Given
A tea that is 22% jasmine is blended with a tea that is 13% jasmine
Find out the how many pounds of the 22% jasmine tea are used to make 10lb of tea that is 19.3% jasmine.
To proof
Let us assume that the a tea that is 22% jasmine is blended = a
Let us assume that the a tea that is 13% jasmine is blended = b
Total amount of tea made = 10lb
the equation be
a + b = 10
as given
jasmine tea are used to make 10lb of tea that is 19.3% jasmine.
write 22% in the decimal form
= 0.22
write 13% in the decimal form
= 0.13
write 19.3% in the decimal form
= 0.193
than the equation be
0.22a + 0.13b = 0.193 × 10
on simplify
22a + 13b = 193
two equation becomes
22a + 13b = 193 and a + b = 10
multiply a + b = 10 by 13 and subtracted from the 22a + 13b = 193
we get
22a - 13a + 13b -13b = 193 - 130
9a = 63
a = 7lb
put this value in the a + b = 10
we get
7 + b = 10
b = 3lb
Therefore the 22% jasmine tea are used to make 10lb of tea that is 19.3% jasmine is 7 lb .
Hence proved
Answer:
d = 32.893
Step-by-step explanation:
The distance formula is
d = 
now we plug in the x and y
d = 
d = 32.893

- Choice A
- Choice D
- Choice E
- Choice F
So basically everything but choices B and C are functions.
====================================
Explanation:
- A. This is a function as there are no repeated input x values. Each input (x) leads to exactly one output (y).
- B. This is not a function. We have the input 2 lead to more than one output (1 and 4 at the same time)
- C. This is not a function. Similar to choice B, we have multiple outputs for a given input. In this case, x = 20 has more than one output.
- D. This is a function. Any x input will produce only one y output. When graphed, it passes the vertical line test.
- E. This is a function. This graph passes the vertical line test. It is not possible to draw a vertical line through more than one point on the blue curve, so that's what I mean by "passing the vertical line test".
- F. This is a function. At any given hour (x), there is exactly one temperature (y) possible. The thermometer is not going to produce multiple readings at any one specific moment in time.
