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

Let n represent the time in hours for the service call and C represents the total cost in dollars. Write an equation that relates C and n
Answer:
C(n) = pn
Step-by-step explanation:
Given :
n = time in hours for service call
C = total cost
Total cost = unit cost per hour * time in hours
If unit cost per hour = p
Hence,
C(n) = p * n
C(n) = pn

4 units west and 1 unit south. How many units apart are
the students?
Answer:
(7,5) (4,1)= (3,4) might be it Im not really sure
Answer:
[tex] \sqrt{137} [/tex]
Step-by-step explanation:
Student A is at point (7, -5). Student B is at point (-4, -1).
We can find the distance between the two points using the distance formula.
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] d = \sqrt{(-4 - 7)^2 + (-1 - (-5))^2} [/tex]
[tex] d = \sqrt{(-11)^2 + (4)^2} [/tex]
[tex] d = \sqrt{121 + 16} [/tex]
[tex] d = \sqrt{137} [/tex]

opposite / hypotenuse
9/15 = 3/5
Answer:
a
Step-by-step explanation:
Sine is equal to the opposite divided by the hypotenuse
the opposite of E is 9 and the hypotenuse is 15
sin E = 9/15
we can simplify 9/15
9/3=3
15/3=5
the answer would be 3/5

Answer:
for #1: the new price is $37.80 and the amount discounted was $7.20
Step-by-step explanation:
convert 16% to a decimal and multiply to find how much discounted then subtract that from the initial value
0.16*45= 7.20
45-7.20= 37.80
did u need the others too?
Answer:
$7.20
$0.636
$27.50
$53.3333333333
Step-by-step explanation:
16% × $45 = $7.20
8% × $7.95 = $0.636
$5.50 = 20%
20% × 5 = 100%
$5.50 × 5 = $27.50
$16 = 30%
30% × 3 and 1/3 = 100%
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%.

5) A savings account earns 4.5% annual simple interest. The principle is
$1300. What is the balance after 3 years? *
Answer:
$1483.52
Step-by-step explanation:
P=principle
Fn=total at the end of a given year(=n) (subscript)
I= interest in decimal
F=P(1+I)
at end of first year F1=P(1+I)
at end of second year F=F1(1+I)= P(1+I)(1+I)= P(1+I)^2
or in general Fn=P(1+I)^n
The total amount kate had left is 4.20$ 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

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

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
