This is my go at the problem.
Let x be the original price.
72/100=6/100 of x.
so,
x=72/100 ÷ 6/100= $12.00
The answer is $12.00
Hope this helps!
2.4*x/2=34.68
2.4*x=69.36
x=28.9
(x is the height)
Answer: SR ≅ UT
Step-by-step explanation:
Process of elimination:
1) RT ≅ TR doesn't help because RT and TR are the same line.
2) RU ⊥ TU doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠TUR is a right angle (which is already given).
3) SR ⊥ ST also doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠RST is a right angle (which is already given).
4) The statement that SR ≅ UT tells us that ΔRST and ΔTUR are right triangles and have a hypotenuse and leg in common (both triangles share a hypotenuse, RT, both triangles have a 90 degree angle, and SR ≅ UT). If SR ≅ UT, we can prove ΔRST ≅ ΔTUR by using the HL triangle congruence theorem.
Let the three consecutive odd numbers be x,x+2,x+4.
Given, their sum =219
Therefore, x+x+2+x+4=219
⇒3x+6=219
Subtract 6 from both the sides,
⇒3x+6−6=219−6
⇒3x=213
⇒x=71
The other numbers are x+2=71+2=73 and x+4=71+4=75.
Therefore, threee odd numbers are 71,73 and 75.
You are given
a distance of 20 kilometers and time of 30 minutes. You are required to find
for the speed of the travelling object. The equation for speed is distance over
time. Speed is a scalar quantity. It tells you the direction of the travelling object.
The solution in this problem is,
Speed =
distance/time
Speed = 20
kilometers / 30 minutes
<u>Speed =
2/3 kilometers per minute or 0.667 kilometers per minute</u>
<span>Therefore,
the speed of the object is 0.667 km per minute.</span>
