at the beginning of summer, a maintenance crew refills a swimming pool at a city part. the relationship between the time in hours to fill the pool and the amount of water in the pool is proportional.
after 4 hours, the pool holds 5,200 gallons of water. b. the same crew refills a second pool as represented by the graph shown. is the second pool filled at a faster or slower rate than the first pool? explain.

Answer:

X=7

take the -21 to the other side of the equation, when you do this it goes from a negative to a positive so we now have 63+21=12x

if we add 63 and 12 we get 84 decide by 12 because we have 12x and we get 7

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.

Answer: x is equal to 4

Step-by-step explanation:

A triangle's angles sums up to 180°. So we already know that the three angles in this triangle add up to 180°. The equation would be as following.

(18x - 12) + 15x + (10x + 20) = 180

We first add like terms together.

43x + 8 = 180

We then substract 8 on both sides.

43x = 172

We finally divide 43 on both sides.

x = 4

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

2 y + 10 = 9 x + 63

- 9 x + 2 x = 53

Answer:

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

Answer:

Option C is correct

Step-by-step explanation:

Point slope form:

The equation of line is given by:

    ....[1] where m is the slope and a point  lies on the line.

Given that:

A line passes through (-7,-5) and (-5,4).

Calculate  slope:

Slope is given by:

Substitute the given values we have;

Simplify:

Substitute thee value of m and (-7, -5) in [1] we have;

Simplify:

⇒

Using distributive property :

Subtract 9x from both sides we have;

Subtract 10 from both sides we have;

Therefore, an equation for the line in point-slope form is  and the equation in standard form using integers is

Answer:

660 square feet

Step-by-step explanation:

1 chain = 66 feet

Length ( l ) = 66 feet

Breadth ( b ) = 10 feet

To find :

The area of a cricket pitch in square feet = ?

The area of a cricket pitch in square feet will be in the shape of rectangle.

Formula : -

Area of a rectangle = lb

Area of a rectangle

= 66 x 10

= 660 square feet

Therefore,

660 square feet is the area of a cricket pitch.

Answer:

660

Step-by-step explanation:

I chain = 22 * 3 so to find the area we have to do (22*3) * 10 = 660

x = 16 or [tex]\frac{-8 + x}{4} = 2[/tex]

Step-by-step explanation:

let's start from the beginning and move along!

[tex]\frac{-8 + x}{4}[/tex] = 2

to solve this...

1) multiply both sides by four to get rid of the fraction

[tex](4)\frac{-8 + x}{4} = 2(4)[/tex] ------> -8 + x = 8

2) add 8 to both sides to isolate x ----> x = 16

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2 (y + 9 - 3y)

Adding like terms.

2 (9 - 2y)

Removing the parenthesis.

2 x 9 - 2 x 2y

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.
