For the school’s sports day, a group of students prepared, 21 1/2 liters of lemonade. At the end of the day, they had 258 liters left over. How many liters of lemonade were sold?
Answer:
83 (maybe)
Step-by-step explanation:
21 1/2 = (actual number) = 21,500
(left over = 258 ÷ 21,500 or 21,500 ÷ 258)
21,500 ÷ 258 = 83
So, the answer is 83.
I'm not entirely sure if my answer is correct.
Sorry if it's wrong.

find the areas of the trapezoid
Answer:
Formula for the area of a trapezoid;
A = 1/2 (b1 + b2) x h
Where b1 represents base one, and b2 is base two. And H displays as the height.
First, we must figure out our bases and then our height.
If we look at the trapezoid, we can see the bottom base(which will be our base 1) is 4. Our upper base is 2, which we will consider our base 2.
Our height is 4, because the distance between our bases is 4.
So now we plug these values into our formula;
A = 1/2 (b1 + b2) x h
A = 1/2 (4 + 2) x 4
Now solve:-
A = 1/2(6) x 4
A = 6/2 x 4
A = 3 x 4
A = 12
Answer:
48 inches
Step-by-step explanation:
It is going by 2 so when you look at the lines inside the shape going up and down you see 4 lines. 4 times 2=8( because it is going by 2). Then you see the lines in the shape going horizontal it states 2 lines is equal to 2 so then you do 2 times 2=4(because it is going by two). You then do 8 times 4=32 and 8 times 2=16 32+16=48. I go to RSM too so trust me this is correct.

Solution:
To find the area of a composite shape, we need to break the composite shape into smaller "known" shapes.
⇒ Area of composite figure = Area of quarter circle + Area of all rectangles...Step-1: Find the radius of the quarter circle
Radius of quarter circle = (8 + 4 + 4) - (9)Radius of quarter circle = (16) - (9)Radius of quarter circle = 7 metersStep-2: Find the area of the quarter circle (Q)
Area of circle = πr²Area of quarter-circle = πr²/4Area of quarter-circle = (3.14)(7²)/4Area of quarter-circle = (0.785)(49)Area of quarter-circle = 38.465 m²Step-3: Find the area of rectangle₁ (L)
Area of rectangle = LBArea of rectangle₁ = (21)(8)Area of rectangle₁ = 168 m²Step-4: Find the area of rectangle₂ (M)
Area of rectangle = LBArea of rectangle₂ = (4 + 4)(21 - 18)Area of rectangle₂ = (8)(3)Area of rectangle₂ = 24 m²Step-5: Find the area of rectangle₃ (S)
Area of rectangle = LBArea of rectangle₃ = (4)(8)Area of rectangle₃ = 32 m²Step-6: Find the area of the composite figure.
Area of composite figure = Area of quarter circle + Area of all rectangles...Area of composite figure = 38.465 + (168 + 24 + 32)Area of composite figure = 262.465 m²HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLPPPPPPP

Answer:
I'm think the first one is an answer, but I don't know about the rest.
Step-by-step explanation:
x = -4, x = -4, x = 2, x = 4.
And there are two sides that equal to 8. one side that equals 6, and a 4 side.
The expressions that represent the area of the quadrilateral shown is first and last options.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given is a quadrilateral.
This can be divided into known quadrilaterals to find the area.
This can be done in two ways as shown in the image below.
Area of rectangle/square = Length × Width
Area of triangle = [tex]\frac{1}{2}[/tex] × base × height
As shown in the first figure,
Area of the quadrilateral ADGH = Area of rectangle ABCD - Area of ΔABH - Area of ΔGHE - Area of square GECF - Area of ΔFGD.
Area = (8 × 8) - ([tex]\frac{1}{2}[/tex] × 8 × 2) - ([tex]\frac{1}{2}[/tex] × 2 × 4) - (2 × 2) - (([tex]\frac{1}{2}[/tex] × 6 × 2)
This is the first option.
As shown in the second figure,
Area of quadrilateral GFBE = Area of ΔGDF + Area of ΔBCF + Area of rectangle ABCD + Area of ΔABE
Area = ([tex]\frac{1}{2}[/tex] × 8 × 2) + ([tex]\frac{1}{2}[/tex] × 2 × 4) + (6 × 4) + ([tex]\frac{1}{2}[/tex] × 6 × 2)
This is the last option.
Hence the area of the quadrilateral can be either first or last option.

James is tracking the changes in barometric pressure (measured in inches of mercury – inHg) for his science class. On Monday the pressure was 30.01inHg. The pressure dropped by 0.34 inHg on Tuesday, before climbing 1.32 inHg on Wednesday. What was the barometric pressure reading for Wednesday?
Answer:
30.99 inHg.
Step-by-step explanation:
First, subtract how much the pressure dropped on Tuesday from Monday's reading. 30.01 inHg - 0.34 inHg = 29.67 inHg
Then, add how much the pressure climbed on Wednesday to Tuesday's reading. 29.67 inHg + 1.32 inHg = 30.99 inHg
Answer:
The barometric pressure reading for Wednesday was 31.01inHg. This can be calculated by subtracting 0.34inHg from the pressure reading on Monday (30.01inHg) and then adding 1.32inHg, which results in 31.01inHg.

On a piece of paper, use a protractor to construct a triangle with angle measures of 50° and 40°.
Which statements about this triangle are true?
Select all correct answers.
The third angle measures 110°.
The third angle measures 50°.
Two sides have the same length.
The third angle measures 90°.
All sides have different lengths.
Answer:
the sentences that are true are..:
Two sides have the same length
The third angle measures 70°
It is an acute triangle.
i know that because eat triangle is 180°, so if we subtract 40° and 70° from 180°, we get 70°, meaning the three angles in the triangle are 40°, 70°, and 70°. Because all of the angles are under 90°, we know that it is an acute triangle.
The answers are (d) The third angle measures 90° and (e) All sides have different lengths.

5w–10>20 ; with the given set → {5,6,7,8}
its for an assignment
Answer:
w = 7, and w = 8 is correct
Step-by-step explanation:
1. Why 5 does not work
a. Substitute 5 into the equation
5w-10>20 --> 5(5) - 10 > 20
b. Solve the equation
Remember Pemdas:
P- Parentheses First
E- Exponents Second
M- Multiplication Third
D- Division Fourth
A- Addition Fifth
S- Subtraction Sixth
We are not working with Exponents and Parentheses, but we are working with the rest.
Since there is no P and E, that means that multiplication is first
5(5)-10>20 - 5(5) = 5 x 5 = 25
Now all is left is to subtract:
25 - 10 = 15
15 > 20 Is not true.
2. Why 6 does not work
a. Substitute
5w-10>20 --> 5(6) - 10 > 20
b. Solve
5(6) = 5 x 6 = 30
30 - 10= 20
20 > 20 is not true
Just like you are not greater than yourself, 20 can not be greater than its own self.
3. Why 7 and 8 work (7a, 7b is 7; 8a, 8b is 8)
7a. Substitute
5w-10>20 --> 5(7) - 10 > 20
8a. Substitute
5w - 10 >20 --> 5(8) - 10 > 20
7b. Multiply and subtract
5(7) = 5 x 7 = 35
35 - 10 = 25
25 > 20
25 is greater than 20
8b. Multiply
5(8) = 5 x 8 = 40
40 - 10 = 30
30 > 20
30 is greater than 20
Hereby, w = 7, and w = 8

Milan uses a probability simulator to roll a six-sided number cube 100 times and to flip a coin 100 times. The results of the experiment are shown below:
Number on the Cube Number of Times Rolled
1 10
2 8
3 33
4 29
5 11
6 9
Heads Tails
29 71
Using Milan's simulation, what is the probability of rolling a 5 on the number cube and the coin landing on tails?
fraction 11 over 10,000
fraction 71 over 10,000
fraction 82 over 10,000
fraction 781 over 10,000
Answer:
781/10000
Step-by-step explanation:
These are independent events so we can multiply the probabilities
P(5 on the coin ) = 11/100
P( tail on the coin) = 71/100
P( 5 and tails) = 11/100 * 71/100
= 781/10000
Answer:
the probability of rolling a 5 on the number cube and the coin landing on tails is 781 over 10,000
Step-by-step explanation:
T= 71 times
11= 5 rolled
71/100 * 11/100 = 781/10000

Step-by-step explanation:
A geologist visits 40 volcanoes in Alaska and California. 15% of the volcanoes are in California.
How many volcanoes does the geologist visit in California and how many in Alaska?
Answer:
Most explained:40% = 100%
15 = (100% - 15% = 85%) 85% in Alaska
California = 15% of 40 = (0.15 x 40) = 6
Alaska = 85% of 40 = (0.85 x 40) = 34
The simple way (or the way i found it simple):40 - 15 = 3415% of 40 = 6(I found the simple way after i solve the first way)

Step-by-step explanation:
Equation to remember:
Length · Width · Height = Volume
LWH = V
-------------------------------------------------
In this word problem, you can find that we're missing the height aspect of the equation. Your equation would look something like this:
[tex]12 * 10 * h = 1800[/tex]
-------------------------------------------------
Work:
[tex]12 * 10 * h = 1800\\\\120h = 1800\\\\\frac{120h}{120} = \frac{1800}{120}\\\\h = 15[/tex]
-------------------------------
As you can see, the height of our rock is 15cm.
