Answer: This is basic trig man, So I can help you here. First thing you need is a calculator that can do sin cos and tan, ti-84 would work best. You need to use the sin cos and tan formulas to find the edge lengths of the side. heres a helppful tip to remeber the proper way to use the formulas. SOH-CAH-TOA or sin(angle measure)= Opposite side to that angle measure divided by the hypotenuse cos(angle measure)= adjacent side (the side next to the angle) divided by the hypotenuse. and TOA or Tan(angle measure)=Opposite divided by adjacent.

4) A zoologist was checking the weights of three gorillas. Gorilla A weighed 559 pounds, gorilla B weighed 827 pounds and gorilla C weighed 130 pounds. What is the combined weight of all three gorillas?
Answers
Answer:
1,516 pounds
Step-by-step explanation:
Gorilla A weighed = 559 pounds Gorilla B weighed = 827 pounds Gorilla C weighed = 130 pounds
Total weight of the gorillas = gorilla A + gorilla B + gorilla C
= 559 pounds + 827 pounds + 130 pounds
= 1,516 pounds
Total weight of the gorillas = 1,516 pounds

In the △ABC, the height AN = 24 in, BN = 18 in, AC = 40 in. Find AB and BC. Consider all possible cases. Case 1 : N∈BC, AB = __, BC = __ Case 2 : B∈NC, AB = __, BC = __ Case 3 : C∈BN, AB = __, BC = __
Answers
Case 1: N ∈ BC, AB = 32 in and BC = 42 in.
Case 2: B ∈ NC, AB = 22 in and BC = 32 in.
Case 3: C ∈ BN, AB = 42 in and BC = 32 in.
Case 1: N ∈ BC
In this case, consider triangle ABC as a right triangle with right angle at B.
AN = 24 in
BN = 18 in
AC = 40 in
Using the Pythagorean theorem in triangle ABC
AB = √(AC² - AN²)
= √(40² - 24²)
= √(1600 - 576)
= √1024
= 32 in
or, BC = BN + NC
= BN + AN
= 18 + 24
= 42 in
Therefore, in Case 1: N ∈ BC, AB = 32 in and BC = 42 in.
Case 2: B ∈ NC
In this case, consider triangle ABC as a right triangle with right angle at C.
AN = 24 in
BN = 18 in
AC = 40 in
Using the Pythagorean theorem in triangle ABC, we can find the lengths of AB and BC:
AB = √(AC² - AN²)
= √(40² - 24²)
= √(1600 - 576)
= √1024
= 32 in
or, BC = AC - BC
= 40 - BN
= 40 - 18
= 22 in
Therefore, in Case 2: B ∈ NC, AB = 22 in and BC = 32 in.
Case 3: C ∈ BN
In this case, we can consider triangle ABC as a right triangle with right angle at A. We have the following information:
AN = 24 in
BN = 18 in
AC = 40 in
Using the Pythagorean theorem in triangle ABC,
AB = AN + NC
= AN + BN
= 24 + 18
= 42 in
Therefore, in Case 3: C ∈ BN, AB = 42 in and BC = 32 in.

A new test is developed to test for organic matter in soil samples, giving "positive" or "negative" results to indicate that a sample does or does not contain organic matter.
For a soil sample that contains organic matter, the test will give a positive result 95% of the time and a negative result (false negative) 5% of the time. For a soil sample that does not contain organic matter, the test will give a positive result (false positive) 20% of the time and a negative result 80% of the time.
A study included a population of 1,000 soil samples, and 70% of those studied where known to contain organic matter.
Fill in the missing values in the table and statement below. If necessary, round the percentage to one decimal place.

If a soil sample test gives a positive result, it is
% likely that the soil sample contains organic matter.
Answers
Answer:

91%
Step-by-step explanation:
If a soil sample test gives a positive result, it is **91.7%** likely that the soil sample contains organic matter.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
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
We are given that;
Positive results= 95%
Negative results= 5%
Now,
Positive result = 700 * 0.95 = 665
Negative result = 700 * 0.05 = 35
Similarly, for the soil samples that do not contain organic matter, we know that 20% of them will give a positive result and 80% will give a negative result. So, we can multiply 300 by 0.2 and 0.8 to get:
Positive result = 300 * 0.2 = 60
Negative result = 300 * 0.8 = 240
To fill in the missing value in the statement, we can use Bayes' theorem, which states that:
P(A|B) = P(B|A) * P(A) / P(B)
So, we have:
P(contains organic matter | positive result) = P(positive result | contains organic matter) * P(contains organic matter) / P(positive result)
P(positive result) = P(positive result | contains organic matter) * P(contains organic matter) + P(positive result | does not contain organic matter) * P(does not contain organic matter)
P(positive result) = 0.95 * 0.7 + 0.2 * 0.3
P(positive result) = 0.665 + 0.06
P(positive result) = 0.725
Plugging these values into Bayes' theorem, we get:
P(contains organic matter | positive result) = (0.95 * 0.7) / (0.725)
P(contains organic matter | positive result) = (0.665) / (0.725)
P(contains organic matter | positive result) = 0.9172
Therefore, by probability the answer will be 91.7%

Step-by-step explanation:
2 x 4/6 as a multiplication of a whole number and a unit fraction.
First off lets find 2 x 4/6
2 x 4/6 = 8 /6
Ok, now lets go back to the original equation.
2 x 4/6
divide 4/6 by 4 to get a unit fraction
A x 1/6
Divide 8/6 by 1/6 = 8
Or you can do A (previously known as 2) by 4 because we divide 4/6 by 4
A = 2x4 = 8
8 x 1/6 = 8/6

Q1. Three types of coffee beans, A, B and C, are blended in the ratio 3: 5:7 to make a bag of coffee
powder. Given that the bag contains 45 kg of coffee powder, find the mass coffee beans A in the
mixture?
Answers
Answer:
Mass of coffee A beans = 9 kg
Step-by-step explanation:
Coffee A = 3
Coffee B = 5
Coffee C = 7
A : B : C = 3 : 5 : 7
Total ratio = 15
Total mass of the bag = 45 kg
find the mass coffee beans A in the mixture?
Mass of coffee A beans = ratio of coffee A / total ratio × total mass of the bag
= 3/15 × 45
= 1/5 × 45
= (1 * 45)/5
= 45/5
= 9 kg
Mass of coffee A beans = 9 kg
Mass of coffee B beans = ratio of coffee B / total ratio × total mass of the bag
= 5/15 × 45
= 1/3 × 45
= 45/3
= 15 kg
Mass of coffee C beans = ratio of coffee C / total ratio × total mass of the bag
= 7/15 × 45
= (7*45)/15
= 315/15
= 21 kg
