Carol bought a bamboo plant that was 62/4 feet high. when she got it home she cut 44/6 feet off of it . how tall was the plant a

Evgesh-ka [11]

Simplifying the values

$$6 \frac{2}{4} =\frac{26}{4}$ and $$4 \frac{4}{6} = \frac{28}{6}$ , we get

$$\frac{11}{6}$ tall was the plant after she cut it down.

<h3>What is fraction rule?</h3>

Let, the values be a, b, and c, then we get

$\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}$

Carol bought a bamboo plant that was $$6 \frac{2}{4}$ feet high. when she got it home she cut $$4 \frac{4}{6}$ feet off of it.

$$6 \frac{2}{4} =\frac{26}{4}$ and $$4 \frac{4}{6} = \frac{28}{6}$

The common denominator exists 24,

$$\frac{26}{4}-\frac{28}{6}$

the term $\frac{26}{4}=\frac{13}{2}$

$$=\frac{13}{2}-\frac{28}{6}$

Canceling the term $\frac{28}{6}= \frac{14}{3}$

$$=\frac{13}{2}-\frac{14}{3}$

Least Common Multiplier of 2, 3 = 6

Adjust Fractions based on the LCM

$$=\frac{39}{6}-\frac{28}{6}$

By applying the fraction rule we get

$\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}$

$$=\frac{39-28}{6}$

Subtract the numbers, and we get

39 - 28 = 11

$$=\frac{11}{6}$

$$\frac{11}{6}$ tall was the plant after she cut it down

The correct answer is $$\frac{11}{6}.$

In a company, 37% of 1500 employees are females.work out the number of males in the company.

a_sh-v [17]

Formula:

$y = p\% \times x$
$p = 37\% \div 100 = 0.37$
$y = 0.37 \times 1500 = 555$
so there are 555 woman working.
$1500 - 555 = 945$
there are 945 men working

A motorboat can maintain a constant speed of 26 miles per hour relative to the water. The boat makes a trip upstream to a certai

maks197457 [2]

Answer:

7 mph

Step-by-step explanation:

A boat whose speed in still water is 26 mph makes a trip upstream in 33 minutes and returns in 19 minutes. You want to know the speed of the current.

<h3>Setup</h3>

The travel time is inversely proportional to the speed, so we can write the proportion (using c for the current speed in mph) ...

time upstream / time downstream = speed downstream / speed upstream

33/19 = (26 +c)/(26 -c)

<h3>Solution</h3>

Multiplying by 19(26 -c) gives ...

33(26 -c) = 19(26 +c)

(33 -19)(26) = (33 +19)c . . . . add 33c -19(26)

14(26)/(52) = c = 7

The speed of the current is 7 miles per hour.
