Answer: $216
Step-by-step explanation:
If you divide 90 by 5 then you get 18 so 18 multiplied by 12 is 216.
Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFraction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100
Given:
Two equations are
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
To find:
The reason for same solutions to the proportions.
Solution:
First equation is
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
On cross multiplication, we get
[tex]50\times 20=10\times x[/tex]
[tex]1000=10x[/tex]
Divide both sides by 10.
[tex]\dfrac{1000}{10}=x[/tex]
[tex]100=x[/tex]
The second equation is
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
On cross multiplication, we get
[tex]10\times x=50\times 20[/tex]
[tex]10x=1000[/tex]
Divide both sides by 10.
[tex]x=\dfrac{1000}{10}[/tex]
[tex]x=100[/tex]
Solutions to the proportions are same because both result in the equation 10 x = 1,000, which simplifies to x = 100.
Therefore, the correct option is D.
Answer:
D

Point A ( 5, 3) is reflected across the x-axis what is the coordinate of the image.
Answer:
(5, -3)
Step-by-step explanation:
when you reflect across x axis the y changes symbols.
The Point A(5, 3) is reflected across the x-axis, then the coordinate of the image is (5, -3).
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
Given:
The point A(5, 3) is reflected across the x-axis.
The reflection across the x-axis:
The rule for a reflection over the x-axis is,
(x, y) → (x, −y).
So, the image point,
(5, 3) → (5, −3)
Therefore, the image point is (5, −3).

A game show contestant earns y dollars for completing a puzzle in x minutes. This situation is represented by the equation
y = -250x + 5000. How long did a contestant who earned $500 take to complete the puzzle?
Justify your answer
Answer:
it took them 18 minutes to earn $500
Step-by-step explanation:
Step 1: Flip the equation.
−250x+5000=500
Step 2: Subtract 5000 from both sides.
−250x+5000−5000=500−5000
−250x=−4500
Step 3: Divide both sides by -250.
−250x
−250
=

how do you illustrate quadratic equation in one varible?
Answer:
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.

Thea does not remember in what order she added the ingredients but the last thing she added was 6- 1/4tsp. (6-quarter teaspoons). Select the only option(s) from the checklist below that could have been the last ingredient. * Cinnamon Baking Soda Pure Vanilla Extract Salt Cream of Tartar
Answer:
CinnamonStep-by-step explanation:
From the given ingredient the recipe is meant for cinnamon-sugar cookies
Given the list
(Cinnamon, Baking Soda, Pure Vanilla Extract, Salt ,Cream of Tartar)
With me here is a typical recipe for the baking of cinnamon-sugar cookies
1 cup C&H® Golden Brown Sugar
½ cup C&H® Granulated Sugar
½ cup (1 stick) Unsalted butter, softened
1 teaspoon Pure vanilla extract
2 large eggs
2 ½ cups All-purpose flour
1 teaspoon Cream of tartar
½ teaspoon Baking soda
¼ teaspoon salt
2 tablespoons Granulated Sugar
2 teaspoons ground cinnamon
Now 6- 1/4tsp. corresponds to 6(0.25)=1.5tsp
1.5tsp is a close approximation of 2 teaspoons Ground cinnamon in our typical recipe, hence we could predict that Thea added Cinnamon last
Sonya is a waitress. She earns $200 per week plus a 15% tip on the cost of each meal she serves. What must be the total cost of the meals she serves in order for her to earn at least $425 each week?
help me please
Answer:
Sonya would need to serve 1500 meals
Step-by-step explanation:
425=15%(x)+200 or 425=.15(x)+200
solve for x
425=.15x+200 distribute
subtract 200 from both sides
225=.15x
divide both sides by .15 to isolate x
1500=x or x=1500
