Answer:

6% increase

Step-by-step explanation:

To find the percent increase, divide the difference by the original:

12/200

= 0.06

Multiply this by 100:

0.06(100)

= 6

So, the percent increase was 6%

Answer:

6.3

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

Given the expression a --b

Given that

a = 2

b = 1

Substitute into the expression

a--b

= 2 --1

= 2 - (-1)

= 2 + 1

= 3

Hence the required value is 3

Answer:

a=9, c=19

Step-by-step explanation:

Aight so basically in 30, 60, 90 triangles there is a formula for the sides

the hypotenuse(the longest side)=2a

The tiny side (the smallest side)=a

and the middle child =[tex]a\sqrt{3}[/tex]

Based on that we see that a is 9

and since c=2a then it's 18

Step-by-step explanation:

Step 1

The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:

5  5 2

Step 2

We can work out that the divisor (5) goes into the first digit of the dividend (5), 1 time(s). Now we know that, we can put 1 at the top:

1  

5  5 2

Step 3

If we multiply the divisor by the result in the previous step (5 x 1 = 5), we can now add that answer below the dividend:

1  

5  5 2

5  

Step 4

Next, we will subtract the result from the previous step from the second digit of the dividend (5 - 5 = 0) and write that answer below:

1  

5  5 2

- 5  

0  

Step 5

Move the second digit of the dividend (2) down like so:

1  

5  5 2

- 5  

2  

Step 6

The divisor (5) goes into the bottom number (2), 0 time(s), so we can put 0 on top:

1 0  

5  5 2

- 5  

2  

Step 7

If we multiply the divisor by the result in the previous step (5 x 0 = 0), we can now add that answer below the dividend:

1 0  

5  5 2

- 5  

2  

0  

Step 8

Next, we will subtract the result from the previous step from the third digit of the dividend (2 - 0 = 2) and write that answer below:

Answer:

40/12 or 3 1/3

Step-by-step explanation:

To multiply mixed numbers, first change any mixed number to an improper fraction. Then multiply the numerators together and the denominators together

1 1/3 as an improper fraction is 4/3 and 2 2/4 as an improper fraction is 10/4.

4*10=40

3*4=12

Answer:

Perimeter of the given figure = 28 units

Step-by-step explanation:

Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH

Length of AB = 4.5 units

Length of BC = 2 units

Length of CD = 2 units

Length of DE = 4 units

Length of EF = 5.5 units

Length of FG = 1.5 units

Length of HG = 1 units

Length of AH = 7.5 units

Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5

                                          = 28 units

Answer:

You get a D if you have a grade between 66 and 72.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Scores on the test are normally distributed with a mean of 79.3 and a standard deviation of 8.4.

This means that [tex]\mu = 79.3, \sigma = 8.4[/tex]

D: Scores below the top 80% and above the bottom 6%

So between the 6th and the 20th percentile.

6th percentile:

X when Z has a pvalue of 0.06. So X when Z = -1.555.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.555 = \frac{X - 79.3}{8.4}[/tex]

[tex]X - 79.3 = -1.555*8.4[/tex]

[tex]X = 66.2[/tex]

Rounds to 66

20th percentile:

X when Z has a pvalue of 0.2. So X when Z = -0.84.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.84 = \frac{X - 79.3}{8.4}[/tex]

[tex]X - 79.3 = -0.84*8.4[/tex]

[tex]X = 72.2[/tex]

Rounds to 72

You get a D if you have a grade between 66 and 72.

Answer:

there is no picture so I dont know what i have to do..

Answer:

1/3

Step-by-step explanation:

[tex][x^2 - ln(2/x)]/[3x^2 + 2x]\\[/tex]

∞/∞

[tex]\frac{d}{dx}[x^2-ln(2/x)] =2x+\frac{1}{x}\\ \frac{d}{dx}[3x^2+2x]=6x+2\\\frac{2x+\frac{1}{x}}{6x+2}[/tex]

Also ∞/∞

[tex]\frac{d}{dx}[2x+\frac{1}{x}]=2-1/x^2\\\frac{d}{dx}[6x+2]=6\\\\[/tex]

[tex]\lim_{x \to \infty} \frac{2-\frac{1}{x^2} }{6}\\=\frac{2}{6} \\=\frac{1}{3}[/tex]

Answer:

C

Step-by-step explanation:

Evolution is where organisms have developed over time from simple to complex. Therefore we can rule out D because older rock layers should have simple organisms and A because new rock layers should have more complex organisms. The previous organisms will be unlike those of today, therefore the correct answer is C.

Step-by-step explanation:

let the distance travel by both be a&b

a has a distance of d1 like wise b

speed=distanc/time

d1=2v

d2=4v

total distance

d1+d2=180

2v+4v=180

6v=180

v=30

d1=2*30

d1=60

d2=4*20

d2=120

now start u get u starting

not that there meet at same point so now calculate the time they will trave in there various direction

time=distance/velocity

but they but move at a standard velocity

Answer:

is this the full question:  Two boys A and B are at two diametrically opposite points on a circle. At one instant the two start running on the circle; A anticlockwise with constant speed v and B clockwise with constant speed 2v. In 2 minutes, they pass each other for the first time. How much later will they pass each other for the second time?

if yes than this is the answer:-

A speed = v

B speed = 2v

Time to meet = 2 minutes

d= pi r ( distance they have to run to meet)

they are running towards each other.

(2v+v)

speed = 3v

d=rt

pi*r = 3v*2

r= 6v/pi

circumference = 2* pi*r

=2*pi*(6v/pi)

=12v

...

Now distance to travel to meet = 12v

speed = 3v

t=d/r

t= 12v/3v

t= 4 minutes

I hope this helps a little bit.
