Let's firstly convert the mixed fractions to "improper", and then divide,

$\bf \stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}}
\\\\\\
\cfrac{7}{4}\div -21\implies \cfrac{7}{4}\div \cfrac{-21}{1}\implies \cfrac{7}{4}\cdot \cfrac{1}{-21}\implies \cfrac{7}{-84}\implies \stackrel{simplified}{-\cfrac{1}{12}}$

Hello!

To do this you will simply convert 3/4 to 0.75 and divide.

1.75/-21=1/12.

Our final answer is $\frac{1}{12}$ .

I hope this helps!

Please help problems below!!

Answer:

9. B 10. C 11. A 12. C

Step-by-step explanation:

Greater rate of change simply means slope! Which ever of the functions has the greatest slope (positive or negative)

a. The graph shows the line going up by 4, and across by 3, or, a slope of 4/3

b. the table is increasing by 10, so, 10/1

c. -6 = -6/1, out of all of these, we divide by the denominators and determine which number is the greatest, ignoring whether or not the value is positive or negative

a. 4/3 = 1.333333

b. 10/1 = 10

c. -6/1 = -6 (remember, ignore the sign)

In this case, B is the greatest number, therefore, it has the greatest rate of change

10.

a. -3 / 3 = -1 (ignore the negative!)

b. 2/1 = 2

c. 4/1 = 4

In this case, C, is the greatest number, meaning its rate of change is highest

11.

a. -1/3 = -0.333333 (ignore the yk what!)

b. 0.25/1 = 0.25

c. -1/5 = -0.20 (you already know)

In this case, a, is the greatest number, meaning, its rate of change is the highest

12.

a. 0/1 = 0

b. 0.5/1 = 0.5

c. 2/1 = 2

In this case, c, is the greatest number, meaning, its rate of change is the highest.

Hope this helps!! <3

Write down a fraction whose value lies between 3 and 4; whose denominator is a multiple of 5; whose numerator is a multiple of 1

slamgirl [31]

Answer:

33/10 and 55/15

Step-by-step explanation:

Possible denominators that are multiples of 5 less than 17 are 5, 10, 15.

Corresponding numerator ranges are [15, 20], [30, 40], and [45, 60]. In only two of these ranges are there any multiples of 11.

33 in [30, 40]

55 in [45, 60]

So, there are only two possible fractions meeting your requirement:

33/10 and 55/15

You make $25000 a year, and you get a 10% raise. Your new salary is $____ The next year you get a 10% cut. Your new salary is $_

gtnhenbr [62]

Firstly, we have to find out what 10% of $25000 is. To do this, multiply $25000 by 0.1 (10% in decimal form): $\$25000 \times 0.1=\$2500$ . $2500 is the 10% raise.

Next, to find your first new salary, add $25000 and $2500 together: $\$25000+\$2500=\$27500$ . $27500 is your new salary after the 10% raise.

Next, we need to find 10% of $27500. It's a similar process as to finding 10% of $25000. $\$27500 \times 0.1=\$2750$ . $2750 is your 10% cut.

Next, since this is a cut, subtract $2750 from $27500. $\$27500-\$2750=\$24750$ . $24750 is your new salary after the 10% cut.

Next, to find the percentage change, firstly divide $24750 by $25000. $\frac{\$24750}{\$25000}=0.99\ \textsf{or}\ 99\%$ . Now this shows that your current salary is 99% of what you used to make. It is not how much less you make. To find how much less it is, subtract 99% from 100%: $100\%-99\%=1\%$ . Your current salary is 1% less than what you used to make.
