Answer:
C and E
Step-by-step explanation:
We are given that



A.

Hence, it is not in proportional relationship with (0.2,0.3)
B.(2.7,4.3)


Hence, it is not in proportional relationship with (0.2,0.3).
C.(3.2,4.8)


Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).
D.(3.5,5.3)

Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).
E.(5.2,7.8)

Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).
Answer:
(3t + 7) (t + 1)
Step-by-step explanation:
3t^2 + 10t + 7
(3t^2 + 3t) (7t+7)
3t (t+1) 7 (t+1)
(3t+7) (t+1)
Scarf area is 8 small fabric area
8 x 0.25 x 0.25 =0.5.
7 scarf area would be
7 x 0.5 = 3.5
new fabric (large ) area is
2 x 0.25 = 0.5
7 scarf area divide by new fabric area
3.5 divide by 0.5 = 7 large pieces
Answer: SECOND OPTION (52 cm³)
Step-by-step explanation:
The formula for calculate the volume of a cone is:

Where r is the radius and h is the height.
The formula for calculate the volume of a cylinder is:

Where r is the radius and h is the height.
As you can see, the difference between the the formulas is that r²hπ of the cone is divided by 3. Therefore, if you know the volume of the cylinder and you know that the cone has the same base and height as the cylinder, you have to divide the volume of the cylinder by 3 to obtain the volume of the cone.
Therefore, the result is:

Answer:
14/45
Step-by-step explanation:
So we have the fraction:

We can do this algebraically. Follow to following steps:
Let's let this number equal to n. Thus:

Since there is only 1 digit repeating, let's multiply everything by 10. So:

Now, subtract n from both sides:

On the left, substitute the number for n. On the right, combine like terms:

All of the 1s will cancel. So:

Subtract:

Divide both sides by 9:

Remove the decimal by multiplying both sides by 10:

Reduce:

And we're done!
