5x^2- 20 ÷ y - (8 + 13)
X=4 Y=5
Answer:
14
Step-by-step explanation:
AABC is isosceles.
AB = 3x - 4 and BC = 5x - 10.
AB = [?]
If AB = BC then set up the equation 3x - 4 = 5x - 10
Subtract 3x.
-4 = 2x - 10
Add 10.
6 = 2x
Divide by 2.
3 = x
AB is 3x - 4 so
3(3) - 4
9 - 4
5.
AB = 5
If AB is not equal to BC then this is not solvable.
But if they are I am sure AB = 5.
Hope this helps

In a petri dish, a certain type of bacterium doubles in number every 20
minutes.
There were originally 8, or 23 bacteria in the dish. After 140 minutes, the
number of bacteria has doubled 7 times, multiplying by 27.
Now the population of bacteria is 23.27. Expressed as a power, how many
bacteria are in the petri dish after 140 minutes?

Bart earns $6.30 per h. If his regular pay last week was $236.25, how many hours did he work?
Answer:
Bart worked 37.5 hours last week (37 1/2).

Mr. Leto plans to save money to buy a carpet. If he saves $50 each week for 30 weeks, he will have saved the exact amount of money needed to buy the carpet. If Mr. Leto instead saves $75 each week, how many weeks will it take him to save the same amount of money?
Answer:
Number of new weeks = 20 week
Step-by-step explanation:
Total money saves = $50 x 30
Total money saves = $1,500
Find:
Number of new week
Computation:
Total money saves = Number of money save per week x Number of new weeks
1,500 = 75 x Number of new weeks
Number of new weeks = 20 week

Find the inverse of function f. f(x)=9x+7
A. F-1(x)= -9x-7
B.F-1(x)= 1/9x-7/9
C.F-1(x)= 7x+9
D.F-1(x)= 7/9x-1/9
Answer:
B
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 9x + 7 ( subtract 7 from both sides )
y - 7 = 9x ( divide all terms by 9 )
[tex]\frac{1}{9}[/tex] y - [tex]\frac{7}{9}[/tex] = x
Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus
[tex]f^{-1}[/tex] (x) = [tex]\frac{1}{9}[/tex] x - [tex]\frac{7}{9}[/tex] → B
which number has a 9 that is 1/10 the value of the 9 in 296?
4x - 3= 10
What number is x
4x -3 = 10
Add 3 to both sides:
4x = 13
Divide both sides by 4:
x = 13/4
Answer:
x=3.25
Step-by-step explanation:
4x-3=10
Add 3 to both sides.
4x=13
Divide each side by 4.
x= 3.25

Determine the measure of ∠Z. images attached
Answer:
The answer is option DStep-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Z
To find the value of ∠Z we use tan
We have
[tex] \tan(∠Z) = \frac{28}{25} \\ ∠Z = { \tan }^{ - 1} \frac{28}{25} \\ ∠Z = 48.239700...[/tex]

−1 as a standard form.
A negative exponent means to move the decimal point to the left the number of the exponent.
10^-1 you would move the decimal 1 place to the left.
5.401 x 10^-1 = 0.5401
[tex]\huge\boxed{0.5401}[/tex]
We have the equation...
[tex]\boxed{5401*10^-^1=(?)}[/tex]
Multiply 5401 by 10⁻¹.
[tex]\boxed{5401*10^-^1=0.5401}[/tex]
Therefore, your final answer is [tex]\boxed{0.5401}[/tex]

I NEED ANSWER AND NEED TO SHOW WORK HELP!!!!
Answer:
formula to solve
Step-by-step explanation:
Regular Weekly Pay = Hourly Wage x Hours Worked
Overtime Weekly Pay = Hourly Wage x 1.5 x Overtime Hours
Overtime Hours = The amount of hours worked above-and-beyond 40
hours. If you worked 55 hours in a week, your overtime hours would
be 15.
Total Weekly Pay = Regular Weekly Pay + Overtime Weekly Pay
Total Salary = Weekly Pay x Work Weeks per Year
Example: If you earn $8.35 per hour, work 50 weeks a year, and
average 50 hours/week:
Regular Weekly Pay = 8.35 x 40 = $334
Overtime Weekly Pay = 8.35 x 1.5 x 10 = $125.25
Total Weekly Pay = $334 + $125.25 = $459.25
Total Salary = $459.25 x 50 = $22,962.50
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.17x + $15.89
Complete question :
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.17x + $15.89. How much did Hans pay for his trip?
Answer:
$92.39
Step-by-step explanation:
Given that:
Total distance = 450 miles
Amount charged for fees and taxes = $15.89
Amount charged ti redeem each mile = $0.17
In the equation:
Y = $0.17x + $15.89
X = distance Hans is flying
Y = cost of trip
Y = $0.17(450) + $15.89
Y = $76.50 + $15.89
Y = $92.39
