Answer:
21.75 or 21 
Step-by-step explanation:
What I did was 14.5 / 2 to see how many miles were on a 1/3 gallon, then multiplied that answer (which was 7.25) by 3 to get the full 3/3 or 1 gallon.
Answer:
circumference of the cake board = 109.9 cm
Step-by-step explanation:
diameter of cake = 30cm
diameter of cake board = 5cm longer than 30cm = 5 + 30 = 35cm
radius cake board = diameter ÷ 2 = 35 ÷ 2 = 17.5 cm
radius of cake board = 17.5 cm
circumference of a circle = 2 × π × r (where π = 3.14)
circumference of a circle = 2 × 3.14 × 17.5 = 109.9 cm
Therefore the circumference of the cake board = 109.9 cm
Answer:
Someone deleted my answer, which sucks cuz I know there are a bunch of students who pretty much need this so here it goes; the answer is <em>y=5x+3</em>
Step-by-step explanation:
I did this math problem a long time ago, I don't remember how I got the answer, I just have the answer lol
Apples went up 0.75 a lb
p is the start price so new price is p + 0.75
we buy 3 lbs
3 ( p+ 0.75) = 5.88
now solve
3p + 2.25 = 5.88
-2.25 -2.25
3p = 3.63
/3 /3
p = 1.21 a lb
Given, (9x - 4)(9x + 4) = ax² - b
From algebraic identities:
We know, (a + b)(a - b) = a² - b²
Now, 81x² + 36x - 36x - 16 = ax² - b
81x² - 16 = axis² - b
So ax² = 81x²
a = 81
-b = -16
b = 16
Solution
Therefore, the value of a is 81.
