Answer:

x = 13, y = 24.

Step-by-step explanation:

5x - 8 + 63 + 7x - 31 = 180  (interior alternate angles are equal).

12x + 24 = 180

12x = 180 - 24 = 156

x = 156/12

x = 13.

4y + 27 =  63 + 7x - 31       (interior alternate angles are equal).

4y +27 = 32 +7(13)

4y = -27 +32 + 91

4y = `96

y = 96/4

y = 24.

A cell phone company charges $300 for a new phone and $40 for a monthly plan. If C (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function?

R: ℝ
R: (0, 300)
R: (40, 340)
R: (–∞, ∞)

Answers

Answer:

The $300 charge will last until the new phone is paid off. After that the monthly charge will be $40 only.

The range of the function will be between $40 and $340:

R:[40, 340]

Correct choice is C

Charge for new phone =$300Charge per month as monthly plan=$40

Now

[tex]\\ \rm\hookrightarrow \mathbb{R}=(x,y)[/tex]

Step-by-step explanation:

-301 = -3x = 7(4x – 18)

-301 = -3x = 28x - 126

-301 = 31x = -126

-175 = 31x

please help! ill give brainlyest! solve the absolute value equation

Answers

Answer:

x = [tex]\frac{40}{9}[/tex] , x = - [tex]\frac{56}{9}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] | [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | - 1 = 1 ( add 1 to both sides )

[tex]\frac{1}{2}[/tex] | [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | = 2 ( divide both sides by [tex]\frac{1}{2}[/tex] )

| [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | = 4

The absolute value always gives a positive result, however, the expression inside can be positive or negative, then

[tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] = 4 ( multiply through by 12 to clear the fractions )

9x + 8 = 48 ( subtract 8 from both sides )

9x = 40 ( divide both sides by 9 )

x = [tex]\frac{40}{9}[/tex]

-------------------------------------------------------

OR

- ([tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] ) = 4 , distribute left side

- [tex]\frac{3}{4}[/tex] x - [tex]\frac{2}{3}[/tex] = 4 ( multiply through by 12 to clear the fractions )

- 9x - 8 = 48 ( add 8 to both sides )

- 9x = 56 ( divide both sides by - 9 )

x = [tex]\frac{56}{-9}[/tex] = - [tex]\frac{56}{9}[/tex]

Please help me with this question, I only need help with c), I already know the others, a) 9pi metres squared, b) 8pi metres squared, and d) 54.5metres squared.

Answers

Answer:

1.06 m²

Step-by-step explanation:

To find the area of the two ends, you need to find the area of the inner circle, then subtract that from the area of the large circle.

As we know, A = πr²

The diameter of the larger circle is 1.8, so the radius is 0.9.

π(0.9)² = 2.54

The diameter of the smaller circle is 1.6, so the radius is 0.8

π(0.8)² = 2.01

2.54 - 2.01 = 0.53 m² (this is for one end)

0.53 x 2 = 1.06 m²

if you will solve this questions in copy and send me pictures of the answer then it will be very helpful for me please​

Answers

500 at 40 each = £20000

To make a profit he needs to make more than £20000

20 broke so he sold 500-20 = 480 at 45 each.

480 x 45 = 21600

Profit = 21600 -20000 = 1600

His profit was £1,600

15 people fit comfortably in a 6 feet by 6 feet area. Use this value to estimate the size o a crowd that is 30 feet deep on both sides of the street along a 2-mile section of a parade route. (Hint: 1mile= 5,280ft)

Answers

158,400 people will fit into an area with a dimension of 30feets by 2 miles.

The area of the street can be calculated thus :

Area = Length × width

Converting the width to feets :

1 mile = 5280 feets

2 miles = x

Cross multiply :

x = 5280 × 2 = 10560 feets

Area = 10560 ft × 30ft = 316800 ft²

Since 15 people fit into an area with dimension which is 6 ft by 6ft

Area = 6 × 6 = 36 ft²

Let x = number of people

15 people = 36 ft²

x people = 316800 ft²

Cross multiply :

x = (316800 × 15) / 36

x = 158,400 people

Hence 158,400 people will fit in.

Since there are 8 girls and 7 boys, the teacher must have two rows of GBGBG and one row of BGBGB. There are three ways to choose this row, and once this is done, every seat is reserved for either a girl or a boy. There are 8! ways to arrange the girls in their seats, and 7! ways to arrange the boys, so the total number of seating arrangements is 3 * 7! * 8!
