Step one: multiply and divide in order.
Step two: add and subtract like terms.
Step three: get X alone on one side (what you do to one side you have To do to the other side)
Step four: simplify and solve :)
Answer:
The answer to your question is shortest ladder = 6 ft, middle ladder = 12 ft, longest ladder = 24 ft.
Step-by-step explanation:
Data
Ladder 1 = x/2
Ladder 2 = x
Ladder 3 = 2x
Total length = 42 ft
Process
1.- Sum the length of all ladders and solve for x
x/2 + x + 2x = 42
Least common factor = 2
(x + 2x + 4x)/2 = 42
Simplify
7x/2 = 42
7x = 42(2)
7x = 84
x = 84/7
x = 12
2.- Find the length of the ladders
Ladder 1 = 12/2 = 6
Ladder 2 = 12
Ladder 3 = 24
Answer: no
Step-by-step explanation:
She needs a little less than 4 pounds to make 12 turkey burgers because 1/3 times 12 is about 3.99 pounds. But she only has 3 3/8 pounds which is about 3.375 pounds.
Answer:
The maximum height is:
The ball reaches the ground in 1.79 s.
Step-by-step explanation:
We need to take the derivative and equal to zero to find the time at the maximum height.
(1)
Now, we just need to put t(max) into equation (1) to find h(max)
If we want to get the time when the ball reaches the ground we just need to equal h(t) to zero.
Let's solve this quadratic equation.
We will get two solutions and we must choose the positive value.
t1 = 1.79 u
t2 = -0.10 u
Therefore, the ball reaches the ground in 1.79 u.
I hope it helps you!
25% means 0.25 (It also means 1/4.)
50% means 0.5 (It also means 1/2.)
0.25 of 30.44 = 7.61
0.5 of 13.50 = 6.75
From 7.61, subtract 6.75.
OK. I did it. The question just says "do it". It doesn't ask us what the result is.
If anybody asks you, you can do the subtraction, or just tell them it's 0.86 .
(Is that 86 pence?)
