What is the answer for "The points (4,r) and (8,-11) lie on a line with slope -3. Find the missing coordinate r."?
Answer:
r = 1Step-by-step explanation:
Use the slope formula:
m = (y₂ - y₁)/(x₂ - x₁)m = -3, x₁ = 4, y₁ = r, x₂ = 8, y₂ = -11Substitute values and solve for r:
-3 = (-11 - r)/(8 - 4)-3 = -(11 + r)/411 + r = 12r = 12 - 11r = 1Answer:
The answer to your question is R=1
Suppose both factors in a multiplication problem are multiples of 10. Why might the number of zeroes in the product be different than the total number of zeroes in the factors?
Answer:
Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
Step-by-step explanation:
Let the first five multiples of ten be
10*1= 10
10*2= 20
10*3=30
10*4=40
10*5= 50
Suppose we chose 20 and 50.
Now multiplying 20 with 50 we get
20*50= 1000
IF we count the total number of zeros in the factors ( 20 and 50) they are 2.
But the number of zeros in the product (1000) are 3.
This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.
And multiplying 10 with 50 we get
10*50= 500
IF we count the total number of zeros in the factors ( 10 and 50) they are 2.
But the number of zeros in the product (500) are also 2.
This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.
Similarly multiplying 20 with 30 we get
20*30= 600
IF we count the total number of zeros in the factors ( 20 and 30) they are 2.
But the number of zeros in the product (600) are also 2.
This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total number of zeros remain the same as in the factors.
So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Shawna needs a new bed pillow. One store
was selling TWO pillows for $19.00. How
much would Shawna pay for ONE pillow?
Answer:
$9.5
Step-by-step explanation:
All you have to do is divide 19 by 2 to get the cost of one pillow. I hope this helps :)
Answer:
$9.50
Step-by-step explanation:
P is Pillows
2P=$19.00
divide by 2 in both sides
P=$9.50
so 1 pillow costs $9.50

Answer:
Assuming you're talking about the angles of a triangle, X would be [tex]34^{.}[/tex]
Step-by-step explanation:
The sum of the angles in a triangle is 180, 180 - 32 - 80 = 68, [tex]\frac{68}{2}[/tex] is 34, so X is equal to [tex]34^{.}[/tex].

Find the 9th term of the geometric sequence 9, -27, 81...
Answer:
a9= 59049
Step-by-step explanation:
Find the r.
R= 81/-27
R= -3
a1= 9
a2= -27
a3= 81
a4= 81*-3= -243
a5= -243*-3= 729
a6= 729*-3= -2187
a7= -2187*-3= 6561
a8= 6561*-3= -19683
a9= -19683*-3= 59049

1 (x + 4) = 20
x = 48
Help please.
Answer:
X actually equals 16 becaausw if yiu add 16+4 you get 20 and then you have to multiply 20 by 1 and you get 20 so x=16
Answer:
x = 16
I dont quite understand the x = 48 situation? But thats wrong if that's your answe
Step-by-step explanation:
So you have to find out what x is
in order to do that you have to work out the equation and whatever you do to one side you must do to the other side
simplify 1(x+4) = 20
x + 4 = 20
in order to get rid of 4 on one side you have to subtract it on both sides
so x = 16

What are the zeros of f(x)=(x+5)(x-9)?
Answer:
x= -5
x= 9
Step-by-step explanation:
Answer:
x = - 5, x = 9
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(x + 5)(x - 9) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 9 = 0 ⇒ x = 9
–27 ≥ t/5 Please help me as soon as possible
Answer:
t ≤ -135
Step-by-step explanation:
multiply each side by 5 which then cancels out the 5 in the fraction then turns -27 into -135. Since we multiplied negatives we flipped the sign.
Which is the solution
Answer:
Step-by-step explanation:
Since this is a test/homework I'll give a hint.
For a linear equation, you have no idea what x and y is, but thats ok! The test itself has already given you 4 options, so you can just input the x/y coordinates, and if they fit, good for you! If they don't, you may need to try again. There are other more complex and faster ways, but they are (a) more complex.
Hope this helps!

Today, Reza ate 20 grapes, which was 400% as many
grapes as he ate yesterday. Explain how to use
equivalent ratios to find the number of grapes Reza ate
yesterday. (help plz)
its not a sin to want to win cant see meflying like a bee i see a dreamer other there by the water but i
LOL
Answer:
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
To do it, let:
x: number of grapes that Reza ate yesterday
(x / 20) = (100/400).
Clearing x we have:
x = (100/400) * (20) = 5
answer
the number of grapes Reza ate yesterday was 5
Step-by-step explanation:
the following cylinder has a volume of 55pi cubic units and a height of 5 units. the cone has the same base area and height, and it has a slant height of 6 units. what is the volume of the cone?
Question:A cone and a cylinder have the same base area. They also have the same curved surface area. If the height of the cylinder is 3m, then the slant height of the cone (in m) is
Answer:
Given the radius of cylinder and cone are the same because there base areas are same.
Curved surface of cylinder = curved surface area of the cone
∴2πrh=πrl
∴l=2h
Given, height of cylinder =3 cm
Therefore, slant height of cone =6 cm
The volume of the cone is 22π.
How to calculate the volume?Volume of a cylinder = πr²h
55π = πr²(5)
55π = 5πr²
r² = 55π/5π
r² = ✓11
r = 3.3
The volume of the cone will be:
= 1/3πr²h
= 1/3 × π × 3.3² × 6
= 1/3 × 11 × 6 × π
= 22π
