Answer:

Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

<u>2006:</u>

top coats is 297,

parkas is 210,

jackets is 213,

raincoats is 137,

trench coats is 103

Total: 297+210+213+137+103=960

<u>2007:</u>

topcoats is 223,

parkas is 210,

jackets is 285,

raincoats is 259,

trench coats is 127

Total: 223+210+285+259+127=1,104

<u>Percent increase in total sales:</u>

\dfrac{1,104-960}{960}\cdot 100\%=15\%

<u>Percent increase in sales of trench coats:</u>

\dfrac{127-103}{103}\cdot 100\%\approx 23.3\%

Since 23.3\%-15\%=8.3\%, sales of trench coats increased 8.3 percentage points faster than total coat sales.

Megan went to the store and bought 4 notebooks and 9 pencils for a total of $8.25. Joanne went to the same store and bought 7 no
Rzqust [24]
Let notebooks be x and let pencils be y

4x+9y=8.25 (equation 1)
7x+14y=14.00 (equation 2)

Multiply equation 1 by 7
So that you get 28x+63y=57.75

Multiply equation 2 by 4
So that you get 28x+56y=56.00

28x+63y=57.75 -
28x+56y=56.00
-----------------------
7y=1.75

Divide both sides by 7
1.75/7 is 0.25

So, now we know that one pencil costs 0.25 cents

Sub this y value into equation one

4x+9(0.25)=8.25

4x+2.25=8.25

Move 2.25 to the other side as a negative number

4x= 6

Divide both sides by 4

6/4 is $1.50

So, one pencil is equal to 0.25 cents and one notebook is equal to $1.50

What 42 rounded to the nearest ten​
Savatey [412]

Answer:

40

Step-by-step explanation:

the tens value is the 2 value from the left of a decimal point.

Examples: 32  67.4  2345 904

In your case, the tens value is 4

We need to look at the ones value to see if we need to round up or down

Because the ones value, 2, is less than 5, we keep the tens value, so it's 40

cestrela7 [59]

We will see that there are 156,000 different combinations, so the correct option is C.

<h3>How many possibilities are there? </h3>

First, we need to find the selections, here we have:

  • First letter.
  • Second letter.
  • Third letter.
  • Number.

Now we need to find the number of options for each of these selections.

  • First letter. (26 options)
  • Second letter. (25 options, because we can't repeat letters)
  • Third letter. (24 options)
  • Number. (10 options).

We assumed that the number can be any integer from 0 to 9.

The total number of possibilities is equal to the product between the numbers of options, we will have:

P = 26*25*24*10 = 156,000

So, the correct option is C.

Ashin has been working in UAE for a decade and saved AED 125,500 which he wants to transfer now to his parent's account in India
saul85 [17]

Answer:

2510000 INR

Step-by-step explanation:

Given

Savings = AED 125500

1\ AED =20\ INR

Required

The amount that will be withdrawn in India

We have:

1\ AED =20\ INR

Multiply both sides by the savings

125500 * 1\ AED =20\ INR * 125500

125500\ AED =125500 * 20\ INR

So, we have:

125500\ AED =2510000\ INR

<em>Hence, the amount that will b withdrawn is: 2510000 INR </em>
