Answer:
13.8
Step-by-step explanation:
8+4+5=17
26×2=52
17+52=69
69×.20=13.8
Let, the numbers = x,y
x/y = 3/5
total ratio units = 3+5 = 8
value of 1 unit = 135/8 = 16.875
So, numbers would be 3(16.875) & 5(16.875) = 50.625 & 84.375
so, your answer is 50.625 & 84.375
B. Accuracy is if it's right or not. Precision is how many decimal places it goes out to. So it is precise but not accurate.
Solution
For this case we have the following
y+3 = x = 10
Then x= 10
So we can set up this equation:
y+3 = 10
y= 7
Then the answer is:
y=7
Answer:
The length of the diagonal support is 69 feet.
Step-by-step explanation:
Dimensions of the box: length = 6 feet
width = 5 feet
height = 8 feet
The diagonal support relates with the diagonal of the base and the height.
From the base of the box, let the length of its diagonal be represented by x. Applying Pythagoras theorem;
=
+ 
=
+ 
= 36 + 25
= 61
x = 
= 7.81
let the length of the diagonal support be represented by l. So that;
=
+ 
=
+ 
=
+ 64
l = 
= 61 + 8
= 69
Thus, the length of the diagonal support is 69 feet.
