2)Two rectangles were used to form the following figure. The dimensions of the interior angle are 8 and 13 inches. The dimensions of the exterior angle are 9 and 15 inches.What is the area of the shaded region in square inches?

Answers

Answer 1

Answer:

$\bf \textit{area of a parallelogram}\n\n A=bh~~ \begin{cases} b=base\n h=height\n[-0.5em] \hrulefill\n A=23.7\n b=y\n h=3 \end{cases}\implies 23.7=y3\implies \cfrac{23.7}{3}=y\implies 7.9=y$

Laura decides to walk to her job. She walks 1 1/2 miles in 3/5 hour. What is Laura’s walking rate? Laura Job is 4 1/2 Miles away if she starts walking tour job at 9:00 AM and schedule to start working at 11:00 AM will she arrive at her job on time

Answers

1.5 miles/ .6 hours = 2.5 miles per hour

her walking rate is 2.5 miles per hour

d= r * t

4.5 miles = 2.5 * t

divide each side by 3.5

4.5 /2.5 = t

1.8 = t

t = 1.8 hours

11 am - 9 am = 2 hours

She will make it to work on time because 1.8 hours < 2 hours

Lola is placing appetizers on plates She has 63 spring rolls and 84 cheese cubes She wants to include both appetizers on each plate Each plate must have the same number of spring rolls and cheese cubes. What is the greatest number of plates she can make using all of the appetizers ? How of each type of appetizer on each plate?

Answers

The largest common factor for 63 and 84 is 21. This tells you the greatest number of plates she can make using all of the appetisers as both numbers divide cleanly by 21, so there will be no left overs. The factors you multiply by are 3, for 63, and 4, for 84. Thus, you can have 3 spring rolls and 4 cheese cubes on each plate.

What is the lcm of 15 25 9 8.

Answers

Hi !

So,here we have to calculate the least common multiple of the numbers 15,25,9,8.

We have to break down every number as a prime number product:
15 = 3·525 = 5² 9 = 3² 8 = 2³

Then,we have to select common and uncommon numbers at the highest power so:

lcm : 2³·3²·5² = 8·9·25 = 1800

Final answer:

The LCM of 15, 25, 9, and 8 is 1800.

Explanation:

The least common multiple (LCM) of 15, 25, 9, and 8 can be found by prime factorizing each number.

15 = 3 * 5

25 = 5 * 5

9 = 3 * 3

8 = 2 * 2 * 2

To find the LCM, we need to take the highest power of each prime factor that appears in the factorization of any of the numbers. In this case, we need to take 2^3, 3^2, and 5^2.

So, the LCM of 15, 25, 9, and 8 is 2^3 * 3^2 * 5^2 = 8 * 9 * 25 = 1800.
