Which pair represents isotope? a.30 32 15 x and i5 34 19 3?

Find the slope that is perpendicular to the graph of the equation y-2x=-5

Sloan [31]

We can rearrange the initial equation to y=mx+b

y=2x-5

Since perpendicular slopes must equal -1,
x=the perpendicular slope
2x=-1
x=-1/2

(Or you can just take the negative reciprocal above is just the "formula form" for it)

Therefore, the perpendicular slope is -1/2

Based on the information given, it can be noted that the final price of the item will be $74500.

<h3>Solving percentages.</h3>

From the information given, Me Sanchez wants to purchase a camper, which is on sale for 10% off the original price of $85,000 and the manufacturer is offering a $2500 rebate.

Therefore, the final price will be:

= $85000 - (10% × $85000) - $2500

= $85000 - $8500 - $2000

= $74500.

Round each measurement to the nearest ten. Then estimate the area of the rectangle.

Ainat [17]

Answer:

4000 sq inches

Step-by-step explanation:

A rectangle is given with sides 82 and 46 inches

We have to round off these dimensions to the nearest 10.

82 inches ~80 inches since 2 <5, we make it 0

Similarly 46 inches ~50 inches since 6>5

Now area

= length x width

=80(50)

=4000 square inches

Option 2 4000 sq inches is correct answer.

Set up an equation and solve the following problem.

nordsb [41]

Answer:

The speed of Dave is 42 miles per hour

The speed of Kent is 46 miles per hour .

Step-by-step explanation:

Given as :

The distance cover by Dave = d = 210 miles

The time taken by Dave = t hour

The speed of Dave = s miph

Again

The distance cover by Kent = D = 230 miles

The time taken by Kent = T hour

The speed of Kent = S = (s + 4 ) miph

For Dave

Time = $\dfrac{\textrm Distance}{\textrm Speed}$

So, t = $\dfrac{\textrm d miles}{\textrm s miph}$

Or, t = $\dfrac{\textrm 210 miles}{\textrm s miph}$

For Kent

Time = $\dfrac{\textrm Distance}{\textrm Speed}$

So, T = $\dfrac{\textrm D miles}{\textrm S miph}$

Or, T = $\dfrac{\textrm 230 miles}{\textrm (s + 4) miph}$

∵ Time taken by both is same

So, t = T

Or, $\dfrac{\textrm 210 miles}{\textrm s miph}$ = $\dfrac{\textrm 230 miles}{\textrm (s + 4) miph}$

Or, 210 × (s + 4) = 230 × s

Or, 210 × s + 210 × 4 = 230 × s

Or, 210 × 4 = 230 × s -210 × s

Or, 210 × 4 = 20 × s

∴ s = $\dfrac{840}{20}$

i.e s = 42 miph

So, The speed of Dave = s = 42 miles per hour

Again

The speed of Kent = S = (s + 4 ) miph

i.e S = 42 + 4

or, S = 46 miph

So, The speed of Kent = S = 46 miles per hour

Hence,The speed of Dave is 42 miles per hour

And The speed of Kent is 46 miles per hour . Answer
