On solving the provided question, we can say that the inequality provided is -s < 6 he values that stratifies will be = 0-6
What is inequality?An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

in a savings account earning 4.25%
simple interest per year.
How much interest will Bianca earn for a period of 3
years?
Bianca will earn interest of $382.5 for a period of 3years.
What is simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same.
Simple interest is calculated with the following formula:
S.I. = P × R × T,
where P = Principal, R = Rate of Interest in % per annum, and T = Time
Given,
Principal P = $3000
Rate of interest R = 4.25% = 4.25/100 = 0.0425
Time T = 3 years
Simple interest S.I. = P × R × T
= 3000 × 0.0425 × 3
= 127.5 × 3
S.I. = $382.5
Hence, Interest Bianca will earn in 3 years = $382.5

3, 3/4, 3/16 find the 6th term
The sixth term is [tex]\frac{3}{1024}[/tex] .
Given series : 3, [tex]\frac{3}{4}[/tex] , [tex]\frac{3}{16}[/tex] and so on.
We need to find the sixth term, so n = 6.
The given series is in Geometric Progression.
To find the [tex]n^{th}[/tex] term of a Geometric Progression,
[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]
a is the first term of any series. Here, a = 3
r is common ratio. Here, r = [tex]\frac{1}{4}[/tex]
According to the question,
[tex]a_{6}[/tex] = 3[tex](\frac{1}{4} )^{6-1}[/tex]
⇒ [tex]a_{6}[/tex] = 3 × [tex](\frac{1}{4} )^{5}[/tex]
⇒ [tex]a_{6}[/tex] = 3 × [tex]\frac{1}{1024}[/tex]
⇒ [tex]a_{6}[/tex] = [tex]\frac{3}{1024}[/tex]
So, the sixth term is [tex]\frac{3}{1024}[/tex].
Dr. Goldsman is buying fertilizer for his lawn. - Xtra Green covers 1/20 of an acre with 1/2 of a pound of fertilizer granules. - Best Lawn covers 1/15 of an acre with 1/5 of a pound of fertilizer granules. If Dr. Goldsman wants to buy the brand that covers the most area per pound, which brand should he buy?
The Best Lawn covers the most area per pound is better choice to buy.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Xtra Green covers 1/20 of an acre with 1/2 of a pound of fertilizer granules.
So, area per pound covered by Xtra Green
= (1/20) /(1/2)
= 1/20 x 2/1
= 1/10
= 0.1
Best Lawn covers 1/15 of an acre with 1/5 of a pound of fertilizer granules.
So, area per pound covered by Best Lawn
= (1/15) /(1/5)
= 1/15 x 5/1
= 1/3
= 0.333
Hence, Best cover larger Area is better choice.

If 1st number is a series of consecutive odd numbers is 6 less than the last one in the series, how many numbers are there is the series.
Let's call the first number in the series "x", and the last number in the series "y".
We know that the series is a consecutive series of odd numbers, and we also know that y is 6 less than the last number in the series.
Since the series is a consecutive series of odd numbers, we can say that the difference between any two consecutive numbers in the series is 2.
So, we can write an equation to represent this information:
y = x + (n-1) * 2
where n is the number of numbers in the series.
We also know that y is 6 less than the last number in the series, so we can add this information to our equation:
y = x + (n-1) * 2 - 6
To solve for n, we can rearrange the equation:
n = (y - x + 6) / 2 + 1
Now, if we know the value of x and y we can substitute them in the equation and find the number of terms in the series.

a) The amount of money that Tony invested is; £1350
b) The rate of compound interest is; 4%
c) The graph that represents the growth in Toni's account is; Graph C
How to find the compound interest?The formula for the total value of her investment after t years is given by the formula; v = 1350 * 1.04^t
The general formula used to calculate the interest rate is given by,
a = p * (1 + r)^t
where;
a is amount
p is principal
r is rate of interest
t is time period
Comparing the given equation with standard equation, we have;
a = v
p = 1350
t = t
Now, 1 + r = 1.04
1 + r = 1 + 0.04

when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as h ( t )
Now , the equation will be
h ( t ) = -16t² + 64t + 80 be equation (1)
a)
The number of seconds for the baseball to reach the ground be t
The height when the ball reaches the ground will be h = 0
Substituting the value of h ( t ) = 0 , we get
0 = -16t² + 64t + 80
On simplifying the equation , we get
16t² - 64t - 80 = 0
Divide by 16 on both sides of the equation , we get
t² - 4t - 5 = 0
On factorizing the equation , we get
t² + t -5t - 5 = 0
t ( t + 1 ) - 5 ( t + 1 ) = 0
( t - 5 ) ( t + 1 ) = 0
The value of t is time and it is not negative
So , when ( t - 5 ) = 0
Adding 5 on both sides of the equation , we get
t = 5 seconds
b)
The number of seconds the baseball to reach the maximum height be T
And graph of the function is a parabola open down because the leading coefficient is negative. Therefore, to get the maximum height we just have to find the vertex of this parabola
T = ( -b / 2a )
On simplifying the equation , we get
T = ( -64 / ( 2 ( 16 )
T = -64 / 32
T = 2 seconds
c)
The maximum height of the baseball is when T = 2
Substituting the value of t = 2 in the equation , we get
h ( t ) = -16t² + 64t + 80
h ( 2 ) = -16 ( 2 )² + 64 ( 2 ) + 80
On simplifying the equation , we get
h ( 2 ) = -64 + 128 + 80
h ( 2 ) = 64 + 80
h ( 2 ) = 144 feet
Hence , the equation is solved

how many total wholes are in 7/3.
Answer:
The fraction 7/3 cannot be expressed as a whole number. The fraction 7/3 can be expressed as a decimal, which is 2.3333.... and goes on forever, or as a mixed number, which would be 2 and 1/3.
It's important to note that when dividing two integers, the result is not guaranteed to be a whole number.
