what is the measure of angle 3? Sorryyyy the question got cut off
Answer:
142
Step-by-step explanation:
angle <3 is supplementary to 5x + 3
5x + 3 + 21x - 5 = 180 (because two angles are supplementary as well)
26x - 2 = 180 add 2 to both sides
26x = 182 divide both sides by 26
x = 7
<3 + 5x + 3 = 180 replace x with 7 and rewrite equation
<3 + 38 = 180 subtract 38 from both sides
<3 = 142

Mike needs to replace the carpet in his living room. The carpet he likes costs $7.50 per square foot to purchase and install. His living room measures 263.5 square feet. How much will it cost to replace the carpet?
Answer:
$1,976.25
Step-by-step explanation:
Since one square foot cost $ 7.50 we simply multiply that by 263.5.
263.5 × 7.50= $1,976.25
The table below shows the typical hours worked by employees at a company. A salaried employee makes $67,000 per year. Hourly employees get paid $25 per hour, but get $37.50 per hour for each hour over 40 hours.

Last week the number of bacteria in a petri dish was 2.25×102. This week the number of bacteria in the petri dish is 2.75×105. How many times more bacteria are in the petri dish this week?
Round the decimal to the nearest tenth.
(2.75 x 10⁵ ) / (2.25 x 10² )
= (2.75 / 2.25) x 10⁵⁻²
= 1.2 x 10³ times .
(That's 1,200 times as many.)
I hope this helps!
Answer:
1221.2 times more
Step-by-step explanation:
number of bacteria last week = [tex]2.25*10^2[/tex]
= [tex]2.25*100[/tex]
= [tex]225[/tex]
number of bacteria this week = [tex]2.75*10^5[/tex]
= [tex]2.75*100000[/tex]
= [tex]275000[/tex]
[tex]275000 - 225 = 274775[/tex]
[tex]274775 / 225 = 1221.2[/tex]

The answer is number 2
Step-by-step explanation:
Since the price of a quarter is 25 cents we put the .25 it next to the Q and since dimes are worth 10 cents we put the .10 next to the D. D + Q should equal 30 since that is the total number of coins and the other should equal 4.80
Determine f’s end behavior
f(x)= -5x^6+8x^5-1/ x^2 -9
Answer:
f(x) → -∞ as x → -∞
f(x) → -∞ as x → +∞
Step-by-step explanation:
The given function is;
f(x) = -5x^(6) + 8x^(5) - 1/(x² - 9x)
Using long division to divide this as attached, we have;
f(x) = -5x⁴ - 37x³ - 333x² - 2997x - 26973 + (-242757x - 1)/(x² - 9x)
Thus, the leading coefficient here is -5 and the polynomial degree is 4.
Since the leading coefficient is negative and the degree of the polynomial is an even number, then we can say that the behavior of the polynomial is;
f(x) → -∞ as x → -∞
f(x) → -∞ as x → +∞

Answer:
66 ft
Step-by-step explanation:
model: real life
1 inch : 12 ft
We have 5.5 inches so we need to multiply each side by 5.5 inches
model: real life
1 *5.5 : 12 *5.5
5.5 in: 66 ft
Answer:
66 feet
Step-by-step explanation:
1 inch of a model represents 12 feet of a real shuttle
5.5 inches as height of a model will represent 12 × 5.5 feet as height of a shuttle
=66 feet

points. On her next turn she loses another 30
points. What is Joanne's score now?
Answer:
390 points
Step-by-step explanation:
Previous points = 420 pointsPoints she lost = 30 points⇒ New score = (420 - 30) points
⇒ New score = 390 points
Joanne's score is now 390 points.
In one city, 24% of adult smoke. In groups of size 130 of adults , what is the variance of the number that smoke ?
Answer:
[tex]X=24[/tex]
Step-by-step explanation:
From the question we are told that:
Probability of having a smoker [tex]P(s)=0.24[/tex]
Sample size [tex]n=130[/tex]
Generally the equation for Variance X is mathematically given by
[tex]X= np(1-p) =[/tex]
[tex]X= (130)(0.24)(1-0.24)[/tex]
[tex]X = 23.712[/tex]
[tex]X=24[/tex]
The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on the parabola. Which equation can be used to model the image of the lens?
y = (x – 2)(x + 3)
y = (x – 2)(x + 3)
y = (x + 2)(x – 3)
y = (x + 2)(x – 3)
Given:
The image of a lens crosses the x-axis at –2 and 3.
The point (–1, 2) is also on the parabola.
To find:
The equation that can be used to model the image of the lens.
Solution:
If the graph of polynomial intersect the x-axis at c, then (x-c) is a factor of the polynomial.
It is given that the image of a lens crosses the x-axis at –2 and 3. It means (x+2) and (x-3) are factors of the function.
So, the equation of the parabola is:
[tex]y=k(x+2)(x-3)[/tex] ...(i)
Where, k is a constant.
It is given that the point (–1, 2) is also on the parabola. It means the equation of the parabola must be satisfy by the point (-1,2).
Putting [tex]x=-1, y=2[/tex] in (i), we get
[tex]2=k(-1+2)(-1-3)[/tex]
[tex]2=k(1)(-4)[/tex]
[tex]2=-4k[/tex]
Divide both sides by -4.
[tex]\dfrac{2}{-4}=k[/tex]
[tex]-\dfrac{1}{2}=k[/tex]
Putting [tex]k=-\dfrac{1}{2}[/tex] in (i), we get
[tex]y=-\dfrac{1}{2}(x+2)(x-3)[/tex]
Therefore, the required equation of the parabola is [tex]y=-\dfrac{1}{2}(x+2)(x-3)[/tex].
Note: All options are incorrect.

THANK YOUU
y = -19
I started by adding 18 to both sides(inverse operation) then dividing by -2 to isolate the variable. What you do to one side must be done to the other
