Find a common multiple between 30 and 42 that is bigger than them.
(Note: I'm not finding the LCM I just need a multiple bigger than them)

Answers

Answer 1

Answer:

210

Step-by-step explanation:

GCF(30,42) = 6

LCM(30,42) = ( 30 × 42) / 6

LCM(30,42) = 1260 / 6

LCM(30,42) = 210

Answer 2
1260

1260 is a multiple of 30 and 42.
30(42)=1260,
multiplying both of these numbers means that the result will always be a common multiple.

The ratio of balls to tennis balls is 4:7 is a correct statement; however, we need to check the other questions for reliablity.

For every 6 basketballs, there are 10 dodge balls is a wrong statement because the number of basketballs is 12 and the number of dodge balls is 18 not 20. So, this answer is wrong.

None of the above is wrong because the first answer is correct so we can cross out c.

Now we know that A is the correct answer!

It is A, the ratio of soccer balls to tennis balls is 4:7.

Soccer Balls : 8

Tennis balls: 14

8 divided by 2 is 4 and 14 divided by 2 is 7.

4:7

B is not right because

Basketball: 12

Dodgeball: 18

"For every 6 basketballs, there are 10 dodge balls."

12 divided by 2 is 6

If it was 10 dodge balls for every 6, dodge balls would be 20 because there are 2 6s in a 12.

And it can't be C, none of the above because A is correct.

So yea it's A.

A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.

Answers

Answer:

29.88 inches

Step-by-step explanation:

Equation of a line is given in the form  

Where

m is the slope [rate of change, here, rate of decrease]

c is the y-intercept [at 1920, the snowfall]

From the problem, we see that snowfall decreases by 0.24 inches per year, that will make the slope (m) to be -0.24

Also, at 1920, the initial measurement was 48.6 inches of snow, that is the y-intercept (b). Thus, we can write the equation of this line as:

y = mx + b

y = -0.24 x +48.6

To find annual snowfall, 78th year after 1920, we simply plug in 78 into "x" of the equation just found. So:

y = -0.24(78) + 48.6 = 29.88 inches

Answer:

29.88 inches

A cylinder has a volume of 1884cm^3. Find the volume of a cone with the same radius and height as the cylinder

Answers

Answer:

628

Step-by-step explanation:

The volume V of a cylinder whose radius is r and height is h is given as

V = πr²h

The volume of a cone v of a radius r and height h is also given as

v = 1/3 πr²h

As such , given that the cylinder has a volume of 1,884 cm ³, the volume of a cone with the same radius and height as the cylinder

= 1/3 * 1,884 cm ³

= 628 cm ³

i think it is 628 so tell me if i’m correct :)
