2. (a+b)²=a²+2ab+b²
(5x-2)²=(5x)²-2×5x×2+2²
(5x-2)²=25x²-20x+4

4. (a+b)²=a²+2ab+b²
(2x+5)²=(2x)²+2×2x×5+5²
(2x+5)²=4x²+20x+25
∵a=4, b=20, c=25
∴a+b+c=4+20+25=49

What is the volume to the nearest tenth of cubic inch.
oee [108]

Answer:

180.6 cubic inches. (Nearest tenth is the same as 1 decimal place)

Step-by-step explanation:

The volume of a cylinder formula is:

V

=

π

r

2

h

The diameter is

10

inches, well half of the diameter is

5

inches which is the radius. Radius is half of the diameter.

If you want the diameter back, just double it.

5

+

5

=

10

.

So we can now plug the numbers into the formula.

V

=

π

(

5

2

)

(

2.3

)

V

=

π

(

25

)

(

2.3

)

(5 Squared =25)

V

=

57.5

π

But if you didn't want it in terms of

π

, so you multiply:

57.5

×

3.14

=180.55

but rounding that to the nearest tenth is the same as rounding to

1 decimal place so you get

180.6 cubic inches.

Sally wants to buy an assortment of candy. She has $7 dollars she can spend in the candy store. The candy store sells chocolate
Tom [10]

Answer:

I found the table by an online search (it is below)

Sally has $7 to spend in candy.

The price of a chocolate bar is $1.50

The price of a lollipop is $0.75

The price of gumballs is $0.25

In the table, we have the following combinations.

a) 3 chocolate bars, 3 lollipops and 4 gumballs, the price is:

3*$1.50 + 3*$0.75 + 4*$0.25 = $7.75 (she can not buy this)

b) 3 chocolate bars and 4 gumballs, the price is:

3*$1.50 + 4*$0.25 = $5.50 (she can buy this)

c) 1 chocolate bar, 5 lollipops and 2 gumballs, the price is:

1*$1.50 + 5*$0.75 + 2*$0.25 =  $5.75 (she can buy this)

d) 2 chocolate bars, 2 lollipops and 8 gumballs, the price is:

2*$1.50 + 2*$0.75 + 8*$0.25 = $6.50 (she can buy this)
