Answer:
Step-by-step explanation:
General equation of line
y = mx + c
m is slope
y = (1/9)x - 1
1/9 is slope
Since the other line that passes through the point is perpendicular, the product of both slopes is -1
1/9 * m = -1
m = -9
Using point-slope method
y-y1 = m(x-x1)
y-3 = -9(x-(-1))
y-3 = -9(x + 1)
y-3 = -9x -9
y = -9x-6
Makayla has 90 minutes to answer 36 questions on a school survey. How many minutes per
question does she have?
Answer:
Makayla has 2 and a half minutes to answer each question.
Step-by-step explanation:
To get two and half you will have to divide 90 from 36 then you get 2 and a half minutes. hope this helps =D
By using division as mathematical operation,
Makayla need 2 and half minutes to answer each question
What is division?"The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication. In simple words, division can be defined as the splitting of a large group into smaller groups such that every group will have an equal number of items. It is an operation used for equal grouping and equal sharing in mathematics."
We have
Number of minutes to answer 36 questions = 90
We have to divide 90 by 36
= [tex]\frac{90}{36}[/tex]
= 2.5 minutes
Hence, By using division as mathematical operation, Makayla need
2 and half minutes to answer each question.

Answer:
A=14
Use formula A^2+B^2=C^2
Answer:
∠ A ≈ 24°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{MR}{AR}[/tex] = [tex]\frac{6}{15}[/tex] , thus
A = [tex]sin^{-1}[/tex] ([tex]\frac{6}{15}[/tex] ) ≈ 24° ( to the nearest degree )

(4 + 2)
ANSWER: 100=5*6
100=30
HOPE IT HELPS!
Answer:
x = 3 1/3
Step-by-step explanation:
Let's go over the order of operations.
P: Parentheses
E: Exponents
M/D: Multiplication/division (in order of appearance)
A/S: Addition/Subtraction (in order of appearance)
100 = 5*(4 + 2)
Since there are values in parentheses, solve those first: 100 .= 5x(6).
Next, multiply 5x by 6. 100 = 30x.
Finally, divide each side by 30 to find the value of x. 3 1/3 = x
Therefore, the value of x is 3 1/3.
(Note: this is assuming the term "x" is a variable, and not the multiplication sign, *.)
Mr. Morris asked Rob to shovel the snow from his driveway every day that it snowed during the month of January. He agreed to pay Rob $0.01 for the first day, $0.02 for the second day, $0.04 for the third day, $0.08 for the fourth day, and so on. If it snowed for 13 days in January, how much would Mr. Morris pay Rob on the 13th day?
Do not answer if you do not know. Only good answers with explanations.
Answer:
Total amount to be paid on 13th day is $40.96.
Step-by-step explanation:
Mr. Morris pays Rob $0.01, $0.02, $0.04 ..... on 1st, 2nd , 3rd .... day respectively.
We can clearly see that the next number is becoming double of the previous value.
The above sequence of numbers are in a Geometric Progression with
First term, a = 0.01 and
Common ratio, r = 2
We have to find the total amount paid on 13th day.
We know that the [tex]n^{th}[/tex] term of a GP is given by:
[tex]a_{n} =ar^{n-1}[/tex]
Where, a is the first term of GP
r is the common ratio
We have to find the [tex]13^{th}[/tex] term of the GP as per question statement.
Putting the values in the formula above:
n = 13
a = 0.01 and
r = 2
[tex]a_{13} = 0.01 \times 2^{13-1}\\\Rightarrow 0.01 \times 2^{12} \\\Rightarrow 0.01 \times 4096\\\Rightarrow 40.96[/tex]
Total amount to be paid on 13th day is $40.96.

answer fast please!
Answer:
25.1
Step-by-step explanation:
1. Find the radius of the inner circle
(the formula for the circumference of a circle is [tex]C=2\pi r[/tex])
To find the radius of the inner circle, you would plug in the given information so that your equation looks like this:
[tex]22=2(\frac{22}{7} )r[/tex]
then solve for [tex]r[/tex]
[tex]r=3.5[/tex]
2. add [tex]4[/tex] to the radius of the inner circle
[tex]3.5+4=7.5[/tex]
3. find the circumference of the outer circle using [tex]7.5[/tex] as the radius
[tex]C=2(\frac{22}{7})7.5[/tex]
[tex]C=47.1[/tex]
4. Subtract the circumference of the inner circle from the circumference of the outer circle
[tex]47.1-22=25.1[/tex]

12+18 = 15
122+ 182 – 152
Answer:
12^2 + 15^2 = 18^2
Step-by-step explanation:
If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle
a^2 + b^2 = c^2
12^2 + 15^2 = 18^2
If this is true, then the triangle is a right triangle

Plz help ASAP!! A surgical technique is performed on eight patients. You are told that there is an 80% chance of success. Find the probability that the surgery is successful for fewer than two patients. Please show your work. Hint: the answer is 0.000084.
Answer:
This is a fairly simple binomial distribution. We know it's binomial, because we're looking for a "fixed" number of patients, not the "first" like a geometric.
You can use your calculator:
binomcdf(n,p,Kr)
n=population, p=probability, Kr=number you're looking for
binomcdf(8,.8,1)
We have to do 1, not 2, because it says fewer than 2, which means 1.

At the amusement park each students is given $16 dollars for food. This covers the cost of 2 meals plus $4 for snacks. how much money does the school expect each student to spend per meal. Which equation can be used to represent this situation? plz help now if u can
Answer:
16 = 2x + 4
Step-by-step explanation:
The total amount of money they are given is $16. That is split up into 2 equal groups with 4 left over. So you'd have to subtract 4 from both sides. Then divide both sides by 2. This will give you the answer to how much money they expect the students to spend on food.

If a wiggling string has a natural frequency of 34.5 Hz to produce 4 harmonics, what is the period of the string?
Answer:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s
Step-by-step explanation:
For this case we know the frequency associated to the 4 harmonic.
We know that by definition the frequency is the inverse of the period:
[tex] f= \frac{1}{T}[/tex]
If we solve for the period we got:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s
