Answer:
Step-by-step explanation:
To represent the solution set of the inequality w divided by 7 > 38 on a number line, we first need to isolate the variable w:
w/7 > 38
w > 7 x 38
w > 266
This means that any value of w greater than 266 satisfies the inequality.
We can represent this on a number line by marking a closed circle at 266 (since the inequality is not inclusive of this value), and drawing an arrow to the right to indicate all values greater than 266:
<--o======(266)---------------->
This represents the solution set of w/7 > 38.

How many degrees is angle 7?
Answer:
42°
Step-by-step explanation:
This is defined as a transversal in geometry, where one line intersects two straight lines.
It is given that one of the angles is 42°. Let the angle that measure 42° be denoted as ∠42.
∠4 ≅ ∠42 based on the alternate interior angles theorem.
∠4 ≅ ∠7 based on the vertical angles theorem.
Therefore, ∠42 ≅ ∠7 based on CPCTC.
Therefore,
m∠7 = 42°.

I have a math test tomorrow about Quadratics and Translations. Can somebody give me an easy-to-understand summary of these key topics?
Transformations with quadratic equations (shift left, right, up, down, reflections, etc.), how to find the axis of symmetry and vertex by the equation, how to find domain and range from a graph, telling if its a quadratic equation by 1st and 2nd difference and anything else related. Also please help me because when creating tables with the equation, the negatives I struggle with for example: y=x^2-4x-6 and substituting -2 it gets super confusing. I WOULD GIVE OUT MORE POINTS but sometimes ppl put bad responses SO PLEASE HELP ME CORRECTLY!! THANK YOU SO MUCH!
Quadratic equations are polynomial equations of degree 2. They can be written in the form ax² + bx + c = 0, where a, b, and c are constants. The graph of a quadratic equation is a parabola.
Transformations involve shifting or reflecting the graph of a quadratic equation. The most common transformations are shifting the graph left or right (by adding or subtracting a constant from x), shifting the graph up or down (by adding or subtracting a constant from y), and reflecting the graph across the x-axis or y-axis.
How to explain the mathematical termsThe axis of symmetry is a vertical line that divides the parabola into two symmetrical halves. The equation of the axis of symmetry for a quadratic equation of the form y = ax² + bx + c is x = -b/2a.
The vertex is the point on the parabola where it reaches its maximum or minimum value. The vertex of a quadratic equation of the form y = ax^2 + bx + c is (-b/2a, c - b²/4a).
The domain of a quadratic equation is the set of all real numbers for which the equation is defined. The range is the set of all possible y-values that the equation can take. You can find the domain and range of a quadratic equation by looking at its graph.
In recognizing quadratic equations, you can tell if an equation is quadratic by looking at the powers of the variables. A quadratic equation will always have a variable raised to the power of 2.
When substituting negative numbers into a quadratic equation, it can be helpful to use parentheses to avoid confusion. For example, to evaluate y = x² - 4x - 6 at x = -2, you would write y = (-2)² - 4(-2) - 6 = 16 + 8 - 6 = 18.

Answer:
25 gallons35 gallonsStep-by-step explanation:
You want the number of gallons of gas used by car 1 at 25 mpg and car 2 at 40 mpg when the total gas used for driving 2025 miles is 60 gallons.
SetupLet x represent the number of gallons used by car 2 at 40 miles per gallon. Then the gas used by car 1 is (60 -x). The number of miles driven is the product of miles per gallon and gallons used.
25(60 -x) +40x = 2025 . . . . total miles driven
SolutionSimplify the equation:
1500 +15x = 2025
15x = 525 . . . . . . . . . . subtract 1500
x = 35 . . . . . . . . . . divide by 15
60-x = 25 . . . . . gallons used by car 1
The first car used 25 gallons; the second car used 35 gallons.

Additional comment
The first car drove 25·25 = 625 miles; the second car drove 40·35 = 1400 miles.

A certain brand of coffee costs $6.99 for 24.2 ounces. What is the unit rate?
Enter your answer, rounded to the nearest cent, in the box.
$____ per oz.
Answer:
B for alyssa : $0.29 per oz, or 29 cents per oz.
Step-by-step explanation:
find common denominator
1x3=3 5x3=15 so 3/15
2x5=10 3x5=15 so 10/15
To find a unit rate, divide the numerator AND denominator by the denominator. The rate is $6.99/24.2 ounces. We will divide $6.99 by 24.2, and 24.2 ounces by 24.2. The answer will be $0.288843/1 ounce. If we round, it will be $0.29/1 ounce.

Calculate the volume of a cone with a height of 6 inches and a diameter of 6 inches.
Leave your answer in terms of PI
Answer: Volume ≈ 56.55
Step-by-step explanation:
56.54867 is the answer, but I rounded it. I hope this helped! :)
Answer:
18π cubic inches
Step-by-step explanation:
First, we need to find the radius of the cone, which is half of the diameter.
radius = diameter/2 = 6/2 = 3 inches
The formula for the volume of a cone is:
V = 1/3 × π × r^2 × h
where r is the radius of the base of the cone, and h is the height of the cone.
Substituting the values we get:
V = 1/3 × π × 3^2 × 6
V = 1/3 × π × 9 × 6
V = π × 18

Find the measure of ∠YOZ by answering the questions.
1. Find the measure of ∠WOV. Which angle relationship did you use? (3 points)
2. Now find the measure of ∠YOZ. Which angle relationship did you use? (3 points)
3. Check your answer by using another strategy to find the measure of ∠YOZ. Describe your strategy, and show that it gives the same measure for ∠YOZ. (4 points)
Answer:1. The measure of ∠WOV is 60°. You would use complementary angles that are adjacent (∠WOV, and ∠XOW)
2. The measure of ∠YOZ is 60°. You would use the vertical angles that are non-adjacent (∠WOV, and ∠YOZ). These two angles are congruent so they would have the same measure. These angles combined also create supplementary angles
3. Another way to find the measure of ∠YOZ would be to make/write an equation and solve for x. For example, (3x+30)°=60°. x would equal 10 because 10x3=30+30=60°
Step-by-step explanation:
1. Since a complementary angle would equal 90°, simply subtract 30° from 90° resulting in 60°.
2. Because vertical angles are congruent and (∠WOV, and ∠YOZ) are a pair of them, they equal the same as each other so they're both 60°.
3. You can make any equation with x included as long as it equals 60° mine was just an example you can make your own like 10x+10=60 or 4x+20=60. Also to create your equation you also need to use the angle fact of the vertical angles

Answer:

Step-by-step explanation:
mangos: m = 108
portugals: p
oranges: o = 3p
108 + p + 3p = 540
108 + 4p = 540
4p = 540-108 = 432
p = 432/4 = 108
o = 3p = 3(108) = 324
324/108 = 3 there are 3 times more oranges than portugals
