a cheetah has the ability to accelerate quickly in 3 seconds suppose a cheetah could travel 1.5 hours at top speed covering 11 1.9 miles. how far can a cheetah travel in 1 hr?
The cheetah will travel a distance of 74.6 miles in one hour.
How do you define the relation of speed, time and distance?Any moving object travels a certain distance over time. We can calculate the speed using these two parameters.
We all know that speed equals distance divided by time. The fundamental unit of speed would be meters per second or 'm'/'s'.However, speed can also be expressed in different units, including such meters per minute as well as kilometers per hour. Speed is usually expressed in kilometers per hour. It is critical to remember that all unit symbols are recorded in the singular.The rate of displacement is actually referred to as speed. These three entities are linked by a formula:
Speed = Distance/Time
The time taken by the cheetah to cover the distance of 111.9 miles is 1.5 hour.
Put the values;
Speed = 111.9/1.5
Speed = 74.6 miles/ hour
Therefore, the distance covered by the Cheetah in 1 hour is 74.6 miles.

Step-by-step explanation:
Does 10x = 2.5x have one solution, no solutions, or infinite solutions, and why?
The values are different on both sides, this shows that the equation has no solution.
Equation and expressionLinear equations are equation that has a linear degree of 1. Given the expression below;
10x = 2.5x
You can see that the variable of "x" are on on both sides, hence we can cancel them out to have:
10x/x = 2.5x/x
10 = 2.5
From the result, you can see that the values are different on both sides, this shows that the equation has no solution.

The linear equation has only one solution, which is x = 0.
How many solutions has the linear equation?
Here we have the linear equation:
10x = 2.5*x
Let's solve this to see how many solutions we have, if we subtract 2.5x in both sides we get:
10x - 2.5x = 0
7.5x = 0
The only solution of this linear equation is x = 0.
7.5*0 = 0
Then we can conclude that the equation has only one solution, which is x = 0.

The average annual wage of workers from a certain country for selected years from 2011 projected through 2021 can be modeled by y= 2286x + 38,620, with y equal to the average annual wage
in dollars and x equal to the number of years after 2010. When does the model project that the average annual wage of workers in the country will be at least $68,400?
Select the correct choice below and fill in the answer box to complete your choice.
(Round to the nearest integer as needed.)
A. in the year
and before
B. in the year
and after
OC. in the year
The average annual wage of workers in the country will be at least $68400 in the year 2023 and after , the correct option is option (B) .
In the question it is given that
model of the average annual wage (y) = 2286x + 38620 ...(i)
where x = number of years after 2010,
It is also given that the average annual wage(y) must be at least 68,400 .
which means y ≥ 68400
Substituting value of y from equation (i) we get ,
2286x + 38620 ≥ 68400
Simplifying the inequality further we get ,
2286x ≥ 68400 - 38620
2286x ≥ 29780
x ≥ 29780/2286
x ≥ 13.02 ≅ 13
Hence , the average annual wage will more than the specified value from the year, 2010+13 = 2023 .
Therefore , the average annual wage of workers in the country will be at least $68400 in the year 2023 and after , the correct option is option (B) .

A garden table and a bench cost $783 combined. The garden table costs $83 more than the bench. What is the cost of the bench?
Answer:
$350
Step-by-step explanation:
Let the cost of the bench be x. Then, the cost of the table is x+83.
[tex]x+x+83=783 \\ \\ 2x+83=783 \\ \\ 2x=700 \\ \ x=350[/tex]
The total cost is,
→ $783
Let the cost of garden table be,
→ x + $83
Then the cost of bench will be,
→ (x + 83) + x = 783
→ 2x + 83 = 783
→ 2x = 783 - 83
→ x = 700/2
→ [ x = $350 ]
Hence, the cost of bench is $350.

Find the missing coordinate (x,5) and (3,3) m= 1/2
The missing coordinate of the points is 7
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the missing coordinate?The given parameters are
Slope, m = 1/2
Points (x1, y1) = (x, 5) and (x2, y2) = (3, 3)
The slope of a linear equation is calculated as
m = (y2 - y1)/(x2 - x1)
So, we have
1/2 = (3- 5)/(3 - x)
Evaluate the differences
So, we have
1/2 = -2/(3 - x)
Cross multiply
So, we have
3 - x = -4
This gives
x = 3 + 4
Evaluate the sum
x = 7
Hence, the missing coordinate of the points is 7

of an amortization table for the first period of the loan.

Using proportions, the financial measures for the home purchase are given as follows:
Beginning Balance: $220,000.Interest owed: $228,076.4.Payment toward principal: $33,000.Ending balance: $448,076.4.What is a proportion and what is an example of application?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using the unit rates, which along with operations such as multiplication or division are used to find the equivalent measures.
For this problem, the beginning balance is the purchase value of the home, hence:
Beginning Balance: $220,000.
15% of that goes towards the down payment, hence:
0.15 x 220,000 = $33,000.
Payment toward principal: $33,000.
The number of monthly payments is given by:
20 x 12 = 360 monthly payments.
Considering the monthly payment, the ending balance is given as follows:
33,000 + 360 x 1,152.99 = $448,076.4.
