Answer:

8 miles

Step-by-step explanation:

If Karen ran 4 miles and walked 5 the fraction for that is 4/5 and if you double both of those you get 8/10 we know that she walked 10 miles so she had to have run 8 miles.

Answer:

8

Step-by-step explanation:

[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

$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

Step-by-step explanation:

−9≥−8(1+6v)−1

Step 1: Simplify both sides of the inequality.

−9≥−48v−9

Step 2: Flip the equation.

−48v−9≤−9

Step 3: Add 9 to both sides.

−48v−9+9≤−9+9

−48v≤0

Step 4: Divide both sides by -48.

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:

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.

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.
