hi, Im offering 50 points for this one, Pls help me, I need an explanation and a answer
Answer:24/8 cups of water
Step-by-step explanation:
I think u just add it up like, 1/8. there were 6 people that did 1/8 so 6/8 cups. or 3/4.
then 2 people did 1/4 so, that is 2/4, or 1/2. so currently 5/4 cups of water.
3 people did 3/8, so 9/8. 10/8 plus 9/8=19/8
19/8plus 5/8 = 24/8.
i dont know if correct but still try on ur own.
Answer:
(1/8*6)+(1/4*2)+(3/8*3)+5/8=
3/4+1/2+1 1/8+5/8=
6/8+4/8+1 1/8+5/8=24/8
24/8=3

Step-by-step explanation:
Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

A trapezoid was broken into a triangle and rectangle.
The area of the rectangle is cm2.
The area of the triangle is cm2.
The area of the trapezoid is cm2.
Answer:
Step-by-step explanation:
Base x Height = Area
10x12=120 the area of the rectangle is 120
area of the triangle is 28
sorry but I don't know the trapezoid
The area of the rectangle is 120 cm².
The area of the triangle is 24 cm².
The area of the trapezoid is 144 cm².
What is a trapezoid?An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.
A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.
The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.
We know, the area of a triangle is (1/2)×base×height and the area of a rectangle is (length×width).
Therefore, From the given information,
The area of the triangle is, (1/2)×4×12 = 24cm².
And the area of the rectangle is, (10×12) = 120 cm².
Therefore, The area of the trapezoid is,
= (24 + 120) cm².
= 144 cm².

Match the terms to their definition. 1 . a number that is less than zero positive number 2 . a number belonging to the set made up of the counting numbers: 1, 2, 3, and so on integer 3 . a number that is greater than zero negative number 4 . a number belonging to the set made up of the whole numbers and their opposites opposite numbers 5 . a line that graphically represents all numbers natural number 6 . two numbers that are the same distance from zero on the number line, but in opposite directions number line
Answer: 1. Negative number
2. Natural number
3. Positive number
4. Integers
5. Number line
6. Opposite numbers
Step-by-step explanation:
1. The first statement says a number that is less than zero, which means any negative number would be less than zero. For example (-1), (-2), etc.
2. The second statement is asking for numbers belonging to the counting set, which means starting from one (1). Natural numbers are numbers that start from 1 and don't include negative numbers or zeros.
3. The third statement says the number that is greater than zero, as negative numbers are smaller than zero and the natural number option has already been chosen above, we will consider positive numbers.
4. Whole numbers consist of both negative and positive integers including zero. Therefore, a set of whole numbers will be written as integers.
5. Number line is a line that represents both negative and positive numbers.
6. Consider an example- (+5) and (-5), both the numbers are the same but with different signs, making them opposite of each other. Therefore, the correct answer would be opposite numbers.
Find the height and area of an equilateral triangle with side lengths of 10 cm.
Height:____cm
Area:______cm²
PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
\(Area = 25\sqrt{3}\)
\(Height = 5\sqrt{3}\)
To find the height and area of an equilateral triangle we can start by finding the area using the following equation
\(Area =\frac{\sqrt{3}}{4} side^2\\Area =\frac{\sqrt{3}}{4} 10^2\\Area =\frac{\sqrt{3}}{4} 100\\\)
Which then simplifies down to
\(Area = 25\sqrt{3}\)
Next, we can find the height using the following equation
\(Height = \frac{side\sqrt{3} }{2} \\Height = \frac{10\sqrt{3} }{2}\)
which then simplifies down to
\(Height = 5\sqrt{3}\)

HELP ASAP!! A student is painting a brick for his teacher to use as a doorstop in the classroom. He is only painting the front of the brick. The vertices of the face are (−4, 2), (−4, −11), (4, 2), and (4, −11). What is the area, in square inches, of the painted face of the brick?
A. 42 in2
B. 52 in2
C. 104 in2
D. 128 in2
Answer:
104in2
Step-by-step explanation:
The area, in square inches, of the painted face of the brick is Option C 104 \(in^{2}\).
Using the Quadrant system of the Number line
B (-4,2) lies in the 2nd quadrant.
C (-4,-11) lies in the 3rd quadrant
A (4,2) lies in the 1st quadrant
D (4,-11) lies in the 4th quadrant
Length of Side AB= Length of Side CD= Distance between x coordinate of A & B OR Between C & D i.e. 8 in
Length of Side BC= Length of side AD= Distance between y coordinate of A & D OR Between B & C i.e. 13 in
Area of the Square ABCD= (length of Side AB or CD) X (Length of Side BC or AD)
= (8 x 13) \(in^{2}\)
= 104 \(in^{2}\)
Thus, Area of square is 104 \(in^{2}\).

Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
Food Express is running a special promotion in which customers can win a free gallon of milk with their food purchase if there is a star on their receipt. So far, 219 of the first 264 customers have not received a star on their receipt. So far, 147 of the 156 costumers have not received a star on their receipts. What is the experimental probability someone will win a free gallon of milk?
Answer:
3/52
Step-by-step explanation:
The experimental probability of winning a free gallon of milk will be calculated as under -
It is given that, total number of outcomes = 156
Non-winning customers = 147 (it is given in the question)
Thus, the winning customers will be = Total outcomes - Non-winning customers
Expected winning customers = 156 - 147 = 9
The probability is calculated as -
Probability (Winning customer) = winning customers/total customers
Probability (Winning customer) = = 9/156 = 3/52
