4.36 + 2.89 is equal 7.25 and 6.8 - 5.42 is equal 1.38
Step-by-step explanation:
4.36 + 2.89 = 7.25
6.8 - 5.42 = 1.38
Answer:
7.25
1.38
Step-by-step explanation:
a) For first addition
4.36 + 2.89
Start adding from the right side. Take the last number and add them together.
9+6 = 15.................. write 5 and keep 1
Bring forward the kept "1"
3+8 + 1 = 12............. write 2 and keep 1
Bring forward the kept "1"
4+2 + 1 = 7...............write 7
∴ 7.25
b) For second subtraction
6.8 - 5.42 = 1.38
Start from the right side of each number
0 - 2 requires that you borrow "1" from "8" now turning "0" to "10" and "8" to "7".
now, 10 - 2 = 8...........write 8
7 - 4 = 3.............write 3
6 - 5 = 1..............write 1
∴ 1.38
if a pair of 1-6 number generators is tossed once, what is the propabilitly that the total number rolled would be..1?.... 2?.... 3?
Probability that the total number rolled would be 1 , 2 , 3 is [tex]\frac{1}{6}[/tex] or 0.167 each .
Step-by-step explanation:
Here we have , a pair of 1-6 number generators is tossed once, . We need to find that what is the probability that the total number rolled would be..1?.... 2?.... 3?. Tossed once, and number of outcomes are { 1,2,3,4,5,6 } out of which we need to find probability that the total number rolled would be 1 , 2 , 3 .

On 1st January 2016 Li bought a boat for $170000
The value of the boat depreciates by 8% per year.
Work out the value of the boat on 1st January 2019
Give your answer correct to the nearest dollar.
After a depreciation of 8% per year for 3 years, the value of Li's boat depreciates to approximately $136258, according to the formula for calculating the value of an asset after a certain number of years of depreciation.
Explanation:The value of an asset after a certain number of years, taking into account annual depreciation, can be calculated using the formula: Preliminary Value x ((100 - Depreciation Rate) / 100) ^ Years Of Depreciation.
Given that the initial value of Li's boat was $170,000 and it depreciated by 8% each year, we can substitute these values into the formula to find the value of the boat on 1st January 2019 (after 3 years).
So, the boat's value would be: $170,000 x ((100 - 8) / 100) ^ 3. This simplifies to $170,000 x (0.92) ^ 3, yielding a final value of approximately $136258

x - y = 19 +
--------------
2x = 116
x = 58
--------------
y = 97 - 58
y = 39
To find the ages of two friends based on the sum and difference of their ages.
Explanation:James and Tyson are two friends whose ages sum up to 97 and have a difference of 19. To find their ages, we can set up a system of equations:
Let's denote James' age as x and Tyson's age as y.We have the equations: x + y = 97 and x - y = 19.Solving these equations simultaneously gives x = 58 and y = 39.Therefore, James is 58 years old, and Tyson is 39 years old.

Help. Interpreting Graphs Of Proptional Relasionships. !
Graphs of proportional relationships visually depict how two or more variables are interrelated using line graphs, pie graphs, and bar graphs. Line graphs show direct relationships with a constant rate of change, pie graphs represent portions of a whole, and bar graphs compare quantities through the height of bars.
Explanation:When interpreting graphs of proportional relationships, it's essential to recognize that these graphs illustrate how two variables correlate with one another. In line graphs, a straight line that passes through the origin indicates a direct proportionality, meaning as one variable increases, the other increases at a constant rate. For instance, if a line graph shows the relationship between hours worked and income earned, the line's slope denotes the rate of earning per hour, showcasing a proportional increase in income with more hours worked.
Pie graphs are used to represent how a whole is divided into parts, with the size of each 'slice' showing the percentage of the total. An example could be a budget allotment where each slice represents what percentage of the budget is spent on specific categories, like marketing or research and development.
Lastly, bar graphs can also indicate proportional relationships through the height of the bars. For example, if a bar graph displays the population sizes of different countries, each bar's height is proportional to the population of that country. When bars are segmented, they can show subgroups within that population, such as age demographics or income brackets.
Two sides of a triangle measure 10 cm and 18 cm. Which could be the measure of the third side of the triangle?
6 cm
8 cm
12 cm
30 cm
Answer:
12cm is the answer as the two lowest sides must be more in size than its longest side. 10+12=22
Step-by-step explanation:
Final answer:
The possible length of the third side of a triangle with two sides measuring 10 cm and 18 cm, according to the Triangle Inequality Theorem, must be more than 8 cm and less than 28 cm. Therefore, the valid measures among the given options are 8 cm and 12 cm.
Explanation:
The question concerns determining the possible length of the third side of a triangle when the lengths of the other two sides are given. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Using this theorem, if we have sides measuring 10 cm and 18 cm, the possible lengths of the third side could be more than the difference of the two given sides and less than their sum. Therefore, the third side must be greater than 8 cm and less than 28 cm.
Among the given options, 6 cm is not a possible length because it is less than 8 cm and would not satisfy the Triangle Inequality Theorem. Similarly, 30 cm is not a possible length because it exceeds the sum of the two given sides. However, both 12 cm and 8 cm are possible lengths for the third side since both values are within the allowable range.

=============================================
Why this is the answer:
The rectangle has 3 circles packed inside it each with the same radius r. The diameter of each circle is 2r, so 3 of them result in a total rectangle length of 3*2r = 6r.
While one circle has a circumference of C = 2*pi*r = 2*3.14*r = 6.28r
Comparing 6.28r and 6r, we see that 6.28r is larger than 6r
6.28r > 6r
6.28 > 6 ... dividing both sides by r (the inequality sign doesn't change because r > 0)
This is true for any value of r.

Use the data set to answer the question.
{122,132,155,198,213,225,261,280}
What is the mean absolute deviation for the data set?
Enter your answer as a number rounded to the nearest tenth, like this: 42.5
The mean absolute deviation for the given data set is 45.1.
Explanation:To find the mean absolute deviation for a given data set, follow these steps:
Find the mean of the data set by adding up all the values and dividing by the total number of values.
For each value in the data set, find the absolute difference between the value and the mean.
Find the average of these absolute differences by summing them up and dividing by the total number of values.
In this case, the data set is {122,132,155,198,213,225,261,280}.
The mean of this data set is 196. The absolute differences from the mean are: 74, 64, 41, 2, 17, 29, 65, 84.
The average of these absolute differences is 45.1. Therefore, the mean absolute deviation for the data set is 45.1.
Each lapel on a suit jacket is in the shape of a triangle.the three angles of each triangle measure 47 , 68 and 65. classify the triangle by its angles
The type of triangle is acute angled triangle.
Solution:
Let us first define the type of triangles based on angles.
If all angles of a triangle are less than 90°, then it is acute angled triangle.
If any one angle of a triangle is exactly 90°, then it is right angled triangle.
If any one angle of a triangle is more than 90°, then it is obtuse angled triangle.
Given angles of a triangle:
47°, 68° and 65°
Here all the three angles are less than 90°.
Hence it is a acute angled triangle.

in a certain clothing store,6 shirts and 3 ties cost $79.50 ,and 3 shirts and 2 ties cost $41. determine the cost of each shirt.
Answer:
Each shirt cost $12
Step-by-step explanation:
First, we have to interpret this question and turn each to an equation, letting shirts represent the letter s and ties represent the letter t.
6 shirts and 3 ties cost $79.50 would be interpreted to 6s+3t=79.5 ,and 3 shirts and 2 ties cost $41 would be interpreted to 3s+2t=41
Hence we have two equations, and we solve them simultaneously.
6s+3t=79.5 (Equation 1)
3s+2t=41 (Equation 2)
We can either use the substitution method or the elimination method but for the sake of this question, we use the Elimination method.
6s+3t=79.5 (Equation 1)
3s+2t=41 (Equation 2)
We multiply equation 1 by 2 and we multiply equation 2 by 3, I'm prefer to eliminate the
2(6s+3t=79.5)
12s+6t=159 Equation 3
3(3s+2t=41)
9s+6t=123 Equation 4
We subtract equation 4 from equation 3.
12s+6t=159
9s+6t=123
12s-9s=3s
6t-6t=0
159-123=36
We therefore have
3s=36
Divide both sides by 3
s=36/3
s=12
One shirt cost $12

A cone-shaped tent has a diameter of 12 ft and a height of 6 ft. What is the approximate volume of the tent? Question 2 options: 226 ft3 679 ft3 905 ft3 2714 ft3
The volume of the tent is option A) 226 ft³
Step-by-step explanation:
The given data are,
A cone-shaped tent has a diameter of 12 ft.The height of the cone is 6 ft.To find the volume of the tent :
The volume of the tent can be found using the formula for volume of the cone, since the tent is in the shape of a cone.
Volume of the cone = (1/3)πr²h
where, r is the radius of the cone. The diameter is given as 12 ft. Therefore, to find the radius = diameter /2 = 12/2 = 6 ft.
The radius, r = 6 ft.
The height h of the cone is h= 6 ft.
Volume of the cone = (1/3)× 3.14× 6²× 6.
⇒ (1/3)× 3.14× 216
⇒ 678.24 / 3
⇒ 226.08 (which is approximately 226)
⇒ 226 cubic. ft
Therefore, the volume of the tent is option A) 226 ft³

A square and a regular hexagon have side of the same length. The perimeter of the square increased by 48 units will be equal to the perimeter of the hexagon. What is the x, the length of the side of the hexagon or square
The length of the side of the hexagon or square is 24 units.
Step-by-step explanation:
It is given that, a square and a regular hexagon have side of the same length.
The length is not given in the problem. So, let us assume the length of the side of hexagon or square as 'x'.
The additional information given is that, the perimeter of the square increased by 48 units will be equal to the perimeter of the hexagon.
The perimeter of the square = 4 × length of the side.Then, the perimeter of the square increased by 48 units = (4x + 48).The perimeter of the hexagon = 6 × length of the side.Therefore, the perimeter of the hexagon = 6x.To calculate the length x of square and hexagon :
Comparing both the perimeters of square and hexagon,
⇒ (4x + 48) = 6x
⇒ 48 = 6x-4x
⇒ 2x = 48
⇒ x = 48/2
⇒ x = 24 units.
The length of the side of the hexagon or square is 24 units.

Find the perimeter of the triangle below. Then, explain the steps you used to find the perimeter
The perimeter of the triangle = 60 cm
Solution:
The given triangle is a right triangle.
Base of the triangle = 15 cm
Hypotenuse = 25 cm
Let the unknown side of the triangle be x.
Using Pythagoras theorem,
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.
[tex]x^2+15^2=25^2[/tex]
[tex]x^2+225=625[/tex]
Subtract 225 from both sides,
[tex]x^2=400[/tex]
Taking square root on both sides, we get
x = 20
The unknown side of the triangle is 20 cm.
The perimeter of the triangle = Sum of the sides of the triangle
= 15 cm + 25 cm + 20 cm
= 60 cm
The perimeter of the triangle = 60 cm
