How many 1/8-inch pieces of ribbon can be cut from a piece of ribbon that is 3/4 inch long? *
Answer:
the answer is 6
Step-by-step explanation:
Find what's 1/8 divided by 3/4 in fraction form?
step 1 Address formula, input parameters & values.
Input parameters & values:
1/8 and 3/4
Step 2: change the problem
Remember, always do KCF(Keep,Change,Flip)
First i keep 1/8
1/8 ÷ 3/4
Then I change the sign to multiplication because you need to need to find the answer and simplified it
1/8 x 3/4
Make sure u always flip the other fraction because you are multiplying
1/8 x 4/3
then you do the rest
Step 3:solve
1/8 x 4/3=4/24
Step 4: simplified
24/4=6
Now your answer is 6
Hope it helps :)

Find the slope of the following graph and Identify the type of
Slope:
Answer:
undefined
Step-by-step explanation:
Horizontal lines have no slope. The line on the graph is vertical, so we can't really tell what slope it is. But there isn't any run and only rise, therefore the slope is "undefined."

Answer:
3 was subtractedboth sides were divided by 3both sides were multiplied by -3both sides were divided by -3Step-by-step explanation:
It looks like you have four different equations here.
As a rule, each step in the solution involves one of the properties of equality: addition, subtraction, multiplication, or division. These properties let you do the same thing (one of these operations) to both sides of the equation.
__
1. 10 − 6 x = 4 + 5x
7 -6x = 1 +5x . . . . 3 was subtracted from both sides*
__
2. 3 ( 4 x − 3 ) = − 15
4x -3 = -5 . . . . . both sides were divided by 3
__
3. 5x/-3=12/1
5x=-36 . . . . both sides were multiplied by -3
__
4. −3 ( 4 x − 3 ) = − 15
4x -3 = 5 . . . . both sides were divided by -3
_____
* For this equation it would have been more useful to subtract 4 to get ...

What’s the combined average of Altuve’s weighted average below:
Friday 3 for 5, Saturday 2 for 4, and Sunday 1 for 3
Answer:
The combined average of Altuve's weighted averages is 1 for 2 or 1/2
Step-by-step explanation:
Combined Average
On Friday, Altuve had 3 out of 5 successes
On Saturday, Altuve had 2 out of 4 successes
On Friday, Altuve had 1 out of 3 successes
The total successes are 3+2+1=6
The total tries are 5+4+3=12
The combined average is:
[tex]\displaystyle \bar x=\frac{6}{12}[/tex]
Simplifying:
[tex]\displaystyle \bar x=\frac{1}{2}[/tex]
The combined average of Altuve's weighted averages is 1 for 2 or 1/2
Elena's father put $460 into a savings account for her. The account pays 2.5% simple interest each year. If he neither adds nor withdraws
money from the account, how much interest will the account earn after 4 years? Round to the nearest cent.
Answer:
$46
Step-by-step explanation:
Give that Elena's father put $460 into a savings account.
So, the principal amount, P= $ 460
Yearly simple interest , R= 2.5% = 0.025
Time, t = 4 years.
The interest, I, for the principal amount, P, at the rate of R yearly, after t years,
[tex]I= P\times R \times t[/tex]
By using the given values, we have
[tex]I=460\times 0.025 \times 4 = 46[/tex]
Hence, the account will earn $46.

Add 3 level scoops of mini chocolate chips and 1 level scoop of raisins to Container 1. If each scoop has the same number of items, what percent of the items in Container 1 are mini chocolate chips? (This value is known as the percent concentration of chips.) Explain how you decided. Label the container appropriately Answer: 50% because when there is only 2 variables and they are each 1 cup there is an even amount of stuff and when you ask for only one percentage that would be 50% because everything is even. Even if you asked for the percentage for the cup of raisins it would also be 50% Add 2 scoops of mini chocolate chips and 3 scoops of raisins to Container 2. What is the percent concentration of mini chocolate chips? Explain how you decided. Label the container appropriately. Stir the chips and raisins in each container to ensure that the chips and raisins are evenly mixed.
Answer:
Container 1
The percentage of mini chocolate chip is 3/4 * 100= 75 % to raisins.
Container 2
The percentage of mini chocolate chip is 2/5 * 100= 40 % to raisins.
Step-by-step explanation:
Container 1
Mini Chocolate Chips: Raisins
3 scoops: 1 scoop
The percentage of mini chocolate chip is 3/4 * 100= 75 % to raisins.
Container 2
Mini Chocolate Chips: Raisins
2 scoops: 3 scoop
The percentage of mini chocolate chip is 2/5 * 100= 40 % to raisins.
This is simplified with the help of the ratios . We find out the ratio of the mini chocolate to the total of both the ratios and mulitply it with 100 to get the percentage concentration.
estimate 1scoop chips and 2scoops rice percentage
Solve: 2.3 = v + 0.47 v = _____
Answer:
2.3=v+0.47v=
We move all terms to the left:
2.3-(v+0.47v)=0
We add all the numbers together, and all the variables
-(+1.47v)+2.3=0
We get rid of parentheses
-1.47v+2.3=0
We move all terms containing v to the left, all other terms to the right
-1.47v=-2.3
v=-2.3/-1.47
v=1+0.83/1.47
Answer:
[tex]v = 1.564[/tex]
Step-by-step explanation:
[tex]1v + 0.47v = 2.3[/tex]
[tex] = > 1.47v = 2.3[/tex]
[tex] = > v = \frac{2.3}{1.47} = 1.564[/tex]
An airline has two flights each day from City A to City B. A random sample of 10 morning flights left the gate an average of 15 minutes late with a standard deviation of 5 minutes. A random sample of 10 evening flights left the gate an average of 20 minutes late with a standard deviation of 3 minutes. Suppose both the morning and evening flights are 30 minutes late. To determine which flight is more late than usual, first find the z-scores. Round to one decimal place if necessary.
Answer:
Step-by-step explanation:
Let X denote the random variable that obeys the normal distribution.
Given that:
For morning flights
Mean [tex]\mu_1[/tex] = 15
standard deviation [tex]\sigma_1[/tex] = 5
Sample size [tex]n_1[/tex] = 10
[tex]X_1 \sim Normal ( \mu_1, \sigma _1)[/tex]
The Z - score is calculated as:
[tex]Z = \dfrac{x_1 - \mu_1}{\sigma_1}[/tex]
[tex]Z = \dfrac{30 -15}{5}[/tex]
[tex]Z = \dfrac{15}{5}[/tex]
Z = 3
For evening flights
Mean [tex]\mu_2[/tex] = 20
standard deviation [tex]\sigma_2[/tex] = 3
Sample size [tex]n_2[/tex] = 10
[tex]X_2 \sim Normal ( \mu_2, \sigma _2)[/tex]
[tex]Z = \dfrac{x_2 - \mu_2}{\sigma_2}[/tex]
[tex]Z = \dfrac{30 -20}{3}[/tex]
[tex]Z = \dfrac{10}{3}[/tex]
Z = 3.33
Hence, from the above z-scores, we will realize that the evening flight is more late than usual.
The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:
Graph titled Distance Vs Time is shown with Time in minutes along the x axis and Distance from Nest in miles along the y axis. The scale on the x axis shows the numbers 0 to 25 at increments of 5, and the scale on the y axis shows the numbers 1 to 8 at increments of 1. A straight line joins the ordered pairs 0, 3 and 5, 4 and 10, 5 and 15, 6 and 20, 7.
Based on the graph, what is the initial value of the graph and what does it represent? (1 point)
a
3 miles per minute; it represents the speed of the bird
b
0.2 mile per minute; it represents the speed of the bird
c
0.2 mile; it represents the original distance of the bird from its nest
d
3 miles; it represents the original distance of the bird from its nest
Answer:
(d).
Step-by-step explanation:
The y-intercept (0, 3) is initial value of graph ⇒ (d). 3 miles; it represents the original distance of the bird from its nest
Answer:
0.2 mile; it represents the original distance of the bird from its nest

Answer:
[tex]x=\dfrac{-(-1)\pm \sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}[/tex]
Step-by-step explanation:
The quadratic equation is as follows :
[tex]7x^2=9+x[/tex] ...(1)
The solution of a quadratic equation [tex]ax^2+bx+c=0[/tex] is given by :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Equation (1) can also be written as follows :
[tex]7x^2-9-x=0\\\\7x^2-x-9=0[/tex]
Here, a = 7, b = -1 and c = -9
[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, x=\dfrac{-b-\sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-(-1)+\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}, \dfrac{-(-1)-\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}\\\\x=1.20\ s, -1.06\ s[/tex]
Neglecting negative value.
So, it will hit the ground in 1.2 s.

Answer:
x = 35 y = 82
Step-by-step explanation:
all triangles add up to 180
the tick mark shows that 2x = y - 12
2x + 2x + 40 = 180
4x + 40 = 180
4x = 140
x = 35
y - 12 + y - 12 + 40 = 180
2y - 24 + 40 = 180
2y + 16 = 180
2y = 164
y = 82
Check:
40 + 2(35) + (82 - 12) = 180
