced. This makes the probability of the second selection dependent on the first.
So,
P(AB) = P(A)*P(B given A) = (12/20)*(5/19) = 3/19
P(AC) = P(A)*P(C given A) = (12/20)*(3/19) = 9/95
P(BC) = P(B)*P(C given B) = (5/20)*(3/19) = 3/76
The last step is to add those results to get the probability of event AB, event BC or event AC of occurring. Addition is possible since the events are mutually exclusive.
P(AB)+P(AC)+P(BC) = 3/19 + 9/95 + 3/76 = 111/380

In the diagram, AOC = 144 degrees, APC = 145 degree and onis the center of the circle. Find BAD.
===========================================================
Explanation:
Central angle AOC is 144 degrees. This means arc ABC is 144 degrees because the central angle subtends this arc.
The remaining bit of the circle is 360-144 = 216 degrees. If we placed point E somewhere on the edge of the circle, toward the bottom, then major arc AEC is 216 degrees in measure.
Notice how inscribed angle ADC subtends this 216 degree arc. So according to the inscribed angle theorem, angle ADC is half of the 216 degree arc at 216/2 = 108 degrees.
Angle APD = 180 - (angle APC) = 180 - 145 = 35 degrees
------------------------
Focus solely on triangle ADP. We have these interior angles
A = unknownD = 108P = 35The three interior angles must add to 180
A+D+P = 180
A+108+35 = 180
A+143 = 180
A = 180-143
A = 37 which is the measure of angle BAD.

Given, the volume of a pine tree shaped like a cone is 3887.2 cubic feet also given that it has a radius of 8 feet,
∴ We can obtain the height of the pine tree by equating given volume with the formula and substituting the value of radius.
So, (1/3)π(8)²h = 3887.2.
(1/3).(3.14).(64)h = 3887.2.

Write each expression in simplest form. (x¹/₂y⁻²/₃)⁻⁶
The given expression can be simplified by using the rule of negative exponent.
In the expression, there are two terms with negative exponent. The second base term y has a negative exponent -2/3. The second negative exponent -6 is applied to both base terms.
The rule states that the negative exponent can be solved by reciprocating the base term i.e. a^-x=1/a^x.
Solving the negative exponent for y,
Hence, x^1/2y^-2/3=x^1/2/y^2/3.
Solving the second negative exponent -6 that applies to both terms, applying the same rule i.e. a^-x=1/a^x.
(x^1/2/y^2/3)^-6=(y^2/3/x^1/2)^6
Multiplying the powers and simplifying,
y^2/3*6/x^1/2*6=y^4/x^3
