45/200 x + x = 3920 what does x equal?

Mathematics
2 answers:
Alborosie3 years ago

Is that (x) times x + x ?

If so, x = 3,200

45/200 (x) x+x =3920

45 divided by 200 times x (3,200) plus x(3,200) equals 3920.

I hoped that helped !

A scientist measure change in the temperature of chemical solution at the start of the experiment , the solutions is at temperat
zhannawk [14.2K]

Answer:

The temperature of the chemical solution after t hours is -14.96-2.9t\;^{\circ}C

Step-by-step explanation:

Given that the initial temperature of the chemical solution, T_0= -14.96^{\circ}C.

The rate of decreasing temperature, R = 2.9^{\circ}C/ hour

So, after t hours, the temperature of the chemical solution will decrease by Rt=2.9t^{\circ}C.

So, the temperature of the chemical solution after t hours,

T=T_0-Rt \\\\\Rightarrow T = -14.96-2.9t\;^{\circ}C

Hence, the temperature of the chemical solution after t hours is -14.96-2.9t^{\circ}C.

Need to find the missing length and round to nearest tenth. I'm a bit confused.
astraxan [27]

ANSWER

15.9

EXPLANATION

Given:

A right-triangle with two sides and an angle

Desired Outcome:

The value of x

Apply the SOH CAH TOA rule

\begin{gathered} tan\theta=\frac{x}{34} \\ x=34\times0.4663 \\ x=15.8544 \end{gathered}

Hence, the value of x is 15.9 (rounded to the nearest tenth).

Alright, second try. 15 Points to whoever can solve with a half-decent explanation.
sesenic [268]

Answer:

29 cans

Step-by-step explanation:

To solve this problem we must use Heron's formula; A = \sqrt{S(S-a)(S-b)(S-c)}

S = 1/2 the perimeter of the given triangle

a, b, c = the measurements of the three given sides

The first step to solving this question is first finding the perimeter.

P = 65m + 74m + 67m

P = 206m

Now that we have our perimeter, we must divide P by 2 to get S.

S = 206/2

S = 103

Now we plug our numbers into Heron's formula.

A = \sqrt{S(S-a)(S-b)(S-c)}

A = \sqrt{103(103-65)(103-67)(103-74)}

A = \sqrt{103(38)(36)(29)}

A = \sqrt{103(39672)}

A = \sqrt{4086216}

Find the square root of this number.

A ≈ 2021.43909134... m²

If a can of paint covers 70 square meters, then you will need to figure out how many cans you need. This can be done by dividing the overall area of the triangle by the area that a single can of paint can cover.

\frac{2021.43909134...}{70} = 28.8777013049...

We know we can't buy 28.87... of a can (people simply do not sell parts of cans or half-full containers... unless its a bag of lays chips and their 80% air nonsense...) so we must round up to the nearest whole number.

28.87... = 29

Thus we finally have our answer: 29 cans of paint!
