Four light bulbs cost $3.20.how much does it cost to buy 14 light bulbs ?

Answers

3.20 ÷ 4 = .80

SO

1 bulb costs $.80.

14 × .80 = 11.2 or 11.20 (its the same thing)

SO 14 light Bulbs cost $11.2 or $11.20.

Hope I helped ya!!

3.20= 4 light bulbs
3.20/4= .80cent per light bulb
.80*14=$11.20

A ladder of length 2x+1 feet is positioned against a wall such that bottom is x-1 feet away from a wall. The distance between the floor and top of the ladder is 2x. Assume that a right angle is formed by wall and the floor.

Answers

so leangh of ladder=2x+1

bottom edgre=x-1
wall edge=2x

so therefor, since this is a right triangle, use pythagorean theorem
a^2+b^2=c^2
c=hypotonues=longest side
b and a=sides touching the right angle

so x-1 and 2x are a and b
2x+1=c

subsitute
(x-1)^2+(2x)^2=(2x+1)^2
x^2-2x+1+4x^2=4x^2+4x+1
add like terms
5x^2-2x+1=4x^2+4x+1
subtract 1 from both sdies
5x^2-2x=4x^2+4x
subtract 4x from both sdies
5x^2-6x=4x^2
subtract 4x^2 from both sides
x^2-6x =0
factor out the x using distributive property which is
ab+ac=a(b+c)
x^2-6x=x(x-6)
(x)(x-6)=0

if xy=0 then assume x and/or y=0
x=0
we remember that one of the side legnths is 2x and if x=0 then the side legnth=0 which is not possible, so we discard

x-6=0
add 6 to both sides
x=6

subsitute and solve

legnth of ladder=2x+1
x=6 subsitute
2(6)+1=12+1=13
legnth of ladder =13 feet

height=2x
2(6)=12
height=12 feet

base=x-1
6-1=5

legnth of ladder=13 feet
height=12 feet
base=5 feet

pythagorean theorem
c^2 = a^2 + b^2

c = 2x+1
a = 2x
b = x-1

plug in and get:
(2x+1)^2 = (2x)^2 + (x-1)^2
4x^2 + 4x + 1 = 4x^2 + x^2 - 2x + 1 [distributed]
4x^2 + 4x + 1 = 5x^2 - 2x + 1 [added like terms]
x^2 - 6x = 0 [subtracted 4x^2 and 4x and 1]
x(x-6)=0 [factored out x]
x can equal 0 or 6

0 would not make any sense physically
therefore x = 6
plug this back into the length of the ladder 2x+1
2(6)+1 = 12 + 1 = 13

therefore the ladder is 13 feet long

Three pirates named Ahab, Sparrow, and Davy play a game. The pirates have a total of 210 coins, and each pirate has a different number of coins. At the end of the game, Ahab has won 5 coins and Davy has won 7 coins. Now, the ratio of coins belonging to Ahab, Sparrow, and Davy is 4:5:6, respectively. How many coins did Sparrow have at the beginning of the game?

Answers

Sparrow has 92 coins, in the starting.

What is ratio?

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Total number of coins in game = 210.

And the ratio of coins belongs to Ahab, Sparrow and Davy = 4 : 5 : 6

Let the multiplying factor in ration is x

The number of coins to Ahab = 4x

Number of coins belongs to Sparrow = 5x

And number of coins belong to Davy = 6x

Since, total number of coins = 210

4x + 5x + 6x = 210

15x = 210

x = 16

Number of coins that Sparrow has = 5 x = 5 (16) = 80

At the end Ahab and Davy wins 5 and 7 coins respectively

So at the starting coins that Sparrow has = 80 + 7 + 5 = 92

The required coins that Sparrow has at the beginning is 92.

Step-by-step explanation:

at the end of game, sparrow has $(5)/(4+5+6) * 210=70$ coins. since he loss 5+7=12 coins, then at the beginning he has 70+12=82 coins
