unit price—- a long distance phone charge of $1.40 for 10 minutes, or $4.50 for 45 minutes —- show work^

Answers

Final answer:

To find the best long-distance phone charge, the unit prices for both options are calculated. The $1.40 charge for 10 minutes has a unit price of $0.14 per minute, while the $4.50 charge for 45 minutes is $0.10 per minute. Hence, the $4.50 option is better.

Explanation:

To determine the better long-distance phone charge, we can calculate the unit price for each option by dividing the total cost by the number of minutes.

For the $1.40 charge for 10 minutes:
Unit Price = Total Cost / Total Minutes
Unit Price = $1.40 / 10 minutes = $0.14 per minuteFor the $4.50 charge for 45 minutes:
Unit Price = Total Cost / Total Minutes
Unit Price = $4.50 / 45 minutes = $0.10 per minute

Comparing the two unit prices, the charge of $0.10 per minute for 45 minutes is the better option since the cost per minute is lower.

How do you do this simultaneous equation?

Answers

The y is the same for both equations. Equate them
-x - 5 = 2x + 4 Add x to both sides
- 5 = 3x + 4 Subtract 4 from both sides.
- 9 = 3x Divide by 3
x = -9 / 3
x = - 3

y = - x - 5
y = -(-3) - 5
y = - 2

So that point is where the two equations meet.

A scale drawing of a rose is 3 inches long. The actual rose is 1.5 feet long. What is the scale factor of the drawing and what is the scale of the drawing? Please explain!! :D

Answers

so 1.5x=3
so, 3/1.5 is 2. since the rose (preimage) is smaller then the image, it is 2 because 1.5×2 is 3.

Answer:

The scale of the drawing is 6

Step-by-step explanation:

Given

Actual Length of Rose = 1.5 feet

Scale drawing of rose = 3 inches

First, we need to equalize both units (by converting feet to inches or inches to feet)

Convert the actual length of rose to inches

If 1 foot = 12 inches

Then 1.5 feet =  12 * 1.5 inches

1.5 feet = 18 inches

Now that we have a single unit for both measurement;

Using the scale factor formula

y = Cx,

where C is the scale factor for x.

y is the measurement of the actual rose = 18 inches

x is the scale drawing of the rose = 3 inches

By substitution; y = Cx,  becomes

18 inches = C * 3 inches --- Make C the subject of formula

C = 18 inches / 3 inches

C = 6

Hence, the scale of the drawing is 6

A fabric store sells two types of ribbon. One customer buys 3 rolls of the satin ribbon and had a total of 120 yards of ribbon. Another customer buys 2 rolls of lace ribbon and 4 rolls of the satin ribbon and has a total of 160 yards of ribbon. How many yards are on one rolls and one roll of satin ribbon?

Answers

Let [tex]x[/tex] be the yards in the satin ribbon roll and [tex]y[/tex] the yards in the lace ribbon roll.

Since 3 rolls of the satin ribbon are 120 yards, [tex]3x=120[/tex]. We can solve the equation to get the yards in one satin ribbon roll like follows:
[tex]3x=120[/tex]
[tex]x= \frac{120}{3} [/tex]
[tex]x=40[/tex]

Now that we know the yards in one roll of satin ribbon, lets find the yards in the lace ribbon one:
Since  2 rolls of lace ribbon and 4 rolls of the satin ribbon are 160 yards, [tex]2x+4y=160[/tex]. But remember that we already know the value of [tex]x[/tex] is 40, so lets replace that in our equation and solve for [tex]y[/tex] to get the yards in one roll of lace ribbon:
[tex]2x+4y=160[/tex]
[tex]2(40)+4y=160[/tex]
[tex]80+4y=160[/tex]
[tex]4y=160-80[/tex]
[tex]4y=80[/tex]
[tex]y= \frac{80}{4} [/tex]
[tex]y=20[/tex]

We can conclude that there are 40 yards in the roll of satin ribbon, and 20 yards in the roll of lace ribbon.

Answer:

d.there are 20 yards on one roll of lace ribbon and 30 yards on a roll of satin

One jug of plant food treats an area of 135 square ft. How many jugs Would be needed to treat an area of 165 square yards (try writing equation)

Answers

Final answer:

To treat an area of 165 square yards, you would need 11 jugs of plant food.

Explanation:

To find out how many jugs would be needed to treat an area of 165 square yards, we need to convert the area to square feet and then divide by the area treated by one jug of plant food.

1 square yard = 9 square feet, so 165 square yards = 165 × 9 = 1485 square feet.

Now, since one jug treats an area of 135 square feet, the number of jugs needed is 1485 ÷ 135 = 11 jugs.

Determine the circumference of a circle with a radius of 4 units.
16 units
8 units
32 units
4 units

Answers

Final answer:

The circumference of a circle with a radius of 4 units can be calculated using the formula C = 2πr, which equals approximately 25.13 units when using π as 3.14159.

Explanation:

To determine the circumference of a circle with a radius of 4 units, we need to use the circumference formula:

C = 2πr

Where C represents the circumference, π (pi) is approximately 3.14159, and r is the radius of the circle.

π is a special mathematical constant that represents the ratio of the circumference of any circle to its diameter, and for most practical calculations, it can be approximated as 3.14. Therefore, plugging the radius (4 units) into the formula we get:

C = 2 x 3.14159 x 4

C = 8 x 3.14159

C = 25.13272 units

We can round this answer to two decimal places for simplicity, obtaining:

C = 25.13 units

So, the circumference of a circle with a radius of 4 units is approximately 25.13 units.

Final answer:

The circumference of a circle with a radius of 4 units is approximately 25.12 units.

Explanation:

The circumference of a circle can be found using the formula C = 2πr, where C is the circumference and r is the radius. In this case, the radius is given as 4 units, so we can substitute that value into the formula to find the circumference.

C = 2π(4) = 8π units.

Since π is approximately 3.14, we can approximate the circumference as:

C ≈ 8 x 3.14 = 25.12 units.

Therefore, the circumference of the circle with a radius of 4 units is approximately 25.12 units.

The width is 6 feet and the length is 14 feet (6+8=14)

Answer:

breath = 6ft

length = 14ft

Step-by-step explanation:

Area of a rectangle = length x breath

Area = 84ft²

Since length is 8feet more than breath.

Let assume a breath is y.

i.e

breath = y

length = y + 8

Area = 84

84 = y * (y+8)

84 = y² + 8y

y² + 8y - 84 = 0

quadratic equation

y ( y - 6 ) + 14 ( y - 6 )

(y + 14 )( y - 6 )

So to find y

y + 14 = 0

y = -14

Or

y - 6 = 0

y = 6

We will you the positive value of y, because we can not have a negative value for measurements ( length or breath)

Therefore

breath = y

breath = 6ft

length = y + 8

length = 6 + 8 = 14ft

Hope it helps! :)

Susan's art class is 540 minutes long. Frank drinks 3 cups of milk a day. The cook needs 2 pints of vegetable broth for their recipe. The coral reef grew 9 meters taller.

To solve these measurement conversion problems, we'll work through each one step by step:

Susan's art class is 9 hours long. Since there are 60 minutes in an hour, her class is 9 hours × 60 minutes/hour = 540 minutes long.To convert Frank's milk consumption from pints to cups, we use the fact that 1 pint is equal to 2 cups. So, 1 ¹/₂ pints is the same as 1.5  × 2 cups, which equals 3 cups.When converting the 4 cups of vegetable broth to pints, we remember that 2 cups is equivalent to 1 pint. Therefore, 4 cups is equal to 2 pints.The coral reef grew by 9000 millimeters. To find this growth in meters, we use the conversion that 1000 millimeters is equal to 1 meter. Therefore, it grew by 9000 mm × (1 m / 1000 mm) = 9 meters.

What is right angle triangle property?

In a right angle triangle, the ratio of the opposite side to the adjacent side is equal the tangent angle between the adjacent side and hypotenuse side.

[tex]\tan\theta=\dfrac{b}{a}[/tex]

Here, (a) is the adjacent side, (b) is the opposite side.

Let the height of the blimp from the ground is y ft and the length of the ground to the Libby's position is x ft shown in the attached image below.

As the angle made by the Libby at the height of the blimp is 43 degrees. Therefore,

[tex]\tan43=\dfrac{y}{x}\\x=1.0724y[/tex]          ......1

Here, Jay is mowing the lawn approximately 2,500 feet (ft) from Libby when they both see the blimp.

Answers

It is 0.5.97 as u know triangle equals to square so g5.0 is the equation for this and divide by square that is ur answer

Answer: Cube is 11 inches tall

Explanation:

Cube has all edges the same length . The volume of a cube is multiplying the length of any edge, height and width of the cube.

Volume of cube = length * width * height

We know that length = width = height = s

So, Volume of cube = s*s*s

= s³

In given question:

Volume of the cube = 1331 cu in.

s³ = 1331

take cube root both the side

s = ∛1331

s = ∛(11*11*11)

s = 11 inch

So, height of the cube = 11 inches
