Answer:

Explanation:
With unlike denominators find the Least Common Denominator (LCD)

LCD = 12
3x4=12

Multiplying numerators and denominators to get the LCD in all fraction denominators
=2×4/3×4 − 1×3/4×3

Then rewriting the equation with the equivalent fractions
=8/12 − 3/12

With like denominators we can operate on just the numerators
=(8−3)/12
=5/12

Answers

Answer:

[tex]\dfrac{3}{20}[/tex]

Step-by-step explanation:

We need to solve the given expression i.e.

[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}[/tex]

It can be calculated by simplifying such that,

25 = 5 × 5

16 = 8 × 2

14 = 7× 2

9 = 3 × 3

If we use all the values,

we get,

[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}=\dfrac{3}{20}[/tex]

So, the value of the above expression is equal to [tex]\dfrac{3}{20}[/tex].

Looking at the triangle we see the angles:

58, x

We also see a right angle, therefore you now have:

90, 58, 0

All three angles of a triangle should have a total of 180 degrees, so we add the known angles and subtract the total from 180.

90 + 58 = 148

180 - 148 = 32

Therefore, x = 32 or C

Step-by-step explanation:

Occupancy rate is defined as rooms sold divided by rooms available. If you
have 632 rooms available and sell 580 of them, what is your occupancy
rate? (Round to the nearest percent.)
a) 92%
b) 95%
c) 98%
d) 100%

Answers

Answer:

a.) 92% is the correct answer.

Step-by-step explanation:

To get the occupancy rate, you will need to divide the number of room sold to the number of rooms available and multiply that number by 100%, which is (580*100%)/632=91.77% ~ 92%

Students did push-ups for a fitness test. Their goal was 20 push-ups. For each student,
determine what percentage of the goal they achieved.
1. Elena did 16 push-ups.
2. Jada did 42 push-ups.
3. Lin did 13 push-ups.
4. Andre did 21 push-ups.

Answers

Answer:

1- 80%

2- 210%

3- 65%

4- 105%

Step-by-step explanation:

The percentage of the goal achieved by them:

1). 80%

2). 210%

3). 65%

4). 105%

Find the percentage

1). Goal of push-ups = 20

No. of push-ups done by Elena = 16

Percentage = 16/20 × 100

= 80%

2). Goal of push-ups = 20

No. of push-ups done by Jada = 42

Percentage = 42/20 × 100

= 210%

3). Goal of push-ups = 20

No. of push-ups done by Lin = 13

Percentage = 13/20 × 100

= 65%

4). Goal of push-ups = 20

No. of push-ups done by Andre = 21

Percentage = 21/20 × 100

= 105%

Thus, the above answers are correct.

A person invested \$150$150 in an account growing at a rate allowing the money to double every 13 years. How much money would be in the account after 22 years, to the nearest dollar?

Answers

Answer:

Amount after 22 year = $484.80 (Approx.)

Step-by-step explanation:

Given:

Amount deposit in bank = $150

Double in year = 13 year

Find:

Amount after 22 year

Computation:

A = P[1+r]ⁿ

Amount after 13 year = 2 x 150

Amount after 13 year = $300

300 = 150[1+r]¹³

2 = [1+r]¹³

Rate of interest = 5.477%

Amount after 22 year

A = P[1+r]ⁿ

Amount after 22 year = 150[1+5.477%]²²

Amount after 22 year = $484.80 (Approx.)
