Hal says the volume of the sphere shown below is 36 cm3. Find the correct volume, using 3.14 for π. Round to the nearest hundredth. What was Hal’s likely error?
This question is incomplete because the diagram of the sphere was not shown. Find attached to this answer the diagram for the sphere.
Answer:
a) The correct volume of the sphere = 113cm³
b) b) Hal's likely error was that
i) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)
ii) In addition to using the wrong formula, Hal did not use π in his calculation.
Step-by-step explanation:
a) The Volume of a Sphere = 4/3πr³
From the attached diagram, the radius of the sphere was given as = 3cm
π = 3.14
The volume of the sphere = 4/3 × 3.14 × 3³
= 113.04 cm³
We were told to round up to the nearest hundredth. Therefore, correct the volume of the sphere = 113cm³.
b) Hal's likely error was that
i) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)
ii) In addition to using the wrong formula, Hal did not use π in his calculation.
This means:
Surface Area of a Sphere = 4πr²
But Hal's used = 4r²

Jimena draws a figure with two pairs of parallel opposite sides. The four sides are not all the same length, and the figure has no right angles. Which two figures could she have drawn?
Answer:
Parallelogram
Step-by-step explanation:
we will solve question using hints given in question
given
There two pairs of parallel opposite sides
1. since there are two pairs of it means there 4 sides so the figure is quadrilateral
there are six possible types of quadrilateral possible
rectangle, square, rhombus, parallelogram, kite or any irregular quadrilateral which has not any standard defined shape
2 . It is given that opposite sides are parallel
there are four such quadrilateral which have opposite side parallel
rectangle, square, rhombus, parallelogram
Thus these are possible figures
3. Four sides are not all the same length
Since square and rhombus have all the sides of same length thus we omit these probable figure
hence probable figure left are
rectangle, parallelogram
4. figure has no right angles
since rectangle has right angle so it will also be omitted from the probable figure
Hence only probable figure left is parallelogram.
Parallelogram is a quadrilateral with two two pairs of parallel opposite sides
and satisfying the above condition of
1. The four sides of not the same length
2. no right angles
Find the volume of a pyramid with a square base, where the side length of the base is 6.6\text{ in}6.6 in and the height of the pyramid is 7.7\text{ in}7.7 in. Round your answer to the nearest tenth of a cubic inch.
The correct answer is:
The volume of the pyramid is approximately 111.5 cubic inches, rounded to the nearest tenth of a cubic inch.
To find the volume of a pyramid, we can use the formula:
[tex]\[ \text{Volume} = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]
Given:
- Side length of the square base = 6.6 inches
- Height of the pyramid = 7.7 inches
First, let's find the area of the square base:
[tex]\[ \text{Area of square base} = \text{Side length}^2 \]\[ = 6.6^2 \]\[ = 43.56 \text{ square inches} \][/tex]
Now, substitute the values into the formula for the volume of a pyramid:
[tex]\[ \text{Volume} = \frac{1}{3} \times 43.56 \times 7.7 \]\[ \text{Volume} = \frac{1}{3} \times 334.632 \]\[ \text{Volume} = 111.544 \text{ cubic inches} \][/tex]
Rounding to the nearest tenth, the volume of the pyramid is approximately [tex]\( \boxed{111.5} \)[/tex] cubic inches.
The volume of the square-based pyramid is calculated using the formula for the volume of a pyramid, resulting in approximately 111.8 cubic inches after rounding to the nearest tenth.
The volume of a pyramid with a square base is calculated using the formula V = (1/3) x base area x height. First, calculate the base area, which is the side length squared. In this case, the base area is:
6.6 in x 6.6 in = 43.56 in²
Then, multiply the base area by the height and divide by 3 to find the volume:
V = (1/3) x 43.56 in² x 7.7 in
= 43.56 in² x 2.566 in
= 111.804 in³, which rounds to 111.8 in³ to the nearest tenth.
Therefore, the volume of the square-based pyramid is 111.8 in³.

How do you write 13/20 as a decimal? ( Hint: Find the factor that will make the denominator 100 and multiply that factor to the given numerator and change it to decimal form.)
Answer:
0.65
Step-by-step explanation:
To get 13/20 to a decimal, the denominator needs to be multiplied by 5 to make it 100. If you multiply the denominator, you also have the multiply the numerator to make it equal. 13 x 5 is 65. The fraction is 65/100, which is 0.65 in decimal form.
13/20 as a decimal is 0.65.
To write 13/20 as a decimal, you can follow the hint provided.
First, we need to find a factor that will make the denominator 100. In this case, multiplying the denominator by 5 will give us 100.
So, we need to multiply both the numerator and the denominator of 13/20 by 5:
13/20 x 5/5 = 65/100
Now, we have 65/100 as the fraction.
To convert it to decimal form, divide the numerator by the denominator:
65 ÷ 100 = 0.65
Therefore, 13/20 as a decimal is 0.65.

Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted:
Write an equation to determine the area, A, of the patio that will be painted.
A = (x + 20)(x + 10) + 12
A = (x + 20)(x + 10) − 12
A = (x + 26)(x + 12)
A = (x + 14)(x + 8)
Answer:
A = (x + 15)(x + 10) − 5
Step-by-step explanation:

How many ways can the letters in the word D-I-N-O-S-A-U-R be arranged?
The letters in the word D-I-N-O-S-A-U-R can be arranged in 40,320 ways.
Explanation:To find the number of ways the letters in the word D-I-N-O-S-A-U-R can be arranged, we can use the concept of permutations.
The word D-I-N-O-S-A-U-R contains 8 different letters. To find the number of arrangements, we can use the formula for calculating permutations of n objects taken all at a time, which is n!. In this case, n is equal to 8, so the number of arrangements is 8!.
However, there are some repeated letters in the word D-I-N-O-S-A-U-R.
The letter 'A' is repeated twice. To account for the repetition, we divide the total number of arrangements by the factorial of the number of times each repeated letter occurs.
In this case, 'A' appears twice, so we divide by 2!. So the final answer is 8! / 2!.
Simplifying the expression, we have 8! / 2! = 40,320.

A worker at a mill is loading 10-lb bags of flour into boxes to deliver to a local warehouse. Each box holds 4 bags of flour. If the warehouse orders 2 tons of flour, how many boxes are needed to fulfill the order?
Answer: 100 boxes
Step-by-step explanation:
Hi, since 1 ton = 2,000 lbs
We have to divide 10lbs by 2000 to convert the lbs in tons.
1t/2000lb = xt / 10lb
10 /2000=0.005
0.005 ton = 10 lbs (1 bag)
Each box has 4 bags
0.005 ton x 4 = 0.02 ton
So each box weights 0.02 ton
Since we need 2 tons.
Using proportions:
0.02t/1 box= 2 t / x boxes
x = 2 / (0.02/1)
x = 100 boxes

An Archaeologist in Turkey discovers a spear head that contains 79% of its original amount of C-14. Find the age of the spear head to the nearest year.
Answer:
The age of the spear head is of 1938 yers.
Step-by-step explanation:
The amount of carbon 14 after years is given by the following equation:
[tex]Q(t) = Q(0)e^{-rt}[/tex]
In which Q(0) is the initial amount and r is the decay rate.
The half life of carbon 14 is 5700 years.
This means that [tex]Q(5700) = 0.5Q(0)[/tex]
So
[tex]Q(t) = Q(0)e^{-rt}[/tex]
[tex]0.5Q(0) = Q(0)e^{-5700r}[/tex]
[tex]e^{-5700r} = 0.5[/tex]
[tex]\ln{e^{-5700r}} = \ln{0.5}[/tex]
[tex]-5700r = \ln{0.5}[/tex]
[tex]5700r = -\ln{0.5}[/tex]
[tex]r = -\frac{\ln{0.5}}{5700}[/tex]
[tex]r = 0.00012160476[/tex]
So
[tex]Q(t) = Q(0)e^{-0.00012160476t}[/tex]
We have to find:
t for which Q(t) = 0.79Q(0). So
[tex]Q(t) = Q(0)e^{-0.00012160476t}[/tex]
[tex]0.79Q(0) = Q(0)e^{-0.00012160476t}[/tex]
[tex]e^{-0.00012160476t} = 0.79[/tex]
[tex]\ln{e^{-0.00012160476t}} = \ln{0.79}[/tex]
[tex]-0.00012160476t = \ln{0.79}[/tex]
[tex]0.00012160476t = -\ln{0.79}[/tex]
[tex]t = \frac{-\ln{0.79}}{0.00012160476}[/tex]
[tex]t = 1938.43[/tex]
Rounding to the nearest year.

Step-by-step explanation:
Final answer:
A graph that displays a collection of ordered pairs is known as a scatter plot, which shows the relationship between two variables using a Cartesian coordinate system.
Explanation:
A graph that displays a collection of ordered pairs is called a scatter plot. A scatter plot, also known as a scatter diagram, uses Cartesian coordinates to display values for two variables. It is a pictorial representation of the relationships of quantitative data, presenting individual points where the value of one variable determines the position on the horizontal axis (x-axis), and the value of the other variable determines the position on the vertical axis (y-axis). The pattern of these points on the graph helps to visualize any correlation between the variables being analyzed.

What is the y-intercept of the line given by the equation y= 3x + 4?
Answer:
the y intercept is 4
Step-by-step explanation:
the 4 is where the line starts so it would be (0,4)
First, notice that this equation is written in slope-intercept form which is more commonly known as y = mx + b form where the multiplier, m, or the coefficient of the ex term represents the slope of the line and the b or the constant term represents the y-intercept of the line.
I have attached slope-intercept form below.
Notice that below, the b is in place of the 4 in the equation.
So the y-intercept or the b is 4.

During a figure skating routine, Jackie and Peter skate apart with and angle of 15 degrees between them. Jackie skates for 5 meters, and Peter skates for 7. How far apart are the skaters?
Answer:
The skaters are 2.5 feet apart
Step-by-step explanation:
Firstly, please check attachment for diagrammatic representation.
To calculate the distance apart, this is same as the length PJ
To calculate this length, we can use the cosine rule as follows;
O^2 = P^2 + J^2 -2(P)(J)Cos 15
O^2 = 7^2 + 5^2 -2(7)(5)Cos 15
O^2 = 49 + 25 - 70Cos15
O^2 = 74 - 67.61
O^2 = 6.39
O = √6.39
O = 2.53
O = 2.5 feet to the nearest tenth of a foot
The distance between the skaters is 2.5m
Data;
Jackie (a) = 5mPeter (b) = 7mangle = 15 degreesdistance apart = cCosine RuleTo solve this problem we can use cosine rule for this since we have the value of two sides and an angle.
[tex]c^2 = a^2 + b^2 -2ab cos C[/tex]
Let's substitute the values into the formula
[tex]c^2 = 5^2 + 7^2 - 2*5*7*cos15\\c^2 = 25 + 49 - 67.61\\c^2 = 6.39\\c = \sqrt{6.39} \\c = 2.5m[/tex]
The distance between the skaters is 2.5m

Answer:
86
Step-by-step explanation:
Given that there are 30 students in class 10R and the mean marks for the entire class was 70%. Therefore, total mark of class = 70 x 30 = 2100
Given that there are 20 boys in the class and the mean marks for the boys was 62 %. Therefore, total mark of boys = 62 x 20 = 1240
To calculate the mean mark for the girls we need to find the total number of girl and total mark of girls. total number of girl = 30 - 20 (boys) = 10 total mark of girls = total mark of class - total mark of boys = 2100 - 1240 = 860 mean mark for girls = 860 / 10 = 86

A jar contains 4 red marbles, 3 green marbles, and 2 blue marbles. If a marble is drawn at random, what is the probability that it is not green?
Answer:
6/9
Step-by-step explanation:
The probability of drawing a marble that is not green from a jar with 4 red, 3 green, and 2 blue marbles is 2/3 or 66.67%.
To find the probability of drawing a non-green marble from a jar containing red, green, and blue marbles, calculate the ratio of non-green marbles to the total marbles
Calculate the total number of marbles: 4 (red) + 3 (green) + 2 (blue) = 9 marbles in total.
The probability of drawing a non-green marble = [tex]\frac{(4~ red ~marbles + 2 ~blue ~marbles) }{9~ total ~marbles.}\\\frac{6}{9}[/tex]
