Root5 /2 root5 -1
can be written in the form
a+rootb /c
where a, b and c are integers.
Find the values of a, b and c when the resulting fraction
is written in its simplest form.
Answer:
10, 5, 19
Step-by-step explanation:
Recall that
[tex] {a}^{2} - {b}^{2} = (a + b)(a - b)[/tex]
So we can multiply the fraction by
[tex] \frac{2 \sqrt{5} + 1 }{2 \sqrt{5} + 1 } [/tex]
And get
[tex] \frac{ \sqrt{5} }{2 \sqrt{5} - 1} \times \frac{2 \sqrt{5} + 1 }{2 \sqrt{5} + 1 } = \frac{10 + \sqrt{5} }{20 - 1} = \frac{10 + \sqrt{5} }{19} [/tex]

You buy a used car for $12,000. The value of y of the car decreases by 15% each year. Find the value of the car in: a. 1 Year
Step-by-step explanation:
12 000 × 15/100
= $1 800
value of the car = 12 000 - 1 800
= $ 10 200

Find the perimeter of a room with a length of 28 ft. and a width of 19 ft.
Answer:
98 ft
Step-by-step explanation:
28x2 + 19x2
=98
Answer:
Is the room a rectangle size? If so:
28 + 28 = 56
19 + 19 = 38
56 + 38 = 94 ft.
Opposite sides are parallel and equal:
therefore whenever there is two given lengths make sure to multiply them two times then add them together if only its a rectangle.
if its a square make sure to multiply the given length 4 times.

Step-by-step explanation:
Steve reaches into a bag with 5 marbles 3 yellow marbles and 2 green marbles and randomly selects one the he puts the marble back and sam reaches into the same bag and randomly selects a marble is this independent or dependent
Answer:
Independent
Step-by-step explanation:
The reliance of an event on the outcine of another event gives rise to a dependent event. For any two or more event, whereby the outcome of event A has no effect on the possible outcome of event B, then such scenario is termed as being Independent. In the scenario described above, the outcome oof Sam's pick does not depend on the outcine of Steve's pick. This is because, once Steve makes his selection, the marble is returned into the box before Sam makes his own selection.Therefore, no matter the color of marble picked by Steven, it will have no bearing on the outcome of Sam's pick.
Given: BD bisects AE, A = E
Prove: ABC EDC
(No links)
Answer:
All sides are equal better explenation bellow
Step-by-step explanation:
It's a mirror flip of a ABC triangle
Yet you can say AB Is = to DE
And since most likely it's a 60° triangle all the angles are 60°
All triangles have 180°
Which means AB =BC
BC= AC
BC =CD
DE= CD
CE=DE
Which means all the sides are equal
Which is NOT true? 5 + 14 = 20 - 1 9 + 5 = 7 + 7 15 = 4 + 11 15 - 9 = 9 - 4

Answer:
5+14=20 is not true
Step-by-step explanation:

What is the length of AB⎯⎯⎯⎯⎯? Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth. cm A horizontally-aligned scalene triangle A B C. Side A C is labeled as 18 centimeters. Side B C is labeled as 12 centimeters. Angle C is labeled as 79 degrees.
Answer:
AB = 19.6 cm
Step-by-step explanation:
Let AB be represented by c. Applying the cosine rule, we have;
[tex]c^{2}[/tex] = [tex]a ^{2}[/tex] + [tex]b^{2}[/tex] - 2ab Cos C
= [tex]12^{2}[/tex] + [tex]18^{2}[/tex] - 2(12 x 18) Cos [tex]79^{o}[/tex]
= 144 + 324 -432(0.19081)
= 468 - 82.4299
[tex]c^{2}[/tex] = 385.5701
c = [tex]\sqrt{385.5701}[/tex]
c = 19.6359
The side AB of the given triangle is 19.6 centimetres.
Answer:
19.6

What fraction describes the probability for two coins being tossed at the same time to both land on heads?
3/4
1/4
1/2
Answer: 1/4
Step-by-step explanation:
A coin has two outcomes which are either the head or the tail. When a coin is tossed, the probability of getting a head is 1/2 and likewise for a tail.
Therefore, the probability for two coins being tossed at the same time to both land on heads will be:
= 1/2 × 1/2
= 1/4
Answer:
1/4
Step-by-step explanation:
Find the measure of the sixth interior angle of a hexagon if the measure
of the other five interior angles are 80°, 90°, 130°, 130°, and 150°. (Show
all work)
Answer:
140°
Step-by-step explanation:
The sum of interior angles of a n-agon is (n - 2) * 180°
a hexagon should have the sum of angles equal to
4 * 180° = 720°
Now we know that the other five angles have total measure
80° + 90° + 130° + 130° + 150° = 580°
So the sixth one has to be:
720° - 580° = 140°
Answer:140°
Step-by-step explanation: required equation : 180*(n-2)
since it is a hexagon, the sum of all interior angles=180*(6-2)
=180*4 =720°
now the measure of 6th angle=720 -(80+90+130+130+150)
= 720 -580
= 140
