1.- In this problem we have to find the area of the circle. We know that the formula to find the area of a circle is:
A= πr<span>² 
</span>Meaning area of the circle= 3.14*radius<span>² 
Since the radius is equivalent to half the diameter, and we know the diameter is 40, the radius is 40/2 or 20ft
Which means the area of this circle is equal to
3.14*20</span><span>²
Which is equal to 1256

2.- Here we need to find the radius
And since the diameter of the tablecloth is equal to 42+8, to find it we just need to divide 50 by 2 which gives us 25
50/2= 25

3.- This question asks for the area to obtain it we use the formula:
</span>A= πr² 
So...
Area= 3.14*25² 
Which is equal to 1962.5


ANSWERS:
1.- 1256 in² (option 2)
2.- 25''  (option 3)
3.- 1962.5 in² (option 3)

I=prt,for p please show step by step for this variable
Bond [772]

Answer:

p = \dfrac{I}{rt}

Step-by-step explanation:

I = prt

Switch sides.

prt = I

We are solving for p. We want p alone on the left side. p is being multiplied by r and t, so we divide both sides by r and t.

\dfrac{prt}{rt} = \dfrac{I}{rt}

p = \dfrac{I}{rt}

What is the seventh term of the sequence whose nth term is (n + 1)(n − 2)?
pav-90 [236]
If you plug in 7 for n, you get
(7+1)(7-2).
Simplify that.
(8)(5)
Simplify that and you get the 7th term of the particular sequence is,

Mrs. Jones bought 6 kilograms of rice. After filling 10 containers with the same
9966 [12]

There are 514 gram rice in each container.

Step-by-step explanation:

Given,

Amount of rice = 6 kg

1 kg = 1000 g

6 kg = 6*1000 = 6000 g

Number of containers  = 10

Rice left = 860 g

Let,

x be the amount in each container.

Total amount of rice - Number of containers*Amount in each container = Amount of rice left

6000-10x=860\\6000-860=10x\\5140=10x\\10x=5140

Dividing both sides by 10

\frac{10x}{10}=\frac{5140}{10}\\x=514

There are 514 gram rice in each container.
