Answer:2.8 feet
Step-by-step explanation:
length(l)=?
breadth(b)= 1.9 feet
perimeter(p)=7.4 feet
we know,
p=2(l+b)
7.4=2(l+1.9)
7.4=2l+3.8
2l=7.4-3.8 (changing side and bringing 3.8 to 7.4 it gets -3.8)
l=3.6/2
l=2.8 feet
Hence,length is 2.8 feet
Answer:
3.44 x 10^6
Step-by-step explanation:
41 x 8.4 = 344.4
344.4 x 10^4 = 3.44 x 10^4+2
Answer:
c
Step-by-step explanation:
Two sum of any two side lengths of a triangle will always be greater than the length of the remaining side
a doesn't work because 8+12=20 and 20 is not greater than 20
b doesn't work because 4+5=9 and 9<10
d doesn't work because 6+6=12 and 12 is not greater than 12
c is the only option where you can take any two sides, add them, and the sum will be greater than the remaining side.
For example, for c,
6+8=14, and 14>10
8+10=18, and 18>6
10+6=16, and 16>8
To find the total price, we use this equation:
42 + 0.039(42)
We can make it simpler:
1.039(42)
Multiply:
43.638
Because we're rounding
The total price is $43.64
WXY = XYW ( = 41 ) ⇒ XYW is a isosceles triangle
⇒ XW = YW
⇒ 54 = 6x + 6
⇒ 6( x + 1 ) = 54
⇒ x + 1 = 9
⇒ x = 8
ok done. Thank to me :>
