Write a simplified expression that represents the perimeter of the rectangle.

Answer:

let x be cost of a hotdog

let y be cost of hamburger

so,

5x + 4y = 17.75                    eq. 1

4x + 5y = 18.25                    eq. 2

manipulate eq. 1 so solve for x:

5x = 17.75 - 4y

x = 17.75/5 - (4/5)y

x = 3.55 - (4/5)y                  eq. 3

substitute eq. 3 to eq. 2:

4(3.55 - (4/5)y) + 5y = 18.25

14.2 - (16/5)y + 5y = 18.25

14.2 + (9/5)y = 18.25

(9/5)y = 18.25 - 14.2

4.05= (9/5)y

y = 2.25

x = 3.55 - (4/5)(2.25)

x = 1.75

hotdog costs $1.75

hamburger costs $2.25

Answer:

400

Step-by-step explanation:

Tge 6 in the tens place is greater than 5, so you round the 3 up to 4.

If the number that determines where you round is 5 or more, round up.

So 366 rounded to the hundreds place is 400.

The answer is 400.

Answer:

4.121216129m

Step-by-step explanation:

use sohcahtoa

tan(70) x 1.5m = 4.121216129m

The height of the tree is 4.12 m.

Given,

I put a ladder 1.5m away from a tree.

The ladder is inclined at 70 degrees about the horizontal.

We need to find out what is the height of the tree.

It is given by:

Tan Ф = Perpendicular / Base

Draw a figure of the given statement.

                       /   | A

                  /        |

(ladder) /             | (tree)

         /.                |

     /.                    |

C /_70°_______ | B  

<--------1.5m-------->              

Find the AB.

AB = height of the tree.

TanФ = AB / CB

Tan 70° = AB / 1.5m

2.7474 = AB / 1.5m

AB = 2.7474 x 1.5m

AB = 4.12 m

Thus the height of the tree is 4.12 m.

Step-by-step explanation:

The percentage decrease in basketball participation from 2013-2014 to 2014-2015 is  0.35%.

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given information in the question,

Number of basketball participants in 2013-2014 = 974,398

Number of basketball participants in 2014-2015 = 970,983

Then, the percentage decrease in the participants,

% decrease = (974,398 - 970,983)/ 974,398 × 100

% decrease = 0.35%.

Answer:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

Step-by-step explanation:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

4/9 is basically obtained when we multiply the denominator of 2/3 by 2 and denominator by 3, which is wrong.

Thus, the correction is as follows:

Given the fraction

[tex]\frac{2}{3}[/tex]

Multiply the nominator and denominator of the fraction by 2

[tex]\frac{2\times 2}{3\times 2}=\frac{4}{6}[/tex]

Thus, the 4/6 is the correct equivalent expression of 2/3.

Answer:

You can sell at least 40 phones each week.

Step-by-step explanation:

Given that:

Weekly base salary = $150

Earning on each phone = $20

Maximum amount that can be earned each week = $950

Let,

m be the number of phones.

20m + 150 ≤ 950

20m ≤ 950 - 150

20m ≤ 800

Dividing both sides by 20

[tex]\frac{20m}{20}\leq \frac{800}{20}[/tex]

m ≤ 40

Hence,

You can sell at least 40 phones each week.

Step-by-step explanation:

Answer:

14,275

1013

Step-by-step explanation:

1: To get the population in the year 2001 we would have to multiply 4500 by 1.08. To get the population in 2002 we would have to multiply: 4500(1.08)(1.08) or 4500(1.08)^2  

Therefore you can write the following equation

4500(1.08)ⁿ where n is the number of years

we need is in 2015 and so n=15 so we have

4500(1.08)¹⁵=14274.5 which you should probably round to 14275

The second one is very similar to the first

to get from 1990 to 1991 you would multiply 5000*.93

so our equation would be

5000(.93)ⁿ where n is the number of years

1990-2012 is 22 so we have

5000(.93)²²=1012.96 which rounds to 1013

For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)

#9-Step by step

Q=25[tex]\pi[/tex]h

divide 25[tex]\pi[/tex] on both sides of the equation

Q/25[tex]\pi[/tex]=h

h=Q/25[tex]\pi[/tex]

Since his can't be simplified any further this is your answer

#11. y=7m+6

First subtract 6 over to the other side

y-6=7m

then divide the 7 over

(y-6)/7=m

m=(y-6)/7

#13 A=(Z+7)3

Divide the three over to the other side of the equation

A/3=Z+7

Now the 7 is free to be subtracted from both sides

(A/3)-7=Z

#17. (2x/5)-9=6

First add 9 to both sides

2x/5=6+9

2x/5=15

Multiply both sides of the equation by 5

2x=5(15)

2x=75

Divide by 2

x=75/2

x=37.5
