Answer:16 ft 4 in


Step-by-step explanation:we want to find the height of the pole.

It's shadow is 2yards(6ft) long,

3 x the boy's shadow of 2ft long

Because the length of a shadow corresponds to the height of the object casting it, the poles height would be 3x the height of the boy.

His height is 5'6" (66")

66×3=196

196" = 16'4"

the sides of a triangle are 3 whole 1 by 6 cm 4 whole 2 by 3 cm and 5 whole 2 by 3 cm. Find the total length of the three sides
Lyrx [107]

Answer:

16\frac{2}{3}cm

Step-by-step explanation:

Given dimensions:

           3\frac{1}{6} cm by 4\frac{2}{3}cm  by 5\frac{2}{3} cm

The total length:

 it is the sum of all the sides;

         \frac{19}{6}  + \frac{14}{3}   + \frac{17}{3}  

LCM of the denominators = 6 ;

   \frac{38 + 28 + 34}{6}  = \frac{100}{6}

                 = \frac{50}{3}

                 = 16\frac{2}{3}cm

The local deli charges a fee for delivery. On monday, they delivered two dozen bagels to an office at a local cost of $8. On Tue
aev [14]

Answer:

  • 2b+f=8; 3b+f=11
  • b=3, f=2

Step-by-step explanation:

The problem statement defines the variables and gives the relations ...

  2b + f = 8 . . . . total cost on Monday

  3b + f = 11 . . . . total cost on Tuesday

__

Subtracting the first equation from the second, we get ...

  (3b +f) -(2b +f) = 11 -8

  b = 3 . . . . . simplify

Substituting this into the first equation, we can solve for f

  2·3 +f = 8

  f = 2 . . . . . . . subtract 6

Bagels cost $3 per dozen; the delivery fee is $2.

Work out the co ordinates of the midpoint of (-2,-1) and (-2,4)
s2008m [1.1K]

Answer:

(-2,\frac{3}{2})

Step-by-step explanation:

To find the midpoint, simply use the Midpoint Formula.

The Midpoint Formula states that for two points (x_1,y_1) and (x_2,y_2), the midpoint will be: (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} ).

So, here, (x_1,y_1) = (-2, -1) and (x_2,y_2) = (-2, 4). The midpoint is then: (\frac{-2+(-2)}{2} ,\frac{-1+4}{2} )=(\frac{-4}{2} ,\frac{3}{2} )=(-2,\frac{3}{2})

Thus, the answer is (-2,\frac{3}{2}).

Hope this helps!

Based on the graph below, how would you describe the curve?
Vinil7 [7]

The best description of the curve of the given graph is called; A: Many to One Function

<h3>How to interpret function graphs?</h3>

A function is a relation in which each element is mapped to a single element i.e. no element is mapped to two different elements.

The given graph passes the vertical line test and as such we can say it is a function.

Also, the graph of a linear function is a straight line but the graph we are given is not a straight line and as such it is not a linear function.

Lastly, the graph does not passes the horizontal line test because between the interval from -1 to 0, the same value y-output is obtained many times and hence it is not a one-to-one function but a many to one function.
