Answer:

42 yards

Step-by-step explanation

There are 4 sides to a rectangle. 2 lengths, and 2 widths. That means that you multiply both values by 2 and then add them together, so 40 + 2. A more basic way to think of it is 20+20+1+1. Therefore, the perimeter is 41 yards.

What is the value of x?

Gwar [14]

Answer:

Step-by-step explanation:

First count the number of sides. There are 6 sides.

Now use the formula

(n - 2) * 180 To determine the total of all 6 angles.

(6 -2) * 180 =

4 * 180 = 720

Is that a 9 in x + 9 [lower left]? I'll assume so. Edited to show it was a 4.

x + 4 + 120 + x + 50 + 140 + 112 + x = 720 Combine

3x + 4 + 120 + 50 + 140 + 112 = 720

3x + 426 = 720 Subtract 431 from both sides

3x = 720 - 426 Combine

3x = 294 Divide by 3

x = 294/3

x = 98

The ratio of ages of kissi and esinam is 3:5 and esinam is 3:5 The sum of ages of all 3 is 147 years.whats the age difference be

Sergio039 [100]

Answer:

48 years.

Step-by-step explanation:

Consider the complete question is "The ratio of ages of kissi and esinam is 3:5 and that of esinam and lariba is 3:5. The sum of ages of all 3 is 147 years. whats the age difference between oldest and youngest ?"

It is given that

Kissi : Esinam = 3:5 = 9:15

Esinam : Lariba = 3:5 = 15:25

So, the combined ratio is Kissi : Esinam : Lariba = 9:15:25

Let ages of Kissi, Esinam, Lariba are 9x, 15x and 25x.

Sum of ages of all 3 is 147 years.

$9x+15x+25x=147$

$49x=147$

$x=3$

The value of x is 3. So, the age of all three are

$Kissi=9x=9(3)=27$

$Esinam=15x=15(3)=45$

$Lariba=25x=25(3)=75$

Since Lariba is oldest and Kissi is youngest, therefore, the difference between their ages is

$75-27=48$

Hence, difference between oldest and youngest is 48 years.

What should your units on your base area calculations be, and why? How is this different from the units on your volume calculati

horsena [70]

Answer:

For area, square unit is used as the area is calculated using two dimensions length and breadth.

For volume, cubic unit is used as the volume is calculated using three dimensions length, breadth and height.

Step-by-step explanation:

Area refers to the space occupied by a two dimensional flat object in a plane. For area, square unit is used as the area is calculated using two dimensions length and breadth.

Volume is defined as the space occupied by the three-dimensional object. For volume, cubic unit is used as the volume is calculated using three dimensions length, breadth and height.
