1. A tourist sights the Hancock tower from the highway with an angle of elevation of 12°. If the

Hancock tower is known to be 1350 feet high, how far away is the tourist, to the nearest tenth?

Answers

Answer: [tex]6351.25\ ft[/tex]

Step-by-step explanation:

Given

Angle of elevation [tex]x=12^{\circ}[/tex]

Height of tower [tex]h=1350\ ft[/tex]

Suppose tourist is d feet away from the tower

from the figure, we can write

[tex]\Rightarrow \tan 12^{\circ}=\dfrac{1350}{d}\\\\\Rightarrow d=\dfrac{1350}{\tan 12^{\circ}}=6351.25\ ft[/tex]

Thus, the distance of tourist from the tower is [tex]6350.25\ ft[/tex]

Answers

Answer:

∡b = 53°

∡d = 127°

∡c = 127°

Step-by-step explanation:

in trapezoids, the two top angles are equal and the two bottom are equal

also, there are 360 degrees in any 4-sided polygon

53 + 53 + x + x = 360

2x + 106 = 360

*Commission Charged
$ £ €
Nancy changes $759.80 and €342 into pounds sterling.
The Post Office deducts their commission and gives Nancy £827.20
What is the percentage commission?​

Answers

Answer:

6% commission

Step-by-step explanation:

Exchange Rates

£1:$1.31

£1 : €1.14

$759.80 to pounds sterling :

£1 = $1.31

x = $759.80

Cross multiply :

x = 759.80 / 1.31

x = £580

£1 = €1.14

x = €342

Cross multiply :

x = 342 /1.14

x = £300

Total = £(580 + 300) = £880

Amount deducted = commision = £880 - £827.20 = £52.80

Percentage commission :

(52.80 / 880) * 100%

0.06 * 100%

= 6% commission

Step-by-step explanation:

The question asks for the ratio of ladybugs to total insects. We'll use "l" for ladybugs and "i" for insects. So, the ratio will be l:i.

The number of ladybugs is 2, so we can plug that into our ratio.

2:i

Now, plug in the total number of insects, which is 6.

which set of ordered pairs could be generated by an exponential function

Answers

Answer:

Option C represents an exponential function

Step-by-step explanation:

Generally, we have an exponential function in the form ;

y = a.b^x

Where in fact, a is not 0

In this case, let us have a as 1 and b as 2

So we have;

for x = -1

y = 2^-1 = 1/2

for x = 0

y = 2^0 = 1

for x = 1

y = 2^1 = 2

for x = 2

y = 2^2 = 4

So the correct choice here is the third option

one electrician charges a $50 service call fee plus $25 per hour for labor. Another electrician charges a $35 service call fee plus $27.50 per hour for labor. how long would a job take if the total cost for each electrician is the same?​

Answers

Answer:

The answer would be 6.

Step-by-step explanation:

First, we need to make equations for these electricians fee's.

Electrician one: Y=25x+50, 50 is the upfront cost and 25 is the cost per hour for work.

Electrician two: Y=27.50x+35, It is the same thing for these numbers.

Then you need to incert numbers into the X place. Y will be your answer.

Y=25(6)+50, Y=150+50, Y=200

Y=27.50(6)=35, Y=165+35, Y=200

The answer would be 6. If both the electricians worked for 6 hours each, their prices would be equal.

Answer:

20km

Step-by-step explanation:

we need to find c, which is the hypotenuse of the right triangle.

we know the lengths of the legs, which are given as 16km and 12km

you might notice that 16km and 12km can both be divided by 4, which will then give is 4 and 3.

3,4,5 is a pythagorean triple-(the sums of the squares of 3 and 4 is equal to the square of 5).

The triple can be proved:

3²+4²=5²

9+16=25

25=25

that means the lengths of the triangle is a multiple of the triple 3, 4, and 5

so that means that c is 5*something

since 12 and 16 are 3*4 and 4*4 respectively, that means that c must be 5*4=20km

Hope this helps!
