D) She has a total of $62 in the piggy bank.
Step-by-step explanation:
Jenny has been saving quarters in a piggy bank since she was born.
She decides to add 56 more quarters so that she can buy a $65 phone.
So she has 192 + 56 = 248 quarters currently.
1 quarter is equivalent to $0.25
248 quarters equals;
× $0.25 = $62
So Jenny has a total of $62 in the piggy bank.
Answer:
x³/4z²
Step-by-step explanation:
Invert and multiply:
48x^5y²/12z^5 x z³/16x²y²=
(48x^5y²)(z³)/(16x²y²)(12z^5)
the y² cancel out
48÷16=3 (on top)
x^5÷x²=x³
12z^5/z³=z²(on bottom)
This leaves a 3x³ on top and 12z² on the bottom. 3÷12=4 (on bottom):
3x³/12z²
x³/4z²
Answer:
○ sin 15° = sin 30°⁄2 = ±√[1 - cos 30°\2]
Step-by-step explanation:
According to the Sine Half-Angle Identity, this is the formula:
sin x = sin ˣ⁄2 = ±√[1 - cos x\2]
Notice the <em>-</em><em>cos</em><em> </em><em>x</em><em>\</em><em>2</em><em> </em>inside the radical. The second option nearly resembles this option. It has a positive symbol inside. Do not let this confuse you. The Cosine Half-Angle Identity is the formula that has a positive in the radical:
cos x = cos ˣ⁄2 = ±√[1 + cos 30°\2]
