Answer:
A 21,000-Btu unit that will cool 340 cubic meters;
Step-by-step explanation:
Calculating the volume of the five rooms, we have;
Room 1:
Volume = 2.4 *4*5
= 48 m³
Room 2:
Volume = 2.4*4*4
= 38.4 m³
Room 3:
Volume = 2.4*6*4
=57.6 m³
Room 4:
Volume = 2.4*6*6
=86.4 m³
Room 5:
Volume = 2.4*6*5.5
= 79.2 m³
Total volume of the room = 48 +38.4 + 57.6 + 86.4 + 79.2
= 309.6 m³
From the total volume obtained above, the air condition that will be adequate to cool the house is 21,000-Btu unit since the obtained volume(309.6 m³) is within the range of the specify volume (340 cubic meters).
Answer:
y = 81°
Step-by-step explanation:
let the 5 th angle in the pentagon be x
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, then
sum = 180° × 3 = 540°
sum the angles and equate to 540
x + 95 + 125 + 116 + 105 = 540
x + 441 = 540 ( subtract 441 from 540 )
x = 99°
x and y are adjacent angles and supplementary, sum to 180° , that is
x + y = 180°
99° + y = 180° ( subtract 99° from both sides )
y = 81°
Answer: 
Explanation:
We plug the given coordinates into the distance formula

There isn't much we can do from there since we don't know the values of 'a' or 'b'. You could expand out each binomial, but it's more simplified being factored like that.
Answer:
w = 3
l = 10
Step-by-step explanation:
l = 4w-2
P = 26cm
P = (l + w) × 2
26 = (4w-2+w) ×2
26 = (4w + w - 2) × 2
26 = ( 5w - 2 ) × 2
26 ÷ 2 = 5w -2
13 = 5w - 2
13 + 2 = 5w
15 = 5w
w = 3
l = 4w - 2
l = (4 × 3) -2
l = 12 - 2
l = 10
2304 cubic inches. You multiply the length, width, and base
