Answers

it’s c! 36 x 10^6 that’s what I got when I completed the problem

Answer:

C: 36 × 10^6 m²

Step-by-step explanation:

Given the side length of a square = 6 × 10³m,

To solve for the area of a square, use the following formula:

A = S² where:

S = side of the square

Substitute the given value for the side into the formula:

A = S²

A = (6 × 10³)²

A = 36000000 or 36 × 10^6 m²

NOTE:

6 × 10³ is also the same as 6 × 1000 = 6000,

(6 × 10³)² is essentially 6,000² = 36,000,000

Therefore, the correct answer is C) 36 × 10^6

A cricket pitch measures 1 chain by 10 feet. What is the area of a cricket pitch in square feet?

please answer it correctly ​

Answers

Step-by-step explanation:

4.

GCF : greatest common factor, the biggest number all these numbers can be divided by without remainder.

so, 15, 30 and 45

let's find the basic factors of each

15/2 no

15/3 = 5

5/3 no

5/4 no

5/5 = 1

therefore, 3¹×5¹

30/2 = 15

15/3 = 5

5/3 no

5/4 no

5/5 = 1

therefore, 2¹×3¹×5¹

45/2 no

45/3 = 15

15/3 = 5

5/3 no

5/4 no

5/5 = 1

therefore, 3²×5¹

the largest combination of factors they all have is 3¹×5¹ = 15

so, the GCF = 15.

5.

since I don't know how many pupils there are this is a strange question.

or does this text mean there are 5 pupils ?

overall, there is something wrong with this question.

so, let's answer based on some assumptions :

the GCF (as in 4.) is 12

12×3 = 36

12×4 = 48

12×5 = 60

so, if there are 12 students, each one gets 5 notebooks, 4 ball pens and 3 correction tapes.

if there are 5 students, then each one gets 60/5 = 12 notebooks, 48/5 = 9 (3 remainder) ball pens and 36/5 = 7 (1 remainder) correction tapes.

6.

multiples of 4, that means 4*x with x = 1, 2, 3, 4, ...

so

4×1 = 4

4×2 = 8

4×3 = 12

4×4 = 16

therefore, B is the right answer.

Vera's piggy bank contained $10.90 in quarters, dimes, and nickels. There were six more than two times as
many nickels as quarters and four less than two times as many dimes as quarters.
Create an equation to represent the situation.

Answers

Answer:

[tex]6+2n+4-2d\cdot n = 1090[/tex]

Step-by-step explanation:

We have to convert everything to the same value. For example, 8$ would be 8 cents. And 1 Nickle would be 5 cents.

n = number of nickles

d = the number of dimes

q = number of quarters

1 nickle = 5 cents

1 dime = 10 cents

1 quarter = 25 cents

Step 1: Convert the total amount from dollars to cents.

There were $10.90 in total. Since there are 100 Cents in 1 Dollar, there would be 1090 cents in 10.90 dollars. (Tip you can easily find how many cents there are in dollars if you simply remove the decimal ".")

We are converting this because we need to have every value in the same term.

Step 2: Convert all of the amounts to cents.

Linear pair means a pair of adjacent angles formed when two lines intersect, and their sum is 180°

In the question it want one of the angles to be 16° more then the other, so the measures of the angles will be

164/2 = 82

Angle 1 = 82°    Angle 2 = 82°+16 = 98°

Draw a straight angle (straight line), intersect it with another line such that the two angles that will be formed one of them will be of measure 98° and the other 82°

a variable x has a normal distribution with mean 54 and standard deviation 5. approximately what percentage of the observations will fall between 44 and 64?

Answers

For a normal distribution with mean 54 and standard deviation 5 95.4% of them fall between 44 and 64

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean.\sigma=standard\ deviation, x=raw\ score\\\\Given\ that\ mean(\mu)=54,standard \ deviation (\sigma)=5\\\\For\ x=44:\\\\z=\frac{44-54}{5}=-2\\\\For\ x=64:\\\\z=\frac{64-54}{5}=2[/tex]

Therefore., from the normal distribution table:

P(44<x<64) = P(-2< z < 2) = P(z < 2) - P(z < -2) = 0.9772 - 0.0228 = 0.9544

Hence, About 95.4% of them fall between 44 and 64.

The unit measure for atmospheric pressure is kPa (Kilo-Pascals). At sea level the standard
atmospheric pressure is 101.3 kPa. For every 1000 feet increase in altitude, atmospheric
pressure decreases by 1.8 kPa. What is the atmospheric pressure at 50,000 feet?

Answers

The pressure change is an illustration of an arithmetic progression.

The atmospheric pressure at 50000 feet is 11.3 kPa

The given parameters are:

[tex]\mathbf{a = 101.3}[/tex] --- the first term

[tex]\mathbf{d = -1.8 per 1000}[/tex] -- common difference

At 50000 feet, the number of increment in altitude is

[tex]\mathbf{n = \frac{50000}{1000}}[/tex]

[tex]\mathbf{n = 50}[/tex]

So, the atmospheric pressure at 50000 feet is:

[tex]\mathbf{T_{50} = 101.3 - 1.8 \times 50}[/tex]

[tex]\mathbf{T_{50} = 101.3 - 90}[/tex]

[tex]\mathbf{T_{50} = 11.3}[/tex]

Hence, the atmospheric pressure at 50000 feet is 11.3 kPa

Answer:

-5/6a - 5/8

Step-by-step explanation:

In order to to simplify the linear expression you must combine like terms.

"like terms" are terms whose variables and exponents are the same. for example 2x and x are like terms. In this case, -2/3a and -1/6a are like terms as they have the same variable (a) and exponent (1). -2/3a - 1/6a = -4/6a - 1/6a = -5/6a

Next, we combine the constants 1/8 and -3/4. 1/8 - 3/4 is the same as 1/8 - 6/8 which is equal to -5/8. Therefore the final simplified linear expression is -5/6a -5/8.

Answer:

b. y + 5 = 9/2 ( x + 7 ) ;   - 9 x + 2 y = 53

Step-by-step explanation:

The equation:

y - y 1 =  ( y2 - y1 ) / ( x2- x1) * ( x - x1 )

y - ( - 5 ) = ( 4 + 5 ) / ( - 5 + 7 ) * ( x - ( - 7 ) )

y + 5 = 9/2 ( x + 7 )

y + 5 = 9/2 x + 63 /2  / * 2
