Write a multiplication equation and a division equation that can be used to answer how many 3/4's are in 2

Answers

Given:

Two numbers $(3)/(4)$ and 2.

To find:

How many $(3)/(4)'s$ are in 2.

Solution:

Let x be number of $(3)/(4)'s$ in 2.

$(3)/(4)* x=2$

Divide both sides by $(3)/(4)$ .

$x=(2)/((3)/(4))$

$x=2* (4)/(3)$

$x=(8)/(3)$

Therefore, required multiplication equation is $(3)/(4)* x=2$ and the required division equation is $x=(2)/((3)/(4))$ .

An equilateral triangle has an apothem of 5 cm. Find the perimeter of the triangle to the nearest centimeter.

Answers

The apothem is the distance from the center to the midpoint of one of the sides of a regular polygon. You can make a right triangle with the apothem, the line from the midpoint to the corner and the line from the center to the corner. An equilateral triangle has 60 degree angles (180/3). The right triangle has half of one of those angles so 30 degrees. Now we have a 30-60-90 triangle where the short leg is 5cm. The long leg, which is also half of one side of the triangle is thus $5√(3)$ . A whole side of the triangle is $10√(3)$ . Multiply that by 3 to get the perimeter of $30√(3)$ .

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

At a candy store a bag holds up to 1 pound of candy. Each jawbreaker (x) weighs 0.25 pounds and each gumball (y) weighs 0.1 pounds. Which inequality shows the solution for all combinations of the two candies that will fit in the 1-pound bag?

Answers

x - number of jawbreakers;
y - number of gumballs.
The weight of jawbreakers + gumballs must be less than or equal to 1 pound.
Inequality that shows the solution for all combinations of the two candies is:
0.25 x + 0.1 y ≤ 1
