The value of m∠R is 106°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
ΔRST
m∠R = 6x + 10
m∠S = 2x + 5
m∠T = 3x - 11
Now,
The sum of the angles is 180 degrees.
6x + 10 + 2x + 5 + 3x - 11 = 180
11x + 4 = 180
11x = 180 - 4
11x = 176
x = 176/11
x = 16
Now,
The value of m∠R.
= 6x + 10

Plants, like the Monstera Plant, in HELP IM ON A TIME LIMIT!!!!
the rainforest have long, grooved leaves to drop water to the forest
floor. The excessive water that falls in the rainforest could lead to mold, so the leaves adapted to
have “drip tips” that allow the water to run off of the leaves.
What type of adaptations are these? Compare and contrast the adaptations of the Toucan and
Monstera Plants of the rainforest. Your answer should be 3–4 sentences long.
Answers
Answer:
They have large leaves with holes in them that the Toucan can use to reach the fruit inside. The Toucan's beak is also used to break open hard-shelled fruits, such as coconuts. The Toucan's beak is also used for defence against predators, as it can be used to peck and jab at them. The adaptations of the rainforest plants are examples of convergent evolution. Both the Toucan and Monstera Plants have adapted to their environment in order to survive. The Toucan has a large beak that helps it to reach fruit in the canopy, while the Monstera Plant has long, grooved leaves with drip tips that allow water to run off and prevent mould. Both adaptations are beneficial for the survival of the species in the rainforest.

5d + 5c = 225 equation 2
subtract equation 2 from 1

A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers, with the same combination of sixth- and seventh-grade students in each group. She wants to form as many groups as possible. If the largest group was formed, how many students of each grade level would be in each group?
Answers
Answer:
The music director can form a total of 15 groups
6 Sixth grade students per group
5 Seventh grade students per group
Step-by-step explanation:
Sixth grade students = 90
Seventh grade students = 75
Find the highest common factor of 75 and 90
90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.
75 = 1, 3, 5, 15, 25, 75
The highest common factor of 75 and 90 is 15
Therefore, the music director can form a total of 15 groups
Sixth grade students per group = 90 / 15
= 6 Sixth grade students per group
Seventh grade students per group = 75 / 15
= 5 Seventh grade students per group
Sabrina is tracking the growth rates of a colony of ants and of a bee hive. From her research, she has developed a function to represent the population growth of each type of insect, where y represents the population and x represents the number of weeks since Sabrina began her research.
Which insect population is growing at a faster rate?
The ant colony is growing at a faster rate. It will multiply by 3.8 each week while the bee hive will add 3.8 each week.
The bee hive is growing at a faster rate. It will multiply by 3.8 each week while the ant colony will add 3.8 each week.
The ant colony is growing at a faster rate. It will add 3.8 each week while the bee hive will subtract 3.8 each week.
The bee hive is growing at a faster rate. It will add 3.8 each week while the ant colony will divide by 3.8 each week.
Answers
The insect population that is growing at a faster rate is; A. The ant colony is growing at a faster rate. It will multiply by 3.8 each week while the bee hive will add 3.8 each week.
How to interpret Exponential functions?From the graph attached, we see that he ants have an exponential growth because the equation is; y = 3.8ˣ.
Now after each week, the colony multiplies by 3.8.
First week is; y = 3.8¹ = 3.8
Second week would have; y = 3.8² = 14.44.
Third week would have; y = 3.8³ = 54.9.
However, the second graph which is a linear function shows that bee hive growth adds 3.8 after each week. This means that;
The second week would have; 2 * 3.8 = 7.6
The 3rd week would have; 3 * 3.6 = 11.4.
Thus, we conclude that the ant colony is growing faster

We have three points that represent the vertices of the triangle

Step-by-step explanation:

D=64+36=100
\(x_{1} =\frac{-8+10}{2} =1\)

so, smaller answer x=-9
larger answer x=1
Answer:
x = - 9, x = 1
Step-by-step explanation:
Given
x² + 8x + 14 = 23 ( subtract 23 from both sides )
x² + 8x - 9 = 0 ← in standard form
(x + 9)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9 ← smaller answer
x - 1 = 0 ⇒ x = 1 ← larger answer

In foggy, rainy, and sunny conditions, 1/5, 1/12, and 1/27 of the accidents result in death, respectively. Sunny conditions occur 66% of the time, while rainy and foggy conditions each occur 17% of the time.

P= Enter your answer in accordance to the question statementEnter your answer in accordance to the question statement
Answers
The conditional probability that the accident occurred in foggy conditions given that there were no deaths is 0.089.
To solve this problem, we can use Bayes' theorem, which states that the conditional probability of an event A given event B is equal to the probability of event B given event A, multiplied by the prior probability of event A, divided by the overall probability of event B.
Let F, R, and S denote the events that the accident occurred in foggy, rainy, and sunny conditions, respectively, and let D denote the event that there were no deaths. Then we have:
P(F | D) = P(D | F) * P(F) / P(D)where P(D | F) is the probability of no deaths given that the accident occurred in foggy conditions, which is 4/5. P(F) is the prior probability of the accident occurring in foggy conditions, which is 0.17. P(D) is the overall probability of no deaths, which we can calculate using the law of total probability:
P(D) = P(D | F) * P(F) + P(D | R) * P(R) + P(D | S) * P(S)
= (4/5 * 0.17) + (11/12 * 0.17) + (26/27 * 0.66)
= 0.739
Plugging in these values, we get:
P(F | D) = (4/5 * 0.17) / 0.739
= 0.089 (rounded to three decimal places)
Therefore, the conditional probability that the accident occurred in foggy conditions given that there were no deaths is 0.089.

A box contains some green and yellow counters. 7/9of the box is green counters. Are 24 yellow counters. There How many green counters are there?
Answers
If 7/9 of the box is green counters, and there are 24 yellow counters in the box, then there are 84 green counters .
Let's assume that the total number of counters in the box is x.
We are given that 7/9 of the box is filled with green counters, which means that the remaining 2/9 of the box must be filled with yellow counters. We are also given that there are 24 yellow counters in the box.
We can set up an equation to represent the relationship between the number of yellow counters and the total number of counters:
2/9 x = 24
To solve for x, we can multiply both sides of the equation by the reciprocal of 2/9, which is 9/2:
(2/9) x * (9/2) = 24 * (9/2)
x = 108
This means that there are a total of 108 counters in the box. To find out how many of these are green counters, we can use the fact that 7/9 of the box is filled with green counters:
(7/9) * 108 = 84

the general form of solution to an = 5a n-2 -4an-4 is
Answers
The general form of solution is:
an = c1(√6)^n + c2(-2)^n, where c1 and c2 are constants determined by the initial conditions.
To find the general form of solution to an = 5a n-2 -4an-4, we can use the method of characteristic equation.
Assuming the solution is in the form of an = r^n, we can substitute it into the equation to get:
r^n = 5r^(n-2) - 4r^(n-4)
Dividing both sides by r^(n-4), we get:
r^4 = 5r^2 - 4
This is the characteristic equation. Solving for r, we get:
r = ±√(5 ± 1)
There are four roots to this equation, but only two of them are distinct. Let's call them r1 and r2:
r1 = √(5 + 1) = √6
r2 = -√(5 - 1) = -√4 = -2
Therefore, the general form of solution is:
an = c1(√6)^n + c2(-2)^n
where c1 and c2 are constants determined by the initial conditions.
