Use this equation: P*r*t. Plug in the percentage, rate, and time (years) to solve for your interest! It's a simple problem and It would be good if you used that equation for these problems. Hope it helps!

Help Me5k = 6k + 4 - 6
vagabundo [1.1K]

Answer:

k = 2

Step-by-step explanation:

5k = 6k + 4 - 6

We can simplify this by solving 4 - 6 (replacing it with -2 !)

5k = 6k - 2

Now we can subtract 5k from both sides.

0 = k - 2

Finally, we can add 2 to both sides. This gets rid of the negative 2 on the right.

2 = k

Just reversing it...

k = 2

Answer: k = 2

Samantha saw two bottles of ketchup at the store. One bottle contained 4 pints while the other contained 1.25 quarts of ketchup.
Misha Larkins [42]

Answer:

The first bottle has 4 pints or 8 cups or 2 quarts.  The seconds has 1.25 quarts or 5 cups or 2 1/2 pints.  The one with 4 pints would have more so it would be a better deal.

Find the exact value
ivann1987 [24]

Answer:

A

Step-by-step explanation:

cos~ \theta=\sqrt{1-sin^2 \theta} =\sqrt{1-(\frac{1}{2})^2 } =\frac{\sqrt{3} }{2} \\1+cos~\theta=2cos^2\frac{\theta}{2} \\1+\frac{\sqrt{3}}{2} =2~cos^2 \frac{\theta}{2} \\cos^2\frac{\theta}{2} =\frac{2+\sqrt{3}}{2 \times 2} \\cos \frac{\theta}{2} =\frac{\sqrt{2+\sqrt{3}}}{2} \\1-cos \theta=2 ~sin^2\frac{\theta}{2} \\1-\frac{\sqrt{3}}{2}=2~sin^2 \frac{\theta}{2} \\sin^2 \frac{\theta}{2} =\frac{2-\sqrt{3} }{2 \times 2} \\sin \frac{\theta}{2}=\frac{\sqrt{2-\sqrt{3} } }{2}

as 0≤θ≤90

so θ/2 is also in 0≤θ≤90

hence sin θ/2 and cos θ/2 are positive.
