The answer to this problem is 1 and 5 tenths.
Answer:
2.5L of 10% salt solution and 7.5L of the 30% salt solution
Step-by-step explanation:
let the amount of L in the 10% solution be 'x'
let the amount of L in the 30% solution be '10-x'
* because they add up to a total of 10L
10%(x) + 30%(10-x) = 25%(10)
0.1x + 3 - 0.3x = 2.5
-0.2x = -0.5
x = 2.5
x =2.5
10-x = 7.5
2.5 of 10% solution and 7.5% of 30% solution
The earth rotates on an axis , just like when u see the clouds “moving” it’s not the clouds the earth is rotating on its axis. This causes Day and Night. Yes, in your perspective the UFO will be moving although if u were inside the UFO it would appear that the East is moving when it is.
The scale factor that can be applied to Cone 1 to make Cone 2 is 0.8
<h3>What are scale factors?</h3>
This are constants that is used to enlarge of diminish a given figure of sides of a figure
We can determine the scale factor by finding the ratio of the similar sides of two figures, From the given cones, the ratio of their radius can determine the scale factor that is applied to Cone 1 to make Cone 2
From the given figure;
scale factor = radius of cone 2/radius of cone 1
Given the following parameters
radius of cone 2 = 2 ft
radius of cone 1 = 2.5ft
Substitute
scale factor = 2/2.5
scale factor = 0.8
Hence the scale factor that can be applied to Cone 1 to make Cone 2 is 0.8

You can use:
1. LA theorem, because you have
- leg ED is congruent to leg KJ;
- ∠FED is congruent to ∠LKJ.
2. AAS Postulate, because
- side ED is congruent to side KJ;
- ∠FED is congruent to ∠LKJ;
- ∠EFD is congruent to ∠KLJ.
3. ASA Postulate, because
- side ED is congruent to side KJ;
- ∠FED is congruent to ∠LKJ;
- ∠EDF is congruent to ∠KJL.
