Answer:
Step-by-step explanation:
the formula for finding the volume of a cone would be V= 3.14 r sqaured * h/3
so plug that in and it would be 3.14(5.1) sqaured * 13/3
3.14 is the formula of pie which is in the formula for finding the volume of
5.1*5.1= 26.01
3.14* 26.01= 81.67
13/3= 4.34
81.67* 4.34= 354.45
The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.
Calculation of the volume of right circular cone:
Since
We know that
Volume = [tex]\pi r^2 \frac{h}{3}[/tex]
Since the circumference is 5.1 inches
So here the radius be like
Circumference = [tex]2\pi r[/tex]
5.1 = 2(3.14) r
r = 0.8121
Now the volume should be
[tex]= 3.14 \times (0.8121)^2 \frac{13}{3}[/tex]
= 8.97824
Hence, The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.

Determine a relationship between the x- and y-values. Write an equation.
Answer:
X increasing by one and Y decrasees by 2
The correct relation between x and y is [tex]y=x-2[/tex].
Given information:
The table showing the values of x and y is:
x 1 2 3 4
y -1 0 1 2
From the given table, it can be seen that with an increase in the value of x, the value of y also increases.
From the values of y, it can be seen that y increases by 1 unit with a unit increase in x.
The relation between x and y can be written as,
[tex]y=x-2\\y(1)=1-2\\y(1)=-1[/tex]
Therefore, the correct relation or equation between x and y is [tex]y=x-2[/tex].

If the ratio is 3/6 cars (3 = blue, 6 = red) that means that we can simplify it to 1/2. Therefore the amount of red cars is double the amount of blue cars. 30 x 2 = 60, 30 + 60 = 90.

marcus collects donations and sends care packages to troops overseas. He has 36 bars of soap and 24 toothbrushes and wants to arrange the items so the packages are identical. What is the greatest number of packages that Marcus can make using all the soap and toothbrushes?
Answer:
He can make 12!
Step-by-step explanation:
The greatest number of packages that Marcus can make using all the soap and toothbrushes is 12.
Calculation of the greatest number:Since it contains 36 bars of soap and 24 toothbrushes
So here the greatest number should be
= number of bars of soap - toothbrushes
= 36-24

Answer:
B. 3x^2 +11x -20 = 0
Step-by-step explanation:
For solutions p and q, the quadratic will be
(x -p)(x -q) = 0
We notice that the leading coefficients of the offered answer choices are greater than 1, so it will be convenient to use a value that "clears fractions."
(x -4/3)(x -(-5)) = 0
3(x -4/3)(x +5) = 0 . . . . multiply by 3 to clear the fraction
(3x -4)(x +5) = 0 . . . . . . clear the fraction
3x(x +5) -4(x +5) = 0 . . use the distributive property
3x^2 +15x -4x -20 = 0 . . . . use the distributive property again
3x^2 +11x -20 = 0 . . . . collect terms
_____
The constant in the product of factors is the product of roots:
(x -p)(x -q) = x^2 -(p+q)x +pq
Here, that would mean the constant would be (4/3)(-5) = -20/3.
If we compare the above quadratic to the standard form:
ax^2 +bx +c = 0
we find that we can divide the standard form equation by 'a' to get ...
pq = c/a
That is, c/a = -20/3, so we might start looking for an answer choice that has a leading coefficient of a=3 and a constant of c=-20.

Please help me understand how to solve equations like these, I don’t understand them:
Answer:
subtract the unwanted b termdivide by the coefficient of bb = 60Step-by-step explanation:
The numbers 4/5 and 9/10 are fractions. They multiply the variable 'b' in each case.
How to solve an equation like this
An example of an equation like this without fractions is ...
6 + 3b = 8b
You solve this sort of equation by rearranging the equation so the terms having 'b' in them are all on one side of the equal sign. You want all of the terms not containing 'b' to be on the other side of the equal sign.
Here, the terms are mixed on the left, but the right has only a 'b' term. So, if we can remove the 'b' term from the left side, we will have reached the goal
In the example equation, we do that by adding -3b to both sides of the equation.
6 +3b -3b = 8b -3b
Simplifying, we have ...
6 = 5b
Now, we divide by the coefficient of 'b', which is 5. We divide both sides of the equation by that:
6/5 = (5b)/5
6/5 = b . . . . after simplifying
_____
How to solve this equation
The given equation is solved exactly the same way. We add the opposite of the 'b' term that we don't want (which is 4/5b):
6 + 4/5b -4/5b = 9/10b -4/5b
Simplifying, this is ...
6 = (9/10 -4/5)b = (9/10 -8/10)b
6 = 1/10b
We can make the coefficient of 'b' be 1 by multiplying it by 10. We have to do that to both sides of the equation:
(10)(6) = (10)(1/10)b
60 = b . . . . . the solution
_____
Comment on equations in general
The one absolute rule in Algebra is that the equal sign must remain valid. You keep that commandment by observing the properties of equality. Essentially, you can do anything you like to one side of an equation, as long as you do exactly the same thing to the other side.
Here, when we say "subtract 4/5b", the way we keep this commandment is that we do it to both sides of the equation. The same is true for "multiply by 10". This is emphasized by the bold highlighting in the solution shown above.
Comment on arithmetic
In solving this equation, we did the arithmetic using the given fractions. Often, for an equation like this, you will be told the first step is to "eliminate fractions". You can do that here by multiplying the equation by 10:
10(6 +4/5b) = 10(9/10b)
60 +8b = 9b
Now, the unwanted term is 8b, so subtracting that (from both sides) gives ...
60 = b
This is essentially a "2-step" equation, either way you do it.
It is helpful if you are comfortable doing arithmetic with fractions, mixed numbers, decimals, percentages, and numbers in scientific notation, as well as integers.

What are the slope, m, and y-intercept, b, of a line that passes through the points
(3,-1) and (7,-5)?
Answer:
Slope would be m= -1, y-int is 2.
Step-by-step explanation:
To find slope, use (y2-y1/x2-x1) Plugging this in, we get (-5-(-1)/(7-3). This can be simplified to -4/4, which is -1. After we find slope, we plug in one of the points to find be. Using (7,-5), y=-5 and x=7. So, -5=7(-1)+b. -5=-7+b. Add 7 to both sides, b=2. Therefore, the entire equation is y=-x+2.
Answer:
The answer is 1
Step-by-step explanation:
use slope formula!
[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex]
3 is xsub1
-1 is ysub1
7 is xsub2
-5 is ysub2
substitute and solve!
[tex]m= \frac{-5-(-1)}{7-3}\\= \frac{-5+1}{4}\\= \frac{-4}{4}\\= -1[/tex]
slope is 1

Answer:
Answer is after 20 miles
Step-by-step explanation:
10 +2.5x = 3x
10 = 3x-2.5x
10=0.5x
10/.5=x
x=20
At 20 miles they both have a cost of 60
Let's see what to do buddy....
____________________________
Step (1)
Express taxi charges 2.50 $ per mile.
So if each mile equals x the taxi charges 2.50 x.
There's the starting fare too.
So ;
Express taxi charges by the following function :
[tex]f(x) = 2.5x + 10[/tex]
____________________________
Step (2)
Speedy taxi charges 3 $ per mile.
So if each mile equals x the taxi charges 3x .
There's no starting fare.
So ;
Speedy taxi charges by the following function :
[tex]g(x) = 3x[/tex]
____________________________
Step (3)
To find that after how many miles is the cost of both taxi services the same , we must equal their functions.
Then solve for x .
So we have :
[tex]f(x) = g(x)[/tex]
[tex]2.5x + 10 = 3x[/tex]
Subtract the sides of the equation minus 2.5x :
[tex]10 = 0.5x[/tex]
[tex]10 = \frac{1}{2}x \\ [/tex]
Multiply the sides of the equation by 2 :
[tex]x = 20[/tex]
So after 20 miles both taxi services have the same cost.
____________________________
And we're done.
Thanks for watching buddy good luck.

In triangle ABC, it is given that A = 70 degree, B = 52 degree, BO and CO are the bisectors of angle B and angle C
respectively. Find angle OCB andangle BOC.
Answer:
Angle OCB= 35 degrees and Angle BOC= 119
Step-by-step explanation:
ANGLE OCB= 1/2 C (Construction of bisector)
= 1/2 70
= 35
ANGLE OBC= 1/2 B (Construction of bisector)
= 1/2 52
= 26
Therefore, in triangle BOC,
180 degree= ANGLE OBC+ANGLE BOC+ANGLE OCB
180= 35+26+ANGLE BOC
180= 61+ANGLE BOC
ANGLE BOC= 180-61
ANGLE BOC= 119
Answer:
angle ocb=58°
angleboc=96°
Step-by-step explanation:
first get the measure of angle acb which is 58°
this is becoz the total angles in a triangle add up to 180°
angle cbo =26° and angle bco=58°
therefore to get the remaining angle boc ,u add 58 &26 ,then minus from 180
the answer is 96°
