Answer:
3000
Step-by-step explanation:
If you take the amount he already has (1000) and multiply by the reciprocal (4) you'll get $4000, the amount that the car costs. From there subtract the amount he already has (1000) and you get the amount he still needs (3000).
The length of the side of a regular nonagon is 7.86cm. Evaluate the perimeter of the nonagon.
Answer: 70.74
Step-by-step explanation:
A Nonagon has 9 equal sides, and each side of the given is 7.86
So 7.86 multiplied by 9 is 70.74

Answer:
100
Step-by-step explanation:
You move the decimal to the left, 2 times.
You can only move it over like that if you are working with 10, 100, 1,00, ect.
If you were multiplying you would move it to the right.
Answer:
100
Step-by-step explanation:
9. Let p be "an animal is a dog" and let q be "an animal is a golden retriever." Write the conditional statement.
Then decide whether it is true or false.
a. If an animal is a golden retriever, then it is a dog; true
b. If an animal is not a golden retriever, then it is not a dog; false
C. If an animal is a dog, then it is a golden retriever; false
If an animal is not a dog, then it is not a golden retriever; true
Answer:
C. If an animal is a dog, then it is a golden retriever; false
Step-by-step explanation:
Logical reasoning is an important aspect of mathematics.
The conditional statements in the question are represented by the letters p and q. The if-then statement in which the statement p will lead to a conclusion in q is a glaring characteristic of conditional statements. A conditional will be held to be true unless a statement that is true has a false conclusion derived from it.
In the question above, the conditional statement is; If an animal is a dog, then it is a golden retriever. We can clearly see that this conclusion is false.

There are 3 consecutive integers that have a sum of 36. What are the integers?
Answer:
11, 12, 13Step-by-step explanation:
The consecutive integers are increasing by 1
k ← the smallest integer
k+1 ← the middle integer
k+1+1 = k+2 ← the largest integer
k + k+1 + k+2 = 36
3k + 3 = 36
÷3 ÷3
k + 1 = 12
-1 -1
k = 11
k+1 = 11 + 1 = 12
k+2 = 11 + 2 = 13
the sum of two consecutive integers is -35. Name the integers

Step-by-step explanation:put ha times 4 then divide it by ha 23-x²-8x-16=0
what is the solutions by solving by quadratic equations
Answer:
x = - 4
Step-by-step explanation:
Given
- x² - 8x - 16 = 0 ( multiply through by - 1 to clear the leading negative )
x² + 8x + 16 = 0 ← this is a perfect square
(x + 4)² = 0 ( take the square root of both sides )
x + 4 = 0 ( subtract 4 from both sides )
x = - 4

Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of y plus StartFraction one-half EndFraction equals 3 left-parenthesis x minus 2 right-parenthesis.?
y + 2 =y plus 2 equals StartFraction one-third EndFraction left-parenthesis x plus 3 right-parenthesis.(x + 3)
y – 2 = y minus 2 equals StartFraction one-third EndFraction left-parenthesis x minus 3 right-parenthesis.(x – 3)
y + 3 = y plus 3 equals StartFraction one-third EndFraction left-parenthesis x plus 2 right-parenthesis.(x + 2)

What is the slope of this line?
A. 3
B. -1/3
C. -3
D. -2
E. 4
Answer:
-3
Step-by-step explanation:
Pick two points on the graph, lets go with (0, 4) and (1, 1)
y = mx + b
m is the slope and to figure it out use below formula
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - 4) / (1 - 0)
= -3 / 1
= -3
Answer:
C. -3
Explanation:
Given problem;
To solve for the slope of the line;
The slope of a line is the vertical distance to the horizontal displacement on a line.
Slope = [tex]\frac{Vertical distance}{horizontal displacement}[/tex]
For lines such as this, we use the formula below;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
To find the slope reference the image attached;
point 1 (0,4) x₁ = 0 y₁ = 4
point 2 (2,-2) x₂ = 2 y₂ = -2
Now input the parameters and solve;
Slope = [tex]\frac{-2 - 4}{2 - (0)}[/tex] = [tex]\frac{-6}{2}[/tex]
Slope = -3
The slope of the line is -3
Determine whether side-angle-angle (SAA) is a valid means for establishing triangle congruence. In this case, you know the measure of a side, an adjacent angle, and the angle opposite to the side. If it is a valid criterion, explain why. If it is not valid, use GeoGebra to create a counterexample demonstrating that it doesn't work and give an explanation. If you construct a counterexample, take a screenshot of your work, save it, and insert the image in the space below.

A factory made 357,945 baseball bats over the last 2 years. During that time, the factory made 490,867 little league baseballs and 389,839 major league baseballs. How many more baseballs than bats were manufactured during the 2 years? Liliana's answer to this question is below. Her teacher says her answer is not reasonable. Look over her work before answering (a) and (b).
Answer:
522,761 baseballs
Step-by-step explanation:
Number of baseball bats produced over the last 2 years = 357, 945
Number of little league baseballs produced over the last 2 years = 490,867
Number of major league baseballs produced over the last 2 years = 389,839
Total number of baseballs produced over the period = 490,867 + 389,839
= 880,706
Number of baseballs manufactured more than bats = 880,706 - 357945
= 522,761
There are 522,761 baseballs produced more than bats during the 2 years.
29. Find the measure of each angle.
E
с
(5x + 2)
3x
B
Answer:
The measure of each angle is :
3x° = 33°
(5x+2)° =57°
Step-by-step explanation:
From the diagram, angle <ABC is a right-angle triangle with a measure of 90°
This means the sum of the two angles <ABE + <CBE =90°
Given from the question :
<ABE = 3x°
<CBE = (5x+2)°
For an equation for sum of the two angles as;
<ABE + <CBE =90°
3x° + (5x+2)° = 90° ------collect like terms after opening the brackets
3x° +5x° + 2° =90°
8x°=90°-2°
8x°=88°
x°=88°/8° = 11°
Measure of the angles will be:
<ABE = 3x° = 3*11° = 33°
<CBE = (5x+2)° = (5*11° +2° ) =55°+2°= 57°
Answers are :
3x° = 33°
(5x+2)° =57°
True or false. The solution to an equation in two variables such as y = 3x - 9 is the value of x that makes the equation true.

What is the simplest form of 4a + 8b/12
Step by step pls
Answer:
4a + 2b/3
Step-by-step explanation:
focus on 8b/12 first:
factor 8b/12 by 4 ---> 8b/12 = 4(2)b/4(3) ----> cancel 4 in the denominator and the nominator ---> 8b/12 = 4(2)b/4(3) = 2b/3
then, go back to 4a:
4a is in its simplest form, it can't be factor
therefore, plus 4a and 2b/3 = 4a + 2b/3
