Answers

Answer 1

Answer: If Alex has spent two lots of 25%, this is equal to 50%, which means he has spent half of his money. If he has $9 left, this means that he has spent $9, meaning that he started with $18. Hope this helps :)

The quadrilateral shown is a rectangle. What is m∠MJN?

A) 24° B) 31° C) 66° D) 90°

Answers

All angles of a rectangle is right angled or 90°.

C) 66°

Given:

∠KJN= 24°

Diagonals in a Rectangle:

The diagonals bisect each other but do not form right angles at the center.
They form linear pairs of angles, obtuse angle + acute angle, as at each of the diagonal.

Thus,

∠MJN+∠KJN=90°

∠MJN = (90-24)°

∠MJN = 66°

Therefore, correct option is C.

Step-by-step explanation:

all the angles of the rectangle are right angle

therefore, angle MJK=90°

∠MJN+∠KJN=90°

∠MJN = (90-24)° = 66°

Which steps would you use to plot the point (7, −6, −5) in a 3-dimensional coordinate system starting from the origin?a. move right 7, down 6, and up 5
b. move forward 7, left 6, and down 5
c. move forward 7, down 6, and left 5
d. move up 7, back 6, and down 5

Answers

Answer:

B. move forward 7, left 6, and down 5

Step-by-step explanation:

By the convention of 3D geometry, the coordinates of a point (x,y,z) represent how far the point is from the origin forward-backward , right/left , up-down respectively with prior one for the positive coordinate and latter for the negative coordinate.

so we need to move forward 7 for x=7 then to left 6 for y=-6 and then down 5 for z=-5.
