<u>Answer:</u>
- 31 mm² is the surface area.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Surface area of triangle = 3(1/2 x 4 x 4) + (1/2 x 4 x 3.5)
<u>Work:</u>
- 3(1/2 x 4 x 4) + (1/2 x 4 x 3.5) mm²
- => 3(2 x 4) + (2 x 3.5) mm²
- => 24 + 7 mm²
- => 31 mm²
Hence, <u>31 mm² is the surface area.</u>
Hoped this helped.
Hello :
the perimeter is P: P=2(W+L) W : the width L: <span>the length
2(8.5 +L</span>) = 39
17+2L = 39
2L =22
L= 11

Answer:
minimum of 13 chairs must be sold to reach a target of $6500
and a max of 20 chairs can be solved.
Step-by-step explanation:
Given that:
Price of chair = $150
Price of table = $400
Let the number of chairs be denoted by c and tables by t,
According to given condition:
t + c = 30 ----------- eq1
t(150) + c(400) = 6500 ------ eq2
Given that:
10 tables were sold so:
t = 10
Putting in eq1
c = 20 (max)
As the minimum target is $6500 so from eq2
10(150) + 400c = 6500
400c = 6500 - 1500
400c = 5000
c = 5000/400
c = 12.5
by rounding off
c = 13
So a minimum of 13 chairs must be sold to reach a target of $6500
i hope it will help you!
