7 over 2
Answers
The ratio of the number of days that do not begin with the letter T should be Based on the probability of the week = 5:7.
The following information should be used to solve this problem :
We know that there are 7 days a week.
Monday, Tuesday, Wednesday, Thursday, Friday Saturday, Sunday
There are two days on which the beginning letter is started by T i.e. Thursday and Tuesday.
And, there are 5 days that are started with different letters.
Monday, Wednesday, Friday Saturday, Sunday
Probability :
The probability of an event can be calculated by the probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.
P(A) = n(A)/n(S)
Where,
P(A) is the probability of an event “A”
n(A) is the number of favorable outcomes
n(S) is the total number of events in the sample space
P(A) = the number of favorable outcomes/ the total number of events in the sample space
= 5/7
Based on the above information, the ratio should be 5:7
Therefore
we can conclude that the ratio of the number of days that do not begin with the letter T should be 5:7.

Is the sum of two binominals is always a binomial? Why or why not?
Answers
Answer:
No
Step-by-step explanation:
Algebraic Terms:
1. Monomial - an algebraic term
2. Binomial - the sum of 2 algebraic terms
3. Trinomial - an algebraic sum in 3 terms
4. Polynomial - a function in more than 1 algebraic term
The sum of 2 binomials is not always a binomial because each of the two binomials might have different algebraic terms.
If the first binomial has 2 algebraic terms and the second binomial has 2 other algebraic terms and no single term crosses out its coefficients, the sum of both binomials will not be a binomial.

3) Sarah wants to buy a snowboard that has a total cost of $580, including tax. She has already
saved $135 for it. At the end of each week, she is paid $96 for babysitting and is going to save
three-quarters of that for the snowboard.
a) Write an inequality that can be used to determine the minimum number of weeks Sarah
needs to babysit to have enough money to purchase the snowboard.
b) Determine and state the minimum number of full weeks Sarah needs to babysit to have
enough money to purchase the snowboard.
Answers
Step-by-step explanation:
A) Let X= the number of weeks 46 times 3/4 = 72. And 135+72 x >_ 580
B) 135+72 x >_ 580. 580-135. 72/72 >_ 445/72
x >_ 6.2
She must work a minimun of 7 weeks to get $580.
The minimum number of weeks Sarah
needs to babysit to have enough money to purchase the snowboard is 135 + 72w ≥ 580
Given:
Total cost of snowboard = $580
Amount saved already = $135
Amount paid for baby sitting = $96
Amount saved from babysitting = 3/4 × 96
= 0.75 × 96
= $72
let
number of weeks = w
The inequality:
135 + (72 × w) ≥ 580
135 + 72w ≥ 580
Solve for w
135 + 72w ≥ 580
72w ≥ 580 - 135
72w ≥ 445
w = 445 / 72
w = 6.1805555555555
Approximately, 6 weeks
Therefore, the minimum number of full weeks Sarah needs to babysit to have
enough money to purchase the snowboard is 6 weeks

HelloI need help with a problemSimplify the expressionv^3+125/v^2-25
Answers
We are given the following expression:
\(\frac{v^3+125}{v^2-25}\)To simplify the expression we will factor the numerator and denominator. To factor the numerator we will use the following:
\((a^3+b^3)=(a+b)(a^2-ab+b^2)\)Applying the formula we get:
\(\frac{v^{3}+125}{v^{2}-25}=\frac{(v+5)(v^2-5v+25)}{v^2-25}\)Now, we will factor the denominator using the following:
\((a^2-b^2)=(a+b)(a-b)\)Applying the rule we get:
\(\frac{(v+5)(v^2-5v+25)}{v^2-25}=\frac{(v+5)(v^2-5v+25)}{(v+5)(v-5)}\)Now, we can cancel out the "v + 5", and we get:
\(\frac{(v+5)(v^2-5v+25)}{(v+5)(v-5)}=\frac{v^2-5v+25}{v-5}\)and thus we get the simplified form of the expression.

Angle A = tan^-1(11/5)
Angle C = 90 - tan^-1(11/5)
AC = sqrt(146)
Step-by-step explanation:
As this is a right triangle, we can apply the Pythagorean theorem a^2 + b^2 = c^2, where c is the hypotenuse while a and b are the legs, to solve for AC.
11^2 + 5^2 = AC^2
121 + 25 = AC^2
146 = AC^2
sqrt(146) = AC^2
Next, to find angle A, we can use one of the trigonometric functions. Let’s use tangent for simplicity. Tangent of an angle is “opposite divided by adjacent”. If we set the angle to A, opposite is side BC and the adjacent is side AB. Thus, tan(A) = 11/5 and tan^-1(11/5) = A.
Since the sum of angles in a triangle is 180, we can find angle C by setting up this equation: C = 180 - 90 - tan^-1(11/5), which is 90 - tan^-1(11/5)

Find two positive numbers whose difference is 14 and whose product is 1976

The positive numbers that the difference is 14 and the product is 1976 are 38 and 52.
How to find the positive numbers?The difference of the positive numbers is 14 and the products of the positive numbers is 1976.
The positive numbers are the numbers that are greater than zero.
Positive numbers includes fractions, In general, positive numbers are natural counting numbers.
Therefore,
let the numbers be x and y
Hence, the difference of the positive numbers is 14.
x - y = 14
The product of the positive numbers is 1976. Therefore,
xy = 1976
Make x the subject of the formula in equation(ii)
x = 1976 / y
Substitute the value of x in equation(i)
1976 / y - y = 14
14y = 1976 - y²
solve the quadratic equation formed.
y² + 14y - 1976 = 0
Hence,
y² - 38y + 52y - 1976
y(y - 38) + 52(y - 38)
(y - 38)(y + 52)
Therefore,
y = 38 and y = -52
The number is positive .
Therefore, we can only use 38.
y = 38
Substitute the value of y in equation(i)
x - 38 = 14
x = 14 + 38
x = 52
Therefore, the positive numbers are 38 and 52.

Use an equation to find the length of the scarf before it's unraveled.
Answers
Length of scarf before unraveling = 4.75 + 0.75 = 5.5.
Equation: Length before unraveling = 4.75 + 0.75
Sadie is knitting a striped scarf for her grandfather for his birthday, but discovers a mistake and has to unravel 0.75 of the scarf. After unraveling, the remaining part of the scarf is 4.75 long. To calculate the length of the scarf before it was unraveled, we can use an equation. The equation we will use is Length before unraveling = 4.75 + 0.75. We can interpret this equation as the length before unraveling being equal to the length after unraveling plus the amount unraveled. Therefore, the length of the scarf before unraveling is 4.75 + 0.75, which is equal to 5.5. This equation is useful for finding the original length of the scarf, as it takes into account the amount that was unraveled. Therefore, the original length of the scarf is 5.5.

center (-4, -7), tangent to x = 2
Answers
Answer:
(x + 4)^2 + (y + 7)^2 = 36
Step-by-step explanation:
The given information describes a circle with its center at (-4, -7) and tangent to the vertical line x = 2. To determine the radius of the circle, we need to find the distance between the center and the tangent line.
The distance between a point (x1, y1) and a line Ax + By + C = 0 is given by:
d = |Ax1 + By1 + C| / sqrt(A^2 + B^2)
In this case, the equation of the line is x = 2, which can be written as 1x + 0y - 2 = 0. Therefore, A = 1, B = 0, and C = -2. The center of the circle is (-4, -7), so x1 = -4 and y1 = -7. Substituting these values into the formula, we get:
d = |1*(-4) + 0*(-7) - 2| / sqrt(1^2 + 0^2)
d = |-6| / sqrt(1)
d = 6
Therefore, the radius of the circle is 6 units. The equation of a circle with center (h,k) and radius r is given by:
(x - h)^2 + (y - k)^2 = r^2
Substituting the values we have found, we get:
(x + 4)^2 + (y + 7)^2 = 36
This is the equation of the circle that satisfies the given conditions.

Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the sequence
11, 13, 15, 17, 19, ...
Determining the Recursive formula:
We know that a recursive formula is termed as a formula that specifies each term of the given sequence using the preceding terms.
From the given sequence it is clear that every term can be obtained by adding two to the previous term.
i.e. 13 = 11+2, 15 = 13+2, 17 = 15+2, 19 = 17+2
so
aₙ₊₁ = aₙ+2, for n ≥1
Therefore, a recursive formula is:
aₙ₊₁ = aₙ+2, for n ≥1Determining the Explicit formula:
Given the sequence
11, 13, 15, 17, 19, ...
An arithmetic sequence has a constant difference 'd' and is defined by
\(a_n=a_1+\left(n-1\right)d\)
computing the differences of all the adjacent terms
\(3-11=2,\:\quad \:15-13=2,\:\quad \:17-15=2,\:\quad \:19-17=2\)
The difference between all the adjacent terms is the same and equal to
\(d=2\)
also
\(a_1=11\)
so substituting \(d=2\), \(a_1=11\) in the nth terms
\(a_n=a_1+\left(n-1\right)d\)
\(a_n=2\left(n-1\right)+11\)
\(a_n=2n+9\)
Therefore, the Explicit formula is:
\(a_n=2n+9\)

First, we want to find the probability of having a costumer who choose Turkey sandwich.
In order to find it, we calculate the ratio of turkey sandwiches over the total number of orders.
Turkey sandwiches: 180
Total number of orders: 160 + 100 + 180 + 60 = 500
Ratio = turkey / total
Ratio = 180 / 500 = 0.36
