Ann reads 10 pages of her book every

Semenov [28]

Answer: Ann read 34 pages that day

Step-by-step explanation:

Ann reads 10 pages of her book everyday

And with every free minute she has she can read 2 pages

With 12 free minutes that day we do the following:

Multiply 12 by 2 to get the number of pages she reads in that free time which equals 24.

Then we add that 24 to the 10 pages she will read regardless.

Which leaves us with 34 pages.

Hope This Helps! :)

Vince has a rectangular rug in his room with an area of 10 ft the length of the rug is 18 inches longer than the width what coul

aev [14]

The length of the rug is 4 ft.

The width of the rug is 2.5 ft.

Explanation:

The area of the rug is 10 ft.

The length of the rug be l.

Let us convert the inches to feet.

Thus, $18 inches = 1.5 ft$

Thus, the length of the rug is $l=1.5+w$

Let the width of the rug be w.

Substituting these values in the formula of area of the rectangle, we get,

$A=length\times width$

$10=(1.5+w)(w)\\10=1.5w+w^2\\w^2+1.5w-10=0$

Solving the expression using the quadratic formula,

$w=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Substituting the values, we have,

$$w=\frac{-15 \pm \sqrt{15^{2}-4 \cdot 10(-100)}}{2 \cdot 10}\\$

$w=\frac{-15 \pm \sqrt{4225}}{20}$

$w=\frac{-15 \pm 65}{2 0}$

Thus,

$w=\frac{-15 + 65}{2 0}\\w=\frac{50}{20} \\w=2.5$ and $w=\frac{-15 - 65}{2 0}\\w=\frac{-80}{20} \\w=-4$

Since, the value of w cannot be negative, the value of w is 2.5ft

Thus, the width of the rug is 2.5ft

Substituting $w=2.5$ in $l=1.5+w$ , we get,

$l=1.5+2.5\\l=4$

Thus, the length of the rug is 4 ft.

Humans have a normal body temperature of 98.6 F A temperature, x, that differs from normal by at least 2°F is considered unhealt

Romashka-Z-Leto [24]

Answer: 98.6 - x ≥ 2 or x - 98.6 ≥ 2

Step-by-step explanation:

Since, the normal temperature = 98.6° F

Also, the temperature that differs from normal by at least 2°F is considered unhealthy.

If the temperature is x degree F,

Then, we have two conditions,

Condition 1 : x > 98.6,

The difference between 98.6 and x = x - 98.6

Then the inequality be,

x - 98.6 ≥ 2

Condition 2 : x < 98.6

The difference between 98.6 and x = 98.6 - x

Then the inequality be,

98.6 - x ≥ 2

Adidea Corp. estimates that $5,670 of its accounts receivables are uncollectible. How will the company record the transaction?

sergiy2304 [10]

Answer:

The transaction will be recorded by the company as :

DR : Non-collectibles $5670

CR : Accounts receivable $5670

Step-by-step explanation:

Amount of money estimated = $5670

The amount which is non-collectible is recorded as a DEBIT transaction by the company because the amount in the non-collectible account can't be received by the company.

But, the amount in the receivables is the amount which is available for receiving and can be received by the company. So, receivable transaction is marked as CREDIT by the company.

Thus, the transaction will be recorded by the company as :

DR : Non-collectibles $5670

CR : Accounts receivable $5670
