Answer 1

Answer:

Answer:

B has the greatest range for a given amount of fuel

Step-by-step explanation:

In the US, fuel efficiency is measured in terms of miles per gallon. This value is found by dividing the number of miles traveled by the corresponding number of gallons used.

When calculations are repetitive, it is often useful to use a spreadsheet to do them. You can enter the formula once, and have it operate on all the different data sets. Here, the formula divides the number in the miles column (range) by the number on the same row in the gallons column (fuel).

We find the greatest miles per gallon (best efficiency) is given by Option B.

Additional comment

Many places in the world measure fuel efficiency by the amount of fuel required to deliver a certain outcome. In this problem, that would be expressed as gallons per some number of miles, perhaps 100 miles. Using that measure, a lower value indicates better performance.

The monthly payment for a car lease is $300 for 24 months. The down payment is $1,000. The residual value is $9,000. What is the total cost of the lease? A. 17,200. B. 40,700. C. 8,200

Answers

The total cost of the lease would be $17,200. This is because $300 payment for 24 months is equal to $7,200 + $1,000 (down payment) and + the residual value of $9,000 = $17,200.

The total cost of the lease with a monthly payment of $300 for 24 months and a down payment of $1,000 is C. $8,200.

What is the total cost of a lease?

The total cost of a lease is the sum of the monthly payments and down payment.

The total cost of a lease does not include the residual value of the property.

Data and Calculations:

Monthly payment = $300

Lease period = 24 months

Total monthly payment = $7,200 ($300 x 24)

Down payment = $1,000

Total cost of the lease = $8,200 ($7,200 + $1,000)

Residual value = $9,000

Thus, the total cost of the lease with a monthly payment of $300 for 24 months and a down payment of $1,000 is C. $8,200.

#SPJ9

If a vector pointing upward has a positive magnitude, a vector pointing downward has a negative magnitude. True or false?

Answers

Answer:

The statement is false.

Step-by-step explanation:

For any vector 'r' we have

$\overrightarrow{r}=x\widehat{i}+y\widehat{j}+z\widehat{k}$

The magnitude is given by

$|r|=\sqrt{x^(2)+y^(2)+z^(2)}..........(i)$

As we know that the upon squaring a term the result is always positive thus the term in right side of equation i is always positive no matter weather the terms (x,y,z) are positive or negative hence we conclude that magnitude of any vectorial quantity is always positive irrespective of it's direction.

8k-1=15 ? Help I have a question were we have to work this out what do I do?

Answers

$8k-1=15\ \ \ \ /+1\n\n8k-1+1=15+1\n\n8k=16\ \ \ \ /:8\n\n8k:8=16:8\n\nk=2$

you have to add 1 to the -1 and you will get 0.What you have to do next is also add 1 to 15 because you want a variable on one side and a number on the other.So now you have 8k=16. So you divide 8 to 8k and you get nothing divide 8 and 16 and your answer for k =2 hope you get it right.trust mw it is very easy when you get use to it

A line passes through point (-2, 5) and has a slope of 2/3. Points A(x, 3) and B(-2, y) lie on the line. the value of x is ___, the value of y is ___.

Answers

Use the equation y = mx +c
y = 2/3x +c Substitute the slope (m) in
5 = 2/3(-2) +c Substitute the point (-2,5)
5 = -4/3 +c Make C the subject
c = 19/3

y = 2/3x + 19/3 This is the equation of the line.

Next you start subbing the points A and B in separately, using the same equation.

Subbing A(x, 3)
3 = 2/3x + 19/3 Make x the subject to find it.
-10/3 = 2/3x
-5 = x

The point A is (-5,3)

Subbing B(-2, y)
y = 2/3(-2) + 19/3 y is already the subject and you just solve it
= -4/3 + 19/3
y = 5

The point B is (-2, 5)

1 . The lengths of the legs of a right triangle are 25 cm and 60 cm. What is the length of the hypotenuse?
A. 42.5 centimeters
B. 65 centimeters
C. 9.2 centimeters
D. 35 centimeters

D.

35 centimeters

Answers

$a^(2)+ b^(2) = c^(2)$ that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.'
$25^(2)+ 60^(2)= x^(2)$
625+3600= $x^(2)$
4225= $x^(2)$
Therefore,
$√(4225)$ =x
65=x
The length of the hypotenuse is B.65 centimetres.
