Answer: The first and fourth pair of polygons are similar.

Step-by-step explanation:

If two polygons are similar then their corresponding sides are proportional.

Let's check

In the first pair there are two rectangles and their dimensions are proportional as

$\frac{22}{13.75}=\frac{16}{10}=1.6$

In the second pair there are right triangles but their dimensions are not proportional as

$\frac{18}{8}=2.25$ and $\frac{30}{17}=1.76$

In the third pair there is one isosceles triangle and other is equilateral triangle, which can not be similar as they have different type of triangles.

In the fourth pair there are two right trapezoid and their dimensions are proportional as

$\frac{7.5}{3}=\frac{30}{12}=\frac{12.5}{5}=\frac{20}{8}=2.5$

What ere the coordinates of the point on the directed line segment from (-1,7) to (7,7) that partitions the segment into a ratio

djverab [1.8K]

Answer:

$(\frac{37}{11},\frac{77}{11} )$

Step-by-step explanation:

Given two points are (-1,7) and (7,7).

We are told to find a point which is in between them at a ratio of 6:5.

Formula for calculating a point at distance of ratio m:n is given by

$(\frac{mx2+nx1}{m+n} ,\frac{my2+ny1}{m+n} )$

where $(x1,y1),(x2,y2)$ are the inital and final points.

$(x1,y1)=(-1,7)\\\\(x2,y2)=(7,7)$

also m:n=6:5 ,

by substituting all the values we get,

$(\frac{6*7+5*-1}{11} ,\frac{6*7+5*7}{11} )$

$(\frac{37}{11},\frac{77}{11} )$

Determine the area that is bounded by the graphs of the following equations on the interval below. (Round your answer to three d

Elza [17]

Answer:

A≅407.34 au (area units)

Step-by-step explanation:

we must find the area generated by equations a., b., and c. To do this we must graph and the areas and determine their points to evaluate

As seen in the graphs (1, 2) we have the area generated by equations a. b. and the limits within which the area should be evaluated are those determined by c.

Finally we find A (view graph 3)

This chart shows Dan’s budget:

Drupady [299]

The correct answer is D No, Dan should reduce his discretionary spending

Explanation:

For Dan to stay on the budget he needs to spend the amount budgeted for each expense or less than the amount budgeted. This occurred in the case of the Internet, food, and rent; for example, the amount budgeted for the internet was $35 and Dan spent this money, also, the amount budgeted for food was $100 and Dan spent $95, which means he stood in the budget. However, this did not occur with discretionary spending, which refers to other non-necessary expenses, because in this case, Dan spent $140 even when the budget limit was $100. Also, this exceeds the total income considering 35 + 95 + 500+ 140 = $770, which is above the income ($750). Thus, Dan did not stay in the budget because he spent more money than expected in discretionary spending and should reduce this.
