Answer:
Step-by-step explanation:
There are two restrictions on x: First, x must be less than -4; second, x must be greater than 5. Both of these inequalities have an infinite number of solutions, so overall this set of restrictions has an infinite number of solutions.

Finally, she treated her friend to lunch with some of the remaining money. After lunch, Bonnie had $300.50 left. How much money did Bonnie spend on lunch?
Bonnie spent $______on lunch.
Answer:
the answer is 19.50
Step-by-step explanation:
lets start by by reviewing the problem
bonnie withdrew 1200 dollars
she spend 240 on travel agents
then she spends 640 at the hardware store
so if we add all of that up we get 880
then we will subtract that from the total of her money
=320 left but we aren't finished
then she spend some money on lunch
so we would subtract 320 from
300.50

A person's batting average is determined by dividing the number of hits by the
number of at bats. William has 11 hits in 53 at bats and has a batting average of
0.208. He wants to have a batting average of at least 0.300.
Which equation could be used to determine x, the number of hits in a row William
needs to get in order to have a batting average of at least 0.300?
11x
A. 0.300 s
53x
11
B. 0.300x s
53
11 + x
C. 0.300 s.
53
11 + x
D. 0.300 s
53 + x
The equation that could be used to determine x is [tex]\frac{11+x}{53+x} \leq 0.300[/tex].
What is inequality?Inequality is a relation that makes a non-equal comparison between two expressions.
Batting average of William = 11/53
Desired batting average = 0.300
Suppose the number of more hits in a row to have desired batting average =x
Number of hits now =11+x
Number of bats now =53+x
It is given that the batting average should be a minimum of 0.300.
This means [tex]\frac{11+x}{53+x} \leq 0.300[/tex]
Therefore, the equation that could be used to determine x is [tex]\frac{11+x}{53+x} \leq 0.300[/tex].

Find the measure of line segment TR
Answer:
17
Step-by-step explanation:
Answer:
TR = 24 units
Step-by-step explanation:
Given 2 secants from an external point to a circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and whole of the other secant, that is
3x(3x + 5x) = 8(8 + 19)
3x × 8x = 8 × 27
24x² = 216 ( divide both sides by 24 )
x² = 9 ( take the square root of both sides )
x = ± [tex]\sqrt{9}[/tex] = ± 3
but x > 0, thus x = 3
Thus
TR = 8x = 8 × 3 = 24

(4) Madison invested $5,000 at a rate of 7.5%. How much money did she have after 6 months?
Answer:
A = $5,187.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7.5%/100 = 0.075 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 5000(1 + (0.075 × 0.5)) = 5187.5
A = $5,187.50
The total amount accrued, principal plus interest, from simple interest on a principal of $5,000.00 at a rate of 7.5% per year for 0.5 years (6 months) is $5,187.50.
The amount of money she saved after 6 months is $5,187.50.
What is Percentage?Chance formula is used to find the quantum or share of commodity in terms of 100. In its simplest form, percent means per hundred. To express a number between zero and one, chance formula is used. It's defined as a number represented as a bit of 100. It's denoted by the symbol, and is majorly used to compare and find out rates.
Given:
r = R/100
r = 7.5%/100
r = 0.075 per year.
Time = 6 months.
= 6/12 = 1/2 year
So, Amount = 5000(1 + (0.075 × 0.5))
A = $5,187.50
The total amount accrued, principal plus interest is $5,187.50.

The first three terms of an arithmetic sequence are as follows 9,4,-1 find the next two terms
The following two terms of an arithmetic progression are -6 and -11.
What is an arithmetic sequence?
An arithmetic sequence is defined as a progression of numbers such that the difference between successive terms is consistent. It is also called Arithmetic Progression. The formula for tthe last term of an AP is given as: an = a + (n-1)d, here, a is the first term, n is the number of terms and d is the difference between two successive terms.
Finding the two terms of an arithmetic sequence
The first three terms of an arithmetic sequence are given by:
a1 = 9
a2 = 4
a3 = -1
Now, we want to calculate a4 and a5
Using the formula for calculating the next term of an arithmetic progression, we get,
a4 = a + (n-1)d, where n = 4 and d = 5
a4 = 9 + (4-1)(-5)
a4 = 9 - 15
a4 = -6
Further, a5 = a + (n-1)d, where n = 5 and d = 5
a5 = 9 + (5-1)(-5)
a5 = 9 - 20
a5 = -11
Hence, the next two terms of an AP are -6 and -11.

Answer:
12%
Step-by-step explanation:
Add each number of students in the graph together. 1 + 6 + 2 + 3 = 12, so it's 12%.
Percentage of students who responded to the survey is 48 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The total number of students in the survey = 25 students
The number of students who played Violin = 1 student
The number of students who played Piano = 6 students
The number of students who played Guitar = 2 students
The number of students who played Drums = 3 students
So ,
Total number of students who played instruments =
Number of students who played Violin + Number of students who played Piano + Number of students who played Guitar + Number of students who played Drums
Total number of students who played instruments = ( 1 + 6 + 2 + 3 )
= 12 students
Now ,
Percentage of students who played the instruments = Percentage of students who responded to the survey
And ,
Percentage of students who responded to the survey =
( Total number of students who played instruments / Total number of students in the survey ) x 100
Percentage of students who responded to the survey = ( 12 / 25 ) x 100
= 12 x 4
= 48 %
Therefore , percentage of students who responded to the survey = 48 %
Hence , percentage of students who responded to the survey is 48 %
