Rachel bought 6 1/4 pounds of dried fruit. If 1/3 of the fruit was dried apricots, how many pounds of dried apricots did she buy?
Rachel bought 6 1/4 pounds of dried fruit. If 1/3 of the fruit was dried apricots, then the pounds of dried apricots which she bought was 25/12 or 2.08pounds.
What is Arithmetic operation?This basically comprises of operations such as Addition, Subtraction, Multiplication and Division.
Operations such as 'of ' are usually represented with the multiplication sign which is ( × ). In this scenario we were told that 1/3 of the 6 1/4 pounds of dried fruit was dried apricot.
This therefore means that 1/3 of 25/4 = 1/3 × 25/4 = 25/12.
This means that 25/12 or 2.08pounds was bought by her.

Consider a civilization broadcasting a signal with a power of 2.0×104 watts. The Arecibo radio telescope, which is about 300 meters in diameter, could detect this signal if it is coming from as far away as 141 light-years. Suppose instead that the signal is being broadcast from the other side of the Milky Way Galaxy, about 70000 light-years away.
For light: Inverse Square Law
The signal is weaken by the inverse square of the
difference of distances this means that one over the square of the
difference.
Therefore, 70000LY / 141 LY =496.45 and that squared =246462.602 times less signal, or 1/246462.602.
2 For a circular telescope like the
Arecibo radio telescope that equals Pi times the radius squared. Sensitivity
of the telescope depends on its area.
The new telescope needs 246462.60 times that area to have
enough sensitivity
(150 x 150 x Pi) = 70 685 sq m area for the Arecibo telescope
and that times 246462.60
= 1.74212 x 10^10
What is the diameter of a circle with that area?
1. Divide the area by Pi = 5.548156 x 10^9
2. Take the square root of the result to find the radius = 74485.94293
3. Multiply by 2 to find the diameter = 148971.886

A city ordinance in River City requires that there be a police officer for every 470 residents. If the population of River city is 410,300, what is the minimum number of police officers needed?
To meet the city ordinance's requirement, River City needs at least 874 police officers, determined by dividing the population of 410,300 by 470 and rounding up to the nearest whole number.
To determine the minimum number of police officers needed for the population of River City, we simply divide the city's population by the number of residents per officer as required by the ordinance. In this case, we divide 410,300 residents by the ordinance's requirement of one officer for every 470 residents.
Calculation: 410,300 residents / 470 residents per officer = approximately 873.19.
Since we cannot have a fraction of a police officer, we round up the number to the nearest whole number to ensure that we meet the minimum requirement. Therefore, River City needs at least 874 police officers.
Simplify.

Solve this problem in your notebook using all four steps. Harvey is 3 times as old as Jane. The sum of their ages is 48 years. Find the age of each. Jane is _____ a0 years old. Harvey is ____ a1 years old.
Answer:
Jane is 12 and Harvey is 36
Step-by-step explanation:
Answer: The jane is 12 years old and Harvey is 36 years old.
Explanation:
Let jane's age is defined by J and Harvey's age is defined by H.
It is given that the Harvey is 3 times as old as Jane. It means the age of Harvey is 3 times of the age of jane.
H = 3J ..... (1)
It also given that the sum their ages is 48.
H + J = 48 ..... (2)
Using equation (1), Put H = 3J,
3J + J =48
4J = 48
J = 12
Substitute this value is equation (1).
H = 3(12)
H = 36
Therefore, the Jane's age is 12 and the Harvey's age is 36.

To estimate the product or quotient, round numbers to the nearest whole or compatible number: 5 multiplied by 2 3/5 is about 15; 25 7/8 divided by 2 8/9 is about 9; and the total pizzas eaten by all classes is about 11.
Estimation with Rounding and Compatible Numbers
The estimation of products or quotients using rounding or compatible numbers involves adjusting values to simpler, more manageable numbers before performing the calculation. Here's how to estimate each of the provided examples:
For estimating the product of 5 by 2 3/5, you can round 2 3/5 to 3, which is a compatible number since 5 times 3 equals 15. Hence, the estimated product is about 15.To estimate the quotient of 25 7/8 divided by 2 8/9, round 25 7/8 to 26 (as 7/8 is close to a whole) and 2 8/9 to 3 (since 8/9 is close to 1), resulting in an estimated quotient of about 9 when you divide 26 by 3.For the total pizzas eaten by all three classes, use benchmarks: 3 2/3 rounds to 4, 4 1/8 rounds to 4, and 3 1/4 rounds to 3. Adding these gives 4+4+3 which equals 11. So, the total estimated number of pizzas is about 11.These estimations use the concept of rounding to the nearest whole number or to a fractions compatibility and demonstrate the importance of not over-representing the precision in your answer. Moreover, estimations are especially useful in mental math and when an approximate answer is sufficient.
