Answer:

n=11

Step-by-step explanation:

19+n=30

n=30-19

n=11

Answer:

n=11

Step-by-step explanation:

In order to solve this equation, we need to find out what n is. We have to get n by itself on one side of the equation. Perform the inverse operations to both sides of the equation.

19+n=30

19 is being added to n. The inverse of addition is subtraction. Subtract 19 from both sides.

19-19+n=30-19

n=30-19

n=11

Let's check out solution. Plug 11 in for n in the original equation.

19+n=30

19+11=30

30=30

The statement above is true, so we know our solution is correct.

As we know that significant figures are the accurately known digits and the first doubtful digit in an expression.

0.051866

when the dropping digit is greater than 5 than the last retained digit increases by 1 e.g. 0.051866 is rounded to 0.05187

again follow the rule 0.05187 is rounded to 0.0519

Step-by-step explanation:

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example:

A certain number is divided by half, the result is added to itself to give 6, what is the number?

Solution:

- Let the number be x

- Divide x by half:

In word problem, extra caution is to be taken, as misinterpretation can be very chaotic. Dividing a number by 2, is totally different from dividing the number by half.

4 divided by 2 is 4÷2 = 2

4 divided by half is 4÷½ = 4×2/1 = 8

2 and 8 are different, reason to be cautious.

So dividing x by half, we have:

x ÷ 1/2 = x × 2/1 = 2x.

- Now, what we have is

2x + x = 6

Solving this equation, we can obtain the value of x.

2x + x = 6

3x = 6

Dividing both sides by 3

3x/3 = 6/3

x = 2.

Therefore, the solution to the word problem is x = 2.

Answer:

  23.  0.4583 seconds

  24.  0.0107 seconds

Step-by-step explanation:

The problem statement tells you how to work it. You need to convert speed from miles per hour to feet (or inches) per second.

 90 mi/h = (90·5280 ft)/(3600 s) = 132 ft/s = (132·12 in)/s = 1584 in/s

__

23. The time it takes for the ball to travel 60.5 ft is ...

  time = distance/speed

  time = (60.5 ft)/(132 ft/s) = 0.4583 s

It takes 458.3 milliseconds to reach home plate.

__

24. time = distance/speed

  time = (17 in)/(1584 in/s) = 0.0107 s

The ball is in the strike zone for 10.7 milliseconds.

Answer:

The speed increases (45—>47—>49) then decreases (48—>47) over time.

Step-by-step explanation:

The table that represents the speed of the car that increases and decreases as time increases is Table B.

Option B is the correct answer.

Speed is the ratio of the given distance and time.

It shows how fast an object is moving at a given time.

The formula is Distance / Time.

We can find the distance or time when the required values is given using this formula.

We have,

From the table,

We see that,

Time      5     6     7      8     9

Speed   45   47   49   48   47

This indicates that,

As time increases, the speed increased from 5 minutes to 7 minutes and decreases from 7 minutes to 9 minutes.

Thus,

The table that represents the speed of the car that increases and decreases as time increases are in Table B.

Answer:

Step-by-step explanation:

Since the y-int. is 2 we know that the coefficient of the exponential term is 2, which eliminates B and D. Since f(x) decreases from left to right, the number in the parentheses has to be less than 1, so the answer is f(x) = 2 * (0.25)^x.

[tex]B-C=\{2,4,6\}[/tex]

Step-by-step explanation:

We are given the following sets:

[tex]A=\{1,2,3,4\}\\ B=\{2,4,6\}\\ C=\{1,3,5,7\}\\ and\\U=\{1,2,3,4,5,6,7\}[/tex]

To find: [tex]B-C = ?[/tex]

Solution:

Here, we are given 4 sets,

The universal set, U and its 3 proper subsets A,B and C.

Proper subsets are the subsets which have at least one element which is extra in the super set.

Now, let us have a look at the definition of 'minus' in terms of sets.

Minus is defined as the set of elements which contains the elements of first set which are not present in the other set.

OR

The common elements are not written.

For example:

P = {10,20,30}

Q = {10,40,70}

P - Q = {20,30}

Common element(s) of  P [tex]\cap[/tex] Q = {10} is/are not written in P-Q.

Here, there are no common elements in B and C.

[tex]\therefore B-C = B[/tex]

OR

[tex]B-C=\{2,4,6\}[/tex] is the correct answer.

✔ 128

into the  

✔ small

tank.

After the 32 minutes, how much oil is in the large tank?  

✔ 472

gallons

Step-by-step explanation: Just did it on Edge

Using the given flow rate and time we found that after a period of 32 minutes 128 gallons of oil is moved from large tank to small one. The oil  in large tank after 32 minutes is 472 gallons.

Rate of work done is the amount of work done per unit time

rate of work done = amount of work / time taken

Given that flow rate is positive when oil is moving in large tank and rate of flow is negative when oil is moving in small tank

Given that flow rate is recorded -4 gallons per minute, which is negative .

It means that the oil is flowing in the small tank.

Rate of flow, r is 4 gallons per minutes , here work is oil flowing into a tank

Rate of flow, r  = oil flown in a tank / time taken

Given that time, t = 32 minutes

∴ rate of flow × time taken = Oil flown in small tank

⇒ r× t = oil flown in small tank = 4 × 32 = 128 gallons

Initially oil in large tank = 600 gallons

Thus, 128 gallons are moved from large tank to small tank in 32 minutes

After 32 minutes remaining oil in large tank = 600 - 128 = 472 gallons

Answer:

D

Step-by-step explanation:

Let x be Bill’s scores.

Let y be Theo’s scores.

x + y = 90

x² = y

Solve for x in the second equation.

x = √y

Put x as √y in the first equation and solve for y.

√y + y = 90

√y = 90 - y

y = (90 - y)²

y = - y² - 180y - 8100

0 = -y² - 181y - 8100

0 = (-y+81)(y-100)

-y+81=0

y = 81

y - 100 = 0

y = 100

100 does not work if we plug in to check, so y is 81.

y = 81

Put y as 81 in the first equation and solve for x.

x + 81 = 90

x = 9

Bill scored 9 goals and Theo scored 81.

Answer:

[tex]n^2+3[/tex]

Step-by-step explanation:

4, 7, 12, 19, 28

The differences are 7-4=3, 12-7=5, 19-12=7, 28-19=9.

This is an arithmetic sequence since the differences are constant.

There must be [tex]n^2[/tex] in the nth term.

These are the next terms in the sequence:

4, 7, 12, 19, 28, 39, 52, 67, 84, 103, 124, 147, 172, 199, 228, 259, 292, 327, 364, 403, 444, 487, 532, 579, 628, 679, 732, 787, 844, 903, 964, 1027, 1092, 1159, 1228, 1299, 1372, 1447..

[tex]n^2 +c=4[/tex]

[tex]1^2+c=4[/tex]

[tex]c=4-1[/tex]

[tex]c=3[/tex]

Therefore, the nth term is [tex]n^2+3[/tex].

Answer:

nth term = n^2 + 3.

Step-by-step explanation:

4 7 12 19 28

The differences  are in an arithmetic sequence so this is a quadratic sequence,

- the differences are 3, 5, 7, 9... which is an A.S.

The  common difference of the A.S. is 2 so there is n^2 in the formula for the nth term.

By inspection , we see that each term is 3 more than  the term number squared.

1^2 + 3 = 4

2^2 + 3 = 7

3^2 + 3 = 12  

4^2 + 3 = 19   and so on.

Answer:

68°

Step-by-step explanation:

a triangle hold 180° so 180-43=137 and G and H are almost the same value where G is 69° and H is 68°

Step-by-step explanation:

x°+43°+(x-1)°=180°(sum of all the interior angle of triangle is 180°

2x°+42°=180°

2x°=180°-42°

2x°=138°

x=138°/2°

:. x=69°

Now,

angle H= (x-1)°=69°-1°=68°
