Write an expression to represent the water temperature after the submarine’s final dive. Then simplify the expression to find the temperature.

Answer:

Step-by-step explanation:

Given the original coordinate as C (-6, 9) and new coordinates after dilation as C' (-2, 3), we can see that the value of the new coordinates has reduces by a factor. Let the factor be k

For the x coordinates:

C' = kC

x' = kx

-2 = k(-6)

-2 = -6k

Divide both sides by -6

k = -2/-6

k = 1/3

For the y-coordinates:

y' = ky

3 = 9k

Divide both sides by 9:

3/9 = 9k/9

1/3 = k

k = 1/3

Hence the scale factor of the dilation is 1/3

Answer:

The scale factor from C' to C is

3

But the scale factor from C to C' (the one you may have asked for in the question) is

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

What we already know is that we have line segments C and C' and we know their lengths.

C = (-6, 9)

C' = (-2, 3)

So the scale factor from C' to C can be easily known if we simply use the rules of division

-6 ÷ -2

and

9 ÷ 3

They both are equal to the outcome, 3.

So we now know that the scale factor from C' to C is 3.

But what about C to C'??

Yes we still have to do division, BUT (you may have guessed it already but), we must switch the positions that the numbers for dividend and divisor were.

-2 ÷ -6 =

0.33333333...  or  [tex]\frac{1}{3}[/tex]

3 ÷ 9 =

0.33333333...  or  [tex]\frac{1}{3}[/tex]

So we can decisively conclude that the scale factor of C to C' is [tex]\frac{1}{3}[/tex]

Answer:

She earns $18.20 dollars per hour

Step-by-step explanation:

$546 (how much she is payed each week) ÷ 30 (how many hours she works each week) = $18.20 (how much she earns per hour)

The solution is, the value of the inequality is, 3  ≥ k.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

given that,

15 - 5k ≥ 0

now, we get,

Start by adding 15 to both sides

15 + 15 will cancel out

15 + 0 = 15

After you are left with just 5k and 15

Divided 5 on both sides of the inequality

5k/5 ( this will cancel out)

15/5 = 3

Bring down the k & inequality sign

3 - k  ≥ 0

adding k on both side,

3  ≥ k

Final Answer : 3  ≥ k

Answer:

250 berries

Step-by-step explanation:

There are 10 berries to every orange there is. It is given that there are 25 oranges. Simply multiply 10 with 25:

10 x 25 = 250

There are 250 berries.

~

Answer:

There are 250 berries.

Step-by-step explanation:

There are 10 berries per 1 orange.

We have 25 oranges.

To find out how many groups of berries to oranges there will be I will divide 25 by 1.

[tex]25/1=25[/tex]

[tex]x*y=z[/tex]

x = Amount of groups

y = Amount of berries per group

z = Amount of berries total.

Substitute values:

[tex]25*10=250[/tex]

There are 250 berries total!

Step-by-step explanation:

30% + 20% = 50% = half price

if he pays 112 whick is half price you need to times it by 2 to get the full price

1.75, 1.5, 1.25, 1, 0.75, 0.5, 0.25, 0

(Idk if 0 would be considered to be positive but the rest are for sure.)

To find these just subtract 0.25 each time until you hit a negative number.

Answer:

4091

Step-by-step explanation:

Given the equation;

3x + 7x − 28 + 31 − 8x

First, we would collect like terms;

3x + 7x − 8x − 28 + 31

Simplifying, we have;

[tex] 2x + 5[/tex]

For x = 2043;

2(2043) + 5 = 4086 + 5 = 4091.

Answer:

y = -5/4x - 10.75

Step-by-step explanation:

First, put the equation in slope intercept form by isolating y:

5y - 4x = 10

5y = 4x + 10

y = 4/5x + 2

Perpendicular lines have opposite reciprocal slopes, so the slope will be -5/4

Plug in the slope and the given point into y = mx + b to find b:

y = mx + b

8 = -5/4(-15) + b

8 = 18.75 + b

-10.75 = b

Plug in the slope and y intercept into y = mx + b

y = mx + b

y = -5/4x - 10.75

Answer:

5x + 4y + 43 = 0

Explanation:

y=mx+b

m=slope

b=y intercept

perpendicuar lines have slopes that multiply to get -1

so

solving for y

add 4x both sides and divide by 5 to get

y=4/5x+2

slope is 4/5

perpendicular means the slopes multiply to get -1

so

4/5 times what=-1?

what=-5/4

so

y=(-5/4)x+b

find b

given the point (-15,8)

8=(-5/4)(-15)+b

8=75/4+b

-43/4=b

y=(-5/4)x-43/4

convert to standard form:

5x + 4y + 43 = 0
