Answer:

Step-by-step explanation:

so the steps to doing this are as follows :

Subtract the accepted value from the experimental value.

Take the absolute value of step 1.

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%

Which of the following best describes rotational symmetry
Gala2k [10]

Answer: B

Step-by-step explanation:

A best describes the quality of symmetry, not specifically rotational symmetry.

C applies to that of A.

D applies to flipping an image across an axis.

B specifically outlines the symmetry of an object when rotated, thus B would be the most precise answer.

A pennant is shaped like a right triangle with a hypotenuse of 10feet. The length of one side of the pennant is two feet longer
marissa [1.9K]

Answer:

6 ft and 8 ft

Step-by-step explanation:

let x be the length of one leg then (x + 2) is the other leg.

Using Pythagoras' identity in the right triangle, that is

x² + (x + 2)² = 10² ← expand left side and simplify

x² + x² + 4x + 4 = 100 ( subtract 100 from both sides )

2x² + 4x - 96 = 0 ( divide all terms by 2 )

x² + 2x - 48 = 0 ← in standard form

(x + 8)(x - 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 8 = 0 ⇒ x = - 8

x - 6 = 0 ⇒ x = 6

But x > 0 ⇒ x = 6

Thus the 2 sides are 6 ft and x + 2 = 6 + 2 = 8 ft

Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each. He handed out 2/3 of the cho
Gnom [1K]

Answer:

Rasheed bought 3 packages of chocolate and 5 packages of toffee.

Step-by-step explanation:

In this case we have to found the number of bars that multiplied by the fractions presented give us an integer number and meets with the fact that the bars are an odd number because the packages came in packs of two bars.

For the case of the chocolate we have to find a number that meets this characteristics, we try with the number 6:

6*\frac{2}{3} =4

For chocolate Rasheed bought 3 packages, we can see that 6 bars meet the asked.

For the case of toffee, we try with number 10:

10*\frac{3}{5} =6

For toffee Rasheed bought 5 packages, we can see that 10 bars meet the asked.

Rasheed bought 3 packages of chocolate and 5 packages of toffee.
