The kingdom of Arendelle is trying to decide who to send to the regional track meet. Anna, Elsa, and Olaf competed in the long jump and their 6 jumps are shown below (in meters). Kristoff says that Olaf has the longest average, so he should be sent to the track meet. Do you agree or disagree? Why?

Answer:

C

Step-by-step explanation:

Because C line has the straighest edge and it's the most consistent

Step-by-step explanation:

m= 2

x1 = -6

y1 = 3

Applying the formula,

y-y1 = m(x-x1);

we have,

y - 3 = 2(x -(-6))

y- 3 = 2(x + 6)

y - 3 = 2x + 12

y -2x -3 -12 = 0

y -2x -15 = 0

Therefore the equation of the line is;

2x - y + 15 = 0

Answer:

x = -2

Step-by-step explanation:

You can also solve for the equation given.

2x + 7 = 1 - x

3x = -6

x = -2

The solution to the equation 2x + 7 = 1 - x is x = -2.

To solve the equation 2x + 7 = 1 - x by graphing, we can plot the two equations on a graph and identify the point where they intersect.

First, let's graph y = 2x + 7 and y = 1 - x on the same coordinate system.

The equation y = 2x + 7 represents a straight line with a slope of 2 and a y-intercept of 7.

The equation y = 1 - x represents a straight line with a slope of -1 and a y-intercept of 1.

Plotting these lines, we can see that they intersect at a specific point on the graph. The coordinates of this point represent the solution to the equation 2x + 7 = 1 - x.

By visually inspecting the graph, we can determine the point of intersection, which is approximately (-2, 3). This means that x = -2 is the solution to the given equation.

Answer:

The original length of the new candle is 10 inches

Step-by-step explanation:

The form of the linear function is y = m x + b, where

∵ L represents the length of the candle remeaning unburned in inches

∵ t represents the time after the candle was lit in hours

∵ The relationship between L and t is linear

→ Put it in the form of the equation above

∴ L = m t + b, where b is the original length of the new candle

→ Use the table to find m

∵ m = [tex]\frac{L2-L1}{t2-t1}[/tex]

∵ (1, 9) and (6, 4) are two points in the given table

∴ t1 = 1 and L1 = 9

∴ t2 = 6 and L2 = 4

→ Substitute them in the rule of m above

∵ m = [tex]\frac{4-9}{6-1}[/tex] = [tex]\frac{-5}{5}[/tex] = -1

∴ m = -1

→ Substitute it in the equation above

∵ L = -1(t) + b

∴ L = -t + b

→ To find b substitute t by 1 and L by 9

∵ 9 = -(1) + b

∴ 9 = -1 + b

→ Add 1 to both sides

∵ 9 + 1 = -1 + 1 + b

∴ 10 = b

∵ b is the original length of the new candle

∴ The original length of the new candle is 10 inches

Answer:

Aaron's bowling score is 30

David's bowling score is 54

Step-by-step explanation:

The variable representing Aaron's score is = a

The variable representing David's bowling score = d

The sum of their scores is 84.

= a + d = 84...... Equation 1

David's bowling score is 6 less than 2 times Aaron's score.

d = 2a - 6

Substituting 2a - 6 for d in Equation 1

a + 2a - 6 = 84

3a - 6 = 84

3a = 84 + 6

3a = 90

a = 90/3

a = 30

Hence, Aaron's bowling score is 30

d = 2a - 6

d = 2(30) - 6

d = 60 - 6

d = 54

David's bowling score is 54

Answer:

20%

Step-by-step explanation:

The first step is to calculate the increase

= 1.50-1.25

= 0.25

Therefore the percentage increase can be calculated as follows

= 0.25/1.25 × 100

= 0.2 × 100

= 20%

Hence the price increased by 20%

Answer:

if it asking for the type of angle the both are obtuse and the fisrt measure is 135 and the second is 101

Step-by-step explanation:

The relation between 135 and x is corresponding angles.

The value of x is 135 degree.

because the corresponding angles are equal.

Given that the jeweler has alloys that are 25% gold, 50% gold, and 82% gold.

As he wants to make 14 grams of an alloy by adding two different alloys that is precisely 75% gold, so one alloy must have a percentage of gold more than 75%.

One alloy is 82% gold and, the second can be chosen between 25% gold, 50% gold, so there are two cases.

Case 1: 82% gold + 50% gold

Let x grams of 82% gold and y  grams of 50% gold added to make x+y=14 grams of 75% gold, so

75% of 14 = 82% of x + 50% of y

[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 50/100 \times y \\\\[/tex]

[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 50/100 \times (14-x)[/tex]  [as x+y=14]

[tex]\Rightarrow 75 \times 14 = 82 \times x + 50 \times (14-x) \\\\\Rightarrow 75 \times 14 = 82 \times x + 50 \times14-50\times x \\\\\Rightarrow 75 \times 14 = 32 \times x + 50 \times14 \\\\\Rightarrow 32 \times x =75 \times 14 - 50 \times14 \\\\[/tex]

[tex]\Rightarrow x =(25 \times 14)/32=10.9375[/tex] grams

and [tex]y = 14-x= 14-10.9375=3.0625[/tex] grams.

Hence, 10.9375 grams of 82% gold and 3.0625  grams of 50% gold added to make 14 grams of 75% gold.

Case 2: 82% gold + 25% gold

Let x grams of 82% gold and y  grams of 25% gold added to make x+y=14 grams of 75% gold, so

75% of 14 = 82% of x + 25% of y

[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 25/100 \times y \\\\\Rightarrow 75/100 \times 14 = 82/100 \times x + 25/100 \times (14-x) \\\\ \Rightarrow 75 \times 14 = 82 \times x + 25 \times (14-x) \\\\\Rightarrow 75 \times 14 = 82 \times x + 25 \times14-25\times x \\\\\Rightarrow 75 \times 14 = 57 \times x + 25 \times14 \\\\\Rightarrow 57 \times x =75 \times 14 - 25 \times14 \\\\[/tex]

[tex]\Rightarrow x =(50 \times 14)/57=12.28[/tex] grams

and [tex]y = 14-x= 14-12.28=1.72[/tex] grams.

Hence, 12.28 grams of 82% gold and 1.72  grams of 50% gold added to make 14 grams of 75% gold.

It would take 11 months of membership for the total money paid to each club to be the same.

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

Let x represent the number of months subscribed. Hence,

For Roman's gym:

Total payment = 25x + 49.99

For Athens Fitness:

Total payment = 18x + 126.99

For both clubs to have the same payment:

25x + 49.99 = 18x + 126.99

7x = 77

x = 11

It would take 11 months of membership for the total money paid to each club to be the same.

Given that:

Pumping rate is modeled by the equation :

Q(t)=45-t gallons per minute ; where t is in minutes

Number of gallons in tank after 30 minutes ;

Q(t)=45-t

Q(30) = 45 - 30

Q(30) = 15
