You are told that sprinklers run for the same amount of time. lets refer to this time as T.
you are told that 4 sprinkles run one at a time for 50 minutes total. that means that T should be 50/4 = 12.5 minutes = 12 minutes and 30 seconds

picture is blurry but if they are similar find the scale between the known sides

 smaller triangle bottom looks like it says 8?

 the larger one is 16

8/16 = 0.5 so the smaller one is half the size of the larger one

 so half of 8 is 4 so y = 4

 since they are similar the angles would stay the same so angle B would be the same as s which is shown as 27 degrees.

8 1/2 x 4/11 please solve
irakobra [83]

Answer:

3 1/11

Step-by-step explanation:

8 1/2 x 4/11

Change to an improper fraction

(2*8+1)/2  * 4/11

17/2 * 4/11

68 /22

Divide the top and bottom by 2

34/11

Change back to a mixed number

11 goes into 34 3 times with 1 left over

3 1/11

Volume of composite figures
ollegr [7]

Given:

The diameter of cylinder is 6 in and the height of the cylinder is 8 in.

The dimensions of the cuboid are 15 in by 9 in by 9 in.

To find:

The volume of the composite figure.

Solution:

Volume of a cuboid is:

V_1=length\times breadth\times height

V_1=15\times 9\times 9

V_1=1215

So, the volume of the cuboid is 1215 cubic inches.

The diameter of cylinder is 6 in. So, the radius of the cylinder is:

\dfrac{6}{2}=3\text{ inches}

Volume of a cylinder is:

V_2=\pi r^2h

Where, r is the radius and h is the height.

Substituting r=3,h=8,\pi =3.14, we get

V_2=(3.14)(3)^2(8)

V_2=(3.14)(9)(8)

V_2=226.08

The volume of the cylinder is 226.08 cubic inches.

Now, the volume of the composite figure is:

V=V_1+V_2

V=1215+226.08

V=1441.08

Therefore, the volume of the composite figure is 1441.08 cubic inches.

What is the answer to -52 + 8|-1| + (-3)
dsp73

Answer:

the answer is is -47

Step-by-step explanation:

First take the 8|-1|

anything between the lines is turned positive. therefore it simplifies to just 8 * 1  

so, now we have -52 + 8 + (-3)

-52 + 8= -44

-44+(-3)=-47

hope this helps you! ^^

Help me!!!!!!!!!!!!!
RSB [31]
I will be using a practice problem with different endpoints, and I challenge you to solve this one using a similar strategy. The points I will be using is 
(1, 3) as T and (5, 4) as the midpoint

Alright - we know that the equation for the midpoint of a line segment is 
( \frac{ x_{1} + x_{2} }{2} , \frac{ y_{1} + y_{2} }{2} ) 
Next, we plug the x values in - since the midpoint's x value is 5 and one endpoint's x value is 1, we have 
\frac{1+x_2}{2} =5 .
Next, we multiply both sides by 2, resulting in 1+x₂=10. Lastly, we subtract 1 from both sides, meaning that x₂, or the x value of the other endpoint, is 9. For the y values, we use a similar process - 
\frac{3+y_2}{2} =4 .
since 3 is the y value of one endpoint and 4 is the y value of the midpoint. Multiplying both sides by 2, we get 3+y₂=8. Subtracting 3 from both sides, we get y₂=5 and our coordinates for the other endpoint to be (9, 5).

Good luck, and feel free to ask any questions as necessary!
