Two-thirds of a number is equal to negative one-fifth. What is the number
answers: -7 1/2, -3/10, -2/15, -3 1/3
Answer: -7 1/2
Step-by-step explanation:
The required number would be -3/10.which is the correct answer would be option (B).
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
We have been given that two-thirds of a number is equal to a negative one-fifth.
Let the number would be x
According to the given question, the required solution would be as:
⇒ (2/3)x = -1/5
Divided by (2/3) both sides of the above equation,
⇒ (2/3)x/ (2/3) = (-1/5)/(2/3)
⇒ x = (-1/5)/(2/3)
Reciprocal the term in the numerator,
⇒ x = (-1/5) × (3/2)
Apply the multiplication operation, and we get
⇒ x = -3/10
Therefore, the required number would be -3/10.
Hence, the correct answer would be option (B).

After 4 days, a plant is measured to be 10 inches tall. Later, after a total of 20 days, then height is measured to be 18 inches. What is the rate of growth for the plant? This is supposed to be for slopes in Algebra 1.
Given :
After 4 days, a plant is measured to be 10 inches tall.
Later, after a total of 20 days, then height is measured to be 18 inches.
To Find :
The rate of growth for the plant.
Solution :
We know, rate is given by :
[tex]Rat e=\dfrac{\text{Change in height}}{\text{Time taken}}\\\\Rate = \dfrac{18-10}{20-4}\\\\Rate = 0.5 \ inch/day[/tex]
Therefore, rate of increase of height is 0.5 inch/day .
Hence, this is the required solution.

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]

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.
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.

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%

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°.

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.

Write the slope-intercept form of the equation of the line described.
1) through (2, 2), parallel to y=x+4
Answer:
Slope intercept form: y=mx+b; where m is the slope and B is the y intercept
For 2 lines to be parallel they must have the same slope. Thus, the slope of the new line is going to be 1.
To find the y intercept plug in the slope and the x, y into the equation y=mx+b:
y=mx+b
y=1x+b
2=1(2)+b
2=2+b
0=b
b=0
Now that we have your slope and y intercept we can make the equation:
y=1x+0
y=x
