Answer:

y= 900(1.006)^p

Step-by-step explanation:

Given data

Population= 900

Rate of increase= 0.6%

Time= p years

Let the final Population be y

y= 900(1+0.006)^p

y= 900(1.006)^p

Hence the expression is y= 900(1.006)^p

Answer:

AB = 133m

Step-by-step explanation:

You can notice the ratio of AE to DE is the same as the ratio from BE to CE(3.5). We can also say angle AEB is congruent to angle DEC because they are vertical angles. Now, because of SAS similarity, you can say triangle AEB and DEC are similar. We can set up these proportions from the definition of similar triangles:

DE / AE = BE / CE = DC / AB

And we can plug in the values we have:

42 / 147 = 36 / 126 = 38 / AB

2 / 7 = 2 / 7 = 38 / AB

We can cross-multiply to get:

2AB = 7 * 38

2AB = 266

AB = 133 m

Answer:

$4

Step-by-step explanation:

Given that

total cost of 8 identical pens and 2 identical files is $32

And, the The total cost of 3 such files would be the same  as the total cost of 4 such pens

We need to find out the cost of each file

So let us assume the following things

Pens be x

File be y

Now

8x + 2y = $32 ....(1)

3y = 4x.........(2)

y =  4x÷ 3

Now put the value of y in equation 1

8x + 1.33x = 32

x = $3.55

x = $4

The cost of each file based on the given information is $4

where:

If the total cost of 8 identical pens and 2 identical files is $32, hence;

8x + 2y = 32

If the total cost of 3 such files is the same as the total cost of 4 such pens, then;

4x = 3y

From the equation

8x + 2y = 32

2(4x) + 2y = 32

2(3y) + 2y = 32

8y = 32

y = 4

Since 6=4x = 3y

4x = 3(4)

4x = 12

x= 3

Hence the cost of each file is $4

Answer:

The circumference of the circle is 75.36cm

Step-by-step explanation:

There are two ways you can solve this, one is by using the radius and multiplying it by 2 and then pi which is 3.14, and the other is to use the diameter which is the radius times 2, and the thingy gave you the diameter, and you multiply it by 3.14 which is pi

Answer:

68 degrees

Step-by-step explanation:

The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.

The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft.  Thus,

tan x = (opp side) / (adj side) = 10/4.  Using the inverse tangent function, we find that the angle in question is

arctan (10/4) = 68 degrees

Answer:

[tex]\huge\boxed{P\approx267.75m}[/tex]

Step-by-step explanation:

Look at the picture in the attachment.

x it's the quarter of  the circle with the radius r = 75m.

The formula of a circumference of a circle:

[tex]C=2\pi r[/tex]

Therefore

[tex]x=\dfrac{1}{4}\cdot2\pi r=\dfrac{1}{2}\pi r[/tex]

Substitute r = 75m:

[tex]x=\dfrac{1}{2}\pi\cdot75=37.5\pi(m)[/tex]

The PERIMETER of the shaded region:

[tex]P=2\cdot75+37.5\pi=(150+37.5\pi)m\\\\\pi\approx3.14[/tex]

substitute

[tex]P\approx150+37.5\cdot3.14=150+117.75=267.75(m)[/tex]

Answer:

arc WV = 84 degrees

Step-by-step explanation:

Here, we want to get the length of the arc wv

We can use the angle arc relationship here

From what we have here, the value of the arc wv is the product of 2 and the angle facing it

Thus, we have it that;

Arc WV = 2 * angle WXV

arc WV = 2 * 42 = 84 degrees

Answer:

112.5cm

Step-by-step explanation:

Given data

Height of bounce= 72cm

Percentage of bounce= 64%

Let the distance be x

Hence

64% of x= 72

64/100*x= 72

0.64x= 72

x= 72/0.64

x= 112.5cm

Hence the distance is 112.5cm

Step-by-step explanation:

Answer:

The measure of angle 7 is twice the measure of angle 2, then the measure of angle 7 is

angles 2 and 7 equal 180 degrees.  180 = 2x + x

180 = 3x

x = 60

angle 7 is twice x

angle 7 = 120

Step-by-step explanation:

Answer:

5. x = 18°

6. 5x = 50°, 4x= 40°

Step-by-step explanation:

5. Both the angles shown above add up to 180, due to them being supplementary, so you get the following equation:

6x + 4x = 180

which simplifies to

10x = 180

meaning x is equal to 18.

6. The angle measures of 5x and 4x add up to 90 because they are complementary angles, giving us the equation below:

5x + 4x = 90

simplifying to

9x = 90,

and resulting in

x = 10

So 5x is equal to 50 and 4x is equal to 40.

Answer:

11.06 meters

Step-by-step explanation:

Given that

The height of a regulation soccer goal is 2.4 meters

And, the distance is 10.8 meters

We need to find out the hypothesis

Here we applied the pythagoreans theorem

So,

= √ (2.4m) ^2 + (10.8 m) ^2

= √5.76 m^2 + 116.64m^2

h = 11.06 m

Hence, the hypothesis is 11.05 meters

Answer:

The grade of this sixth and (final) test would be 91.

Step-by-step explanation:

This is an arithmetic series since each time the data is increasing by the common difference of 4, and we already know a₁ which is the first term in the sequence is 71, therefore we can say:

a₁ = 71

r = 4

a₆ = the sixth term that needs to be found out

n = 6

Formula of an arithemetic series:

aₙ = a₁ + r(n - 1)

a₆ = 71 + 4(6 - 1)

a₆ = 71 + 4(5)

a₆ = 71 + 20

a₆ = 91

Hence, the grade of this sixth and (final) test would be 91.

Hope this helps!

Answer:

1/169

Step-by-step explanation:

In a standard deck of cards, there are 4 kings and 4 queens, and there is a total of 52 cards. Probability is defined by the formula the number of desirable outcomes over the total outcomes. In the first draw, we have 52 total outcomes and 4 desirable (the 4 kings) that equal the fraction 4 / 52 or 1/13. We can do the same to find the probability of picking a queen next with replacement. That would equal 1/13 as well. The two events are independent because you are drawing the cards with replacement. Using the probability of independent events, the product of the probabilities at each stage is the answer: 1/13 * 1/13 = 1/169
