Call u the cost per uniform.

Since each of the 15 players gets one uniform and one basketball, we can make the following equation:

15u + 15(9) = 420

Solve this equation to get u=285/15= $19

Answer:

x = 3/2

Step-by-step explanation:

2(x + 5) = 6x + 4

Open bracket first

2 × x + 2×5 = 6x + 4

2x + 10 = 6x + 4

Rewrite equation

6x + 4 = 2x + 10

Subtract 2x from both sides

6x - 2x + 4 = 2x - 2x + 10

4x + 4 = 10

Subtract 4 from both sides

4x + 4 - 4 = 10 - 4

4x = 6

Divide both sides by 4

4x/4 = 6/4

x = 6/4

Divide both denominator and numerator by 2

x = (6/4) ÷ 2

x = 3/2

we are going to create a table in excel and we will assign different values ​​of topping to know when the price is equal in both pizzerias

 

see the attached figure

 

the answer is

5 toppings from palanzio’s pizzeria

6 toppings from guido’s pizza

cost palanzio’s pizzeria----> 6.80+0.90*5-----> $11.30

cost <span>guido’s pizza------> 7.40+0.65*6----------> $11.30</span>

What is the amplitude of sin ?
sp2606 [1]

You haven't provided a graph or equation so I will tell the simplified meaning of amplitude instead.

Amplitude, is basically a distance from midline/baseline to the maximum or minimum point.

For sine function, can be written as:

\displaystyle \large{ y = A \sin(bx  -  c) + d}

  • A = amplitude
  • b = period = 2π/b
  • c = horizontal shift
  • d = vertical shift

I am not able to provide an attachment for an easy view but I will try my best!

We know that amplitude or A is a distance from baseline/midline to the max-min point.

Let's see the example of equation:

\displaystyle \large{y = 2 \sin x}

Refer to the equation above:

  • Amplitude = 2
  • b = 1 and therefore, period = 2π/1 = 2π
  • c = 0
  • d = 0

Thus, the baseline or midline is y = 0 or x-axis.

You can also plot the graph on desmos, y = 2sinx and you will see that the sine graph has max points at 2 and min points at = -2. They are amplitude.

So to conclude or say this:

If Amplitude = A from y = Asin(x), then the range of function will always be -A ≤ y ≤ A and have max points at A; min points at -A.

A side of a led lighting cube is 5 cm long. What is the area of its 6 faces?
ratelena [41]

Answer:

Of all 6 faces it would be 150

Step-by-step explanation:

If one side of the cube is 5cm long, then l × w = area of a face, so if it is a cube then all 4 sides are the same on a face so 5 × 5 = 25, so 25 × 6 faces = 150

Math riddle! Correct answer gets brainliest!<br><br> Answer with what x and y are equal to.
RSB [31]

Answer:

\displaystyle [9, 4\frac{1}{2}]

Step-by-step explanation:

I figure these exercises out by numeric association. I see a 3, so I know right away that there <em>might</em> be a 9 somewhere. So, you start by plugging 3 in for \displaystyle x, THEN plug \displaystyle 1\frac{1}{2} in for \displaystyle y sinse there are <em>twise</em><em> </em>the quantity of \displaystyle y than there are of \displaystyle x. Now, doing so will give you \displaystyle 24 ≠ 18. This tells you to try another pattern, so go with plugging \displaystyle 4\frac{1}{2} in for \displaystyle y and \displaystyle 9 in for \displaystyle x. Doing so gives you what you are looking -- \displaystyle 36 = 36. Therefore, the association wourked perfectly. ☑

I am joyous to assist you at any time.
