IRINA_888 [86]

Change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.

<h3><u>Solution:</u></h3>

Given that

A clogged bathtub drains at a constant rate.

The amount of water in the bathtub changes by –3.75 gallons in one hour.

Need to determine change in the amount of water in the bathtub after 13 hour.

Change in amount of water in bathtub in one hour = -3.75 gallons

As given that clogged bathtub drains at a constant rate, so

Change in amount of water in bathtub in 13 hours = 13 x Change in amount of water in bathtub in 1 hours

=> Change in amount of water in bathtub in 13 hours = 13 x ( -3.75 ) = -48.75 gallons

Hence change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.

Mrs. Lin is sewing costumes for her grandchildren. She is making three lion costumes, one zebra costume, and two bear costumes.

stepladder [879]

Answer:

$12\frac{1}{8}\ yd$

Step-by-step explanation:

we know that

The total fabric that Mrs. Lin needs is equal to

$3(1\frac{2}{3})+2\frac{5}{8}+2(2\frac{1}{4})$

Convert mixed number to an improper fraction

$1\frac{2}{3}=1+\frac{2}{3}=\frac{5}{3}$

$2\frac{5}{8}=2+\frac{5}{8}=\frac{21}{8}$

$2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}$

substitute

$3(\frac{5}{3})+\frac{21}{8}+2(\frac{9}{4})$

$5+\frac{21}{8}+\frac{9}{2}$

$\frac{40+21+36}{8}=\frac{97}{8}\ yd$

Convert to mixed number

$\frac{97}{8}\ yd= \frac{96}{8}+\frac{1}{8}=12\frac{1}{8}\ yd$

Sorry it doesn’t go bigger but please help.

This is an arithmetic sequence (graph is a line), so function:

a(n) = First term + (n-1) * Common Difference

Here First term = 42 and Common difference = 34 - 36 = -2 so

$a(n)=42+(n-1)\cdot(-2)\\\\\boxed{a(n)=42-(n-1)\cdot2}$

Answer B.
