Erinn's basic cell phone plan charges
$54.99 for service plus $0.18 per minute
beyond the included 500 minutes in the
plan.
How much will it cost Erin if she used her cell phones home for 570 minutes in one month?

Answer:

Step-by-step explanation:

10% discount means you pay 90% of the original cost x.

90% of x = $40.50

0.90x = $40.50

x = $40.50/0.90 = $45

:::::

total cost = 1.065·$40.50 ≅ $43.13

Answer:

2) 68°

Step-by-step explanation:

The required answer is 68°

Answer:

We have the equation:

x - y = 4

We can write this as a linear equation in the slope-intercept form if we isolate the variable y.

We get:

y = x - 4

Now to graph this function, we need to evaluate x in two different points and get two points (x, y) of the line.

If we use x = 1 and x = 2, then we get:

y(1) = 1 - 4 = - 3

Then we have the point (1, -3)

and:

y(2) = 2 - 4 = - 2

Then we have the point (2, - 4)

Now we need to draw these two points in the coordinate axis, and draw a line that connects the points, the example can be seen in the image below.

a) To use the graph, we need to locate the value x= 7 in the x-axis.

Then draw a vertical line

In the point where the vertical line intersects the graph, we draw an horizontal line.

The y-value will be the value at which this horizontal line intersects the y-axis

In this case, is at  y = 3.

Then when x = 7, y = 3.

(you can see it in the graph)

ii) The coordinate at which the graph intersects the x-axis can be seen in the graph, it is the point (0, 4)

Answer: 1 guppy = 3 goldfish

1 goldfish = 2 betta fish.....so 3 goldfish = (3 * 2) = 6 betta fish

1 betta fish = 2 angel fish....so 6 beta fish = (6 * 2) = 12 angel fish

so the number of angelfish that can be formed by 1 guppy is 12 angelfish

Answer:

A = 18[tex]\sqrt{3}[/tex] sq meters

Step-by-step explanation:

find BD, can use altitute rule:

3 / BD = BD / 9

BD² = 27

BD = [tex]\sqrt{27}[/tex] = 3[tex]\sqrt{3}[/tex]

Area of ΔABC = 1/2 · (3+9) · 3[tex]\sqrt{3}[/tex]

A = 6 · 3[tex]\sqrt{3}[/tex]

i think 2 bags or 1 bags hope it helps

The area of the farmer's land is 54 square yards and number of bags needed is 2. The correct option is (B).

A triangle is a two dimensional shape bound by three sides. The sum of the interior angles of a triangle is 180°. The longest side of a triangle is always less than the sum of other two sides.

For the given diagram, the following data is given as,

Base of the upper and lower triangle is 6.5 + 2.5 = 9 yards.

And, the height is given as 6 yards.

Now, the area of the land can be given as,

Area of upper triangle + Area of lower triangle

⇒ 1/2 × 9 × 6 +  1/2 × 9 × 6

⇒ 54 square yards.

As per the question, the area of the land is more than the soil contained in 1 bag.

Which implies the number of bags required is given as 2.

Hence, the area of land and number of bags required is obtained as  54 square yards and 2 respectively.

Answer:

  an = n + 1

Step-by-step explanation:

This arithmetic sequence has a first term of 2 and a common difference of ...

  3 - 2 = 1

The general term is ...

  an = a1 + d(n-1)

Using a1=2 and d=1, this is ...

  an = 2 +1(n -1)

  an = 2 + n - 1 . . . . . eliminate parentheses

  an = n + 1 . . . . . . . .collect terms

Answer: 72 Miles In 90 Minutes

Step-by-step explanation: First, you have to divide both 15 & 12 by 15, (which represents minutes), and you get 1 over 0.8. Next, you multiply 1 over 0.8 times 90, which gibes you 90/72. There is your answer! I hope that you found this helpful.

Here is the equation below:

15/12 divided by 15/15 = 1/0.8 x 90/90 = 90 MINUTES/72MILES

Answer:

y = 2/5x - 1

Step-by-step explanation:

There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.
