Answer:

The first fraction is between 27 and 28, closer to 28. The second fraction is between 3 and 4, closer to 4. Compatible numbers in division are numbers that can be divided mentally. 28 divided by 4 is 7. The quotient will be around 7.

Step-by-step explanation:

Answer:

The fraction 27 and two-thirds are between 27 and 28, closer to 28.

The fraction 3 and StartFraction 9 over 10 EndFraction is between 3 and 4, closer to 4.

Compatible numbers are easily divided.

By changing the numbers to 28 and 4, you can use the division 28 ÷ 4 = 7.

Tanzania [10]
For the answer to the question above, when you carry your jewelry box or your phone 3 floors down 
and 2 miles to the left, the angles and side lengths don't change, 
and it still looks exactly the same as it did before you picked it up 
and moved it.

Translation can't change angles or lengths.  And if those don't 
change, then the later shape is congruent to the earlier shape.

The graph of the function f(x) = (x + 2)(x + 6) is shown below.
iren [92.7K]

Answer:

Step-by-step explanation:

f(x) = (x + 2)(x +6)

1) The function is positive for all real values of x where   x > –4 :

COUNTER-EXAMPLE : x =  - 3   you have -3>-4 but   (-3+2)(-3+6) = -1 ×3 =-3 no positive .

2) The function is positive for all real values of x where

x < –6 or x > –3.

COUNTER-EXAMPLE : x =  - 2.5   you have -2.5>-3 but   (-2.5+2)(-2.5+6) = -0.5 ×3.5 =-1.75 no positive .

same method for the statement : "The function is negative for all real values of x where

x < –2."

conclusion : statement about the function is true: "The function is negative for all real values of x where

–6 < x < –2."

Natalka [10]
To find the awnser, the equation would be: the volume of the can - the volume left

to find the value,we can use 3.14 for 丌

The volume of the can would be the base area (丌r^2)times it's height,which in this case the volume is:

3.14(5)^2×12
=3.14×25×12
=942 cm³

The volume left:
3.14(5)^2×4
=314cm³

Thus,Mishka used:
942-314
=628 cm³

The answer is 628cm³

Hope it helps!

The orbit of the planet Venus is nearly circular. An astronomer develops a model for the orbit in which the sun has coordinates
klio [65]
Since the Venus orbits round the sun, the sun is the center of the circular path of the revolution of the planet, Venus.

Thus, the distance of the planet, Venus fron the sun is given by the distance between the points (0, 0) and (41, 53).

Recall that the distance between two points (x_1, y_1) and (x_2, y_2) is given by d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Thus, the distance between the points (0, 0) and (41, 53) is given by:

d= \sqrt{(41-0)^2+(53-0)^2}  \\  \\ = \sqrt{41^2+53^2} = \sqrt{1,681+2,809}  \\  \\ = \sqrt{4,490} =67 \ units

Given that each unit of the plane represents 1 million miles, therefore, the distance from the sun to the Venus is 67 million miles.
