Answer:
About $43.69.
Step-by-step explanation:
1.65+0.42t=20 you minus the 3 minutes from the 23 minutes because those are paid for by the 1.65. Then for every extra minute, you pay 42 cents.
1.65+0.42t=20
Subtract the 1.65
0.42t=18.35
t≈43.69
Can anyone help with number 9 please
Answer:
A) 55
Step-by-step explanation:
angle 3 is an exterior angle. to find the interior angle of the triangle, subtract angle 3 from 180
180 - 110 = 70
all the angles in a triangle add up to 180.
since angles 1 and 2 are the same, you can call them x.
70 + 2x = 180
70 - 70 + 2x = 180 - 70
2x = 180 - 70
2x = 110
2x/2 = 110/2
x = 110/2
x = 55
Answer:
A.55
Step-by-step explanation:
The angle that is not numbered =70 because it is the supplementary angles of angle 3. if that is 70 a triangle add to 180 then 180-70=110. and 1 and 2 and equal so 110/2 =55

Find the inequality represented by the graph - khan academy
PLEASE HELP
Answer:
y ≤ x - 1
Step-by-step explanation:
The slope is 1 (every unit for x, there is a unit for y, rise/run is 1/1). The y-intercept is -1, because the line crosses the y-axis at -1. The graph is shaded below the line, and the line is solid, meaning that y is less than or equal to x -1, or y ≤ x - 1.

Finbar bought his home for $150,000 in 2010. Property values have increased 10% every year since he has owned the home. Which of the following equations can be ined to represent the price of the home x years after 2010?
- y = 150,000 (1.5)^x
- y = 150,000(1.1)^x
- y = 150,000(0.9)^x
- y = 150,000(0.5)^x
Answer:
Y=150,000*(1.1)*
Step-by-step explanation
As Every year the rate of increase is 10% therefore the rate 1+10%=1.1, and X is number of years. So, (1.1)*, and after x years to get the correct value you can multiply, y=150,000*(1.1)*
Answer:
y = 150,000(1.1)^x is the answer

Molly has already taken 5 quizzes during past quarters, and she expects to have 4 quizzes during each week of this quarter. Write an equation that shows the relationship between the number of weeks x and the total number of quizzes y. Write your answer as an equation with y first, followed by an equals sign.
Answer:
y = 5 + 4(w)
Step-by-step explanation:
Given that:
Consider y to be the total number of quizzes and x to be the number of weeks;
The number of quizzes already taken during the past quarters = 5
The number of quizzes to be each week = 4
Therefore, the total number of quizzes is represented by quiz given during the past quarter and the quiz to be given in the future during every week of the quarter.
i.e
Total number of quiz y = quiz already taken during the past quarter + number of quiz each week(total number of weeks)
y = 5 + 4(w)
This is the required relationship between the number of weeks x and the total number of quizzes y.
James is earning money to buy a bicycle for $100. For each dollar James earns, his mother gives him $1. So far he has earned $14 mowing lawns and $7 wash cars. How much more must James earn in order to but the bike??
Answer:
James needs to earn 78 more dollars.
Step-by-step explanation:
If you add up all of the money James has earned, (1 + 7 + 14), it equals 22. If you subtract 22 from 100, it equals 78. Therefore James needs to earn 78 more dollars.
Answer:
$58
Step-by-step explanation:
$14*2=$28 as her mum gives another dollar for each dollar he earns
$7*2=$14 as her mum gives another dollar for each dollar he earns
then 28 + 14 = 42
100 - 42=$58
Review my example on how to find the rate of change for a given set of data. Let (x, y) = (11, 12) and (x', y') = (15, 16). The formula to find the rate of change for the two order pairs is: (y' - y) / (x' - x) = rate of change, so (16 - 12) / (15 - 11) = 4/4 = 1, therefore, the rate of change is 1 *
I would have labeled the points as
(x1,y1) = (11,12)
(x2,y2) = (15,16)
then used the formula
m = (y2-y1)/(x2-x1)
However, your idea works as well. I don't see any errors with your steps. Nice work.

Jericho wants to start saving to
purchase a house. His goal is to save $92,400. If he deposits $56,000 into an account that pays 2.92% interest compounded daily, approximately how long will it take for his money to grow to the desired amount? Round your answer to the nearest tenth of a year.
a) 19.3 years
b) 21.7 years
c) 15.4 years
d) 17.2 years
Answer:
its B
Step-by-step explanation:
If he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that,
Principal(P) = $56,000
Rate(R) = 2.92%
Time(T) = x years
Interest(I)=?
The amount to be collected to save the money is,
=$92,400 - $56,000
=$36,400
Interest = $36,400
The formula for the simple interest is,
I=(P×R×T)/100
Substitute the given value as
[tex]\rm 36400=\frac{\left(56000\times \:2.92T\right)}{100} \\\\ \frac{\left(56000\times \:2.92T\right)}{100}=36400 \\\\ \frac{100\times \:56000\times \:2.92T}{100}=36400\times \:100 \\\\ 163520T=3640000 \\\\ T=\frac{1625}{73} \\\\ T=21.7 \ years[/tex]
Thus, if he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.

Answer:
y=-6/5x - 1
Step-by-step explanation:
Slope intercept form is y=mx+b so first lets get it into correct order by subtracting the 6x to the other side.
6x-6x+5y=-5-6x
This gives you
5y=-6x-5
Now you need to isolate the y since the 5 is being multiplied by the variable "y" we need to divide to to separate. Divide all terms by 5.
5y/5=-6/5x+(-5)/5
This gives you your final answer:
y=-6/5x - 1
Answer:
y= -6/5x +1
Step-by-step explanation:
6x + 5y=5 move variable to right and change the sign
5y =-5 -6x divide both sides by 5...
5y/5 = -5-6x/5
y= -1 -6/5x reorder terms (when yo do you need to change the sign
so the -1 becomes a positive 1.....thats using the communitive
property to reorder terms
5= -6/5x+1
Which of the following is a fifth degree trinomial with a quadratic term and a negative leading
coefficient?
13. The area A of a square is the length of a side / squared.
1
Answer:
Area = a²
Step-by-step explanation:
For a square, all 4 sides are equal. If a be the side of a square and A be its area. Then, the area of a square is given by :
Area = side²
or
Area = a²
Hence, the area of a square is square of the length of its side.

Step-by-step explanation:
V = √ 20 L to estimate the speed of a car, v , in miles per hour, based on the length, L , in feet, of its skid marks when suddenly braking on a dry, asphalt road. At the scene of an accident, a police officer measures a car's skid marks to be 108 feet long. Approximately how fast was the car traveling? Round your answer to the nearest tenth (one decimal place) of a unit.
Answer:
46.5 miles per hour
Step-by-step explanation:
Given that :
Speed of A car v in miles per hour based on length L in feets ;
V = √(20L)
Skid mark (L) = 108 feets
V = √(20 * 108)
V = √2160
V = 46.475800 miles per hour
V = 46.5 mph

A rectangular picture measures 6 inches by 9 inches. If a copy machine makes each of the two dimensions 113 larger, by what is the percent of increase in the area of the picture
Answer:
27.7% larger
Step-by-step explanation:
6 x 113% = 6.78
9 x 113% = 10.17
Old Area = 9 x 6 = 54 sq in
New Area = 6.78 x 10.17 = 68.95
(New - Old) ÷ Old = .277 = 27.7%
