Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or 3. He rolls the number cube one time

Answers

Answer:

B. 1/3

Step-by-step explanation:

The total number of sides in the cube are 6 (1,2,3,4,5,6). If Dimas only wants to roll either a 2 or 3 then that would mean that he has 2 chances out of the total 6 probable outcomes to roll one of those numbers. Therefore, in order to find the probability of this happening in a single roll we need to divide the number of times that his two choices appear on the dice by the total number of sides the dice has, like so...

2 / 6 = x

If we simplify it would give us [tex]\frac{1}{3}[/tex]

A phone company offers to monthly plans. Plan a cost $23 plus an additional $.08 for each minute of calls. Plan B cost $19 an additional $.12 for each minute of calls.

Answers

Answer:

The indifference point is 100 minutes.

Step-by-step explanation:

Giving the following information:

Plan a cost $23 plus an additional $.08 for each minute of calls.

Plan B cost $19 an additional $.12 for each minute of calls.

First, we need to establish the total cost formula for each plan:

Plan A= 23 + 0.08*x

Plan B= 19 + 0.12*x

x= number of minutes

Now, to calculate the indifference point, we equal both formulas and isolate x:

23 + 0.08x = 19 + 0.12x

4 = 0.04x

100= x

The indifference point is 100 minutes.

Prove:

Plan A= 23 + 0.08*100= $31

Plan B= 19 + 0.12*100= $31

There are 4 birds and 6 snakes. What is the ratio of birds to snakes?

Answers

Answer:

4/6

Step-by-step explanation:

it says birds first so the bird number goes first

The ratio of birds to snakes is 2:3 if there are 4 birds and 6 snakes the answer is 2:3.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

There are 4 birds and 6 snakes.

Number of birds = 4

Number of snakes = 6

The ratio = birds: snakes

= 4: 6

On simplifying:

= 2:3

Thus, the ratio of birds to snakes is 2:3 if there are 4 birds and 6 snakes the answer is 2:3.

Answer:

b.) 350 = 0.25m + 300

Step-by-step explanation:

His earnings are a fixed amount, $300, and a variable amount that depends on the number of miles.

The variable amount depends on the number of miles he drives.

For 1 mile, he earns $0.25

For 2 miles, he earns $0.25 * 2

For m miles, he earns $0.25 * m

The total amount he earns is the fixed amount plus the variable amount

300 + 0.25m or 0.25m + 300

He earned $350, so we get the equation

350 = 0.25m + 300

Answer: b.) 350 = 0.25m + 300

Option 'b' i.e. -11/20 is the correct option.

Thus,

[tex]\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{1}{5}-\frac{3}{4}[/tex]

Determining the difference of the fractions

[tex]\frac{1}{5}-\frac{3}{4}[/tex]

The Least Common Multiplier of 5, 4 is 20. Thus, adjust the fractions based on the L.C.M.

[tex]\frac{1}{5}-\frac{3}{4}=\frac{4}{20}-\frac{15}{20}[/tex]

Apply the fraction rule:  [tex]\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]

          [tex]=\frac{4-15}{20}[/tex]

Add the number: 4-15 = -11

           [tex]=\frac{-11}{20}[/tex]

Apply the fraction rule:  [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]

            [tex]=-\frac{11}{20}[/tex]

Please check the attached figure, where the pointing-down arrow is representing the correct answer which is -11/20.

Therefore, option 'b' i.e. -11/20 is the correct option.

Thus,

[tex]\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}[/tex]

Give a example of force applied to an object that dies not change the objects's velocity.

Answers

Answer:

friction

Step-by-step explanation:

Consider an object that's not moving, like a chair at rest on the floor. There are two forces acting on it:

• its own weight, pulling it downward

• the normal force, i.e. the floor pushing upward on the chair.

Both of these forces are non-vanishing, but the net force is 0, so the chair remains at rest and its velocity stays at 0.

A singer and a producer each wrote songs for an upcoming album. The singer wrote 6 fewer than twice the number of songs that the producer wrote. They wrote a total of 54 songs. How many songs did the singer and producer wrote?

Answers

Answer:

The producer wrote 20 songs

The Singer wrote 34 songs

Step-by-step explanation:

Let

Number of songs the producer wrote = x

Number of songs the singer wrote = 2x - 6

Total songs written by singer and the producer = 54

54 = x + (2x - 6)

54 = x + 2x - 6

54 + 6 = 3x

60 = 3x

Divide both sides by 3

x = 60/3

= 20

x = 20 songs

Number of songs the producer wrote = x = 20 songs

Number of songs the singer wrote = 2x - 6

= 2(20) - 6

= 40 - 6

= 34 songs

The producer wrote 20 songs

The Singer wrote 34 songs

Step-by-step explanation:

Using the slope-intercept equation, a line is given as y=mx+b, where m represents the slope and b represents the y-intercept. From this graph, we can see that the slope is 1/3 and this line meets the y-axis at -4.

Thus, using that information, we substitute this into the equation to get

The Pine Apple Store found that 18% of their weekly customers would purchase a new R-phone before leaving the store. If this was equivalent to 63 customers, how many total people entered the store last week?

Answers

Answer:

350 customers

Step-by-step explanation:

Since this is a ratio question and we only have variable that we need to solve (total people that entered last week), Then we can use the Rule of Three to solve this problem. We do this by multiplying the diagonal values of the following model and dividing by the third value in order to find the variable, like so...

18% of customers  <====>  63 customers

100% of customers  <====>  x customers

(100 * 63) / 18 = x

6,300 / 18 = x

350 = x

Finally, we can see that a total of 350 customers entered the store last week.

Describe and correct the error a student made when graphing the linear equation y=−

4x−6.

Answers

Answer:

In step 1 the y-intercept should be plotted at (0,-6)

Step-by-step explanation:

Remember that to find the Y intercept in any linear equation you need to use 0 as your X value, this means taking the formula in the y=mx+b form and replacing X with a 0.

Since the formula is y = -3/4x -6

We just insert a 0 insted of the "x"

y = -3/4(0) -6

y=0-6

y=6

So the y-intercept sould be placed in (0,-6)

That's what he did wrong when graphing the equation.
