Ryan used 50 apples to make several pies. He put the same number of apples in each pie. He had 1 apple left over. How many pies did he make ?
Answers
Answer:
7
Stepbystep explanation:
501 = 49
Since all pies must have the same amount of apples, we can do √49 and get 7, meaning there are 7 pies with 7 apples each.
Answer: 7
Stepbystep explanation: of he had 1 apple left, he used 49 Apples.
if he used sane number of apple in each pie, we can use square root of 49 which is 7

Answers
Pay means loss is done as money is given to someone Earn means profit as money is taken from someone
So
here
rate of pay=30$ per hour
If hours be x
Question asked to plot a equation to calculate profit so all the expenses or loss should be deducted,here the constant loss is of 150 so 150 should be subtracted
The equation in slope intercept form
y=mx+by=30x150
Answer:
d) y = 30x  150
Stepbystep explanation:
Let x = number of hours worked
Let y = profit earned
Profit is the amount left after expenses are deducted.
Given:
Terry earns $30 per hour walking dogs
⇒ y = 30x
Given:
Terry pays $150 each month to a grooming service
This is Terry's expenses, so we must deduct this amount from the amount he earns walking the dogs to calculate the final profit:
⇒ y = 30x  150

2. The population of a school is 800 students and is increasing at a rate of 2% per year. Write an
exponential growth function, then find the population of the school after 9 years.
Answers
Answer:
1.) y=800e^(0.02t)
2.) 957.76 (or 958 if rounding up is required)
Stepbystep explanation:
1.) Since the increase is in years and our time is in years, we can use the function y=Pe^(rt) where P is our beginning value, r is rate (as a decimal) and t is time. Substitute the values P=800, r=0.02 to get y=800e^(0.02)t.
2.) Solving the equation above, we substitute t for 9, we get:
Y=800e^(0.02*9)
Y=800e^(0.18)
Y=800*(1.1972)
Y=957.76
Since it asks for population, you may or may not need to round to 958.

Lamar is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant charges $35 for the meal, plus $4 per kilogram for the lobster he picks. At the second restaurant, Lamar would pay $3 per kilogram for the lobster, in addition to $44 for the meal. Lamar realizes that, in theory, dinner at both restaurants could cost the same amount if the lobster had a certain weight. How much would Lamar pay for his dinner? What is the weight?
Dinner would cost $__ at either restaurant if Lamar's lobster weighed __ kilograms.
Answers
Answer:
The weight : 9 pound
Lamar would pay for his dinner : $71
Stepbystep explanation:
Let x represent the weight of the lobster
the cost of the dinner at restaurant 1 is 4x + 35
the cost of the dinner at restaurant 2 is 3x + 44
Now ,we have to solve the equation :
4x + 35 = 3x + 44
3x  35 3x  35 > trying to get all x terms on one side. other just #
4x  3x = 44  35
⇔ 1x = 9
⇔ x = 9
In this case Lamar would pay the same amount for his dinner at any restaurant:
the price = 4×(9)+35 = 71
= 3×(9)+44 = 71.

Jace gathered the data in the table. he found the approximate line of best fit to be y = –0.7x 2.36. a 2column table with 5 rows. the first column is labeled x with entries 0, 1, 4, 5, 7. the second column is labeled y with entries 3, 1, 0, negative 2, negative 2. what is the residual value when x = 5? –3.14 –0.86 0.86 3.14
Answers
The residual value is the difference in the value of the y coordinate between the real value and the expected value. The residual value will be equal to 0.86.
What is residual value?
The residual value is the difference in the value of y coordinate between the real value and the expected value.
Residual Value = Real value of y  The predicted value of y
The value of y in the table is 2 when the value of x is 5. And as per the function, the value of y when the value of x is 5 can be written as,
[tex]y = 0.7x+2.36\\\\y = 0.7(5)+2.36\\\\y= 3.5+2.36\\\\y=1.14[/tex]
Now, the residual value can be written as,
[tex]\text{Residual Value} = \text{(Value of y in the table)}  \text{(Value of y as per the function)}\\\\\text{Residual value} = 2  (1.14)\\\\\text{Residual value} = 2+1.14\\\\\text{Residual value} = 0.86[/tex]
Hence, the residual value will be equal to 0.86.

The probability of picking a chocolatecovered cherry is 0.
The probability that an a fell on the floor is 0.08
The probability that an a or a o would be picked is 0.36
The probability a girl would be picked is 1.
What is the probability?
Probability is used to calculate the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of picking a chocolatecovered cherry is zero because there is no chocolatecovered cherry in the bag.
The probability that an a fell on the floor = number of a in the letter / total number of letters
= 1/13 = 0.08
The probability that an s or a o would be picked is = (number of s in the letter / total number of letters) + (number of 0 in the letter / total number of letters)
= 4/11 + 0 = 4/11 = 0.36
The probability a girl would be picked is one since its an allgirls school.

Answers
The equation of the line of best fit of Hannah's dataset represented by the graph is y = 1.25x  1
How to determine the equation of the line of best fit?
From the given figure, we have the following points on the line of best fit:
(x,y) = (2,1.5) and (4,4)
Start by calculating the slope (m) using:
[tex]m = \frac{y_2 y_1}{x_2 x_1}[/tex]
So, we have:
[tex]m = \frac{4 1.5}{4  2}[/tex]
Evaluate the differences
[tex]m = \frac{2.5}{2}[/tex]
Divide
m = 1.25
The equation is then calculated using:
y = m(x  x₁) + y₁
So, we have:
y = 1.25(x  2) + 1.5
Open the bracket
y = 1.25x  2.5 + 1.5
Evaluate
y = 1.25x  1
Hence, the equation of the line of best fit is y = 1.25x  1

Side lengths ON and OR are radii of the circle O.
So, we have:
OR = ON = 5 units
The chord RN has a length of 5 units.
So, the perimeter of the triangle is:

Answer:
sinA = 0.79 tanA = 1.3
Stepbystep explanation:
Step1:
Find the length of the line going through the middle from A to C by using pythagorean theorem.
a = 13
b = 12
c= ?
c = sqrt(a^2 + b^2)
c = sqrt(13^2 +12^2)
c = 17.69
Step 2:
Use pythagorean theorem again to find the length of the line going from A to D.
a = ?
b = 14
c = 17.69
c^2 = a^2 + b^2
Now solve for a.
a^2 = c^2  b^2
a = sqrt(c^2  b^2)
a = sqrt(17.69^2  14^2)
a = 10.81
Step 3:
Use trignometry to find the values of sinA and tanA
sinA = opposite/hypotenuse = 14/17.69 = 0.79
tanA = opposite/adjacent = 14/10.81 =1.3

For two subsets A and B of the universal set U, we have:
[tex]n(A \cup B) = n(A) + n(B)  n(A \cap B)[/tex]
Assume that:
A and B be the subsets of what happens on each day.
Then in the days of last several weeks , we take:
A = set of days which had rainB = set of days which had high winds,
then, as per the data given, we get:
n(A) = number of days seeing rain = 67n(B) = number of days seeing high winds = 23 n(A ∩B) = number of days seeing both rain and high winds = 13
Thus, we get:
[tex]n(A \cup B) = n(A) + n(B)  n(A \cap B)\\n(A \cup B) = 67 + 23  13 = 77[/tex]
Thus, n(A ∪B) = number of days seeing either rain or high winds = 77
Thus, the number of days that had either rain or high winds for the considered case is 77
