What is 15% of 450 show your work

Answers

Answer 1

Answer: Easy, change 15% into 0.15

n=0.15*450

n=67.5

Thus, your answer is, 67.5

Answer 2

Answer: 15 becomes 0.15 after you divide 15 by 100
Next, do 0.15 times 450 which equals
67.5
rounded, this would become 68
So, the answer is 67.5

Take the current year and subtract is from the initial year, so
This year is 2016, your are trying to find age if born in 1983
   2016
   - 1983
   -------------
        33
You would be 33 years old if you were born in 1983 as of 2016.

Either 32 or 33 years old depending on the exact date.

What is the measure of ∠CAB?Help! This is worth 25 pts!!

Answers

B.56
the sum of the degree of angles in a triangle is always 180 degrees. since angle ABC is 90 degrees and angle ACB is 34 degrees, the last angle, which is angle CAB, is 180 - 90 - 34 = 56

Using coordinate geometry, prove that Quadrilateral MIKE is a Parallelogram:

Answers

Answer: It has two pairs of parallel lines

Step-by-step explanation:

coordinates of E (-4,4) K (4,4) M(-6,-3) I( 2,-3)

The distance from E to K is 8 the same as the distance from M to I.

The distance from M to E is about 7.3 and the distance between K and I is the the same thing.

Answer:

Counting the unit on graph, we observes:

EK = MI = 8

EK // MI // x-axis

=> MEKI is parallelogram

What is the equation of a line that passes through the point (8,1) and is perpendicular to the line whose equation is y= -2/3 x + 5? A) 2X+3Y= 15
B) Y= -2/3x + 11
C) Y= 3/2x+ 11
D) y= 3/2x - 11

I am thinking its B but am not sure. I don't wanna retake this so I wanna be 100%. Thanks!!

Answers

Answer:

The equation of this line would be y = 3/2x - 11, which is the answer D.

Step-by-step explanation:

In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is -2/3, which means the new slope will also be 3/2 because perpendicular lines have opposite and reciprocal slopes. Now, we can use this slope along with the point in point-slope form to find the equation of the line.

y - y1 = m(x - x1)

y - 1 = 3/2(x - 8)

y - 1 = 3/2x - 12

y = 3/2x - 11

8 meters increased by 25% is how many meters.

Answers

First find 25% of 8
multiply 25/100 or 0.25 by 8. you get 2. This is the same as dividing 8 by 4 (or
8 x 1/4).
Then add that 25%, which is 2, to 8 meters and you get 10 meters
easy peasy :)

hope this helps

Since 25% is 1/4 of 100%, then you do 8/4 and you get 2 and then you do 2 + 8 = 10.
