Before a chemist can combine a solution with other liquids in a laboratory, the temperature of the solution must be between 39⁰ C and 52⁰C. The chemist places the solution in a warmer that raises the temperature 6.5⁰C per hour. If the temperature is originally 0⁰C, how long will it take to raise the temperature to the necessary range values

Answer:

Hey there!

[tex]Answer:\boxed{20n+18}[/tex]

[tex]Explanation:[/tex]

[tex]10+2(10n+4)[/tex]

Let's start by distributing.

[tex]10+(2)(10n)+(2)(4)\\10+20n+8[/tex]

Now combine like terms.

[tex]10+20n+8\\(20n)+(10+8)\\20n+18[/tex]

Answer:

length = 12

width = 9

Step-by-step explanation:

We can use a system of linear equations to solve this problem. Lets make the variable L represent length and W represent width.

So we know that the length is 3 more than the width. An equation for this would be:

W = L - 3

We also know that the perimeter is 42 inches. The perimeter of a rectangle, using the variables L and W, is 2L + 2W, or 2(L + W). Using this, we can make the equation:

2(L + W) = 42

We can simplify the last equation by dividing both sides by 2:

L + W = 21

So now we have the two equations:

W = L - 3

L + W = 21

From here, there are multiple ways this question can be solved. I am going to use the substitution method here.

Knowing that W = L - 3, we can replace W in the second equation with L - 3.

L + L - 3 = 21

Add 3 to both sides.

2L = 24

Divide both sides by 2.

L = 12

Now we know that L = 12. Using this, we can replace L with 12 in the first equation to solve for W.

W = 12 - 3

W = 9

So:

L = length = 12

W = width = 9

I hope you find my answer helpful.

Answer:

2 1/9 or 19/9 depends on what answer is required/you want to use

Step-by-step explanation:

First, common denominator

Big cookie = 15/18 oz

Small cookie = 8/18 oz

15*2=30

30+8=38

38/18 = total weight of 2 large and 1 small

2 2/18 mixed fraction

2 1/9 Simplest answer

The total weight of 2 large cookies and small cookie is 2 1/9 oz

Given:

Weight of each large cookie = 5/6 oz

Weight of each small cookie = 4/9 oz

Total weight of 2 large cookies and small cookie = 2(Weight of each large cookie) + Weight of each small cookie

= 2(5/6) + 4/9

= 10/6 + 4/9

= (30+8) / 18

= 38/18

= 2 2/18

= 2 1/9 oz

Therefore, the weight of 2 large cookies and small cookie is 2 1/9 oz

You can write mn as m*n

=================================

Explanation:

The sum is the result of adding two or more numbers. Saying the sum of m and n means m+n.

Then we subtract off the product of m and n. The product is the result of multiplying m and n. We say m*n or mn to indicate their product.

Overall, we end up with m+n-mn

Answer:

2x-y+2= 0

Step-by-step explanation:

(-5,-2)=(x1, y1)

(3, 14) =(x2, y2)

now,

slope(m)= y2-y1 / x2-x1

=14+2 / 3+5

= 16 /8

=2 units

passing point = (-5,-2) = x1,y1

now,

eqn of the line can be represented as,

y -y1 = m (x-x1)

y +2 = 2 (x +5)

y+2 = 2x +10

y = 2x+10-8

0 = 2x+2-y

2x-y+2 =0 is the required eqn
