A circular pool at a water treatment facility has a radius of 6 meters. Approximately how long is the outer rim of the pool? (Use 3.14 for π.)
a. 40 m b. 60 m c.80 m d.160m
Answer:
Step-by-step explanation:
length of outer rim = circumference = 2π(radius) = 12π meters ≅ 37.68 meters
So none of the choices is correct.

2. If 8.67 is rounded to tenth, 8.67 becomes
A. 8.00
B. 8.7
C. 8.60
D. 86.0
2.64
Answer:
b. 8.7
Step-by-step explanation:
7 rounds up turning the 6 besides it into a 7.
Answer:
B. 8.7
Step-by-step explanation:
When lliking at 8.67 you see that the 6 (in the tenths place) is above five, any number above five, you found so then you round it to 7. if it's 4 or below you round down.
If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the frame be?
Answer:
w = width
h = height
2(w+h) < 200
w + h < 100
since w = 36, then
36 + h < 100
h < 100 - 36
h < 64
Step-by-step explanation:
The perimeter of the rectangular picture frame can be calculated by the equation,
2h + 2w = P
where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,
2h + 2(36 in) < 200
The inequality gives h as,
h < 64
Thus, the answer is letter A.

what’s the perimeter of a rectangle with 6x+10 as it’s width and 4x+1 as it’s length
Answer:
the equation will be 2(6x+10+4x+1)
simplified to
12x+20+8x+2
simplified to
20x+22
The perimeter of the rectangle will be 20x+22
Thank you, Hope it helps
Answer: The length of both sides would be 12x+20 and the width of both sides would be 8x+2, so the perimeter of the rectangle would be 20x+22

What is the relationship between the corresponding angle bisectors BD and XZ?
Answer:
XZ = 2.5 BD
Step-by-step explanation:
Comparing the two triangles,
[tex]\frac{BD}{BC}[/tex] = [tex]\frac{XZ}{XY}[/tex]
[tex]\frac{6}{8}[/tex] = [tex]\frac{XZ}{20}[/tex]
⇒ XZ = [tex]\frac{20*6}{8}[/tex]
= 15
XZ = 15
So that,
BD:XZ = 6:15
= 1:2.5
Therefore, the relationship between BD and XZ is XZ = 2.5 BD.
A quarter cone has a diameter of 16 and a height of 10. What is the approximate volume of the quarter cone? Round to the nearest tenth where necessary.
Answer:
167.6 units^3
Step-by-step explanation:
Find the volume of the entire cone, and then divide the result by 4 to obtain the volume of the quarter cone:
Formula for the volume of a cone is V = (1/3)(base area)(height)
In this case the volume of the entire cone is V = (1/3)(pi)(8)^2*(10), or
670.21.
Taking 1/4 of this, we get the volume of the quarter cone:
670.21/4 = 167.6 units^3
What are the solution(s) to the quadratic equation 40 - x2 = 0?
x = +2/10
x = +4/10
O x= +2/5
x = +4,5
Answer:
±2√10
Step-by-step explanation:
Given the equation 40 - x^2 = 0
Add x^2 to both sides
40 - x^2 + x^2 = 0+ x^2
40 = x^2
x^2 = 40
x = ±√40
x = ±√4 * √10
x = ±2√10
Hence the value of x is ±2√10
Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. The whole trip took 8 Hours. How Far did he travel on the train? Solve algebraically, and round your final answer to one decimal place.
Answer:
523.6 km
Step-by-step explanation:
Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...
time = distance/speed
Then the total travel time in hours is ...
x/160 +(1020-x)/105 = 8
21x +32640 -32x = 26880 . . . . . multiply by 3360
5760 = 11x . . . . . . . . . add 11x -26880
523.6 ≈ x . . . . . . . . . . divide by 11
Aidan traveled about 523.6 km by train.
A rectangular prism is filled with 356 cubes with an edge length of 1/4 what is the volume of this prism
Answer: volume = 5.5625 cubic units.
Step-by-step explanation:
A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.
We know that for a cube with side length L, the volume is:
V = L^3
And we know that these small cubes have an edge length of 1/4 units.
Then the volume of each small cube is:
V = (1/4)^3 cubic units
V = (1/64) cubic units
And the volume of the prism will be 356 times that, then the volume of the prism is:
volume = 356*(1/64) cubic units
volume = 5.5625 cubic units.

You want to surround the perimeter of a garden with 35 stones. You need to place a certain number of large and small stones and every large stone you want to use 4 small stones. Choose the correct equation to find the number of stones for each size
Answer:
The answer is "x + 4x = 35; 7 large stones and 28 small stones"
Step-by-step explanation:
Please find the complete question in the attached file.
Let
[tex]x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35[/tex]
Users want to use four small stones for each big stone:
[tex]Y = 4x[/tex]
solving the equations system:
[tex]x + y = 35\\\\y = 4x[/tex]
we find:
[tex]x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\[/tex]

I am multiple of 20 i have 3 digits my hundreds digit and tens digit add to make 9 half of me is less than 100 what am i
Answer:
180
Step-by-step explanation:
Given :
the number has three digits
it is multiple of 20
hundreds digit and tens digit add to make 9
half of it is less than 100.
I suppose 180 can correctly fit into all above criterions
It is 3 digit number. 1+8 =9, 180/2 =90 which is less than 100.

Choose all answers that apply:
A 8 = 6
B 8 =8
C 8= 10
Answer:
the possible answer would be A, 6.
Step-by-step explanation:
6/2 is equal to 3 wholes. 7 minus 3 is 4. the sign > is used to indicate that the left number is greater than the right number, which is 3. 4 > 3 would be shown. this means that 6, or A, is the answer! :)

The large and medium shapes are scale drawings of the smallest shape the scale factor from the large shape to the media shape is 65% the scale factor from the medium shape to the small shape is 40% what is the scale factor from the large shape to the small shape
Answer:
25
Step-by-step explanation:
Add 65+40 which is going to give you 105 then once you get 105 subtract 65-40 which is going to give you 25 the 105 is the total so the whole answer is 25
