Paloma added a garden to her painting. She has 12 rows of flowers. Each row has 13 plants in it. Each plant has 15 flowers on it. How many flowers are in Palomas garden?

Answers

Answer: 2340 flowers

Step-by-step explanation:

From the question, Paloma added a garden to her painting. She has 12 rows of flowers and each row has 13 plants in it while each plant has 15 flowers on it. To calculate the number of flowers in Palomas garden, we multiply the number of rows by the total number of plants and the number of flowers in each plant. This will be:

= 12 × 13 × 15

= 2340 flowers

Twice a certain number is 44. What is the number?
equation:
n=

Answers

2n = 44
n = 22 (Divide by 2)

Hope I helped.
equation: n = 2n = 44
To work this out, do the opposite of multiplication on both sides of the equation.
This means: 
2n/2 = 44/2

^ a rule is, what you do to one side, you must do to the other. 

This leaves you with n = 22. 

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

If you want to find how the graphs of the functions for the two months are similar and how they are different, here is the answer:

Both are straight lines. 
Both slopes are the same. 
The x and y intercepts are different.

Hope that helps :)

Answer: y = -2/3x + 490

Step-by-step explanation:

2x +3y = 1470  

Slope intercept form definition: y = mx + b is the slope-intercept form of a line where m is the slope and b is the y-intercept.

2x + 3y = 1470

2x + 3y -2x = 1470 - 2x - Subtract 2x from both sides

3y = 1470 - 2x - Simplify

3y/3 = 1470/3 - 2x/3 - Divide both sides by 3

y = -2/3x + 490 - Simplify

-⅔ is the slope and 490 is the y-intercept

in japan, farmers have created watermelons in the shape of rectangular prisms. find the volume of a prism-shaped watermelon in cubic inches if its length is 10 inches, its width is 2/3 foot, and its height is 9 inches

Answers

Given:
rectangular prism.
length = 10 inches
width = 2/3 foot
height = 9 inches

convert width from foot to inches. 1 foot = 12 inches
2/3 foot * 12inches/ft = 2/3 * 12 inches = 2*12/3 = 24/3 = 8 inches

Volume of rectangular prism = length * width * height
V = 10 inches * 8 inches * 9 inches
V = 720 in³
