Answer:
Step-by-step explanation:
Find the unit rate of Sugar. Then find the cost of 2.5 Kg sugar
1 kg sugar =36 ÷ 4.5
[tex]= \frac{36*10}{4.5*10}= \frac{360}{45}\\\\= 8[/tex]
2.5 kg of sugar= 2.5 * 8 = 20.0 = R 20
Answer:
Kg Rupee
4.5 = 36
2.5 = ?
Therefore, 2.5*36/4.5
Therefore, 25*36*10/45*10
Therefore, 25*36/45
Therefore, 5*5*36/9*5
Therefore, 5*36/9
Therefore, 5*3*2*3*2/3*3
Therefore, 5*2*2
Therefore, 10*2
Therefore, 20
2.5 kg =20 Rupees

Primary school students are playing hide and seek at recess as the counting begins Jon runs 100 feet east , turns 45 degrees north of east and runs another 120 feet to find a hiding spot . Lisa finds her hiding spot by running 120 feet west , turning 32 degrees south of west , and continuing another 100 feet which students hiding spot is closer to starting point ?
Answer:
Jon's hiding spot is closer to the starting point.
Step-by-step explanation:
Jon's final position forms a triangle with sides 100 ft and 120 ft respectively with an angle of 180 - 45 = 135 between them. Since the angle between the 100 ft direct east and 120 ft direction is 45, since Jon turns 45 after moving for 100 ft and then moves another 120 ft to his final destination.
Also, Lisa's final position forms a triangle with sides 120 ft and 100 ft respectively with an angle of 180 - 32 = 148 between them. Since the angle between the 120 ft direction west and 100 ft direction south of west is 45, since Lisa turns 32 after moving for 120 ft and then moves another 100 ft to her final destination.
Using the cosine rule,
a² = b² + c² - 2abcosФ, we find the length of the third side of each triangle which is their distance from the starting point.
So, for Jon
a² = b² + c² - 2abcosФ where b = 100 ft, c = 120 ft and Ф = 135°
Thus,
a² = (100 ft)² + (120 ft)² - 2(100 ft)(120 ft)cos135°
a² = 10000 ft² + 14400 ft² - 24000 ft²cos135°
a² = 10000 ft² + 14400 ft² - 24000 ft²(-0.7071)
a² = 24400 ft² + 16970.56 ft²
a² = 41370.56 ft²
a = √(41370.56 ft²)
a = 203.4 ft
for Lisa
a'² = b'² + c'² - 2a'b'cosФ' where b = 120 ft, c = 100 ft and Ф = 148°
Thus,
a'² = (120 ft)² + (100 ft)² - 2(120 ft)(100 ft)cos148°
a'² = 14400 ft² + 10000 ft² - 24000 ft²cos148°
a'² = 14400 ft² + 10000 ft² - 24000 ft²(-0.8481)
a'² = 24400 ft² + 20353.15 ft²
a'² = 44753.15 ft²
a' = √(44753.15 ft²)
a' = 211.56 ft
a' ≅ 211.6 ft
Since a = 203.4 ft < a' = 211.6 ft,
Jon's hiding spot is closer to the starting point.

Evaluate the expression
1/5^−3⋅1/5^6
Answer:
The answer is 1 953 125
Step-by-step explanation:
(1/5)^(-3)/(1/5)^6
First, we evaluate the resultant power: (1/5)^(-3)/(1/5)^6=(1/5)^(-3-6)=(1/5)^(-9)
Then, we evaluate the value of the expression: (1/5)^(-9)=5^9=1 953 125
Thus, the answer is 1 953 125

The product of two consecutive square numbers is 900.
Work out the two numbers.
Answer:
25&36
Step-by-step explanation:
25 is a square no and so is 36 and there product is 900. They are also consecutive.
Just assemble the square nos from the least i.e 4 and try solving as asked to see if it gives 900.
Thus u'll land on 25&36

Jim sells hot dogs for $2.95 each and steak sandwiches for $9.95 each out of his food cart. During a busy outdoor festival, he sold a total of 985 items for $7343.75. How ,am steal sandwiches did he sell?
Step-by-step explanation:
x + y = 985
2.95x + 9.95y = 7343.75
-2.95x - 2.95y = -2905.75
7y = 4438
y= 634 steak sandwiches
x + 634 = 985
x = 351 hot dogs
Answer:
634 steak sandwiches
Step-by-step explanation:
h = hot dogs
s = steak sandwiches
First, lets make 2 equations.
2.95h + 9.95s = 7343.75
h + s = 985
We can make the second equation h = 985 - s
Now substitute h into the first equation.
2.95(985 - s) + 9.95s = 7343.75
Distribute the 2.95
2905.75 - 2.95s + 9.95s = 7343.75
Simplify s
2905.75 + 7s = 7343.75
Subtract 2905.75 from both sides
7s = 4438
s = 634
If h = 985 - s and s = 634 we can find h by subtracting 634 from 985
985 - 634 = 351
Now to check:
351 times 2.95 = 1035.45
634 times 9.95 = 6308.3
6308.3 + 1035.45 = 7343.75 so that means our answer is correct.
Hope this helps!!

fraction = 9/32
Decimal = this can be derived by dividing 9 by 32 = 0.28
Percentage = this can be derived by multiplying the decimal by 100 = 28%
Step-by-step explanation:
Number of invitations mailed = 1/3 x (total invitation - invitation mom delivered)
1/3 x (32 - 5)
1/3 x (27)
= 9
This figure can be expressed as a fraction
A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.
The numerator is the number above. While the denominator is the number below
an example of a fraction = [tex]\frac{1}{2}[/tex]
1 is the numerator while 2 is the denominator
fraction = 9/32
Decimal = this can be derived by dividing 9 by 32 = 0.28
Percentage = this can be derived by multiplying the decimal by 100 = 28%

Jill is baking an apple pie. She cuts each apple into rectangular prism pieces and length 1 inch, width 1/4 inch, and height 1/2 inch. In total, she cuts 528 apple slices. What is the volume of each slice? What is the volume of all of the cut apples?
Step-by-step explanation:
Area of Rectangle Prism = Area of base x height
= Length x Width x Height
[tex] = 1 \times \frac{1}{4} \times \frac{1}{2} \\ = 0.125 {in}^{3} [/tex]
One Apple Pie =
[tex]0.125 {in}^{3} [/tex]
Volume of 528 Apple Pies = Volume of 1 apple pie x 528
=
