Then you divide this by $1.20 that is the price of 1 lb of gala apples and you get 2 that is the number of lb of gala apples you can buy.

saidhari bought a toaster oven for $75 this price was 1/4 off the list price. what was the list price

Answers

The total price would have to be $300 , only because if you find the recipocal of 1/4 which is (4) you multiply it by the cost you bought it at which is $75 . So you get $300.

Final answer:

The list price of the toaster oven is $100.

Explanation:

To calculate the list price of the toaster oven, we need to find the original price before the 1/4 discount. Let's represent the list price as 'x'. Since the sale price is $75 and it is 1/4 off the list price, we can set up the equation: x - (1/4)x = $75. Simplifying this equation, we have: 3/4x = $75. To solve for x, we multiply both sides of the equation by the reciprocal of 3/4, which is 4/3: x = $75 × 4/3. Therefore, the list price of the toaster oven is $100.

a model car has a scale of 3 cm : 2 m. The length of the actual hood of the car is 1 m. What is the length of the model?

Answers

1.5 cm is the length of the model.

What is multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

a model car has a scale of 3 cm : 2 m.

The length of the actual hood of the car is 1 m.

Now,

Set up a proportion:

3cm/2m = x/1m

Cross-multiply:

2x=3

Divide by 2:

x=1.5 cm

Hence, 1.5 cm is the length of the model.

The distance from Earth to the Moon is approximately 240,000 mi.. The speed of light is 3.00 * 10^8 m/s. How long does it take for light to travel from Earth to the Moon and back again?. Please Show work.

Answers

First we have to convert miles to meters:
1 mile ≈ 1,609.34 m
Time of traveling one way:
$t = (240,000 * 1,609.34m)/(3.00*10^(8)m/s ) = \n = (8*10 ^(4) *1,609.34s)/(10 ^(8) ) = (8*1,609.34 s)/(10,000)$ = 1.28 s
From Earth to the Moon and back time is: 2 · 1.28 s = 2.56 s

OMG CAN SOMEBODY PLEASE HELP ME PLLLLLLLLLLLSSS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Graduate Management Aptitude Test (GMAT) scores are widely used by graduate schools of business as an entrance requirement. Suppose that in one particular year, the mean score for the GMAT was 476, with a standard deviation of 107.

What values are two standard deviations above and below the mean?

Answers

So we want to start at 476. Then subtract and add 107 to find the standard deviation increments above and below.
476-107=369
369-107=199
199-107=29

The values that are two standard deviations above and below the mean are 690 and 262, respectively

How to determine the values?

The given parameters are:

Mean = 476

Standard deviation = 107

The values above and below the mean are calculated using:

$x = \bar x \pm n\sigma$

In this case n =2.

So, we have:

$x = \bar x \pm 2\sigma$

The value above is:

x = 476 + 2 * 107 = 690

The value below is:

x = 476 - 2 * 107 = 262

Hence, the values that are two standard deviations above and below the mean are 690 and 262, respectively
