Brayden deposited $2700 into a savings account that has an annual simple interest rate of 0.3%. find the amount in the savings account after each number of years.

Answer:

year 7 have 135 students

year 9 have 45 students

Step-by-step explanation:

200=total students

360=value of the whole chart

1/2×360

=180

year 8 have 180students

360-180=180

the students remain are 180

1/4×180

=45

year 9 have 45 students

180-45

=135

year7 have 135 students

A fter solving system of equations, we can conclude that, you should buy 60 Polo Shirts, 20 T- Shirts, 120 Rugby Shirts.

Let, x be the number of T-shirts, y be the number of polo shirts and z be the number of rugby shirts

A clothing store and budget $6000 to restock 200 shirts.

So, we get an equation,

x + y + z = 200                      ...................(1)

If you want to have twice as many rugby shirts as polo shirts.

So, we get an equation,

z = 2y                                   ......................(2)

You can buy T-shirts for $12 each, polo shirts for $24 each, and rugby shirts for $36 each.

So, we get an equation,

12x + 24y + 36z = 6000

We rewrite above expression as,

x + 2y + 3z = 500                         ..............(3)

Now we substitute z = 2y, into equations (1) and (3)

x + y + 2y = 200

x + 3y = 200                               ..................(4)

and equation (3) becomes,

x + 2y + 3(2y) = 500

x + 8y = 500                               ...............(5)

After solving equations (4) and (5) we get,

y = 60 and x = 20

Now substitute above value of y in equation z = 2y

z = 2(60)

z = 120

Therefore, after solving system of equations, we can conclude that, you should buy 60 Polo Shirts, 20 T- Shirts, 120 Rugby Shirts.

Simplification the expression in scientific notation 3.6 x 10^(-5)

What is Simplification ?

To implify is to make something simple. In mathematics, simply or simplification means reducing the expression/fraction/problem in a simpler version. Calculations and problem-solving techniques simplify the issue.

We have to multiply the expression

(9x10^-3) (4x10^-3)

We can rewrite this multiplication as

(9 x 4) x (10^-3 x 10^-3)

Now, use the exponent rule,

a^n x a^m = a^(n+m)

(9 x 4) x (10^(-3-3))

(9 x 4) x (10^(-6))

36 x 10^(-6)

It is clear that a numerical term can only be evaluated from an expression filled with numbers (no variables). In the expression provided, we have two variables, where y is being subtracted from x.

The expression can't be simplified because there is no like terms in the expression. However, since there are specific numerical values for each variable, we can substitute the numerical values for the variables in the expression and simplify the expression.

As planned, let's substitute the variables into the expression

Here, we know that x = -2 and y = -3.

If -2 is being subtracted by a negative integer, the negative integer will become positive, and the "minus sign" will be converted to a "plus sign".

We can conclude that 1 is the solution to the expression.

The percentage of customers who chose whole wheat bread with turkey are 19 %.

Given that:-

Percentage of customers who preferred white bread = 55 %

Percentage of customers who preferred turkey with white bread = 46 % of those who like white bread.

Percentage of customers who preferred ham with whole wheat bread = 55 %

We have to find the percentage of customers who chose whole wheat bread with turkey.

Let the total number of customers at the local sandwich shop be 100x.

Percentage of customers who preferred whole wheat bread = (100-55) % = 45 %

45 % of 100x = 45x.

Percentage of customers who preferred turkey with whole wheat bread = (100-58) % of 45x = 42 % of 45x.

Step-by-step explanation: I had the same question.

Swimmer is 47 dm away from the sailboat.

The mentioned problem will use cosine trigonometric functions to find the distance between swimmer and sailboat. Assuming the distance between lifeguard and swimmer be x and the distance between lifeguard and sailboat be y.

Taking the triangle between swimmer and lifeguard -

cos theta = base/hypotenuse

cos 32 = x/36.5

x = 0.8×36.5

x = 29.2 dm

Taking the triangle between lifeguard and sailboat -

cos 13 = y/84.7

y = 0.9×84.7

y = 76.23 dm

Therefore, the distance between sailboat and swimmer is y - x

Distance = 76.23 - 29.2

Performing subtraction

Distance = 47.03 dm

Round to nearest tenth

Distance = 47 dm

Thus, the sailboat and swimmer are 47 dm apart.

As a result, angle M's supplement is 167 degrees, while angle M's complement is 77 degrees.

Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°. The sum of complimentary angles is 90 degrees. If the two additional angles are combined, they create a straight line and an angle.

Complementary angles are those whose combined angle is 90 degrees or less. To put it another way, two angles are said to be complimentary if they combine to make a right angle. In this case, we say that the two angles work well together.

So as per the given information:

we know that

a).  180-angle M=supplement of angle M

180-13=167 degree

b).  90-angle M=compliment of angle M

    =77 degree

Answer:  The correct answer is:  " - 10 ".

___________________
      However, this answer, " -10 ", does not correspond to any of the answer choices given.
___________________

Step-by-step explanation:

Given:  -9 −︱9 + (-3) + (-5)︱ ;

We are to simplify this expression by using the 'order of operations'—as follows:
__________________
BE  MD AS   ;  or:  PE  MD AS
       ⇒   ⇒                      ⇒    ⇒
__________________
  which is a mnemonic device to remember the "order of operations":
       Be Excused, My Dear Aunt Sally (Susan).

or:  Please Excuse My Dear Aunt Sally (Susan).

Note:  the "B" stands for "Brackets" ,
and the  "P" stands for "Parentheses."

Note that "parentheses" can function as "brackets."
The "E" stands for "Exponents".
 → The "Brackets/Parentheses" —if they occur; take priority.

Then:  MD for "Multiplication and Division" are the next priority;
            ⇒
________
 →  and that neither takes priority over the other. Take note of the " ⇒ " symbol" below the "MD".  This means that we perform "multiplication and division"—as they occur, from the far left of ["beginning of"] the expression to the end of the expression.
 Then:  We do the same with "Addition and Subtraction"—from the beginning to the end of the expression, in that order [that is, from "left to right"—as/if they occur]—hence the "⇒" notation.
_____________________
So again, our given expression is:
 " -9 −︱9 + (-3) + (-5)︱ " ;

So; we have an "absolute value" (the positive integer of what is enclosed within the "vertical lines" that indicate "absolute value"—or, if the value of what is enclosed within the "vertical lines" is "0" [zero], then the absolute value would be "0" [zero]; since the absolute value of 0 is 0.
____________
So, let's start simplifying by using the 'order of operations.'
  Do we have brackets or parentheses?  No; except for the absolute value lines — which do take priority. The parentheses within those lines do not count for our purposes—but if they did, then we would use the order of operations within the "absolute value" bars!
       So as a matter of 'semantics', we could say: 'Yes"; that the absolute value bars function as "brackets."

 Do we have any "exponent(s)"?  No.
 Is there any multiplication/division? No.
 Do we have any addition or subtraction?  Yes; only one:
              →   " - 9 −︱9 + (-3) + (-5)︱.
             →   {not including the addition and subtraction within the absolute value bars.}.
____________
Let's start by simplifying the expression within the absolute value bars:
  ︱9 + (-3) + (-5)︱;

Note: The only operations are additional and subtraction; so we just calculate from left to right; as these operations  occur:
 " 9 + (-3) " = 9 − 3 " ;  Note:  Adding a "negative value" is the same as subtracting a "possible value" ;
 to get:  " 6 " ;  
 Then:  the next step is:
     " 6 + (-5) " = 6 − 5 " ;  Note:
Adding a "negative value" is the same as subtracting a "positive value" ;
      to get:  " 1 ".
Now, the absolute of  " 1" is " 1".

 → or; write as: ︱1︱= 1 .  

Now, we can rewrite the entire expression:

 " - 9 − 1 " ;  to calculate and simplify:  
   to get:  " - 10 " .
