After being discounted 40%, a weather radio sells for $35.97. find the original price. (round your answer to the nearest cent.)
tia_tia [17]

It is given in the question that

After being discounted 40%, a weather radio sells for $35.97.

It means the weather radio sells at a 60% of original price.

Let the original price be $x.

Therefore according to the question,

60% \ of \ x = 35.97
\\
0.6x = 35.97
\\
x = $59.95

Therefore the original price of the weather radio is $59.95.

Triangle QRS has the angle measures shown.
galina1969 [7]

Answer:

108 degrees

Step-by-step explanation:

Given the following angle measures in triangle QRS

m<Q = 1x

m<R = 3x

m<S = 6x

Note that the largest angle is the obtuse angle since they are always greater than 90 and less than 180 degrees

The sum of angle in a triangle is 180 degrees

m<Q + m<R + m<S = 180

1x + 3x + 6x = 180

10x = 180

x = 180/10

x = 18

The obtuse angle is 6x

Measure of the obtuse angle = 6x

Measure of the obtuse angle = 6(18)

Measure of the obtuse angle = 108 degrees

Hence the measure of the obtuse angle is 108 degrees

A​ single, six-sided die is rolled. Find the probability of rolling an even number or a number less than 6 .
boyakko [2]

Answer:

P=1

Step-by-step explanation:

P(even or less than 6) = P(even)+P(less than 6) -P(even ∩ less than 6)

P(even)=3/6 (numbers 2,4, and 6)

P(less than 6) =5/6 (numbers 1,2,3,4, and 5)

P(even ∩ less than 6)=2/6 (numbers 2 and 4)

(3/6)+(5/6) -(2/6) = (3+5-2)/6 = 6/6=1
