Suppose Z varies directly with X and inversely with Y where X equals 3Y equals one and Z equals six what is the value of Z when X equals seven and why equals four

Answers

Answer:

k = 2

Z = 3.5

Step-by-step explanation:

Z = kX/Y

Where,

X = 3

Y = 1

Z = 6

Find k

Z = kX/Y

6 = k3/1

Cross product

6 * 1 = 3k

6 = 3k

k = 6/3

k = 2

what is the value of Z when X equals seven and why equals four

X = 7

Y = 4

Z = ?

k = 2

Z = kX/Y

= (2*7)/4

= 14/4

= 3.5

Z = 3.5

For a regular hexagon, the area is 585 cm^2 and the apothem is 13.0 cm. Find the side length, in centimeters, of the hexagon. Round your answer to the nearest whole number.​

Answers

Answer:

Step-by-step explanation:

Area = 1/2 (a * p)

585 = 1/2 (13 * p)

1170 = 13 * p

13*p = 1170

p = 1170/13

p = 90

There are six sides to a regular hexagon. Therefore divide the perimeter by 6.

side = p / 6

side = 90 / 6

side = 15

straight line = 180 degrees so angle opposite a = 180-128 = 52
then triangle adds up to 180 degrees so a= 180-52-73 =55 degrees

Answer:

Take the angle above 128° as x.

x = 180 - 128 (linear pair)

x = 52°

a = ?

a = 180 - ( 52 + 73 ) ( the angles in a triangle add up to 180° )

a = 180 - 125

a = 55°

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

   cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

   cos(x) = [tex]\frac{27}{30}[/tex]

   x = [tex]\text{cos}^{-1}(\frac{9}{10} )[/tex]

   x = 25.84

   x ≈ 25.8°

12). By applying tangent rule in the given triangle,

    tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

    tan(x) = [tex]\frac{43}{18}[/tex]

    x = [tex]\text{tan}^{-1}(\frac{43}{18} )[/tex]

    x = 67.29°

    x ≈ 67.3°

of the 240 students eating lunch, 96 purchased their lunch and the rest brought a bag lunch. What is the ratio of students purchasing
lunch to students bringing a bag lunch?
Oa. 2:5 Ob. 5:2
c3:2 Od: 2:3

Answers

Answer:

96:144

Step-by-step explanation:

Since there are 240 students and the known value is 96 students buying lunch, you simply subtract the two numbers.

240 - 96 = 144

There are 144 students bringing bag lunch.

The ratio is asking students purchasing  lunch to students bringing a bag lunch, which would be 96:144

The simplified answer is 2:3

To get this, divide 144 by 96

This, in turn, would give you in answer of 3/2 which can be inversed to get the right answer
