Abigail realizes that she has too much debt. What is a financially irresponsible decision for Abigail?A.make a budget and limit spending according to the plan

B.take out some easy-access loans and extend them as needed

C.limit spending to writing checks that do not exceed her account balance

D.save $2500 to help pay off debt

Answers

B would be the least wise...loans have interest which means that when you get around to paying them back you owe more than you borrowed and you can get yourself into even deeper debt. Hope this helps, and if you are able to do so, please mark Brainliest! Thanks!

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.

Find y when x=21/2, if y varies inversely as x and x=5 when y=3A. 2.5/3=3/4;6
B. 2.5/3=3/4;3
C. 2.5/3=5/3;6
D. 2.5/3=5/4;3

Answers

y varies inversely as x:
y=C/x
C: Constant

Cross multiplication
yx=C

x=5 when y=3
Replacing in the equation above:
(3)(5)=C

when x=2 1/2=2+0.5→x=2.5, y=?
xy=C
(2.5)(y)=C

Equaling the two equations:
C=C
(2.5)(y)=(3)(5)
2.5/3=5/y

Solving for y. Dividing both sides of the equation by 2.5:
(2.5)(y)/(2.5)=(3)(5)/(2.5)
y=6

Answer:
2.5/3=5/6

If you have a semi-circle with a diameter of 8.6ft, what's the semi-circles area? Use the formula $\pi r^(2)$

Answers

So,

The diameter is 8.6ft. We need to convert to radius.

2 radius = 1 diameter

8.6/2 = 4.3 ft.

$\pi r{2}$

$\pi 4.3^(2)$

$\pi 18.49$

3.14(18.49)

58.0586ft.²

Divide by 2 (semi-circle)
29.0293ft.²
