Answer:
The positive solution to the nearest tenth is (2.4, - 0.2).Explanation:
I will rewrite the table to understand how the process of solving using succesive approximations is.
Table:
x f(x) g(x)
0 - 5 - 6
1 - 3 - 5
2 - 1 - 2
3 1 3
Those are the points shown in the table.
Now you must continue the process of solving using successive approximations until you find the positive solution to the nearest tenth.
You need to determine whether a "guess" is closer or farther away of the solution.
The first row shows that g(x) is less than f(x) in 1 unit when x = 0 ( -6 - (-5) ) = -1.
The second raw shows that g(x) is less than g(x) in 2 units when x = 1 ( - 5 - (-3) ) = - 2
The third row shows that g(x) is is less than f(x) in 1 unit when x = 2 ( - 2 - (-1) ) = - 1.
The fourth row shows that g(x) is than f(x) in 2 units when x = 3 ( 3 - 1 = 2).
Hence, the trend changed form negative to positive, meaning that, since the functions are continous, there must be an intertemediate value of x (between x = 2 and x = 3) for which f(x) = g(x) and that is the solution.
Therefore, test x = 2.5
f(x) = 2x - 5 = 2(2.5) - 5 = 0g(x) = x² - 6 = (2.5)² - 6 = 0.25g(x) - f(x) = 0.25 Thus the difference is bigger than one tenth (0.1)Test for x = 2.4
f(2.4) = 2(2.4) - 5 = - 0.2g(2.4) = 2.4² - 6 = -0.24g(2.4) - f(2.4) = - 0.24 - (0.2) = -0.04Now the difference is less than 0.1 and the solution to the nearest tenth is (2.4, - 0.2).

Harper went into a movie theater and bought 10 bags of popcorn and 6 drinks,
costing a total of $79. Damian went into the same movie theater and bought 3 bags of
popcorn and 5 drinks, costing a total of $36.50. Write a system of equations that
could be used to determine the price of each bag of popcorn and the price of each
drink. Define the variables that you use to write the system.
Answer:
The price of a drink = $4
The price of a bag of popcorn = $5.5
Step-by-step explanation:
Let p represent popcorn and d represent drink
Harper bought 10 bags of popcorn and 6 drinks and paid $79 ➡ 10p + 6d = $79
Damian bought 3 bags of popcorn and 5 drinks and paid $36.50 ➡ 3p + 5d = $36.50
Now multiply first equation by -3 and second equation by 10
-3 × (10p + 6d) = $79 ➡ -30p - 18d = -$237
10 × (3p + 5d) = $36.50 ➡ 30p + 50d = $365
Now add the new equationd
30p + 50d -30p - 18d = $365 - $237 (-30p will eliminate 30p)
32d = $128 divide both sides of the equation by 32
32 ÷ 32d = 32 ÷ $128 ➡ d = 4
If d = 4 that means a drink costs $4 we can use this information to find the price of a bag of popcorn
3p + 5d = $36.50 (replace d with 4)
3p + 4×5 = $36.50
3p + 20 = $36.50
3p = $36.50 - 20
3p = 16.50 divide both sides by 3
p = $5.5
The question asked to set up a system of equations to determine the price of each bag of popcorn and each drink. Using the variables x and y to represent the price of popcorn and drinks respectively, the system of equations based on the information given is 10x + 6y = $79 and 3x + 5y = $36.50.
Explanation:To solve this problem, we need to setup a series of equations based on the information given. Let's say:
x is the price of each bag of popcorny is the price of each drinkAccording to the first scenario with Harper, we get:
10x + 6y = $79
From Damian's shopping, we have:
3x + 5y = $36.50
This gives us the system of equations which can be used to find individual prices of a bag of popcorn and a drink.

A fence is to be built to enclose a rectangular area of 450 square feet. The fence along three sides is to be made of a material that costs $3 per foot. The material for the fourth side costs $9 per foot. Find the dimensions of the rectangle that will allow for the most economical fence to be built.
Answer: 25 by 50 ft
Hope this helps
The dimensions of the rectangle will allow for the most economical fence to be built are 30 feet by 15 feet
Given that, rectangular area=450 square feet.
What is the formula to find the area of a rectangle?The formula to find the area of a rectangle is Area=Length×Breadth.
Let the length of the rectangle be x and the breadth of the rectangle be y.
Now, 450=xy.
x=450/y
The cost of three sides is $3 per foot.
That is, 3x+3x+3y
The cost on the fourth side is $9 per foot.
That is, 9y
Total cost=6x+12y
Now, Total cost=6×450/y+18y
Let the minimum cost be 0.
2700/y+12y=0
⇒2700/y²-12=0
⇒12y²=2700
⇒y=15 feet
So, 450/15=x=30 feet.
Therefore, the dimensions of the rectangle are 30 feet by 15 feet.

A rectangle has side lenghs X +2 and 3X -1 write an expression that represents the perimeter of the rectangle then simplify the expression
Answer: Perimeter = 2(L + W) and
as a simplified expression is, 8x + 2
Step-by-step explanation: The length is represented by L and the width is represented by W in the expression above.
However, since we have been given the sides of the rectangle as x + 2 and 3x - 1, we shall substitute for the values of these in the expression representing the perimeter.
2(L + W) can now be written as
2( {x + 2} + {3x - 1} )
2(x + 2 + 3x - 1)
By collecting like terms, we now have
2(4x + 1)
8x + 2.
The expression can now be simplified as 8x + 2
A straight slide in a playground design makes an isosceles triangle with the
ground and its platform, with area 32 square feet. What is the length of the slide?
A 412 feet 32 © 8/2 feet 126
B 8 feet 6
0 16 feet 256
Answer:
Option D.
Step-by-step explanation:
First, the you need ti understand that the triangle is an isosceles right angled triangle. In other words, the base and height are equal in length. The third side is the slide. This is the longest side. Next, we know that the formula for calculating the area of a right angled triangle is given by:A = 1/2 (base × perpendicular height)
The perpendicular height is equal to the base. Let's say the base is x. It means that the height is also x, since height = base. Therefore, the formula will be:A = 1/2 (x.x)
=1/2 (x²)
32 = 1/2 (x²)
Multiplying both sides by 2 gives:
32×2 = x²
64 = x²
8 = x
To find the third side, we use the Pythagoras theorem:
C² = A² + B²
= 8² + 8²
= 128
C = √128
= 8√2
However, the answer will not be exact, so we multiply the length of the base and height by 2. This gives x = 16 (Length of base = length of height)
Repeating the steps above gives C = √ (16)² + (16)²
= √256
This corresponds to option D.

A card is drawn at random from a pack of 52 playing cards. Given that the card is a diamond, find the probability that the card is a King. Give your answer as a fraction in its simplest form.
================================================
Explanation:
Focus only on the diamond cards. There are 13 of them total. Out of the 13 diamond cards, there is one king of diamonds. So the probability of getting a king, if we know 100% the card is a diamond, is 1/13.
---------------
You can use a slightly longer method through a conditional probability
A = card is a king
B = card is a diamond
P(A and B) = probability of king and diamonds = 1/52
P(A \ B) = probability of event A happens given we know B happens
P(A \ B) = P(A and B)/P(B)
P(A \ B) = (1/52)/(13/52)
P(A \ B) = (1/52) ÷ (13/52)
P(A \ B) = (1/52) * (52/13)
P(A \ B) = 1/13
The probability that the card is a King is 1/13
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given that a card is drawn at random from a pack of 52 playing cards, the total outcome is 52
If the card is a king, the expected outcome is 4
Pr(selecting a king) = 4/52 = 1/13
Hence the probability that the card is a King is 1/13

What is d,the common difference,in the arithmetic sequence 100,98,96,94,92...?
Answer: he is right the answer is -2
Step-by-step explanation:
The common difference (d) is -2.
In an arithmetic sequence, the common difference (d) is the constant value by which each term differs from the previous term.
To find the common difference in the sequence 100, 98, 96, 94, 92..., we can observe the difference between consecutive terms:
98 - 100 = -2
96 - 98 = -2
94 - 96 = -2
92 - 94 = -2
We see that each term is decreasing by 2. Therefore, the common difference (d) is -2.

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule. A(n)=5+(n-1)(1/6)
Answer:
First term: A(1) = 5
Fourth term: A(4) = 5 1/2
Tenth term: A (10) = 6 1/2
Step-by-step explanation:
Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:
A(n) = 5 + (n-1) (1/6)
First term:
A(1) = 5 + (1-1) (1/6)
A(1) = 5 + (0) (1/6)
A(1) = 5
Fourth term:
A(4) = 5 + (4-1) (1/6)
A(4) = 5 + (3) (1/6)
A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 (simplifying)
Tenth term
A(10) = 5 + (10-1) (1/6)
A(10) = 5 + (9) (1/6)
A (10) = 5 + 9/6 = 6 3/6 = 6 1/2 (simplifying)
A square orange rug has a yellow square in the center. The side length of the yellow square is x inches. The width of the orange band that surrounds the yellow square is 11 in. What is the area of the orange band?
To find the area of the orange band, subtract the area of the yellow square from the area of the larger square.
Explanation:To find the area of the orange band, we need to subtract the area of the yellow square from the area of the larger square. The side length of the larger square is 8 inches because it is twice the side length of the yellow square, which is x inches. So, the area of the larger square is 8 * 8 = 64 square inches. The area of the yellow square is x * x = x^2 square inches. Therefore, the area of the orange band is 64 - x^2 square inches.
Final answer:
To calculate the area of the orange band, find the area of the larger square using the side length of x + 22 inches and subtract the area of the smaller yellow square with side length x. The expression for the area of the orange band is [tex](x + 22)^2 - x^2[/tex], which simplifies to 44x + 484 square inches.
Explanation:
To calculate the area of the orange band, you need to determine the area of the outer (larger) square and subtract the area of the inner (smaller) yellow square. First, find the side length of the larger square, which is the side length of the yellow square plus twice the width of the orange band, so it's x + 2(11) inches. Thus, the side length of the larger square is x + 22 inches.
Now, calculate the area of both squares. The area of the larger square is [tex](x + 22)^2[/tex] square inches, and the area of the yellow square is [tex]x^2[/tex] square inches. The area of the orange band is the difference between these two areas:
Area of the larger square:[tex](x + 22)^2[/tex]
Area of the yellow square: [tex]x^2[/tex]
Area of the orange band: [tex](x + 22)^2 - x^2[/tex]
To find the area of the orange band, you expand the expression [tex](x + 22)^2[/tex], which gives you [tex]x^2 + 44x + 484[/tex], then subtract the area of the yellow square [tex]x^2[/tex], resulting in 44x + 484 square inches, which is the area of the orange band.

It takes 2 1/5 kilometers of thread to make 2 5/6 boxes of shirts. How many kilometers of thread will it take to make 9 boxes of shirts.
It would take 6.99 kilometers of thread to make 9 boxes of shirts.
Step-by-step explanation:
Step 1; First we convert the mixed fractions into improper fractions. So
2[tex]\frac{1}{5}[/tex] becomes [tex]\frac{11}{5}[/tex] after multiplying 2 with 5 and adding 1 while 5 remains.
2[tex]\frac{5}{6}[/tex] becomes [tex]\frac{17}{6}[/tex] after multiplying the 2 with 6 and adding 5 while 6 remains.
Step 2; Next we equate the given data; [tex]\frac{11}{5}[/tex] kilometers of thread = [tex]\frac{17}{6}[/tex] boxes of thread. We must make the RHS equal to 1 to find out the kilometers of thread needed to make 1 box of shirts. So we multiply [tex]\frac{6}{17}[/tex] on both sides to make the RHS equal to 1.
[tex]\frac{11}{5}[/tex] × [tex]\frac{6}{17}[/tex] = [tex]\frac{17}{6}[/tex]× [tex]\frac{6}{17}[/tex]= 1, So [tex]\frac{11}{5}[/tex] × [tex]\frac{6}{17}[/tex] = [tex]\frac{66}{85}[/tex] km of thread. So [tex]\frac{66}{85}[/tex] kilometers of the thread is required to make 1 box of shirts so we multiply this with 9 to see thread required to make 9 boxes of shirts.
Thread required for 9 boxes of shirts = [tex]\frac{66}{85}[/tex] × 9= [tex]\frac{594}{85}[/tex] = 6.9882 kilometers of thread. This is rounded off to 6.99 kilometers of thread.

3a + 3b is equivalent to 3(a + 2b).
A true
B false
Answer:
B-false
Step-by-step explanation:
It is false because where the 2 is, has to be 3, other wise it won't make sense. Because it will not equal the same thing.
Final answer:
The expression 3a + 3b is not equivalent to 3(a + 2b). The first results in 3a + 3b, while applying the distributive property to the second expression gives 3a + 6b, clearly showing the expressions are different.
Explanation:
The statement 3a + 3b is equivalent to 3(a + 2b) is false. To show this, we can apply the distributive property of multiplication over addition, which states that for any real numbers a, b, and c, a · (b + c) = a·b + a·c. Using this property, we can expand 3(a + 2b) to get 3·a + 3·2b, which simplifies to 3a + 6b. This is not the same as 3a + 3b since 3b is not equal to 6b. Therefore, the expressions are not equivalent.

brainliest plz
Final answer:
Mikey the monkey ate more bananas than Mick, consuming 5 compared to Mick's 4 bananas.
Explanation:
Let's calculate how many bananas each monkey ate. We'll start with Mick the monkey, who had 10 bananas and ate two fifths of them.
Calculate two fifths of 10 bananas: (2/5) × 10 = 4 bananas.
Mick therefore ate 4 bananas.
Now, let's calculate for Mikey the monkey, who also had 10 bananas and ate half of them.
Calculate half of 10 bananas: (1/2) × 10 = 5 bananas.
Mikey ate 5 bananas.
Mikey the monkey ate more bananas than Mick because 5 is greater than 4.
Write two equations that would have the solution of (3,6)
Answer:
Step-by-step explanation:
3x1=3
2x3=6
2+1=3
3+3=6
Two equations that have the solution (3,6) include y = 2x and x + y = 9, satisfying the point when their values are substituted.
To write two equations that would have the solution of (3,6), we need to construct linear equations where the point (3,6) satisfies both equations. Here are two examples that fit the criteria:
The first equation could be y = 2x, because when x=3, then y=2(3)=6.
The second equation could be x + y = 9, because when x=3 and y=6, then 3 + 6 = 9.
These two examples clearly have the solution (3,6) when the respective values for x and y are substituted.
