Answer:

28.1%

Step-by-step explanation:

A town's population in 2019 was 438,000. The town's current population is 561,000. What is the percent of change?

The formula for Percent change =

Final value - Initial value/Initial value × 100

= 561000 - 438000/438000 × 100

= 123000/438000 × 100

= 28.082191781%

Approximately = 28.1%

Therefore, percent change = 28.1%

Step-by-step explanation:

The amount after 3 years will be $ 21,206.6

To understand more, check below explanation.

If the amount P is invested at the rate of r% for n years.

Then amount after n years is computed as;

Given that, Principal = $8,800 , r = 7% and n = 13 years.

                   [tex]A=P(1+\frac{r}{100} )^{n}\\ \\A=8800(1+\frac{7}{100} )^{13} \\\\A=8,800*(\frac{107}{100} )^{13}\\ \\A=\$ 21206.6[/tex]

Hence, the amount after 13 years will be $ 21,206.6

Step-by-step explanation:

Here, we want to plot the graph of y = 6-2x on the grid

We can rewrite this to look like the general form as;

y = -2x + 6

The y-intercept is 6

This point is (0,6)

For the x-intercept, equate y to 0

0 = -2x + 6

2x = 6

x = 6/2

x = 3

The x-intercept is (3,0)

So we have to join the point (3,0) with (0,6)

Answer:

D

Step-by-step explanation:

Either try all the numbers and see which ones work or do the following.

Times both sides by 2x-5.

3=x(2x-5)=2x^2-5x

Rearrange and solve the quadratic. I will factorise.

2x^2-5x-3=0

(2x+1)(x-3)=0

so x = -1/2 or 3

Answer:

its

x = A/4y

Explanation:

when we send 4 and Y to the left hand side, their signs changes from multiplication to division and since they were in the numerator, they go to the denominator on the other side.

Answer:

x = 20

Step-by-step explanation:

2x + 20 = 3x

2x - 2x + 20 = 3x - 2x

20 = x

2x + 20 = ?

2(20) + 20 = ?

40 + 20 = ?

60 = ?

3x = ?

3(20) = ?

60 = ?

Step-by-step explanation:

Look at the graph they gave you. ... At first it looks like an ugly mess.

But look closer.  There are only two lines there that go through the origin,

so one of those is the answer to the question.

Now let's talk about the slope of a line.

-- If the slope of a line is positive, that means it rises as it goes.

  If you walk the graph from left to right, you're climbing.

-- If the slope of a line is negative, that means it falls as it goes.

  If you walk the graph from left to right, you're going down-hill.

The equation they gave you is  [ y = 1/2 x ].

The slope is  1/2 .  That's positive.

The line on the graph slopes up.  To walk it, you have to climb.

In the picture, that can only be line 'c' .

Answer:

The equation they gave you is  [ y = 1/2 x ].

The slope is  1/2.  That's positive.

2.5 m/s

Step-by-step explanation:

Matty's speed = 9 km/hr

We need to convert 9 km/hr to m/s

We know that,

1 km = 1000 m

1 hour = 3600 seconds

[tex]v=9\times \dfrac{1000\ m}{3600\ s}\\\\=2.5\ m/s[/tex]

Answer:

Step-by-step explanation:

Cost of the camera at one store,

Down payment = $49

Per month payment = $20

Duration of the payment = 12 months

Total payment to be done = down payment + payments to be done in 12 months

= 49 + (20×12)

= 49 + 240

= $289

Cost of the camera at second store,

Equation describing the payment plan,

y = 15x + 79

Here, x = number of months

y = Total amount to be paid

If x = 12 months

y = (15×12) + 79

y = 180 + 79

y = $259

The camera at the second store is cheaper when the camera is paid off in 12 months because the cost at the first store is $289 and the cost at the second store is $259.

Answer:

3 1/6 miles

Step-by-step explanation:

Rate(Speed )= Distance/Time

From the Question, we are to find the distance.

The formula for Distance = Rate × Time

Rate = 19/2 mile per hour

Time = 1/3 of an hour.

Distance = 19/2 miles per hour × 1/3 hour

= 19/6 miles

= 3 1/6 miles

Donna can travel 3 1/6 miles in 1/3 of an hour
