5n^3-230=90

Answers

Answer 1
Hello!

The equation to solve:

[tex] 5n^{3} -230 = 90[/tex]

To get all the constants on one side, add 230 to both sides:

[tex] 5n^{3} -230 = 90[/tex]
[tex] 5n^{3} - 230 + 230 = 90 +230[/tex]
[tex]5n^{3} = 320[/tex]

Next, divide both sides by 5 to eliminate the coefficient:

[tex]5n^{3} = 320[/tex]
[tex] \frac{ 5n^{3} }{5} = \frac{320}{5} [/tex]
[tex] n^{3} = 64[/tex]

Lastly, take the cube root of each side (or raise each side to the 1/3 power) to isolate n:

[tex] n^{3} = 64[/tex]
[tex] \sqrt[3]{ n^{3} } = \sqrt[3]{64} [/tex]
[tex] n = 4[/tex]

Answer:
n = 4

Is rolling doubles a simple event or compound event? Explain.

Answers

You have to consider the sample space. In this example the sample space 
is {1,2,3,4,5,6}
A simple event can be defined as a SINGLE outcome : Example getting a 3 OR 5 OR any other number from the sample space.
Now if you roll 1 dice & you want to get an even number (2,4,6) then you have chosen from the sample space 3 outcome & this is a compound event
Equally if you roll 2 dice and want to get "one" and/or "three" this is a compound event since you have chosen 2 outcome from the sample space.
Mind you, if you want 5 And 5 when rolling two dice it's a simple event because you have chosen ONE outcome from the sample space.
Hope this will help you to understand this kind of problem

Peach juice and mango juice were mixed in a ratio of 6 to 4 to make tropical punch. A tape diagram representing the ratio of peach juice to mango juice is shown

Answers

the ratio of peach juice to mango juice is 3/2 :
because 6/4 can be reduced to 3/2 by canceling two from the fraction.

The total quantity of the tropical punch in terms of cups is 60 units.

How to get the total quantity

Let P represent the volume of peach juice and M represent the volume of mango juice in the tropical punch.

Given the ratio of Peach : Mango is 6:4, which simplifies to 3:2:

This can be mathematically represented as:

[tex]\( \frac{P}{M} = \frac{3}{2} \) or \( P = \frac{3}{2}M \)[/tex]

In this ratio:

- The volume of peach juice contributes 3 units out of a total of 5 units (3 units peach : 2 units mango) of the tropical punch.

- The volume of mango juice contributes 2 units out of a total of 5 units (3 units peach : 2 units mango) of the tropical punch.

1 unit of the mixture = 12 cups

Therefore, 5 units of the mixture = 5 * 12 = 60 cups

Hence, the total quantity of the tropical punch in terms of cups is 60 units.

Answers

You would change the denominator and get the lowest common denominator. Thos would be 30. You would do 11/6 x 5/5 = 55/30. Then do 3/5 x 6/6 = 18/30. Then add 55/30 + 18/30 = 73/30 and simplify.
Find the least common denominator
6 and 5 least common factor is 30
So multiply each number to get 30

11/6 x5 = 55/30

3/5x6= 18/30

55/30+18/30 = 68/30

Today, the great Pyramid of Giza bear Cario, Eygpt, stands 137 meters tall, coming to a point . A base is a square with each side measuring 230 meters wide. What is the slope of the pyramid

Answers

The correct answer is [tex]1.191[/tex]

To find the slope of the pyramid, we need to calculate the ratio of the vertical change (height) to the horizontal change (half of the base length).

Given information:

- Height of the pyramid (vertical change) = 137 meters

- Base length of the pyramid = 230 meters

- The base of the pyramid is a square, so each side is 230 meters wide

Step 1: Calculate the horizontal change, which is half of the base length.

Horizontal change = [tex]\frac{1}{2} \times Base length[/tex]

Horizontal change = [tex]\frac{1}{2} \times 230 meters[/tex]

Horizontal change = 115 meters

Step 2: Calculate the slope by dividing the vertical change (height) by the horizontal change.

Slope =[tex]\frac{\text{Vertical change}}{\text{Horizontal change}}[/tex]

Slope = [tex]\frac{137}{115}[/tex]

Slope = [tex]{1.191}[/tex]

Therefore, the slope of the pyramid is 1.191.

how do you find the least common multiple of 16 and 42?

Answers

Hi there!

To find the LCM of 16 and 42, we need to see what numbers can be divided by both 16 and 42 and so on.

16 ÷ 2 = 8
42 ÷ 2 = 21

Now, we multiply the results.

2 × 8 × 21 = 2 × 168 = 336

Fossils are remains of organisms found in sedimentary rock. These remains are found in thousands of rock layers around the world and provide evidence for Earth's long history of changing lifeforms. Rock layers that formed more recently A. contain fossils of animals only. B. contain fossils of plants only. C. contain fossils that resemble existing species less closely than do fossils found in older rock layers. D. contain fossils that resemble existing species more closely than do fossils found in older rock layers.

Answers

Final answer:

Rock layers that formed more recently contain fossils that resemble existing species more closely than do fossils found in older rock layers.

Explanation:

Fossils found in rock layers provide evidence for Earth's long history of changing lifeforms. Rock layers that formed more recently contain fossils that resemble existing species more closely than do fossils found in older rock layers. This is because the more recent layers contain organisms that are more similar to the species that exist today.

Aphrodite traveled 144 leagues in 12 days. Then she doubled her rate. How long would it take her to travel 168 leagues at this new speed?

Answers

D = (168 leagues) / (24 leagues / day) = 7 days 

The first step in solving this problem is to compute for the original rate of Aphrodite.

144 leagues / 12 days = 12 leagues/day (original rate)

It was stated in the problem that she doubled her rate which she means she has a new rate of 24 leagues/day (12 x 2).

168 leagues / 24 leagues/day = 7

Therefore, it would take her 7 days to travel 168 leagues at her new speed.

First, notice that we are given the y-intercept, (0, 5), and the slope, m = 7.

We plug into slope-intercept form [tex]y=mx+b[/tex] to get [tex]y=7x+5[/tex].
Answer:
y = 7x + 5

Explanation:
The equation of line in slop-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept

We are given that the slope = 7. Therefore, the equation becomes:
y = 7x + c

Now, we need to get the value of c. To do so, we will substitute with the given point (0,5) in the equation and solve for c as follows:
y = 7x + c
5 = 7(0) + c
c = 5

Based on the above, the equation of the line is:
y = 7x + 5

i think that your anwser is 125

Answer:

2nd Option is correct.

Step-by-step explanation:

We are given a set of cards containing numbers from 1 to 8 on each cards.

Randomly a card is drawn and noted.

This is repeated 1000 times.

To find: Number of time 4 will be drawn from the pack using theoretical probability.

We know that,

Theoretical Probability: Probability which is based on reasoning  and written as a ratio of the number of favorable outcomes to the total number of outcomes.

Probability of getting 4 from the pack = [tex]\frac{1}{8}[/tex]

Now, Number of the times 4 will be drawn from pack out of 1000 times

= [tex]\frac{1}{4}\times1000[/tex]

= 125
