Total mass = 8 kg

Mass of tool 1 = 4 kg

Mass of tool 2 = 2 kg

So,

Total mass = Mass of tool 1 + Mass of tool 2 + Mass of tool 3

=> 8 kg = 4 kg + 2 kg + Mass of tool 3

=> 8 kg = 6 kg + Mass of tool 3

=> 8 kg - 6 kg = Mass of tool 3

=> 2 kg = Mass of tool 3

C. (x−9)^2+(y+2)^2=3
D. (x−2)^2+(y+9)^2=9

Answers

Answer:

(x-2)^2 + (y+9)^2 = 9

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x-2)^2 + (y--9)^2 = 3^2

(x-2)^2 + (y+9)^2 = 9

To paint a wooden cube, Pinocchio needs 4 grams of paint. When it is dry, he cut the cube into 8 smaller pieces of smaller size. How much paint additional paint does Pinocchio need to paint the unpainted surfaces of the smaller cubes

Answers

Answer:

9 grams of paint

Step-by-step explanation:

6×8=48

48÷4= 12

48-12=36

36÷4=9

first multiply 6 by 8 because a cube has six faces and you cut that cube eight times

second after you cut that you will have 48 faces and for every six faces there are 4 grams of paint so you divide 48 by 4 and you get 12 this means that 12 of the faces are painted

next you subtract 12 from 48 and you get 36 this means that 36 faces are not painted

lastly you divide 36 by 4 and you will get 9 grams of paint

A recipe requires 500 mL of milk. You will make the recipe once a month for the next 4 months. You do not use milk other than for cooking. Which container of milk should you buy? (1L=1000 mL) *

Answers

Answer:

2L

Step-by-step explanation:

Each recipe = 500 mL of milk

Number of times you make recipe per month = 1

Number of months you make recipe = 4

Total milk used for 4 months = 500 mL * 1 * 4

= 2000 mL

Recall,

1L = 1000 mL

Therefore,

2000 mL = 2L

You should buy 2L container of milk

Answers

Answer:

a=1/2,b=-1,c=-1 and d=1/2

Am I right please?

Answer:

a = 1/42; b = 1/7; c = 1/3; d = 1/2

Step-by-step explanation:

a = bcd

a + b = cd

a + b + c = d

a + b + c + d = 1​​

d + d = 1

2d = 1

d = 1/2

2a = bc

2a + 2b = c

2a + 2b + 2c = 1

bc + 2b = c

bc + 2b - c = 0

bc + 2b + 2c = 1

-3c = -1

c = 1/3

a + b = cd

a + b = 1/6

a = bcd

a = b(1/3)(1/2)

a = 1/6 b

1/6 b + b = 1/6

7/6 b = 1/6

b = 6/42

b = 1/7

a = 1/6 b

a = 1/6 * 1/7

a = 1/42
