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.

Step-by-step explanation: Math

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.

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

Roberto and Sandy are playing a rounding game. Roberto says the number 634. Sandy rounds Roberto's number to the nearest hundred. What number does Sandy say?

Answers

The answer would be 600

Reason: If you are rounding up to the nearest hundred then anything 650 or higher, it would be 700 but anything 649 and lower, it would be 600.
It would be 600 because we are rounding to the nearest hundred of 634 so we look to the right and since the three is lest than five we dont round up leaving it 600.
