Problem 1
Answer: 7.3Explanation: Apply the square root to the area to get the side length. This only applies to areas that are squares (hence the name).
==================================================
Problem 2
Answer: C) 1.3Explanation: Use your calculator to find that choices A,B,D plugged into the square root function yield terminating decimal values. "Terminating" means "stop". This implies that they are perfect squares (though not perfect squares in the sense of whole number perfect squares which you may be used to). Choice C is the only value that has a square root that leads to a non-terminating decimal. The digits of this decimal go on forever without any pattern. The value is irrational.
sqrt(5.29) = 2.3 terminating decimalsqrt(13.69) = 3.7 terminating decimalsqrt(1.3) = 1.140175425 keeps going forever without any patternsqrt(0.09) = 0.3 terminating decimal==================================================
Problem 3
Answer: 23.6 feet approximatelyExplanation: Apply the square root to 15.5 to get roughly 3.937; this is the approximate side length of one square. Six of these tiles placed together will lead to a total length of roughly 6*3.937 = 23.622 which rounds to 23.6 feet. Like with problem 1, the square root being used like this only works for square areas.
A two-tailed test is one where: A. negative sample means lead to rejection of the null hypothesis B. results in either of two directions can lead to rejection of the null hypothesis C. results in only one direction can lead to rejection of the null hypothesis D. no results lead to the rejection of the null hypothesis
Answer:
Step-by-step explanation:
In a two tailed test, the alternative hypothesis contains the "unequal to" symbol. It is used when we are testing for a difference. This means that the test is regardless of direction. Therefore, the left tail and the right tail of the curve is considered when making decisions. This simply means that there are two critical regions for the test. Therefore, a two-tailed test is one where:
B. results in either of two directions can lead to rejection of the null hypothesis

To find:
The graph of inequality on the number line.
Solution:
First of all, let us simplify the inequality.
[tex]0.3(x -4) > -0.3[/tex]
Dividing it with 0.3 on the both sides:
[tex]x -4 > -1\\\text{Adding 4 on both sides}\\\Rightarrow x > 3[/tex]
i.e. all the values x > 3 will be our solution. There is no equal sign in the inequality so 3 will not be included in the solution.
Please refer to the attached image for the solution graph of the given inequality.
3 has an empty circle drawn over it which signifies that 3 is not included in the solution set.
Red line shows that all the values greater than 3 are included in the solution.

The graph of F(x),shown below,has the same shape as the graph of G(x)=x^4, but it is shifted 2 units to the right. What is it’s equation?
F(x) =____
Hey there! :)
Answer:
A. [tex]f(x) = (x - 2)^{4}[/tex]
Step-by-step explanation:
Recall that the transformation form of a polynomial with degree four is:
[tex]f(x) =[/tex] ±[tex]a(b(x-h))^{4} +k[/tex]
In this instance, we will need to use the h value, or the horizontal shift.
It is given that there is only a horizontal shift of 2 units to the right, or h = 2. Plug this into the equation:

PLEASE HELP !!!! On the grid provided, draw a nonsymmetric four sided figure in Quadrant II labeled ABCD. The vertices on the figure should be integer ordered pairs. Your figure must be translated, reflected, and rotated (the order of these is your choice), your transformations must take you to Quadrant I, Quadrant III, and Quadrant IV but the final figure must end up in Quadrant I. After the first transformation, label the figure A׳B׳C׳D׳. After the second transformation, label the figure״A״B״C״D״. After the third transformation, label the figure A׳׳׳B׳׳׳C׳׳׳D׳׳׳
Answer:
The transformations included are
1) Reflection about the y-axis
2) 90° clockwise rotation
3) Reflection about the y-axis
4) Translation T(0, 21)
5) Translation T(14, 0)
Step-by-step explanation:
Reflecting a pre-image about the y-axis gives;
Point (x, y) becomes (-x, y)
Rotation 90° clockwise gives (x, y) becomes (-y, x)
Translating (x, y) by T(0, 21) gives (x, y + 21)
Translating (x, y) by T(14, 0) gives (x + 14, y).

An ISOSCELES right triangle has a hypotenuse of x√6 units what is the area of the triangle?
Answer:
x^2/2
Step-by-step explanation:
Alright, lets go.
Isosceles right triangle means a 45-45-90 triangle.
In a 45-45-90 triangle, the hypotenuse is [tex]\sqrt{2}[/tex] times the leg.
Therefore, the length of the leg is x√3.
The area of a triangle is b(h)/2
In a 45-45-90 right triangle, the area is equal to the length of a leg squared/2
A leg = x√3. (x√3)^2 = 3x^2
The area of the triangle is 3x^2/2

A passenger ship and an oil tanker left port sometime in the morning; the former headed north, and the latter headed east. At noon the passenger ship was 40 mi from port and moving at 30 mph, while the oil tanker was 30 mi from port and moving at 20 mph. How fast was the distance between the two ships changing at that time
Answer:
distance between the two ships changing at that time is 36 mph
Step-by-step explanation:
given data
ship = 40 mi from port
ship moving = 30 mph
oil tanker = 30 mi from port
oil tanker moving = 20 mph
solution
we will apply here pythagoras theorem so we get here
x² + y² = L² .....................1
here x is distance of ship from port
and y is distance of oil tanker from port
and L is distance between oil tanker and ship
so put here value and we get
40² + 30² = L²
L = 50 mile
now we differentiate equation1 with respect to time t
[tex]2x\ \frac{dx}{dt} + 2y\ \frac{dy}{dt} = 2L\ \frac{dL}{dt}[/tex] ...............2
put here value and we get
40 × 30 + 30 × 20 = 50 × [tex]\frac{dL}{dt}[/tex]
[tex]\frac{dL}{dt}[/tex] = 36 mph
so distance between the two ships changing at that time is 36 mph

10. Five companies employed 2340, 3455, 675, 960 and 1350 workers. The first company
laid off 1 worker for every 5 workers, while the other three recruited 2 new workers for
every 3
THIS IS THE COMPLETE QUESTION
Five companies employed 2340, 3455, 675, 960 and 1350 workers. The first company laid off 1 worker for every 5 workers, while the other three recruited 2 new workers for every 3. a) What was the total number of workers at the beginning c) How many people: i) Lost job ii) Got job d) What was the total number of workers finally
Answer:
a) 8780
ci) 1159
cii) 1990
d) 9611
Step-by-step explanation:
a) What was the total number of workers at the beginning?
The Total number of workers at the beginning can be calculated by adding the number of workers which are
= 2340 + 3455 + 675 + 960 + 1350
= 8780
c) How many people: i) Lost job
TO calculate the number that lost their job, we know that the first company laid off 1 worker for every 5 workers,
But the employed workers were 2340 and 1 worker laid for every 5 workers. Hence we can say that
2340/5 = 468
Therefore, 468 lost job in the first company.
To calculate for the second company,
from the question we know that Workers employed were 3455 and 1 worker laid for every 5 workers. Then we can say that
3455 / 5 = 691
Therefore, 468 lost job in second company.
After getting the number that lost their job in the two companies we can now say that the total workers that lost job:
=468 + 691 = 1159
ii) To calculate the number that Got job
We know that other three companies recruited 2 new workers for every 3, then the number of people who got job in these three companies can be calculated as;
= [(675 * 2 )+ (960 *2) + (1350 *2) ]/ 3
= (1350 + 1920 + 2700) / 3
= 5970 / 3
= 1990
Therefore, we have 1990 people that got the job.
d) the total number of workers finally can be calculated by summing up the the workers who got job in the workers at beginning then minus the number ofworkers who lost job ,
We know that the Total number of workers:
8780 number of workers at the beginning
1159 is for companies who lost job
1990 is for companies who got job
total number of workers finally:
= (8780 )+ (1990) -( 1159)
= 9611
Therefore, the total number of workers finally are 9611.

what is the sum of all possible multiples of 5 less than 500
Answer:
We need to find 5 + 10 + 15 + ... + 485 + 490 + 495. There are 99 numbers that are being added. To add this we can do 5 + 495, 10 + 490, 15 + 485 and so on. These pairs have a sum of 500 and since there are 98 / 2 = 49 pairs their sum is 500 * 49 = 24500. Since there is an odd number of numbers that are being added, there is one number that does not belong to a pair. That number is the 50th number in the list which is 50 * 5 = 250. Therefore the answer is 24500 + 250 = 24750.

A block measure 22cm by 11cm by 7cm. How many of these blocks will be needed to build a wall 5 1/2m long, 22cm thick and 3 1/2m high.
Answer:
The number of blocks that will be needed to build the wall is 2500
Step-by-step explanation:
The number of blocks that will be needed to build the wall is;
[tex]n = \frac{volume of wall}{volume of block} \\volume = l *b*h\\[/tex]
given the dimensions of the block and wall as;
block = 22cm by 11cm by 7cm
wall = 5 1/2m long, 22cm thick and 3 1/2m high. = 550cm by 22cm by 350cm
substituting into the equation, we have;
[tex]n = \frac{volume of wall}{volume of block} \\volume = l *b*h\\\\n = \frac{550*22*350}{22*11*7} \\n = 2500[/tex]
The number of blocks that will be needed to build the wall is 2500
