Joyce Goes Walking On A Track Shaped Like The Solid Line In The Diagram Shown. Find The Total Area Enclosed

Answers

Answer 1

Answer:

A

Step-by-step explanation:

πr^2

π * 15^2 = 706.858347

75 X 30 = 2250

706.858347 + 2250 = 2956.858347

Answer 2

The total area enclosed by the track is  2956.5 square meters

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The given figure has one rectangle and two semicircles

The area of rectangle is length times width

Area = length × width

=75×30

=2250 square metres

Area of circle is πr²/2

=3.14×15²/2

=706.5/2

=353.25

As there are two semicircles = 2×353.25

=706.5

Total area is 2250+706.5 which is 2956.5 square meters

Hence,  the total area enclosed by the track is  2956.5 square meters

I need help so I’m so confused

Answers

Answer:

The 4th one.

Step-by-step explanation:

As you know, the length in cm for each is 4, 6, 4, 3, 5, 6, 5, 4, 3, and 6. So, you must now count how many times 4 is listed, which is 3. Now, you will look at each chart for 3 x's above the number 4. You have now eliminated the middle two. Next, count how many 3's there are, which is 2. Both have those, so eliminating other choices is a no-go. Now, look at how many 5's you have, which is 2. Look at your charts... again, no choice ca be marked-off. Finally, look at how many 6's there are, which is 3. So, look at your last options and find which one has 3 total x's above the 6. And there you go, D.

Hope this helps! :)

2. A triangle has two angles measuring 44 and 47. Determine the measure of the third angle.

Answers

Answer: M{x°}=89

A triangle has 3 sides, and the total degree is 180°. So make a equation to find the third degree (x).

44+47=91
180-91=89
so the measure of the 3rd angle is 89

1/2 is the slope. pick 2 points and go up and then over.

Answer:

Slope: [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Slope is : [tex]\frac{rise}{run}[/tex]

If we start at the plotted point (0,0), to travel to the plotted point (2,1) following rise over run pattern you would go up 1 unit for it to correspond the set point and 2 units to the right to reach the exact point.

C: y= 1/50x + 4

Step-by-step explanation:

Since margo drove 200 miles to her aunts house and was left with 8 gallons of gas in the tank of her car when she arrived, we just plug the variables we know in the equation to get the answer. she drove 200 miles, so x=200. 1/50x is 1/50 times 200 aka 4. So now we just add the 4 at the end of the equation and 4 + 4 is 8. This is true, we know she had 8 gallons of gas left when she arrived and she drove 200 miles. So C is the correct answer.

C: 1/50x + 4
Therefore the answer should be C...HOPE I COULD HELP GOOD LUCK:))

Answers

the answer is C) 122.4
Answer:
The area of the triangular case = 61.2 square inches
Step-by-step explanation:
P.S - The exact question is -
Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.
To find - What is the area of the triangular case ?
Proof -
Given that,
Base of triangle = 14 2/5 in
Height of triangle = 8.5 in
We know that,
Area of triangle =1/2 *base *height =1/2 *8.5 *14 2/5
=1/2 * 8.5 * 14.4
=1/2 * 122.4
=61.2

we get
The area of the triangular case = 61.2 square inches
