Alex and Ben were given a total of £360 they shared the money in the ratio 5:7 Ben received more money then Alex.how much more?

Answers

Answer 1
Answer: first
360 divided by 12=30
alex got=30 multiply 5=150
ben got=30 x 7 =210
so ben got 60 more than alex
Answer 2
Answer: 5:7 means that Alex got 5/12 of the whole amount and Ben 7/12.
(5/12)•360=150
(7/12)•360= 210
210-150=60
Ben received £60 more than Alex.
Hope it helps :)

Given EG = 16 and FH = 12, what is the length of one side of the rhombus?

Answers

Length of one side of the rhombus is 10.
If there is a rhombus EFGH, such as yours, with points E, F, G, H (such as in the .jpeg image in attachment), and if the notation of rhombus side is a (rhombus has 4 sides and each of them is of the same length):
FH/2 = 12/2 = 6 (shorter diagonal of rhombus, it's half)
EG/2 = 16/2 = 8 (longer diagonal of rhombus, it's half)
-----------------------------------------
a^2 = (FH/2)^2 + (EG/2)^2
a^2 = 6^2 + 8^2
a^2 = 36 + 64
a^2 = 100
a = square root of 100
a = 10

Instructions:Select the correct answer from each drop-down menu. ABCDEFGH is a regular octagon. The minimum degree of rotation by which this octagon can map onto itself is °. It will take increments of that degree of clockwise rotation for A′ (the image of A) to coincide with C. NextReset

Answers

Answer:

Remember that regular octagon is a figure with eight sides, where all of them are equal. The image attached shows a regular octagon.

So, if we want to map the octagon on to itself using rotation, we need to rotate 90° clockwise, or make to moves of 45° each, that way the octagon would be as the original one because it has equal sides.

When you rotate the first 45°, you would have like an inclined octagon, so you need to rotate another 45° to get the same octagon as the original.

So, the minimum degree would be 45°, doing it twice.
It would be 45 degrees. Since a an octagon takes 8 turns to go around and there is a total of 360 degrees, you can divide 360 by 8 to get your answer of 45 degrees. For answering questions like this you need to take 360 and divide it be the amount of sides to get the minimum amount of degrees of rotation.

Figure ABCD is a parallelogram with point C (−4, 1). Figure ABCD is rotated 90° clockwise to form figure A′B′C′D′. What coordinate would be the output for point C'?

Answers

There are certain rules to follow when rotating a point 90 deg clockwise. Since it is given that ABCD is a parallelogram and the coordinates of point C are given, we just have to follow this simple relation:

R(90 deg) : (X,Y) ---> (-Y,X)

Using the given coordinates:
R(90 deg) : (-4,1) ---> (-1,-4)

Therefore, Point C' will be located at (-1,-4)

Answer:

(1,4)
