A square has a perimeter of 18cm. How long is the side of the square? 15 POINTS**

emmainna [20.7K]

Answer:

Each side is 4.5 cm

Step-by-step explanation:

$18 \div 4 = 4.5$

To find the perimeter of a square you add all the sides.

But to find the side length you do the opposite. Which is the equation above.

Hope this helps : )

Divide 7/24 by 35/48 and reduce the quotient to the lowest fraction

Ahat [919]

Well, an easier way than to divide fractions is to multiply the fractions, but to do that, flip the numerator and denominator for the second fraction.
For example, it becomes: 7 48 2
-------- × -------- = --------- (top×top & bottom×bottom)
24 35 5

Answer is: 2/5

Solve by unfolding: a0=2, and, n>=1, a_n=7a_n-1.

vodomira [7]

We are told that the first term is 2. The next term is 7(2) = 14; the third term is 7(14) = 98. And so on. So, the first term and the common ratio (7) are known.

The nth term of this geometric series is a_n = 2(7)^(n-1).

Check: What is the first term? We expect it is 2. 2(7)^(1-1) = 2(1) = 2. Correct.

What is the third term? We expect it is 98. 2(7)^(3-1) = 2(7)^2 = 98. Right.

Answer:

B.) 1/7

Step-by-step explanation:

you have a total of 15 the you subtract one so you have

15-1= 14

you had 3 dimes and you took one out so you have

3-1=2

so you have 2/14 and in simplest for that is 1/7 because you divide both by 2

I hope this was good enough:

An architect plans to buy 5 stone spheres and 3 stone cylinders. For the same amount, she can buy 2 stone spheres and 6 stone c

Vedmedyk [2.9K]

The cost of each stone sphere is $ 36.81

Solution:

Given that,

An architect plans to buy 5 stone spheres and 3 stone cylinders

For the same amount, she can buy 2 stone spheres and 6 stone cylinders

Let "x" be that same amount

Let "a" be the cost of each stone sphere

Cost of each stone cylinder = $ 36.81

Therefore,

x = 5 stone spheres and 3 stone cylinders

x = 5a + 3(36.81)

Similarly,

x = 2 stone spheres and 6 stone cylinders

x = 2a + 6(36.81)

Equate both,

$5a + 3(36.81) = 2a + 6(36.81)\\\\5a + 110.43 = 2a + 220.86\\\\5a - 2a = 220.86 - 110.43\\\\3a = 110.43\\\\a = 36.81$

Thus cost of each stone sphere is $ 36.81
