Answer:
5 7/15 = D
Step-by-step explanation:
Find a common denominator multiply the many times you did to the denominator to the numerator then subtract.
15 is your common denominator so I would multiply 5 to 2 to get 9 10/15 then I would multiply 3 to 1 to get 4 3/15
Answer:
5 7/15
Step-by-step explanation:
Let's solve your equation step by step.
We will solve it in just 3 simple steps.
Step 1: Converting into Improper Fraction.
Converting into an Improper Fraction is the only way to subtract fractions.
We will turn 9 2/3 into 29/3
First you need to know:
What is a numerator?
What is a denominator?
What is a whole number?
If you know, you can skip this part.
A denominator is the lower number below the line in a fraction. (ex. 2/3 <-- "3" is the denominator)
A numerator is the higher number above the line in a fraction. (ex. 2/3 <---"2" is the numerator)
A whole number is a number that has no fraction or decimal. (ex. "3" or "2" or "7".)
With that said, let's solve.
In 9 2/3, "9" is the whole number. "2" is the numerator, and "3" is the denominator.
We always multiply the whole number by the denominator, then we add the numerator.
So:
(9 x 3) + 2 = 29
Then, we keep the denominator the same. "3".
We then get:
29/3. Which is what we want.
Let's repeat the same steps with 4 1/5.
(4 x 5) + 1 = 21
Keep the denominator : 21/5
Now we are on Step 2.
We currently have 29/3 - 21/5
But we don't have the denominators the same.
We need to find the LCD (Least Common Denominator of 3 and 5.
Since these numbers are less than 10, my trick is to just multiply them together. 3 x 5 = 15, simply put.
Now, let's change all the denominators to 15. Now let's change the numerators.
For the fraction that had 3 as the denominator, let's multiply 5 to it. And for the fraction that had 5 as the denominator, let's multiply 3 to it.
We then get :
145/15 - 63/15
We are now on Step 3.
This step is simple. Just subtract 145 - 63 because the denominators are the same.
145 - 63 = 82
We now have 82/15.
This is the answer, but we always need to simplify it.
How many times can 15 fit into 82? 5. But we have 7 left over.
So we now have :
5 7/15

Answer:
You need to look at the value of x which is already given and insert it into the other values
Step-by-step explanation:
fore example
if x=2
then 5x 5x-1
5(2) 5(2)-1
= 10 10-1
=9
(you put the value of x where x is supposed to be, since x was 2 I replace it with 2 and got the answer).
where we have value of 5x which is 25 we will substitute to get value of x.
5x= 25
x= 25/5
x= 5
Now we have the value of x
Where we have the last value we will substitute it like
5x-1= 34
5x= 34+1
5x= 35
x= 35/5
x= 7
Now we have value of x
10. Write a polynomial in factored form with a single root at 0 and a double
root at 3 that decreases as x approaches infinity.
Answers
Answer:
One possible polynomial is given by: [tex]f(x) = -x(x-3)^2[/tex]
Step-by-step explanation:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
Single root at 0, double root at 3:
This means that:
[tex]f(x) = a(x - 0)(x - 3)(x - 3) = ax(x-3)^2[/tex]
Decreases as x approaches infinity.
This means that the leading coefficient should be negative. I am going to use -1. So
[tex]f(x) = -x(x-3)^2[/tex]

REAL LIFE A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet. Abo
azardous waste can the container hold? Round your answer to the nearest whole number. (1 ft 7.5 gal)
Answers
Answer:
It can hold up to [tex]1.256ft^3[/tex] of waste
Step-by-step explanation:
Given
[tex]D = 1.5ft[/tex] -- Diameter
[tex]h = 1.6ft[/tex] -- height
Required
Determine the amount of waste it can hold
This simply means that we calculate the volume of the cylindrical container.
And this is calculated using:
[tex]Volume = \pi r^2h[/tex]
Where
[tex]\pi = 3.14[/tex]
and
[tex]r = \frac{D}{2}[/tex]
[tex]r = \frac{1.5}{2}[/tex]
[tex]r = 0.75[/tex]
So, we have:
[tex]Volume = 3.14 * 0.5^2 * 1.6[/tex]
[tex]Volume = 1.256ft^3[/tex]
Hence, it can hold up to [tex]1.256ft^3[/tex] of waste
The amount of waste a cylinder can hold nearest to the whole number is 3 cubic feet.
What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet.
The amount of waste a cylinder can hold will be given by the volume of the cylinder.
The volume of the cylinder will be
[tex]\rm Volume = \dfrac{\pi}{4} d^2 h[/tex]
We have
d = 1.5 ft
h = 1.6 ft
Then
[tex]\rm Volume = \dfrac{\pi}{4} * 1.5^2 * 1.6\\\\\rm Volume = \dfrac{\pi}{4} *2.25 * 1.6\\\\\rm Volume = 2.82 \approx 3 \ ft^3[/tex]

I doing vertical angles and I'm way too confused to even understand
Answers
Erotically angles are opposite each other and equal the same degree.
In the image 5x and 120 are vertical angles so 5x needs to equal 120.
X = 120/5
X = 24
Answer:
X=24 degrees.
Step-by-step explanation:
120/5=24. You divide by 5, because the angles will be congruent, and the top angle is 5*_=120. And 5*24=120, so x=24

O removing pennies and dimes from the bag O adding dimes to the bag O adding pennies to the bag o adding pennies and dimes to the bag
Answers
Answer:
Removing pennies and dimes from the bag
Step-by-step explanation:
From the beginning, we have a 1 in 3 chance of drawing a quarter. If we were to add dimes and/or pennies to the bag, this would make us more likely to draw a dime or a penny, and less likely to draw a quarter. Proportionally, we want the most quarters in the bag to get the highest probability of drawing a quarter from the bag.
