Answer:
Step-by-step explanation:
Given : Michael pays $30 to enter a state fair, plus $4 for each ride.
To Find: Which of the following equations represents his total cost?
Solution:
Let x be the number of rides .
Cost of 1 ride = $4
So, cost of x rides = 4x
We are given that Michael pays $30 to enter a state fair
Entry fee = $30
Let the total cost be y
So, total cost =
Hence the equation represents his total cost is .

The number of orders in is equal to the number of orders out in month 4 (April). It appears the solution represents the time at which warehouse shipments caught up with order quantities.
_____
For this table to make any sense, we have to assume that the year started with 3 orders in January, and that one order was shipped in January. Then the number of orders was 1 or 2 each month after that, and the number of orders shipped per month was 2 each month after that. That is, the tables represent year-to-date totals of orders in and out.
<em>Alternate Interpretation</em>
If the numbers here are actual orders in and out in each of the listed months, it appears the warehouse is getting better at shipping orders. That is, they are increasing the shipment rate by 2 orders a month each month. They will eventually ship enough to cover the total number of orders in (total of 20 by April), but total shipments through April only amount to 16 orders.
To solve this we can take two different approaches:
1. We can substitute theta by 30° and evaluate our expression using a calculator:
2. We can use the unitary circle and the fact that
, so we can rewrite our expression as follows:
From our unitary circle we can check that
and 
.
Lets replace those values in our expression and simplify:
Either way we can conclude that the correct answer is: D)8.7

Answer with explanation:
Length of an object
cm
Other unit of measurement are Meter and Kilometer.
→1 Meter = 100 cm
→1 Kilometer= 1,000 meter=100,000 cm
→→21,000 cm = 210 meter = 0.21 Km
Option B:→ length of a city park, is most suitable measurement ,among all other measurement ,that Brad has done.
Second option Might be: Option A→ Length of a city block , may be That Brad has measured.
All other options are Inappropriate, as they require smaller scale or may be larger Scale ,that brad has used to measure
1.≡ Height of a person →→→240 cm (Maximum of 8 feet)
2. ≡Distance across a city →→→1 Km or 2 Km or 3 Km...
3. ≡Height of an apple tree→→→1,000 cm (Maximum)
4. ≡Width of a screen in a theater→→→2,100 cm (Maximum)
5 ≡depth of water in a swimming pool→→→225 cm
None of the five things described above appears, that brad has measured.
