The area of a rectangle is 2x^2-7x-15. Determine binomials that represent the length and the width if this triangle
Answer:
[tex](x-5),(2x+3)[/tex]
Step-by-step explanation:
Given: area of a rectangle is [tex]2x^2-7x-15[/tex]
To find: binomials that represent the length and the width of the rectangle
Solution:
A polynomial that consists of two terms is known as binomial.
[tex]2x^2-7x-15=2x^2-10x+3x-15\\=2x(x-5)+3(x-5)\\=(2x+3)(x-5)[/tex]
Also, area of rectangle is length × breadth
So, length × breadth = [tex](2x+3)(x-5)[/tex]
So, length = 2x+3, breadth = x-5 or length = x-5, breadth = 2x+3

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.

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.
Look at the attached picture

Fatima surveyed a random sample of 80 students in her school about their
favorite type of pet. Of the students surveyed, 20 chose cats as their favorite
type of pet. If there are 597 total students at the school, what would be a valid
estimate for the number of students whose favorite type of pet is a cat?
Answer: 149
Step-by-step explanation:
out of 80 students, 20 said that they prefers cats, then the relative frequency is:
p =20/80 = 0.25
then, out of the 597 students a estimate of:
N = 0.25*597 = 149.25 like cats
We should round it down so we have a whole number, then we have a estimate of 149 students.

Which characteristics will prove that DEF is a right, isosceles triangle?
Answer:
the slopes of DE and EF are opposite reciprocals make the triangle Δ DEF a right triangle.
Step-by-step explanation:
The characteristics will prove that Δ DEF is a right isosceles triangle is the lengths of DE and EF are congruent, and their slopes are opposite reciprocals.
Now, the equal sides of DE = EF make the triangle Δ DEF an isosceles triangle and the slopes of two perpendicular lines are always the opposite reciprocals.
So the correct answer would be: The lengths of DE and EF are congruent, and their slopes are opposite reciprocals.
A right-angle triangle with two equal sides forming that right angle must be a right isosceles triangle.
What is a right isosceles triangle?
A triangle that has a right-angle and two equal sides is called a right-isosceles triangle.
Characteristics will prove that ΔDEF is a right isosceles triangle are as follows:
1. A right isosceles triangle must have a right angle.
2. Two sides of it must be equal. Obviously, the hypotenuse is the biggest side of the triangle. Apart from the hypotenuse, other two sides must be same. It will make their slope with the hypotenuse equal. Hence, the triangle will be also be isosceles.

As you can see, the cube and the cylinder are the same height and width. But, if you use their 2d counterparts, a square and a circle, a circle always takes up 78.5% of the squares area. Knowing this, we can take this knowledge and see that the cube will have a greater volume.

Find the surface are of the fish tank if the base is a regular octagon with side length 0.9 units and the height of the prism is 2 units
Answer:
19.11 square units
Step-by-step explanation:
The fish tank is composed by eight rectangles with base = 0.9 units and height = 2 units; and by a regular octagon at the bottom, which sides are 0.9 units long.
Area of each rectangle = 0.9*2 = 1.9 square units
Area of the regular octagon = 2*(1 + √2)*0.9² = 3.91 square units
Therefore:
Surface area of the fish tank = 8*1.9 + 3.91 = 19.11 square units

Find the Area of the composite figure
Answer:
Your answer is B.), 26 in.²
Step-by-step explanation:
So, what you do is you have to split it into two different shapes, find the areas of those, and then "put them back together" (add them together).
So, what I did is I made the whole top part one shape and then the bottom part. Here are the dimensions:
Top Part: 2 in. × 9 in.
Bottom Part: 4 in. × 2 in.
Now, you multiply and add them.
Top Part:
[tex]2*9=18[/tex]
Bottom Part:
[tex]4*2=8[/tex]
Add:
[tex]18+8=26in.^{2}[/tex]
Since it's a 2-dimensional figure, do not forget that when you label, you have to put a "2," as in "squared," like it's an exponent, but know that it is not an exponent. It's just so that people know, when looking at it, that it's the area of a 2-dimensional figure.

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
