What is 11d - 88. In algebraic expressions
bekas [8.4K]
Simplifying
11d + -88 = 0

Reorder the terms:
-88 + 11d = 0

Solving
-88 + 11d = 0

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '88' to each side of the equation.
-88 + 88 + 11d = 0 + 88

Combine like terms: -88 + 88 = 0
0 + 11d = 0 + 88
11d = 0 + 88

Combine like terms: 0 + 88 = 88
11d = 88

Divide each side by '11'.
d = 8

Simplifying
d = 8

In triangle PQR, the angles are in the ratio 2 : 3 : 4. Find all the angles (urgent)
zvonat [6]

Answer:

40°, 60° and 80°

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 + 4 = 9 parts

Divide 180° ( sum of angles in a triangle) by 9 to find the value of one part of the ratio.

180° ÷ 9 = 20° ← value of 1 part of the ratio , then

2 parts = 2 × 20° = 40°

3 parts = 3 × 20° = 60°

4 parts = 4 × 20° = 80°

The angles in the triangle are 40°, 60°, 80°

8) A committee has fifteen members. There are two members that currently serve as the board’s chairman and vice chairman. Each m
pickupchik [31]

Answer:

The probability is    P(Z) = 0.0064

Step-by-step explanation:

From the question we are told that

  The number of members is  n = 15

Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

       K  =  ^{n}C_2 *  2!

Here C stands for combination hence we will be making use of the combination functionality in our calculator

      K  =  ^{15}C_2 *  2 * 1

=>  K  =  78  *  2 * 1

=>  K  =  156

Gnerally the number of outcome that matches the outcome required by the committee(Which is  reselecting the member who where the chairman and vice chairman of the board ) is   m =  1

Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

      P(Z) =  \frac{m}{K}

=>    P(Z) =  \frac{1}{156}

=>    P(Z) =  \frac{1}{156}      

 =>    P(Z) = 0.0064
