Point B lies between points A and C on Line segment A C . Let x represent the length of segment AB in inches. The length of line
tresset_1 [31]

AB = x

BC = 3x

AC = 20 inches = AB + BC

Let's plug our values into the equation above.

20 inches = x + 3x

Combine like terms

20 inches = 4x

Divide both sides by 4

5 = x

AB = x = 5 inches

BC = 3x = 3(5) = 15 inches

A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Ever
hichkok12 [17]

Answer:

\dfrac{17}{72}

Step-by-step explanation:

From the given information:

Total number of students, n(U)=72

The choices were: Chess(C), Swimming(S), and Football(F).

Everyone liked at least one sport except 7 kids, n( C \cup F \cup S)'=7

Chess is not an active sport; and

10 children liked Chess only, n( C \cap F' \cap S')=10

The probability that a randomly-chosen child from this group does not like active kinds of sport is the Probability that a student plays chess only or like no kind of sport at all.

P( C \cup F \cup S)'+P(C \cap F' \cap S')=\dfrac{n( C \cup F \cup S)'+n(C \cap F' \cap S')}{n(U)} \\=\dfrac{10+7}{72} \\=\dfrac{17}{72}

One angle is eight times it’s supplement increased by 45 degrees. What is the measures of the two supplementary angles?
Nastasia [14]
Angle 1 = 8x + 45
Angle 2 = x

x + 8x  + 45 = 180
combine like terms

9x + 45 = 180
subtract 45 from both sides

9x = 135
divide both sides by 9 to isolate x

x = 15

Angle 1 = 8(15) + 45 = 165 degrees
Angle 2 = 15 degrees
