Since they meet at the $105 mark the answer would be $105
Answer:
4 kg of sugar would contain
crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x

Solve for x. Cross multiply.



Divide both sides by 3


4 kg of sugar would contain
crystals.
Answer:
1. Slope at a=2 is 2.
2. Slope at a=0 is 2.
Step-by-step explanation:
We need to find the slope of y = f(x) at x = a.
1.
The given function is

It can be written as

Differentiate with respect to x.

Substitute x=2 to find the slope of y = f(x) at a=2.



Therefore the slope of function at a=2 is 2.
2.
The given function is

It can be written as

Differentiate with respect to x.

Substitute x=0 to find the slope of y = f(x) at a=0.



Therefore the slope of function at a=0 is 2.
Answer:
$ 10.50
Step-by-step explanation:
we can use a proportion to answer this question
25 : 100 = x : 7
x = (25 * 7)/100 = $1.75 (value of the discount)
Final price = 7 - 1.75 = $5.25
she bought two = 5.25 x 2 = $10.50
