<em>The answer is Ms Hernandez can bring up to 6 people to the zoo.</em>

<em />

<em>x -  the number of people that she can bring to the zoo</em>

<em>The parking will cost $7: a = 7</em>

<em>Admission tickets will cost $15.50 per person: b = 15.50x</em>

<em>She can spend on parking and admission tickets $100:</em>

a + b ≤ 100

a = 7

b = 15.50x

7 + 15.50x ≤ 100

15.50x ≤ 100 - 7

15.50x ≤ 93

x ≤ 93 / 15.50

x ≤ 6

The angle of inclination from the base of skyscraper A to the top of skyscraper B is approximately 13.713.7degrees°. If skyscrap
Norma-Jean [14]

Answer:

  5956 ft

Step-by-step explanation:

If we designate the points at the bases of the skyscrapers as A and B, and the top of skyscraper B as point T, then triangle ABT is a right triangle with angle B = 90° and angle A = 13.7°.

The definition of the tangent function tells us ...

  tan(A) = BT/AB

Solving for AB, we find ...

  AB = BT/tan(A) = (1452 ft)/tan(13.7°)

  AB ≈ 5956 ft

The skyscrapers are about 5956 feet apart.

The required equation is:

a = 2b-3

Step-by-step explanation:

Given

Let a be Anne's Age

and

b be Betty's age

Now we will onvert the given word problem in the form of equation step by step

"twice Betty's age." will be represented by 2b

Then

"3 years younger than twice Betty's age."  will be represented as: 2b-3

Now

"Betty's sister, Anne, is 3 years younger than twice Betty's age."

a = 2b-3

Hence,

The required equation is:

a = 2b-3
