What is the division expression that is the same as 1/5 * 1/4 ?
A. 1/5 divide by 2
B. 1/5 divide by 3
C. 1/5 divide by 4
D. 1/5 divide by 5

Answers

Answer 1

Answer:

C. 1/5 divide by 4

Step-by-step explanation:

When you divide two fractions, you multiply the first fraction by the reciprocal of the other one. To find the reciprocal of the second fraction, yo just have to switch the value of the numerator and denominator (i.e. 4/1's reciprocal is 1/4).

Another important thing to note is that 1/5 x 1/4 is 1/20 because you multiply straight across numerators and denominators.

Now that we have some back ground information, let's which expression leads to 1/20!

A:

1/5 x 2/11/5 x 1/21/10Incorrect Answer Choice

B:

1/5 x 3/11/5 x 1/31/15Incorrect Answer Choice

C:

1/5 x 4/11/5 x 1/41/20Correct Answer Choice!

Therefore, the answer is C. 1/5 divide by 4.

What is the solution to this inequality?

−4x − 8 > −20
Question 7 options:

x > −3

x < −3

x > 3

x <3

Answers

Answer:

[tex]\boxed{\sf{D. \quad x < 3}}[/tex]

Step-by-step explanation:

It is necessary to isolate the term of x from one side of an inequality to find its solution.

-4x-8>-20

First, add by 8 from both sides.

[tex]\sf{-4x-8+8 > -20+8}[/tex]

Solve.

-20+8=-12

Rewrite the problem down.

[tex]\sf{-4x > -12}[/tex]

Multiply by -1 from both sides.

(-4x)(-1)<(-12)(-1)

Solve.

Multiply the numbers from left to right.

(-12)(-1)=12

4x<12

Divide by 4 from both sides.

4x/4<12/4

Solve.


Divide the numbers from left to right.

12/4=3

x<3

Therefore, the correct answer is D. x<3 (last option).

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

Option D.

Why is this the case, though?

These equations prove it true.

[tex]-4 * 2 - 8 = -16 > -20[/tex]

[tex]-4 * 1 - 8 = -12 > -20[/tex]

The only reason these two equations are correct, is because on the number line it shows: Any negative number further to the right than the last negative number is greater than that number.

Dale polled the 2 fastest swimmers on the swim team.

Is this sample of the swimmers on the swim team likely to be representative?

Answer as Yes or No

Answers

Answer:   No

Reason:

Dale is biased toward the two fastest people in the group, but is leaving out the rest of the swimmers who may not be so fast. The people left out may be very distant from the top two swimmers. Therefore, Dale has not picked a representative sample.

As an example with numbers, let's say we had these average speeds in mph: {1, 2, 3, 4, 20, 30}. Of course these are just hypothetical examples and not based on actual realistic speeds; however, the example should still suffice.

That data set shows the average is closer to 2 and 3 than it is to 20 and 30. Dale polling the fastest people greatly skews the mean larger than it should be.

To get a better more representative sample, Dale should randomly pick 2 people regardless if they are the top two swimmers or not. He can pick the names out of a hat, or use a computer program to generate random numbers.

Yes because there the fastest and people would want to be like them

Solve 5x-10=3x+2. Explain.

Answers

Answer:

6

[tex] \: [/tex]

Step-by-step explanation:

It is given an equation and we are to find the value of x.

[tex] \: [/tex]

Given Equation :

[tex] \\ {\longrightarrow \qquad{ \sf{5x-10=3x+2}}} \\ \\ [/tex]

Subtracting 3x from both sides we get :

[tex]\\ {\longrightarrow \qquad{ \sf{5x-10 - 3x=3x - 3x+2}}} \\ \\ [/tex]

[tex] {\longrightarrow \qquad{ \sf{2x-10=2}}} \\ \\ [/tex]

Adding 10 to both sides we get :

[tex] \\ {\longrightarrow \qquad{ \sf{2x-10 + 10=2 + 10}}} \\ \\ [/tex]

[tex] {\longrightarrow \qquad{ \sf{2x=12}}} \\ \\ [/tex]

Dividing both sides by 2 we get :

[tex] \\ {\longrightarrow \qquad{ \sf{ \frac{2x}{2} = \frac{12}{2} }}} \\ \\ [/tex]

[tex] {\longrightarrow \qquad{ \frak{ \pmb{x=6}}}} \\ \\ [/tex]

Therefore,

The value of x is 6.

-10 + 5 + -3 = 2 + 3 + -3

ℭ  : 5 + -3 = 2

-10 + 2 = 2 + 3 + -3

ℭ  : 3 + -3 = 0

-10 + 2 = 2 + 0

-10 + 2 = 2

'10'      .

-10 + 10 + 2 = 2 + 10

ℭ  : -10 + 10 = 0

The asteroids are mostly found in the broad space between Mars and Jupiter, a region of the solar system called the asteroid belt. Asteroids are too small to be seen without a telescope; the first of them was not discovered until the beginning of the nineteenth century.

Discovery and Orbits of the Asteroids

In the late 1700s, many astronomers were hunting for an additional planet they thought should exist in the gap between the orbits of Mars and Jupiter. The Sicilian astronomer Giovanni Piazzi thought he had found this missing planet in 1801, when he discovered the first asteroid (or as it was later called, “minor planet”) orbiting at 2.8 AU from the Sun. His discovery, which he named Ceres, was quickly followed by the detection of three other little planets in similar orbits.

Answer:

The volume is 160

Step-by-step explanation:

Explanation: To find the volume of the rectangular prism you need to multiply 8x20. The reason is because there are 20 cubes in each row (i'm sorry if i'm not good at explaining math very well). The way I found the volume was to count the amount of cubes on the side and multiply it by how many rows there were on top. So that brings me to 160. The product of 8x20. (I hope this helps, math isn't my best subject)

Answer:

V = 160 cubic inches

Given that,

Length, width and height of prism are 8 inches, 4 inches and 5 inches

The formula for the volume of a rectangular prism is given by :
