From the top of a 16 m tall building, the angle of depression to a car on the road is 35°. To the nearest metre, how far is the car from the base of the building?
Answers
The distance of the car from the tall building to the nearest meter is 23m.
How far is the car from the base of the building?Given the data in the question;
Angle of depression θ = 35°Height of building = 16mDistance of car from building = xWe use trigonometric ratio since the scenario forms a right angle triangle.
tanθ = opposite / adjacent
tanθ = opposite / adjacent
tan( 35° ) = 16m / x
x = 16m / tan( 35° )
x = 16m / 0.7002
x = 23m
Therefore, the distance of the car from the tall building to the nearest meter is 23m.

What is Poisson's distribution formula?In order to comprehend separate events that happen at a steady pace over the course of a specified amount of time, Poisson's distributions are frequently utilized.
Formula for Poisson's distribution:
f(x) = ((λ^x)/x!).(e^(-λ))
x = Event to be calculated for
λ = Expected number of occurrences
P(X = x) = ((λ^x)/x!).(e^(-λ))
Here λ = 3 and x = 4
P(X = 4) = (81 / 4!).(e^(-3))
P(X = 4) = (81 * e^(-3))/24
P(X = 4) = (81 * 0.049)/24
P(X = 4) = 0.1680
Hence, the probability that schools in Los Angeles will be closed for four days next year is 0.1680.

Oscar bought some markers, notebooks, and packs of sticky notes for his office. He bought the same number of markers as notebooks. He bought three more packs of sticky notes than markers and notebooks combined. He paid $1.05 for each marker, $2.25 for each notebook, and the packs of sticky notes were $1.95. How many of each kind of office supply did Oscar buy if he paid $49.05 in all?
Answers
Using a system of equations, it is found that Oscar bought 6 markers, 6 notebooks and 15 packs of sticky notes.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Number of markers.Variable y: Number of notebooks.Variable z: Number of packs of notes.He bought the same number of markers as notebooks, hence:
x = y.
He bought three more packs of sticky notes than markers and notebooks combined, hence:
z = 3 + x + y
z = 3 + 2x.
He paid $1.05 for each marker, $2.25 for each notebook, and the packs of sticky notes were $1.95. He spent $49.05 in total, hence:
1.05x + 2.25y + 1.95z = 49.05.
Then:
1.05x + 2.25x + 1.95(3 + 2x) = 49.05.
7.2x = 43.2
x = 43.2/7.2
x = 6.
The amounts are as follows:
y = 6.z = 3 + 2(6) = 15.He bought 6 markers, 6 notebooks and 15 packs of sticky notes.

What is the equation of the line that is used to show the reflection of a relation and its inverse?
help please and thank u <3
Answers
The graph and inverse of a function are reflections of each other along the line y = x.
A relation made up of ordered pairs (x, y) has as its inverse the set of all ordered pairs (y, x).
When a point is mirrored over the line y = x, the x- and y-coordinates swap places. Similarly, when a point is mirrored over the line y = -x, the x- and y-coordinates swap places and become negated.
Therefore,
The point (x, y)'s reflection over the line y = x is (y, x).
The point (x, y)'s reflection over the line y = - x is (-y, -x).
Thus, the graph and inverse of a function are reflections of each other along the line y = x.

x: total pages read3: minutes first spent9: minutes spent total1 1/2: pages read in 3 minutesto solve for x, we need to use 1 1/2/x and multiply it by x:
1 1/2/x * x
then we need to have 3/9 multiplied by x:
3/9 * x
this is equal to 1 1/2 = 3/9 * x
now you need to multiply both sides by the opposite of 3/9 = 9/3
3/2 * 9/3 = 3/9 * 9/3 * x which equals 9/2 = 4 1/2
final answer: 4 1/2

Jeff bought 3 boxes of cereal $2.99 each which comes up to $8.97,
he bought one gallon of milk for $4.98,
and 4 bananas for $0.50 each which in total is $2.00.
total amount spent: 8.97 + 4.98 + 2.00 = $15.95
We know there is a 20% off discount so what we have to do is take 20% off $15.95!
20%= $3.19
15.95 - 3.19 = 12.76
The total is now $12.76. But, Jeff payed with a $20.00 bill. Because of this, he will get $7.24 back. 12.76 + 7.24 = 20

What is the ratio of the amount of the 30% solution to the amount of 5% solution used to create the 10% solution?
Answers
The ratio comes out to be 1:4.
What is ratio?
A ratio in mathematics shows how many times one number is contained in another. For instance, if a mixture of milk and water contains eight liters of water and six liters of milk, the ratio of water to milk is eight to six. Similarly, the ratio of water to the overall amount of mixture is 8:14, while the ratio of milk to water is 6:8.
Calculating the Ratio of the Solution:
Let us assume that x is the quantity of 30% of the solution and y be that of 5% solution, then,
30% of x + 5% of y = 10% of (x + y)
0.3x + 0.05y = 0.1 (x + y)
0.3x + 0.05y = 0.1x + 0.1y
0.3x - 0.1x = 0.1y - 0.05y
0.2x = 0.05y
Thus, the required ratio is,
0.2x / 0.05y = 1
x / y = 0.05 / 0.2
x / y = 5 / 20

Two events are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin toss, which can result in either heads or tails but not both, provide a clear illustration.
A statistical term used to describe events that cannot occur concurrently is "mutually exclusive."
