Answer:
163.3m²
Step-by-step explanation:
area = Pi(r²)
r = d / 2
r = 12
12² = 144
144 x 3.14 = 452.16
diameter of bigger circle = 24 + 4 (2 on each side)
28 / 2 = 14
14² = 196
196 x 3.14 = 615.44
sidewalk = bigger - smaller
sidewalk = 615.44 - 452.16
sidewalk = 163.3

X+5 < 6
Pls help
Answer:
x<1
Step-by-step explanation:
You would just subtract 5 from both sides of the equation. The sign does not flip because you are not multiplying or dividing any negative number across the sign. So simply x+5 (-5) < 6 (-5). On the left side the 5 would cancel out. on the other side 6-5 is equal to 1.
Answer: x<1
Answer: x < 1
Step-by-step explanation: x + 5 < 6
Subtract 5 from both sides,
x < 1

Each side of the regular hexagon below has the same measure. A hexagon with side lengths of 2. 5 feet. If a model of the hexagon is made by using a scale factor of 6, which applies to the model? Select two options. The model represents a reduction. Each side of the model is 15 feet long. The model is proportional to the original hexagon. One side of the model can be 8. 5 feet. The scale factor is divided by 2. 5 to get the dimensions of the model.
The correct option for a regular hexagon is b) Each side of the model is
15 feet long. and c) The model is proportional to the original hexagon.
What is a regular hexagon?A regular hexagon is defined as a closed shape consisting of six equal
sides and six equal angles. The sum of the measure of angles of a
regular hexagon is 120 degrees.
It is given that a hexagon with side lengths of 2. 5 feet.
The scale factor is 6.
Since scale factor = new length/original length,
new length = scale factor × original length
= 6 × 2.5 feet
= 15 feet.
Also, each side of the hexagon increases by a constant factor of 6, the model is proportional to the original hexagon.

Given the function g(x)=√x+4, which of the following values cannot be the domain of g?
A. X=1
B. X=2
C. X=12
D. X=-5
Answer:
D. x = -5
Step-by-step explanation:
The square root function is only defined for non-negative arguments. For the function ...
[tex]g(x)=\sqrt{x+4}[/tex]
this means we must have ...
x +4 ≥ 0
x ≥ -4 . . . . . . subtract 4 from both sides
All of the numbers on your answer choice list are more than -4 except -5.
x = -5 is not in the domain of g(x)

Answer:
[tex]884^{-7}[/tex]
Step-by-step explanation:
Start by simplifying the denominator of the fraction. When multiplying exponents of the same base, you can add the exponents. This is also known as the product rule.
[tex]a^x\cdot a^y=a^{x+y}[/tex]
["a" is the base, and "x" and "y" are the exponents]
Using this we find...
[tex]884^{58}\cdot884^{46}=884^{58+46}=884^{104}[/tex]
When dividing exponents of the same base, you can subtract the exponents. This is also knows as the quotient rule.
[tex]a^x\div a^y=a^{x-y}[/tex]
Using this we find...
[tex]\frac{884^{97}}{884^{104}}=884^{97-104}=884^{-7}[/tex]
