ashley recently opened a store that uses only natural ingredients. she wants to advertise her products by distributing bags of samples in her neighborhood. it takes one person 2/3 of a minute to prepare one bag.
Ashley and her four friends will need 5 hours and 19.57 minutes to make 1575 bags if Ashley takes 2/3 of a minute and each friend takes 75% longer.
What is a minute?
The first sexagesimal fraction of an hour, or one-fifth of an hour, or 60 seconds, is known as the minute. On rare occasions, due to leap seconds, a minute in the UTC time zone has 61 seconds (A negative leap second might be inserted, producing a minute of 59 seconds; however, this has never occurred in more than 40 years under this system.) The minute can be used with SI units even if it isn't a SI unit. Minute or minutes is represented by the SI unit min (without a dot). Occasionally, people would slangy refer to minutes of time by the prime symbol.
Calculations:
For a bag, Ashley needs about 2/3 of a minute.
= Ashley prepare bag in 1 minute = 3/2
Her friends takes 75% Longer to prepare a bag
time taken by her friends = 2/3 + (75/100)(2/3)
= (2/3)( 1 + 3/4)
= (2/3)(7/4)
= 7/6 Minutes
Her one friend prepare bag in 1 minute = 6/7
Bag prepared by Ashley & her 4 friend in 1 Minute
= 3/2 + 4*6/7
= (21 + 48)/14
= 69/14 Bag
69/14 Bag prepared in 1 minute
1 Bag prepared in 14/69 minutes
1575 bags prepared in 1575 * 14/69
= 319.57 minutes
= 5 hrs 19.57 Minutes

The best term that describes the number of solutions that will maximize the function is one optimal solution (a).
Number of Solutions in linear equations:
There are 3 possible types of solutions to the set of linear equations. They are:
Unique Solution - linear equation represents that there exists only one point, which on substitution, L.H.S becomes equal to R.H.S. In the case of simultaneous linear equations in two variables, the solution should be an ordered pair (x, y).
No Solution - linear equations are parallel, then the system of linear equations has no solution.
Infinitely Many Solutions - graph for the system of linear equations with infinitely many solutions is a graph of straight lines that overlaps each other.
Given,
Here we need to find the number of solutions that will maximize the function below given the constraints listed.

Find the dimensions of a rectangle if the perimeter is 318 inches and the
length is half the width plus nine inches.
The dimensions of the rectangle are 59 by 50 inches
How to fnd the dimensions of a rectangle?The given parameters are
Length (l) = 1/2 width (w) + 9
Perimeter (P) = 318
Perimeter is calculated as
P = 2 (l + w)
Substitute l = 1/2w + 9 in P = 2(l + w)
So, we have
2 * (1/2w + w + 9) = 318
Evaluate the like terms
2 * (1.5w + 9) = 318
Divide by 2
1.5w + 9 = 159
So, we have
1.5w = 150
Divide by 15
w = 100
Substitute w = 100 in l = 1/2w + 9
l = 1/2 * 100 + 9
Evaluate
l = 59

A circular table top has a radius of 90 cm. A force of 810 N is applied to the whole table top. Calculate the pressure in N/m2 to 4sf.
The pressure of the circular table top has a radius of 90 cm. A force of 810 N is applied to the whole table top = 287.23 N/m².
The force defined as:A force seems to be an influence that could also cause an object's motion to change. A force can cause a mass item's velocity or acceleration to alter. The force can be expressed intuitively as a push or perhaps a pull. Because it has both magnitude and direction a force is a vector quantity.
What exactly do you mean by pressure?The force applied against the surface of an item per unit area across which that force is spread is referred to as pressure (symbol: p or P).
According to the given data:Force = 810N
Radius of the circular table = 90cm.
Pressures = force /area
Finding the area of circular table = πr²
= π x 90 x 10⁻² (1 cm = 10⁻²)
= 2.82 m²
substituting the value in the formula.
Pressures = force /area
= 810/2.82
= 287.23 N/m²
The pressure of the circular table top has a radius of 90 cm. A force of 810 N is applied to the whole table top = 287.23 N/m²

two and half of a number added to three quarters of the same number gives you 13.find the number.
Answer:
52/21
Step-by-step explanation:
Translate the word equation into an algebraic equation as follows:
Let the number be X
two-and-a-half of a number --> (2 1/2) X
2 1/2 = (2 x 2 + 1) = 5/2
So two-and-a-half of a number --> (9/2)X = 9X/2
three-quarters of the same number --> (3/4)X --> 3X/4
two and half of a number added to three quarters of the same number becomes 9X/2 + 3X/4
gives you 13 --> = 13
So we get the equation:
9X/2 + 3X/4 = 13
Multiply both sides by 4 to get rid of the denominators
4.(9X/2) + 4(3X/4) = 4 x 13 = 52
36X/2 + 12X/4 = 52
==> 18X + 3X = 52
==> 21X = 52
==> X = 52/21

A contaminat is found in solution at a level of 3/500%. What fraction of the solution isnthis?
The fraction of the solution present in the contaminant is 3/5.
What is defined by the term fraction?Fractions represent parts of a whole or group of objects. A fraction is made up of two parts. The number at the top of the line is made reference to as the numerator. It specifies the number of equal portions of the entire or collection that are taken. The denominator is the number just below line. It displays the total number of equal portions into which the whole is divided or the total number of identical objects in a collection.First, we convert 50% to fractions.
Changing a percentage to a fraction is equivalent to dividing a number by 100.
500% = 500/100
Taking this into account, we get 3/(500/100).
Then, when we divide a number by a fraction, we multiply the result by the inverse of the fraction.
= 3/(500/100)
= 3 x 100/500
Further simplifying;
= 300/500
= 3/5
Therefore, the value of the fraction of contaminant solution is 3/5.

Work Shown:
A = 18 take bio
B = 13 take Spanish
C = 5 take both
A+B-C = 18+13 - 5 = 26 students total

Another approach:
18 take bio and 5 take both, so 18-5 = 13 take bio only
13 take Spanish and 5 take both, so 13-5 = 8 take Spanish only
We then have 13+8+5 = 26 students
Both methods only work when each student is in either bio, Spanish, or both. We cannot have a student who is in neither class.
