sqrt(49) = 7
So this number is in the set of...
Natural numbersWhole numbersIntegersRational numbersReal numbersThe set of natural numbers is {1,2,3,...} and the set of whole numbers is {0,1,2,3,...}. Basically we just added in 0. Integers will be similar but we now have negative values too {..., -3, -2, -1, 0, 1, 2, 3, ...}
Rational numbers are anything of the form a/b with a,b being integers. In other words, if we can write the number as a fraction of two integers, then we have a rational number. In the case of 7, we have 7 = 7/1, so it is rational.
The set of real numbers includes every number type you have learned of so far (natural, whole, integer, etc). If you haven't learned about imaginary or complex numbers yet, then every number your teacher will go over is a real number.

You purchase 10,000 shares of a stock for $0.85 a share. One year later it is worth $0.95 a share. Find the profit if you sold at $0.95.
Answer:
Each share gained $0.10, which is an 11.76% increase (10/85).
The profit if the share is sold at $0.95/share, is $1000 and this can be determined by using the arithmetic operations.
Given :
You purchase 10,000 shares of a stock for $0.85 a share. After one year it is worth $0.95 a share.The following steps can be used in order to determine the profit if the share is sold at $0.95/share:
Step 1 - The arithmetic operations can be used in order to determine the profit if the share is sold at $0.95/share.
Step 2 - According to the given data, the cost of 10000 shares of a stock is $0.85 a share. So, let the total cost of 10000 shares be 'x'. So, the value of 'x' is:
[tex]x = 10000\times 0.85\\x = \$8500[/tex]
Step 3 - Now, after one year the shares price is $0.95 a share. So, let the cost of 10000 shares after one year be 'y'. So, the value of 'y' is:
[tex]y = 10000\times 0.95\\y = \$9500[/tex]
Step 4 - So, the profit if the share is sold at $0.95/share, is:
[tex]P = y-x[/tex]
[tex]P= 9500-8500[/tex]
[tex]P= \$1000[/tex]
Therefore, the profit if the share is sold at $0.95/share, is $1000.

Find the measures of angles 1 through 5 in the figure shown.
Its 4 PARTS
The measure of angle ∠1 is 44 degrees and the measure of angle ∠5 is 62 degrees.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
Angle ∠1 and 46° are complementary angles. Then we have
∠1 + 46° = 90°
∠1 = 44°
Angle ∠1 and ∠3 are vertically opposite angles. Then we have
∠1 = ∠3 = 44°
The sum of all the angles of the triangle is 180 degrees. Then we have
∠3 + 74° + ∠5 = 180°
44° + 74° + ∠5 = 180°
∠5 = 62°

A map is made of a park. The scale from the park to the map is 36 mi to 6 cm. The length of great oaks trail is 4.5 cm on this map. The scale from the same park to a different map is 24 mi to 3 cm. The length of salamander trail is 3.5 cm on that map. Which is the longer trail, great oaks trail or salamander trail?
Answer:
Salamander trail is longer than great oaks trail.
Step-by-step explanation:
We have the data from two different maps of the same park.
In the first map the length of great oaks trail is 4.5 cm
The scale from the park to the map is 36 mi to 6 cm ⇒
We can find the real length of great oaks trail writing the following equivalence :
[tex]\frac{36mi}{6cm}=\frac{x}{4.5cm}[/tex]
Where x is the real length of great oaks trail ⇒
[tex]x=\frac{(36mi).(4.5cm)}{6cm}=27mi[/tex]
We find that the real length of great oaks trail is 27 mi
In the second map the length of salamander trail is 3.5 cm
The scale from the park in the second map is 24 mi to 3 cm.
Again we can find the real length of salamander trail writing the equivalence :
[tex]\frac{24mi}{3cm}=\frac{y}{3.5cm}[/tex]
Where y is the real length of salamander trail ⇒
[tex]y=\frac{(24mi).(3.5cm)}{3cm}=28mi[/tex]
We find that the real length of salamander trail is 28 mi.
Therefore salamander trail is longer than great oaks trail.
I can’t figure out how to find the average.
Answer:
The student needs a minimum score of 81 on the fourth test to ensure a grade of at least a C in the class.
Step-by-step explanation:
Remember what an average is. (Look at the hint at the bottom of the problem.)
To find the average of a set of numbers, add all the numbers and divide by the number of numbers.
For example, if in a class you took 8 tests, the average of the 8 tests is the sum of the 8 scores divided by 8.
In this case, the student took 3 tests and is taking one more, so in the end there will be 4 scores. The number of tests is 4.
We know 3 of the 4 scores. We don't know the fourth score because he has not taken the test yet, so we use a variable to represent the unknown score. Let's call the score of the fourth test x.
To find the average of the 4 scores, we add them and divide the sum by 4.
The three known scores are 63, 62, 74.
The unknown score is x.
Add all 4 scores: 63 + 62 + 74 + x.
Now we divide the sum of the 4 scores by 4 to find the average of the 4 scores.
[tex] \dfrac{63 + 62 + 74 + x}{4} [/tex]
The expression above is the average of the 4 scores. We want the average to be at least 70, so we need the average to be greater than or equal to 70.
We get this inequality.
[tex] \dfrac{63 + 62 + 74 + x}{4} \ge 70 [/tex]
Now we solve the inequality for x.
Add like terms in the numerator.
[tex] \dfrac{199 + x}{4} \ge 70 [/tex]
Multiply both sides by 4.
199 + x = 280
Subtract 199 from both sides.
x = 81
Answer: The student needs a minimum score of 81 on the fourth test to ensure a grade of at least a C in the class.
Today only, a table is being sold at a 26% discount. The sale price is $481.
What was the price yesterday?
Answer:
The price yesterday was 650
Step-by-step explanation:
X is the price yesterday
There is a 26% discount
That means today we pay 100 -26 = 74 %
x* 74% = 481
.74x = 481
Divide each side by .74
.74x/.74 = 481/.74
x = 650
The price yesterday was 650

S'= ( 3,12 )
Answers:
S ' (3, 7)T ' (7, 7)U ' (8,2)V ' (5,2)Check out the diagram below
===================================================
Explanation:
When reflecting over horizontal lines like this, the x coordinate stays the same as the original point. Only the y coordinate changes.
To find what the y coordinate changes to, we need to measure the vertical distance from the point to the line. Point S has a y coordinate of y = -5 and the vertical distance to the line of reflection (y = 1) is |-5-1| = |-6| = 6 units. So we move 6 units up to go from point S to the line of reflection. We must move another 6 units to get to the location for S' where its reflected point would end up, which has y coordinate y = 7.
The same applies for the other points as well. Point T also goes up 6 units to get to y = 1, then it moves another 6 units to get to y = 7
Points V and U only move up 1 unit to get to the green dotted line of reflection. So they'll move only one additional unit to have their reflected points have y coordinates of y = 2.
The diagram hopefully visually summarizes everything discussed so far. The mirroring line cuts the distance from S to S' in half, same for T to T', and so on.
Find the unknown length y in the pair of similar triangles.
Step-by-step explanation:
If 2 triangles are similar then the ratio of any 2 sides of one triangles will be equal to the ratio of any 2 sides of the another triangle.
So,
[tex] \frac{30}{8} = \frac{20}{y} [/tex]
Cross-multiplying the denominators gives,
[tex]30y = 160[/tex]
[tex] = > y = \frac{160}{30} = \frac{16}{3} [/tex]
