Step-by-step explanation:
I will assume that you're trying to solve for "x".
For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.
Now, 131 = 5x+1
-1 -1
130 = 5x
/5 /5
Now, we isolate the x to get x=26.
Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.
Now, combine the like terms to get 11x+15=180 so we now isolate x.
-15 -15
11x=165
/11 /11
x=15
Now, try the rest and set the terms to 180.
5x+1+8+4x=180
2x+1+x-10=180
6+x+5x=180
x+2+153=180(This is similar to #1)

Katarina asks Dacia how she can you derive the formula r= x2+y2. Which of Dacia's replies are correct?
Answers
Options A and B are correct. If Katarina asks Dacia how she can derive the formula r= x²+y², then the following statements should be Dacia's reply.
Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'rr is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1Given the equation by Katarina expressed as:
r = √x²+y²
One of the ways Katarina can derive the equation is to use the Pythagoras theorem which states that the sum of the square of the hypotenuse is equal to the sum of the other two sides. Let:
r be the length of the hypotenuse
x and y be the other two sides
According to the theorem:
r² = x² + y²
Take the square root of both sides
√r² = √x² + y²
r = √x² + y²
Also, Katarina can use the trigonometry identity. According to a right triangle where:
sinθ = y/r
Cosθ = x/r
According to trigonometry identity, sin²θ+cos²θ = 1
(y/r)² + (x/r)² = 1
y²/r² + x²/r² = 1
(y²+x²)/r² = 1
y²+x² = r²
Swap
r²=y²+x²
This shows that the first two options are correct.
Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'r
r is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1

According to data, as education level increases the unemployment rate decreases. This is an example of
what type of correlation?
Answers
As education level increases the unemployment rate decreases this is a negative linear type correlation.
What are the main types of correlation ?There are three main types of correlations they are positive linear correlation where both the variables related to each other increase or decrease simultaneously.
In negative linear correlation between two variables if one variable is increasing the other starts to decrease and vice versa and the third type of correlation is where there is no correlation increase and decrease happen in random way that is quite difficult to form in terms of numerical form or graphing them.
According to the given statement as education level increases the unemployment rate decreases.
This is an example of negative linear correlation as one variable increases the other related to it decreases.
Increase in education level decreases unemployment as with higher education people learn new skills,they become more aware of their surroundings and most importantly education teaches us to think logically these are the things that a co-operate world wants.

Her jump rope Ella can make 17 jumps in 15 second.at this rate how make jumps can she make in20 minute?
Answers
Answer:
1360
Step-by-step explanation:
there are 1200 seconds in 20 minutes. if Ella can do 17 jumps in 15 seconds, you would divide 1200 by 15 (which equals 80) because that would be the number of 15 seconds in 20 minutes. then you would divide 80 by 17, which gives you your final answer of 1360 jumps in 20 minutes.

Kaylee has a 7/12 yard piece of lace that she is using to make doll dresses. She
needs 1/8 yard for each dress. Which expression can be used to show how
many dresses she can make from the lace?
Answers
The expression that can be used to show how many dresses she can make from the lace is [tex]\frac{7}{12}[/tex] ÷[tex]\frac{1}{8}[/tex]
In order to determine how many dresses can be made from the lace, divide the yards of the lace by how many yards are needed to make the dress
Number of dresses that can be made = [tex]\frac{7}{12}[/tex] ÷ [tex]\frac{1}{8}[/tex]
Solving this equation, 4 dresses can be made from the lace
7/12 x 8/1 = 4.67 dresses

10. The Earth’s escape speed (the speed you need to get away forever) is about 25,000 miles per hour. Escape speed depends on the gravity of the object trying to hold the spacecraft from escaping. Based on your understanding of gravity, how will the escape speed from the Moon compare to the escape speed from Earth?
a. The Moon’s escape speed will be greater than Earth’s
b. The Moon’s escape speed will be smaller than Earth’s
c. The Moon’s escape speed will be exactly the same as Earth’s
d. The Moon’s escape speed will change depending on whether it’s a crescent Moon or a full Moon
e. The Moon’s escape speed will be balanced by the Earth being so close and it will be zero
Answers
Gravity on the moon is less than on Earth, because the mass of the moon is small than then mass of Earth.
Since gravity on the moon is less and escape speed depends on that gravity,
=> the moon’s escape speed will be smaller than Earth’s.
