Answer: 123
Step-by-step explanation: TO solve problems like this, you should assign a variable to the lowest number, lets just say n. From here, since we know the numbers are consecutive, we can see that the numbers are n, n+1, and n+2. Therefore:
n(first number) + (n+1)(second number) +(n+2) (3rd number) =366
>n+n+1+n+2=366
3n+3=366
3n=363
n=121
n+2=123
Answer:
0.525
Step-by-step explanation:
52.5 * 0.01 = 0.525
Answer:
The question gives you V0 as 220, so plug that in first.
h=-16t2+220t.
Then it says to find the time (solve for t), when the height is 400 ft. Plug 500 ft in as h and solve for t.
500=-16t2+220t.
To solve this, set the quadratic equal to 0 by subtracting 500 from both sides (0=-16t2+220t-500) and use the quadratic formula!
Step-by-step explanation:
<span>(14x^2+21x) = 7x(2x + 3)
A= L * W
but L = 7x so W = </span>2x + 3
<span>
answer: </span><span>width is (2x +3) feet</span><span>
</span>
Answer: The 2/9 should have been simplified to 2/3. Then multiply 1/7 and 2/3 to find the product, 2/21
You have to "simplify" both factors at the same time before moving on to multiplying them.
Step-by-step explanation:
Another way to do this is to multiply straight across 3/7 × 2/9 to get 6/63 then notice that the numerator and denominator are both multiples of 3.
Simplify by dividing numerator and denominator by 3 to get 2/21
