what does x=?........................
Answer:
x = -25 / 3
Step-by-step explanation:
10 / 3 = x / (-5/2)
10 / 3 * (-5 / 2) = x
x = -50 / 6
x = -25 / 3
Answer:
[tex]x=\frac{-25}{3}[/tex]
Step-by-step explanation:
[tex]\frac{10}{3}=\frac{x}{\frac{-5}{2} } \\\\\frac{-5}{2}*\frac{10}{3}=\frac{x}{\frac{-5}{2} }*\frac{-5}{2} \\\\\frac{-25}{3} =x\\\\x=\frac{-25}{3}[/tex]

www.g Suppose that 59% of people own dogs. If you pick two people at random, what is the probability that they both own a dog
Answer:
The value is [tex]P(O) = 0.3481[/tex]
Step-by-step explanation:
From the question we are told that
The proportion of people that own a dog is [tex]p = 0.59[/tex]
The number of people selected is n = 2
Generally the probability that the people selected owns a dog is mathematically represented as
[tex]P(O) = p^n[/tex]
=> [tex]P(O) = 0.59^2[/tex]
=> [tex]P(O) = 0.3481[/tex]

Find all zeros of ƒ(x)=x4–22x3+121x2.Then determine the multiplicity at each zero. State whether the graph will touch or cross the x-axis at the zero.
Answer:
0, 11, both multiplicity 2touch, not cross, at each 0Step-by-step explanation:
The function factors as ...
f(x) = x^4 -22x^3 +121x^2
f(x) = x^2(x^2 -22x +121)
f(x) = x^2(x -11)^2
The zeros are x=0 and x=11, each of multiplicity 2.
Because the multiplicity is even, the graph will touch at each zero, not cross.

find pb, if pj=14 and jb= 28
Answer:
42
Step-by-step explanation:
Based on the information given, point j is the midpoint, as it is shared by both line segments. Set the equation:
pb = pj + jb
Note:
pj = 14
jb = 28
Plug in the corresponding numbers to the corresponding variables:
pb = pj + jb
pb = 14 + 28
pb = 42
pb = 42 is your answer.
~
pj=14
jb=28
p=14/j
b=28/j
pb=(14/j)×28/j
pb=392/j²
j²=9.333≅
pb=392/9.333
pb=42.0015≅42
in 2016 the average Raleigh driver spent 18 hours in traffic jams, which accounted for 6% of their total driving time. How many hours did the average Raleigh driver spend behind the wheel in 2016
Answer: 300 hrs
The time spent behind the wheel by the average Raleigh driver in 2016 is 300 hrs
Step-by-step explanation:
Given that;
Raleigh driver spent 18 hours in traffic jams
And it accounts for 6% of their total driving time
Now
let total driving time be = x hrs
so
6% of total driving time = 18 hrs
6/100 × x = 18hrs
6x = 1800 hrs
x = 1800/6
x = 300 hrs
∴ The time spent behind the wheel by the average Raleigh driver in 2016 is 300 hrs

Matt is tiling his house and he needs to find out what are the largest square tiles that he could use to
tile an area 105 cm by 280 cm?
Answer:
the largest square tile is 35cmx35 cm
Step-by-step explanation:
1. Factorize 105 = 5*7*3=35*3
Factorize 280=10*7*4=2*5*7*4=35*8
The common factor is 35.
So Matt can tile 3 tiles 35x35 along the side 105 and 8 tiles along the side 280.
Total 24 pieces 35x35 are necessary to tile the area 105x 280 cm
( However the question is only about the largest tile that Matt could use and not about the quantity of the tiles)
An executive invests 29,000, some at 8% and the rest at 7% annual interest. If he receives an annual return of $2,230, how much is invested at each rate?
Answer:
Amount invested in A (8%) = $20,000
Amount invested in B (7%) = $9,000
Step-by-step explanation:
Given:
Total amount invested = $29,000
Interest rate A = 8% = 0.08
Interest rate B = 7% = 0.07
Annual return = $2,230
Find:
Amount invested in each
Computation:
Assume;
Amount invested in A = x
Amount invested in B = 29,000 - x
So,
Interest receive from A = x × 0.08
Interest receive from A = 0.08 x
Interest receive from B = (29000 - x) × 0.07
Interest receive from B = 2,030 - 0.07 x
Annual return = Interest receive from A + Interest receive from B
2,230 = 0.08 x + 2,030 - 0.07 x
x = 20,000
Amount invested in A = $20,000
Amount invested in B = 29,000 - $20,000
Amount invested in B = $9,000

Find the distance between the two points in simplest radical form.
(3,7) and (9,9)
Answer:
The answer is
[tex]2 \sqrt{10} \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula

Composition of the functions is
____ commutative.
Answer:
Composition of functions is sometimes commutative.
Step-by-step explanation:
Composition of the functions is sometimes commutative.
Under certain circumstances, they can be commutative. However, this is not guaranteed.
Consider, for example, the functions:
[tex]\displaystyle f(x) = x^2 \text{ and } g(x) = x^3[/tex]
Composition of the two functions yields:
[tex]f(g(x))=(x^3)^2=x^6 \\ \\ \text{ and} \\ \\ g(f(x))=(x^2)^3=x^6[/tex]
In this case, the composition is commutative.
Composition of functions is sometimes commutative.
Commutativity refers to the ability to change the order of operations without affecting the result. In terms of functions, it means that the order in which you perform the composition matters.
For example, if we have two functions, f(x) and g(x), the composition of f(g(x)) is not necessarily equal to g(f(x)). In other words, the result of applying one function followed by another is generally different from the result of applying them in the opposite order.
This lack of commutativity is due to the fact that the output of one function becomes the input of the other.
Thus, Composition of functions is sometimes commutative.

On a number line suppose point E has a coordinate of 1, and EG=11 What are the possible coordinates of G?
Answer:
- 10 and 12
Step-by-step explanation:
On a typical number line, we have basically two directions that we can move on. Either to the left where the numbers are negative, of to the right where the numbers are positive.
Given that point E has a coordinate of 1 on a number line, and we are told that the distance between E and another point on the number line is 11 (EG), the possible coordinates of point G are two (either we are moving to the right or to the left). Therefore, possible coordinates of G are:
1 - 11 = -10 (to the left)
1 + 11 = 12 (to the right)

Given a standard day, at what altitude is the true airspeed of an aircraft approximately twice of what the airspeed indicator reads
Answer:
40000ftMSL
Step-by-step explanation:
We know that airspeed is measured using a pilot tube
And the air pressure is a function of density given as
Pressure= 1/2 xdensityx V²
So at 40,000ftMSL
Is this is replaced for V in the equation then the density of air will be 1/4 that of sea level
So since we are deriving velocity from pressure and pressure is 1/4 so the velocity Will be half of its pressure since velocity is squared from The equation above

Two partners are starting a wedding planning business. The total investment is $45,000. Their investments are in the ratio 4:5. How much does each
investor contribute?
$20,000 and $25.000
$5,000 and $40.000
$15,000 and $30.000
$10,000 and $35.000
Answer:
Hey there!
Think of 45000 being split to 9 pieces.
Each piece would be 5000 dollars.
Thus, the ratio would be 20000 to 25000
Hope this helps :)
One partner will bring $20,000 and the other will bring $25,000.
The total investment is $45,000 and they will contribute by the ratio, 4:5.
First add up the ratio as this will form the denominator:
= 4 + 5
= 9
The amount that the first partner will pay is:
= Proportion / 9 x Total investment
= 4 / 9 x 45,000
= $20,000
The other partner will bring:
= 5 / 9 x 45,000
= $25,000
The partners will therefore bring $20,000 and $45,000
