Step-by-step explanation:
Find the distance between the points (0,-8) and (8,-3). The answer must be a whole number or a fully simplified radical expression do not round up
Answer:
The distance in radical expression form is d=[tex]\sqrt{89}[/tex]
Step-by-step explanation:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(8-0)^2+(-3-(-8))^2}\\d=\sqrt{(8)^2+(5)^2}\\d=\sqrt{(64)+(25)}\\d=\sqrt{89}\\[/tex]

Point M lies between Points A and B. If AB=12 and AM=7, what is the length of MB?
Answer:
AB= 12
since M is in the middle
AM + MB = 12
or 7 + MB = 12
MB= 12-7=5
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
AM + MB = AB
So, AB - AM = MB
Substituting, 12 - 7 = 5

Step-by-step explanation:
The number of omelets made by 18 eggs will be 6. The correct option is B.
What is the ratio?
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number. The fraction is defined as the division of the whole part into an equal number of parts.
The number of eggs required to make the number of omelets is given in the tables as:-
omelets eggs
? 18
3 9
2 6
1 3
The ratio of omelets and egg is calculated as:-
omelets: egg = 3 : 9
omelets: egg = 1:3
The number of the omelets made by 18 eggs will be calculated as below:-
omelets: egg = 1:3
omelets: 18 = 1:3
omelets = 18 x ( 1 / 3 )
omelets = 6
Therefore, the number of omelets made by 18 eggs will be 6.

find DF if D is between E and F, ED = 6x-4 , DF =3x+5 and EF= 46
Answer:
DF= 20
Step-by-step explanation:
6x-4+3x-5=46
then you solve for x (x=5).
then plug it it : 3(5)+5=20
Value of DF is 20 unit
Given that;ED = 6x - 4
DF = 3x + 5
EF = 46
Find:Value of DF
Computation:We know that;
EF = ED + DF
46 = 6x - 4 + 3x + 5
46 = 9x + 1
9x = 45
x = 5
Value of DF = 3x + 5

Step-by-step explanation:
To find b₂, we need to use our algebraic properties to isolate b₂.
[tex]A=\frac{1}{2}h(b_1+b_2)[/tex] [multiply both sides by 2]
[tex]2A=h(b_1+b_2)[/tex] [divide both sides by h]
[tex]\frac{2A}{h} =b_1+b_2[/tex] [subtract both sides by b₁]

Ben’s age, x, is 3 times his age 12 years ago. Finish the equation, using no spaces
Given :
Ben's age x is 3 times his age 12 years ago.
To Find :
The current age of Ben.
Solution :
It is given that current age of Ben is x.
So, his age 12 years ago is (x - 12).
Expressing given condition mathematically , we get :
[tex]x=3(x-12)\\\\x=3x-36\\\\2x=36\\\\x=18\ years[/tex]
Therefore, current age of Ben is 18 years.
Hence, this is the required solution.
A concert hall has seven sections. Each section has 23 rules. Please roll has 14 seats. If the theater sells out pretty particular performance, how many people attended? If the average ticket sold for $20, how much was collected at the box office? Need to write an equation. Thanks
Answer:
The number of people that attended the performance = 2,254
Amount collected at box office = $45,080
Step-by-step explanation:
For the theater to sell out a performance, it means it was filled to the brim( completely filled)
We have 7 sections, with 23 rows each
The total number of rows will be 23 * 7 = 161 rows
Since each row has 14 seats, the total number of seats will be 161 * 14 = 2,254 seats
Secondly we want to know how much was collected at the box office given the average ticket price
The amount collected at the box office = Number of seats * average ticket price = 2,254 * 20 = $45,080

Answer:
C. 30
Step-by-step explanation:
Distance formula - [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
The scale factor of 7 is basically saying that the coordinates (3,4) are going to be increased 7 times.
3•7 = 21=x --> A prime = (21,28)
4•7 = 28=y
[tex]\sqrt{(21-3)^2+(28-4)^2}[/tex]

Graph the system below and write its solution. Y=1/2x-1
-2x+y=4
You can answer no solution or infinitely many
Answer:
x = -3.3333333
y = -2.666666
Step-by-step explanation:
y = 1/2 x - 1
y = 2x + 4 The second equation has the 2x moved to the right side. The y's must be equal so equation the two equations.
1/2x -1 = 2x + 4 Subtract 1/2x from both sides.
-1 = 2x - 1/2 x + 4 Combine
-1 = 1.5x + 4 Subtract 4 from both sides
-1 - 4 = 1.5x
- 5 = 1.5x Divide both sides by 1.5
-5/1.5 = x
x = - 3.333333
Now put x = - 3.333333 into either one of the two given equations. The first one will require one less step, but it does not matter.
y = 1/2 (- 3.3333333) - 1
y = - 1.6666666 - 1
y = -2.6666666
