What you can do is count all the shapes the put the number of blue with that into a fraction. Lets say that there are 24 shapes and 15 are blue the fraction would be 15/25

Hope this helped. If you post a pic I can help you more.

A 2000-gallon metal tank to store hazardous materials was bought 15 years ago at cost of $100,000. What will a 5,000-gallon tank
harkovskaia [24]

Answer:

The value  is P_o = \$ 561958.9

Step-by-step explanation:

From the question we are told that

  The capacity of the metal  tank is  C =  2000 \  gallon

   The duration usage is  t = 15\ years \ ago

   The cost of 2000-gallon tank 15 years ago is P =  \$100,000

    The capacity of the second tank considered is C_1 = 5,000  

    The power sizing exponent is e = 0.57

     The initial construction cost index is  u_1 = 180

      The new construction after 15 years cost index is  u_2 =600

Equation for the power sizing exponent is mathematically represented as

      \frac{P_n}{P} = [\frac{C_1}{C} ]^{e}

=> Here P_n is the cost of 5,000-gallon tank as at 15 years ago  

So

     P_n  =  [\frac{5000}{2000} ] ^{0.57} * 100000

      P_n  =  \$168587.7

Equation for the cost index exponent is mathematically represented as

      \frac{P_o}{P_n}  =  \frac{u_2}{u_1}

HereP_o is the cost of 5,000-gallon tank today

So

       \frac{P_o}{168587.7}  =  \frac{600}{180}

=>    P_o = \frac{600}{180} * 168587.7

=>      P_o = \$ 561958.9

1. x2 + 12x + 27 = 0<br> what’s the answer ?
Ostrovityanka [42]

Answer:

x^{2} + 3x +9x +27 = 0

x(x+3)+9(x+3)=0

(x+3)(x+9)=0

x=-3, x=-9

Step-by-step explanation:

a=1 b=12 c=27

sum=12

factor=27x 1

          3x9

also 3+9=12

Which sentence about the diagram is true?
LUCKY_DIMON [66]
Answer is choice C: If a line is drawn through point A and point X, then it will bisect line segment BC.

This line is the third missing median of the triangle. A median goes from one vertex to the midpoint of the opposite side. The midpoint cuts the segment in half. For example, median CD cuts segment AB in half (AD = DB). All three medians of a triangle meet at the same point: the centroid
