what is the perimeter, in feet (ft), of a right triangle which has an area of 12 ft^2 and one leg that has a length of 4 ft?

Answers

Answer 1

Answer:

           P = (10 + 2√13) ft ≈ 17.21 ft

Step-by-step explanation:

A = 12 ft²     - area of triangle

a = 4 ft, b    - legs of right triangle

c       - hypotenuse (third side of triangle)

A = ¹/₂ ab

12 =  ¹/₂•4•b

12 = 2b

b = 6 ft

from Pythagorean theorem:

a² + b² = c²

4² + 6² = c²

c² = 16 + 36

c = √52 = 2√13 ft

The perimeter:  P = a + b + c

P = 4 + 6 + 2√13 = (10 + 2√13) ft ≈ 10 + 7.21 = 17.21 ft

which expression can be used to find the surface area of the following square pyramid

Answers

Answer:

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Hope this helps :)

The answer is a 36 + 15 + 15+ 15 +15

Megan wanted 50 beads that were originally $9.95. She had a coupon for 25% off and paid a sales tax of 6%. What was the total she paid for the beads?

Answers

9.95(0.75)(1.06)=7.91

The .75 is the coupon and 1.06 is the sales tax.

If the sales tax is 6%, add the decimal version of 6% to 9.95.

6% ⇒ 0.06

9.95 + 0.06 = 10.01

Since Megan has a 25% off coupon, find 25% of the full price by multiplying 0.25 by 10.01.

25% ⇒ 0.25

10.01 × 0.25 = 2.50

Now subtract 2.50 from 10.01.

10.01 - 2.50 = 7.51

Answer:

The total price of the beads is $7.51.

Hope this helped!

The number 813.1 is a rational number.

It is required to find the 813.1 a rational number or not.

What is real number?

Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.

Given:

Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number.

The given integer is

813.1

=8131/10

The decimal 813.1 is a rational number. First of all, it is a terminating decimal, which means that the decimal has a definite ending point. All terminal decimals are rational numbers. In addition, the decimal 813.1 can be converted to a fraction of 8131/10. Since both 8131 and 10 are integers (whole numbers), this also tells us that it is a rational number.

Therefore, the number 813.1 is a rational number.
