If the circumference of a circle is increased by 50%, then its area will be increased by (a) 100% (b) 125% (c) 150% (d) 75%

Svetradugi [14.3K]

Answer:

Hi, There!

Option B 125% Is the Most Accurate Answer

Step-by-step explanation:

Circumference is the distance around a plane shape. So, it also measures length.

Length and area of two similar shapes are related by the formula

$\frac{A_{1} }{A_{2} } =(_{} \frac{I_{1} }{I_{2\\ ^{~2~} }}$

Where the A in both cases represents area and the L represents length. But here the Ls will represent circumference.

Since the circumference of the circle increased by 50%, then the new circumference becomes

$l_{2} = l_{1} + 0.5l_{1} =1.5l_{1}$

Now subtracting from the original area then

$2.25 - 1=1.25$

This means that the area was increased by 1.25, which means 125%

Hence option B is the correct answer

A B C or D? Multiple choice please help

S_A_V [24]

Answer: a

Step-by-step explanation:

(6z³+3z²-4z+8) - (4z²-3z+2)

all of the numbers in the second set of parenthesis are going to have their signs switched so...

(6z³+3z²-4z+8) + (-4z²+3z-2)

now you add the two sets of parenthesis

6z³ - z² - z + 6

Yall how do I find a common denominator? If the question is 3/4+2/3 would I multiply 3 by 3 and 2 by 4?? So if 3x3 is 9 and 2x4

PolarNik [594]

the common denominator is the number on the bottom of the fraction. in this case it would be 4 (in 3/4) and 3 (in 2/3), you have to find a number which equals the same for both! so 3 and 4 both go into 12. 3 × 4 and 4 × 3, so you common denominator is 12! but, you also have to multiple the same number up on the top number. so 3 × 3 and 2 × 4. Then you Add! but only the top numbers! you can only add/subtract fractions that have the same common denominator! your answer will end up being the improper fraction of 17/12. if you have to turn it into a decimal or make it proper, then do so ^^

to find a common denominator, you have to find the number which both numbers equally go into! so no decimals. check the times tables!

The cost of a Whoppie Burger is $2.75 and a Whoppie Jr. Burger is $1.00. If 32 total burgers are ordered for a class, find the f

Viktor [21]

Answer:

c. C(x) = 88 - 1.75x

Step-by-step explanation:

Let's represent this with an equation. We know that the total number of burgers is 32, and the number of Whoppie Jr. is x, so the number of Whoppie is 32-x.

Each Whoppie costs 2.75, and each Whoppie Jr. costs 1, so multiply the cost by the number to get the equation:

C(x) = 1x + 2.75(32-x)

Now distribute and simplify.

C(x) = 2.75*32 + 1x -2.75x

C(x) = 88 -1.75x
