Percent change from 45 to 56

makkiz [27]

The percentage of change from 45 to 56 is 24.4%

To find this, we first need to find the difference between our two values. This difference would be 11.

The next step would be to divide 11 by 45. We then move the decimal point over two spots to the right which gives us our answer.

What is the value of x?

GrogVix [38]

Answer:

Step-by-step explanation:

The two triangles $\triangle MNP\sim \triangle RST$ .

Therefore the corresponding sides are proportional.

$\frac{|ST|}{|PN|} =\frac{|TR|}{|MP|}$

From the diagram |MP|=4, |PN|=3, |MN|=5 |ST|=x and |TR|=12.

Let us substitute the values and solve for x.

$\frac{12}{4}=\frac{x}{3}$

Multiply both sides by 3 to get:

$3*\frac{12}{4}=\frac{x}{3}*3$

This implies that:

$9=x$

Therefore x=9

L and ben are drivers for sd trucking company. one snowy day, ben left sd at 8:00

Whitepunk [10]

Alright, lets get started.

Ben left at 8:00 AM and Al left at 11:00 AM.

Suppose dispatcher retrieves data after t hrs when Al left SD.

We know the average speed of Al = 40 miles per hr

So, distance covered by Al = Time * speed

Distance covered by Al = 40 t

We know average speed of Ben = 20 miles per hr

As we know Ben left SD 3 hrs before, time taken by Ben will be 3 hrs higher than AL means (t+3)

So distance covered by Ben = $20 (t + 3)$

Total distance covered by both will be = $40 t + 20 (t+3)$

Total distance covered by both will be = $40 t + 20 t + 60$

Total distance covered by both will be = $60 t + 60$

But as per given in question, total distance covered by both is 240 miles.

Hence making both equal,

$60 t + 60 = 240$

Subtracting 60 from both sides

$60 t + 60 - 60 = 240 - 60$

$60 t = 180$

Dividing 60 in both sides

$\frac{60 t }{60} = \frac{180}{60}$

t = 3 hrs

It means it was 11:00 AM + 3 hrs means 2:00 PM when dispatcher retrieve data. : Answer

Hope it will help :)

Help plzz<br> Find the slope of the line that contains the points (-2, 5) and (-1, 7)

larisa86 [58]

Use the slope formula.
Subtract the y-coordinates.
Subtract the x-coordinates in the same order.
Divide the difference in y by the difference in x.

slope = m = (y2 - y1)/(x2 - x1)

slope = (5 - 7)/(-2 - (-1)) = -2/(-1) = 2

slope = 2
