Answer:

4, 9, 14, 19, 24, 29, 34, 39, 44, 49 and so on.

Step-by-step explanation:

1. If we use the rule starting from 4, we can add 15. That will give us 19.

2. Subtract 10, that will give us 9.

Now if we keep applying this rule we will keep going on to an infinite possibility of numbers.

So, the next number would be 9, then so on.

Answer:

9cups of dried split peas

8 qts of water

3 cups of chopped onion

4 cups chopped celery

8 lbs Ham shank

Step-by-step explanation:

The recipe serves 8 people, so to figure out how much you need to serve 32 people you multiply each measurment by 4 because 8 x 4=32.

2 1/4 x 4 = 9

2 x 4 = 8

3/4 x 4 = 3

1 x 4 = 4

2 x 4 = 8

Answer:

TanQ=20/21

Step-by-step explanation:

since we know that

TanQ= opposite/Adjacent

so we are going to calculate for the adjacent using Pythagoras theorem

a^2+b^2=c^2

20^2+b^2=29^2

400 + b^2=841

b^2=841-400

√b^2=√441

b=21

so our tanQ= opp/adj

tanQ=20/21

Answer:

we have the sides of the triangle, which are 14, 5, and 12 inches.

in a right angled triangle, the longest side is the hypotenuse

and pythagoras’s theorem is used/ can be used.

a^b + b^2 = c^2 where c is the hypotenuse

so we know a = 12, b = 5, and c = 14

now check whether the statement is true

we should get c = 14 if it’s a right triangle

12^2 + 5^2 = c^2

144 + 25 = c^2

169 = c^2

√169 = 13 = c

so since we got 13 for c and it’s not 14

we know that this isn’t a right angled triangle

Answer:

(23)(39)

Step-by-step explanation:

When you have to look for the "product" of two numbers, it implies multiplication.

With this, get rid of 23 + 39 = 62 as an answer.

Now simply enough, multiply 23 by 39,

23 * 39 = 897

Meaning that A. (23)(39) = 897 is the answer.

Using triangle concepts, it is found that the length of the third side of Damaris’s triangle could be any value greater than 3 inches and less than 15 inches.

In a triangle, the sum of the lengths of the two smaller sides has to be greater than the length of the greater side.

Considering 6 inches and 9 inches the smallest sides:

[tex]x < 6 + 9[/tex]

[tex]x < 15[/tex]

Considering 9 inches as the greater side:

[tex]x + 6 > 9[/tex]

[tex]x > 9 - 6[/tex]

[tex]x > 3[/tex]

The length of the third side of Damaris’s triangle could be any value greater than 3 inches and less than 15 inches.

Answer:

Step-by-step explanation:

Answer:

eight hundreths

Step-by-step explanation:

Its easy

The left side is equivalent to

[tex]\displaystyle \sum_{k=1}^n \frac1{k(k+1)}[/tex]

When n = 1, we have on the left side

[tex]\displaystyle \sum_{k=1}^1 \frac1{k(k+1)} = \frac1{1\cdot2} = \frac12[/tex]

and on the right side,

[tex]1 - \dfrac1{1+1} = 1 - \dfrac12 = \dfrac12[/tex]

so this case holds.

Assume the equality holds for n = N, so that

[tex]\displaystyle \sum_{k=1}^N \frac1{k(k+1)} =1 - \frac1{N+1}[/tex]

We want to use this to establish equality for n = N + 1, so that

[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac1{N+2}[/tex]

We have

[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = \sum_{k=1}^N \frac1{k(k+1)} + \frac1{(N+1)(N+2)}[/tex]

[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac1{N+1} + \frac1{(N+1)(N+2)}[/tex]

[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac{N+2}{(N+1)(N+2)} + \frac1{(N+1)(N+2)}[/tex]

[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac{N+1}{(N+1)(N+2)}[/tex]

[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac1{N+2}[/tex]

and this proves the claim.

The correct options are (a) and (d).

A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.

The given equation is as below,

2x + 3y = 12                              (1)

In order to find the correct answer all the options are considered one by one as follows,

(a) (0, 4)

Substitute x = 0 and y = 4 in equation to get,

LHS = 2× 0 + 3 × 4

       = 12

Since LHS = RHS, the given option is correct.

(b)  (3, 2)

Substitute x = 3 and y = 2 in equation to get,

LHS = 2× 2 + 3 × 2

       = 10

Since LHS ≠ RHS, the given option is not correct.

(c)  (2, 3)

Substitute x = 2 and y = 3 in equation to get,

LHS = 2× 3 + 3 × 3

       = 13

Since LHS ≠ RHS, the given option is not correct.

(d) (6, 0)

Substitute x = 0 and y = 4 in equation to get,

LHS = 2× 6 + 3 × 0

       = 12  

Since LHS = RHS, the given option is correct.

Hence, the points satisfying the given equation are (0, 4) and (6, 0).
