The car will need approximately 8.76 more gallons of gas to complete the remaining 440 miles of the 650-mile trip, assuming it continues to get the same mileage rate of 26.25 miles per gallon.
Explanation:To calculate the additional amount of gas needed to complete the 650-mile trip, given that the car used eight gallons to travel the first 210 miles, we need to find the car's mileage rate and then determine how much more gas is required for the remaining distance.
Step-by-Step Explanation
Therefore, the car will need approximately 8.76 more gallons of gas to complete the rest of the trip at the same rate.
To calculate the additional gas needed for the remainder of a 650-mile trip after using 8 gallons for the first 210 miles, first determine the gas mileage and then calculate the gas required for the remaining 440 miles. The car will need approximately 16.76 more gallons of gas to complete the trip.
Explanation:To determine how much more gas you will need to complete your 650-mile trip, after having used 8 gallons for the first 210 miles, you need to calculate your car's gas mileage and then use that information to find the amount of gas needed for the remaining distance.
First, let's compute your car's mileage:
Gas mileage = Distance driven / Gallons of gas usedGas mileage = 210 miles / 8 gallonsGas mileage = 26.25 miles per gallon (mpg)Now, let's subtract the miles you have already traveled from the total trip length to find the remaining miles:
Remaining distance = Total distance - Distance already traveledRemaining distance = 650 miles - 210 milesRemaining distance = 440 milesFinally, we calculate the amount of gas needed for the remaining distance:
Gallons needed = Remaining distance / Gas mileageGallons needed = 440 miles / 26.25 mpgGallons needed = approximately 16.76 gallonsTherefore, you will need approximately 16.76 more gallons of gas to complete your trip, assuming the gas mileage remains consistent.

We have to factorize the given polynomial completely.
Consider the given polynomial [tex]21x^3+35x^2+9x+15[/tex]
We will solve it by grouping of terms,
Grouping is collecting terms having some factors common
Taking [tex]7x^2[/tex] common from first two term and 3 from last two terms , we have,
[tex]21x^3+35x^2+9x+15[/tex]
[tex]\Rightarrow 7x^2(3x+5)+3(3x+5)[/tex]
Now taking (3x +5) common from both terms , we have,
[tex]\Rightarrow (7x^2+3)(3x+5)[/tex]

f.?
The conversion of fahrenheit to degree celsius for f = 113 is 45 degree celsius
What is a mathematical expression?
When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions as yet unlearned, the resulting combination of mathematical symbols is called a mathematical expression.
Given, formula of temperature conversion of degree celsius to fahrenheit
c=5/9(f-32)
If f = 113
then putting the value on the equation, we get
c = 5/9(113-32)
c = 5/9(81)
c = 5*9
c = 45 degree celsius
Therefore, The conversion of fahrenheit to degree celsius for f = 113 is 45 degree celsius

(1.8 * 10^2) * (5 * 10^2)
The total cost in dollars to produce q units of a product is C(q). Fixed costs are $13000 . The marginal cost is C'(q)=0.006q^2-q+50.
Estimate C(170) , the total cost to produce 170 units.Find the value of C'(170). Then combine these to find C(171).
To find the cost of production for 170 units, consider both fixed costs and variable costs (the integral of the marginal cost function). The cost of producing 171 units can be estimated by adding the marginal cost for the additional unit.
Explanation:The quantity of interest is C(170), the total cost to produce 170 units. To estimate this value, you can calculate the fixed costs plus the integral of the marginal cost from 1 to 170 (the number of items produced).
So, first, calculate the fixed costs which is given as $13000.
Next, estimate the total variable costs, which is the integral of the marginal cost function over the range from 1 to 170 units. Given marginal cost function is C'(q) = 0.006q^2-q+50. Use the power rule to integrate the function, then evaluate it at q=1 and q=170 and subtract.
The value of C'(170) is simply the value of the marginal cost function at q=170.
After finding the value of C(170) and C'(170), the total cost to produce 171 units, C(171), is approximately the total cost to produce 170 units plus the marginal cost to produce the 171st unit.

I would like to purchase 20 products at a cost 65.00 per product. what will be my total? your state has 3.5% sales tax
The total is: $ 1345.5
Step-by-step explanation:It is given that:
I would like to purchase 20 products at a cost 65.00 per product.
This means that the cost of 20 products will be:
[tex]20\times 65=\$\ 1300[/tex]
Also, there is a sales tax of 3.5%
This means that a person has to pay a extra 3.5% on the total cost of the items he purchased.
i.e. he need to pay 3/5% on $ 1300
This means that the amount of tax he need to pay is: 3.5% of 1300
= 3.5%×1300
= 0.035×1300
= $ 45.5.
Hence, the total cost is: $ 1300+$ 45.5
This means that the total cost is: $ 1345.5
