Two numbers add to 218. The first is 47 less than the second. What are the numbers

Firlakuza [10]

Defining variables
let n1 be the first number
n2 be the 2nd number

add them together, you get 218
n1+n2 =218

n1 is 47 less than n2
n1=n2-47

do some substitution
n2-47 +n2 = 218

solve for n2

then use n2 to figure out n1

What is the maximum value of P = 24x + 30y, given the constraints on x and y listed below? 120 132 138 150

Marina CMI [18]

Answer:

So the maximum value of P is 138.

Step-by-step explanation:

P(0,0)= 24(0) + 30(0) =0

P(0,1)= 24(0) + 30(1) =30

P(5,0)= 24(5) + 30(0) =120

P(2,3) =24(2) + 30(3) = 138

I also attached the graph images and constraints image as well so according to this is answer for this question, and i hope you got the idea thanks.

A piece of licorice is to be cut into 10 equal-size pieces.If the length of the piece of licorice is 2/3 yard, how long will eac

Eddi Din [679]

Answer:

1/15 yard.

Step-by-step explanation:

I got this by dividing the whole 2/3 of licorice with 10 pieces to get 2/30 (2/3 divided by 10, which eventually becomes 2/3 multiplied by 1/10 to equal 2/30). Then, you simplify it to 1/15. So, each piece would be 1/15 of a yard long.

You are Looking at two area rugs for your bedroom. One is a square with a side length of 6.3 feet the other is rectangle that is

Ray Of Light [21]

Answer:

Part a) The square rug cover the greater area

Part b) The square rug cover 0.33 square feet more than the rectangular rug

Step-by-step explanation:

step 1

Find the area of the square rug

The area of a square is

$A=b^2$

where

b is the length of the square

we have

$b=6.3\ ft$

substitute

$A=(6.3)^2=39.69\ ft^2$

step 2

Find the area of the rectangular rug

The area of the rectangle is

$A=LW$

we have

$L=4.8\ ft\\W=8.2\ ft$

substitute

$A=4.8(8.2)=39.36\ ft^2$

step 3

Compare the areas

$39.69 > 39.36$

The square rug cover the greater area

step 4

Find the difference

$39.69-39.36=0.33\ ft^2$

The square rug cover 0.33 square feet more than the rectangular rug

Why we have exactly six trignomeric

const2013 [10]

A triangle has three sides. A ratio is a comparison of two things. We pick two different sides of the triangle to compare (because there is not much point in comparing one thing to itself). How many ways are there to do this? The first choice has 3 options, and the second has 2, so we have a total of $3\times2=6$ possibilities.
