5 × 7

7 + 7 + 7 + 7 + 7= 35

5 × 7 = 35

7 + 7 + 7 + 7 + 7= 35

5 × 7 = 35

This can be treated as a proportion problem.

Larger solid:

Surface area = 1,372 cm²

Volume = 1,801 cm³

Smaller solid:

Surface area = 1,008cm²

Volume = ?

1,372 / 1,801 = 1008 / x

1,372 * x = 1,801 * 1008

1,372x = 1,815,408

x = 1,815,408 / 1,372

x = 1,323.18

The volume of the smaller solid is 1,323.18 cm³

**Answer:**

x > 2y

**Step-by-step explanation:**

It is given in the question that there were more than twice as many adult spectators as children.

If x represents the number of adults and y represents the number of children then inequality representing the relation will be

**x > 2y **

So inequality given above can be used to find the possible combinations of adults and children at the game.

**Answer:**

**Range** defined as the complete set of possible values of the dependent variable,

or

**The range is defined as the resulting y-values we get after substituting all the possible values of x from domain.**

Given the function:

Also, x ∈Domain = {-1, 0, 1, 2, 3}

**For x = -1;**

y = 4(-1)-1 = -4 -1 = **-5**

**For x = 0;**

y = 4(0)-1 = 0 -1 = **-1**

**For x = 1;**

y = 4(1)-1 = 4-1 =**3**

**For x = 2;**

y = 4(2)-1 = 8-1 =**7**

**For x = 3;**

y = 4(3)-1 = 12-1 =**11**

**Therefore, the range of the function are the set of all values of y i,e **

**Range = {-5, -1, 3, 7 , 11}**

2 a + b = 15.7

Since the sides are equal length, the equation is:

**2 · 6.3 + b = 15.7**

We can solve it:

12.6 + b = 15.7

b = 15.7 - 12.6

**b = 3.1 cm**

Since the sides are equal length, the equation is:

We can solve it:

12.6 + b = 15.7

b = 15.7 - 12.6
