Multiply the first 3 digit numbers by the 2nd pair of 3 digit numbers for example :
3.25x3.12 I think that's what you mean
I will say C 2:1
if your left triangle is the first one, then it is 2
right triangle is 1
for the left triangle is twice as large as the right
Set up a proportion. 3.50 over 5 = x over 1 (x is what we are trying to find= the cost of 1 lb of apples)
Use cross products and multiply 3.50 by 1 to get 3.50 and then divide that by 5 to get 0.7.
So the apple cost 0.7 or seventy cents per pound.
Check: 0.7*5=3.5
That is correct!
Hope this helps!
Can u plz mark me as brainliest? I really need it!
Answer:
0/6 because the arrow start from zero and end at six, remember that the arrow is starting from the vertical axis.....
The value of b^2-4ac is known as the discriminant of a quadratic function, and can tell you how many roots exist of this function depending on what it is equal to.
Start by moving the -1 to the other side, as we need this function to equal zero.
2x^2 + 3x + 1 = 0
This is now the standard form ax^2 + bx + c = 0. Plug each value that corresponds into the discriminant equation.
b^2-4ac
(3)^2 - 4(2)(1)
9 - 8
1
The value of the discriminant is 1, meaning that two real roots exist for the function described.
