You've found the prime factorization when all of your factors are prime. They can't be divided into any smaller factors.

You know because all the factors are prime, none of them are one, and they multiply to make said number.

Hope this helps :)<span />

What is the area of a rectangle of 5/9 m in length and 7/8 m in width

Andru [333]

Answer:

35/72 $m^2$

Step-by-step explanation:

Rectangle Formula: $l*w=Area$

Switch the variables with the numbers given:

$\frac{5}{9} *\frac{7}{8} =Area$

Multiply the top and bottom:

5*7 = 35

9*8 = 72

35/72 = Area

A truck traveling 45 miles per hour and a train traveling 60 miles per hour cover the same distance. The truck travels 2 hours l

anygoal [31]

Answer:

6-hours

D = C + T

Step-by-step explanation:

The following equations represent the total distance travelled by each vehicle, the truck (C) and the Train (T) where x is the amount of time travelling in hours...

C = 45x

T = 60x

Since the truck traveled 2 hours longer than the train we can add this value to the variable x in the truck's distance equation and then make both equations equal one another to calculate the number of hours before they cover the same distance...

45(x+2) = 60x ... distribute 45 evenly

45x + 90 = 60x ... subtract 45x from both sides

90 = 15x ... divide both sides by 15

6 = x

Finally, we can see that both vehicles would have traveled the same distance at the 6-hour mark. Now to calculate the total distance traveled (D) we can use the following equation...

D = C + T

In △ABC, m∠B = 45, a = 24 ft, and c = 30 ft. Find b. Round your answer to the nearest tenth.

Zarrin [17]

To get the value of b we use the cosine rule:
c²=a²+b²-2ab Cos C
in our situation the formula will be:
b²=a²+c²-2ac Cos B
thus plugging our values we shall have:
b²=24²+30²-2×24×30×Cos45
b²=457.76624
b=21.3955~21.4 ft
Answer: 21.4 ft

David measured the height of a window frame as 5.61 feet, but the actual height was 6 feet. What is the percentage of error in D

Nataly [62]

<h2>Percentage of error in David's measurement is 6.5 %</h2>

Step-by-step explanation:

Measured height = 5.61 feet

Original height = 6 feet

Error in measurement = Original height - Measured height

Error in measurement = 6 - 5.61

Error in measurement = 0.39 feet

$\texttt{Percentage of error in David's measurement = }\frac{\texttt{Error in measurement}}{\texttt{Original height}}\times 100\\\\\texttt{Percentage of error in David's measurement = }\frac{0.39}{6}\times 100\\\\\texttt{Percentage of error in David's measurement = }6.5\%$

Percentage of error in David's measurement is 6.5 %
