Answer:
Let the width of the Rectangle be x inches
Then, length is (3x-5) inches
Perimeter of the Rectangle= 46 inches (given)
According to the above problem,
Equation :---- Perimeter=2(length+breadth)
<u>2{(3x-5)+x}=46</u>
2(4x-5)=46
(4x-5)=46/2=23
4x=(23+5)=28
x=28/4
<u>x=7</u>
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches
Answer:
13km
Step-by-step explanation:
Given data
Time= 8 days
Speed= 2 1/6 kilometers per day = 13/6 kilometers per day
Distance= ??
We know that
Speed= distance/time
therefore, Distance= speed*time
substitute
Distance= 13/6*8
Distance= 104/8
Distance= 13 km
Hence the crew did 13km
Answer:
Second option is the correct answer
Step-by-step explanation:
11.7
Formula: a^2 + b^2 = c^2
so substitute the numbers like this:
10^2 + 6^2 = c^2
both 10^2 and 6^2 are perfect squares:
10 × 10= 100 and 6 × 6= 36
100 + 36= c^2
add:
100 + 36 =
136 = c^2
now in order to get rid of the squared, you put it into a radical:
√136 = √c^2
note: whatever you do on one side, you do to the other
it's easier to use the calculator for this so put √136 and you're gonna get 11.66
since it's asking you to round it to the nearest tenth:
11.66 = 11.7
sorry if the explanation is kinda long ✋ i tried explaining it better in the end but i failed
