Answer:
at first : circumference = 25.12 = pi*d--------> d= 25.12/ pi
after one minute: circumference = 75.63= pi*d-------> d= 75.63/pi
Step-by-step explanation:
A) minute 1) diameter = 7.995946004446154 mm
minute 2) diameter = 24.07378170048816 mm
(I'll assume that you can round if necessary)
B) The diameter of the new ink spot is roughly 3X larger
(technically 3.01074841 X larger)

How much is 11 5 cents equal?
how much is 7 one dimes equal?
Answer:
11 x 5 cents is 55 cents
55 cents is equal to:
0.55 dollars
5.5 dimes
or 11 nickles
1 dime = 10 cents.
Since you have 7, you have a total of 70 cents.
70 cents is equal to:
0.7 dollars
or 14 nickles
In total you have:
1.25 dollars or
1 dollar and 25 cents.

Answer:
I hope this is what it's asking
Step-by-step explanation:
the advantage would be that basically you don't have to do any real number calculations, you just take all of the steps and put it into one, so if u had real numbers you could just plug them in with the equation

Which of the following would be considered as an event (left spinner, right spinner) that's a member of the sample space for Trevor's spins.
options:
(2, 2)
(3, 4)
(7, 1)
(2, 5)
Answer the question below
Simple interest formula:
Total = start value x (1 + rate x time)
Total = 600 x (1 + 0.12 x 6)
Total = $643.20
answer: B. $643.20
The voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27/125 of a volt and it has been reduced three times. Write the voltage in exponential form, what was the original voltage in the circuit?
I belive this is the answer
x³ = 27/125; and
x = 3/5.
explanation:
Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us
x³.
The current voltage is 27/125; this gives us the equation
x³ = 27/125.
To solve this, take the cubed root of both sides:
∛(x³) = ∛(27/125)
x = (∛27)/(∛125)
x = (∛(3*3*3))/(∛(5*5*5))
x = 3/5
A kilometer is about 0.62 miles. Which student provides the best estimate to convert 3 kilometers to miles?
Goscia. 0.62 is about 0.60. 3 times 0.60 equals 1.80. Imani. 0.62 is about 0.60. 3 plus 0.60 equals 3.60. Rowan. 3 kilometers is close to 10 kilometers. 10 times 0.62 equals 6.20. Therese. 3 kilometers is close to 10 kilometers. 10 plus 0.62 equals 10.62.
Goscia
Imani
Rowan
Therese
Answer:
Goscia
Step-by-step explanation:
The most accurate one is Goscia, it's closest to the answer.
Assume one kilometer is equal to x and 0.62:
x = 0.62
3 kilometers would be equal to what? Well, 3 * 1 kilometers or 3 * x = 3.0.62 = 1.86. The closest answer to this is Goscia's.

Answer:
your answer is 12 inches hon!
Step-by-step explanation:
if we divide 864 by 6 we get 144 and the square root of 144 is 12!
Answer:
12
Step-by-step explanation:
volume of a cube = 6 × (length of edge)^2
let the length = X
hence,
6X^2 = 864
X = 12
Ms. Johnson adds 2 cubes of suger to a 6 ounce cup of tea. Ms. Huáng adds 3 cubes of sugar to a 9 ounce cup of tea. which statement is true?
. Diego received and spent money in the following ways last week.
For each example, write a positive or negative number to represent the change in money from his perspective.
i. He earned $30 dollars by cutting the neighbor’s lawn.
a
ii. He spent $14 going to the movies.
a
iii. He spent $3.55 on an ice cream cone.
a
b. What does 0 mean in this situation?
Type your response in the space below.
Answer:
earned $30 means +30
spent $14 means -14 (he used the money to buy something meaning he loses some money)
spent $3.55 means -3.55 (again, he uses some money to buy something which means he loses this amount of money)
In this situation 0 means he either didnt gain/earn money or he spent all his money.

Part D
Wendell plans to paint the doghouse after it’s built. He wants to know what the surface area of the outside of the doghouse will be. To find the surface area, first break up any composite shapes into rectangles and triangles. Which shape is considered a composite shape? When the shape is decomposed, what are the dimensions of the resulting shapes necessary for finding surface area?
Part E
Using the results from part D and the dimensions of the other surfaces, find the surface area of the outside of the doghouse. Be sure to include the bottom surface in your calculation.
The total surface area of doghouse is 5052 sq. inch and total volume of doghouse is 16200 cubic inch
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
In the given question, we have to find which shape is considered a composite shape and when the shape is decomposed, then the dimensions of the resulting shapes necessary for finding surface area.
The graph of the given question is:
The slice will be shaped in the manner shown by the red-lined pentagonal shape A. The slice will have the red-lined shape, which is a rectangle as indicated B.
The slice will have the red-lined shape, which is a rectangle as shown in C. Only the Pentagon, which is made up of a triangle and a rectangle as seen in D, is a composite shape in the image.
In the given shape the dimensions of triangle is 18 inch, 18 inch, 30 inch.
The dimensions of rectangle is 18 inch, 30 inch.
7 rectangles and 2 triangles are the total number of decomposed shapes.
Total Area of above rectangles = 36x18 + 36x18 + 36x18 + 36x18 + 30x36
Total Area of above rectangles = 2592 + 1080 sq. inch
Total Area of above rectangles = 3672 sq. inch
Area of decomposed rectangles = 30 x 18 +30x 18
Area of decomposed rectangles = 1080 sq. inch
Area of triangles = 0.5 x 10 x 30 + 0.5 x 10 x 30
Area of triangles = 300 sq. inch
Total surface area = 3672 + 1080 + 300
Total surface area = 5052 sq. inch
Total volume = Total volume of cuboid + Total volume of upper triangular region
Total volume of cuboid = 30 x 36 x 18
Total volume of cuboid = 10800 cubic inch
Total volume of upper triangular region = 0.5 x 30 x 10 x 36
Total volume of upper triangular region = 5400 cubic inch
Total volume = 10800 cubic inch + 5400 cubic inch
Total volume = 16200 cubic inch

Are they correct? Why or why not? answer correctly thank you 10 points.
Answer:
No.
Step-by-step explanation:
the system of equations provided in the condition consists of two linear equations in slope-interception form. The slope of the 1st equation is equal to the slope of 2d equation. It means, the lines are parallel. In other words, no solution of this system, they are not correct.
Answer: no.
What is 3.45 as a percent and a mixed number?
Answer:
the answer that 3.45 should be as a percent should be 345% because you mutliply 3.45 times 100 getting an answer of 345% and if you want to convert into a mixed number the percent 3 45/100 or simplified to 3 9/20 so hopefully that is the correct answer.

Answer:
The first one is 280 The second is all of the above
Step-by-step explanation:
2. You first divide the larger group by the smaller group to find the ratio
700 ÷ 40 = 17.5
Now you multiply the ammount of patients who responded with 8 when there were 40 asked, by the ammount you multiply 40 by to get to 700
16 × 17.5 = 280
The amount of people expected to respond with 8 hours when there is a sample size of 700 is 280 people.
3. All of these examples represent two sets of related data whose change is being compared over a set amount of time.
