Answer:

c=0.5 cm

Step-by-step explanation:

Angle C is 15 and angle B is 105

The value of b=2cm

We need to find out 'a'

\frac{sin A}{a} =\frac{sin B}{b} =\frac{sin C}{c}

\frac{sin B}{b} =\frac{sin C}{c}

\frac{sin 105}{2} =\frac{sin 15}{c}

cross multiply it

sin(105) c= sin(15) * 2

Divide both sides by sin(105)

c=\frac{sin(15)*2}{sin(105)}

c=0.5

Answer:

c = 0.5 cm

Step-by-step explanation:

Law of sines:

sin (15) / c = sin(105) / 2

0.2588 / c = 0.9659 / 2

c = 0.2588 * 2 / 0.9659  

c = 0.5 cm

What is 2/5 divided by 5/7 in fraction form, not decimal
PIT_PIT [208]
Ok. In order to do this set up 2/5 divided by 5/7. The way you divide with fractions is by multiplying them but flipping the second fraction into 7/5 <---this is known as the reciprocal. In other words do:

2/5 x 7/5 =
14/25
There you go.

The choir is selling candy bars to raise money for a trip they sell each candy bar for $5 there are 7 candy bars in each box and
Reika [66]

Answer:$2800

Step-by-step explanation: Lets first figure out how much money a box of candy bars is worth. We know that each candy bar is worth $5 and that there are 7 candy bars per box. We can multiply 7*5 to figure out that each box is worth $35.

Now lets figure out how many boxes can be sold each day. Each student can sell two boxes a day. 5 students selling 2 boxes each is 5*2= 10 boxes total sold a day.

Now finally we use what we found to figure out the amount of money made per day. We know that there are 10 boxes being sold and that each box makes them $35. We just multiply 10 boxes by $35 to get $350 dollars each day.

Since they sell for 8 days we just multiply 8*$350 to get $2800.

Answer:

f(x) = -8

Step-by-step explanation:

f(x) = x² + 2x – 8

f(x) = (-2)² + 2(-2) – 8

f(x) = (-2)² + 2(-2) – 8

f(x) = 4 + (-4) – 8

f(x) = 4 – 4 – 8

f(x) = 0 – 8

f(x) = -8

I hope this helps

I need help now I don't get this
Darina [25.2K]
The answer is $1.80.  You would take 25% of 3, which is 75, and subtract it from 3.  That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25.  That leaves you with a grand total of $1.80.  Hope that this helped!
