Answer:

Step-by-step explanation:

The statements supported by graphs are,

A. The concentration of the chemical decreases as the reaction progresses over time.

E. The concentration of he reactant is 160 milligrams/liter at the start of the reaction.

C. The concentration of the chemical cannot exceed 50 milligrams/liter.

The function which represent time required for the concentration of a certain chemical to reach a value of n milligrams/liter during a reaction.

                   [tex]f(n) = log 0.98(n/50)[/tex]

From given graph, It is obseved that

Answer:

x = 59º

y = 40º

z = 59º

Step-by-step explanation:

x= 180 - 121 = 59º

59 + 40 + z = 180

       99 + z = 180

        z= 81º

y = 40º

x = 180 - (81 + 40)

x = 59

Answer:

640 metres

Step-by-step explanation:

Area of a rectangular field = 24000 square metres

Width of a rectangular field = 120 metre

Also,

Area of a rectangular field = Length × Breadth

24000 = Length × 120

Length = [tex]\frac{24000}{120}=200[/tex] metre

Length of wire required to fence the field = Perimeter of the rectangular field

= 2 (length + width)

= 2 (200 + 120)

= 2 (320)

= 640 metres

Answer:

5

Step-by-step explanation:

The consecutive primes starting from 2 are

2, 3, 5, 7, 11

Summing gives 2 + 3 + 5 + 7 + 11 = 28

and 28 is divisible by 7

Thus the required number of primes is 5

The fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.

To determine what is the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7, the following calculation must be performed:

Therefore, the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.

Step-by-step explanation:

So I here's my thought process on this:

200 divided by 2 is 100

100 - 40% is 60, leaving 40 behind.

So double that and it would be:

200 - 40% is 120

200 - 120 = 80

80% is the answer.

Answer:

Step-by-step explanation:

Since there are 16 oz in 1 lb, to find the amount in 3 lbs, you would just multiply it by 3

16 · 3 = 48

to find the price you divide the total price by number of oz.

6.95 ÷ 48 ≈ 0.1448

since money is measured in hundreths, you would round up (because thats how money works) so it would be roughly 15 cents. unless your teacher wants you to round down to 14 cents

Answer:

Number of bagels = 10

Number of donuts = 25

Step-by-step explanation:

Let Number of bagels = b

Number of donuts = d

As given,

Each donut cost $0.55 and each bagel cost $1.20

⇒ Cost of d donuts = $0.55d

   Cost of b bagels = $1.20b

Also given,

Jamian bought a total of 35 bagels and donuts

⇒ b + d = 35     ........(1)

Also,

He paid a total of  $25.75.

⇒ 1.20b + 0.55d = 25.75          .........(2)

Now,

Multiply equation (1) by 1.20 , we get

1.20( b + d = 35 )

⇒1.20b + 1.20d = 42               ..........(3)

Now,

Subtract equation (2) from equation (3), we get

1.20b + 1.20d  - ( 1.20b + 0.55d ) = 42 - 25.75

⇒1.20b + 1.20d  - 1.20b - 0.55d  = 16.25

⇒0.65d = 16.25

⇒d = [tex]\frac{16.25}{0.65}[/tex] = 25

⇒d = 25

Put the value of d in equation (1) , we get

b + d = 35

⇒b + 25 = 35

⇒b = 35 - 25 = 10

⇒b = 10

∴ we get

Number of bagels = b = 10

Number of donuts = d = 25

Answer:

Side A = 25 in

Side B = 14 in

Side C = 17 in

Step-by-step explanation:

Perimeter of a triangle = 56 in

Side B = x

Side A = 2x - 3

Side C = 1/2x + 10

Perimeter of a triangle = side A + Side B + side C

56 = (2x -3) + x + (1/2x + 10)

56 = 2x - 3 + x + 1/2x + 10

56 + 3 - 10 = 2x + x + 1/2x

49 = 3 1/2x

Note: 3 1/2x = 3.5x

49 = 3.5x

x = 49/3.5

x = 14 in

Side B = x = 14 in

Side A = 2x - 3

= 2(14) - 3

= 28 - 3

= 25 in

Side C = 1/2x + 10

= 1/2(14) + 10

= 7 + 10

= 17 in
