Find the original price of a pair of shoes if the sale price is $40 after a 60% discount

Mathematics
1 answer:
Arturiano [62]3 years ago
3 0

Answer:

<em>Thus, the original price of the pair of shoes was $100.</em>

Step-by-step explanation:

<u>Percentages</u>

After a 60% discount, the sale price is now valued at 100-60=40% of its original price.

If the sale price is $40, then the original price is calculated as

$40 / 40 * 100 = $100

Thus, the original price of the pair of shoes was $100.

Verify applying 60% discount:

$100 - 60*$100/100 =  $40

14(0.89)^x+4.5 =162
lisabon 2012 [21]
14(0.89)^{x + 4.5} = 162
\frac{14(0.89)^{x + 4.5}}{14} = \frac{162}{14}
0.89^{x + 4.5} = 11\frac{4}{7}
ln(0.89^{x + 4.5}) = ln(11\frac{4}{7})
(x + 4.5)ln(0.89) = ln(11\frac{4}{7})
\frac{(x + 4.5)ln(0.89)}{ln(0.89)} = \frac{ln(11\frac{4}{7})}{ln(0.89)}
x + 4.5 = -2101.14032500
x = 2105.64032500

What was your speed if you drove 325 miles in 5 1/4 hours?
Alexus [3.1K]

Answer:

62 miles per hour speed if you drove 325 miles in 5 1/4 hours

Step-by-step explanation:

Using formula:

\text{Speed} = \frac{\text{Distance}}{\text{Time}}

As per the statement:

if you drove 325 miles in 5 1/4 hours

⇒\text{Distance}=325 miles

and

Time = 5\frac{1}{4} = \frac{21}{4} = 5.25 hours

Then by above formula we have;

\text{Speed} = \frac{325}{5.25}=61.90 miles per hour

Therefore, 61.90 ≈ 62 miles per hour speed if you drove 325 miles in 5 1/4 hours

Which equation represents a proportional relationship?choose one
Travka [436]

Answer:

  d. y =1/4x

Step-by-step explanation:

There can be no added constant in an equation expressing a proportional relationship. If the equation is written in standard form (ax+by=c), then the value of c must be zero.

That is, the point (x, y) = (0, 0) must be a solution to the linear equation for a proportional relationship.

How many squares would have to be shaded to that 1/6 of the shape is shaded
Luba_88 [7]

Answer:

3 squares

Step-by-step explanation:

Firstly, you have to count the number of squares in the shape. As it can been seen from the diagram, there are a total 18 squares (i.e 6 squares on each row × 3 squares on each column).

Secondly you have to find 1/6 of the total number of the squares in the shape. 1/6 of the total number of the square in the shape = 1/6 × 18 = 3 squares

Therefore 3 squares would have to be shaded so that 1/6 of the shape is shaded
