Answer:

2 gallons

Step-by-step explanation:

So say we make everything into cups. We know there is 4 cups in a quart and 2 cups in a pint. So if we do the math you are really adding

4 cups + 4 cups + 8 cups + 16 cups

So that  would be 32 cups.

We also know there is 16 cups in a gallon. Since we know that then we can do

32 cups ÷ 16 cups

That would be 2 gallons!

Hope this helps!

Final answer:

Jeff makes 2 gallons of fruit punch by converting all the liquid measurements to pints and then summing them up to convert to gallons.

Explanation:

To determine how many gallons of fruit punch Jeff makes, we need to convert all the measurements to the same unit and then add them together. Here are the conversions we'll use:

1 quart = 2 pints

1 pint = 2 cups

1 gallon = 4 quarts

1 gallon = 8 pints

1 gallon = 16 cups

Now let's convert everything to pints since most of the units provided are in pints:

Orange juice: 1 quart = 2 pints

Pineapple juice: 2 pints

Tropical punch: 8 cups = 4 pints

Ginger ale: 8 pints

Add all the pints together:

2 pints (orange juice) + 2 pints (pineapple juice) + 4 pints (tropical punch) + 8 pints (ginger ale) = 16 pints total

Now convert pints to gallons:

16 pints ÷ 8 pints/gallon = 2 gallons

So, Jeff makes 2 gallons of fruit punch.

Answer:

-5,120

Step-by-step explanation:

The pattern is increasing by x*2

I would say -100

You would find this out by identifying your 'a' which is the first number of the sequence, in this case it is -5

Then you would find the common ratio. You do that by dividing any two of the numbers after your 'a' For this one I chose to divide -20 by -10 and that gets you 2.

You would multiply those together, getting you -10.

So, from here you would put the term you are trying to find (in this case it is the 11th term) and subtract it by one

11-1=10

Lastly, you would multiply your -10 by 10 and get yourself a -100

Formula: nth term =  a1^n-1

Hope this helps :) Sorry if it is kinda confusing...

x = -4

Let the number = x (set up an equation)

2x = -3x - 20

add 3x to both sides

5x = -20

divide by 5 on both sides

x = -4

The question involves creating and solving an algebraic equation. By interpreting the word problem, we create the equation 2x = -3x - 20. Solving this equation, we find that the number in question is -4.

The subject matter here is algebra, which falls under Mathematics. From the question, we can create an algebraic equation to find the number. Since the product of the number and 2 is 20 less than the product of the number and -3, we can write this as 2x = -3x - 20, with 'x' representing the unknown number. Solving this equation for x, we add 3x to both sides, turning the equation into 5x = -20. Dividing both sides by 5, we find that x = -4. So, the number is -4.

1.7 ft2 If the surface area is 6.8 ft2 then 1.7ft2 x 4 =6.8FT2

The area of each Triangle is 1.7 ft².

A 3-dimensional solid prism's surface area is determined by the form of its base. A prism's surface area is the total area occupied by the prism's faces. A prism is a flat-faced polyhedron. It lacks curves.

The surface area of a prism is the amount of total space occupied by the prism's flat faces. Determining a prism's surface area entails calculating the total space occupied by all the faces of that particular type of prism or the sum of the areas of all faces (or surfaces) in a 3D plane.

We have

Surface Area = 6.8 ft²

As, the Figure have 4 Triangle.

Then, the Area of each Triangle

= 6.8 / 4

= 1.7 ft²

Answer:

x = 1

Step-by-step explanation:

Given in the question the equation

y = -x² + 2x - 1

To find the x-intercept, substitute in 0 for y

0 = -x² + 2x - 1

To find value of x use quadratic equation

x = -b ± √b²-4ac / 2a

  here a = -1

           b = 2

           c = -1

x1 = -2 + √2²-4(-1)(-1) / 2(-1)

   = -2 + 0 / -2

   = -2 / -2

   = 1

x2 = -2 - √2²-4(-1)(-1) / 2(-1)

   = -2 - 0 / -2

   = -2 / -2

   = 1

In order to determine the number of different outcomes for the two pass attempts in overtime, we need to consider the possibilities for each pass attempt. Let's break it down step by step:

For the first pass attempt, there are three possible outcomes: completion, incompletion, or turnover. Let's say the first pass attempt resulted in a completion.

For the second pass attempt, again there are three possible outcomes: completion, incompletion, or turnover. Since we are considering all possible outcomes, we will consider each possibility for the second pass attempt separately.

If the first pass attempt was a completion and the second pass attempt is also a completion, then we have one possible outcome.

If the first pass attempt was a completion and the second pass attempt is an incompletion, then we have one possible outcome.

If the first pass attempt was a completion and the second pass attempt is a turnover, then we have one possible outcome.

Now, let's consider the other possibilities for the first pass attempt.

If the first pass attempt was an incompletion and the second pass attempt is a completion, then we have one possible outcome.

If the first pass attempt was an incompletion and the second pass attempt is also an incompletion, then we have one possible outcome.

If the first pass attempt was an incompletion and the second pass attempt is a turnover, then we have one possible outcome.

Lastly, let's consider the remaining possibility for the first pass attempt.

If the first pass attempt was a turnover, then it does not matter what the outcome of the second pass attempt is, as the possession has already changed. Therefore, we have one possible outcome in this case.

Adding up all the possible outcomes, we have a total of 7 different outcomes for the two pass attempts in overtime.

Therefore, the correct answer is C) 7.

Answer: 7.97 meters

Step-by-step explanation:

You must use the formula for calculate the area of a circle, which is:

[tex]A=r^2\pi[/tex]

Where r is the radius of the circle.

The diameter of the circle is:

[tex]D=2r[/tex]  

Solve for r from  [tex]D=2r[/tex]  

[tex]r=\frac{D}{2}[/tex]

Substitute the area and [tex]r=\frac{D}{2}[/tex] into the first equation and solve for the diameter. Then you obtain:

[tex]50m^2=(\frac{D}{2})^2\pi\\\\50m^2=\frac{D^2}{4}\pi\\\\D=\sqrt{\frac{4*50m^2}{\pi}}\\D=7.97m[/tex]

Answer:

The  diameter of a circle that has 50 square meters = 7.98 m

Step-by-step explanation:

Formula

Area of circle = πr²

Where 'r' is the radius of circle

Diameter of circle d = 2r

It is given that area of circle = 50 square meters

To find the radius of circle

we have,

Area of circle = πr² = 50

r² = 50/π = 50/3.14 = 15.924

r = √15.924 = 3.99

To find the diameter of circle

Diameter = 2r = 2 * 3.39 = 7.98 m

The solution to the given equation is x = -7/9, after simplifying and solving for x.

To simplify the equation -4(x + 4x) = 2(2 - x) + 10, start by combining like terms within the parentheses: -4(5x) = 2(2 - x) + 10. This leads to -20x = 4 - 2x + 10. Further simplifying, you get -20x = 14 - 2x. Now, add 2x to both sides to eliminate the variable on the right, resulting in -18x = 14. To isolate x, divide both sides by -18, yielding x = -14/18, which can be further reduced to x = -7/9. In summary, the equation simplifies to x = -7/9 after a series of steps.

If the circumference is 34 Times PI that means that 34 is the diameter.

So that means that you can just divide the diameter by 2 to get the radius (Because the radius is half of the diameter.)

So the answer is the diameter is 34 and the radius is 17

Final answer:

The diameter of the circle with a circumference of 34π is 34 units, and the radius is half the diameter, which is 17 units.

Explanation:

The circumference of a circle is given by the formula C = πd, where C is the circumference, π (Pi) is approximately 3.14159, and d is the diameter of the circle. Given that the circumference of the circle is 34π, we can find the diameter by dividing the circumference by π:

d = C / π = 34π / π = 34

Therefore, the diameter is 34 units. The radius r is half of the diameter, so:

r = d / 2 = 34 / 2 = 17

Thus, the radius of the circle is 17 units.
