Answer:
$172.80
Step-by-step explanation:
The phone cost $800
Decreases by 2/5 every year. So the cost would be 3/5 (instead of doing 800 - 800 *2/5 its easier to just do 800*3/5)
Here is a equation for this question:
[tex]800* (\frac{3}{5})^{t}[/tex]
t = time in years
So we can plug in 3 for t
[tex]800* (\frac{3}{5})^{3}[/tex]
[tex]800* (\frac{27}{125})[/tex]
[tex]172.8[/tex]
So the phone is now worth $172.80

on a computer assembly line, the company's goal is to have no more than 2% errors there are 220 computers assembled each day. the inequality representing the relationship between the number of computers assembled and errors (e) is shown below
e220 <0.02
how many computers out of 220 can have errors and stay within the company's of no more than 2% errors
A. e<=2
B. e<=4
C. e<4
D. e<2
Hi maryanne!
Answer:
C. e<4
Step-by-step explanation:
Since [tex]\frac{e}{220} \leq 0.02[/tex]
e [tex]\leq[/tex] 0.02 x 220
e [tex]\leq[/tex] 4.4 (multiply 220 both sides)
e [tex]\leq[/tex] 4.4
Thefore it can be e [tex]\leq[/tex] 4

Which of the following is a Pythagorean triple?
Answer:
C: 8, 15, 17
Step-by-step explanation:
The easiest way to do this is simply to memorize the first few Pythagorean triples. It saves time. But it can also be hard to remember that. To see if something is a triple...
1. [tex]a^{2} + b^2=c^2[/tex]. This means square the first one, the second and add. Then square the last one. The sum of the first two with the last one should be the same.
2. For this to work, they have to be in order from least to greatest. All of these are.
3. Let's fill in the equation:
8^2= 64.
15^2= 225.
225+64= 289
17^2= 289.
It matches! It's a triple.

Tyler packed 8 shirts for a trip. Six of the shirts are short-sleeved. He randomly selects a shirt from his suitcase, replaces the shirt, and then selects another.
The two times Tyler selects a shirt from the suitcase are __________ events.
The probability that he selects a short-sleeved shirt both times is ________.
options for blank 1: independent, dependent
options for blank 2 :15/28, 9/16, 3/4, 9/14
Answer:
independent
9/16
Step-by-step explanation:
The events are independent events since he puts the first shirt back
P( short sleeve) = number of short sleeve)/ total
= 6/8 = 3/4
P ( short sleeve, short sleeve) = 3/4 * 3/4 = 9/16

[tex] \frac{ \cos(x) + \sin(x) }{ \cos(x ) - \sin(x) } = \tan(45 + x) [/tex]
Answer:
First, you want to divide the numerator and denominator by the cosine(x), and afterwards, it looks like this...[tex]\frac{tan~x+1}{tan~x-1}[/tex]
Include 45 as one of the parameters and correlate with tan.[tex]\frac{tan~x+tan~45}{tan~x-tan~45}[/tex]
Next, you want to multiply the numerator and denominator by the conjugate of the denominator, in this case, tan x + tan 45.Lastly, simplify, and you have the answer as tan(45 + x)The sphere of mass m and radius r is rigidly attached to a thin rod of radius r that passes through the sphere at distance 12r from the center. A string wrapped around the rod pulls with tension t.
The expression for the angular acceleration of the sphere will be 20Tr/13MR².
What is angular acceleration?It should be noted that angular acceleration simply means the time rate of change of the angular velocity.
From the information given, I = (2/5(MR² + M(R/2)² = MR²(2/5 + 1/4) = 13MR²/20
The torque (Q) will be Tr. Therefore, the expression for the angular acceleration of the sphere will be:
= Q/I
= Tr/13MR²/20
= 20Tr/13MR²

A function f(x) has x-intercepts of –3 and –5. what is the constant term in the function? f(x) = x2 8x
The constant term in the function f(x) = x² + 8x + 15 would be 15.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
A function f(x) has x-intercepts of –3 and –5 means
f(x) = (x+3)(x+5)
f(x) = a(x + 3)(x + 5), here a is a multiplier
let a = 1 then
f(x) = (x + 3)(x + 5) (expand factors)
f(x) = x² + 8x + 15
thus, 15 is the constant term

A figure is composed of two cubes. The side lengths of the larger cube are twice the side length of the smaller cube. If the total volume of the cubes is 1,944 m3, what are the side lengths of the two cubes? Enter the smaller dimension first
The side lengths of the two cubes are 6 meters and 12 meters respectively.
How to calculate the volume of a cube?Mathematically, the volume of a cube is calculated by using this following formula:
Volume = m³
Where:
m is the side lengths of a cube.
Translating the word problem into an algebraic expression, we have;
m³ + (2m)³ = 1944
m³ + 8m³ = 1944
9m³ = 1944
m³ = 1944/9
m = ∛216
m = 6 meters.
For the bigger cube:
2m = 2 × 6
2m = 12 meters.
