3. The floor of building consists of 2000 tiles which are rhombus shaped and
each of its diagonals are 40 cm and 25 cm in length. Find the total cost of
polishing the floor, if the cost per m2 is Rs/5.
Answers
Answer:
Total cost of polishing the floor is Rs/500.
Step-by-step explanation:
The floor consists of 2000 tiles which have the shape of a rhombus.
Area of rhombus = [tex]\frac{d_{1} *d_{2} }{2}[/tex]
Where: [tex]d_{1}[/tex] and [tex]d_{2}[/tex] are the diagonals.
Given that:
[tex]d_{1}[/tex] = 40 cm = 0.4 m
[tex]d_{2}[/tex] = 25 cm = 0.25 m
Then,
Area of each tile = [tex]\frac{0.4*0.25}{2}[/tex]
= [tex]\frac{0.1}{2}[/tex]
= 0.05 [tex]m^{2}[/tex]
Area of each tile is 0.05 [tex]m^{2}[/tex].
Since there are 2000 tiles on the floor of the building, then;
Total area covered by the tiles = 0.05 x 2000
= 100 [tex]m^{2}[/tex]
The total cost of polishing the floor = 100 x Rs/5
= Rs/500

How long does it take to travel 100km at a speed of 80 km/h?
Answers
You can kind of tell that, because the units of speed is km/h ( or m/s, or miles/hour — depending on the situation).
Now if you apply your algebra skills, you might discover that
time = distance/speed
Plug in the data:
time = 100 km / (80 km/h)
After application of algebra skills again you can see that the units will simplify to simply h.
time = 1.25 h

Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden. Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam. This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears. Which batch of jam tasted more like cranberries?
Answers
Answer:
The batch of jam from this summer
Step-by-step explanation:
Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden.
For last summer
Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam.
Hence,
5 cup of pears = 3 cups of cranberries
1 cup of pears = x
Cross Multiply
5x = 3
x = 3/5
x = 0.6
1 cup of pears = 0.6 cup of cranberries
For this summer
This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears.
Hence,
8 cup of pears = 5 cups of cranberries
1 cup of pears = x
Cross Multiply
8x = 5
x = 5/8
x = 0.625
1 cup of pears = 0.625 cup of cranberries
From the above calculation we can see that the quantity of cranberries to 1 cup of pears from this summer is higher than that of last summer
Therefore, the batch of jam that tasted more like cranberries is the batch of jam from this summer
Answer:
This summer’s batch jam tasted more like cranberries.

A scale factor of 4in to 5in should be used
Step-by-step explanation:
Given
[tex]Original\ Measurement = 4.5\ in[/tex]
[tex]Scale\ Measurement = 3.6\ in[/tex]
Required
Determine the scale to use
The scale to use can be represented as:
[tex]Scale = Scale\ Measurement : Original\ Measurement[/tex]
This gives:
[tex]Scale = 3.6\ in : 4.5\ in[/tex]
Divide by 0.9
[tex]Scale = \frac{3.6}{0.9}\ in : \frac{4.5}{0..9}\ in[/tex]
[tex]Scale = \frac{3.6}{0.9} : \frac{4.5}{0.9}[/tex]
[tex]Scale = 4 : 5[/tex]

The solution x > 10 can be represented in two ways such as:
Interval Notation: (10, ∞)Inequality Notation: x > 10Step-by-step explanation:
Let 'x' be the solution to the inequality
From the given line, it is clear that
x > 10
It means the value of x is greater than 10, which means the solution contains all the positive real numbers greater than 10.
From the number line, it is clear that the number line would include all the numbers on the right-hand side of the 10 number.
The number 10 is not included; thus the number line indicates an open circle on 10, meaning 10 is not include in the solution.
Thus, the solution x > 10 can be represented in two ways such as:
Interval Notation: (10, ∞)Inequality Notation: x > 10Refer to the diagram shown.
