Haden drove 525 miles and used 25 gallons of gas. How many miles did Haden's car travel per gallon of gas? *
Answer:
21 miles per gallon of gas
Step-by-step explanation:
Solving the above question:
25 gallons of gas = 525 miles
1 gallon of gas = x miles
Cross Multiply
25 gallons × x miles = 525 miles × 1 gallons
x miles = 525 miles/25 gallons
x = 21 miles
Therefore, the miles that Haden's car travelled per gallon of gas is 21 miles per gallon of gas

1)
[tex]\sqrt[5]{16} * \sqrt[5]{2} \\= 16^{1/5} * 2^{1/5}\\= 2^{4(1/5)} * 2^{1/5}\\= 2^{4/5} * 2^{1/5}\\= 2^{4/5+1/5}\\= 2 ^{5/5}\\= 2^1\\= 2\\\\[/tex]

Given the expression below and based on the values that are given, what will the sign of the product be? -4*(-8/9)*2.78*(1 1/3)*(-2/5)*(-6.2)*(0.2873)*(3 1/11)* A
Answer:
The sign on the end result is +
Step-by-step explanation:
Given
[tex]-4*(-8/9)*2.78*(1\ 1/3)*(-2/5)*(-6.2)*(0.2873)*(3\ 1/11)[/tex]
Required
Determine the sign of the result
To do this, we simply write out the product of the sign of individual digit.
[tex]-4*(-8/9)*2.78*(1\ 1/3)*(-2/5)*(-6.2)*(0.2873)*(3\ 1/11)[/tex] becomes
[tex]- * - * + * + * - * -* + * +[/tex]
Group the product in 2's
[tex](- * -) *( + * +) *( - * -)* (+ * +)[/tex]
As a general rule:
[tex]- * - = +[/tex]
[tex]- * + = -[/tex]
[tex]+ * - = -[/tex]
[tex]+ * + = +[/tex]
Apply this rule on the above;
[tex](- * -) *( + * +) *( - * -)* (+ * +)[/tex] becomes
[tex]+ * + * + * +[/tex]
Group in 2's
[tex](+ * +) * (+ * +)[/tex]
Apply the rule
[tex]+ * +[/tex]
Finally, this gives:
[tex]+[/tex]
Hence, the sign on the end result is +

A 25 -pound bag of dog food costs $20.25 A35 -pound bag of the same dog food costs $27.65 Which bag of dog food is the better buy?
Answer:
The 35 pound bag
Step-by-step explanation:
If you divide the price of the 25 pound bag by the number of pounds it has you get 0.81 dollars per pound
20.25 / 25 = 0.81
However if you divide the price of the 35 pound bag by the number of pounds it has you get 0.79 dollars per pound
27.65 / 35 = 0.79
This means you get more dog food for less in the larger 35 pound bag

What is the slope of the following equation? 8x+3y=9
Answer:
The answer is -8/3.
Step-by-step explanation:
First, you have to make y the subject :
8x + 3y = 9
3y = -8x + 9
y = (-8/3)x + 3
In a linear equation, y = mx + b, m represent gradient (slope). So in this equation the slope is -8/3.

A factory makes rectangular sheets of cardboard, each with an area of 2 1 2square feet. Each sheet of cardboard can be cut into smaller pieces of cardboard measuring 1 6square feet. How many smaller pieces of cardboard does each sheet of cardboard provide?
Answer:
2 1/7 pieces
Step-by-step explanation:
A factory makes rectangular sheets of cardboard, each with an area 2 1/2 square feet. Each sheet of cardboard can be cut into smaller pieces of cardboard measuring 1 1/6 square feet. How many smaller pieces of cardboard does each sheet of cardboard provide?
Each sheet of cardboard = 2 1/2 square feet
Each smaller pieces of cardboard = 1 1/6 square feet
Number of smaller pieces of cardboard per sheet of cardboard = Each sheet of cardboard ÷
Each smaller pieces of cardboard
= 2 1/2 square feet ÷ 1 1/6 square feet
= 5/2 ÷ 7/6
= 5/2 × 6/7
= (5*6) / (2*7)
= 30/14
= 15/7
= 2 1/7 pieces
Number of smaller pieces of cardboard per sheet of cardboard = 2 1/7 pieces
A restuarant bill before tax is $63.50, if the sales tax is 7% and a 18% tip was added what is the total cost of the meal
Answer:
$79.375
Step-by-step explanation:
Given that:
Bill before tax = $63.50
Tax = 7%
Tip added = 18%
Hence,
Tax = 7% of bill before tax
Tax amount = 0.07 * 63.50
Tax amount = $4.445
Tip amount = 0.18 * 63.50
Tip amount = $11.43
Total meal cost :
Before tax cost + tax amount + tip amount
$(63.50 + 4.445 + 11.43) = $79.375

Sylvia and Patrick plotted the information they gathered on the weight of cars and the mileage they get. Then they each drew a line on the graph
that they felt best fit the data,
Sylvia's line blank
a line of best fit because her line blank .
Patrick's line blank
a line of best fit blank
as his line blank.
Answer:
The correct options are;
a) Is
b) Passes through the middle of the plotted scatter data points on the graph
b) Is not
e Does not pass through the middle of the plotted scatter data points on the graph
Step-by-step explanation:
Whereby the graph with the line of best fit on the left was drawn by Sylvia and the graph with the line of best fit on the right was drawn by Patrick, we have;
The line of best fit is a line that gives the relationship of the data points within a graph to each other, such that the line of best fit provides an approximation of the data on a graph
The line of best fit is the line that passes through the mid region of all the scatter points within a graph, and closeness of the data points on the scatter plot to the line of best fit, the higher the level of correlation between the line of best fit and the data.
Therefore, we have;
Sylva's line is a line of best fit because her line passes through the middle of the plotted scatter data points on the graph. Patrick's line is not a line of best fit as his line does not pass through the middle of the plotted scatter data points on the graph.
Answer: Sylvia’s line is a line of best fit because her line is close to most of the data points . Patrick’s line is not a line of best fit as his line is not close enough to all the data points .

Solve for c.
a(c + b) = d.
Answer:
c = d/a - b
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define
a(c + b) = d
Step 2: Solve for c
Divide a on both sides: c + b = d/aSubtract b on both sides; c = d/a - bJoey Chestnut is trying to break his own record for eating the most whole hot dogs in 10 minutes. He needs to eat more than 72 hot dogs to break his record. After 1 minute, Joey has eaten 11 1/4 hot dogs. Let ddd represent the number of hot dogs Joey eats per minute for the next 999 minutes. Which inequality represents the number of hot dogs per minute Joey could eat for the last 999 minutes to break his record?
Answer:
d > 6 3/4
Step-by-step explanation:
Given that:
72 hot dogs in 10 minutes is required to break Record ;
Consumption after 1 minute = 11 1/4 hot dogs
Number of hotdogs consumed per minute for the next 9 minutes = d
Number of consumption per minute required to break record :
d = (72 - 11 1/4) / 9
d = (60 3/4) ÷ 9
d = (243 / 4) * 1/9
d = 243 / 36
d = 6 3/4 hotdogs per minute
Hence, to break record. Consumption must be > 72 hotdogs in 10 minutes
Hence,
d > 6 3/4
Suppose that the original price of a short is 40$ which is better 60% discount of a discount of 30 followed by a discount of 35
Answer:
60% discount is the better buy
Step-by-step explanation
Step one
Original price =$40
Let us compute the various discounts and compare the prices
For 60%
=60/100*40
=0.6*40
=$24
New price = 40-24= $16
For 35%
=35/100*40
=0.35*40
=$14
New price = 40-14= $26
