George is putting trim around his rectangular deck, including the gate. He will need 46 feet of trim to do the entire deck. If the deck is 15 feet long, how wide is the deck?
A.
6 feet
B.
16 feet
C.
8 feet
D.
23 feet
Answer:
C: 8 feet
Step-by-step explanation:
You have to find the parameter.
To do that you add all the side lengths together.
15+15=30 now you have to subtract 30 from 46 to find how much room is left.
46-30=16 now divide your answer by 2 to get the 2 remaining sides of the deck.
16/2=8 so the answer is 8!

C

Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi.
units^3
3
Answer: pie r^2 h
where pie is 3.143... , or 14
r- radius
h- height
Step-by-step explanation:
suppose let the cylinder height =3 and radius =4
volume of cylinder =pie*r^2*H
= 3.143*4^2*3
=150.864 m^3

What type of triangle is this triangle?
acute scalene
obtuse isosceles
obtuse scalene
acute isosceles
Answer:
Obtuse scalene
Step-by-step explanation:
Answer:
obtuse scalene
Step-by-step explanation:
Scalene means that none of the sides are equal.
Isosceles means that two of the sides are equal.
Obtuse means an angle in the triangle is larger than 90 degrees.
Acute means all angles in the triangle are smaller than 90 degrees.
None of the sides are equal so this triangle has to be scalene and the angle in the bottom right is larger than 90 degrees so this triangle is obtuse.
Hope this helps! :)

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.
Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?
350 m/s
355 m/s
360 m/s
365 m/s
Answer:360 m/s
Step-by-step explanation:
The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
As we can see in the graph:
When the air temperature is 10°C the speed of sound is around 337m/s
When the air temperature is 20°C the speed of sound is around 344m/s
When the air temperature is 30°C the speed of sound is around 348m/s
When the air temperature is 40°C the speed of sound is around 355m/s
From the above observation, the air temperature increases the speed of the sound increases.
So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.
Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.
