Ronch [10]2 years ago
6 0

Answer:

It would be 20

Step-by-step explanation:because you have to divide 320 by 2 which equals $160 for 1 year and then divide that by 2 again would be $80 for 6 months then divide it by 2 again which would be $40 and 3 months for it then divide it by 2 again and 1 and a half months equal $20

Answer:

x = 10

y = 14

Step-by-step explanation:

Here, we want to get the values of x and y

Since all sides are equal, the internal angle is 60 degrees for each internal angle

Since AC = 14

Then y is also 14 since what we have is an equilateral triangle

Secondly ;

6x = 60

x = 60/6

x = 10

Which expression is equivalent to<br> 200?<br> O2./10<br> 1012<br> 10./20<br> 1002
solong [7]

Hey there!

We know options. B and D aren't going to be your answer because they are way too big to be equivalent to 200

In order for you to find out which one is equivalent to 200 you have to calculate you late the options until you get to 200 and then you could do process of elimination!

It can't be A because 2/10 = 0.20 aka 20%

It can't be option. C because 10/20 = 0.50 aka 50%

So none of the above would be your answer

The correct answer would most likely be: 10√2

Good luck on your assignment and enjoy your day!

At first a price was decreased by 12%, then it was discounted again by an additional 5%. What is the percent of the total discou
olga_2 [115]
Hello there! I can help you! So we are decreasing a price by 12% and then doing it again by 5%. We would pay 88% of the original price and then 95% of that sale price. To execute this better, let's make a real-world situation. Say that Mariana wants to buy a new pair of shoes that originally costed $100. The store has a tag for 12% off and then an additional 5% discount at the counter. How much would she pay for the shoes? What total discount does she get? Let's start by multiplying 100 by 88%. 100 * 88% (0.88) is 88. That's the first part. Now, we multiply that number by 95% to find the price at the counter. 88 * 95% (0.95) is 83.6. That's the price with both discounts. Mariana would pay $83.60 for the shoes, but what about the percent discount total? Let's subtract that price from 100 and see what we get. 100 - 83.6 is 16.4. Percents are parts of 100, so we don't need to do anymore simplifying. There. The total amount of discount is 16.4%.

A farmer is building a fence to enclose a rectangular area against an existing wall, shown in the figure below.
Annette [7]

The most appropriate choice for maxima and minima of a function will be given by

Rectangle of length 72 feet and breadth 36 feet has largest area

What is maxima and minima?

Maxima of function f(x) is the maximum value of the function and minima of function f(x) is the minimum value of the function.

Here,

Let the length be x feet and breadth be y feet

The farmer has 144 feet of fencing

Three of the sides will require fencing and the fourth wall already exists.

So,

x + y + y =1 44

x + 2y = 144

Area of rectangle(A) = xy ft^2

                               = (144 - 2y)y

                               = 144y - 2y^2

\frac{dA}{dy} = \frac{d}{dy}(144y - 2y^2)

     = 144 - 2\times 2y^{2-1}\\144 - 4y

For largest area,

\frac{dA}{dy} = 0

144 - 4y = 0 \\4y = 144\\y = \frac{144}{4}\\y = 36

\frac{d^2A}{dy^2} = \frac{d}{dy}(144 - 4y)\\=0-4\\=-4 < 0

Hence area is maximum

For largest area, y = 36 feet

x = 144 - 2\times 36\\x = 144-72\\

x = 72 feet

So length of rectangle is 72 feet, breadth of rectangle is 36 feet
