Can you draw an equilateral right triangle? Explain using precise mathematical language.

Arlecino [84]

Answer:

No.

Step-by-step explanation:

An equilateral triangle is made when all three sides of the triangle are congruent, which means that the angles will also be congruent. A right triangle is defined by its 90° angle. The total angle measures of a triangle add up to 180°. This means that the other two angles have to add up 90° because one measure is already half of 180. Since the measures have to add up to 90, they won't each be equal to 90. This means that the triangle won't be equilateral. (or, you can't have three 90° angles in a triangle because that would pass the 180° measure)

Also, the use of the Pythagorean theorem shows that the sum of the legs squared is equal to the hypotenuse. Thus, the hypotenuse in a right triangle will always be the longest side, which means that it can't be an equilateral triangle.

Mary invests $800 into a high interest savings account. In the first year, the value of her saving increases by 8%. In the secon

g100num [7]

Answer:

The Total value after 2 years=933.12

Step-by-step explanation:

The total value of Mary's investment after two years can be expressed as;

Total value=(Initial investment+Interest)

where;

For the first year,

Initial investment=$800

Interest=Initial investment×interest rate×time

where; Initial investment=800, Interest rate=8%, time=1 year

replacing;

Interest=800×(8/100)×1=$64

Interest=$64

Total value after 1 year=(800+64)=$864

For the second year,

Initial investment=$864

Interest=Initial investment×interest rate×time

where; Initial investment=864, Interest rate=8%, time=1 year

replacing;

Interest=864×(8/100)×1=$69.12

Interest=$69.12

Total value after 2 years=(864+69.12)=$933.12

The Total value after 2 years=933.12
