The sides of a rectangle are in the sides of a rectangle are in the ratio 7:3. The perimeter of the rectangle is 40cm. Find the area of the rectangle

Answer:

Step-by-step explanation:

2m in height : 11m in length

300m in length: 1650m in length

This is because you multiply each side by 150.

The horizontal length will be 1650m.

If the price of an item is $20.00 with a sales tax of 4%, the total cost of the item is $20.80.

The total cost involves adding the price and the sales tax amount.

We can compute the total cost by determining the sales tax factor using the sales tax rate as follows:

The price of the item = $20.00

Sales tax = 4% = 0.04 (4/100)

The sales tax factor = 1.04 (1 + 0.04)

Thus, the total cost, including the price and the sales tax, is $20.80 ($20 x 1.04).

The revenue of US theme parks in 2012 is 14.5 in dollars.

Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.

From the given table, (1990, 5.7), (1992, 6.5), (1994, 7.0), (1996, 7.9), (1998, 8.7), (2000, 9.6), (2002, 9.9), (2004, 10.8), (2006, 11.5).

Using the coordinates (1990, 5.7) and (1992, 6.5), we get

Slope m=(6.5-5.7)/(1992-1990)

= 0.8/2

= 0.4

Substitute m=0.4 and (x, y)=(1990, 5.7) in y=mx+c, we get

5.7=0.4×1990+c

c=5.7-796

c=790.3

Substitute m=0.4 and c=-790.3 in y=mx+c, we get

y=0.4x-790.3

Substitute x=2012, we get

y=0.4×2012-790.3

y=804.8-790.3

y=14.5

Therefore, the revenue of US theme parks in 2012 is 14.5 in dollars.

Answer:

Option A

Step-by-step explanation:

Here is how to approach the problem:

We see that all our restrictions for all four answer choices are relatively the same with a couple of changes here and there.
One way to eliminate choices would be to look at which restrictions don't match the graph.

At x<-5, there is a linear function that does have a -2 slope and will intersect the x axis at -7. The line ends with an open circle, so any answer choice with a linear restriction of x less than or equal to -5 is wrong. This cancels out choices C and D.

Now we have two choices left.

For the quadratic in the middle, the vertex is at (-2,6) and the vertex is a maximum, meaning our graph needs to have a negative sign in front of the highest degree term. In our case, none of our quadratics left are in standard form, and instead are in vertex form.

Vertext form is f(x) = a(x-h)^2 + k.

h being the x-coordinate of the vertex and k being the y-coordinate.

We know that the opposite of h will be the actual x-coordinate of the vertex, so if our vertex is -2, we will see x+2 inside the parenthesis. This leaves option A as the only correct choice.

Answer: 3

You're going to multiply 3 by 2 which gives you 6. you then have 6 over 2. Next find a number that goes into both of them which is 2 in this case. So now you divide the top and bottom by 2, so now you have 3 because two divided by two is zero, that is as small as it gets.

The expression that can be used to represent the total money earned is $12x - $15.

The first step is to determine the total amount earned this wek. This can be determined by multiplying the earnings per hour by the total hours/

Total earnings = $12 ×x = $12x

Now subtract the late delivry charge = $12x - $15
