not sure what class this is for but I\ll try. Each traveller has a 21 km drive so their fare should be equal.

method 1) each traveller can pay for 21 km worth when they get out

method 2) Curly can pay the full fare and Andy and Bob can pay him back later (they're brothers so this should be easy to manage)

Answer:

2

Step-by-step explanation:

Since they are similar triangles then the ratio will be the same on all sides.

You know the one side 5 is the same ratio to 5x   so you multiply x to all sides of the little triangle to get the value of the equivalent side in the big one.

so the missing side x times x will equal the big size of the bigger triangle which is 4

x times x = 4   can only be 2

Answer:

Answer:

Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

Step-by-step explanation:

Here, we want to choose the correct option

As we are having a circular projection, we should be looking at having a parabolic representation i.e a model that looks like a parabola

So the correct answer in this case is that;

Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

Answer:

Step-by-step explanation:

Answer:

3 , 11, 25, 45

Diff 8 14 20

Diff 6 6

The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3

therefore 3n^2

3 11 25 45

3n^2 3 12 27 48

Remainder 0 -1 -2 -3

Difference -1 -1 -1

linear sequence with nth term -n+1

so nth term of quadratic sequence in 3n^2-n+1

Answer:

$40 per week

Step-by-step explanation:

Step one:

Given data

the initial amount is = $100

the total amount= $500

let the number of weeks be x

Step two:

The expression for the scenario is

[tex]500= 100+40x-------1[/tex]

From the expression above, the rate of the change is $40 per week.

this means that in every week the account will be increased by $40

Answer:

x=6 is not a solution

Step-by-step explanation:

We can substitute 6 as x to find out:

5(6-3)=6+13

first, because of PEMDAS we'll do 6-3

5(3)=6+13

multiply 5 by 3 and add 6 and 13

15=19

Since the statement is not true, that means that x=6 is not a solution

Answer:

It's the dot that's right in the middle of the rest, where the two lines meet.

Step-by-step explanation:

That's the equilibrium point.

The equilibrium point of the given graph is at (35, 90)

The demand curve shows the quantities of a particular good or service that buyers will be willing and able to purchase at each price during a specified period. The supply curve shows the quantities that sellers will offer for sale at each price during that same period.

Given that, the supply and demand curves for a new style of silver earrings are shown.

We need to find the equilibrium point,

We know that, On a demand and supply graph, the equilibrium point can be found where the demand and supply curves intersect. Price is on the axis on both the demand and supply curves, and quantity demanded is on the axis.

In our graph, the curves are intersecting at (35, 90)

Hence, the equilibrium point of the given graph is at (35, 90)

4. no

5. yes

Step-by-step explanation:

The questions you're asking relate to the Triangle Inequality Theorem, which states that the two smallest sides (ex. 6 and 13) have to be of greater value than the largest side (ex. 18)

1. 6+13>18

2. 34+27>58

3. 29+9=38 (since the value of the two smallest sides are equal, it does not apply to the Triangle Inequality Theorem, and therefore won't be a triangle)

4. 12+12<25

5. 19+14>31

Answer:

Q'(15, -3)

Step-by-step explanation:

Multiply the coordinates by the scale factor to get the new coordinates.

5 · 3 = 15

-1 · 3 = -3

Therefore, Q'(15, -3).

The maximum  number of miles Rachel can run on the third day without going over the planned average of  6.4 miles per day is 6.1 miles.

Let x represent the maximum  number of miles

Formulate

6.6+6.5+x÷3=6.4

Hence:

6.6+6.5=6.4×3

13.1+x=19.2

x=19.2-13.1

x=6.1 miles

Inconclusion the maximum  number of miles Rachel can run on the third day without going over the planned average of  6.4 miles per day is 6.1 miles.
