Answer:

x = ≈4.78

Step-by-step explanation:

25.1226x / 7.85 = 15.3

25.1226x = 15.3 × 7.85

25.1226x = 120.105

divise by 25.1226 to isolate x

x = ≈ 4.78

Trying to solve a exponential function question. Evaluate the function when t=5.
Gemiola [76]
If t=5 then all you do is plug that into the function:
h(t)=175(1028)5
You would start by multiplying 1028 by 5 which leaves you with 5140, now plug that into the function.
h(t)=175(5140)
multiply 175 and 5140
h(t)=899500

Grace uses a different way to divide 2.16 by 0.25 .She divides both the divisor and dividend by 0.01 to make an equivalent probl
liraira [26]

Answer:

8.64. Her work is correct

Step-by-step explanation:

Given the expression to divide 2.16 by 0.25

Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;

2.16/0.25 = (2.16/0.01)÷(0.25/0.01)

(2.16/0.01)÷(0.25/0.01) = 216/25

216/25 = 8.64

Hence her value is 8.64 making her work correct

A fair owner made 18 dollars when a group of three entered which is the rate of fair per person
Masteriza [31]

Let's start with an example.


At the market, 8 batteries cost $10.

How much do 6 batteries cost?

We’re trying to find the cost of 6 batteries.

Batteries                        Cost

8 / 8 = 1                         $10/ 8 = $1.25

If 8 batteries cost $10, then 11 battery costs $1.25.

Batteries                        Cost

8                                     $10

1 x 6                               $1.25  x 6        

6                                    $7.50        

So, 6 batteries cost $7.50.


Back to your question...

We are trying to find the rate of fair which means the fair price for 1 person


Fair                                 Person

18/3                                  3/3

6                                        1


So, the fair owner will make $6 for 1 person.

Hope this helped! Good luck!

A go-cart racetrack has 100-meter straightaways and semicircular ends with diameters of 40 meters. Calculate the average speed i
emmainna [20.7K]

Answer:

Average speed of go cart is 217.07 meters per minute.

Step-by-step explanation:

We are given the following in the question:

Length of straightway racetrack = 100 m

Diameter of  semicircular end = 40 m

Radius =

r = \dfrac{d}{2} = \dfrac{40}{2} = 20\text{ m}

Perimeter of racetrack =

Perimeter of semicircle + 2(Length of straightway) + Perimeter of semicircle

=\pi r + 2(100) + \pi r\\=2\pi r + 2(200)\\=(2\times 3.14\times 20) + 200\\=325.6\text{ m}

Speed =

s = \dfrac{\text{Distance}}{\text{Time}}\\\\s = \dfrac{4\times \text{Perimeter of track}}{6}\\\\s = \dfrac{4\times 325.6}{6}\\\\s = 217.06\text{ meter per minute}

Thus, average speed of go cart is 217.07 meters per minute.
