42 times
first, you do 2 1/3 times 3, which is 7. That means 7 miles in one week. then, you do the number of miles times the number of weeks. So, that is 7x6 which is 42.
Answer:
sin 15° = 0.2588
Step-by-step explanation:
The half angle formula is:
![\sin{(\frac{x}{2})} = \pm \sqrt{\frac{1 - \cos{x}}{2}}](https://tex.z-dn.net/?f=%5Csin%7B%28%5Cfrac%7Bx%7D%7B2%7D%29%7D%20%3D%20%5Cpm%20%5Csqrt%7B%5Cfrac%7B1%20-%20%5Ccos%7Bx%7D%7D%7B2%7D%7D)
sin 15°
The double of 15º is 30º. First quadrant, so the sine is positive.
![\sin{15} = sqrt{\frac{1 - \cos{30}}{2}}](https://tex.z-dn.net/?f=%5Csin%7B15%7D%20%3D%20sqrt%7B%5Cfrac%7B1%20-%20%5Ccos%7B30%7D%7D%7B2%7D%7D)
Since ![\cos{30} = 0.866](https://tex.z-dn.net/?f=%5Ccos%7B30%7D%20%3D%200.866)
![\sin{15} = sqrt{\frac{1 - \cos{30}}{2}} = \sqrt{\frac{1 - 0.866}{2}} = 0.2588](https://tex.z-dn.net/?f=%5Csin%7B15%7D%20%3D%20sqrt%7B%5Cfrac%7B1%20-%20%5Ccos%7B30%7D%7D%7B2%7D%7D%20%3D%20%5Csqrt%7B%5Cfrac%7B1%20-%200.866%7D%7B2%7D%7D%20%3D%200.2588)
sin 15° = 0.2588
it is D "How many students does Ms. Sabillon have during enrichment because a statistical question isnt a basic question like, do you like strawberries. for how tall are you? it's a specific like question
The height of building is 27 feet
<u>Solution:</u>
Given that,
Height of gate is 3 feet
The gate casts shadow is 5 feet long
Building cast shadow is 45 feet long
Height of building = ?
Let the height of building be "n"
3 feet tall ⇒ 5 feet long shadow
"n" feet tall ⇒ 45 feet long shadow
By cross multiplication we get,
![\begin{array}{l}{3 \times 45=5 \times n} \\\\ {3 \times 9=n} \\\\ {n=27}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B3%20%5Ctimes%2045%3D5%20%5Ctimes%20n%7D%20%5C%5C%5C%5C%20%7B3%20%5Ctimes%209%3Dn%7D%20%5C%5C%5C%5C%20%7Bn%3D27%7D%5Cend%7Barray%7D)
Thus height of building is 27 feet
Answer:
C
Step-by-step explanation:
144+25=169
the square root of 169 is 13, so the hypotenuse is 13
