A park is shaped like a trapezoid. It has a top base of 1.2 miles and a bottom base of 2.4 miles. If the height is 4 miles, what is the area of the trapezoid?

Answers

Answer 1
Answer:

Answer:

7.2 mi^2

Step-by-step explanation:

A trapezoid is a plane shape and its area isgiven as;

A = (1)/(2) (a + b) h

where a = top base of trapezoid = 1.2 miles

b = bottom base of trapezoid = 2.4 miles

h = height of trapezoid = 4 miles

Hence, the area of the trapezoid shaped park is:

A = (1)/(2) * (1.2 + 2.4) * 4\n\nA = (1)/(2) * 3.6 * 4\n\nA = 7.2 mi^2

The area of the trapezoid shaped park is 7.2 mi^2.

PLEASE ANSWER ASAP: Danielle's wallet had $2.65 in change:all quarters,dimes and nickels. She had 3 times as many quarters as dimes and one more dime than nickels. How many of each coin did she have?SHOW WORK

Answers

We can write an equation in terms of n, the amount of nickels:

25(3n+3)+10(n+1)+5n=265.

Thus:

90n+85=265

Subtracting 85, we have:

90n=180

Therefore, n=2.  As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
2.65=3x(25)+x(10)+(x-1)(5)
9 quarters 3 dimes 2 nickels
9*.25+2.25
3*.10=.30
2*.5=10
2.25+.30+.10=2.65

In the above figure (not drawn to scale), Find ∠AEC. A. 150°
B. 90°
C. 75°
D. 105°

Answers

Answer:

C. 75°

Step-by-step explanation:

We have been given a circle and we are asked to find the measure of angle AEC.

We will use Intersecting chords theorem to find the measure of angle AEC, which states that measure of angle formed inside a circle by two intersecting chords is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

We can see that measure of arc AC is 110 degrees and measure of its vertical arc BD is 40 degrees.

m\angle AEC=(110^o+40^o)/(2)

m\angle AEC=(150^o)/(2)

m\angle AEC=75^o

Therefore, measure of angle AEC is 75 degrees and option C is the correct choice.

Answer : C. 75°

Given : arc length AC=110, CB=20, AD=190, and BD=40

We need to find ∠AEC

The below is the formula for measure of an angle formed by two chords

∠AEC = (1)/(2) ( arc AC + arcBD)

We know arc AC = 110 and arc BD = 40

So ∠AEC = (1)/(2) ( 110 + 40)

= (150)/(2) = 75

∠AEC = 75 degrees

Answer:

  10.5 cm

Step-by-step explanation:

The length of the space diagonal is the root of the sum of the squares of length, width, and height.

  AB = √(5² +6² +7²) cm = √110 cm ≈ 10.488 cm

  AB ≈ 10.5 cm

_____

The space diagonal is the hypotenuse of the right triangle consisting of an edge (L) and the face diagonal of the face perpendicular to that edge. Of course that face diagonal is the root of the sum of squares of the orthogonal edges: √(W² +H²). So, the space diagonal is ...

  AB = √(L² +(√(W² +H²))²) = √(L² +W² +H²)

I have a math worksheet and it asks "what is wrong with camping on the Sahara desert

Answers

Final answer:

Camping in the Sahara desert can be dangerous due to the extreme temperatures, lack of water resources and hazards related to wildlife and weather conditions.

Explanation:

The Sahara Desert is the world's largest hot desert, and can be an incredibly difficult environment to camp in due to extreme temperature fluctuations, lack of water resources, and potential for dangerous weather conditions such as sandstorms. During the day, temperatures in the Sahara can soar above 50°C, and at night they can plummet to near freezing. These temperature extremes can pose a significant threat to human health if one is not adequately equipped or prepared. The desert is also home to a variety of wildlife that can pose hazards, including venomous snakes and scorpions.

Final answer:

Camping on the Sahara Desert is not advisable due to extreme weather conditions, limited resources, and potential risks from wildlife.

Explanation:

Camping on the Sahara Desert may not be an ideal choice for several reasons:

  1. The Sahara Desert is an extremely hot and arid region, with temperatures soaring above 100°F during the day and dropping significantly at night. It can be challenging to find shade and shelter in such harsh conditions, making camping uncomfortable and potentially dangerous.
  2. The vast expanse of sand dunes and limited vegetation in the Sahara Desert make it difficult to find suitable spots for camping, such as flat ground or areas with natural resources like water for cooking and drinking.
  3. The Sahara Desert is home to various wildlife, including scorpions, spiders, and snakes, some of which can be venomous. Camping in such an environment increases the risk of encountering these creatures and the potential for bites or stings.

In summary, camping on the Sahara Desert is not advisable due to extreme weather conditions, limited resources, and potential risks from wildlife.
