Answer:

He can feed 200 plants

Step-by-step explanation:

First lets convert 25g to kg

25g = 0.025kg

Using proportion,

Let x be the number of plant he can feed

0.025kg = 1 plant

5kg        = x

cross-multiply

0.025×x=5×1

0.025x= 5

Divide both-side of the equation by 0.025

0.025x/0.025= 5/0.025

At the left-hand side of the equation 0.025 will cancel-out 0.025 leaving us with just x while at the right-hand side of the equation 5 will be divioded by 0.025

x=200 plants

Therefore, he can feed 200 plants

The amount of bacteria in a fish tank was 830. After 5 hours, the amount of bacteria is 3202.
alina1380 [7]

Answer: 37.92

Step-by-step explanation: We know that 3202 / 5 = 640.4.

We subtract that by 830 to get (830 - 640.4  =) 189.6. Then we do / by five again to get 37.92. That is the answer.

CONGRUENT TRIANGLES WORKSHEET. NEED ASAP DUE TODAY
WINSTONCH [101]

Answer:

Congurent triangles are those which map onto them selves perfectly. This means they share the same angle measurements and side lengths. Therefor we can figure out the side lengths by using the information in both triangles.

AD=5x+11

in the congurent triangle, the corresponding side equals:

CM=7x-3

CM and AD are congurent triangles meaning their sidelengths equal the same. Therefore...

5x+11=7x-3

Now we just solve to find the length of AD and CM (equal lengths)

5x+11=7x-3

11=2x-3

14=2x

7=x

x=7

If x=7 then we can plug it in for AD to find the side length.

5(7)+11=46

Notice that CM equals the same 7(7)-3=46

This is because... they are congruent triangles.

These rules also apply for all angle measurements of congruent triangles:

The m<v is equal to the meaasure of E (corresponding angles in congrurent triangles are equal)

We already astablished what x was (x=7) meaning if we find the measure of E then we have the measure of V sicne they are corresponding angles in a congrurent triangle.

(6x7+1)=43°

therefore the m<v is equal to 43°

46 and 43° is your answer
