Answer:

y is 16

Step-by-step explanation:

If y varies directly as x, and y is 48 when x is 6, find the value of y when x is 2

When y varies directly as x then $y=kx$

where k is the constant of proportionality

y is 48 when x is 6, plug in the value and find out k

$y=kx$

$48=k(6)$

Divide both sides by 6

$k=8$

The equation y=kx becomes

$y=8x$

find the value of y when x is 2

$y=8(2)= 16$

So the value of y is 16

It is y= 8x As given, y varies directly as x and y is 48 when x is 6. So from the equation we can justify it. When x=6 y= 8(6) = 48 Now, if x=2 y = 8(2) y = 16

John had 2/3 of his homework completed Sarah had 5/10 Alex 7/ 8 Michelle 1/2 who completed the most of the homework assignment

spayn [35]

Alex did the most amount of the homework assignment because if you turn them all into a fraction with a common denominator, Alex would have the most.

The fractions will be 80/120, 60/120, 60/120, and 105/120 which is Alex.

erika estimates that she is 200 to 300 miles away from her destination. if her car travels 25 miles per gallon of gas and each g

DedPeter [7]

Answer:

32$ < x < 48$

Step-by-step explanation:

Erika estimates that her destination is between 200 and 300 miles away.

When we divide 200 with 25 miles we get 200/25 = 8 gallons

When we divide 300 with 25 miles we get 300/25 = 12 gallons

When we multiply 8 · 4 = 32$ we get amount of money for destination

200 miles x = 32$

When we multiply 12 · 4 = 48$ we get amount of money for destination

300 miles x = 32$

Since that the estimate destination is between 200 miles and 300 miles

then the best estimate for the amount of money is between

32$ < x < 48$

God with you!!!

What is the rational number equivalent to <br> __<br> 3.24?

guajiro [1.7K]

Answer:

$\frac{324}{100}$

Step-by-step explanation:

Think of a rational number as a fraction. The definition of a rational number is that it is the ratio of integers that, when divided, is either an integer, a decimal that terminates, or a decimal that repeats. 6/3 = 2 (6/3 is a rational number that divides to 2); 1/2 = .5 (1/2 is a rational number that divides to .5 which is a terminating decimal, meaning it ends); 1/3 = .33333333 (1/3 is a rational number that divides to .3333333 which is a repeating decimal). If we want to express 3.24 as a rational number, let's first put it into fraction form. The 4 in .24 is in the hundredths place, so as a fraction, .24 is 24/100. Check this on your calculator. Divide 24 by 100 and you get .24. So now what we have is $3\frac{24}{100}$

Now express that mixed fraction as an improper and you're done. 3 times 100 is 300; 300 + 24 = 324. Put that back over 100 and your rational number is 324/100. Check that on your calculator, as well, just to see that it's true.

Can two box plots have the same range and iqr

Salsk061 [2.6K]

Yes they can! Just because two plots have the same IQR and range, does not mean that the rest of the data has to be the exact same. For example, the median.
