Answer:
AC = 18 ft
Explanation:
There is a geometric theorem that states that:
" In a triangle, the line joining two midpoints of two sides is parallel to the third side and equals have its length"
Now, let's check the given triangle:
M is the midpoint of AB
N is the midpoint of BC
Based on the above theorem:
MN will be parallel to AC
and
length of MN = (1/2) * length of AC
We are given that:
length of MN = 9 ft
Therefore:
9 = (1/2) * length of AC
length of AC = 2 * 9 = 18 ft

Answer:
80 ounces water
60 ounces brine
Step-by-step explanation:
Let x be the amount of water
Let y be the amount of brine 35%
The goal is to have salt weight of 140(0.15) = 21 oz.
21 = 0.35y
y = 60 oz
x = 140 - 60 = 80 oz
The value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The expression is:
= 13(a×b + a²) + 4
Plug a = 5
b = -3
= 13(5×(-3) + 5a²) + 4
= 13(-15 + 5(25)) + 4
= 13(-15 + 125) + 4
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
= 13(110) + 4
= 1430 + 4
= 1434
Thus, the value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.

Answer:
3/4 a pan
Step-by-step explanation:
2 - 1 1/4 = 3/4
two seperated into fourths would look like this
1/4 1/4 1/4 1/4
1/4 1/4 1/4 1/4
one seperated into fourths would look like this
1/4 1/4 1/4 1/4
so take one and one extra fourth away from two and you're left with
1/4 1/4 1/4
add that together and you have 3/4
