A group of 31 students is going to visit the museum. The total cost for the tickets is $145.15. About how much money will each student need to pay for a ticket?

Answers

Answer:

$4.65

Step-by-step explanation:

each student will need about 5.00$

145.15 divided by 31 = 4.68 but since it says about just round up to the closest dollar so you’ll essentially get 5 dollars

Seven friends have similar cell phone plans. The price of each plan is $x. Three of the seven friends pay an extra $4 per month for unlimited text messaging. Write and simplify an expression that represents the total cost of the seven plans. (Provide expression in simplest form)

Answers

Answer: 7x + 12

Step-by-step explanation:

The price of each plan = $x

Since three of the seven friends pay an extra $4 per month for unlimited text messaging, the cost of the three friends will be:

= 3(x + 4)

The cost if the other four friends will be:

= 4 × x

= 4x

Therefore, the total cost of the seven plans will be:

= 4x + 3(x + 4)

= 4x + 3x + 12

= 7x + 12

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The height of the tree is 39.1027 feet.

What is Tangent (Tanθ)?

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The Base is the adjacent smaller side of the angle θ.

Tan(70°) = Height of the tree/Shadow of the tree

Tan(70°) = Height of the tree/ 32 feet

Height of the tree = 39.1027 feet

Hence, the height of the tree is 39.1027 feet.

Diego has $11 and begins saving $5 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $60 and begins spending $2 per week on supplies for her art class.

Is there a week when they have the same amount of money? How much do they have at that time?

Answers

Answer:

Let x represents the week and y represents the amount of money.

As per the given statement:

Diego has $11 and begins $5 each week toward buying a new phone.

⇒               ......[1]

It is also given that Lin $60 and begins spending $2 per week.

⇒               ....[2]

when they have the same amount.

equate [1] and [2] we get;

Add both sides 2x we get;

Subtract 11 from both sides we get;

Divide both sides by 7 we get;

x = 7

Substitute the value of x = 7 in [1] we have;

Therefore, at x= 7 week they have the same amount of money and they  have the amount at that time, $ 46
