A pair of sunglasses is on sale for $17. Last week, the sunglasses were marked at a regular price of $20. What was the percent of change?

Answers

Answer:

15%

Step-by-step explanation:

17/20 the 17 is the part, and the 20 is the whole

17/20 = x/100

cross multiply

17*100= 1,700 divide by 20

=85

The price reduced to 85% the original price, but to find out how much it changed, you have to subtract the part from the whole meaning

100% - 85% = 15%

How long will it take Eniola to save $5,000 if she started with $500 and found a rate of 6.2%? Round to the nearest whole number.

Answers

Answer:

the time period is 38.28 years

Step-by-step explanation:

The computation of the time period is shown below:

Given that

RATE = 6.2%

PV = $500

PMT = $0

FV = $5,000

The formula is shown below:

= NPER(RATE;PMT;-PV;FV;TYPE)

After applying the above formula, the time period is 38.28 years

Hence, in order to save $5,000 it would take 38.28 years

A bag with 5 pound of potatoes costs $3.20. How much do 12 pounds of potatoes cost at the same rate?​

Answers

Answer:

$7.68

Step-by-step explanation:

You must find the rate first, so in order to do that you divide the price by the quantity which is

3.20/5

which equals .64 and this number is the cost of potatoes per pound so to find 12 pounds you do

.64 * 12

which equals 7.68

Answer: 7.68

Step-by-step explanation:

First you find the rate where you do 3.20/5 which equals .64

Then you multiply the 12 and .64 and get 7.68

Given that
X2: (20 – 3x) = 1 : 2
find the possible values of x.​

Answers

Answer:

Step-by-step explanation: x^2 : (20 - 3x) = 1 : 2

2x^2 + 3x - 20 = 0

(x + 4)(2x - 5) = 0

Solution:

x = -4

x = 5/2

Answer:

x= 2.5

x= 2.5x = - 4

Step-by-step explanation:

1:2

x² : (20 - 3x)

x2 : x 1

2x² : 1(20-3x)

2x² : 20 - 3x

+3x , then - 20

2x² + 3x - 20 = 0

2 x - 20 = - 40

x to get - 40

+ to get 3

(8 x - 5 = -40 & 8 + - 5 = 3)

Split 3x into 8x & - 5x, then factorise:

2x^2 + 3x - 20 = 0

2x^2 + 8x - 5x - 20 = 0

2x(x+4) - 5(x + 4)

(2x-5) (x+4) =0

2x - 5 = 0

+5

2x = 5

÷2

x = 2.5

x+4=0

-4

x = - 4

x=2.5,-4

What is the equation of the circle?

Answers

Answer:

x² + y² = 3

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

Using Pythagoras' identity in right triangle CRT

CR² = 1² + ([tex]\sqrt{2}[/tex] )² = 1 + 2 = 3 ( take the square root of both sides )

CR = r = [tex]\sqrt{3}[/tex] , then

x² + y² = ([tex]\sqrt{3}[/tex] )² , that is

x² + y² = 3

find the length of the missing side in the following examples

Answers

Answer: 1. 6.1

2. 13

3. 5.4

4. 5.7

5. 10.4

6. 31

Step-by-step explanation:

I got the values of the missing sides by doing the Pythagorean theoreom. Therefore, I had to find the length of the hypotenuse. a^2+b^2=c^2

a and b are the values of the sides given, and we have to find the value of c. So, for instance on number one 6 and 3 are a b. (6)^2+(3)^2= 45. Now we have to find the square root of 45. The square root of 45 is 6.7082039325.

So the value of the missing side in number one is 6.7.
