Answer:

4.891

its side b (opposite side of the 50 degree angle)

Step-by-step explanation:

side c = 6

angle A is 20 side a (opposite side) = 2.184

angle B is 50 side b (opposite side) = 4.891

angle C is 110 side c (opposite side) = 6

1.

get third angle

50 + 20 = 70

180 - 70 = 110

third angle C is 110

2.

get side a

sin A/a = sin C/c

a/c = sinA/sinC

a = c * sinA/sinC

a = 6 * (sin20/sin110)

get sin in degrees

a = 6 * (.342/.9397)

a = 2.184

Is a diameter of 9cm more than a radius of 5cm and which would have the larger circumference?
Tpy6a [65]

Answer:

Circle B

3.14 cm

Step-by-step explanation:

1. The diameter is twice the radius, so the diameter of Circle B is ...

 2 × 5 cm = 10 cm

This diameter is greater than the 9 cm diameter of Circle A, so Circle B is larger and will have a larger circumference.

2. The circumference is the product of π and the diameter. Then the difference between the two circumferences is ...

... (circle B circumference) - (circle A circumference) = π·(10 cm) - π·(9 cm)

... = π·(10 -9) cm = π·1 cm ≈ 3.14 cm

Nick opens a savings account with $50. Each week after, he deposits $15. He wants to save $500. Write and solve equation to find
Alborosie

Answer:

Equation: 500 = 50 + 15x

Step-by-step explanation:

where x is the number of weeks Nick will have to deposit $15 in order to accumulate $500, given that the first week he deposited $50.  

500 = 50 + 15x

500 = 50 + 15x

450 = 15x

x = 30

 

Now Nick will have to deposit $15 each week for 30 weeks.   This is in addition to the $50 deposit he made week 1.  So it will take him 31 total deposits to accumulate the $500.

A hotel charges a $10,000 annual fee plus an additional $200 for each night you stay there. What is the average cost per night i
Anton [14]

Answer:

\$400

Step-by-step explanation:

GIVEN: A hotel charges a \$10000 annual fee plus an additional \$200 for each night you stay there.

TO FIND: average cost per night if you stay at the hotel for 50 nights.

SOLUTION:

Annual fee charged by hotel =\$10000

amount charged each night we stay there =\$200

Total number of nights we stay =50

Total amount paid for 50 nights=50\times\$200

                                                   =\$10000

Total amount paid =\text{annual fee}+\text{total amount paid for 50 nights}

                              =\$10000+\$10000

                              =\$20000

average cost per night =\frac{\text{total amount paid}}{\text{total number of nights of stay}}

putting values,

average cost per night =\frac{20000}{50}

                                      =\$400

Hence average cost per night if we stay at hotel for 50 days is \$400
