The vertices of a quadrilateral ABCD are A(4, 8), B(10, 10), C(10, 4), and D(4, 4). The vertices of another quadrilateral EFCD are E(4, 0), F(10, -2), C(10, 4), and D(4, 4). Which conclusion is true about the quadrilaterals? (5 points)A.The measure of their corresponding angles is equal.
B.The ratio of their corresponding angles is 1:2.
C.The ratio of their corresponding sides is 1:2
D.The size of the quadrilaterals is different but shape is same.

Answers

Answer 1

Answer: The right answer for the question that is being asked and shown above is that: "D.The size of the quadrilaterals is different but shape is same." The two quadrilaterals are similar. Quadrilateral EFCD is just a mere reflection of quadrilateral ABCD.

A total of $8000 is invested: part at 7% and the remainder at11%. How much is invested at each rate if the annual interest is $760?

Answers

1.) .07x + .11y = 760
2.) x + y=8000

we can solve the second equation for either x or y

y= 8000 - x
or
x=8000 - y

plug 1 of those in to equation 1 (I'll use y=8000 -x)

.07x + .11(8000 -x) = 760

.07x + 880 - .11x = 760

-.04x +880 = 760

-.04x = -120

x=3000

So 3000 is invested in 7%
5000 is invested in 11%

Check

(3000 x .07) + (5000 x .11) = 720

210 + 550 = 760

1) In 2001, there were about 62.5 thousand golden retrievers registered in the United States. In 2002, the number was 56.1 thousand. Which linear equation best represents this information?(A) y = 6.4x + 2001
(B) y = -6.4x + 12868.9
(C) y = 6.4x - 12743.9
(D) y = -6.4x + 2002

Answers

Linear equation is y=ax+b
Its decreasing so u need - a
2001 and 2002 would be your x at liner equation so can't have them as b
so answer is B

The Answer Is B y=-6.4*+12868.9

What are scale drawings? can you give an example?

Answers

Scale Drawings are drawings that are used to show the true size of something.
Scale drawings are most commonly used in maps, or in large scale drawings. These show the scale of something. It may show that 1cm is equivalent to 1km, which would allow someone to measure the map to see how far the distance it. It also allows a map to be made smaller, and less detailed- making it often easier to read.
Hope this helps :)
