Given:
b= 6cm
c= 10cm
To find: Side a
Solution:
By Pythagoras’ theorem:
a^2+b^2=c^2
a^2+6^2=10^2
a^2+36=100
a^2=100-36
a^2=64
a= root of 64
a=8cm
Answer:
d. 8
Step-by-step explanation:
by Pythagoras theorem:
(Hypo)² = (Perp)² + (Base)²
(Perp)²= (Hypo)² - (Base)²
= 10 × 10 - 6 × 6
= 100 -36
=(underroot) 64
= 8

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

A number that would lie between -2.15 and -2.16 on the number line are 2.151.
What is a number line?Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.
There are some possibilities would include the following:
2.151, 2.152, 2.153, 2.154, 2.155, 2.156, 2.157, 2.158, 2.159
therefore, the numbers that are between 2.15 and 2.16 are 2.151.

Things I am good at
Almost everyone is kind at least one sport. The one competition that I am good at is basketball. In my school, almost everyone had an obsession with the sport, and so did I. Every game period, my teacher would make us play basketball, along with other games. Over the years, the way I played basketball improved, and while learning the game, I discovered other lessons as well. One of the lessons I’ve learned is how to play in a team. When you play in a group, you depend on each other for winning.
I have always been energetic and lively. While many people feel awkward and weird, making me friends, I have no problems with making new friends. I can talk to everyone quickly and know them.

In the below figure angle abc is 69 degree, angle acb is 31 degree so find the angle bdc
Answers
Answer:
[tex]\angle BDC=80^{\circ}[/tex]
Step-by-step explanation:
We are given that
[tex]\angle ABC=69^{\circ}[/tex]
[tex]\angle ACB=31^{\circ}[/tex]
We have to find the angle BDC.
In triangle ABC
Sum of interior angles of triangle=180 degrees
[tex]\angle ABC+\angle ACB+\angle BAC=180^{\circ}[/tex]
[tex]69+31+\angle BAC=180[/tex]
[tex]100+\angle BAC=180[/tex]
[tex]\angle BAC=180-100[/tex]
[tex]\angle BAC=80^{\circ}[/tex]
[tex]\angle BAC=\angle BDC=80{\circ}[/tex]

Answers
Answer:
A^2 + B^2 = C^2
Step-by-step explanation:
Your welcome!
Answer:
x = 13
Step-by-step explanation:
In order to solve this you need to know the Pythagorean theorem:
a^2 + b^2 = c^2
a - 1 side
b - 2nd side
c - hypoteneuse
Step 1: Find the missing side of the triangles
** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**
Solve:
17^2 + b^2 = 19^2
289 + b^2 = 361
361 - 289 = 72
√72 = √b^2
8.5 = b (approximately, to the tenth)
Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:
8.5 + 8.5 = 17
Then you subtract it from the base value: 31
31 - 17 = 13
Therefore, x = 13, as that is the remaining of the base.

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.
