a meteorologist predicted that there would be 1.0 inches of rainfall from a storm instead there was 2.2 inches of rainfall
Answers
The percentage change of the rainfall the meteorologist predict is 55%
How to determine the percentage change of the rainfall the meteorologist predict?From the question, we have the following parameters that can be used in our computation:
Predicted amount of rainfall = 1.0 inches
Actual amount of rainfall = 2.2 inches
The percentage change of the rainfall the meteorologist predict is calculated as
Percentage change = (Actual amount of rainfall - Predicted amount of rainfall)/Actual amount of rainfall * 100%
Substitute the known values in the above equation, so, we have the following representation
Percentage change = (2.2 - 1.0)/2.2 * 100%
Evaluate the difference in the above equation, so, we have the following representation
Percentage change = 1.2/2.2 * 100%
Evaluate
Percentage change = 0.55 * 100%
So, we have
Percentage change = 55%
Hence, the percentage change is 55%

Find the zeros: 3r^2 − 16r − 12 = 0
Answers
Answer:
r = 6, r = - ⅔
Step-by-step explanation:
Given the quadratic equation, 3r² - 16r - 12 = 0:
where a = 3, b = -16, and c = -12.
Use the quadratic formula to find the x-intercepts:
\(r = \frac{-b +/- \sqrt{b^{2}-4ac } }{2a}\)
\(r = \frac{16 +/- \sqrt{(-16)^{2}-4(3)(-12) } }{2(3)}\)
\(r = \frac{16 +/- \sqrt{256 - 144 } }{6}\)
\(r = \frac{16 +/- \sqrt{400} }{6}\)
\(r = \frac{16 + 20}{6} = \frac{36}{6} = 6\) , \(r = \frac{16 - 20}{6} = - \frac{4}{6} = -\frac{2}{3}\)
Therefore, the roots (zeroes) of the given quadratic equation are:
r = 6, r = - ⅔

What kind of multi step do I have to do to prove a is parallel to b and m parallel to n.

The proof that line n is perpendicular to both a and b is proved below using definition of right angle and perpendicular transversal theorem.
How to prove Perpendicular and Parallel Lines?
We are given that;
Line a is parallel to line b
Line m is parallel to line n.
A) We want to prove that line a is perpendicular to n.
From the image, we see that there is a right angle sign on the opposite side of ∠1 facing m.
Now, we know that by definition of a right angle that ∠1 will also be a right angle.
Since angle 1 is a right angle, then we can say the line transversal a is perpendicular to line m.
B) We want to prove that line b is perpendicular to n.
The definition of the perpendicular transversal theorem, states that if a line is perpendicular to one of two parallel lines, then it is perpendicular to the other.
Thus, b will be perpendicular to n.

10. Fatima has 56 roses, 48 irises and 16 freesias. She wants to create bouquets using all the flowers. Calculate the highest number of similar bouquets she can make without having any flowers left over.
Answers
Answer:
16 bouquets each containing 3 roses, 3 irises and 1 freesias.
Step-by-step explanation:
If each bouquet needs at least 1 of each then she will be able to make, at most, 16 boquets with 1 freesias each because it is is the flower she has the least of. Now you will divide the other flowers across the 16 bouquets ignoring remainders. In the end there will be 8 roses left over.

Often we need to use exponents to correctly model the variation in situations:
The volume of a cylinder varies jointly with the square of its radius and its height. Its
general equation looks like V = kr’h where k= some constant number for all cylinders
and V, rand h are variables representing volume, radius and height, respectively. When
the radius is 3 cm and height is 5 cm, the cylinder has a volume of 141.3 cm. Find the
volume when the radius is 6 cm and the height is 10 cm.
Answers
Answer:
V = 1130.4 cm³
Step-by-step explanation:
Given that V varies jointly with r² and h then the equation relating them is
V = kr²h ← k is the constant of variation
To find k use the condition when r = 3 and h = 5 then V = 141.3 , then
141.3 = k × 3² × 5 = 45k ( divide both sides by 45 )
k = 3.14 ← note approximation for π
V = 3.14r²h ← equation of variation
When r = 6 and h = 10, then
V = 3.14 × 6² × 10 = 3.14 × 36 × 10 = 1130.4 cm³

Tony left the party early traveling 2 mph. 15 hours later, Pamela decided to head out and catch up with him. She ran 7 mph. How long would she have to run to catch up with him?
Answers
Pamela would have to run approximately 4.29 hours to catch up with Tony.
To determine how long Pamela would have to run to catch up with Tony, we need to find the time it takes for Pamela to cover the distance Tony covered during the 15 hours he had already been traveling.
Since Tony traveled at a constant speed of 2 mph for 15 hours, the distance he covered is given by:
Distance = Speed * Time
Distance = 2 mph * 15 hours
Distance = 30 miles
Now, Pamela wants to catch up with Tony, so she needs to cover the same distance of 30 miles. Pamela runs at a speed of 7 mph.
To find the time it takes for Pamela to cover the distance of 30 miles, we can use the formula:
Time = Distance / Speed
Time = 30 miles / 7 mph
Using division, we find:
Time ≈ 4.29 hours
Therefore, Pamela would have to run approximately 4.29 hours to catch up with Tony.

Mrs. Laurence just bought a new car for 26,304. She plans to pay her car off in 24 months. Mr. Gannon just bought a new car for 20,480 and plans to pay his car off in 20 months. How much more money a month does Mrs. Laurence pay in her car payment?
Answers
The amount of extra money a month that Mrs. Laurence pays in her car payment is $72.
How much more money does Mrs. Laurence pay each month?We can get the amount of extra amount that Mrs. Laurence pays each month when compared to Mr. Gannon by dividing the amount that they pay by the number of months they need to make these payments.
This can be done as follows:
26304 ÷ 24 = 1096
20480 ÷ 20 = 1024
1096 - 1024 - 72
So, the amount of extra money that Mrs. Laurence has to pay each month when compared to that of Mr. Gannon is $72.

The price of televisions has dropped dramatically over the last three years. Three years ago, a 32 inch television was $500. This year the tv was on sale for $199. What is the percent change?
it is due today!!! 7th honers
Answers
The percent change in the price of television from initial price $500 to final price $199 is 60.2.
What are Percentages?
The term 'per cent' means 'out of a hundred'.
Percentage is a way to define parts of a whole.
To convert fraction to a percentage, first convert fraction to decimal,
then multiply decimal value with 100, with '%' sign.
So, Percentage change = \(\frac{initial-final}{initial}\)×100%
Percentage change = { ( $500 - $199 ) / $500 } × 100%
= { $301 / $500 } × 100%
= .602 × 100%
= 60.2%
Hence, the percentage change in tv price is 60.2%.
