Piano lessons with Ms. Cohen cost $30 for 3/4 of an hour. What is Ms. Cohen's hourly rate?
Answer:
$40.
Step-by-step explanation:
To find the hourly rate, we can divide the price and the time.
We know that Ms.Cohen charges $30 for 3/4 of an hour. So, we will perform:
[tex]30\div\frac{3}{4}[/tex]
We dividing fractions, we keep, change, and flip. Hence:
[tex]=30\times\frac{4}{3}[/tex]
Multiply:
[tex]=\frac{120}{3}=\$40[/tex]
Therefore, the hourly rate is $40.
And this is the hourly rate because it is $40/1 hour. We can ignore the 1, so it’s just $40 per hour.
Answer:
$40
Step-by-step explanation:
If is $30 for 3/4 then you add 1 more to get 4/4 you get $10 added to $40
A survey was conducted in a class with 20 students about their favorite sport. Five students chose basketball, 8 students chose football, and 7 chose soccer. Based on this information, predict how many would NOT choose soccer if there were 460 students in the survey. 150 30b 230 • 160
Answer: 299
Step-by-step explanation:
Out of 20 students, 5 students chose basketball, 8 students chose football, and 7 chose soccer.
Students chose basketball and football=5+8=13
Fraction of students not chose soccer = [tex]\dfrac{13}{20}[/tex]
Assume that the fraction remains the same.
If there were 460 students, then the number of students not chose soccer [tex]=460\times\dfrac{13}{20}\\\\=299[/tex]
Hence, the number of students not chose soccer =299
Each day a bobcat drinks about 3 times as much water as a Canada goose drinks. If the Canada goose drinks 0.24 liters of water each day, how much can a bobcat drink in one day? Convert the answer to mL.
Answer:
720 mlStep-by-step explanation:
Bobcat drinks 3 times as much as Canada goose drinks:
0.24 l * 3 = 0.72 l0.72 l = 0.72 * 1000 ml = 720 mlAnswer:
Bobcat can drink 720 mL of water in one day
Step-by-step explanation:
Amount of water a Canada goose drinks in a day = 0.24 L
According to the question each day a Bobcat drinks about 3 times as much water as a Canada goose drinks.
[tex] \therefore [/tex] Amount of water a Bobcat drinks in a day = 3 × 0.24 L
= 0.72 L
= 0.72 × 1000 mL
= 720 mL

76 – 2m < 11 + 3m
13
11
O
8
5
Answer:
13
Step-by-step explanation:
We subtract 76 from both sides
76 - 2m - 76 < 11 + 3m - 76
-2m < 3m - 65
Subtract 3m from both sides
-2m - 2m < 3m - 65 - 3m
-5m < -65
Multiply both sides by -1 and flip the signs
(-5m)(-1) > (-65)(-1)
We get
5m > 65
Divide both sides by 5 and we get
m > 13

How do you do this question?
Step-by-step explanation:
f(x) = ln(1+2x), a = 5, n = 3
Find the derivatives.
f⁽⁰⁾(5) = ln(1+2(5)) = ln(11)
f⁽¹⁾(5) = 2 / (1+2(5)) = 2/11
f⁽²⁾(5) = -4 / (1 + 2(5))² = -4/121
f⁽³⁾(5) = 16 / (1 + 2(5))³ = 16/1331
T₃(x) = ln(11) (x − 5)⁰ / 0! + 2/11 (x − 5)¹ / 1! − 4/121 (x − 5)² / 2! + 16/1331 (x − 5)³ / 3!
T₃(x) = ln(11) + 2/11 (x − 5) − 2/121 (x − 5)² − 8/3993 (x − 5)³
Find the fourth derivative.
f⁽⁴⁾(x) = -96 / (1 + 2x)⁴
So the next term of the series would be:
(-96 / (1 + 2x)⁴) (x − 5)⁴ / 4!
For 4.6 ≤ x ≤ 5.4,│f⁽⁴⁾(x)│is a maximum at x = 4.6. Therefore:
│R₃(x)│≤ │(-96 / (1 + 2(4.6))⁴) (4.6 − 5)⁴ / 4!│
│R₃(x)│≤ 0.000009
│R₃(x)│is always positive, so we can ignore the right two graphs. Only the top left graph is less than 9×10⁻⁶ on the interval.

Answer: $225 = $15 a + $ 10 c
Step-by-step explanation:
price = $225
concert ticket for adults= $15
concert ticket for children = $10
System of equation to represent scenario
a is variable for adult
c is variable for children
Total price = $15 a + $ 10 c
$225 = $15 a + $ 10 c

Peter hired a cleaning company to clean his house. The cleaning company charges a fixed fee of $15
plus $17 per hour to clean a house.
a. Write an equation that can be used to determine, c, the total amount in dollars that the cleaning
company charges to clean a house in h hours.
17t + 15 is the charge for "t" hrs of work.
b. The cleaning company charged a total of $83 to clean Peter's house. How many hours did it take to
clean Peter's house?
Answer:
y= total charge for cleaning
x= number of hours of cleaning
Equation y=15+17x
For example, if the company cleaned for 2 hours it would be y=17+15(2)
y=17+30
y= 30 dollars

For the past 25 days, jonathon has read for n minutes each day. His total number of minutes read is 875. Write an equation to express the number of minutes jonathon read.
Answer:
Required equation is: 25n = 875
Step-by-step explanation:
Let n be the number of minutes Jonathon read per day
Now
He read for 25 days and total 875 minutes
The equation will be:
[tex]25n = 875[/tex]
We can solve this equation to find the number of minutes each day
Using Division property of Equality
[tex]\frac{25n}{25} = \frac{875}{25}\\n = 35[/tex]
Hence,
Required equation is: 25n = 875
The regression analysis gives the equation

Question 16 not 15.
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
[tex]11x + 16 = (9x + 2) + 32[/tex]
[tex]11x + 16 = 9x + 34[/tex]
Subtract sides 16
[tex]11x + 16 - 16 = 9x + 34- 16[/tex]
Simplification
[tex]11x = 9x + 18[/tex]
Subtract sides 9x
[tex] - 9x + 11x = - 9x + 9x + 18[/tex]
Simplification
[tex]2x = 18[/tex]
Divide sides by 2
[tex] \frac{2x}{2} = \frac{18}{2} \\ [/tex]
[tex]x = 9[/tex]
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Answer:
x=9
Step-by-step explanation:
angle 4 = angle 1 + angle 2
11x + 16 = 9x + 2 + 32
combine like terms
11x - 9x = 2 + 32 - 16
2x = 34 - 16
2x = 18
x = 18/2
x = 9
Americans earning between $114,500 and $ 163,000 fall into the 35% tax bracket. This means they pay $6,250 plus 35% of income over $114,500. If you earn $ 135,000 what are your taxes?
Answer:
Your taxes are $13,425
Step-by-step explanation:
Taxes paid by Americans depend on their income. If they earn between $114,500 and $163,000, they must pay a fixed amount of $6,250 plus 35% of the income over $114,500.
If you earn $135,000, you definitely all into the described bracket. We need to calculate the income above the minimum $114,500:
taxable income=$135,000-$114,500=$20,500
Thus, you must pay:
Tax = $6,250 + 35% of $20,500
Tax = $6,250 + 35/100 $20,500
Tax = $6,250 + $7,175 = $13,425
Your taxes are $13,425
