Answers

Answer:

350 adult tickets

Step-by-step explanation:

x = adult

x + 52 = children

x + x + 52 = 752

2x + 52 = 752

2x = 752 - 52

2x = 700

x = 700 / 2

x = 350

Hope that helps!

Answer:

a = 350 s = 402

Step-by-step explanation:

s + a = 752 where s is the number of student tickets and a = adult tickets

s = a + 52 since there were 52 more student tickets than adult tickets sold

so substitute for s: (a + 52) + a = 752, so 2a = 700 so a = 350

If adult tickets were 350 then the student tickets are 402

A rectangular piece of paper with length 39 cm and width 20 cm has two semicircles cut out of it, as shown below.Find the area of the paper that remains. Use the value 3.14 for π , and do not round your answer. Be sure to include the correct unit in your answer.

Answers

Answer:

The area of the piece of paper is 466 cm²

Step-by-step explanation:

First you would want to find the area of the rectangle

39x20=780 cm²

Both semi-circles are the same, so you can just find the area of the whole circle

The diameter is 20 cm so you would use 10 as the radius

A=πr²

A=3.14x10²

A=3.14x100

A=314

Then you have to subtract the area of the circle from the area of the rectangle.

780-314=466

The area of the piece of paper is 466 cm²

The Parthenon in Athens, Greece, is an ancient structure that has a rectangular base. The length of the base of the Parthenon is 8 meters more than twice its width. The area of the base is about 2170 square meters. Find the length and width of the base.

Answers

Answer: Length = 70 meters

Width = 31 meters

Step-by-step explanation:

Let the width of the rectangle be x.

Since the length of the base of the Parthenon is 8 meters more than twice its width. This will be: = 2x + 8

Area = 2170

Since length × width = area

(2x + 8) × x = 2170

2x² + 8x = 2170

Divide through by 2

x² + 4x = 1085

x² + 4x - 1085 = 0

x² + 35x - 31x - 1085 = 0

x(x + 35) - 31(x + 35) = 0

(x + 35) = 0 or (x - 31) = 0

x - 31 = 0

x = 0 + 31

x = 31

Width = 31 meters

Length = 2x + 8

= 2(31) + 8

= 62 + 8

= 70 meters

The rectangular base has a length of 70 meters and a width of 31 meters.

Area

Area is the amount of space occupied by a two dimensional object or figure. The area (A) of a rectangle is:

A = length * width

Let w represent the width, hence:

l = 2w + 8

Area = (2w + 8)w

2170 = 2w² + 8w

2w² + 8w - 2170 = 0

w = 31 m

l = 2(31) + 8 = 70 m

The rectangular base has a length of 70 meters and a width of 31 meters.

If your driving 60miles an hour and you drive for 1hour how far do you travel?​

Answers

Answer:

60 miles

Step-by-step explanation:

There are two ways to solve this:

1. They tell you that you drive at 60 miles an hour, so , in an hour, you drive 60 miles.

2. Is the way you should use in the future:

Distance = speed * time

Substitute the speed and times.

Distance = 60 * 1

Thus, you drive 60 miles in one hour

The distance that should be traveled be 60 miles

As we know that

[tex]Speed = \frac{distance}{time}[/tex]

Here

speed be 60 miles per hour

And, the time should be one hour

So, the distance should be

[tex]= 60\ miles\ per hour \times one\ hour[/tex]

= 60 miles

Therefore the distance that should be traveled be 60 miles

What is the equation of the line?

Answers

Answer:

3rd choice

Step-by-step explanation:

y = mx + b

Look at where the line crosses the y-axis. That is the y-intercept. It is 2, so b = 2, and you have

y = mx + 2

Now we need the slope, m.

Start at (0, 2). Go up 1 and right 2.

slope = m = rise/run = 1/2

Now you have

y = 1/2 x + 2

Answer: 3rd choice

Answer:

[tex]c)y=\frac{1}{2}x+2[/tex]

Step-by-step explanation:

[tex]We\ know\ that,\\The\ equation\ of\ a\ graph\ is\ given\ by\ the\ formula:\\y=mx+b,\ where\ m\ is\ the\ slope\ of\ the\ graph,\ and\ b\ is\ the\ y-intercept;\\Here,\\First,\\Lets\ calculate\ the\ slope\ of\ the\ graph:\\We\ also\ know\ that,\\Slope(m)=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}\\Lets\ consider\ any\ two\ points\ which\ lie\ on\ the\ line:\\(2,3),(-2,1)\\Hence,\\The\ slope\ of\ the\ given\ line=\frac{1-3}{-2-2}=\frac{-2}{-4}=\frac{1}{2}\\Hence,\\m=\frac{1}{2}\\[/tex]

Find the answer for m∠EFD

Answers

Given:

In triangle DEF, [tex]DE = EF[/tex] and [tex]m\angle 98^\circ[/tex].

To find:

The measure of angle EFD.

Solution:

In triangle DEF,

[tex]DE = EF[/tex]           (Given)

It means triangle DEF is an isosceles triangle.

[tex]m\angle EDF=m\angle EFD[/tex]           (Base angles of an isosceles triangle are equal)

Using angle sum property in triangle DEF, we get

[tex]m\angle DE F+m\angle EFD+m\angle EDF=180^\circ[/tex]

[tex]98^\circ +m\angle EFD+m\angle EFD=180^\circ[/tex]

[tex]2m\angle EFD=180^\circ-98^\circ[/tex]

[tex]2m\angle EFD=82^\circ[/tex]

Divide both sides by 2.

[tex]m\angle EFD=\dfrac{82^\circ}{2}[/tex]

[tex]m\angle EFD=41^\circ[/tex]

Therefore, the measure of angle EFD is 41 degrees.

A person invests 1500 dollars in a bank. The bank pays 4% interest compounded
annually. To the nearest tenth of a year, how long must the person leave the money
in the bank until it reaches 1800 dollars?

Answers

Answer:

4.6 years

Step-by-step explanation:

We are to calculate the time in years.

The formula is given as:

t = ln(A/P) / n[ln(1 + r/n)]

Where:

A = Amount after t years = 1800

P = Initial Amount invested = 1500

r = Interest rate = 4%

n = Frequency at which the interest was compounded = Annually = 1

First, convert R percent to r a decimal

r = R/100

r = 4%/100

r = 0.04 per year,

Then, solve our equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(1,800.00/1,500.00) / ( 1 × [ln(1 + 0.04/1)] )

t = 4.649 years

Approximately = 4.6 years
