Answer:
the area = 28.27 or you can write the answer out as 28.2744 or also 28.27433
Step-by-step explanation:
start with what we know. the formula for solving this is A=pi R squared
so, area= pi (3.1416)
then, multiply that by the radius given, which is 3.
So, 9.4248 × 3 = 28.2744 square inches
or 28.27 sq.in.

2. [tex]\angle 4[/tex] and [tex]\angle 9[/tex] are Alternate Interior Angles
3. [tex]\angle 5[/tex] and [tex]\angle 16[/tex] are Alternate Exterior Angles
4. [tex]\angle 3[/tex] and [tex]\angle 9[/tex] are Consecutive Interior Angles
Step-by-step explanation:
Alternate Interior Angles - When a pair of angles are in the interior in the opposite sides of the transversal.
Alternate Exterior Angles -When a pair of angles are in the outside in opposite sides of the transversal.
Corresponding Angles - When a pair of angles are in the same side of one of two sides by a cross-section.

Step-by-step explanation:
Someone invested some money at 8% and $300 more than
twice this amount at 12%. Her total annual income from
the two investments is $548. How much is invested at
each rate?
32
Answer:
$1600 at 8% and 3500 at 12%
Step-by-step explanation:
The rule of the interest is I = PRT, where
P is the amount of investment R is the rate in decimalT is the timeAssume that the amount of money is $x
∴ P = x
∵ The rate is 8%
∴ R = 8/100 = 0.08
∵ She has an annual income
∴ T = 1
→ Substitute them in the rule to find the interest amount
∴ I = x × 0.08 × 1
∴ I = 0.08x
∵ She invested $300 more than twice the previous amount
∴ P = 2x + 300
∵ The rate is 12%
∴ R = 12/100 = 0.12
∵ T = 1
→ Substitute them in the rule to find the other interest amount
∴ I = (2x + 300) × 0.12 × 1
∴ I = 0.24x + 36
∵ Her total annual income from both investments is $548
→ Add the two amount of interest and equate their sum by 548
∴ 0.08x + 0.24x + 36 = 548
→ Add the like terms in the left side
∴ 0.32x + 36 = 548
→ Subtract 36 from both sides
∴ 0.32x + 36 - 36 = 548 - 36
∴ 0.32x = 512
→ Divide both sides by 0.32
∴ x = 1600
∴ She invested $1600 at 8%
→ Substitute x by 1600 in the expression of the other amount to find it
∵ 2x + 300 = 2(1600) + 300 = 3500
∴ She invested $3500 at 12%
Biologist Dr. Cytoplasm wants to know how many elephants in the nature reserve have broken tusks . Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks. Of the 600 elephants in the reserve, how many can he expect to have broken tusks?
Answer:
Of the 600 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}(600)=160[/tex] elephants with broken tusks.
Step-by-step explanation:
Let x denotes number of elephants having broken tusks out of 600 elephants.
Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks.
So,
Of the 1 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}[/tex] elephants with broken tusks.
Therefore,
Of the 600 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}(600)=160[/tex] elephants with broken tusks.

Answer: terminating repeating decimal
Step-by-step explanation: In the subject of Mathematics, we usually classify numbers in several types: whole numbers, rational numbers, natural numbers, and real numbers. We also include decimals in these types. Decimals are used by us to convey a whole number and a fraction together. We do this by separating a whole number from the adjoining fraction by inserting “.” between them. This symbol is called a decimal point. In other words, decimals are just another way of representing fractions.

(b) About how many times larger was the population of the United States than the population of Columbus, Ohio?
Answer:
387.6. So, the closest whole number would be 388 times larger
Step-by-step explanation:
I divided the U.S. pop by the Columbus pop and got the answer: 387.6. So, the closest whole number would be 388 times larger
Answer:
The population of the United States is 387.87 times larger than the population of Columbus, Ohio.
Step-by-step explanation:
8.25 times 100000 = 825,000
3.2 times 100000000 = 320,000,000
320,000,000 divided by 825,000 = 387.87
Enter a graph compound inequality for the numbers described. Use x as the variable.

Answer:
If y> or y>=, (>= means greater than or equal to), then you shade up. If y< or y<=, (<= means less than or equal to), then you shade down. I remember this by up: greater (because when something is bigger, it's higher) and down: less (because if it's smaller, it's lower). I hope that helps.

Answer:
$16
Step-by-step explanation:
20/5 = 4
4 x 4 = 16
Have a good day!
==================================================
Work Shown:
5 notebooks = 20 dollars
5/5 notebooks = 20/5 dollars ..... divide both sides by 5
1 notebook = 4 dollars ..... unit rate
4*(1 notebook) = 4*(4 dollars) .... multiply both sides by 4
4 notebooks = 16 dollars
---------------
Another approach:
(5 notebooks)/(20 dollars) = (4 notebooks)/(x dollars)
5/20 = 4/x
5*x = 20*4 ... cross multiply
5x = 80
5x/5 = 80/5 .... dividing both sides by 5
x = 16
So 4 notebooks cost $16

An inchworm is crawling up a tree. It begins 18 inches above the ground and climbs up 3 inches every minute. Let t represent the number of minutes since the worm began climbing. Veronica wants to know when the inchworm will be more than 60 inches above the ground. Which inequality should she use?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Starting point = 18 inches
Rate or speed = 3 inch per minute
t = number of minutes since climbing began
When will worm be more than 60 inches above the ground.
Height (t) = starting point + (rate * time)
18 + 3t > 60
3t > 60 - 18
3t > 42
t > 42/3
t > 14
Hence, inequality to use is : 60 > 18 + 3t
What are the solutions of 6t-1> 4t+13
answer:t>7
6t - 1> 4t + 13 Move the terms 6t - 4t> 13 + 1 Group the like terms Calculate 2t> 14 Divide both sides Solution t> 7 Alternate between E (7, + 0) Explain the steps> II

-5a + 15/2a - 25 = 53.2 + 21.8
Answer:
a= 40
Step-by-step explanation:
-5a + 7.5a - 25 = 53.2 + 21.8
add like terms on both sides: 2.5a - 25 = 75
add 25 on both sides: 2.5a = 100
divide both sides by 2.5: a = 40
Answer:
a = 40
Step-by-step explanation:
-5a + 15/2a - 25 = 53.2 + 21.8: Add 25 to Isolate variable
-5a + 15/2a = 53.2 + 21.8 + 25: Combine Like Terms and create simmilar terms
-10/2a + 15/2a = 100: CLM again
5/2a = 100: multiply both sides by inverse of 5/2 to isolate variable
a = 40
