To make it easier to understand, consider the exponent of a number with no decimals, with 1 decimal and with 2 decimals:
No decimals - the exponent has no decimals1 decimal - put the number as (a*10⁻¹)ⁿ = aⁿ10⁻ⁿ, there will be n decimals2 decimals - similar to above- (a*10⁻²)ⁿ = aⁿ10⁻²ⁿ, there will be 2n decimalsSince our given number is (0.23)⁹, with 2 decimal places, its exponent will have 2*9 = 18 decimals.

A deli is offering two specials. The roast beef special gives a profit of $2.30 per sandwich, and the turkey special gives a profit of $3.10 per sandwich. The roast beef special uses two slices of bread and three slices of cheese. The turkey special uses two slices of bread and four slices of cheese. The deli has 120 slices of bread and 160 slices of cheese available for the specials. The deli wants to maximize its profit selling specials. Let x represent the number of roast beef specials and y represent the number of turkey specials. What are the constraints for the problem?
Answers
Answer:
The constraints are as follows;
1) 2·x + 2·y ≤ 120
2) 3·x + 4·y ≤ 160
3) x = 2.30
4) y = 3.10
5) P = 2.3·x + 3.10
Step-by-step explanation:
The question is a word problem, with the analysis as follows;
The profit from the roast beef special per sandwich = $2.30
The profit from the turkey special per sandwich = $3.10
The number of slices of bread in the roast beef special = Two slices
The number of slices of cheese in the roast beef special = Three slices
The number of slices of bread in the turkey special = Two slices
The number of slices of cheese in the turkey special = Four slices
The number of slices of bread the deli has = 120 slices
The number of slices of cheese the deli has = 160 slices
Let 'x' and represent the number of roast beef special and 'y' represent the number of turkey special the deli makes, then we have the constraints as follows;
For the number of slices of bread used;
2·x + 2·y ≤ 120...(1)
For the number of slices of cheese used;
3·x + 4·y ≤ 160...(2)
x = 2.30
y = 3.10
The profit 'P' is given by the following equation
P = 2.3·x + 3.10.

Kathi had a rope of 63.45 m. She cut the rope into two pieces. If the length of one piece was 23.59 m, what was the length of the other piece?
Answers
Answer:length of the other piece=39.86m
Step-by-step explanation:
Total length of rope =63.45 m
length of one piece = 23.59 m
Since the rope was cut into two pieces, we subtract the length of known first piece from the total length
length of the other piece = 63.45 m-23.59 m=39.86m

The x-coordinate of the vertex of the function y=-x²+bx+3 is 10. Determine the y-coordinate of the vertex.
Answers
Answer:
103Step-by-step explanation:
Given function:
y = -x² + bx + 3The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = -b/2aThe given function has:
x = 10, and a = -1Find the value of b:
10 = -b / -2b = 20The function is:
y = -x² + 20x + 3The y-coordinate of the vertex is:
y = -(10²) + 20*10 + 3 = -100 + 200 + 3 = 103Answer:
Solution given:
y = -x² + bx + 3
we have
The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = [tex] \frac{ - b}{2a} [/tex]
we have
x = 10, and a = -1
Substituting value of a in -b/2a
we get
b = 20
now
The y-coordinate of the vertex is:
y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.

You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %
Answers
Answer:
75%
Step-by-step explanation:
You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %
Given the following
Total cards = 4 (6,7,8,9)
If the card is not 9, the required card will be (6,7,8)
Number of cards that are not 9 is 3
Probability = expected/total
Pr(not 9) = 3/4
express as percent
Pr(not 9) = 3/4×100
Pr(not 9) = 75%
Answer:
50%
Step-by-step explanation:
There are 4 cards, numbered 6, 7, 8, and 9. The numbers greater than 7 are 8 and 9. There are 2 numbers greater than 7.
P(greater than 7) =

4
Write your answer as a decimal. Then convert your answer to a percentage.

88 is a solution to 1/8 R = 11 because
Answers
Answer:
In this equation R would equal 88 because it satisfies the equation.
Step-by-step explanation:
You must solve for R by isolating the variable(which is R). To move the 1/8, multiply both sides by 8. You would do this because 8 is the reciprocal of 1/8. With R on it's own, to keep both sides equal multiply 11*8. That equals 88, which satisfies the equation, which is why 88 is the solution.

In the interval 0° < x < 360°, find the values of x for which sin x = 0.6691 Give your answer tot he nearest degree
Answers
Answer:
x are 42 and 138degees
Step-by-step explanation:
Given the expression sin x = 0.6691
sin x = 0.6691
Take the sin inverse of both sides
sin⁻¹(sin x) = sin⁻¹(0.6691 )
x = sin⁻¹(0.6691 )
x = 41.99
x = 42 degrees (to the nearest degree)
Since sin theta is positive in the second quadrant;
x = 180 -theta
x = 180 - 42
x = 138degrees
Hence the value of x are 42 and 138degees
