Caterer A charges $15 per person and $100 to set up tables. Caterer B charges $20 per person and $50 to set up tables.
For what number of guests will the cost of Caterer A be the same as the cost of Caterer B? number or guest
Answer:
Number of guests = 10
Step-by-step explanation:
Given that:
Caterer A charges $15 per person and $100 to set up tables. Caterer B charges $20 per person and $50 to set up tables.
Let,
x be the number of guests.
A(x) = 15x + 100
B(x) = 20x + 50
For the cost to be equal;
A(x) = B(x)
15x + 100 = 20x + 50
100 - 50 = 20x - 15x
50 = 5x
Dividing both sides by 5
[tex]\frac{5x}{5}=\frac{50}{5}\\x=10[/tex]
Hence,
Number of guests = 10

Answer:
Tn = 8n - 2
Step-by-step explanation:
Given the arithmetic sequence
6, 14, 22, 30, 38
The nth term is expressed as;
Tn = a +(n-1)d
a is the first term = 6
d is the common difference = 14 - 6 = 22 - 14 = 8
Substitute into the formula;
Tn = 6 + (n-1)(8)
Tn = 6 + 8n-8
Tn = 8n - 2
Hence the nth term of the sequence is 8n-2

A grocery store sells 6 bottles of water for $4 and 18 bottles for $10. Is the cost of the water proportional to the number sold?
Proportional
Nonproportional
Answer:
Non Proportional
Step-by-step explanation:
Make a proportion:
For example say you want to test out how many bottles of water you can buy for $10
Proportion:
4 - 6
10 - ?
Solve: 10×6÷4=15
So technically, you could only get 15 bottles for $10. Therefore, this is a non proportional problem.

Consider the 4th roots of 16[cos(π) + i sin(π)].
The roots are located on a circle with center at the origin and radius of ....
The arguments of two successive roots differ by.... π units along the circumference of a circle.
Answer:
2 1/2
Step-by-step explanation:
The roots are located on a circle with a center at the origin and a radius of 4. The arguments of two successive roots differ by (1/2)π units along the circumference of a circle.
What is the Circumference of a circle?The circumference of a circle is defined as the product of the diameter of the circle and pi.
The 4th roots of 16[cos(π) + i sin(π)] are the 4th roots of -16i. These roots are located on a circle with a center at the origin and a radius of 4 because the 4th roots of a complex number are equally spaced on a circle with a radius equal to the absolute value of the complex number.
The arguments of two successive roots differ by π/2 units along the circumference of a circle. This is because there are 4 roots and the circle has a circumference of 2π, so each root is spaced 2π/4 = π/2 units apart along the circumference of the circle.
For example, the first root is located at (4, 0) on the complex plane, which corresponds to an argument of 0.
The second root is located at (0, 4) on the complex plane, which corresponds to an argument of π/2.
The third root is located at (-4, 0) on the complex plane, which corresponds to an argument of π.
The fourth root is located at (0, -4) on the complex plane, which corresponds to an argument of 3π/2.
Thus, you can see that the arguments of the roots differ by π/2 units.

What is the slope of a line perpendicular to the line whose equation is 2x-10y=100
Answer:
-5
Step-by-step explanation:
To find the perpendicular line, first rearrange this into slope intercept form.
y= mx + b
2x - 10y = 100
-10y = -2x +100
y = 1/5x - 10
The slope of a perpendicular line has a slope that is the receipt I’ll of and opposite of this line. The slope here is 1/5 so flip it and you have 5/1. It will also be negative since that slope was positive.

I'm guessing it's 1x, but the first number is always the slope.

what is the measure of <A in the triangle below
Answer:
∠A = 62°
Step-by-step explanation:
∠ACB = 180 - 116 = 64°
∠A + ∠B + ∠C = 180°
(3x - 13) + (2x + 4) + 64 = 180°
3x + 2x - 13 + 4 + 64 = 180°
5x + 55 = 180°
5x = 180 - 55
5x = 125
x = 125/5
x = 25
∠A = 3x - 13
∠A = 3(25) - 13
∠A = 75 - 13
∠A = 62°
You have two identical boxes which an interior dimensions of 8.0x8.0x8.0. You completely fill one of the boxes with wooden spheres that are 1.6 in diameter. The other box gets filled with wooden cubes that are 1.6 cm on each edge. After putting the lid on the filled boxes, you then measure the density of each. Which one is more dense?
Answer: The one filled with wooden cubes.
Step-by-step explanation:
First, the box filled with spheres will have empty space, this is for how spheres are, so independent of the radius of the sphere, we will always have some empty space inside the box.
In the case of the cubes, this does not happen. Furthermore, the dimension of the box are 8cm by 8cm by 8cm, and the cubes have a sidelength of 1.6cm
We know that:
1.6cm*5 = 8cm
Then we can perfectly fill the box with the wooden cubes (such that there is no empty space like in the previous case).
Because this box has no empty space and is filled with the same material as the other box, we can conclude that this box will have a larger mass than the one filled with spheres.
And we know that:
density = mass/volume.
Both boxes have the same volume, but the box with cubes has a larger mass, then the box with cubes will have a larger density.

Given: in a right triangle, cot0 = 28/45
1. what is csc0
2. what is sec0
Answer:
i) [tex]cosec0 = \frac{hypotenuse}{opposite side} = \frac{53}{45}[/tex]
ii) [tex]sec0 = \frac{hypotenuse}{adjacent side} = \frac{53}{28}[/tex]
Step-by-step explanation:
Step(i):-
Given that
[tex]cot 0 = \frac{28}{45} = \frac{adjacentside}{opposite side}[/tex]
Hypotenuse AC² = AB²+BC²
⇒ AC² = 45²+28² = 2809
⇒ AC = √2809
⇒ AC = 53
Hypotenuse AC =53
Step(ii):-
i) [tex]cosec0 = \frac{hypotenuse}{opposite side} = \frac{53}{45}[/tex]
ii) [tex]sec0 = \frac{hypotenuse}{adjacent side} = \frac{53}{28}[/tex]

The average person in the United States drinks 767 cups of coffee annually. How many quarts of coffee is that? Show your work. ( do not comment if you do not know or I will report )
Answer: 191.75 quarts.
Step-by-step explanation:
We know that:
1 quart = 4 cups.
Then:
1 cup = 1/4 quarts.
this means that 1 cup, is equal to 1/4 quarts.
Then 767 cups is equal to 767 times 1/4 quarts.
The change of units is simply:
767 cups = 767*( 1/4 quarts) = 191.75 quarts.

y = 3x - 10
y = 2x - 5
Answer:
This is the subtraction method
Y -3X = -10
(-Y -2x = -5) -Y + 2X = 5
Y -3X = -10
-Y + 2X = 5
-X = -5
X = 5 Now fill in the 5 for X and Y = 5
Answer:
x = 5, y = 5
or
(5, 5)
Step-by-step explanation:
they both equal y so they also equal each other.
3x - 10 = 2x - 5
3x - 2x = -5 + 10
x = 5
substitute x for 5
y = 3x - 10
y = 15 - 10
y = 5
edit, whops forgot to check
just plug the variables in with their values and see if it makes sense:
y = 2x - 5
5 = 2*5 - 5
5 = 10 - 5
5 = 5
since 5 does equal 5, the solution is correct.
