Jillian has $50 that she plans on investing in an account that will double her money every week. This can be represented by the
Arte-miy333 [17]
The part that would change would be the number 2.  It would become a 3 instead of the 2.  Tripling something means to have 3 groups of it.

The reason is that the $50 is not changing, nor would the number of weeks, x be changing.

1. The diagonal of a quadrilateral
zalisa [80]

Consider the length of diagonal is 8.5 cm instead of 8.5 m because length of perpendiculars are in cm.

Given:

Length of the diagonal of a quadrilateral = 8.5 cm

Lengths  of the perpendiculars dropped on  it from the remaining opposite  vertices are 3.5 cm and 4.5 cm.

To find:

The area of the quadrilateral.

Solution:

Diagonal divides the quadrilateral in 2 triangles. If diagonal is the base of both triangles then the lengths  of the perpendiculars dropped on  it from the remaining opposite  vertices are heights of those triangles.

According to the question,

Triangle 1 :  Base = 8.5 cm and Height = 3.5 cm

Triangle 2 :  Base = 8.5 cm and Height = 4.5 cm

Area of a triangle is

Area=\dfrac{1}{2}\times base \times height

Using this formula, we get

Area(\Delta 1)=\dfrac{1}{2}\times 8.5\times 3.5

Area(\Delta 1)=14.875

and

Area(\Delta 2)=\dfrac{1}{2}\times 8.5\times 4.5

Area(\Delta 2)=19.125

Now, area of the quadrilateral is

Area=Area(\Delta 1)+Area(\Delta 2)

Area=14.875+19.125

Area=34

Therefore, the area of the quadrilateral is 34 cm².

What is the average (with 0 decimal places) across all schools for the total score? Group of answer choices 1287 1215 1221 1229
Irina18 [472]

Answer:

See explanation

Step-by-step explanation:

Required

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

\bar x = \frac{\sum x}{n}

Assume the data is:

1287\ 1215\ 1221\ 1229

This means that the number of schools is 4

So:

\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}

\bar x = \frac{4952}{4}

\bar x = 1238

<em>The average of the assumed data is 1238</em>
