Answer:
28 < x < 114
Step-by-step explanation:
x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well43 + x > 71 Subtract 43 from both sides.43-43 + x > 71 - 43x > 28To put this in the form of the answer you need it looks like this.28 < x < 114Related Questions

sally's soccer team played 25 games and won 17 of them. what percent did the team win? please leave an step by step explanation.
Answers
The Percentage of Sally's Team Wins :
[tex]\bf{\implies (\frac{Number\;of\;Games\;won\;by\;the\;Team}{Total\;Number\;of\;Games\;the\;Team\;Played}) \times 100}[/tex]
Given : Total Number of Games the Team Played = 25
Given : Number of Games won by the Team = 17
[tex]\bf{The\;Percentage\;of\;Team\;Wins = (\frac{17}{25}) \times 100}[/tex]
⇒ The Percentage of Sally's Team Wins = (17 × 4) = 68%
Sally's soccer team played 25 games and the team won 17 games. What percent of games did the team win?
The fraction [tex]\frac{17}{25}[/tex] represents the number of games that Sally's soccer team won out of all the games the team played.
To find what percent of games the team won, we can turn the fraction [tex]\frac{17}{25}[/tex] into a percent.
17 ÷ 25 = 0.68
0.68 × 100 = 68%
Therefore, Sally's soccer team won 68% of the games they played.

x-3 = 49
Answer: C) x - 3 = 49
Step-by-step explanation: X represents the number that we are subtracting things from. 3 is how much (the number that we are) subtracting. 49 is the difference/answer. The problem is pretty much asking us to subtract 3 from x and get 49 as the answer. So, if you wrote that mathematically, the answer would be x - 3 = 49.

B 1/5
C 5/8
D 23/40
Answers
Answer:
A. 33/56
Step-by-step explanation:
Make them have the same denominator of 56
so you get for the first one 49/56
the second one will be 16/56
subtract both and you get your answer of 33/56
Answer: A. 33/56
Step-by-step explanation:
To get the number of pages left, all we need to do is to subtract 2/7 from 7/8
number of pages left = 7/8 - 2/7
=49 - 16 / 56
= 33/56

Select Independent or Not independent for each description of events.
P(A)=0.3, P(B)=0.5, P(A|B)=0.15
P(A)=0.2, P(B)=0.4, P(A|B)=0.2
P(A)=0.6, P(B)=0.2, P(A|B)=0.3
Answers
Answer:
When two events X and Y are independent,
Then, P(X ∩ Y) = P(X) × P(Y)
We know that,
[tex]P(\frac{X}{Y})=\frac{P(X\cap Y)}{P(Y)}\text{ and }P(\frac{Y}{X})=\frac{P(X\cap Y)}{P(X)}[/tex]
Thus, by substituting the value of P(X ∩ Y),
[tex]P(\frac{X}{Y})=P(X)\text{ and }P(\frac{Y}{X})=P(Y)[/tex]
Which is the required condition for independent events.
In first option,
P(A)=0.3, P(B)=0.5, P(A|B)=0.15
[tex]\implies P(\frac{A}{B})\neq P(A)[/tex]
⇒ A and B are not independent events
In second option,
P(A)=0.2, P(B)=0.4, P(A|B)=0.2
[tex]P(\frac{A}{B})=P(A)[/tex]
⇒ A and B are independent events.
In third option,
P(A)=0.6, P(B)=0.2, P(A|B)=0.3
[tex]\implies P(\frac{A}{B})\neq P(A)[/tex]
⇒ A and B are not independent events
First Part: Not independent
Second Part: Independent
Third Part: Not independent
Two events A and B are independent if:
[tex]P(A|B)=P(A|B') \\Or,P(B|A)=P(B|A')[/tex]
Given,
[tex]P(A)=0.3, P(B)=0.5, P(A|B)=0.15[/tex]
[tex]P(A)=0.2, P(B)=0.4, P(A|B)=0.2[/tex]
[tex]P(A)=0.6, P(B)=0.2, P(A|B)=0.3[/tex]
[tex]P(A\cap B)=P(A|B)P(B)[/tex]
Then by substituting we get,
[tex]P(A|B)=P(A)[/tex] and [tex]P(B|A)=P(B)[/tex]
Computation of First probability:
So, if the probability is independent it will follow the above conditions.
[tex]P(A|B)=0.15\\P(A)=0.3\\0.3\neq 0.15\\ P(A|B)\neq P(A)[/tex]
So, it is not independent
Computation of second probability:
So, if the probability is independent it will follow the above conditions.[tex]P(A|B)=0.2\\P(A)=0.2\\0.2=0.2\\ P(A|B)= P(A)[/tex]
So, it is independent
Computation of second probability:
So, if the probability is independent it will follow the above conditions.
[tex]P(A|B)=0.3\\P(A)=0.6\\0.3\neq 0.6\\ P(A|B)\neq P(A)[/tex]
So, it is not independent.

Answer:
We will need 5 1/3 lbs of hamburger
Step-by-step explanation:
We can use ratio's to solve this problem. We will put breadcrumbs on top and hamburger on bottom.
1/4 c 1 1/3 c
--------- = -----------
1 lb x lbs
Using cross products
1/4 *x = 1 * 1 1/3
1/4x = 1 1/3
Multiply each side by 4
4 * 1/4 x = 4 * (1 1/3)
x = 4 * 1 1/3
We need to convert 1 1/3 to an improper fraction
1 1/3 = (3*1+1)/3 = 4/3
x = 4 * 4/3
x = 16/3
Now we need to convert it back to a mixed number
3 goes into 16 5 times with 1 left over
x = 5 1/3 lbs
What is the foil method of (X+3)(x-4)
Answers
Answer:
(x-1) x-12
Step-by-step explanation:
Step 1 : Multiply first term of the first bracket to the first term of the other bracket
Step 2 : Then multiply the first term of the first bracket to the last term of the second bracket.
Step 3 : Now come to the second term of first bracket, multiply second term with first term of second bracket.
Step 4 : Finally multiply last term of first bracket with the last term of the second bracket.
Step 5 : Adding all the answers got from the steps, we get the final answer.
Final answer:
The FOIL method is an algebraic technique for multiplying two binomials, represented as (First, Outer, Inner, Last). For the expression (X+3)(x-4), we apply this method to get x^2 - x - 12 after combining like terms.
Explanation:
The FOIL method is a technique used in algebra to multiply two binomials. The acronym FOIL stands for First, Outer, Inner, Last and refers to the order in which you multiply the terms in the binomials. Applying the FOIL method to the expression (X+3)(x-4), we multiply the First terms (x × x), the Outer terms (x × -4), the Inner terms (3 × x), and the Last terms (3 × -4), then sum them all.
Step-by-step, this looks like:
First: x × x = x^2
Outer: x × (-4) = -4x
Inner: 3 × x = 3x
Last: 3 × (-4) = -12
Now, combine these results to get the final expression:
x^2 - 4x + 3x - 12
Combining like terms, we have:
x^2 - x - 12

A circle has a radius of r inches. The area of a circle is represented by the expression
[tex]3.14 {r}^{2} [/tex]The area of a circle is a function of the radius. Does this situation represent a linear or nonlinear function? Explain
Answers
Answer: Nonlinear
Step-by-step explanation: If the exponent is to a power other than 1, it is nonlinnear.
The area of a circle, represented by the expression 3.14r², is a nonlinear function because the area changes in proportion to the square of the radius, demonstrating a quadratic change rather than a linear one.
The area of a circle is a function of the radius, represented by the expression 3.14r². This represents a nonlinear function because the area of the circle does not change at a constant rate with respect to the radius. Instead, the area changes in proportion to the square of the radius, which is a defining characteristic of a quadratic or second-degree polynomial function, not a linear one.
To further illustrate, let's consider a circle with a radius of 1 inch, which would have an area of approximately 3.14 square inches. If the radius is doubled to 2 inches, the area becomes approximately 4 times larger, not double, because the area is 3.14 * (2²) = 3.14 * 4 square inches. This quadratic change demonstrates the nonlinearity of the area function in relation to the radius.

Hope this helped!
Answer:
option C (3, 2)
Step-by-step explanation:
We have to solve the system of equation by substitution method.
2x + y = 8 ------(1)
y = -x + 5 -------(2)
Now we substitute the value of y from equation (2) to equation (1)
2x + ( -x + 5) = 8
2x - x + 5 = 8
x + 5 = 8
x = 8 - 5
x = 3
Now from equation (2)
y = -x + 5
y = - 3 + 5
y = 2
Therefore, option C (3, 2) will be the answer.
