Find the simple interest on $900 for 18 months at a rate of 9.5% per year

1 answer:

6 0

To get the simple interest, we must use the formula: I= (p)(r )( t)
So, in this one we need to multiply $900x18x9.% and the answer will be $128.25. This is the amount of interest they are going to pay per year.

Domain and Range...

Veseljchak [2.6K]

The domain is the X values and the range is the y values.

The blue line starts at X 0 and Y 0 and moves up and to the right.

This means the range and domain are equal to or greater than 0.

The 3rd choice is the correct one.

on the last 5 quizzes, marco has earned a total of 21 out of 25 possible points. if he has a perfect score on the next several q

nevsk [136]

Using the mean concept, it is found that we will need 15 more points to bring up his average up to 90%.

The mean of a data-set is the <u>sum of all observations divided by the number of observations</u>.

In this problem:

In the first 5 observations, total of 21 out of 25 points, hence the mean for these observations is $\frac{21}{25} = 0.84$ .
In the next n observations, mean of 1.

Hence, the mean is:

$M = \frac{0.84(5) + n}{5 + n} = \frac{4.2 + n}{5 + n}$

We want the mean to be of 0.9, thus:

$M = 0.9$

$\frac{4.2 + n}{5 + n} = 0.9$

$4.2 + n = 0.9n + 4.5$

$0.1n = 0.3$

$n = \frac{0.3}{0.1}$

$n = 3$

3 more testes are need, each worth 5 points, hence, 15 more points are needed to bring up his average up to 90%.

What is the area of a rectangle with side lengths of 5 12 foot and 2 3 foot

vazorg [7]

Answer:

3 2/3ft²

Step-by-step explanation:

Area of a rectangle = Length × Width

Given

Length = 5 1/2 foot

Width = 2/3foot

Substitute

Area of the rectangle = 5 1/2 × 2/3

Area of the rectangle = 11/2×2/3

Area of the rectangle = 22/6

Area of the rectangle = 11/3

Area of the rectangle = 3 2/3ft²

How can you find the area of a triangle using the Law of Sines?

aniked [119]

Explanation:

One formula for the area of a triangle is ...

Area = (1/2)ab·sin(C)

This presumes you know the measures of two sides and the angle between them. The Law of Sines is typically used where you know all the angles and only one side measure.

You would use the law of sines to find an additional side measure, then make use of the above formula for area.

Which inequality represents all values of X for which the product below is defined

balandron [24]

The domain for which the function is defined is given by:

D. $x \geq 4$ .

<h3>What is the domain of a function?</h3>

The domain of a function is the set that contains all possible input values for the function.

A square root is only defined for non-negative values, hence:

$x - 4 \geq 0 \rightarrow x \geq 4$ .

$x + 1 \geq 0 \rightarrow x \geq -1$ .

The intersection of these two domains is $x \geq 4$ , hence option D is correct.
