Answer:
Radius: about 1.42 mm
Step-by-step explanation:
First, you divide the circumference (8.9) by 3.14, or π.
Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)
Diameter (2.83439490446) divided by 2 = radius (1.41719745223)
Now, you have to round to the nearest hundredth.
1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.
Hope this helped :)!

Answers
Answer:
The answer is 76ft³
sorry for bad handwriting
The volume of the given figure is 76 feet³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a figure.
This can be divided in to two rectangular prisms.
One prism with length = 4 feet, width = 2 feet and height = 8 feet.
Other one with length = 6 - 4 = 2 feet, width = 2 feet and height = 3 feet.
Volume = length × width × height
Total volume of the figure = (4 × 2 × 8) + (2 × 2 × 3)
= 64 + 12
= 76 feet³
Hence the total volume of the figure is 76 feet³.

Answer:
a. the first and last one
b. the second and third one
Step-by-step explanation:
a. 11x-3x-10x=18x, so the first one is definitely the answer. If you look at the last one, you can see that 10x+8x also equals 18x. The other options do not equal 18x, so those can be eliminated.
b. If you distribute the 3 outside of the parentheses, you can see that the expression 3(1+3y) equals 3+9y (because 3*1=3 and 3*3y=9y). So, the third one can be determined to be one of the answers. We can see that the second one also simplifies to be 3+9y, so this one can also be determined to be the answer. The other ones can be eliminated because they do not equal 3+9y.
Hope this helped! :)

a. the mass of a empty basket is ___
b. explain your answer (in short)
please help
Answers
Answer:
mass of empty basket: 1.21 kg
Explanation:
the mass of basket is constant. Let the mass of basket be "b" and mass of each balls be "m"
Make equations:
b + 3(m) = 3.64 ___ equation 1b + 5(m) = 5.26 ___ equation 2solve them simultaneously,
3.64 - 3(m) = 5.26 - 5(m)-3(m) + 5(m) = 5.26 - 3.642(m) = 1.62m = 0.81 kgmass of basket,
b = 3.64 - 3(m)3.64 - 3(0.81 )1.21 kgNow
x+3y=3.64=>x=3.64-3y--(1)x+5y=5.26=>x=5.26-5ySo
3.64-3y=5.26-5y-3y+5y=5.26-3.642y=1.62y=0.81kgSo

A school fundraiser has a minimum target of $600. Faculty donated $200 and there are 10 student clubs that are participating with different activities. Write an inequality showing the amount money each club should raise to meet the minimum target. Use f for the amount of money that each club raises.
Answers
Answer:
600=10f+200
Step-by-step explanation:
since $600 is the target, and the faculty already donated 200 dollars 200 would be the y intercept. since f is the amount of money that the clubs should raise, we can set that as 10 f since there are 10 clubs and since it needs to be inequality, it would be written in the y = mx + b format. hope this helps!

Answer:
incorrect, correct answer is 4√2

When you remove the square root You will have to remove them completely. so that the inside of the square root cannot be removed any more numbers (I'm not good at English but I hope u understand what I want u to know :)))
√32 = √2×2×2×2×2
Match 2 identical numbers one at a time and bring them out. ;
√32 = 2×2√2
√32 = 4√2 correct answer!
find you If you want to check if your square root removal is correct or not. Multiply the answer you have given by itself, for example:
