Answer:
0.20? sorry if im wrong
Step-by-step explanation: <em>4+3+2+5</em>
The missing angle is 72 degrees because of vertex angles
B at most 3 times
2 3/4 - 1 1/4 = 1 1/2
1 1/2 ÷ 1/2 = 3
used 1/2 ounce 3 times
so I'd say the answer is b at most 3 times because he couldn't have used it more than 3 times
Answer:
A =62x^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is given by
A=2(wl+hl+hw)
Given a width of 2x and length of 3x and a height of 5x, substitute into the equation
A = 2(2x*3x+ 5x*3x+ 2x*5x)
A = 2(6x^2 + 15x^2 +10x^2)
Combine like terms
A = 2(31x^2)
A =62x^2
200 km....... 3,5 h
100 km........1,5 h
v1= 200/3,5=57,1
v2= 100/1,5= 66,6
vm=( 57.1+66,6)/2≈ 61,5 km/h
