Answer:

BT=6.3

Step-by-step explanation:

We have been given that triangle VAT is congruent to triangle BDT. We are asked to find the length of segment BT.

Since both triangles are congruent, therefore, their corresponding sides will be equal by the definition of congruence.

\Delta VAT\cong \Delta BDT

By the definition of congruence:

VA=BD

AT=DT

VT=BT

Since the length of side VT is 6.3 units, therefore the length of BT is 6.3 units as well.

P = 14.7e-0.21x, where x is the number of miles above sea level. To the nearest foot, how high
AlladinOne [14]

9514 1404 393

Answer:

  13064 feet

Step-by-step explanation:

We can rewrite the formula so that x is in feet. Equating the new formula to 8.743 PSI, we have ...

  8.743 = 14.7e^(-0.21x/5280)

Dividing by 14.7 and taking natural logs, we have ...

  ln(8.743/14.7) = -0.21x/5280

Multiplying by the inverse of the coefficient of x gives ...

  x = 5280·ln(8.743/14.7)/-0.21 ≈ 13064.0806

Vanyuwa [196]

Answer:

a. 208.5 ft.

b. 144.9 ft.

Both correct to the nearest tenth.

Step-by-step explanation:

(a) sin 46 = 150 / h where h is the length of the wire.

h = 150/ sin 46

= 208.5 ft.

(b) tan 46 = 150 / x where x is the distance required.

x = 150 / tan 46

x = 144.9 ft.

What will be the cost for 8 hours of work? 10 hours of work?​
andreyandreev [35.5K]

Answer:

<u>Cost = 25 + 50h</u>

cost for 8 hours of work = $425

cost for 10 hours of work = $525

Step-by-step explanation:

The question is as following:

A plumber charges $25 for a service call plus $50 per hour of service write an equation to represent the cost of hiring this plumber​.

what will be the cost for 8 hours of work? 10 hours of work?​

=======================================================

A plumber charges $25 for a service call plus $50 per hour

<u>Cost = 25 + 50h</u>

Where h is the number of hours of service

8 hours of work: h = 8

Substitute with h = 8 at the equation of cost

<u>Cost = 25 + 50* 8 = $425</u>

10 hours of work: h = 10

Substitute with h = 10 at the equation of cost

<u>Cost = 25 + 50 * 10  = $525</u>
