There are 60 cars in a used car lot.
Ford made 3/10 of the cars.
General Motors made 1/6 of the cars.
Honda made the remaining cars.
In this car lot, Honda made —
Answer:
Honda made 32 cars
Step-by-step explanation:
Total no. of cars = 60
car made by ford = 3/10 of total no of cars
car made by ford = 3/10 of 60 = 3/10* 60 = 18
car made by General Motors = 1/6of total no of cars
car made by General Motors = 1/6 of 60 = 1/6* 60 = 10
No of cars made by Honda = Total no. of cars - car made by ford - car made by General Motors
No of cars made by Honda = 60 - 18 - 10 = 32
In this lot, Honda made 32 cars.
2(x – 2) + 6 = 0
can anyone tell me the answer with steps please
Answer:
x = -1
Step-by-step explanation:
2(x – 2) + 6 = 0
~Distribute left side
2x - 4 + 6 = 0
~Combine like terms
2x + 2 = 0
~Subtract 2 to both sides
2x = -2
~Divide 2 to both sides
x = -1

The linear function m = 3a represents the amount m in dollars) of money a customer pays after buying a phone apps. Each customer can buy a maximum of three apps.
1. Identify the independent and dependent variables.
2. Is the domain discrete or continuous? Explain.
Answer:
1. The independent variable is a and the dependent variable is m
2. The domain is discrete
Step-by-step explanation:
let us explain the difference between discrete or continuous domains
Discrete domain: It is a set of input values that consists of only certain numbers in an interval.
Continuous domain: It is a set of input values that consists of all numbers in an interval.
In the question
m = 3a, where
m is the amount of money m in dollars
Each customer can buy a maximum of three apps
1.
∵ m is depended on the value of 3a
∴ m is the dependent variable ⇒ (output)
∴ a is the independent variable ⇒ (input)
∴ The independent variable is a and the dependent variable is m
2.
∵ The domain the input values
∴ Each customer can buy a maximum of three apps
→ That means it is a certain numbers
∴ The domain is discrete
find the area of the triangle
Answer:
The answer is
[tex] \huge \boxed{54 \: \: {units}^{2} }[/tex]
Step-by-step explanation:
Area of a triangle is given by
[tex]A = \frac{1}{2} \times base \times height \\ [/tex]
From the question
base = 18
height = 6
So we have
[tex]A = \frac{1}{2} \times 18 \times 6 \\ = 9 \times 6 \\ = 54 \: \: \: \: \: [/tex]
We have the final answer as
54 units²Hope this helps you
Answer:
The answer is 54 units squared
Step-by-step explanation:
This is because this triangle is made up of two triangles. The smaller one is an isosceles triangle, meaning all sides are the same length. Sense all sides are the same length each side = 6 units squared. You subtract 6 from 18 to get the length of the other triangles side.
From there you multiply each side as if it were a square, then divide both answers by two (because two triangles make up a square). Add them up and then Ta-daa! 54!
a mountain gorilla weighs 135 pounds and is gaining 1/2 pounds each week an eastern gorilla weigh 145 pounds and is loosing 1/4 pounds each week which of the following equation could be use to determine x, the number of weeks that it will take until the two gorilla weigh the same amount?
A. 135 + 1/2x = 143 + 1/4x
B. 135 + 1/2x = 143 - 1/4x
C. 135x +1/2 = 143x + 1/4
D. 135 + 1/2x = 143 + 1/4x
Answer:
I think its b because is says loosing 1/4 lbs each week. That would be subtraction. The others are adding.
The equation that represents two Gorillas weighing the same is,
B. 135 + (1/2)x = 143 - (1/4)x.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, A mountain gorilla weighs 135 pounds and is gaining 1/2 pound each week and an eastern gorilla weighs 145 pounds and is losing 1/4 pound each week.
The weights of the two Gorillas will be the same when we'll equate their individual equations which is,
135 + (1/2)x = 143 - (1/4)x.
Solving for 'x' would give us the number of weeks required for two Gorillas
to weigh the same.

Find the measure of each angle in the diagram.
Answer:
10y° = 130°
(4x - 22)° = 50°
(7x + 4)° = 130°
(3y + 11)° = 50°
Step-by-step explanation:
From the picture attached,
Two lines are intersecting each other at a pint making two pairs of vertical angles.
By definition, pair of vertical angles are equal in measure.
10y° = (7x + 4)° [Vertical angles]
-7x + 10y = 4 -----(1)
(3y + 11)° = (4x - 22)° [Vertical angles]
-4x + 3y = -33 ------(2)
[Equation (1) × 3] - [Equation (2) × 10]
(-21x + 30y) - (-40x + 30y) = 12 + 330
-21x + 40x = 342
19x = 342
x = [tex]\frac{342}{19}=18[/tex]
From equation (1),
-7(18) + 10y = 4
-126 + 10y = 4
10y = 130
y = 13
Therefore, 10y° = 130°
(4x - 22)° = 50°
(7x + 4)° = 130°
(3y + 11)° = 50°

Solve 5(x+3)=2x+3 what does x equal
Answer:
x= -4
Step-by-step explanation:
1. Expand the brackets (multiply everything inside by the number outside):
5x + 15= 2x + 3
2. Move all of the x terms to one side and all of the number terms to the other:
Subtract 2x from both sides
5x-2x + 15= 2x-2x + 3
3x + 15= 3
Subtract 15 from both sides
3x + 15- 15= 3 - 15
3x= -12
3. Solve for x:
x= -12/3
x= -4

Step-by-step explanation:
The ages of three sisters are consecutive integers with the sum of 180. How old are each of the brothers?
Write and solve and equation the above situation describes.
Answer:
Step-by-step explanation:
The age of three sisters are consecutive integers meaning they are only one year apart.
E.g. sister 1 = x yrs old
Sister 2 = (x + 1) yrs old
Sister 3 = (x + 2) yrs old
They have a sum of 180 meaning if you add all 3 of their ages, you get a total of 180.
Sister 1 + sister 2 + sister 3 = 180
x + (x + 1) + (x + 2) = 180
So gather the like terms and you get:
3x + 3 = 180
Subtract 3 from both sides
3x = 180-3 = 177
Solve for x by dividing both sides by 3.
x = 177/3 = 59
So now we know what x is so you just plug it back into the equations at the beginning for the ages of each of the sisters.
Sister 1 = x = 59
Sister 2 = x + 1 = 59 + 1 = 60
Sister 3 = x + 2 = 59 + 2 = 61

Below are the test scores for Ms. Brown's 1st and 2nd period math classes. Analyze the data and choose EACH correct statement:
1st period (Class A): 10, 15, 20, 25, 30, 35, 40
2nd period (Class B): 7, 12, 17, 25, 33, 38, 43
The standard deviation for Class A is 10
The standard deviation for Class B is 12.615
The mean (average) score for each class is the SAME.
The mean (average) score for each class is DIFFERENT.
The variance for Class A is 125.
The variance for Class B is 159.14.
choose each correct statement:
Class A has a greater spread.
Class B has a greater spread.
Based on the data, a score of 8 is more likely in Class B than Class A.
If graphed, Class B would look more like the red graph below and Class A would look more like the blue one.
Answer:
The correct options are;
1) The mean (average) score for each class is the SAME
2) The variance of Class B is 159.14
3) Class B has a greater spread
4) Based on the data A score of 8 is more likely in class B than in class A
Step-by-step explanation:
The given data are;
For the 1st period (Class A), we have
The mean, μ = (10 + 15 + 20 + 25 + 30 + 35 + 40)/7 = 175/7 = 25
The standard deviation σ, is given as follows;
[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}}[/tex]
Where;
N = The number population size = 7
[tex]x_i[/tex] = The individual data values
Solving using Microsoft Excel formula STDEV.P gives, σ = 10
[tex]\sigma _A[/tex] ≈ 10
The variance = σ² = 10² = 100
For the 2nd period (Class B), we have
The mean, μ = (7 + 12 + 17 + 25 + 33 + 38 + 43)/7 = 175/7 = 25
The standard deviation σ, is given as follows;
[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}}[/tex]
Where;
N = The number population size = 7
[tex]x_i[/tex] = The individual data values
Solving using Microsoft Excel formula STDEV.P gives, [tex]\sigma _B[/tex] ≈ 12.615
[tex]\sigma _B[/tex] ≈ 12.615 > [tex]\sigma _A[/tex] ≈ 10, class B has greater spread
The variance = σ² = 12.615² ≈ 159.14
A score of 8 is more likely in class B than in class A due to the availability of data before and after the a score of 8

Answer:
19
Step-by-step explanation:
Simplify the following:
35/5 + 3 (30 - 3^3 + 1)
The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:
7 + 3 (30 - 3^3 + 1)
3^3 = 3×3^2:
7 + 3 (30 - 3×3^2 + 1)
3^2 = 9:
7 + 3 (30 - 3×9 + 1)
