HELPPP!! which of the following could be the ratio between the lengths of two legs of a 30,60,90 triangle
check all that apply:
whoever gives me the correct answer gets brianliest
Answer:
[tex]\sqrt{3}:3\\1:\sqrt{3}[/tex]
Step-by-step explanation:
Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
The tangent ratio is defined as:
[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
The cotangent ratio is defined as:
[tex]\displaystyle \cot\theta=\frac{\text{adjacent leg}}{\text{opposite leg}}[/tex]
As shown above, the tangent and the cotangent are the ratios of the two legs in any possible order.
If the triangle has angles of 30°, 60°, and 90°, then we can take one of the acute angles and find the tangent and cotangent to know the required ratios:
Let's take for example the 30° angle:
[tex]\displaystyle \text{ratio of legs: }\tan 30^\circ=\frac{\sqrt{3}}{3}[/tex]
[tex]\displaystyle \text{ratio of legs: }\cot 30^\circ=\sqrt{3}[/tex]
Thus the possible ratios from the list are:
[tex]\sqrt{3}:3\\1:\sqrt{3}[/tex]
The reciprocals of those ratios are also applicable

One tree can produce 175 avocados. The avocados are packed in boxes of 24. How many boxes are needed?
Answer:
8 boxes
Step-by-step explanation:
Divide 175 by 24 since you have 175 avocados and 24 can be put in each box. This gives you 7.29166666667. You have to round up to get 8.
Answer:
8 boxes would be needed
Step-by-step explanation:
175/24 = 7 with a remainder of 7 and you cannot just leave out those 7 avocados, they will be lonely so therefor you will need another box and 7+1=8

Choose the correct answer to 8,817/43.
25 R2
205
205 R2
204 R45
Answer:
204 R45
Step-by-step explanation:
Answer: The answer will be 205 R2
Step-by-step explanation:
I know this because the steps to dividing are:
D - Divide
M - Multiply
S - Subtract
B - base(total)
If you do all of those steps then you'll get 205 R2
R = remainder(left overs)
So, the answer will be 205 R2
How can you use the distributive property to rewrite a quadratic expression in order to reveal its factors and zeros
Answer:
(x-rooot1)(x-root2)
Step-by-step explanation:
a quadratic ax²+bx+c=0 can be factor as those 2 pharanthesis
(x-rooot1) (x-root2)=0
and you can find the roots by making each parenthesis equal to 0 because of the zero product rule
x-root1 = 0, x=root1
x-root2 =0, x=root2

EFGH is a parallelogram. Find the given side length. Please help
Answer:
EF=35
EG=22
Step-by-step explanation:
EF
7y-14=2y+21
5y=35
y=7
EF=7(7)-14=49-14=35
EG
15x+7=12x+10
3x=3
x=1
EG=15(1)+7=15+7=22
Answer:
(a). 35 units ; (b). 44 units
Step-by-step explanation:
(a). 7y - 14 = 2y + 21 ⇒ y = 7
EF = 7(7) - 14 = 35 units
(b). EJ = JG
15x + 7 = 12x + 10 ⇒ x = 1
EG = 2 × (15(1) + 7) = 44 units
What two integers are between the square root of 38
Answer: 38 is not a perfect square.
square root of 38 is 6.164
Step-by-step explanation:
it is between 6 and 7
Answer:
6 and 7
Step-by-step explanation:
Choose the closest perfect squares either side of 38, that is
36 < 38 < 49 , then
[tex]\sqrt{36}[/tex] < [tex]\sqrt{38}[/tex] < [tex]\sqrt{49}[/tex] , that is
6 < [tex]\sqrt{38}[/tex] < 7

There are 3 cubes in a bag. Two are red and one is green. Sammy randomly selected a cube, put it back and selected another cube. What is the probability of getting to reds?
Answer: 2/3
Step-by-step explanation:
Number of red cubes = 2
Number of green cubes = 1
Total cubes in the bag = 3
The question relates to a probability with replacement. The probability of getting two reds will be the probability of picking red the first time multiplied by the probability of picking red the second time. This will be:
= 2/3 × 2/3
= 2/3

Answer:
1. 1/2, 2. 2, 3. 1/-3, 4. -2
Step-by-step explanation:
1) I know that the equation for slope is y2-y1/x2-x1. For number one I first found two points of the graph which is (0,3) and (2,4) (not sure if I see it correctly, its kind of blurry). I decided that (0,3) would be my y1 and x1 and (2,4) will be my y2 and x2. I later plugged the number in the equation and got 4-3/2-0 which the answer turns out to be 1/2.
2) For the rest of the questions it is kinda the same business as question 1. For question two I chose two points out of the table which wrer (-1, -12) and (1,-8) and plugged them into the equation and got -8-(-12)/1-(-1) which the answer turns out to be 2.
3) similar to question 2. The two points(2,-6) and (-4,-3) are given to you. so I plugged them in again and got -3-(-6)/-4-2 which the answer turns out to be 3/-6 into 1/-3.
4) Same with question 1 find two points of the graph. I chose (0,3) and (1,1) (again might not be accurate it's kind of blurry) I plugged them into the equation again and got 1-3/1-0 which equals -2.
Just always remember y2-y1/x2-x1=m is the equation for slope.
(m is the variable for slope)

Given the relation y = –4x2 – 8, if the input is 2, what is the output?
Answer:
y = -24
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
y = -4x² - 8
x = 2
Step 2: Solve
Substitute: y = -4(2)² - 8Evaluate: y = -4(4) - 8Multiply: y = -16 - 8Subtract: y = -24Answer:
Given, input (x) is 2,
[tex]y = -4x^2 - 8\\y = -4(2)^2 - 8\\y = -4(4) - 8\\y = -16 - 8\\y = -24[/tex]
Output (y) is 24
