Point P is the orthocenter of the triangle.
We will use the Unitary method to solve this question
304/4=76
Therefore The train travels 76 miles per hour
76*7.5=570
Therefore the train travels 570 miles in 7.5 hours
<span>Answer:
17576=pir^2h
the amount of material M=2pir^2 +2pirh
M=2pir^2+2pir(17576/pir^2)
DrM= 4pir- 35152/r^2
DrM=0
0=4pir- 35152/r^2
r=(13*2^(2/3))/pi^(1/3)
17576=pi((13*2^(2/3))/pi^(1/3))^2)h
17576/(pi((13*2^(2/3))/pi^(1/3))^2))=h
r=14.0901
h=28.1801
M=3742.21 cm^2</span>
Answer:
8
Step-by-step explanation:
rows=x
each row=(x+5) tomatoes
she increased the number of rows by 3
and doubled the number of tomatoes in each row
3multiplied by x=3x
(2x+10) because she doubled them
3x+10÷2x
=8

Answer:
75 in^2
Step-by-step explanation:
The surface area is the sum of the areas
Area of the square:
A = s^2 = 5^2 =25
Area of one triangle
A = 1/2 bh = 1/2 (5)(5) = 25/2
There are 4 triangles
4* (26)/2 = 50
The sum is 25+50 = 75
