The diagram below shows the shape of the pool at Tori's house. Tori wants to out a fence all around the pool
The expression for the perimeter of the pool is 8x + 20 and the cost of fencing the pool is 27.76x + 69.4
How to complete the missing sides?There are two missing sides in the figure, and they can be calculated using the subtraction operation.
The equations to calculate the missing sides are:
Missing side 1 = 5x - 2 - (-6 + 4x)
Missing side 2 = 12 - x - (3x - 3)
Evaluate the equations
Side 1 = x + 4
Side 2 = 15 - 4x
Hence, the missing sides are x + 4 and 15 - 4x
The perimeter of the poolThis is the sum of the side lengths of the pool.
So, we have:
Perimeter = 5x - 2 + 12 - x - 6 + 4x + 3x - 3 + x + 4 + 15 - 4x
Collect like terms
Perimeter = 5x - x + 4x + x - 4x + 3x - 2 + 12 - 6 - 3 + 4 + 15
Evaluate
Perimeter = 8x + 20
Hence, the perimeter of the pool is 8x + 20
An equation to solve for xIn (b), we have:
P = 8x + 20
Where P represents the perimeter of the pool
The cost of fencing the poolThe cost of fencing the pool is the product of the perimeter and the unit cost per foot.
So, we have:
C = (8x + 20) * 3.47
Expand
C = 27.76x + 69.4
Hence, the cost of fencing the pool is 27.76x + 69.4

Answer:
x = 61°
Step-by-step explanation:
(2x + 3)°+ (x - 6)° = 180°
2x + x + 3 - 6 = 180°
3x - 3 = 180°
3x = 180° + 3
3x = 183°
x = 183°/3
x = 61°

2.
what is the middle between 2 numbers (any numbers, really) ?
you add both numbers and divide the result by 2.
the same here :
(-3 + 24) / 2 = 21/2 = 10 1/2
proof :
what is the distance from -3 to 10 1/2 ? it is 10 1/2 from 0 to 10 1/2 plus 3 from -3 to 0 = 10 1/2 + 3 = 13 1/2.
what is the distance from 10 1/2 to 24 ? it is 13 from 11 to 24, and another half from 10 1/2 to 11. so, in total 13 1/2.
both distances are equal, so it is proven for 10 1/2 to be the midpoint.

Answer:
α = 3π/2
Step-by-step explanation:
To find the coterminal angle, add multiples of 2π until you have an angle in the desired range. Here, you need to add 8π.
α = -13π/2 + 8π = (-13 +16)π/2 = 3π/2

Answer:
275.
Step-by-step explanation:
The gradient of the graph is 70/2 = 35 and it passes through the origin so we can write its equation as
y = 35x.
The gradient of the function represented by the the table is
(240-180) / (4-3) = 60
Ehen x = 3 y = 180 so when x = 0 y = 180 - 60 - 60 - 60 = 0 and the equation of this function is
y = 60x.
For the first equation when x = 11, y = 35*11 = 385.
For the second it is 60 * 11 = 660
So our answer is 660 - 385
= 275

Answer:
[tex]\huge\boxed{\sf x > -1.25}[/tex]
Step-by-step explanation:
Given inequality:0.2 (x + 20) - 3 > -7 - 6.2x
Distribute
0.2x + 4 - 3 > -7 - 6.2x
0.2x + 1 > -7 - 6.2x
Add 6.2x to both sides
0.2x + 6.2x + 1 > -7
6.4x + 1 > -7
Subtract 1 to both sides
6.4x > -7 - 1
6.4x > -8
Divide 6.4 to both sides
x > -8/6.4
x > -1.25
[tex]\rule[225]{225}{2}[/tex]
Answer:
x > -1.25
Step-by-step explanation:
Using the distributive property: a(b + c) → ab + ac
1. Distribute '0.2'
0.2(x) + 0.2(20) - 3 > -7 - 6.2x
0.2x + 4 - 3 > -7 - 6.2x
0.2x + 1 > -7 - 6.2x
2. Add '6.2x' to both sides
0.2x + 6.2x + 1 > -7 - 6.2x + 6.2x
6.4x + 1 > -7
3. Subtract '1' from both sides
6.4x + 1 - 1 > -7 - 1
6.4x > -8
4. Divide both sides by '6.4' to isolate the variable
6.4x ÷ 6.4 > -8 ÷ 6.4
x > -1.25
Final answer: x > -1.25

SOLVE THE TRIANGLE
The third angle of the triangle will be ∠B = 71°.
What is an angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that:-
Two angles are ∠A = 42° and ∠C=67°The third angle will be calculated as:-
∠A + ∠C + ∠B = 180
42 + 67 + ∠B = 180
∠B = 180 - 42 - 67
∠B = 71°
Therefore the third angle of the triangle will be ∠B = 71°.

Answer:
D
Step-by-step explanation:
Whatever angle you pick the three possibilities must add to 180.
a) adds to 150
b) 32 + 59 + 79 = 170. Close but not close enough
c) c has three 5s. The total will end in 5. Not the answer.

a.30°, 90°, 30°
b.32°, 59°, 79°
c.35°, 65°, 75°
d.22°, 37°, 121°
Explanation -:In this question we are asked to find out which one could be the measures of the interior angles of a triangle. Add the three measure angles given if you get 180° then those angles can be the interior angles of a triangle.
We know that,
[tex] \bull \: \small\boxed{ \rm{ Sum \: of \: all \: interior \: angles \: of \: a \: triangle = 180°}}[/tex]
a) 30°, 90°, 30°
→ 30° + 90° + 30° = 180°
→ 150° ≠ 180°
Option a) is not the correct answer.
b) 32° , 59° , 79°
→ 32° + 59° + 79° = 180°
→ 170° ≠ 180°
Option b) is not the correct answer.
c) 35° , 65° , 75°
→ 35° + 65° + 75° = 180°
→ 175° ≠ 180°
Option c) is not the correct answer.
d) 22° , 37° , 121°
→ 22° + 37° + 121° = 180°
→ 180° = 180°
Hence, opition d) is the correct answer
