Answer:

40 km on the highway

30 km on the city roads

Step-by-step explanation:

Let x = highway

Let y = city road

The time formula: time = distance / speed.

1) Since we do not know the distance travelled on the highway and city roads but we do know the total time taken, we can say x + y = 70. Set the distances x and y and all equated to 2 hours, since we do not know them, nor do we know the time. This is called a system of equations.

x + y = 70

x/80 + y/20 = 2

2) Solve the system of equations using substitution.

x = 70 - y

---------------

70 - y/80 + y/20 = 2

70 + 3y/80 = 2

y = 30

---------------------------------

x + 30 = 70

x = 70 - 30

x = 40

Therefore, the delivery truck travelled 40 km on the highway and 30 km on the city roads.

Answer:

The 17th term of the given Arithmetic progression -6,-1,-4 will be 74.

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

The arithmetic progression has wider use in mathematics for example sum of natural numbers.

Natural number = 1,2,3,4,5,6,7,8...

As per the given Arithmetic progression,

-6, -1, -4.

First term a = -6

Common difference d = -1 - (-6) = 5

The nth term of AP is given as a + (n - 1)d.

This 17th term will be as, -6 + (17 - 1)5

⇒ -6 + 16 × 5 = 74

Hence "The 17th term of the given Arithmetic progression -6,-1,-4 will be 74".

The exponent is greater than 1 so it is exponential growth, 500 in the equation represents the initial value, and the growth rate in the second equation is 6%.

During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.

We have an exponential function:

[tex]\rm b_1(t) = 500(1.6)^t[/tex]

a) As the base of the exponent is greater than 1 so it is exponential growth.

b) 500 in the equation represents the initial value.

c) We have another exponential equation:

[tex]\rm b_2(t) = 800(1.6)^t[/tex]

For exponentikal gropwth:

1 + r = 1.6

r = 0.6 or

r = 6%

In the equation:

[tex]\rm b_1(t) = 500(1.6)^t[/tex]

The number of bacteria initially was 500 and from the second the number of bacteria initially was 800.

Thus, the exponent is greater than 1 so it is exponential growth, 500 in the equation represents the initial value, and the growth rate in the second equation is 6%.

Flo should walk 60 extra minutes of time per day to accomplish her goal of walking 12,000 total steps per day.

Calculating the Time for Which Flo Walks Each Day

Flo walks 6,000 steps per day.

She walks 100 steps per minute.

⇒ Time taken by Flo to cover 6,000 steps = [tex]\frac{6000}{100}[/tex] minutes

⇒ Time taken by Flo to cover 6,000 steps, m₁ = 60 minutes

Hence, Flo walks for 60 minutes or 1 hour per day.

Calculating the Extra Hours of Walking

Steps to be covered by Flo each day = 12,000

Time required to walk 12,000 steps per day, m₂ = [tex]\frac{12000}{100}[/tex] minutes

⇒ m₂ = 120 minutes

Extra hours of walk per day = (m₂-m₁) minutes

= (120 - 60) minutes

= 60 minutes

Thus, Flow should walk 1 hour extra to be able to accomplish a goal of walking 12,00 steps per day.

Answer: [tex]60cm^2[/tex]

Step-by-step explanation:

Looking at the figure, you can see that the length is 5cm + 3cm = 8cm and the width is 2cm + 5cm + 2cm = 9cm.

The formula for area is length x width, therefore you do 8x9 which is 72.

Next, we solve for the two "dips" in the rectangle. We can do that by subtracting the area of the "mini-rectangles" from the whole figure:

72-2(2x3) = 60

Thus, 60cm^2 is your answer.
