Answer: 6 and 8
Step-by-step explanation: A right triangle is a triangle with one angle that measures 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. In this case, the hypotenuse is 10cm long.
If one angle of the triangle is 40 degrees, then the other angle must be 90-40 = 50 degrees. The remaining two angles of a triangle must add up to 180 degrees, so the third angle is 180-40-50 = 90 degrees. This means that the triangle is a right triangle, and we can use the Pythagorean theorem to find the lengths of the legs.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. In this case, we have a2 + b2 = c2, where a and b are the lengths of the legs and c is the length of the hypotenuse.
Substituting the values from the problem, we have a2 + b2 = 102, which simplifies to a2 + b2 = 100. Since we don't know the values of a and b, we can't solve for them directly. However, we can use the fact that the angle opposite the longer leg is 50 degrees, and the angle opposite the shorter leg is 40 degrees. This means that the longer leg is the opposite side of the 50-degree angle, and the shorter leg is the opposite side of the 40-degree angle.
Since the longer leg is opposite the 50-degree angle, and the shorter leg is opposite the 40-degree angle, we can use the tangent function to find the ratio of the lengths of the legs. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side, so we have tangent(50 degrees) = opposite side / adjacent side = a / b, and tangent(40 degrees) = opposite side / adjacent side = b / a.
Solving for a and b, we have a = b * tangent(50 degrees) and b = a * tangent(40 degrees). Since the legs are the opposite sides of the 40- and 50-degree angles, we can substitute the values from the problem to get a = b * tangent(50 degrees) = 100 * tangent(50 degrees) and b = a * tangent(40 degrees) = 100 * tangent(40 degrees).
To find the values of tangent(50 degrees) and tangent(40 degrees), we can use a calculator or look up the values in a table of trigonometric functions. We find that tangent(50 degrees) = 1.191753592594, and tangent(40 degrees) = 0.839099631177. Substituting these values into the equations for a and b, we have a = 100 * 1.191753592594 = 119.1753592594 and b = 100 * 0.839099631177 = 83.9099631177.
Rounding to the nearest whole number, we have a = 119 and b = 84. The lengths of the legs of the triangle are therefore 6 and 8.
You ask your best friend to lend you 200 to buy your favourite toy. She says she can lend you the money
only if you give her an extra 2 for every month that passes before you return it.
What is the annual rate of interest she is charging you?
The annual rate of interest she is charging you is 12%.
Given that, you ask your best friend to lend you $200 to buy your favorite toy.
What is the rate of interest?An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
Here,
Extra money per month =$2
Extra money per year = $2×12
Extra money per two year = 2×2×12 = 4×12 = $48
Money lend = $200
Money given after two years = $(200+48) = $248
Now, the rate of interest can be find using SI=(P×R×T)/100
48= (200×R×2)/100
⇒ 48= 4R
⇒ R=12%
Hence, the annual rate of interest she is charging you is 12%.

Can someone help me with this please I really am confused
Answer:
56
Step-by-step explanation:
When you subtract a negative number. Just consider it addition.
So, 40+16
It's very simple from there.
Answer:
56!
Step-by-step explanation:
The question is 40 minus negative 16.
When you subtract a negative, it's the same as adding.
So 40 - (-16) is the same as 40 + 16, which equals 56.
Example:
If you have 3 apples, and you remove negative 3 apples from 3, now you have 6.
So, 3 - (-3) = 6.

Hobi mows two lawns. The first lawn is 7 feet long and 3 feet wide.
The area of the second lawn is 4 times as big but has the same
width as the first.
What is the length of the second lawn?
Answer:
28 feet long
Step-by-step explanation:
we find the area of the first lawn using recent angle formula (l)(w)=a
(7)(3)

Now we multiply this by 4 since the second lawn is four times it
21x4

/w. /w
a/w=l
Now we fill in this formula

what is the probability that when a pair of dice are rolled, either (at least) one dice shows a 5, or that the dice sum to 8?
Observing the cases provided with the formula of probability and implementing it with OR rule , The answer is 0.22.
What do you mean by probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
What is sample space?All potential results make up the sample space of a random experiment. A subset of the sample space is an event connected to a random experiment. Any outcome's probability is a value between 0 and 1. The sum of all the outcomes' probabilities is one.
Probability that dice rolled shows a 5 once = 1/36
Probability that dice rolled shows a 5 twice = 2/36
Probability that the sum is 8 = 5/36
Total probability = 1/36 + 2/36 + 5/36 = 0.22

Wesley is going backpacking in a couple of days and is buying trail mix for the trip. The amount of trail mix he will bring depends on how long he plans to backpack. a = the amount of trail mix Wesley will bring /= the length of the backpacking trip Which of the variables is independent and which is dependent?
Answer: In this scenario, the length of the backpacking trip is the independent variable and the amount of trail mix Wesley will bring is the dependent variable.
The independent variable is the variable that is being changed or controlled in an experiment or study. In this case, the length of the backpacking trip is the independent variable because it is being determined by Wesley and is not influenced by any other factor.
The dependent variable is the variable that is being measured or observed in an experiment or study. In this case, the amount of trail mix Wesley will bring is the dependent variable because it depends on the length of the backpacking trip. Wesley's decision on how much trail mix to bring will be influenced by how long he plans to go backpacking.

In right triangle ABC, m∠C=3y-10, m∠B=y+40, and m∠A=90 What is the measure of ∠C?
The unknown angle of the right angle triangle is as follows:
∠C = 35°How to find the angle of a right angle triangle?A right angle triangle is a triangle that has one of its angles as 90 degrees. The sides of a right angle triangle can be named base on the position of the angles. The sides includes hypotenuse side, opposite side and adjacent side.
The sum of angles in a right angle triangle is 180 degrees. Therefore, let's find the ∠C in the triangle ABC.
Therefore,
180 = ∠A + ∠B + ∠C
m ∠B = y + 40
m ∠C = 3y - 10
m ∠A = 90°
Hence,
180 = 3y - 10 + y + 40 + 90
180 = 4y + 120
180 - 120 = 4y
y = 60 / 4
y = 15
Hence,
m ∠C = 3(15) - 10
m ∠C = 45 - 10

FYI : one way of explaining the theorem is : we could see this as 2 projections originating from E at the same angle but onto a tilted projection screen.
the length on the projection screen (HD or GD) is directly related to the distance from the projection point to the end of the tilted projection : ED or EG. and so the ratios of both projections must be equal (due to the equal angle).
so, in our case
35/56 = (x + 4)/44.8

The probability that a student is chosen randomly from the class has a cat or a dog is 26/29.
What is the probability?It is based on the probabilities that something could happen. The theory of probability primarily relies on the justification for probability. A coin is tossed, for instance, and the theoretical likelihood of randomly receiving a head is 1 in 2.
explanation:
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
The total strength of the class is 29
The probability that a student is chosen randomly from the class has a cat or a dog = Number of favorable outcomes / total number of outcomes
