Answer:

Please check the explanation.

Step-by-step explanation:

As there are 1000000 units in 1 million

i.e.

1 million = 1000000 units

A house as purchases for $6780000.

Thus, the purchase price in million will be:

6780000/1000000 = 6.78 million

purchase price in millions nearest to an integer

As the number we are rounding is followed by 7, so will be round the number up.

Therefore,

$6780000 rounded to the nearest million = $7,000,000

What is the square root of 5x^2 = 300

vesna_86 [32]

So, values of x are: $x=2\sqrt{15},\,\,x=-2\sqrt{15}$

Step-by-step explanation:

We need to find the square root of 5x^2 = 300

Writing in mathematical form:

$5x^2=300$

Divide both sides by 5

$\frac{5x^2}{5}=\frac{300}{5}$

$x^2=60$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{60}$

$x=\pm (\sqrt{2\times 2\times 3\times 5})$

$x=\pm (\sqrt{2^2 \times 3\times 5})$

$x=\pm (2\sqrt{3\times 5})$

$x=\pm (2\sqrt{15})$

$x=2\sqrt{15},\,\,x=-2\sqrt{15}$

So, values of x are: $x=2\sqrt{15},\,\,x=-2\sqrt{15}$

Algebra 1 Assignment! Help needed as soon as possible! thanks so much to whoever helps! have a nice day

mezya [45]

Answer:

Step-by-step explanation:

go-kart = Gk

Head sock = Hs (what? a sock in the head? :/ what ?? )

Laser tag = Lt

Eq 1 ) Gk + Hs + Lt = 33

Eq 2) 2Gk + Hs + 0Lt = 48

Eq 3) 2Gk + Hs + 2Lt =64

This is a system of equations w/ 3 unknowns and 3 equations so we can solve this. :)

subtract Eq 2 from Eq 3

2Gk +Hs +2Lt =64

-(2Gk +Hs +0Lt =48)

0Gk + 0 Hs +2Lt = 16

Lt =8

so one Laser tag game is 8 dollars.. good... now use 8 in Eq. 1 and 3 for Lt price

Eq 1a) Gk + Hs +8 =33 simplify

Eq 1b) Gk + Hs = 25

Eq 3a) 2Gk +Hs +2(8) = 64 simplify

Eq3b) 2Gk + Hs =48

subtract Eq 1b from Eq 3b

2Gk + Hs =48

-(Gk + Hs =25)

Gk = 23

so one Gk ride costs 23 dollars and plug this into Eq 1

23 + Hs + 8 = 33

Hs = 2

Question 1 ) Gk = 23 Hs = 2 Lt = 8

solve new systems, same as above but with the new prices

Eq 1r ) Gk + Hs + Lt = 18

Eq 2r) 2Gk + Hs + 0Lt = 29

Eq 3r) 2Gk + Hs + 2Lt =35

subtracting 2r from 3r we get 2Lt = 6 then Lt =3 for the new price

plug that into 1r and 3r

Eq 1br) Gk + Hs = 15

Eq 3br) 2Gk +Hs = 29

subtract 1br from 3br

Gk = 14

plug this into 1r

Hs =1

Question 2 ) Gk=14 Hs =1 Lt=3

Question 3) wants 2 Hs and 2 Lt

w/o coupon the activities cost 2 ( 2+8) = 20 dollars

but there is no coupon for 2 of each game

so no, don't buy a coupon.. just play at full price

Hustler side note.. buy two of the 18 coupons and sell the 2 Gk rides to your teacher for 15 dollars each, still a good deal to guarantee a good grade on your Home Work .. (30 total)...... and get your games for just 6 dollars... excellent deal for you :)
