Answer:

$42.49

Step-by-step explanation:

This means the cost of the item to you is $42.49. You will pay $42.49 for a item with original price of $49.99 when discounted 15%. In this example, if you buy an item at $49.99 with 15% discount, you will pay 49.99 - 7.4985 = 42.49 dollars.

Answer:

42.49

Step-by-step explanation:

Discount = 15% of 49.99

              = 0.15 * 49.99

              = 7.4985

Cost after discount = 49. 99 - 7.4985

                               = 42.4915

                               = 42.49

Answer: D

Step-by-step explanation:

If after 5 seconds the height was 20 feet then  in 10 seconds it will be 40 feet  and in 20 seconds it will be 80 seconds.

To get from 5  to 10 you multiply by 2

To get from 20 to 40 you multiply by 2.

Since you have a constant change then it works for D only.

The linear equation that represents the height of the balloon at a time will be y = 4x. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

A hot air balloon is launched from the ground and climbs into the air at a consistent velocity. The balloon's elevation is 20 feet after 5 seconds. The balloon keeps rising at the same rate.

The height per second is given as,

m = 20 / 5

m = 4 ft/sec

Then the equation is given as,

y = 4x

At x = 10 sec, then the value of y will be

y = 4 (10)

y = 40 ft

At x = 20 sec, then the value of y will be

y = 4 (20)

y = 80ft

The linear equation that represents the height of the balloon at a time will be y = 4x. Then the correct option is D.

Answer:

200,000 and 2005 which cant theoretically be done be P(t) which would increase in the population which would most likely be from 2005 to 2020. so you cannot do this because imagine it as X=(Y)x the mass of population which would be defined as (P) which will also be represented as a probable and physical change in the number. but not only the number, but the population. being have of the initial amount which you will take the variable (P) and have the exact amount which would be the population. Which would theoretically recon as a positive ID of the population.-Cj

Answer:

[tex]YZ = 19cm[/tex]

Step-by-step explanation:

To figure out what line YZ equals, we must first find x. And to do this, let's set up an equation.

Firstly, we know that XY is 8cm, and XZ is 4x+3. So, we know that XY + YZ will equal XZ. Let's set that up:

[tex]8 + 2x+7=4x+3[/tex]

Combine like terms.

[tex]2x+15=4x+3[/tex]

Subtract 2x from both sides.

[tex]15=2x+3[/tex]

Subtract 3 from both sides.

[tex]12=2x[/tex]

Divide both sides by 2.

[tex]6=x[/tex]

Now, we just need to plug 6 into the equation of YZ.

[tex]2(6)+7[/tex]

[tex]12+7[/tex]

[tex]YZ = 19[/tex]

Answer:

The difference is 3.97 inches of rainfall

Step-by-step explanation:

Here, we want the difference between the wettest and driest months.

From the question, we can see that the wettest month has a rainfall height of 2.3 inches

The driest month has a rainfall of -1.67 inches

So the difference between the two will be;

2.3 - (-1.67)

= 2.3 + 1.67 = 3.97 inches

Answer:

4.03

Step-by-step explanation:

Have to add 2.36 and 1.67 and it would be a positive.

Answer:

To convert, start by adding both parts of the ratio together. This will be the denominator for each of the fractions and also represents the whole set. Then, each part of the ratio creates a fraction, with the numerator being the first part of the ratio and the denominator being the sum that was just found.

[tex]x + (x - 86) = 90[/tex]

[tex]2x - 86 = 90[/tex]

Both sides plus 86

[tex]2x = 90 + 86[/tex]

[tex]2x = 176[/tex]

Divided both sides by 2

[tex]x = \frac{176}{2} \\ [/tex]

[tex]x = 88[/tex]

So the angles are :

[tex]88 \: \: \: \: \: and \: \: \: \: 2[/tex]

The measure of the two complementary angles are 88° and 2°.

"When the sum of two angles is 90°, then the angles are known as complementary angles."

Let, the complementary angle of the mentioned angle is x.

Therefore, the angle is = (x - 86°)

Now, x + (x - 86°) = 90°

⇒ 2x - 86° = 90°

⇒ 2x = 176°

⇒ x = 88°

Therefore, the measured angle is 88°.

It's complementary angle is = (90° - 88°) = 2°.

Answer:

1.0014 Miles

Step-by-step explanation:

The light travels at 186,291 miles per second (~300,000 km/s), and speed of sound in dry air is equal to 0.21 - 0.22 miles per second (0.33-0.35 km/s), as it varies with the temperature. We can notice the lightning almost immediately even though the storm is far from us, but the thunder needs around 5 seconds to travel one mile and approximately 3 seconds to travel one kilometer. Thanks to this seven orders of magnitude difference in sound and light propagation, we can easily estimate the storm distance
