Suppose you estimated square root of 12 by averaging a square like rectngle.What would be a reasonable estimation?
Answer:
3.5.
Step-by-step explanation:
3^2 = 9
and 4^2 = 16 so the square root is between 3 and 4.
Take a rectangle 3.4 by 3.6:
the area = 3.4 * 3.6 = 12.24 so an estimate of the square root could be 3.5.
3.5 * 3.5 = 12.25.
If f(x) = x2 + x, find f(-3).

Work out the percentage change to 2 decimal places when a price of £198 is increased to £209.99.
Answer:
6.05%
Step-by-step explanation:
Initial price = £198
Increased price = £209.99.
We need to find the percentage change in the price. It can be calculated as follows :
%=(increase in amount)/(initial price) × 100
Increase in amount = 209.99 - 198
= 11.99
So,
[tex]\%=\dfrac{11.99}{198}\times 100\\\\=6.05\%[/tex]
So, the increase in price is 6.05%.
Answer:
6.05%

The area of Australia is 2.95 × 106 square miles. What is the approximate average number of people per square mile in Australia? Round to the nearest person
Answer:
9 people per square mile
Step-by-step explanation:
Given that:
Area of Australia = 2.95 * 10^6 mi²
Approximate average Number of people per square mile :
This can be obtained by taking the proportion of the population of Australia and the Area of the land mass
Approximate population of Australia : 25,499,884 ( data obtained from internet)
Average number of people per square mile :
Approximate population / Land Area
25,499,884 / 2.95 * 10^6
= 8.6440284
Hence, there will be approximately 9 people per square mile.

A small pool is being drained. There are 1,320 gallons of water remaining in the pool after 2 minutes and 1, 040 gallons after 9
minutes. How long would it take for the pool to be completely drained? (1 point)
Answer: 35 minutes
Step-by-step explanation:
For us to solve the question, we have to calculate the amount of gallons of water that is drained every minute. This will be:
= (1320 - 1040) / (9 - 2)
= 280/7
= 40 gallons per minute
Since we are told that 1,320 gallons of water remain in the pool after 2 minutes. This means that the total water in the pool at the beginning was:
= 1320 gallons + (40 × 2)
= 1320 gallons + 80 gallons
= 1400 gallons
The time taken for the pool to be completely drained will be:
= Total water in pool / Gallons drained per minute
= 1400 / 40
= 35 minutes
Find the angle measures. Justify your responses/
Given: a//b,, m3= 63 degrees.
Find: m6, m7
Answer:
Step-by-step explanation:
m<3=m<7=63
m<6+m<7=180
m<6=180-63
m<6=117
m<7=63
m<6=117
The measurement for ∠6 and ∠7 will be 63° and 117° respectively.
What is angle measurement?An angle measure is the measurement of the angle created by two rays or arms at a shared vertex in geometry. A protractor is used to measure angles in degrees (°).
As we know the alternate opposite angle of the parallel lines are equal;
∠3 and ∠7 are alternate opposite angles;
So that;
m∠3=m∠7=63°
The sum of the complementary angle is 180°.∠6 and ∠7 are complementary angle
m∠6+m∠7=180
m∠6=180°-63°
m∠6=117
Substitute the value to get ∠7
m∠7=63°
m∠6=117°
Hence the measurement for ∠6 and ∠7 will be 63° and 117°.

Step-by-step explanation:
Using f(x) = 5x + 4 and g(x) = x - 3,find: 1. f(g(6)) 2. g(f(-7)) 3. f(f(8)) 4. g(f(x))
Answer:
Part 1):
[tex]f(g(6))=19[/tex]Part 2):
[tex]g(f(-7))=-34[/tex]Part 3):
[tex]f(f(8))=224[/tex]Part 4):
[tex]g(f(x))=5x+1[/tex]Step-by-step explanation:
Considering the function
[tex]f(x) = 5x + 4[/tex]
[tex]g(x) = x - 3[/tex]
Part 1)
To evaluate [tex]f(g(6))[/tex], you must find [tex]g(6)[/tex]
so
[tex]g(x) = x - 3[/tex]
Put x = 6
[tex]g(6) = 6 - 3[/tex]
[tex]g(6) = 3[/tex]
Then
[tex]f(g(6))=f(3)[/tex]
[tex]=5(3)+4[/tex]
[tex]=19[/tex]
Therefore, [tex]f(g(6))=19[/tex]
Part 2)
To evaluate [tex]g(f(-7))[/tex], you must find [tex]f(-7)[/tex]
so
[tex]f(x) = 5x + 4[/tex]
Put x = -7
[tex]f(-7) = 5(-7) + 4[/tex]
[tex]=-35+4[/tex]
[tex]=-31[/tex]
Then
[tex]g(f(-7))=g(-31)[/tex]
[tex]= (-31) - 3[/tex]
[tex]=-34[/tex]
Therefore, [tex]g(f(-7))=-34[/tex]
Part 3)
To evaluate [tex]f(f(8))[/tex], you must find [tex]f(8)[/tex]
[tex]f(x) = 5x + 4[/tex]
Put x = 8
[tex]f(8)=5(8)+4=40+4=44[/tex]
Then
[tex]f(f(8))=f(44)=5(44)+4=220+4=224[/tex]
Therefore,
[tex]f(f(8))=224[/tex]
Part 4)
Evaluate
[tex]g(f(x))[/tex]
As
[tex]f(x) = 5x + 4[/tex]
[tex]g(x) = x - 3[/tex]
so
[tex]g(f(x))=g(5x+4)[/tex]
[tex]=(5x+4)-3[/tex]
[tex]=5x+4-3[/tex]
[tex]=5x+1[/tex]
Therefore,
[tex]g(f(x))=5x+1[/tex]

Answer:
[tex](x+5)+ \dfrac{2}{x+2}[/tex]
Step-by-step explanation:
Given
[tex]\dfrac{x^2+7x+12}{x+2}[/tex]
Required
Simplify and present your answer in
[tex]p(x)+\dfrac{k}{x+2}[/tex]
First, we need to expand and factorize the numerator:
[tex]\dfrac{x^2+7x+12}{x+2}[/tex]
Express 12 as 10 + 2
[tex]\dfrac{x^2+7x+10+2}{x+2}[/tex]
Split into two using brackets
[tex]\dfrac{(x^2+7x+10)+2}{x+2}[/tex]
Split to two fractions:
[tex]\dfrac{(x^2+7x+10)}{x+2}+\dfrac{2}{x+2}[/tex]
Factorize the numerator of the first fraction
[tex]\dfrac{(x^2+5x+2x+10)}{x+2}+\dfrac{2}{x+2}[/tex]
[tex]\dfrac{x(x+5)+2(x+5)}{x+2}+\dfrac{2}{x+2}[/tex]
[tex]\dfrac{(x+2)(x+5)}{x+2}+\dfrac{2}{x+2}[/tex]
The first fraction can be simplified to give:
[tex](x+5)+ \dfrac{2}{x+2}[/tex]
Hence, by comparison:
We have simplified the given expression to the required format of:
[tex]p(x)+\dfrac{k}{x+2}[/tex]
Which implies that:
[tex]p(x) = x + 5[/tex] and [tex]k = 2[/tex]

Gary is exercising on the stationary bike in his garage. He bikes 3.5 miles in 1/4 of an hour. How many miles could Gary bike in 3/4 of an hour at the same speed?
Given:
Gary bikes 3.5 miles in [tex]\dfrac{1}{4}[/tex] of an hour.
To find:
The distance covered by Gary in [tex]\dfrac{3}{4}[/tex] of an hour at the same speed.
Solution:
We have,
Distance covered in [tex]\dfrac{1}{4}[/tex] of an hour = 3.5 miles
Distance covered in [tex]1[/tex] hour [tex]=4\times 3.5[/tex] miles
Distance covered in [tex]\dfrac{3}{4}[/tex] of an hour [tex]=\dfrac{3}{4}\times 4\times 3.5[/tex] miles
[tex]=3\times 3.5[/tex] miles
[tex]=10.5[/tex] miles
Therefore, Gary could travel 10.5 miles in [tex]\dfrac{3}{4}[/tex] of an hour.
