Find the area of the circle from the given radius.
r = 2 ft
a
6.28 ft2
b 12.56 12
c 15.27 ft?
d 8.26 ft2

Solution :

It is given that the Precision Scientific Instrument company Manufactures thermometers that provide readings at 0 degree Celsius for the freezing point of water.

A quality control analyst examines the thermometers which provide readings in the bottom of 4%.

Using the standard normal table, we get

P(z < z) = 4%

P(z < z) = 0.04

See the probability of 0.04 in the standard normal corresponding to the z-value is = -1.75

Therefore,

P(z < -1.75) = 0.04

z = -1.75

So the temperature reading that separates the bottom of 4% from the other thermometers is - 1.75°C

Therefore correct option is (D). -1.75

Answer:

for the first 14 hours it doubles to 20,000, then once it reaches 28 hours it'll be 40,000. its an exponential growth

The population growth of bacteria after 28 hours will be equal to 40,000.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the set of information in the question,

Total population of Bacteria = 10,000

Rate of growth of bacteria = Twice in 14 hours

Rate of growth in 28 hours = 4 times the total population.

Then the total bacteria (B) in the colony after 28 hours,

B = 4 × 10,000

B = 40,000

Answer:

a = 11

b = 33

Step-by-step explanation:

Given :

Total fossil found = 33

Let :

Number of plant fossil = b

Number of animal fossil = a

a + b = 33

Plant fossil = 2 times number of animal fossil

b = 2a

Put b = 2a

a + 2a = 33

3a = 33

Divide both sides by 3

3a/ 3 = 33/3

a = 11

a + b = 33

11 + b = 33

b = 33 - 11

b = 22

btw its 557/1980

The proof is shown in the solution.

A repeating decimal or recurring decimal is a decimal representation of a number whose digits are periodic, and the infinitely repeated portion is not zero.

Given that, show that the recurring decimal 0.2813 = 557 / 198

Let 0.2813 be x

0.2813 = x......(i)

2813.2813 = 10000x......(ii)

Subtracting eq(i) from eq(ii)

2813 = 999x

x = 2813 / 999

x = 557 / 198

Hence, proved

Answer: 197.82mm³

Step-by-step explanation:

Volume of a cylinder = πr²h

where,

π = 3.14

r = Diameter/2 = 6mm/2 = 3mm

h = 7mm

Volume = πr²h

= 3.14 × 3² × 7

= 3.14 × 9 × 7

= 197.82mm³

The volume of the cylinder is 197.82mm³

Answer:

l = 1 5/16

w = 1/16

A = 21/16 x 1/16 = 21/256

Step-by-step explanation:

Perimeter = 11/4

l = length

w = l - 5/4

2l + 2(l - 5/4) = 11/4

2l + 2l - -5/2 = 1/4

multiply each side by 4

8l + 8l - 10 = 11

16l = 21

l = 21/16 or 1 5/16

width = 21/16 - 20/16 = 1/16

Answer:

Value of house in 2021 = $627,680 (Approx.)

Step-by-step explanation:

Given:

Value of house in 2009 = $200,000

Rate increased per year = 10% annually

Find;

Value of house in 2021

Computation:

Number of year = 2021-2009 = 12 year

Value of house in 2021 = Value of house in 2009[1+Rate increased per year]ⁿ

Value of house in 2021 = 200,000[1+10%]¹²

Value of house in 2021 = 200,000[1+0.1]¹²

Value of house in 2021 = 200,000[1.1]¹²

Value of house in 2021 = 200,000[3.1384]

Value of house in 2021 = $627,680 (Approx.)

Step-by-step explanation:

If 3y>27, then y>9. Therefore, D is the correct answer (C is not correct BTW because 9 isn't included in the inequality).

Answer: There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.

AB = 13200 miles

AO = 4000 miles

OB = 4000 miles

Let us assume CB = x

Then

(x + 4000)^2 = (13200)^2 + (4000)^2

x = sqrt(13200^2 + 4000^2) - 4000

= 13793 - 4000

= 9793 miles.

From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.

Answer:

13 quarts

Step-by-step explanation:

Remember this:

1 mug = 16 oz

1 quart = 32 oz

Find total quarts of coffee.

Setup proportion and solve for x ounces:

[tex]\frac{1 mug}{16 oz} =\frac{26 mugs}{xoz}\\\\x oz=16(26)=416 oz[/tex]

Setup another proportion to solve for x quarts and also use the 416 oz.

[tex]\frac{32oz}{1 qt} =\frac{416oz}{xqt} \\x=\frac{416}{32} = 13 qt[/tex]
