Find the 30th term.

18,22,26,30

Explanation:

+4 each time?

Answer:

Step-by-step explanation:

so 8^2 +10x+3 (if you times 8*3 -gives you 24)

the middle number is 10X right so then you have to guess two numbers that either add up or take away to make it a positive 10.

so example if i try 5+5 it gives me 10 but it i multiply 5 by 5 -it gives 25 therefore lets try another pair of numbers.

i chose 6 and 4 because when i add them it gives me 10 and when i multiply them, it gives me 24.

therefore im just going to:

8x^2+6x+4x+3

to factorise im going to use 2x

2x(4x+3) + 1(4x+3)

so my answer is (2x+1) and (4x+3)

Answer:

C is the answer.

Step-by-step explanation:

i just got it right so that means you would too> let's goooo!!

The employees will have to travel within 19.25 minutes to 28.75 minutes.

'Normal distribution is a continuous probability distribution wherein values lie in a symmetrical fashion mostly situated around the mean.'

According to the given problem,

Mean time = 24 minutes

Standard deviation = 5 minutes

Therefore,

⇒24 + 5 = 29

⇒24 - 5 = 19

Now,

(29 - 19) * 95% = 9.5

Hence, we can conclude that 95% of the employees will have to travel within 19.25 minutes to 28.75 minutes.

The coordinates of point D( 4,4)

Step-by-step explanation:

Step(i):-

Given points are E(10,4) and B(16,4)

'E' is the mid-point of segment BD

Let D(x₁, y₁) be a point

   E = midpoint of segment BD

 [tex](10,4) = (\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )[/tex]

[tex]10 = \frac{x_{1} +16 }{2}[/tex]    

20 = x₁ + 16

20-16 = x₁

  x₁ =4

Step(ii):-  

[tex]\frac{y_{1} +y_{2} }{2} = 4[/tex]

[tex]\frac{4 +y_{2} }{2} = 4[/tex]

4 + y₂ = 8

    y₂ = 8-4 =4

Answer:

66.9375

Step-by-step explanation:

from what you told me 4cm=21km

if you divide 21 by four, you get how many km is one cm. which is 5.25km

15 divided by 4 = 3.75

what we know is that 4 can go into 15 three whole times. so.. 21x3=63

now what we need to figure out is that .75

so, 75 is three quarters, so i divided 5.25 divided by 4 to get how much one quarter of a cm is in km. then i multipled that by three, giving me: 3.9375

63+3.9375= 66.9375

Step-by-step explanation:

side lengths with greatest area = x = 120/2 and y = 120/2

60 × 60 = 3600ft²

3600/600 = 6 horses

The required maximum number of horses is 7.

Given that,
Madison purchased 240 ft of fencing to build a corral for her horses. If each horse requires 600 ft2 of space, what is the maximum number of horses Madison can put in the corral she builds with the fencing is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Madison has 240 ft of fencing,
Circumference of  corral = 240 ft
2πr = 240
r = 38.2
Now the area of the circular corral,
= πr²
= 4584.33

Now, the number of horses,
= total area of corral/area for each horse
= 4584.33 / 600
= 7.64
≈ 7

Thus, the required maximum number of horses is 7.

1. I hypothesize that if you continue to add more drops, then the time it takes will continue to increase.

3. The formation continued to increased. As more was added, the time it took to reach the full reaction was increased.  

4. Yes.  

5. When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.

6. 6mL.

Step-by-step explanation:

like i said,, i go this correct so dw ! <3

The rate of reaction depends on the slow step of a reaction.

A hypothesis is a tentative explanation of an observation. This question refers to an experiment so I will try to explain as much as possible. We can see that the rate of reaction is determined by the concentration of the ascorbic acid.

Hence, we can assert that, the more the concentration of the ascorbic acid, the lower the rate of reaction. The rate of reaction depends on the slow step of a reaction.

We know that the molar mass of ascorbic acid is 176 g/mol. The mass of ascorbic acid is  6 g. Hence;

Number of moles of ascorbic acid = 6 g/176 g/mol = 0.034 moles

concentration of ascorbic acid = 0.034 moles/20 × 1 × 10-3 = 1.7 M
