wrangler has 300 dollars to spend on school supplies. He spent 1/10 on notebooks. How much does he have left?
marshall27 [118]

Answer:

Step-by-step explanation:

<u>Method 1:</u>

$300 on school supplies

1/10 on notebooks

As you're finding how much is left:

10/10-1/10=9/10

Convert 9/10 into a decimal

9/10=0.9

300*0.9=$270

OR

<u>Method 2: </u>

1/10=0.1

300*0.1=$30

Take away 30 from $300

$300-30=$270

By using either method, You would still have $270 left.

How this helps!!!

Have a nice day :)

R is inversely proportional to A.
hjlf

Here are the answer: a) R = 3.6 and b) A = 2

Step-by-step explanation:

Given,

R is inversely proportional to A.

R ∝ \frac{1}{A}

so, R = \frac{k}{A}  -------eq 1 where k is any constant

To find the values of a) R when A = 5 and

b) Value of A when R = 9

Now,

Putting R = 12 and A = 1.5 in eq 1 we get,

12 = \frac{k}{1.5}

or, k = 12×1.5 = 18

From eq 1 we get,

R = \frac{18}{A} --------- eq 2

Now,

a) Putting A= 5 in eq 2 we get,

R = \frac{18}{5} = 3.6

b)  Putting R = 9 in eq 2 we get

R = \frac{18}{A}

or, A = \frac{18}{9} = 2

Camille invested money into an account that earned annual simple interest with a rate of 6.5%. She made no additional deposits o
vichka [17]

Answer:

$30341.88

Step-by-step explanation:

Because it says simple interest, use the formula I = Prt.

(I is interest, r is the % rate as a decimal, t is the time)

So, you have to solve the equation,

1755 = P (0.065)(9)

Since 0.065 x 9 = 0.585, the equation can be simplified to

1755 = 0.585P

Then, to get P, you divide both sides by 0.585

P = 1755/0.585 = $30341.88
