Answer:
The value of given expression is 3.8.
Step-by-step explanation:
Given:
[tex]1.8+0.5(y+6)-2^3[/tex]
We need to find the simplified value of given expression using y =14
Solution:
Now we will substitute y =14 we get;
[tex]1.8+0.5(y+6)-2^3\\\\1.8+0.5(14+6)-2^3[/tex]
Now using PEDMAS we will first solve the parenthesis we get;
[tex]1.8+0.5\times20-2^3[/tex]
Now we will solve the exponent function we get;
we know that;
[tex]2^3=8[/tex]
So we can say that;
[tex]1.8+0.5\times20-8[/tex]
Now we will solve the multiplication operation.
[tex]1.8+10-8[/tex]
Now we will perform addition operation.
[tex]11.8-8[/tex]
And finally we will perform subtraction operation.
3.8
Hence The value of given expression is 3.8.
Andy cut a tuna and a chicken sandwich into a total of 18 pieces. He cut the tune into 12 more pieces than the chicken. Andy are 5 pieces of the tuna. What fraction of the tuna did he eat?
The fraction is 5/15, which simplifies to 1/3. So Andy ate one third of the tuna sandwich.
The student's question involves determining the fraction of the tuna sandwich that Andy ate. Andy cut a tuna sandwich into 12 more pieces than the chicken sandwich and the total number of pieces was 18. Since tuna has 12 more pieces, we let the number of chicken pieces be x. Hence, the tuna pieces would be x + 12. The equation then is x + (x + 12) = 18. Solving this, we get x = 3 (chicken pieces) and x + 12 = 15 (tuna pieces).
Andy ate 5 pieces of the tuna sandwich, so the fraction of the tuna he ate is 5 out of the total tuna pieces, which is 15. Therefore, the fraction is 5/15, which simplifies to 1/3. So Andy ate one third of the tuna sandwich.

The maximum value of y=√(x+2)-1 on the interval [-2 ,2]
Answer:
1
Step-by-step explanation:
The square root function is monotonically increasing, so will have a maximum at the right end of any interval. Here the maximum is at x=2. That value is ...
y = √(2+2) -1 = 2 -1 = 1
The maximum value on the interval is 1.
What is the inverse of the function g(x) = -3(x+6)?
Answer:
g-1(x) = -x/3 - 6.
Step-by-step explanation:
Let g(x) = y = -3(x + 6)
y = -3x - 18
3x = - y - 18
x = -y/3 - 6
Now replace x by the inverse g-1(x) and y by x, so
g-1(x) = -x/3 - 6.

What is the length of Box B?
A.2in
B.3in
C.4in
D.9in
Answer:
B
Step-by-step explanation:
Because they have same volume we have :
V(boxA)=2*3*6=36[tex]in^3[/tex]
V(boxB)=3*4*l=12l
V(boxA)=V(boxB)

The ratios for sin C, cos C, and tan C in a right triangle are y/h, x/h, and y/x respectively, where y is the opposite side, x is the adjacent side, and h is the hypotenuse.
Explanation:To write ratios for sin C, cos C, and tan C in a right triangle, you need to refer to the lengths of the sides of the triangle relative to angle C. If we denote the opposite side to angle C as y, the adjacent side as x, and the hypotenuse as h, the ratios are defined as follows:
sin C = opposite/hypotenuse = y/hcos C = adjacent/hypotenuse = x/htan C = opposite/adjacent = y/xIn a practical scenario, if you know the magnitude of one side and the direction angle, you can use these ratios to find the scalar components of a vector in a coordinate system, solve problems involving the Law of Sines and Law of Cosines, or analyze wave functions in physics. For example, the Law of Sines relates the lengths of the sides of a triangle to the sines of its angles as follows:
a/sin A = b/sin B = c/sin C
Where a, b, and c are the sides of the triangle opposite to angles A, B, and C, respectively.

What is the sum of 2x^2 and 2x^3
For this case we have the following expression:
[tex]2x ^ 2 + 2x ^ 3[/tex]
The terms are not similar, so they cannot be added.
Examples of similar terms:
[tex]x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4[/tex]
Then, the expression given can only be rewritten as:
[tex]2 (x ^ 2 + x ^ 3)[/tex]
This is taking common factor 2 to both terms.

3(x+2)=−5−2(x−3)
x = ___
(type your answer as a number, "no solution" or "infinite solutions")
Answer:
x = -1
Step-by-step explanation:
3(x+2)=−5−2(x−3) multiply 3 and -2 with inside the parenthesis
3x + 6 = -5 -2x + 6 now add the like terms
3x + 2x = 1 - 6
5x = -5 simplify both sides
x = -1
The store bought a pair of shoes for $50, and sold it for $80.What percentage was the mark up
The markup percentage on the shoes that were bought for $50 and sold for $80 is 60%.
To calculate the markup percentage, you subtract the original cost from the selling price and then divide that number by the original cost. Finally, you multiply the result by 100 to get the percentage.
The formula looks like this: ((Selling Price - Original Cost) / Original Cost)× 100. Let's apply this formula to your question.
The store bought the shoes for $50 and sold them for $80. So the markup in dollars is
$80 - $50 = $30
Now, let's convert this to a percentage:
Markup Percentage =
[tex]= \frac{80-50}{50} \times 100 \\\\= \frac{30}{50} \times100\\\\ = 60\%[/tex]
The markup percentage is 60%.

Which statement describes the behavior of the function f (x) = 3x/4-x
The graph approaches –3 as x approaches infinity.
The graph approaches 0 as x approaches infinity.
The graph approaches 3 as x approaches infinity.
The graph approaches 4 as x approaches infinity.
Answer:
A. The graph approaches –3 as x approaches infinity.
Step-by-step explanation:
when looking at the problem F (x) + 3x/x-4 the answer would lead up to..
Finding the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain:
( − ∞ , 4 ) ∪ ( 4 , ∞ ) , { x | x ≠ 4 }
Range: ( − ∞ , − 3 ) ∪ ( − 3 , ∞ ) , { y | y ≠ -3 }
are what it leads to and seeing the range -3 would have x as infinite/ -∞
so A is the correct option to me
The statement that describes the behavior of the function f(x) = 3x/4-x is The graph approaches 0 as x approaches infinity.
Option B is the correct option.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The statement "The graph approaches 0 as x approaches infinity" is the correct statement that describes the behavior of the function f(x) = 3x/(4-x).
We can use the limit definition of approaching infinity.
When x becomes very large (positive or negative), the term 4 - x in the denominator becomes very small, approaching zero.
As a result,
The fraction 3x/(4-x) approaches zero as x approaches infinity.
This can be confirmed using L'Hopital's rule, which gives the limit of the function as 0/1, or simply by observing the graph of the function.
Thus,
The graph approaches 0 as x approaches infinity.

Triangle F G H. Angle F is 43 degrees, angle G is x degrees, angle H is (x minus 1) degrees.
42 degrees
43 degrees
68 degrees
69 degrees
Answer: 68
Answer:
69°
Step-by-step explanation:
The three interior angles in a triangle will always add up to 180°, so we have:
43°+x+(x-1)=180°
43°+2x-1°=180°
2x=180°-43°+1°
2x=138°
x=69°
