1. k/12 = 12

can also be written as

k/12 = 12/1

we can cross multiply

k · 1 = 12 · 12

k= 144

2. -110/5 = x

can also be written as

-110/5 = x/1

we can cross multiply

-110 · 1 = 5 · x

-110 = 5x

-22 = x

3. w/-6 =30

can also be written as

w/-6 = 30/1

we can cross multiply

w · 1 = 30 · -6

w = -180

hope this helps

K/12=12. multiply both sides by 12 to isolate the k. you get k=144

2is -22. some division on the calculator

4. multiply both sides by-6 to get w=-180

can't see any more

Answer:

5000 ft.

Step-by-step explanation:

Refer the attached figure .

AC is the distance of hulk from home

Since ΔABC is right angled triangle. we will use pythagorus theorem.

$Hypotenuse^{2} =Perpendicular^{2} +Base^{2}$

Hypotenuse = AC

Perpendicular = AB=6 blocks

Base = BC = 8 blocks

⇒ $AC^{2} =AB^{2} +BC^{2}$

⇒ $AC^{2} =6^{2} +8^{2}$

⇒ $AC^{2} =36+64$

⇒ $AC^{2} =100$

⇒ $AC =\sqrt{100}$

⇒ $AC =10$

Thus AC = 10 blocks .

Since we are given each block is 500 ft.

Thus 10 blocks = 500*10=5000ft.

Hence hulk is 5000 ft away from the home

Tamara and Jason work at a widget factory. Tamara arrived at work before Jason and began making widgets. Tamara had already made

Mrac [35]

Answer:

See explanation!

Step-by-step explanation:

The remaining question reads:

Part A: Write a system of equations to represent the situation. Let x = hours and y = widgets.

Part B: How much time does it take for Tamara and Jason to produce the same number of widgets?

Part C: How many widgets will Tamara and Jason have produced?

-------------------------------------------------------------------------------------------------------------

To solve this problem we can construct an linear algebraic expression for each person, principally denoted as:

$y=ax+c$

where

$y$ :is our dependent variable (which is a function of $x$ )

$x$ :is our independent variable

$a$ :is the slope

$c$ :is the y-intercept constant value (if any present)

Part A: Write a system of equations to represent the situation. Let x = hours and y = widgets.

Tamara

Has already made 20 widgets and produces at a rate of 8 widgets per hour thus here $c=20$ and $a=8$ , so Tamara's equation reads:

$y_{T}=8x+20$

Jason

Has not produced any widgets yet and produces at a rate of 12 widgets per hour thus here $c=0$ and $a=12$ , so Jason's equation reads:

$y_{J}=12x$

So the system of equations will be

$y_{T}=8x+20\\y_{J}=12x$

Part B: How much time does it take for Tamara and Jason to produce the same number of widgets?

Since we want to find the amount of time (i.e. the value of $x$ ) it takes for both of them to produce the same number of widgets we can just equate the two equations ans solve for $x$ as follow:

$y_{T}=y_{J}\\8x+20=12x\\8x-12x=-20\\-4x=-20\\x=\frac{-20}{-4}\\ x=5$

So it takes them 5 hours to produce the same amount of widgets.

Part C: How many widgets will Tamara and Jason have produced?

Now we can simply plug in the value of $x=5$ in any of the two equations (i.e. either for Tamara or Jason) to find the number of widgets produced.

$y_{T}=8(5)+20=40+20=60$

So in a time-space of 5 hours Each will have produced 60 widgets and in total will be 60+60 = 120 widgets.

How to take away a improper fraction

spin [16.1K]

Answer:

The rules for adding and subtracting improper fractions are the same as working with proper fractions. Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. Step 3: If the answer is an improper form, reduce the fraction into a mixed number.

tangare [24]

A = P(1+r/n)^(nt)

133,000 = 98,000(1+x/1)^(1(5))

1.36 = (1+x)^5

1.063 = 1+x

x = .063 or 6.3%
