Answer:

Step-by-step explanation:

the ratio of the 2 numbers = 3 : 4 = 3x : 4x ( x is a multiplier ) , then

3(3x) + 2(4x) = 68 , that is

9x + 8x = 68

17x = 68 ( divide both sides by 17 )

x = 4

smaller number = 3x = 3 × 4 = 12

A students home is 3.25 miles from school. A soda shop is located 900 feet farther down the road from school. What is the total

notka56 [123]

1 mile = 5,280 feet.

Convert the 0.25 mile to feet:

0.25 miles = 0.25 x 5,280 = 1,320 feet.

Add the soda shop distance to this:

1,320 + 900 = 2,220 feet.

Total distance is 3 miles and 2,220 feet

Find the exact value by using a half-angle identity. sin(5pi/12)

anzhelika [568]

Find tan(5π12) and sin ((5pi)/12)
Answer: ±(2±√3)and±√2+√32

Explanation:

Call tan ((5pi/12) = t.
Use trig identity: tan2a=2tana1−tan2a
tan(10π12)=tan(5π6)=−1√3=2t1−t2
t2−2√3t−1=0

D=d2=b2−4ac=12+4=16--> d=±4

t=tan(5π12)=2√32±42=2±√3

Call sin(5π12)=siny
Use trig identity: cos2a=1−2sin2a
cos(10π12)=cos(5π6)=−√32=1−2sin2y
sin2y=2+√34
siny=sin(5π12)=±√2+√32
