If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-fifths full?​

Answers

Answer:

3/5 of 30 = (3/5)*30

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.

Express the edge length of a cube as a function of the cube's diagonal length d. Then express the surface area and volume of the cube as a function of the diagonal length.

a. A function for the edge length of a cube is L(d) = _________________
b. A function for the surface area of a cube is Ald) = _____________
c. A function for the volume of a cube is V(d) = ________________

Answers

Answer:

Step-by-step explanation:

If L is the length of a side, the longest diagonal in the cube is

d = √(L² + L² + L²) = √(3L²) = L√3

meaning

a) L(d) = d/√3 = ⅓d√3

b) A(d) = 6(L(d))² = 6(⅓d√3)² = 6(⅟₉d²(3)) = 2d²

c) V(d) = (L(d))³ = (⅓d√3)³ = ⅟₂₇d³3√3 = ⅟₉d³√3

A pool charges $7 for 2 daily pool passes.
Which table could represent the situation?

Answers

Answer:

Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership.

Option B is the table which could represent the given situation.

What is a linear equation?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

According to the question

A pool charges $7 for 2 daily pool passes.

Using the linear equation y = mx + b

Substitute x = 2, y = 7

[tex]7 = 2m + b[/tex].....(1)

Substitute x = 4, y = 14

[tex]14 = 4m + b[/tex]  .....(2)

Using elimination method

Subtract equation 1 from 2

[tex]14 - 7 = 4m - 2m + b - b[/tex]

[tex]7 = 2m[/tex]

[tex]m=\frac{7}{2}[/tex]

Substitute m = [tex]\frac{7}{2}[/tex] in equation 1

[tex]7=2(\frac{7}{2} )+b[/tex]

b = 7 - 7

b = 0

Substitute b = 0 in equation 1

7 = 2m

Similarly

14 = 4m

21 = 6m

28 = 8m

Hence, Option B is the table which could represent the given situation.

The trick is to let the letters =  points of a clock that keeps time this way.

l = 9 oclock

C = 3 oclock

-H= -8

Formula

(x - l) / C = -H

Solution

Substitute the givens into the equation

(x - 9) / 3 = -8                 Multiply both sides of the equation by 3

3*(x - 9)/3 = -8*3            Simplify

(x - 9) = - 24                   Remove  the brackets

x - 9 = - 24                     Add 9 to both sides.

x-9+9 = -24+9               Combine
