Answer:
Fraction of drink that is water = = 0.875 = 87.5 %
Explanation:
400 ml of squash is made by mixing 50 ml of cordial with water.
Total volume of squash = 400 ml
Total volume of cordial = 50 ml
Total volume of water = 400 - 50 = 350 ml
Fraction of drink that is water = Volume of water/ Volume of squash
= 350/400
= 7/8
= 0.875 = 87.5 %

The manager of a take-out pizza store needs to hire pizza makers and cashiers for the evening shift. The total number of employees of both kinds can be at most 16 and the ratio of cashiers to pizza makers must be at least 3 to 5. Also, each pizza maker can answer 12 phone calls per hour and each cashier can answer 4 calls per hour while the pizza shop must be able to handle at least 72 calls during peak hours.
(a) Create and graph a system of linear inequalities to model this problem
(b) Identify the solution region
(c) If each pizza maker gets $10 per hour and each cashier gets $6 hour, how many
pizza makers and how many cashiers should the manager hire in order to minimize
her cost?
Answer:
a) x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) see picture attached
c) 5 pizza makers and 3 cashiers should be hired.
Step-by-step explanation:
a) Let's define:
x: amount of pizza maker
y: amount of cashier
From conditions in the question:
x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) In the picture attached, the feasible region (also called solution region) is shown.
c) We want to minimize:
10*x + 6*y
subject to the previous restrictions.
It is known that the optimum solution is on the vertex of the feasible region (it is a linear system). Evaluating cost function at each point, we get:
10*1 + 6*15 = 100
10*5 + 6*3 = 68
10*10 + 6*6 = 136
Then, 5 pizza makers and 3 cashiers should be hired.

The point (a, b) is the top of a rectangle. After a transformation, it maps to the point (-a, b+3), what type of transformations happened?
a.) reflection over the line y= -1 and translated 3 units left
b.) reflection over the y = 1 and translated 3 units right
c.) reflection over the x-axis and translated 3 units down
d.) reflection over the y-axis and translated 3 units up
Answer:
d) reflection over the y-axis and translated 3 units up
Step-by-step explanation:
The reflection of the point across the y-axis (x,y)→ (-x,y)
b changed to b+3 so 3 units up
The type of transformation that happened to the rectangle is a reflection over the y-axis and translated 3 units up. Thus, the correct option is D.
What is transformation?The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.
Given that point (a,b) is the top of a rectangle. And after the transformation, the point of the rectangle is (-a, b+3). Therefore,
(a,b) → Reflected over y-axis → (-a,b)(-a,b) → Translated 3 unit up → (-a, b+3)Hence, the type of transformation that happened to the rectangle is a reflection over the y-axis and translated 3 units up. Thus, the correct option is D.

Carly and Simon are renting formal clothes for a wedding.
They found a rental company that charges a fixed fee of $80 plus an additional fee of $60 per hour.
If this information was put into an equation, which amount would represent the y-intercept?
A.
$80
B.
$60
C.
$140
D.
$4,800
Answer:
I think its either B, or C
Step-by-step explanation:
because in a equation your looking for the y intercept and the y intercept is usually the number without x by it.
The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80 thus option (A) is correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
As per the given,
They found a rental company that charges a fixed fee of $80 plus an additional fee of $60 per hour.
Total cost = 80 × number of hours + fixed cost
y = 86x + 80
y-intercept , x = 0
y = 60(0) + 80
y = 80
Hence"The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80".

Answer:
25. x = 17°
26. x = 50°
Step-by-step explanation:
25. There is a straight line which means :
108 +4x = 180
solving the obtained equation
108+4x = 180
4x = 180 - 108
4x = 72
x = 72/4
x = 17°
26. Again we can see that the angles in which 101 and x + 29 exists is a straight line . which means :
101 + x + 29 = 180
101 + 29 + x = 180
130 + x = 180
x = 180 - 130
x = 50°
So the answer of question no. 25 is 18 degree.
The answer of question no 26 is 50 degree.

? ≈ 52.3°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin ? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{19}{24}[/tex] , thus
? = [tex]sin^{-1}[/tex] ([tex]\frac{19}{24}[/tex] ) ≈ 52.3° ( to the nearest tenth )
Answer:
≈ 52.3
Step-by-step explanation:
You are given the opposite and hypotenuse side, leading you to use sin. However, since you're trying to find the angle measurement, you use the inverse of sin: [tex]sin^-1[/tex]
Set it up like this:
[tex]sin^-1(\frac{19}{24}) = ?[/tex]
When you solve, you get:
52.34
Round to the nearest tenth:

8. A bag of Skittles candy contains 8 red, 12 blue, 4 green, and 6 orange. What is
the probability of randomly choosing a green candy, replacing that candy and
choosing another green candy? *
Answer:
it is a 26:4 probability if you simplify it it would be 6.5:1
Step-by-step explanation:
The probability of randomly choosing a green candy, replacing that candy and choosing another green candy is 1/75 and this can be determined by using the given data.
Given :
A bag of Skittles candy contains 8 red, 12 blue, 4 green, and 6 orange.
The following steps can be used in order to determine the probability of randomly choosing a green candy, replacing that candy and choosing another green candy:
Step 1 - First, determine the total number of candies in the bag.
[tex]\rm Total\; Candy = 8 + 12 + 4 +6[/tex]
[tex]\rm Total\; Candy = 30[/tex]
Step 2 - The total number of green candies in the bag is 4.
Step 3 - So, the probability of randomly choosing a green candy, replacing that candy and choosing another green candy is:
[tex]P = \dfrac{4}{30}\times \dfrac{3}{30}[/tex]
Step 4 - Simplify the above expression.
[tex]P = \dfrac{12}{900}[/tex]
[tex]p=\dfrac{1}{75}[/tex]
The probability of randomly choosing a green candy, replacing that candy and choosing another green candy is 1/75.

In how many ways can the first 4 guest arrive at a party if 15 guest have been invited
Answer:
The first 4 guests can arrive at party in 1365 ways if 15 guest have been invited
Step-by-step explanation:
Total number of guests invited = 15
We are supposed to find in how many ways can the first 4 guest arrive at a party if 15 guest have been invited
We will use combination
Formula :[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]
Substitute n = 15 and r = 4
So,Total no. of ways = [tex]\frac{15!}{4!(15-4)!}=1365[/tex]
Hence the first 4 guests can arrive at party in 1365 ways if 15 guest have been invited
Answer:
