Rachel saved money to buy art supplies. She used 13 of her savings to buy brushes. She used 35 of her savings to buy paint. What fraction of her savings does she have remaining?

Answers

Given:

Rachel used [tex]\dfrac{1}{3}[/tex] of her savings to buy brushes.

She used [tex]\dfrac{3}{5}[/tex] of her savings to buy paint.

To find:

The fraction for remaining savings.

Solution:

Fraction that Rachel used of her savings to buy brushes and paint is

[tex]\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}[/tex]

                                    [tex]=\dfrac{5+9}{15}[/tex]

                                    [tex]=\dfrac{14}{15}[/tex]

Now,

[tex]\text{Fraction for remaining savings}=1-\text{Fraction for used amount}[/tex]

[tex]\text{Fraction for remaining savings}=1-\dfrac{14}{15}[/tex]

[tex]\text{Fraction for remaining savings}=\dfrac{1}{15}[/tex]

Therefore, [tex]\dfrac{1}{15}[/tex] of her savings is remaining.

a $260 suit price is marked down 10 % find the sale price

Answers

Answer:

260*0.90=sales price=234

Step-by-step explanation:

Step-by-step explanation: We first need to find the discount.

The formula for discount is shown below.

Original Price × Rate of Discount = Discount

So here, the original price is $260 and the

rate of discount is 10% off which we can write as .10.

So we multiply 260 by .20

260 x .10 gives us 26.

So the discount is $26.

Now let's find the sale price.

The formula for sale price is shown below.

Original Price - Discount = Sale Price

Since the original price is $260 ad the discount is $26,

we have 260 - 26 which gives us 234.

So the sale price of the suit is $234.

Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute.

Answers

Complete question :

Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2?

Answer:

4 minutes

Step-by-step explanation:

Given the following exercise routines :

Routine #1,

Walking : burns 22 calories walking. He then running : burns 10.5 calories per minute.

Routine #2,

Walking : burns 39 calories walking. He then running : burns 6.25 calories per minute.

Let number of tone spent running = t

Hence,

Routine 1 ; calories burned

22 + 10.5t

Routine 2 ; calories burned

39 + 6.25t

Equating the two equations :

22 + 10.5t = 39 + 6.25t

10.5t - 6.25t = 39 - 22

4.25t = 17

t = 17/4.25

t = 4

To prove:

Proof:

In ΔAMD and ΔBMC,

∠M = ∠M                   (∵ Common)

AD = BC                       (∵ opposite sides of ║gm are equal)

∠ADM = ∠CBM           (∵ Alternate angle)

What is 3.5=12s-55

Answers

Answer:

4.875 = s

Step-by-step explanation:

3.5=12s-55

Add 55 to each side

3.5+55=12s-55+55

58.5 = 12s

Divide each side by 12

58.5/12 = 12s/12

4.875 = s

Answer:

s = 4.875

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

3.5 = 12s - 55

Step 2: Solve for s

Add 55 to both sides:                    58.5 = 12sDivide 12 on both sides:                4.875 = sRewrite:                                           s = 4.875

Step 3: Check

Plug in s into the original equation to verify it's a solution.

Substitute in s:                    3.5 = 12(4.875) - 55Multiply:                               3.5 = 58.5 - 55Subtract:                              3.5 = 3.5

Here we see that 3.5 does indeed equal 3.5.

∴ s = 4.875 is a solution of the equation.
