If the area of a circle is 324 cm, find:
Its circumference in terms of pi

Answers

Answer 1

Answer:

20.3π cm

Step-by-step explanation:

Area of a circle = 324 square cm

    πr² = 324

   [tex]\frac{22}{7}*r^{2}= 324\\\\ r^{2} = \frac{324*7}{22}\\\\ r^{2}= 103.09\\\\ r =\sqrt{103.09}\\\\[/tex]

  r = 10.15 cm

Circumference = 2πr

                         = 2 *  π * 10.15

                         = 20.3π cm

Monthly gross pay =  $7650.68

Annual gross pay = $91808.16

Explanation:

To get the monthly gross pay, you double the semi-monthly gross pay. In other words, you multiply by 2.

Once you know how much you earn per month, you multiply that by 12 to get your annual pay.

The term "gross" in financial terms means the amount of money before taxes and other fees apply. The net pay is after taxes and other fees are deducted from your paycheck. This means the net pay is going to be smaller than the gross pay.

Aisha has $100 saved from her job. She wants to buy as many charms for her bracelet, at $4 each and earrings at $5 per set, as she can without spending all of her money. The inequality represents her spending, where x is the number of charms and y is the number of sets of earrings. 4x + 5y < 100 SAMSUNG Which ordered pair (x, y) represents a combination of charms and earrings Aisha can buy? A. (16,8) B. (15,8) C. (9, 13) D. (6, 15) E. , (5, 16)​

Answers

Answer:

The answer is D

Step-by-step explanation:

6 times 4 is 24

15 times 5 is 75

75 + 24 = 99

The rest of the answers go over 100

The ordered pair that represents a combination of charms and earrings Aisha can buy is (6,15).

What is inequality?

The relation between two unequal expressions is defined as inequality.

The given inequality is 4x+ 5y <100.

(A) Check the inequality for (16,8):

4(16) + 5(8) < 100

64 + 40 < 100

104 < 100

The inequality is false.

(B) Check the inequality for (15,8):

4(15) + 5(8) < 100

60 + 40 < 100

100 < 100

The inequality is false.

(C) Check the inequality for (9,13):

4(9) + 5(13) < 100

36 + 65 < 100

101 < 100

The inequality is false.

(D) Check the inequality for (6,15):

4(6) + 5(15) < 100

24 + 75 < 100

99 < 100

The inequality is true, hence, (6,15) represents a combination of charms and earrings Aisha can buy.

(E) Check the inequality for (5,16):

4(5) + 15(16) < 100

20 + 240 < 100

260 < 100

The inequality is false.

Hence, the ordered pair that represents a combination of charms and earrings Aisha can buy is (6,15).

Evaluating Mixed fractions and Adding like terms

Simplifying the Mixed Fractions:

to simplify these mixed fractions, we will multiply the whole number part with the fraction's denominator and add that to the numerator.

The number formed will be given the same denominator as of the fraction part in the number

After simplifying these mixed fraction, we get:

[tex]\frac{16}{5}x + \frac{97}{9}x - \frac{12}{5}x - \frac{98}{9}x[/tex]

Adding and Subtracting the like terms:

to simplify our calculations, we will pair the numbers with the same denominator

Upon substituting our given values in z-score formula we will get,



Now we will find the P(z>3) using formula:


Using normal distribution table we will get,


Let us convert our answer into percentage by multiplying 0.00135 by 100.

Therefore, approximately 0.135% of the adult male population is taller than the average basketball player and option A is the correct choice.

1. In a supermarket, each orange costs $3, and each apple costs $2. If you want to spend
exactly $45, write an equation in standard form modeling this situation. Let o represent
the number of oranges you buy, and a represent the number of apples you buy.

Answers

Answer:

3o  + 2a = $45 ( you can buy 9 oranges and 9 apples)

Step-by-step explanation:

First I divided 45 by 3 and I got 15 so now I know that 15 is the highest amount of oranges I can buy without going over $45. I also know that 15 cannot be an answer because I also have to buy apples.

Then I divided 45 by 2 and 22 was the highest whole number.

Now I would play trial and error BUT i know that the number for oranges have to be less that 15 and the number for apples has to be less than 22.

3 times 9 equals 27 (oranges)

45 - 27 = 18

2 times 9 equals 18 (apples)

3o+2a =$45 is the  equation in standard form modeling this situation.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that in a supermarket, each orange costs $3, and each apple costs $2.

Let o represents the number of oranges you buy

and a represent the number of apples you buy.

If you want to spend exactly $45

We have to find the equation to model this situation

3o+2a =$45

Hence, 3o+2a =$45 is the  equation in standard form modeling this situation.
