You are a laboratory technician. You are filling spherical flasks with a salt solution and then putting them into boxes. Each flask has a volume of 113.04 cubic inches.
Rounded to the nearest tenth of an inch, what is the radius of one flask?
3.0
3.6
5.2
6.4
6.9
Answer:
3.0 inches
Step-by-step explanation:
The formula for the volume of a sphere is
V = 4/3 × π × r³
V = 113.04 cubic inches
To find r
r = (3V/4π)⅓
r = (3 × 113.04/4 × π )⅓
r = 3.0 inches
The radius of one flask = 3.0 inches
Option A is correct
Two heads 35 Two tails 23 One head, One tail 52 What is the theoretical probability that a coin toss results in two heads showing?
Answer:
[tex]Pr = 0.25[/tex]
Step-by-step explanation:
Given
Two heads ---> 35
Two tails ---> 23
One head, One tail ---> 52
Required
The theoretical probability of 2 heads
When a coin is tossed, the probabilities are:
[tex]P(Head) = 0.5[/tex]
[tex]P(Tail) = 0.5[/tex]
So, the theoretical probability of 2 heads is:
[tex]Pr = P(Head) * P(Head)[/tex]
[tex]Pr = 0.5 *0.5[/tex]
[tex]Pr = 0.25[/tex]
Notice that the given parameters were not used. Using them will only give us the result of the experimental probabilities, because they are recorded from an experiment

Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca. Is he correct, if the sandwich sizes are different.
Answer:
Riley is correct
Step-by-step explanation:
Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca.
To find out the fraction of how much more Riley ate than Luca, we carry out Subtraction operation
= Fraction of what Riley ate - Fraction of what Luca ate
= 5/6 - 3/6
Lowe's Common Denominator = 6
= 5 - 3/6
= 2/6
Therefore, Riley is correct
The numbers 1 - 30 are written down on pieces of paper and placed in a hat for
students to to randomly select.
Answer:
Event A = 1/3
Event B = 1/6
Step-by-step explanation:
The probability of drawing a number between 1 and 10 (Event A) is approximately 0.3333 or 33.33%.
To calculate the probability of Event A, we need to determine the total number of favorable outcomes (numbers between 1 and 10) and divide it by the total number of possible outcomes (all numbers from 1 to 30).
Counting the favorable outcomes:
Event A consists of numbers between 1 and 10. So, there are 10 favorable outcomes: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
Counting the total possible outcomes:
The hat contains numbers from 1 to 30. So, there are 30 possible outcomes: {1, 2, 3, ..., 30}.
Calculating the probability of Event A (P(A)):
The probability of an event is given by the formula:
P(A) = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes).
In this case,
P(A) = 10 (favorable outcomes) / 30 (total possible outcomes)
P (A) = 1/3 ≈ 0.3333 or 33.33%.

Find the point P along the directed line segment from point A(–13, 6) to point B(2, 20) that divides the segment in the ratio 2 to 3.
Answer:
(-4, 14.4)
Step-by-step explanation:
The midpoint formula is expressed as;
M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}
Get X;
X = ax1+bx2/a+b
X = -13(2)+ 2(3)/2+3
X = -26+6/5
X = -20/5
X = -4
Get Y:
Y =ay1+by2/a+b
Y = 2(6)+3(20)/2+3
Y = 12+60/5
Y = 72/5
Y = 14.4
Hence the coordinate of point P dividing A and B in the ratio 2 to 3 is
(-4, 14.4)

The total amount kate had left is 4.20$ after buying 7 pencils at p cents. Please explain how do I answer this question and find the value of p
Answer:
each pencil almost costs 83 cents which is the value of p
Step-by-step explanation:
Here most important data that the amount which Kate had before the purchase of pencils is missing.
For our convenience i am assuming Kate had $10 before the purchase of pencil.
Since, after purchase the left with Kate = $4.20
Therefore, amount spend on purchase of pencils = $10-$4.20 = $5.80
In $5.80 Kate purchased 7 pencils
Therefore cost of each pencil p = 5.80/7 = $0.8285 ≅ $0.83
Therefore each pencil almost costs 83 cents which is the value of p
Ms. Peters has 36 red, blue, and green markers. She has an equal number of
each color of marker. She arranges the red markers in 2 equal groups. How
many red markers are in each group?
18
9
6
12
Answer:
6 markers
Step-by-step explanation:
1) Find the number of red markers
Firstly, we know that Ms. Peters has a total of 36 markers. There are 3 colours within these 36 markers. Because she has an equal number of each colour, divide 36 by 3 to find the number of red markers.
36÷3=12
Therefore, Ms. Peters has 12 red markers.
2) Find the number of red markers in each group
Ms. Peters then divides the red markers into 2 equal groups. Because we now know that there are 12 red markers, divide 12 by 2 to find this number.
12÷2=6
Therefore, there are 6 red markers in each group.

Answer:
28260 cubic cm
Step-by-step explanation:
Given,
Diameter of the cylinder = 30cm
So, radius of the cylinder = 30cm ÷2 = 15 cm
Height of the cylinder = 40 cm
There, volume of the cylinder,
[tex] = \pi {r}^{2} h[/tex]
[tex] = 3.14 \times 15cm \times 15cm \times 40cm[/tex]
[tex] = {28260cm}^{3} [/tex]
Answer:
diameter=30cm
radius=30/2=15
volume of cylinder = pi×r²×h
volume of cylinder=3.14×15²×40cm
volume of cylinder=28,260cm³

what is the slope of 2x-4y=5
Answer:
1/2 or .5
Step-by-step explanation:
Hey There!
So the first step of this problem is to get y on one side and everything else on the other side
to do so we use inverse operations
so to get rid of the 2x we subtract 2x from each side
we would end up with -4y=5-2x
now want to get rid of the -4 on the y
to do so we would divide each side by -4
we would end up with
[tex]y=\frac{1}{2}x -\frac{4}{5}[/tex]
so we can conclude that the slope is 1/2 or .5

Avah was reading a 675 page novel, at a rate of 35 pages per hour.
a. Write an equation to represent the number of pages left to read ,N, and the number of
hours,h, Avah has been reading.
Answer:
N = 675 - 35h
Step-by-step explanation:
She reads 35 pages per hour.
In 1 hour, she reads 35 * 1 pages.
In 2 hours, she reads 35 * 2 pages.
In h hours, she reads 35 * h, or 35h, pages.
The book has 675 pages. The number of pages left to read is the total number of pages minus the pages she already read.
The number of pages left to read is 675 - 35h.
Equation:
N = 675 - 35h

The price of televisions has dropped dramatically over the last three years. Three years ago a 32 inch television was $500. This year the tv was on sale for $199. What is the percent change?
A percentage is a way to describe a part of a whole. The percentage change in the price of the TV will be 60.2%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is mentioned that the price of the tv 3 years ago was $500, while the current price of the tv is $199. Therefore, the percentage change in the price of the tv can be written as,
[tex]\rm Percentage\ change = \dfrac{\text{Initial value - Final value}}{Initial\ value} \times 100\%[/tex]
[tex]\rm Percentage\ change = \dfrac{\$500-\$199}{\$500} \times 100= 60.2\%[/tex]
Hence, the percentage change in the price of the TV will be 60.2%.
