Answer 2
Answer:

Final answer:

If Jim had purchased only one pack of batteries, the change to his account balance would be -$11.97.

Explanation:

This problem describes a mathematical scenario related to buying and pricing. Given that Jim bought 2 packs of batteries for -$23.94, we can infer that this is the total cost for both packs. Therefore, to find the cost of one pack, you will simply divide the total cost by the number of packs.

To do this, −$23.94 should be divided by 2. Using a calculator, this division equals −$11.97. Therefore, the change to Jim's account balance if he had only bought 1 pack of batteries would have been −$11.97.

A rectangle has a perimeter of 80 inches. Write an equation to represent the area A in terms of width w. Do I use the perimeter?

Answers

Answer:

A = 40w-w^2      

Step-by-step explanation:

We are given the following in the question:

Perimeter of rectangle = 80 inches.

Let l be the length and w be the width of rectangle.

Perimeter of rectangle =

P= 2(l+w)

Putting values, we get,

80 = 2(l+w)\n40 = l+w\n\Rightarrow l = 40 - w

Now, we have to find the area of the rectangle in terms of w.

Area of rectangle =

A = l* w

Putting values, we get

A = (40-w)w\nA = 40w-w^2

is the required expression of area of rectangle in terms of w.

Yes, the perimeter is used to calculate the length of the rectangle in the term of w.

A tailor used 2 meters of string to make 10 Halloween masks. He used _ of a meter for each mask.

Answers

Answer: He used (1)/(5) of a meter for each mask.

Step-by-step explanation:

Given : A tailor used 2 meters of string to make 10 Halloween masks.

Here, Total length of string = 2 meters

Number of masks = 10

The the part of a meter of string is used for each Halloween mask will be :-

(2)/(10)=(1)/(5) \text{ meter}  [Divide total length of string by number of masks]

Hence, he used (1)/(5) of a meter for each mask.
one fifth of a meter for each mask
2/10=1/5

1.How do you solve an area of a triangle by the base and height?2.What is the area of a triangle that has a base of 15 1/4 inch. And a height of 18 inch

Answers

1. ANSWER: You can solve an area of a triangle by the base and height by using the formula: A=1/2*b*h, where A= Area, b= base, and h=height.
2. ANSWER: First, use the formula: A=1/*b*h. Then substitute those variables to get A=1/2*15.25*18. Then, solve to find the area. 15.25*18=274.5. 1/2*274.5=137.25. 
Therefore, the answer is Area=137.25 inches squared!
