Answer: Let's call the number of bananas your character slipped on as "x". Then, the total points from slipping on bananas would be -3x. And since the total points from slipping on bananas during one race were at most -27, we can write an inequality to represent this:
-3x ≤ -27
Now we'll solve for x:
Divide both sides by -3:
x ≥ 9
So, the least number of bananas your character slipped on is 9.
To find the least number of seconds of race time, we need to multiply the number of bananas by 2 seconds per banana:
9 bananas * 2 seconds/banana = 18 seconds
So, the least amount of race time your character took to slip on bananas is 18 seconds.

The money borrowed by Alonzo at a simple interest rate of 8% for a time period of 2 years is $7000.
What is simple interest?
In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed). It is not the same as a fee that the borrower might pay to the lender or another entity.
Borrowers must pay lenders simple interest as a fee in exchange for a loan. For simple interest calculation, compounding interest is excluded from the calculation and just the original principal is used. Simple interest applies to all loans, not just specific ones. Additionally, it refers to the kind of interest that banks give their customers on their savings accounts.
Given,
Time period = 2 years
Rate of interest = 8%
The simple interest paid at the end of 2 years = $ 1120
The money borrowed or the principal amount is
Simple interest = (Principal amount * rate * time)
1120 = P * 0.08 * 2
P = 1120/0.16 = $7000
Therefore the money borrowed by Alonzo at a simple interest rate of 8% for a time period of 2 years is $7000.

A linear function is demonstrated by the line a.
Line a has a slope of one.
Y = x + 2 is the equation for the line a.
How do you calculate a line's slope?
Following points on line a (x,y) = (0,2) and are available in the figure (2,4)
Calculating the slope (m) involves using:
m= y^2-y^1/x^2-x^1
This results
m= 4-2/2-0
Analyze m = 1
Consequently, the line's slope is 1.
The formula for line aThe formula for this is y = m(x - x1) + y1.
We thus have:
y = (x - 0) + 2
y = x + 2: Compare the difference and the result.

There are 30 bacterial cells on a petri dish. each hour the number of cells doubles. after 5 hours, how many cells are there
a) Identify if it is growth or decay.
b) Write an equation to model the situation
c) Answer the question.
a) This situation represents exponential growth, as the number of bacterial cells is doubling every hour.
b) Let N be the number of bacterial cells on the petri dish at time t in hours. The equation to model the situation is:
N = 30 x 2^t
This equation represents exponential growth, as the number of bacterial cells is doubling every hour. The initial number of bacterial cells is 30 (when t = 0), and the number of bacterial cells at any time t is given by multiplying the initial number by 2 raised to the power of t.
c) After 5 hours, the number of bacterial cells on the petri dish is:
N = 30 x 2⁵ = 30 x 32 = 960
So there are 960 bacterial cells on the petri dish after 5 hours.
The exponential growth and exponential decayThe math subject that is relevant to the case above is exponential growth and exponential decay. These are mathematical concepts that describe the behavior of quantities that increase or decrease at a constant percentage rate over time.
Exponential growth refers to a situation where a quantity grows at a constant percentage rate over time. In the case above, the number of bacterial cells doubles every hour, which is an example of exponential growth.
Exponential decay, on the other hand, refers to a situation where a quantity decreases at a constant percentage rate over time. An example of exponential decay could be the decay of a radioactive substance.

big augie's pizza now offers triangle shaped pizzas. how long must the sides fo the pizza be to the nearest inch equal the size of a round pizza with a 17 inch diameter?
Answer:
Step-by-step explanation:
The area of a round pizza with a 17 inch diameter is:
A = πr^2 = π(8.5)^2 ≈ 226.98 square inches
To find the length of the sides of a triangle with the same area, we can use the formula for the area of a triangle:
A = (1/2)bh
where b is the base of the triangle and h is the height.
Since the triangle is equilateral (i.e., all sides are equal), the base and height are the same. Let's call this length x. Then:
A = (1/2)bh = (1/2)x(x/2) = x^2/4
Setting this equal to the area of the round pizza, we get:
x^2/4 = 226.98
Multiplying both sides by 4, we get:
x^2 = 907.92
Taking the square root of both sides, we get:
x ≈ 30.13
So the sides of the equilateral triangle should be about 30.13 inches long to have the same area as a round pizza with a 17 inch diameter. Rounded to the nearest inch, the sides of the triangle should be 30 inches long.

Quadrilaterals called trapezoids have two parallel and two non-parallel sides. It also goes by the name Trapezium. A trapezoid is a closed, four-sided form or figure that has a perimeter and covers a specific area. It is a 2D figure rather than a 3D one. The bases of the trapezoid are the sides that are parallel to one another. Legs or lateral sides refer to the non-parallel sides. The height is the separation between the parallel sides.

which terms are used to describe events that have no outcomes in common?
The term used to describe events that have no outcomes in common is called "Mutually Exclusive."
Probability is a measure of how likely an event is to occur. The probability of an event ranges from 0 to 1, where 0 means that an event will not occur, and 1 means that an event will certainly occur.
In Mutually Exclusive events, the probability of both events happening at the same time is 0, which means that the outcome of one event completely eliminates the possibility of the outcome of the other event. The probability of getting heads and tails at the same time is 0, as it is impossible for the coin to show both heads and tails at the same time.
In mathematical terms, Mutually Exclusive events are represented by
=> P(A) + P(B) = P(A or B),
where P(A) represents the probability of event A, P(B) represents the probability of event B, and P(A or B) represents the probability of either event A or B occurring.
To summarize, Mutually Exclusive events are events that have no outcomes in common and have a probability of 0 of occurring simultaneously.

Which quadrilateral has diagonals that are alwaysperpendicular bisectors of each other?1) square 2) rectangle 3) trapezoid4) parallelogram
The quadrilateral with diagonals that are always perpendicular bisectors of each other is a square. Correct option is 1.
In a square, the diagonals bisect each other at right angles, which means they intersect at a 90-degree angle. Moreover, since a square has four congruent sides and four right angles, the diagonals are also congruent. Thus, each diagonal is a perpendicular bisector of the other diagonal, splitting it into two equal segments.
In contrast, a rectangle has diagonals that bisect each other, but they are not always perpendicular. A trapezoid has only one pair of opposite sides that are parallel, and its diagonals do not bisect each other.
