Yes we can. In Euclidean geometry, two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other. More precisely, one can be obtained from the other by uniformly scaling (enlarging or reducing), possibly with additional translation, rotation and reflection. This means that either object can be rescaled, repositioned, and reflected, so as to coincide precisely with the other object. If two objects are similar, each is congruent to the result of a particular uniform scaling of the other.
If it helped u give a brainliest please:-)
Do it backwards
-9+4=-5
Answer
x= -5
First, let x be the amount of 20% acid solution in liters. With this, 60 - x is the amount of 50% solution. The acid balance before and after mixing becomes,
(0.2)(x) + (0.5)(60 - x) = (0.40)(60)
The value of x is 20. Therefore, Gabe needs 20 liters of 20% acid solution and 40 liters of 50% acid solution.
Answer:
160.9 feet
Step-by-step explanation:
The function h(t) = 200 – 17t represents the height of a ball (in feet) dropped from 400 feet after t seconds.
After 2.3 seconds,
h(t) = 200 – 17t
h(2.3) = 200 – (17 X 2.3)
= 200 - 39.1
=160.9 feet
After 2.3 seconds, the ball drops to a height of 160.9 feet.
So practically, it’s asking you to rearrange the formula to make it equal the value given:
h=A/ 1/2b
w=V/lh
b=A/h
