Answer:
there were 8 dog ears in all.
Step-by-step explanation:
Since the statement says that they saw two teachers each walking with two dogs, you have to multiply the number of teachers for the number of dogs each one had to find the total number of dogs they had:
2*2=4
Now, as the statement indicates that each dog had two ears you have to multiply the number of dogs for the number of ears each one has:
4*2=8
According to this, the answer is that there were 8 dog ears in all.
two numbers are in the ratio 2:5. If 6 is subtracted from their sum, the result is 50. what is the larger number
Answer:
(2x+5x)-6=50
7x =56
x=8
5>2, so 5 is the bigger one
5*8=40
the answer is 40

Which equations have 8 as a solution?
15-n=7 n + 3 = 12 4n = 32
64 : n = 8
Select all the equations that have 8 as a solution.
A. 15-n=7
B. n + 3 = 12
C. 4n = 32
D. 64:n = 8
Answer:
The equations 15 - n = 7, 4n = 32, and 64 : n = 8 have 8 as a solution.
Step-by-step explanation:
Each equation will have work shown below :
15 - n = 7
For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to subtract and the inverse operation of that is addition. Since the original operation is subtraction, we need to add it by a negative sign to each side. In order to isolate the variables, we have to add -7 to both sides.
15 - n = 7
+ -7 + -7
8 = n
The right side has a sum of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.
4n = 32
For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to multiply and the inverse operation of that is division. In order to isolate the variables, we have to divide 8 to both sides.
4n = 32
/4 /4
n = 8
The left side has a quotient of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.
This is a ratio which is basically just the operation of division. For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to divide and the inverse operation of that is multiplication. Since the original operation is division, we need to multiply it by the reciprocal to each side. In order to isolate the variables, we have to multiply 1/8 to both sides.
64 : n = 8
* 1/8 * 1/8
8 = n
The right side has a product of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.

Note: Consider we need to find the factor form of the given expression by taking out the GCF.
Given:
The expression is:
[tex]-42k^3+24k^4+12k^5[/tex]
To find:
The factor form of the given expression.
Solution:
We have,
[tex]-42k^3+24k^4+12k^5[/tex]
It can be written as:
[tex]=6k^3(-7)+6k^3(4k)+6k^3(2k^2)[/tex]
Taking out the greatest common factor (GCF), we get
[tex]=6k^3(-7+4k+2k^2)[/tex]
Therefore, the factor form of the given expression is [tex]6k^3(-7+4k+2k^2)[/tex].

Answer:
150.8[tex]yd^3[/tex]
Step-by-step explanation:
I helped lol.
Have a nice day! :-)
Answer:
150.7
Step-by-step explanation:
Formula for volume of a cone = [tex]\pi r^2\frac{h}{3}[/tex]
where r = radius and h = height
We are given the diameter ( 8yds ) and the height ( 9yds )
In order to find the volume we need to find the radius
We can do this my dividing the diameter by 2 ( this is because the radius is equal to half the length of the diameter)
8/2 =4
So the radius is equal to 4yds
Now we plug in the values into the formula
( remember it says use 3.14 for π )
[tex]V=(3.14)4^2\frac{9}{3} \\4^2=16\\16*3.14=50.24\\\frac{9}{3} =3\\3*50.24=150.72[/tex]
Finally we round to the nearest tenth and get that the answer is 150.7yd²
