5. Which integer best represents a deposit of $37? *
A. 37
B. −37
C. −⎪37⎥
D. −⎪−37⎥

Answers

Answer:

A. 37.

Step-by-step explanation:

In B, that is making a withdrawal.

In C, because of the *||*s around it, this means that the number inside of those lines will always be positive. But the negative is outside of the lines so it is still negative.

In D, you might think that the |-37| cancels out the - on the outside. But like I said, those lines mean that anything inside of the lines will always be positive. Meaning that the |-37| inside just becomes |37| and still turns negative because of the - on the outside.

This means that angles AED and CED are right angles.
We also see that ED = ED by the
property. Therefore, we have that AAED = ACED by

Answers

The solution to the missing gaps of the kite are as follows; kite; perpendicular, reflexive, SAS

What is the proof of the quadrilateral?

1) AD ≅ CD. This is as a result of the definition of a kite.

2) From the kite diagonal theorem, The diagonals meet at right angles and as such AC is perpendicular to BD.

3) ED ≅ ED by reflexive property of congruence.

4) ΔAED = ΔCED by SAS congruency theorem.

Brooke went to the hardware store and bought 20 identical copper pipes. When Brooke lined up the pipes end-to-end, the line was 1 meter long. How long was each pipe?

Answers

Answer: 5cm

Step-by-step explanation:

First and foremost, we should note that

1 meter = 100 centimeters

Therefore, since Brooke went to the hardware store and bought 20 identical copper pipes and their total length is 1 meter long which is 100cm, the length of each pipe will be the title length of the Pipe divided by the number of pipes. This will be:

= 100 / 20

= 5cm each.

Each pipe is 5cm long.

Answers

Answer:

a) 13.4

Step-by-step explanation:

This will use the pythagorem theorm. Which is a^2 + b^2 = c^2. You'll start with 12^2 + 6^2 = c^2. Then you'll solve from there.

12^2 + 6^2 = c^2

144 + 6^2 = c^2

144 + 36 = c^2

180 = c^2

then you'll find the square root of 180 (i don't have that symbol on my keyboard)

/180 = c

6/5 = c

then in decimal form it's 13.4164...

so rounded it's 13.4

If the simple interest on $7000 for 3 years is $1890, then what is the interest rate?

Answers

Answer:

Step-by-step explanation:

I = Prt

Given:

I = 1890

P = 7000

t = 3

Work:

I = Prt

r = I/(Pt)

r = 1890/(7000 x 3)

r = 1890/21000

Find the errors in her solution. What should her answer have been?

Lin's Steps - 8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (13)
8x - 24 + 7 = 26x
8x - 17 = 26x

Answer:

(a) Yes, AA postulate (b) SSS theorem long side: 35; total perimeter: 80

Step-by-step explanation:

1. Both triangles are right triangles, and the vertical angles at C are the same measure. Hence, the triangles are similar because they have two congruent angles: the AA postulate applies.

2. The shortest-to-longest side ratios are ...

3 : 6 : 7

18 : 36 : 42 = 6(3) : 6(6) : 6(7) = 3 : 6 : 7

Corresponding sides are proportional, so the SSS theorem applies.

3. Larger triangle side lengths are a factor of 5 times those of the smaller triangle. The missing side of the larger triangle is 5×7 = 35. The total perimeter of the larger triangle is 20+25+35 = 80. The required length of fence depends on what is being fenced (not specified).

What is the Constant of a Linear Graph?

The constant of a linear graph, is the slope of the line = change in y / change in x.

Using any of the two points on the line, (2, 5) and (4, 10):

Constant/slope = (10 - 5)/(4 - 2)

Constant/slope = (5)/(2)

Constant/slope = 2.5
