For which equation is m = 12 the solution? a. 4m=40 b. m+20=42. c. 4m=48. d. m-4=9
Gelneren [198K]
To solve this question, we just need to insert 12 into the m position of each question and see if the equation holds true.

a. 4m = 40

4(12) = 40

48 = 40

48 obviously does not equal 40, so it is not choice A.

b. m + 20 = 42

12 + 20 = 42

32 = 42

Again, 32 isn't the same as 42, so not choice B either.

c. 4m = 48

4(12) = 48

48 = 48

It looks like this one is true, but let's solve D also just to make sure.

d. m - 4 = 9

12 - 4 = 9

8 = 9

This is false, since 8 does not equal 9.

Therefore, choice C (4m = 48) is the correct answer.
Hope that helped! =)

The Capacity of a 1 cm cube is 1 mL. How many 1 cm ice cubes do you need to melt to fill a 1.5 L jar.
Svetach [21]

1500 ice cubes need to fill 1.5 L jar

Solution:

1 cm = 1 ml

Capacity of ice cube = 1 cm

                                   = 1 ml

Capacity of jar = 1.5 L

1 L = 1000 ml

1.5 L = 1.5 × 1000

       = 1500 ml

Capacity of jar = 1500 ml

$\text{Number of ice cubes} =\frac{\text{Capacity of ice cube}}{\text{Capacity of jar}}

                                $=\frac{1500}{1}

                                = 1500

Therefore 1500 ice cubes need to fill 1.5 L jar.

How does the value of log Subscript 2 Baseline 100 compare with the value of Log Subscript 6 Baseline 20?.
attashe74 [19]

You can use the change of base formula to get

\log_2(100) = \frac{\log(100)}{\log(2)} \approx 6.643856

and also

\log_6(20) = \frac{\log(20)}{\log(6)} \approx 1.671950

In general, the change of base formula is

\log_b(x) = \frac{\log(x)}{\log(b)}
