Answer:
12566.4 mm²
Step-by-step explanation:
The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.
TSA = Total Surface Area
CSA = Curved Surface Area
TSA of open cylinder = CSA of cylinder + area of base or top
= 2πrh + πr²
= πr(2h + r)
From the above question:
r = 50mm
h = 15mm
Hence,
= π × 50 (2 × 15 + 50)
= π × 50 (30 + 50)
= π × 50(80)
= π × 4000
= 12566.370614mm²
Approximately = 12566.4 mm²
The Surface Area of the petri dish with no lid = 12566.4 mm²
what is the quotient of 30 and the sum of 5 and 7.
Answer:
2 1/2
Step-by-step explanation:
30/ (5+7)
solve using system of operations
PEMDAS
Parenthesis
Exponent
Multiplication/Division
Addition/Subtraction
30/(5+7)
parenthesis first so
5+7 = 12
30/12
then division
30/12= 2 6/12
6/12 can be simplified by 6 so
6/6 = 1 and 12/6 = 2
So your answer would be 2 1/2
The quotient of 30 and the sum of 5 and 7 is 2.5
Expressions and equationsFrom the question we are to write the information as an expression:
The sum of 5 and 7 is given as 5+7 = 12The quotient of 30 and the sum of 5 and 7 is expressed as [tex]\frac{30}{5+7}[/tex]Simplify the result
[tex]\frac{30}{5+7} =\frac{30}{12} = 2.5[/tex]

The quotient of a number and 7 decreased by 5 is 10. Write an equation and solve it to find the missing number.
Answer:
x = 105
Step-by-step explanation:
Let the unknown (missing) number be x.
In Mathematics, quotient simply means division i.e to divide a number by another.
Thus, translating the word problem into an algebraic expression, we have;
[tex] \frac{x}{7} - 5 = 10 [/tex]
To find the value of x, we would simplify the algebraic expression.
[tex] \frac{x}{7} = 10 + 5 [/tex]
[tex] \frac{x}{7} = 15 [/tex]
Cross-multiplying, we have;
[tex] x = 15 * 7 [/tex]
x = 105

FalseOut of 160 workers surveyed at a company, 37 walk to work.
a. What is the experimental probability that a randomly selected worker at that company walks to work?
b. Predict about how many of the 3300 workers at the company walk to work.
Answer:
Step-by-step explanation:
i got it wrong and it showed this instead
a-0.23125
b-720
The required,
(a) The experimental probability that a randomly selected worker at that company walks to work is approximately 0.23125 or 23.125%.
(b) we can predict that about 762 of the 3300 workers at the company walk to work.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
a. The experimental probability of a randomly selected worker at that company walking to work can be calculated as the ratio of the number of workers who walk to work to the total number of workers surveyed:
Experimental probability = Number of workers who walk to work / Total number of workers surveyed
Experimental probability = 37 / 160
Experimental probability = 0.23125 or 23.125%
Therefore, the experimental probability that a randomly selected worker at that company walks to work is approximately 0.23125 or 23.125%.
b. To predict about how many of the 3300 workers at the company walk to work, we can use the experimental probability calculated above to estimate the number of workers who walk to work out of the total number of workers:
Number of workers who walk to work = Experimental probability x Total number of workers
Number of workers who walk to work = 0.23125 x 3300
Number of workers who walk to work = 762.375
Therefore, we can predict that about 762 of the 3300 workers at the company walk to work.

Matt wants to hire a company to detail his car. Company A charges $15+17h where h represents the hours it takes to detail the car. Company B charges $20h where h represents the hours it takes to detail the car. For what number of hours is the total amount charged for detailing the car the same for both companies?
Answer:
5 hours
Step-by-step explanation:
First, you set the equations equal, so 20h=17h+15
Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15
Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.
Answer:
5 hours

What is the slope ( in simplest form) of the line through the points (-4,2) and (-16,-6)?
Answer:
2/3
Step-by-step explanation:
Slope = [tex]\frac{y2-y1}{x2-x1}[/tex]
(-4,2) = (x1,y1)
(-16,-6) = (x2,y2)
Slope = [tex]\frac{-6-2}{-16+4}[/tex]
= [tex]\frac{-8}{-12}[/tex]

Answer:
66m
Step-by-step explanation:
9+3+16+3+5+12+10+s
the s would 8 because
12+5 is 17
17-9 would be 8 so we would add 8.
9+3+16+3+5+12+10+8
Answer:
66 m
Step-by-step explanation:
We know that Perimeter is sum of all the sides of any triangle / quadrilateral / polygon . Here we see that that the side lenght are ,
8cm , 10cm , 12cm , 3m , 5m , 16m ,9m , 3cm .
On adding these , we will get Perimeter .
⇒ P = 8cm + 10cm + 12cm + 3m + 5m + 16m + 9m + 3m
⇒ P = 66m
Hence the required answer is 66mWhat is 0.14 4 recurring as a fraction
Answer:
0.1414... in a fraction is 14/99
Step-by-step explanation:
Given the number 0.1414...
we have to represent the above in terms of fraction
Let x=0.1414.... → (1)
Multiplying by 100 on both sides
100x=14.1414.... → (2)
Subtract (1) from (2), we get
99x=14
x=14/99
hence, 0.1414... in a fraction is 14/99

Find the volume of the figure. Round to the nearest tenth if necessary.
1 point
3.4 in
4.8 in
25
Answer: 34 in^3
Step-by-step explanation:
Surface area of triangle = 1/2 x 3.4 x 2.5 = 4.25
To find the volume of the prism, multiply the surface area of the triangle by length.
So 4.25 x 8 = 34 in^3
Write the repeating decimal as a mixed number.
Answer:
1 1/30
Explanation:
we know that 0.3 (recurring) is equivalent to ⅓. thus, we can find 0.03 (recurring) by adding an extra decimal behind the denominator to get 1/30.
accounting for the 1, we can now get 1 1/30.
