Earl needs to fill juice cups for his little brother's birthday party. There are 25 juice cups and each juice cup holds 12 fluid ounces. The juice comes in 1-gallon bottles. How many 1-gallon bottles of juice will Earl need to purchase? (2 points) (1 quart = 32 fluid ounces, 1 gallon = 4 quarts) 1 bottle 2 bottles 3 bottles 4 bottles
Answer:
3 bottles
Step-by-step explanation:
Hello!
First, we find out how many fluid ounces 25 cups of juice hold.
One cup holds 12 fluid ounces so to find 25 we do
25 * 12 = 300 fluid ounces
Next, we find out how many fluid ounces one gallon holds.
One gallon is 4 quarts.
1 quart is 32 fluid ounces so to find how many 4 holds we do
32 * 4 = 128
So one gallon holds 128 fluid ounces
To find how many we need we divide the total needed by how much one bottle holds
300/128 = 2.34
You can't buy exactly 2.34 bottles of juice so we round up to the nearest whole number we will just have extra leftover
The answer is 3 bottles

Look at the triangle ABC. What is the length of the side AB of the triangle? A.) 3 B.) 5 C.) Square root of 6 D.) Square root of 13
Answer:
The answer is option DStep-by-step explanation:
To find the length of AB we use the formula
[tex] \sqrt{ ({x _{1} - x_{2}})^{2} + ({y_{1} - y_{2} })^{2} } [/tex]
Where
(x1 , y1) and (x2 , y2) are the points
From the question
A is (4 , 5) B is (2 , 2)
So the length of AB is
[tex] |AB| = \sqrt{ ({4 - 2})^{2} + ({5 - 2})^{2} } [/tex]
[tex] |AB| = \sqrt{ {2}^{2} + {3}^{2} } [/tex]
[tex] |AB| = \sqrt{4 + 9} [/tex]
We have the final answer as
[tex] |AB| = \sqrt{13} [/tex]

x=9
Answer:
2
Step-by-step explanation:
This is our equation-
-4(2x-1)=-6(x+2)
We are trying to isolate x in a side, but first, we must multiply the numbers in between the brackets. A negative number multiplied by a positive number gives a negative number, and a negative times a negative is positive, so-
-8x·4=-6x+(-12)
Now we have to multiply -8x times 4
-32x=-6x-12
Now we isolate x-
-24x=-12
We divide and get the final result of x=2
x=2
Solve the equation 58 - 10x ≤ 20 + 9x
Answer:
x≥2
Step-by-step explanation:
First, write out the equation as you have it:
[tex]58-10x\leq20+9x[/tex]
Then, add [tex]10x[/tex] to both sides:
[tex]58-10x+10x\leq20+9x+10x\\58\leq20+19x[/tex]
Next, subtract [tex]20[/tex] from both sides:
[tex]58-20\leq20-20+19x\\38\leq19x[/tex]
Finally, divide both sides by [tex]19[/tex]:
[tex]\frac{38}{19}\leq\frac{19x}{19}\\2\leq x[/tex]
or
[tex]x\geq 2[/tex]
Therefore: the answer to this inequality/equation is: x≥2

The four angles in a quadrilateral are in the ratio 2:5:6:7. Find the smallest angle in the quadrilateral?
Answer:
36º
Step-by-step explanation:
Since all the angles are in a ratio, and all angles add up to 360º, we can set up a simple equation to find the smallest angle.
2x + 5x + 6x + 7x = 360
20x = 360
x = 18
18 is NOT the answer since the smallest angle has a ratio number of 2. So we multiply 18 with 2 to get 36º.

Answer:
36
Step-by-step explanation:
The four angles of a quadrilateral add to 360
2:5:6:7
Multiply by x
2x:5x:6x:7x
Add them together to get 360
2x+5x+6x+7x = 360
20x = 360
Divide each side by 20
20x/20 = 360/20
x =18
The smallest angle is 2x
2*18 = 36
What is the value of x?
Answer:
x = 28
Step-by-step explanation:
Given a line parallel to a side of a triangle and intersecting the other 2 sides, then it divides the sides proportionally, that is
[tex]\frac{AC}{CR}[/tex] = [tex]\frac{AD}{DR}[/tex] , substitute values
[tex]\frac{10}{x}[/tex] = [tex]\frac{15}{42}[/tex] ( cross- multiply )
15x = 420 ( divide both sides by 15 )
x = 28

Just took quiz.
Based on the calculations, the volume of this pyramid is equal to: D. 324 cm³.
Given the following data:
Base area = 54√3 cm².Edge length = 6 centimeters.Angle BAC = 60°.How to calculate the volume of a pyramid?Mathematically, the volume of a pyramid can be calculated by using this formula:
Volume = 1/3 × base area × height
Next, we would find the height of this pyramid from the right-angled triangle ABC by applying Tan trigonometry formula:
Tanθ = Opp/Adj = BC/AC
Tan60 = height/6
√3 = height/6
Height = 6√3 cm.
Now, we can calculate the volume of this pyramid:
Volume = 1/3 × base area × height
Volume = 1/3 × 54√3 × 6√3
Volume = 1/3 × 972
Volume = 324 cm³.

fives times a number and the difference of 6
Answer: The equation that has resulted from this is 5x - 6.
Step-by-step explanation:
So far, we know that the givens are:
fives times a number and the difference of 6
Then, we can conclude that the term "a number" means an unknown term, so all we have to do is put a variable in its place. It can be k, s, h, z, x, etc. Next, just find the difference of 6. So, from what we know, this is what our new equation looks like:
5 times ( a number) - the difference of 6
In math form:
5 (x) - 6
Simplify:
5x - 6
Hence the answer!

[tex]\Huge \boxed{{x=56\°}}[/tex]
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Create an equation.
64 + x + 60 = 180
Solve for x.
Add the numbers.
x + 124 = 180
Subtract 124 from both sides.
x + 124 - 124 = 180 - 124
x = 56
Answer:
56°
Step-by-step explanation:
64 + 60 = 124180 - 124 = 56Why?
We did 64 + 60 because they are the two degrees that is given to us, and those two added with x will give us 180.When we add 64 and 60 together, we get 124. We then subtract that total from the total of the three angles to give us the remaining angle., which is 56.Therefore, x is 56°

On a map, 1/4 inch between locations represents an actual distance of 2 miles between the locations. What is the actual distance, in miles, between the two cities that are 3 3/4 inches apart on the map?
Answer:
30 miles
Step-by-step explanation:
1/4 = 2
3 3/4 = x
15/4 = x
So, Cross multiply
=> 1/4 * x = 15/4 * 2
=> 1/4x = 15/4 * 4/2
=> 1/4x = 60/8
=> 1/4x = 7.5
=> 1/4x * 4 = 7.5 * 4
=> x = 30
So, 15/4 inches on the map equals 30 miles.
