Joanne is making punch. She uses 1/2 gallon of orange juice, 3 quarts of lemonade, and 1 1/4 gallons of apple cider. How many quarts of punch will she have all together?
Answer:
10 Quarts
Step-by-step explanation:
First, convert 1/2 gallons into quarts. 1/2x4=2. Then convert 1 1/4 to quarts. 1 1/4x4=5. Finally, add it all togher. 2+5+3=10. So, the answer is 10 quarts.
-5x2-7x2
the twos are the squared.
Answer:
-12x²
Step-by-step explanation:
Given expression:
[tex]-5x^{2} -7x^{2}[/tex]
Since both terms in the expression have common terms, we can subtract the terms by combining like terms.
[tex]\implies x^{2} (-5 -7)[/tex]
[tex]\implies x^{2} (-12)[/tex]
[tex]\implies -12x^{2}[/tex]
Which are the foci of the hyperbola represented by 5x2 – 4y2 + 80 = 0?
Step-by-step explanation:
[tex]5 {x}^{2} - 4 {y}^{2} + 80 = 0[/tex]
[tex]5 {x}^{2} - 4 {y}^{2} = - 80[/tex]
[tex] - \frac{ 5{x}^{2} }{16} + \frac{ {y}^{2} }{20} = 1[/tex]
[tex] \frac{ {y}^{2} }{20} - \frac{5 {x}^{2} }{16} = 1[/tex]
To find foci,
[tex]c = \sqrt{ {a}^{2} + b {}^{2} } [/tex]
so
[tex]c = \sqrt{20 + 16} [/tex]
[tex]c = \sqrt{36} [/tex]
[tex]c = ±6[/tex]
Since the y term has a greater denomiator, our foci is
(0,6) and (0,-6)

Find the measure of x.
Hint: Use the Pythagorean Theorem. If the diameter is 32, then the radius is half of it.
Answer:
18.36 to nearest hundredth.
Step-by-step explanation:
base of the triangle = 1/3 * 32 = 16.
x^2 = 9^2 + 16^2
x^2 = 81 + 256 = 337
x = √337 = 18.36.

Do you think it is okay that social media companies make users agree to let them use users’ photos? Why or why not?
Compare what you think about social media companies using users’ photos to people claiming photos they found online as their own. Is one practice worse than the other? Why or why not?
Write one to two sentences explaining what you think about social media companies requiring users to agree to the company using their images for promotional purposes. Provide at least one reason that supports your idea.
Write two to three sentences comparing people claiming photos they found online as their own to social media companies using user images. Provide at least one reason that supports your idea.
Answer:

On the other hand...
no matter if it's on the agreement if it is inappropriate on your part it is illegal and you can complain.
The angles shown are supplementary What is
the value of x One angle is 3x and the other is 96
Answer:
x = 28
Step-by-step explanation:
Supplementary angles mean that both angles are equal to 180. So, the equation becomes 3x + 96 = 180. Solving for x, we get 28.
Answer:
The value of x is 28
Step-by-step explanation:
Given :
Angles are supplementary One angle = 3xOther angle = 96Now,
Supplementary angles are a pair of angles that make sum of 180° .
Therefore, The sum of given angles will be equal to 180°.
i.e. one angle + other angle = 180°
Substituting the values of angles , we get..
[tex]⇢3x + 96 = 180[/tex]
[tex]⇢3x = 180 - 96[/tex]
[tex]⇢3x = 84[/tex]
[tex]⇢x = \frac{84}{3} [/tex]
[tex]⇢ \boxed{x = 28}[/tex]

Answer:

Answer:
Answer:
Expression equivalent to (k + k)(4) is 28.
Step-by-step explanation:
Given:
k(x) = 5x - 6
We need to find an expression equivalent to (k + k)(4)
First, we find,
(k + k)(x) = k(x) + k(x)
= ( 5x - 6 ) + ( 5x - 6 )
= 5x - 6 + 5x - 6
= 5x + 5x - 6 - 6
= 10x - 12
Now, (k + k)(4) = 10(4) - 12 = 40 - 12 = 28
Therefore, the Expression equivalent to (k + k)(4) is 28.

the pre image of a line has the equation y=-7x. this line is translated -5 units along the x-axis and the 8 units along the y-axis. which is the equation of the image of this line?
ill mark you brainliest if youre right
Answer:
(b) y = -7x -27
Step-by-step explanation:
When x and y in the equation y = f(x) are replaced by (x-h) and (y-k), the function graph is translated h units right and k units up. The translated function can be written as ...
y -k = f(x -h)
y = f(x -h) +k . . . . . . add k
__
Your function is ...
y = -7x
and you want to translate it by (h, k) = (-5, 8). That makes it ...
y' = -7(x -(-5)) +8 = -7x -35 +8
y' = -7x -27

Answer:
x = 23 y =67
Step-by-step explanation:
Since a rectangle is made up of 4 right angles you can solve y with the following equation:[tex]23 + y =90[/tex]
Then to solve for x, since x, y and the right angle makes up a triangle and a triangle has 180 degrees. You can use the following equation to solve for x:
[tex]x + 67 + 90 = 180[/tex]
A golf ball is hit so that it travels a horizontal distance of 400 feet and reaches a
maximum height of 190 feet.
Determine a quadratic equation that models the path of the golf ball, assuming it starts at the origin.
Considering the vertex, the quadratic equation that models the path of the golf ball is given by:
y = -0.0011875(x - 400)² + 190
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In this problem, the vertex is at the maximum height of the parabola, given by (400, 190), hence h = 400, k = 190, and:
y = a(x - 400)² + 190
It starts at the origin, that is, when x = 0, y = 0, hence:
0 = 400²a + 190
a = -190/400²
a = -0.0011875.
Hence, the equation is:
y = -0.0011875(x - 400)² + 190

subtract 19 from both sides to isolate x
8x=120
divide both sides by 8
8x/8=120/8

how do i round 0.942 to the nearest tenth!!
Answer: 0.9
Step-by-step explanation: All you need to just keep your decimal (0.9) as it is since 4 and 2 are below 5 then you don't need to round it higher. I hope this helped!
0.942
to find:the nearest tenth of 0.942
solution:to round to the nearest tenth, if the number in hundredths place is 5 or more you'll have to round up, if not keep it as it is and remove all the digits in the right side.
=0.9
hence, the nearest tenth of 0.942 is 0.9
