Answer:
0
Step-by-step explanation:
-4 - -4 = 0
6-4 = 2
0/2 = 0
Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
<span>then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
t</span>he volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50<span>multiply both sides by (10+x) and then simplify
</span>(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8
the answer is
<span>you need to add 8 of a cup of the pure vinegar to the mixture</span>
Answer:
81 units
Step-by-step explanation:
Given data
We are given the function for the height, the height is a function of time t
h=-16t^2+75t
Hence for t= 3 , let us substitute and find the height h
h=-16(3)^2+75(3)
h= -16*9+ 225
h= -144+ 225
h= 81
Hence the height at 3 seconds is 81 units
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25.
Area of the triangle is 112 because the formula for area of a triangle is 0.5•b•h, so .5•16•14= 112
