The sum of 5 consecutive integers is 110.<br>What is the fourth number in this sequence?​
Brut [27]

<u>Given</u>:

The sum of 5 consecutive integers is 110.

Let the sequence be x, x + 1, x + 2, x + 3, x + 4

We need to determine the fourth number in the sequence.

<u>Value of x:</u>

Since, the sum of 5 consecutive integers is 110.

Thus, we have;

x+x+1+x+2+x+3+x+4=110

Adding the like terms, we have;

5x+10=110

       5x=100

         x=20

Thus, the value of x is 20.

<u>Fourth term:</u>

The fourth term of the sequence is x + 3

Substituting x = 20 in the term, we get;

Fourth term = 20 + 3 = 23

Thus, the fourth term of the sequence is 23.

Urgent please!!! I really don’t understand it, tysm to anyone who can answer thissss :))))
Tomtit [17]

Given:

The frequency distribution table.

To find:

The mean average score on a test.

Solution:

The frequency distribution table is

Marks (x_i)                   Frequency(f_i)                  f_ix_i

     x                                     a                               xa

     y                                     b                               yb

     z                                     c                               zc

  Sum                              a+b+c                          xa+yb+zc

Now, the mean average score on the test is

Mean=\dfrac{\sum f_ix_i}{\sum f_i}

Mean=\dfrac{xa+yb+zc}{a+b+c}

Therefore, the mean average score on the test is \dfrac{xa+yb+zc}{a+b+c}.

Each side of a square is increasing at a rate of 7 cm/s. At what rate is the area of the square increasing when the area of the
Vilka [71]

Answer:

Step-by-step explanation:

The rate if increase of side of square is 7cm/s

dL/dt=7

At what area is the area increasing

dA/dt=?

Areas of square is give to be 36cm²

Analysis

Let L be the length of each side of the square, a square has equal side.

Area of square is give as L²

Area=L²

L²=36

i.e L=√36

L=6cm

Therefore at t=0 L=6cm and A=36cm²

A=L²

dA/dL=2L

Given that, dL/dt=7

Multiply the two differential together

dA/dt= dA/dL × dL/dt

dA/dt= 2L × 7

dA/dt= 2×6×7

dA/dt= 84cm²/s

The rate of increase of the square is 84cm²/s
