(no answer choices)

Answers

Answer 1

Answer:

x=9

Step-by-step explanation:

-2x+6=x-3

-1x+6=-3

-1x=-9

divide both sides by -1

x=9

hope this helps

Answer 2

Answer:

(3, 0)

Step-by-step explanation:

Given system:

y = x – 3 and y = –2x + 6

Substitute y and solve for x:

x - 3 = -2x + 6x + 2x = 6 + 33x = 9x = 3

Find y:

y = x - 3 = 3 - 3 = 0

Solution is:

(3, 0)

A rectangular box is 40 cm wide and 36 cm high. If the surface area of the box is 7440 square centimeters, find the length of the box.

Answers

Answer:

The length of the rectangular box is 30 centimeters.

Step-by-step explanation:

Let suppose that rectangular box is closed. The rectangular box is represented by a parallelepiped, whose surface area ([tex]A_{s}[/tex]), measured in square centimeters, is defined by the following formula:

[tex]A_{s} = 2\cdot (w\cdot h + w\cdot l + h\cdot l)[/tex] (1)

Where:

[tex]w[/tex] - Width, measured in centimeters.

[tex]h[/tex] - Height, measured in centimeters.

[tex]l[/tex] - Length, measured in centimeters.

If we know that [tex]A_{s} = 7440\,cm^{2}[/tex], [tex]w = 40\,cm[/tex] and [tex]h = 36\,cm[/tex], then the length of the rectangular box is:

[tex]2880 +80\cdot l + 72\cdot l = 7440[/tex]

[tex]152\cdot l = 4560[/tex]

[tex]l = 30\,cm[/tex]

The length of the rectangular box is 30 centimeters.

https://brainly.com/question/2574086

Answer:

B

Step-by-step explanation:

Given two points, the equation of the line may be determined by,

                           y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)

Substituting the given values,

                               y - 7 = ((9 - 7) / (6 - 3))(x - 3)

Simplification will yield to an answer of,

                                    y = 2x/3 +5

Thus, the answer is the second choice.

Question 5

We get n=42.15 and o=71.5

Question 6

We get e=15.32 and t=17.88

Step-by-step explanation:

Question 5

The triangles are similar.

So, the ratio of corresponding sides will be similar.

[tex]\frac{53}{n}=\frac{88}{70}=\frac{90}{o}[/tex]

First we will solve [tex]\frac{53}{n}=\frac{88}{70}[/tex] to find value of n.

Cross multiply

[tex]53*70=88*n\\n=\frac{3710}{88}\\n=42.15\\[/tex]

Now, we will solve [tex]\frac{88}{70}=\frac{90}{o}[/tex] to find value of o

[tex]88*o = 90*70\\o=\frac{6300}{88}\\o=71.5\\[/tex]

So, We get n=42.15 and o=71.5

Question 6

The triangles are similar.

So, the ratio of corresponding sides will be similar.

[tex]\frac{9.6}{e}=\frac{5.7}{9.1}=\frac{11.2}{t}[/tex]

First we will solve [tex]\frac{9.6}{e}=\frac{5.7}{9.1}[/tex] to find value of n.

Cross multiply

[tex]9.1*9.6=e*5.7\\e=\frac{87.36}{5.7}\\e=15.32\\[/tex]

Now, we will solve [tex]\frac{5.7}{9.1}=\frac{11.2}{t}[/tex] to find value of o

[tex]5.7*t = 11.2*9.1\\t=\frac{101.92}{5.7}\\t=17.88\\[/tex]

So, We get e=15.32 and t=17.88

Answers

Complete question :

Sam knows that his MP3 player has 40% of its battery life left and that the battery

charges by an additional 12 percentage points every 15 minutes. What percent of

the mp3's battery will be charged when Sam and his family leave? If mp3 was plugged in an hour before his family plan to leave.

Answer:

88%

Step-by-step explanation:

Time before leaving = 1hour

Current percentage = 40%

Charge rate = 12% every 15 minutes

Therefore,

Charge rate per minute :

12% / 15 = 0.8% per minute

Charge recieved after one hour (60 minutes) :

0.8% * 60

= 48%

Therefore, total charge after just before leaving is:

Current percentage + percentage received

40% + 48%

= 88%
