Answer:
120, remember the angles have to add up to 180
Step-by-step explanation:
Answer:
60 because 30+30=60 and a triangle is 180° so 180-60= 120 and it's a line so 180-120=60 ifykyk

In a video game, a guppy that escapes a net turns into three goldfish. Each goldfish can turn into two betta fish. Each betta fish can turn into two angelfish. Complete the diagram and write the number of fish at each stage. Write and evaluate an expression for the number of angelfish that can be formed from one guppy
Answers
Answer: 1 guppy = 3 goldfish
1 goldfish = 2 betta fish.....so 3 goldfish = (3 * 2) = 6 betta fish
1 betta fish = 2 angel fish....so 6 beta fish = (6 * 2) = 12 angel fish
so the number of angelfish that can be formed by 1 guppy is 12 angelfish

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of −0.91 is calculated. What would this imply about the football team winning at home?
1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
2.The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.
3.The scatter plot would not be represented by a line of best fit with a negative slope. There is a weak correlation between the football team playing at home and winning.
4. There is no causation and almost no correlation between the football team playing at home and winning.
Answers
Correlation coefficients are used to solve this question, leading to the following answer:
1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
-----------------------------------
Correlation coefficients:
They measure the relationship between variables, the closer |r| is to 1, the stronger the relationship is.
If the coefficient is positive, there is a positive relationship(both variables change in the same direction)If the coefficient is negative, there is a negative relationship(the variables change in opposite directions).-----------------------------------
In this question:
r = -0.91
Negative, so opposite directions, which can be explained as for example, the more the team travels(plays away games), the less games it wins.|r| = 0.91, which is quite close to 1, so a significant relationship.Negative relation means that the scatter plot would be represented by a straight line with a negative slope, and the correct answer is:1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.

Answer:
D
Step-by-step explanation:
Two lines are parallel if they have the same slope.
the given equation is in the form
y=mx+b
where
m=-5/2
b=-7
m is the slope. You can see this by noting that if you increase x by 1 you increase y by m.
So, in this case, you are looking for a line with slope of -5/2.
You can solve each of the choice equations for y to see which one has the right slope.
A: y=(2/5)x-6 no good
B: y=-(2/5)x-1 no good
C: y=(5/2)x-4 no good
D: y=-(5/2)x-4 GOOD

Given[tex]\sqrt[3]{8+3\sqrt{21} } + \sqrt[3]{8-3\sqrt{21} }[/tex]To find The value of the expressionSolutionLet's rewrite the given as:
[tex]\sqrt[3]{3\sqrt{21} + 8} - \sqrt[3]{3\sqrt{21} - 8}[/tex]Let the value is m and the expressions under 3rd roots are a and b, then we have
a = 3√21 + 8, b = 3√21 - 8m = ∛a - ∛bCube the both sides:
m³ = (∛a - ∛b)³m³ = a - b - 3[tex]\sqrt[3]{a^2b}[/tex] + 3[tex]\sqrt[3]{ab^2}[/tex]Simplify in bits:
a - b = 3√21 + 8 - 3√21 + 8 = 16ab = (3√21 + 8)(3√21 - 8) = 9*21 - 64 = 125∛ab = ∛125 = 5So the expression becomes:
m³ = 16 - 3[tex]\sqrt[3]{125a} + \sqrt[3]{125b}[/tex]m³ = 16 - 15∛a + 15∛bm³ = 16 - 15(∛a - ∛b)m³ = 16 - 15mSolve for m:
m³ + 15m - 16 = 0m³ - 1 + 15m - 15 = 0(m - 1)(m² + m + 1) + 15(m - 1) = 0(m - 1)(m² + m + 16) = 0m - 1 = 0, m² + m + 16 = 0m = 1 is the only real root, the quadratic equation has no real rootsThe answer is 1

A tea shop brewed 8 7/8 pitchers of chamomile tea, of which it sold 2 3/5 pitchers. How many pitchers remained unsold?
Answers
Answer:6 11/40
Step-by-step explanation: You can change your units to decimals or to fractions of equal value. Decimals are easier for this so 8 7/8= 8.875 and 2 3/5 =2.6. Then subtract: 8.875-2.6= 6.275 You can now convert back to a fraction by simplifying the .275 into 11 by dividing by 25 and 1000 into 40 by dividing by 25. 6+11/40= 6 11/40 tea left
Answer:
6 11/40
Step-by-step explanation:
First you have to convert the fractions into improper fractions, where 8 7/8 would turn into 71/8 and 2 3/5 would turn into 13/5. Then you have to find a common denominator which would be 40, so you get 355/40 and 104/40. Then to find the remaining amount, you have to subtract 104/40 from the 355/40, so 355/40 - 104/40, which equals 251/40. This turns into 6 11/40, which can't be simplified any further. Hope this helps :)

Step-by-step explanation:
1. Approach
First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.
2. Convert the unit of measurement
The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].
[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]
3. Find the area of the room
Now multiply the length by the width to find the area of the room.

Alvin's age is three times Elga's age. The sum of their ages is 104. What is Elga's age?
Answers
Answer: Alvin is 78, Elga is 26
Step-by-step explanation:
Let's first start by naming the variables:
a = Alvin's age
e = Elga's age
a = 3e
a + e = 104
substitute a (in the second equation) as 3e
3e + e = 104
4e = 104
e = 26
Substitute e as 26 into either equation
a = 3(26)
a = 78
