The ratio of the radii of two circles is 9:16. Then what is the ratio of their circumferences?

Answers

56.52:100.48

circumference is the diameter × π
diameter is radius × 2

first circle ->

r = 9
d = 9 × 2 = 18
c = 18 × π ≈ 56.52

second circle ->

r = 16
d = 16 × 2 = 32
c =  32 × π ≈ 100.48


so the ratio of circurfremce for 2 circles that have a ratio of radii 9:16 would be 56.52:100.48

The measurement of a rectangular dam are:length =60-2x width=2x depth=x/2 determine the volume of the damin terms of x

Answers

Volume of this rectangular dam=lenght  x width x depth
Data:
lenght=60-2x
width=2x
depth=x/2

V(x)=(60-2x)(2x)(x/2)
v(x)=(120x²-4x³)/2
v(x)=60x²-2x³

The volume of the rectangular dam is V(x)=60x²-2x³

If your state has a property tax rate of 0.056, and you pay $3,164.45 in property taxes every year, what is the assessed value of your property?a. $177,209
b. $21,265
c. $56,508
d. $48,684

Answers

The assessed value of your property is $56,508.

Given that, the rate of property tax=0.056 and tax money=$3,164.45.

What is a tax?

Money that the government collects is based on income, sales, and other activities.

Let the assessed value of your property is x.

Now, 0.056×x=3,164.45

⇒x=3,164.45/0.056

⇒x=56,508.035≈56,508

Therefore, the assessed value of your property is $56,508.

Henry wrote 4z² - z² as 4. Are 4z² - z² and 4 equivalent expressions?

Answers

No, a lone variable has an invisible one in front of it, So 4z (can’t put the top number sorry) So 4z - z would equal 3z

Final answer:

No, 4z² - z² and 4 are not equivalent expressions as 4z² - z² simplifies to 3z², not 4.

Explanation:

No, 4z² - z² and 4 are not equivalent expressions. To determine if two expressions are equivalent, we need to simplify both sides of the equation. In this case, 4z² - z² simplifies to 3z², not 4. Therefore, 4z² - z² and 4 are not equivalent expressions.
