Answer:

Johnny will be able to reach the safe zone before the gate is closed.

Step-by-step explanation:

Given that:

Distance of Little Johnny from safe zone = 4000 feet

Time = 3 minutes

Speed = 22 mph

To find:

Will Johnny be able to reach the safe zone ?

Solution:

Johnny can only be safe if he can travel 4000 feet in 3 minutes with the given speed.

Let us try to find out, the distance that he can travel in 3 minutes at speed of 22 mph.

Let us have a look at the formula of distance traveled:

[tex]Distance = Speed \times Time[/tex]

Time = 3 minutes = [tex]\frac{3}{60}[/tex] hrs

Speed = 22 mph

[tex]Distance = 22 \times \frac{3}{60}\\\Rightarrow Distance = \dfrac{22}{20}\ miles \\\Rightarrow Distance = 1.1\ miles[/tex]

We know that 1 mile = 5280 feet

Therefore 1.1 miles = 5280 [tex]\times[/tex] 1.1 feet = 5808 feet

Distance traveled by Little Johnny is greater than 4000 feet.

Therefore Johnny will be able to reach the safe zone before the gate is closed.

Answer:

n = -3

Step-by-step explanation:

Original Equation:

11 (n-1) + 35 = 3n

Distributive Property:

11n + 24 = 3n

Subtract 24 from both sides:

11n + 24 - 24 = 3n - 24

Simplify:

11n = 3n - 24

Subtract 3n from both sides:

11n - 3n = 3n - 24 - 3n

Simplify:

8n = -24

Divide both sides by 8:

[tex] \frac{8n}{8} = \frac{ - 24}{8} [/tex]

Simplify:

n = -3

Answer:

n=-3

Step-by-step explanation:

Answer:

x≥ -3

Step-by-step explanation:

The domain is the values that x can take

Answer:

it should be 80

Step-by-step explanation:

100 squared is 10

400 squared is 20

80 does not have an exact answer 8.944 so it is 80

Answer:

0.55x+4<=25

Step-by-step explanation:

It would be 0.55x because x is the number of bananas and 0.55 is the cost and the 4 represents the $4 she spent for a papaya. The 25 is the amount of money she has so it says less than or equal to because she only has so much money.

Answer:

3x^3 + 12x^2 - 45x

Step-by-step explanation:

Multiply 3x with x^2 then 4x and then -15 in order

3x × x^2 = 3x^3

3x × 4x = 12x^2

3x × (-15) = -45x now add the expressions

3x^3 + 12x^2 - 45x

Any number that can be written in p/q from is a rational number

Answer:

8- b=79

9- b=23

10- b=67

8.)

[tex]37 = n - 42[/tex]

Add 42 to both sides of the equal sign to isolate the variable (n).

[tex]79 = n[/tex]

9.)

[tex]b + 62 = 85[/tex]

Subtract 62 from both sides of the equal sign to isolate the variable (b).

[tex]b = 23[/tex]

10.)

[tex]92 = 25 + l[/tex]

Subtract 25 from both sides of the equal sign to isolate the variable (l).

[tex]67 = l[/tex]

Answer:

$271.00. Remember to put it in the right format

Step-by-step explanation:

So since its 35 dollars per day, we can first do 35*4 to get 140. So just for having the car, it costs 125 dollars.

Now to find the amount of money for the miles, we can do 730*0.20=146

Now we add those two amounts so we do 125+146=271.

So $271.00

Relationship of angle pairs considering the given diagram are as follows:

1. <d and <e are alternate interior angles. They are opposite inner sides of the transversal.

2. <e and <h are vertically opposite angles. They share the same vertex (corner) formed by the two line that crossed.

3. <a and <e are corresponding angles. They occupy the same position as a line crosses the other two lines together.

4. <c and <d are a linear pair. They are angles on a straight line and are supplementary.

The relationships between the angle pairs are:

1. Angle d and angle e are alternate interior angles.

2. Angle e and angle h are vertically opposite angles.

3. Angle a and angle e are corresponding angles.

4. Angle c and angle d form a linear pair.

The relationships between the angle pairs in the given diagram can be described as follows:

1. Angle d and angle e are alternate interior angles.

They are located on opposite sides of the transversal and inside the pair of lines.

2. Angle e and angle h are vertically opposite angles.

They are formed at the same vertex (corner) where the two intersecting lines meet.

3. Angle a and angle e are corresponding angles.

They are positioned in the same relative location as a line intersects the other two lines simultaneously.

4. Angle c and angle d form a linear pair.

They are adjacent angles on a straight line and add up to 180 degrees, making them supplementary.

Answer: First we will substitute the numbers in place of the variables in the equation, and then we will use order of operations to solve.

7x + 6y would be equal to:

7(2) + 6(10)

Now we will perform the multiplication:

7 * 2 = 14

6 * 10 = 60

The equation now looks like:

14 + 60

This is equal to 74. Your answer is therefore 74.

Hi there! Hopefully this helps!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we need to evaluate the variables into the expression.

7x + 6y = 7(2) + 6(10).

6 x 10 = 60

7 x 2 = 14.

60 + 14 = 74

Step-by-step explanation:

F1 = 1

F2 = 1 + 2

F3 = 1 + 2 + 3

--> The n(th) figure has the number of oranges = the sum of the first n natural numbers, which has the general form:

F(n) = 1 + 2 + 3 + ... + n = n(n+1) / 2
