lesya [120]

Given:

Room is 5 meters by 8 meters.

Measure of squaree tiles is 14-inch.

$\begin{gathered} \text{Area of the room=5}\times8 \\ \text{Area of the room=}40m^2 \end{gathered}$ $1m^2=1550inch^2$ $\begin{gathered} \text{Area of each tile=14}\times14 \\ \text{Area of each tile=}196inch^2 \end{gathered}$ $\begin{gathered} \text{Number of tiles to floor the room=}\frac{40\times1550}{196} \\ \text{Number of tiles to floor the room}=316.3265 \end{gathered}$

Approximately 316 tiles are required to floor the room.

Which of the following is an arithmetic sequence? -7/11 6/11 -5/11 4/11....

Anastasy [175]

Answer:

the right answer is $\frac{3}{4} ,-\frac{3}{5},- \frac{3}{6} ,-\frac{3}{7}$

Step-by-step explanation:

to find the reason for the sequence, the following formula must be used;

q = t2 / t1

where t2 is equal to the second value of the sequence and t1 to the first value.

q= t2/t1

q = $\frac{-\frac{3}{5} }{-\frac{3}{4} } = \frac{12}{15} =\frac{4}{5}$

Complete the steps of the derivation of the quadratic formula step 1: (x+b/2a)^2-b^2-4ac/4a^2=0

CaHeK987 [17]

(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2

Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]

Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a

Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
