314,880

Step-by-step explanation:

If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.

Answer:

x=16

Step-by-step explanation:

27/45=(2x+7)/(4x+1)

cross multiply

27(4x+1)=45(2x+7)

108x+27=90x+315

108x-90x=315-27

18x=288

x=288/18

x=16

Looking at the image, The triangle shown below are similar. The value for  x is 16.

Note that in the triangle given, the shapes are similar. Therefore:

27/45 = 2x + 7/  4x + 1

3/5 = 2x + 7/  4x + 1

So:

3 (4x + 1) = 5 (2x + 7)

12x + 3 = 10x + 35

12x - 10x = 35-3

2x = 32

x = 32/ 2

x = 16

Therefore, the value of x is 16.

Answer:

In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

Answer:

1: b. YZ, see "geometric mean theorem" in Wikipedia

2: a. sin Y = 7.4/10.9 ≈ 0.68,  sine = opposite/hypotenuse

3: c. tan P = 8.5/16 ≈ 0.53, tangent=opposite/adjacent

4: a. AC = 11.7, sine = opposite/hypotenuse, sin(43) = 8/AC

5. KM = 10.68 use Pythagorean Theorem

The term that completes the equation is YZ.

Option D is the correct answer.

We have,

From the figure,

∆WXY and ∆XYZ

∠WXY = ∠XZY = 90

∠ZYX = ∠XYW (common angle)

∆WXY ≅ ∆XYZ

And,

∆WXY and ∆WXZ

∠WXY = ∠WZX = 90

∠YWX = ∠XWZ (common angle)

∆WXY ≅ ∆WXZ

Now,

From (1) and (2),

∆XYZ ≅ ∆WXZ

This means,

The corresponding sides are proportional.

We can write as,

YZ/XZ = XZ/ZW

XZ² = WZ x YZ

Thus,

The term that completes the equation is YZ.

Answer:

[tex]x = \frac{ - 63}{2} \: or \: - 31.5[/tex]

Step-by-step explanation:

[tex] \frac{x}{7} - \frac{x}{9} = - 1[/tex]

Lets take the L.C.M of 7 & 9.

L.C.M of 7 & 9 = 63

[tex] = > \frac{9x - 7x}{63} = - 1[/tex]

[tex] = > \frac{2x}{ 63} = - 1[/tex]

Now lets multiply 63 on both the sides.

[tex] = > 2x = - 63[/tex]

Now lets divide both the sides by 2.

Answer: 19.2 cm

Step-by-step explanation:

A meter is equal to 100 centimetres so the total length of Tia's wire in centimetres is:

= 4.08 * 100

= 408 cm

She cuts this into 10 equal pieces:

= 408 / 10

= 40.8 cm

Martha cuts her 540 cm wire into 9 pieces. Each piece is:

= 540 / 9

= 60 cm each

The difference is:

= 60 - 40.8

= 19.2 cm

Y intercept : ( 0 , 25 )

Step-by-step explanation:

Answer:

Step-by-step explanation:

We need to convert function to slope-intrcept form y=mx+b, where:

-0.4x + 0.05y - 1.25 = 0         {multiply both sides by 20}

-8x + y - 25 = 0                    {add (8x+25) to both sides}

y = 8x + 25     ⇒   b = 25

Therefore y-intercept of the line is (0, 25)

Answer:

1 pound of sunflower seeds will cover about 187 square feet of land

Step-by-step explanation:

To solve this problem, we will have to assume that there is a linear relationship between the net weight of the wildflower seeds and the area of land it can cover when planted.

Based on this assumption, we can find the number of square feet that a 1 pound bag will cover, by setting up a simple relationship as shown below:

if 1.5 pounds covers 280 square feet

1 pound will cover x square feet.

by cross multiplying, we have that

x = (280 X 1) / 1.5 = 186.66 square feet.

Therefore, 1 pound of sunflower seeds will cover about 187 square feet of land
