Answer:

15 ml

Step-by-step explanation:

Find the volume of the tank which is 1.8m*0.6m*0.5m=0.54m^3

For every 0.18m^3,5ml of treatment is added,what of 0.54m^3

(0.54m^3*5ml)/(0 18m^3)=15ml

Eva is making a pattern using these shapes can you arrange Evas shapes to make a symmetrical pattern
ratelena [41]

Answer:

pyramid, cone, sphere, cube

Step-by-step explanation:

A symmetrical pattern is one that is arranged in such a way that there is a progressive repetition of a pattern. Each pattern formed is the same with respect to each other.

Eva could form series symmetrical patterns with the shapes he has, which depends on the arrangement of the shapes to form desired pattern.

One simple pattern to be formed is;

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube.

Thus, this would generate four symmetrical continuous patterns.

pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube.

1.What are the coordinates of the vertices of ABC? Use the coordinates to find the lengths of AC and AB .
Andrew [12]

Answer/Step-by-step explanation:

1.

✔️Coordinates of vertices ABC:

A(2, 2)

B(6, 2)

C(2, -1)

✔️AC = |2 - (-1)| = 3 units

AB = |2 - 6| = 4 units

2. Distance formula => d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Distance between B(6, 2) and C(2, -1):

BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Where,

B(6, 2) = (x_1, y_1)

C(2, -1) = (x_2, y_2)

BC = \sqrt{(2 - 6)^2 + (-1 - 2)^2}

BC = \sqrt{(-4)^2 + (-3)^2}

BC = \sqrt{16 + 9} = \sqrt{25}

BC = 5 units

The following pairs of angle measures are the measures of 2 angles of 2 triangles. Which pair of triangles would NOT be simular
posledela
So to solve this question, just add up all the three angles (ignoring the second pair of the same angle)

So for example:

A) \sf{41+20+119=180}

So that equals to 180, and so it is not the answer choice since the triangles would have similar angles.

B) \sf{82+70+28= 180}
Also not the correct answer choice.

C) \sf{58+30+92= 180}
Also not the correct answer choice.

D) \sf{35+82+73=190}
So this triangle will not have similar angles, thus your correct answer! :)

\boxed{\sf{D ~which~is~35~and~82;~82~and~73~is~your~answer!}}
