Five fifths are in one whole.
Don't believe me?
So you just do 1÷5
which is 5!

<span>
1/5+1/5+1/5+1/5+1/5= 1 whole
just like 5*5=25, which is a whole factor</span>

Simplify cos^2 A/1+sin A

Stels [109]

Answer:

$\displaystyle \frac{\cos^2(A)}{1+\sin(A)}=1-\sin(A)$

Step-by-step explanation:

We want to simplify:

$\displaystyle \frac{\cos^2(A)}{1+\sin(A)}$

Recall the Pythagorean Identity:

$\sin^2(A)+\cos^2(A)=1$

So:

$\cos^2(A)=1-\sin^2(A)$

Substitute:

$\displaystyle =\frac{1-\sin^2(A)}{1+\sin(A)}$

Factor. We can use the difference of two squares pattern:

$\displaystyle =\frac{\left(1-\sin(A))(1+\sin(A))}{1+\sin(A)}$

Cancel. Hence:

$\displaystyle \frac{\cos^2(A)}{1+\sin(A)}=1-\sin(A)$

What is the rate of A, what is the rate of B, which equation has a greater rate?

11Alexandr11 [23.1K]

Answer: Rate of A: 5/6

Rate of B: 3/5

A has a higher rate of change

Step-by-step explanation: You calculate slope/rate of change by determining the rise over the run. The rate of change in A is 5/6x, this is bigger than the slope of B.

one fruit punch had 40% fruit juice and another is 90% fruit juice. how much of the 40% punch should be mixed with 30 gallons of

sashaice [31]

A = fruit juice 40%

B= 90% juice

then

30 gallons + A = 55• C/100

30 gallons + N • (40/100) = (30 + N)• (55/100)

Now solve this equation, for N

3000 + 40N = (30+N) •55

then

3000 - 1650 = 55N - 40 N = 15N

1350 = 15 N

then

N= 1350/15 = 90

Then answer is

Should be mixed 90 gallons of 40% fruit punch

Please I need help with this problem number 5????

zheka24 [161]

Estimating the area:
$x = (20 \times 8)(13 \times 8) \\ x = 264$
Calculating wallpaper:
$x = (264 \times 1.05) \div 35 \\ x = 7.92 \\ x = 8$
we round up here because they will need a full roll to complete the room. Since they can't buy 7.92 rolls, they must buy 8.

Calculating cost:
$x = 8(31.48) + 31.48(0.0825) \\ x = 254.44$
