Answer:
Pasta: $2.39
Jar of tomato sauce: $3.09
Coupons(-): $0.75+$0.50
Total cost: $4.23
Step-by-step explanation:
The total cost of Barry's purchase is the addition of the cost of purchase of pasta and a jar of tomato sauce, and the value of coupons is reduced from the answer. It would be the final answer.
Answer:
Step-by-step explanation:
The altitude to the hypotenuse of a right triangle create two smaller triangles, all of which are similar to the original. This means corresponding sides are proportional.
3. Using the above relationship, ...
short-side/hypotenuse = 8/y = y/(8+23)
y^2 = 8·31
y = 2√62
__
long-side/hypotenuse = z/(8+23) = 23/z
z^2 = 23·31
z = √713
__
short-side/long-side = 8/x = x/23
x^2 = 8·23
x = 2√46
_____
4. The picture is fuzzy, but we think the lengths are 25 and 5. If they're something else, use the appropriate numbers. Using the same relations we used for problem 3,
y = √(5·25) = 5√5 . . . . . . . = √(short segment × hypotenuse)
z = √(20·25) = 10√5 . . . . . = √(long segment × hypotenuse)
x = √(5·20) = 10 . . . . . . . . . = √(short segment × long segment)
Answer:
-22
Step-by-step explanation:
9-31=-22
Answer:
-2(9+32n)
Step-by-step explanation:
Both the 18 and 64 n are negative, and that is the only answer choice that results in two negative numbers.
