Answer:
0.3 hour or 18 minutes
Step-by-step explanation:
How long means, we are to calculate the time(t)
Hence,
Speed × time = Distance
For Neil , 11 × t
For Charlie = 9 × t
11t + 9t = 6
20t = 6
t = 6/20
t = 0.3 hour
Converting to minutes
1 hour = 60 minutes
0.3 hour = x
x = 0.3 × 60 minutes
x = 18 minutes
Therefore, it will take 0.3 hour or 18 minutes for these two to meet.

10. Tamara wants to find the height of a tree outside her home. Using her clinometer, she measures the slope angle from 8 feet away from the base of the tree and gets an angle of 40o . If Tamara's eye level is 5 feet above the ground, how tall is the tree (rounded to the nearest tenth of a foot)? Show your work.
Answer:
11.7 ft
Step-by-step explanation:
Remember the notation SOHCAHTOA
We would be using tan because we have been given the adjacent and we are to determine the opposite value
tan 40 = opposite / adjacent
0.8391 = opposite / 8
opposite = 0.8391 x 8
6.7
Tamera is 5 ft above ground = 6.7 + 5 = 11.7 foot
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Write the standard form of the equation of the circle with the graph shown to the right.
Answer:
(x+5)²+(y+5)² =4
Step-by-step explanation:
the standard equation is
(x-h)²+(y-k)²=r²
where (h, k) is the center in our case ( -5, -5) and r is the radius that in our case r=2, so substitute
(x+5)²+(y+5)²=2²
Answer:
[tex](x+5)^2+(y+5)^2=4[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius
1) Determine the center of the circle
On the graph, we can determine that the circle is centered at the point (-5,-5). Plug this into the equation:
[tex](x-(-5))^2+(y-(-5))^2=r^2\\(x+5)^2+(y+5)^2=r^2[/tex]
2) Determine the value of r²
In the graph, we can see that the radius of the circle is equal to 2 units. Therefore, the value of r² is 4. Plug this back into the equation:
[tex](x+5)^2+(y+5)^2=4[/tex]
I hope this helps!

Q1:
Med:
Q3:
Max:
Answer:
please check explanations
Step-by-step explanation:
Min stands for the minimum value
This is the smallest value
Looking at the numbers, the minimum value is 1
Q1 is the lower quartile
We have the formula as;
Q1 = (n + 1)/4
where n is the number of terms and that is 10
Q1 = (10 + 1)/4 = 11/4 = 2.75
This is approximately 3 and that means the the lower quartile is the third term and that is 6
Median is the middle value and that is;
(12 + 13)/2 = 25/2 = 12.5
Q3 is the third quartile and that is;
Q3 = 3(n + 1)/4 = 33/4 = 8.25
The third quartile is the 8th term and that is 14
Max is the highest number and that is 19

A cone and cylinder each have a height of 10 inches and a radius of 5 inches. If you filled the cone completely with water and poured it into the cylinder. How many times would it take until the cylinder is completely full with water?
Answer:
The times that would take until the cylinder is completely full with water by the cone are:
3 times.Step-by-step explanation:
To identify how many times we must fill a cone to fill completely a cylinder with the same height and radius, we must calculate the volume of the two containers and next divide the volume of the cylinder by the volume of the cone. To obtain the volume of the cylinder we can use the next formula:
Volume of a cylinder = [tex]\pi[/tex] * [tex]radius^{2}[/tex] * [tex]height[/tex]If we replace the values in the formula, we obtain:
Volume of a cylinder = [tex]\pi[/tex] *(5 inches)^2 * 10 inchesVolume of a cylinder = 785.4 inches^3 approximately.Now, we're gonna calculate the volume of the cone with the next formula:
Volume of a cone = [tex]\frac{\pi*radius^{2}*height }{3}[/tex]As you can see just with the formula, The volume of a cone is three times less than that of a cylinder (because we add the dividend 3 to it), but we're gonna replace and prove it:
Volume of a cone = [[tex]\pi[/tex] *(5 inches)^2 * 10 inches] / 3Volume of a cone = [785.4 inches^3] / 3Volume of a cone = 261.8 inches^3 approximately.And, if we divide the two volumes to obtain the times we need to fill the cone to fill completely the cylinder:
Times we need to fill the cone = 785.4 / 261.8Times we need to fill the cone = 3By this reason, you must fill completely a cone 3 times to fill completely a cylinder with the same radius and height.

In complete sentences, explain why correlation does not prove causation. Please have at least 3 complete sentences with proper punctuation, grammar, and capitalization.
Answer:
Correlation doesn't prove causation because just because two things correlate does not necessarily mean that one causes the other.It's easy to think that just because two things seem related, that one must be the cause of the other. But that can be a foolish and sometimes dangerous assumption

Help me with this question, please!
Answer:
3,432 m²
Step-by-step explanation:
The amount of aluminum in square meters needed to make the mailboxes = 1863(surface area of each mailbox)
Surface area of each mail box = ½(surface area of cylinder) + (Surface area of rectangular prism/box - area of the surface of the box that joins the half-cylinder)
✔️Surface area of ½-cylinder = ½[2πr(h + r)]
r = ½(0.4) = 0.2 m
h = 0.6 m
π = 3.14
Surface area of ½-cylinder = ½[2*3.14*0.2(0.6 + 0.2]
= 0.628(0.8)
Surface area of ½-cylinder = 0.5024 m²
✔️Surface area of the rectangular box/prism = 2(LW + LH + WH)
L = 0.6 m
W = 0.4 m
H = 0.55 m
Surface area = 2(0.6*0.4 + 0.6*0.55 + 0.4*0.55)
Surface area of rectangular box = 1.58 m²
✔️Area of the surface joining the half cylinder and the box = L*W = 0.6*0.4 = 0.24 m²
✅Surface area of 1 mailbox = (0.5024) + (1.58 - 0.24)
= 0.5024 + 1.34
= 1.8424
Amount of aluminum needed to make 1863 mailboxes = 1863 × 1.8424 = 3,432.3912
= 3,432 m²
2. A right triangle has a hypotenuse of 15 cm. What are possible lengths for the two legs of the triangle? Explain your reasoning.
Answer:
Two possible lengths for the legs A and B are:
B = 1cm
A = 14.97cm
Or:
B = 9cm
A = 12cm
Step-by-step explanation:
For a triangle rectangle, Pythagorean's theorem says that the sum of the squares of the cathetus is equal to the hypotenuse squared.
Then if the two legs of the triangle are A and B, and the hypotenuse is H, we have:
A^2 + B^2 = H^2
If we know that H = 15cm, then:
A^2 + B^2 = (15cm)^2
Now, let's isolate one of the legs:
A = √( (15cm)^2 - B^2)
Now we can just input different values of B there, and then solve the value for the other leg.
Then if we have:
B = 1cm
A = √( (15cm)^2 - (1cm)^2) = 14.97
Then we could have:
B = 1cm
A = 14.97cm
Now let's try with another value of B:
if B = 9cm, then:
A = √( (15cm)^2 - (9cm)^2) = 12 cm
Then we could have:
B = 9cm
A = 12cm
So we just found two possible lengths for the two legs of the triangle.

the correct answer is A
15 x 35
Answer:
A
Step-by-step explanation:
let width be w , then length l = w + 20
perimeter = 2w + 2l
= 2w + 2(w + 20) , so
2w + 2w + 40 = 100
4w + 40 = 100 ( subtract 40 from both sides )
4w = 60 ( divide both sides by 4 )
w = 15 and l = 15 + 20 = 35
Dimensions are 15 ft by 35 ft → A
Whenever w is an integer greater than 1, logw w^2/w^6=?
-4
-3
-1/3
1/3

Answer:
Option (1)
Step-by-step explanation:
Given expression is,
[tex]\text{log_w(\frac{w^2}{w^6})}[/tex][tex]\text{log}_w(\frac{w^2}{w^6} )[/tex]
Let the given expression is equal to y.
[tex]\text{log}_w(\frac{w^2}{w^6} )=y[/tex]
By applying logarithmic rule,
[tex](\frac{w^2}{w^6} )=w^y[/tex]
[tex]w^2\times w^{-6}=w^y[/tex]
[tex]w^{2-6}=w^y[/tex]
[tex]w^{-4}=w^y[/tex]
[tex]y=-4[/tex]
Therefore, value of the given expression [tex]\text{log}_w(\frac{w^2}{w^6} )=-4[/tex].
Option (1) will be the correct option.

Answer:
The probability that she would succeed is 1/2
Step-by-step explanation:
Firstly. we have to calculate the area of the board
That would be the area of the rectangle
This is the product of the base and the height which is 50 cm * 40 cm = 2,000 cm^2
The area of the triangle is the area of the base and the height divided by 2
we have this as;
1/2 * 50 * 40 = 1,000 cm^2
The probability would be the area of the triangle divided by the area of the board
This is because she is aiming at the triangle while having the whole board to work against
This is 1,000 cm^2/2000 cm^2 = 1/2
