[tex]\triangle~\fbox{\bf{KEY:}}[/tex]
A term is a thing that's added or subtracted.So let's compute the number of terms in this expression.
The first term is [tex]\pmb{10y^2}[/tex].
Is anything added or subtracted from 10y²?
Sure! [tex]\pmb{-3y}[/tex] is subtracted from 10y².
Also, 8 is added to -3y.
Thus, this expression has 3 terms.

The Father of the Bride flips out when he realizes that the hot dogs and buns don't
match. There are 8 hot dogs in a package and 12 buns in a package. How many
packs of hot dogs and how many packs of buns do you need to purchase in order to
have the exact same number of each?
Using the least common multiple, it is found that you need to buy 3 packs of hot dogs and 2 packs of buns to have the exact same number of each.
How to find the number of packs needed?First, we need to find the total number of each element, finding the least common multiple of the sizes of each package, that is, 8 and 12.
The lcm is found factoring them by prime factors, hence:
8 - 12|2
4 - 6|2
2 - 3|2
1 - 3|3
1 - 1
Hence, lcm(8,12) = 2³ x 3 = 24.
Then:
24/8 = 3.24/12 = 2.Which means that you need to buy 3 packs of hot dogs and 2 packs of buns to have the exact same number of each.

Answer: x = 103
Step-by-step explanation:
this is a 90 degree angle indicated by the box in the corner of the angle.
90 degree angles total 90 degrees.
X - 15 + 2 = 90
move the numbers to the other side of the equal sign to isolate the X
by doing the opposite
x = 90 + 15 -2
x = 103
check your work, X - 15 + 2 = 90
103 - 15 + 2 = 90

The height of female students in Cromartie High is normally distributed. If 95% of females are
between 57.6 and 70.4 inches tall centered about the mean, find the average height and standard
deviation for female students at Cromartie High.
Using the Empirical Rule, it is found that the mean is of 64 inches and the standard deviation is of 3.2 inches.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.The normal distribution is symmetric, hence the mean is given by:
M = (57.6 + 70.4)/2 = 64.
57.6 is two standard deviations below the mean, hence the standard deviation is found as follows:
57.6 = 64 - 2s.
2s = 6.4
s = 3.2.

Divide every single term of the expression by the GCF (Greatest Common Factor).So let's divide.
But first. we should work out the GCF.
Both terms have 3x in common, so we divide both terms by 3x:
[tex]\mathrm{6x^3+3x}[/tex]

To ensure that we've factored correctly, we can always use the distributive property, distribute 3x and see whether or not we end up with [tex]\mathtt{6x^3+3x}[/tex].

Gabrielle needs to rent a car while on vacation. The rental company charges $19.95, plus 15 cents for each mile driven. If Gabrielle only has $40 to spend on the car rental, what is the maximum number of miles she can drive?
Round your answer down to the nearest mile.
Answer:
133 miles
Step-by-step explanation:
The limited budget gives rise to an inequality that can be solved for the maximum number of miles.
__
setupThe rental cost for m miles will be the sum of the fixed charges and the product of the mileage charge and the number of miles.
cost = 19.95 +0.15m
We want this to be no greater than 40, so we have the inequality ...
40 ≥ 19.95 +0.15m
solutionThis two-step inequality can be solved in the usual way:
20.05 ≥ 0.15m . . . . . step 1, subtract 19.95 from both sides
133.667 ≥ m . . . . . . . step 2, divide by the coefficient of the variable
The maximum whole number of miles Gabrielle can drive is 133.
Consider the graph of f(x) = (x + 5)2 – 3. Rewrite the equation by making one change in the equation of f(x) so that the graph has no x-intercepts.
Using the discriminant of a quadratic equation, if the graph is translated shifted up 4 units, the graph will have no x-intercepts.
What is the discriminant of a quadratic equation and how does it influence the solutions?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The discriminant is:
[tex]\Delta = b^2 - 4ac[/tex]
The solutions are as follows:
If [tex]\mathbf{\Delta > 0}[/tex], and it has 2 x-intercepts.If [tex]\mathbf{\Delta = 0}[/tex], it has 1 x-intercept.If [tex]\mathbf{\Delta < 0}[/tex], it has no x-intercepts.In this problem, the function is given by:
f(x) = (x + 5)² - 3.
In standard form:
f(x) = x² + 10x + 22.
We want to find coefficient k for which the function has [tex]\Delta < 0[/tex], then:
f(x) = x² + 10x + 22 + k.
The coefficients are a = 1, b = 10, c = 22 + k, hence:
[tex]\Delta < 0[/tex]
10² - 4(22 + k) < 0
100 - 88 - 4k < 0
4k > 12
k > 3.
Hence, with k = 4, the function is shifted up 4 units, and the graph will have no x-intercepts.

Arun took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4 plus $4.25 per mile. The total fare was $110.25, not including the tip. How many miles was the taxi ride?
Here we must write and solve a linear equation to find the number of miles that Arun traveled in the taxi. We will find that Eva traveled 11 miles.
So we know that the taxi charges a fee of $4.10 and then a plus of $0.50 per mile.
So if you travel for m miles, the cost equation is:
C(m) = $4.10 + $0.50*m
Now, we know that for Eva the total fare (total cost) was $9.60, then we need to solve:
$9.60 = C(m) = $4.10 + $0.50*m
$9.60 = $4.10 + $0.50*m
$9.60 - $4.10 = $0.50*m
$5.50 = $0.50*m
$5.50/$0.50 = m = 11
This means that Arun traveled 11 miles in the taxi.
The Eva traveled 25 miles in the taxi.
It is required to find how many miles was the taxi ride.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
The taxi company charged a pick-up fee of $4 plus $4.25 per mile.
The total fare was $110.25.
The cost equation is:
C(m) = $4 + $4.25*m
Now, we know that for Eva the total fare (total cost) was $110.25, then we need to solve:
$110.25 = C(m) = $4 + $4.25*m
$110.25-$4=$4.25*m
$106.25=$4.25*m
m =25
