Answer:

Let \ base = x\\5^2 = x^2 + 4^2\\25-16 = x^2\\9 = x^2\\x = 3\\\\\\opposite = 4\\adjacent = 3\\hypotenuse = 5\\Sin \theta = \frac{opposite}{hypotenuse} = \frac{4}{5}   \\\\Cos\theta = \frac{adjacent}{hypotenuse} =\frac{3}{5}\\\\Tan \theta = \frac{opposite}{adjacent} = \frac{4}{3}

(x+5)/4=1/2
first get rid of the fraction
multiply both sides by 4
x+5=2
subtract 5
x=-3

(2x+1)/(4x-1)=2/3
get rid of the fractions,
multiply both sdies by (4x-1)(3)
(2x+1)(3)=(2)(4x-1)
distribute
6x+3=8x-2
subtract 6x form both sdies
3=2x-2
add 2
5=2x
divide by 2
5/2=x

45 620 000 to the nearest million​
aniked [119]

Answer:

46,000,000 (46 million)

Step-by-step explanation:

If the number to the right (in this case the hundred thousands place) is 5 or greater then you round up.

If it was lower than 5 you would round down.

As the number in the hundred thousands place is 6, this means we can round up.

if the class charges $15 per ticket write an equation that could be used to determine the number of tickets the class would need
OverLord2011 [107]

t = number of tickets

15t ≥ 1500

so....

step 1. 15t ≥ 1500 --> divide both sides by 15 --> 15t/15 ≥ 1500/15

step 2. t ≥ 100


So 100 at the least, ticket should be sold to reach atleast $1500.


I hope this helps. :)

The difference between the coat cost for Delaware vs Fairfield is $0.60

For Delaware: 80 × .0725 = $5.80
80+5.80= $85.80

For Fairfield: 80 × .065 = $5.20
80+5.20=$85.20

85.80-85.20=0.60
