have a nice day
and u survived ::)))
Answer:
29 inches
Step-by-step explanation:
For the following I just used trial and error and experimented with the possibilities:
29 inches - This is the only one that does not work.
30 inches - We can use 5 of the 6 inch trains, so this is possible.
31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.
32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.
33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

3 1/8 - 7/12
Pls This has to be done!!!
it needs to be in simplest form.
get it right I mark you brainly!
Step-by-step explanation:
To subtract 7/12 from 3 1/8, we need to convert the mixed number 3 1/8 to an improper fraction first:
3 1/8 = (3 × 8 + 1) / 8 = 25 / 8
Now we can subtract 7/12 from 25/8:
25/8 - 7/12 = (25 × 3) / (8 × 3) - (7 × 2) / (12 × 2) = 75/24 - 14/24
= (75 - 14) / 24 = 61/24
So, 3 1/8 - 7/12 = 61/24 in simplest form.
How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

5. Use 3.14 for Pi to estimate the area of a circle. The diameter is given. Round your answer to the nearest hundredth if necessary.
Answer:
Step-by-step explanation:
248.85
Answer:
221.47m^2
Step-by-step explanation:
To estimate the area of a circle, we can use the formula:
Area = π x (radius)^2
Since the diameter of the circle is given as 16.8m, we can first find the radius by dividing the diameter by 2:
radius = diameter / 2 = 16.8m / 2 = 8.4m
Now, using the given value of pi as 3.14, we can estimate the area of the circle as:
Area = π x (radius)^2
= 3.14 x (8.4m)^2
= 3.14 x 70.56m^2
= 221.47m^2 (rounded to the nearest hundredth)
Therefore, the estimated area of the circle is approximately 221.47 square meters.
Profit, P(r), is the difference between revenue, R(r), and cost, C(r), so P(r) = R(r) - C(r) Which expression represents P(r), if R(r) - 2r^4 - 3r^3 + 2r - 1 and C(r) = r^4 - r^2 + 2r + 3?
The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Profit is the difference between revenue and cost. Given that:
R(r) = 2r⁴ - 3r³ + 2r - 1 and C(r) = r⁴ - r² + 2r + 3
P(r) = R(r) - C(r)
P(r) = (2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4
The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

Approximately how many times greater is the mass of a proton than the mass of a electron?
A. 5,500
B. 1,900
C. 19,000
D. 55,000
Answer:
1900
Step-by-step explanation:
hello bro how r u i think answer is 1835 but there is no option
The required mass of the proton is 1900 times the mass of the electron. Option B is correct.
What is proportionality?Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
here,
The mass of an electron is approximately e = 9.1 x 10⁻³¹ kilograms.
The mass of a proton is approximately p = 1.7 x 10⁻²⁷ kilograms.
Now
p/e = 1.7 x 10⁻²⁷/9.1 x 10⁻³¹
p/e ≈ 1900
p = 1900e
Thus, the required mass of the proton is 1900 times the mass of the electron.

So I'm in 6th-grade accelerated class learning 7th-grade math, and our subject is More Two-Step Equations. One of the questions is 8/11(n - 10) = 64. I have to find n, but what does n equal
\(\dfrac{8}{11} (n-10)=64\)
Distribute:
\((\dfrac{8}{11} )(n)+(\dfrac{8}{11} )(-10)=64\)
\(\dfrac{8}{11} n-\dfrac{80}{11} =64\)
Subtract \(\dfrac{80}{11}\) from both sides:
\(\dfrac{8}{11} n-\dfrac{80}{11} +\dfrac{80}{11} =64+\dfrac{80}{11}\)
\(\dfrac{8}{11} n=\dfrac{784}{11}\)
Multiply both sides by \(\dfrac{11}{8}\):
\(\dfrac{11}{8} \times(\dfrac{8}{11} n)=\dfrac{11}{8} \times(\dfrac{784}{11} )\)
\(\fbox{n = 98}\)
Answer:
I found this. I am not sure tho!
To find the value of n in the equation 8/11(n - 10) = 64, you need to first get n by itself on one side of the equation.
To do this, you can start by isolating the n on one side by dividing both sides of the equation by 8/11. This gives you:
n - 10 = 64 * 11/8
Then, you can add 10 to both sides of the equation to get:
n = 64 * 11/8 + 10
You can then simplify this to find the value of n.
64 * 11/8 + 10 = 73
Therefore, n = 73.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;

We have given the points:

Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
