Atriangular parking lot has two sides that are the same length and the third side is 5 m longer. if the perimeter is 71 m, find the lengths of the sides.

22m, 22m, 27m

Step-by-step explanation:

The three sides can be noted as: x, x, and x + 5

x + x + x + 5= 71

3x + 5 = 71

3x = 66

x = 22

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
