2x = 84/14
Simplify:
2x = 6
Divide both sides by 2 and your answer is....

PLEASE HURRY WILL GIVE BRAINLIEST A truck can be rented from Company A for $90 a day plus $0.30 per mile. Company B charges $70

rjkz [21]

Answer:

40 miles a day

Step-by-step explanation:

The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:

A: 90 + 0.30·40 = 102

B: 70 + 0.80·40 = 102

<h3>Given:</h3>

Trapezium

Length of BC
Value of "x"

<h3>Solution:</h3>

We can divide the given shape into a triangle and a rectangle.

We'll have to use Pythagoras Theorem.

$\large\boxed{Formula:{a}^{2}={b}^{2}+{c}^{2}}$

In this question we have to find the hypotenuse so we'll have to add.

Let's substitute the values according to the formula.

$BC= {6}^{2}+{7}^{2}$

$BC= 85$

$BC = \sqrt{ 85}$

$\boxed{BC=9.22 \: cm}$

Now, we can find the value of "x"

Adjacent= 7 cm
Opposite= 6 cm
Hypotenuse= 9.22 cm

We can use any one from SOHCAHTOA.

Here I'm using tan.

$\large\boxed{Formula: tan(a)= \frac{opp}{adj}}$

Let's substitute the values according to the formula.

$tan \: x= \frac{6}{7}$

We'll have to use tan inverse.

$x= {tan}^{-1}(\frac{6}{7})$

$\boxed{x=40.6°}$

What is the value of h?

baherus [9]

The value of x can be found by adding the two angles and setting them equal to 180 because they are on a straight line.

3h + 18 + 15h = 180
18h + 18 = 180
18h = 162
h = 9

So the value of h is 9

Bob and Roberta are married and have two children. They are covered by a comprehensive medical and major medical policy with a $

Novay_Z [31]

Answer:

Bob will have to pay $2,160 to cover the cost of his surgery

Step-by-step explanation:

Coinsurance on the surgery = 20% * $35,000

Coinsurance on the Surgery = 20/100 * $35,000

Coinsurance on the Surgery = 0.2 * $35,000

Coinsurance on the Surgery = $7,000

Annual Stop Loss = $3,000

Annual Physical Exam costs = $250 * 4

Annual physical Exam = $1000

Coinsurance on physical exam = 80% * $1,000

Coinsurance= 80/100 * $1,000

Coinsurance = 0.8 * $1,000

Coinsurance = $800

Deductible paid for Physical Exam = 20% *$200

Deductible = 20/100 * $200

Deductible = 0.2 * $200

Deductible = $40

Total payables = Annual Loss - Coinsurance on Physical Exam - Deductible for Physical Exam

Total Payables = $3,000 - $800 - $40

Total Payables = $2,160

The insurance company will pay the rest of the medical expenses.
