A cyclist travels at an average speed of 13 mph for 3 hours.
How far did she travel in miles?

Answers

Answer 1

Answer:

39 miles

Step-by-step explanation:

We know that a cyclist travelled at an average rate of 13 miles per hour for 3 hours and are asked to how far she travelled in miles.

To solve, we need to take into mind that for three hours, the cyclist drove 13 miles per hour.

Meaning that for every hour, 13 miles were driven.

Therefore we need to multiply 13 by 3 to get our answer :

13 miles * 3hrs

39 miles

A salesperson will earn a commission equal to 1/32 of the total sales. what is the commissions earned on the sales totaling 24000 ​

Answers

Answer:

Step-by-step explanation: When dealing with fractions in the way they are used in this problem the word "of" (as in "1/32 OF the total sales") means to multiply.

the total sales") means to multiply.

So we can write an equation as:

c

=

r

⋅

s

Where:

c is the commission earned, what we are solving for in this problem.

r  is the commission rate -  1/

32  in this problem

s  is the total sales - $24,000 in this problem.

Substituting and calculating  c  gives:

c

=1/32 x $24,000

c=$24,000/

For which value of m is start fraction 4 over 16 end frction equals start fraction m over 24 end fraction a proportion? A. m = 6 B. m = 8 C. m = 12 D. m = 14

Answers

Answer:

A. M=6

Step-by-step explanation:

Basically, this question is asking you to find m if 4/16 = m/24.

First, 4/16 can be simplified to 1/4. This will make it easier to solve.

You now have 1/4 = m/24.

Multiply both sides by 24 to get 24/4 = m.

Simplify to get m = 6.

The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?

Answers

Step-by-step explanation:

3(-2m + 5) -6(-4m - 2) =

-6m + 15 + 24m + 12=

18m + 27

18= a 27= b 27 + 18= 45

The value of the expression a + b is 45.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

First, we can simplify the expression using the distributive property:

3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12

Combining like terms, we get:

18m + 27

So, a = 18 and b = 27, which means:

a + b = 18 + 27 = 45

Therefore,

The value of a + b is 45.

A circle is drawn inside a square so its circumference touches each of the four sides of the
square. If the area of the circle is 125.8cm2 calculate the length of the sides of the square.

Answers

Answer:

12.66 cm

Step-by-step explanation:

Area of the circle = 125.8 Sq cm

[tex] \therefore \: \pi {r}^{2} = 125.8 \\ \\ \therefore \: 3.14 \times {r}^{2} = 125.8 \\ \\ {r}^{2} = \frac{125.8}{3.14} \\ \\ {r}^{2} = 40.0636943 \\ \\ {r} = \sqrt{40.0636943} \\ \\ r = 6.32958879 \\ \\ r \approx \: 6.33 \: cm \\ \\ d \: = 2r \\ \\ d = 2 \times 6.33 \\ \\ d = 12.66 \: cm \\ [/tex]

Diameter of the circle = 12.66 cm

Since, circumference of the circle touches each of the four sides of the square.

So, length of the sides of the square

= diameter of the circle.

= 12.66 cm

24 is 3/4% of what number

Answers

24 is 3/4 of the number 32

Answer:

32

Step-by-step explanation:

Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)

So our simple equation looks something like this:

[tex]24= x *\frac{3}{4}[/tex]

So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.

So: [tex]24 * \frac{4}{3} = x[/tex]

Doing the simple math we get:

[tex]24 * \frac{4}{3} = 32[/tex].

32 is your answer.

Hope this helps and have a nice day! Sorry I'm not great at explaining it!

Passage: What Causes Earthquakes Natural earthquakes occur mostly from tectonic movements of the plates. Tectonic plates are large parts of the oceanic and continental lithosphere. The lithosphere is the solid outer section of Earth's crust. These sometimes shift into various positions both under water and above. Such movements generally occur along fault lines. When two rocks slide against each other, they create fault lines. These fault lines can be both extremely narrow or miles wide. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. Movement between the tectonic plates is rarely smooth. When the plates slide against each other, they create a tremendous amount of friction. This friction forms seismic energy that travels in waves through the surface of the Earth. This causes the earthquake. While normal energy travels above the surface of the Earth, seismic energy travels under the Earth's surface. This creates more tension between the land plates, causes more shifting, and creates more fault lines. The spot below the Earth's surface where the rocks break against each other is called the focus of the earthquake. The place exactly above the focus on the surface of the planet is called the epicenter of the earthquake. Sometimes, earthquakes can also be man-made instead of natural. These can sometimes be caused due to explosions underground. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing. But the seismic energy formed due to these explosions is rarely very strong. Therefore, the strength of the earthquakes caused is not very high.Question: In What Causes Earthquakes," which detail supports the idea that friction exists between the plates underground? A. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. B. Movement between the tectonic plates are rarely smooth. C. When two rocks slide against each other, they create fault lines. D. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing.
