Step-by-step explanation:

Answer: 228 in3 (sorry I don’t know how to do the mini number at the top)

Answer:

Step-by-step explanation:

Let the angles size = x

The complement of the angle is 90 - x

Two times the compliment is 2*(90 - x)

Three times the angle is 3x

25 less than 3 times the angle = 3x - 25

Now you have to equate the two bolded pieces of information.

3x - 25 = 2(90 - x)                 Remove the brackets

3x - 25 = 180 - 2x                 Add 25 to both sides

     25      25

3x = 205 - 2x                         Add 2x to both sides.

2x              2x

5x = 205                                Divide by 5

5x/5 = 205/5

x = 41

The compliment of x = 90 - 41 = 49

The angle itself = 41

Answer:

m<ACB  = 59degrees

Step-by-step explanation:

To get <ACB, first we need arcAB

arcAB + arcAC + arcBC = 360

arcAB + 89 + 153 = 360

arcAB+242 = 360

arcAB = 360 - 242

arcAB = 118

Also, m<ACB = 1/2arcAB

m<ACB = 1/2*118

m<ACB  = 59degrees

Answer:

Circumference of circle = (15.5)π cm

Step-by-step explanation:

Missing information:

Area of circle = 60π cm²

Find:

Circumference of circle

Computation:

Area of circle = πr²

Area of given circle = π(Radius of circle)²

60π = πr²

60 = r²

Radius of circle = 7.75 cm  (Approx)

Circumference of circle = 2πr

Circumference of circle = 2(π)(7.75)

Circumference of circle = (15.5)π cm

Answer:

Step-by-step explanation:

Let original population be, P = x

Growth in 12 years, A = 2x

Rate be = r

Time = 12years

Find the rate :

   [tex]A = P(1 + \frac{r}{100})^t[/tex]

 [tex]2x = x(1 + \frac{r}{100})^{12}\\\\\frac{2x}{x} =(1 + \frac{r}{100})^{12}\\\\2 = (1 + \frac{r}{100})^{12}\\\\ \sqrt[12]{2} = (1 + \frac{r}{100})\\\\\sqrt[12]{2} - 1 = \frac{r}{100}\\\\2^{0.08} - 1 = \frac{r}{100}\\\\1.057 - 1 = \frac{r}{100}\\\\0.057 \times 100 = r\\\\r = 5.7 \%[/tex]

The annual rate of increase of the population of this city is approximately 5.78.

Find  time in which the population becomes 3 times.

That is A = 3x

P = x

R= 5.78%

               [tex]A = P( 1 + \frac{r}{100})^t\\\\3x = x ( 1 + \frac{5.78}{100})^t\\\\3 = (1.0578)^t\\\\log \ 3 = t \times log \ 1.0578 \\\\t = \frac{log \ 3}{ log \ 1.0578 }\\\\t = 19.55[/tex]

The population will grow to three times its current size in approximately 19years .

5.78% ,19 years are the answers.

2=(1+r)^12

r=(2)^(1÷12)−1

R=0.0578*100=5.78%

3=(1+0.0595)^t

t=log(3)÷log(1.0595)

t=19 years

Exponential growth and exponential decay are two of the most common uses of exponential functions. Systems with exponential growth follow a model of the form y = y0ekt. In exponential growth, the growth rate is proportional to the amount present. In other words, for y'= ky

exponential function, multiply a by x to produce y. The exponential graph looks like a curve that starts with a very flat slope and becomes steep over time.

The exponential model, like the sphere model, starts at the origin and operates linearly near it. However, the increasing slope of the curve is less than the slope of the spherical model.

Given:

In the given figure the vertices of triangle ABC are A(-2,2), B(4,2), C(-2,-2).

The vertices of triangle A'B'C' are A'(-4,4), B'(8,4), C'(-4,-4).

To find:

The center of dilation and the scale factor.

Solution:

In the given graph, draw the lines AA', BB' and CC'. The intersection point of these lines is the center of dilation.

From the below graph, it is clear that the lines AA', BB' and CC' intersect each other at (0,0).

Therefore, the center of dilation is (0,0).

If a figure is dilated by factor k and the center of dilation is origin, then

[tex](x,y)\to (kx,ky)[/tex]

[tex]A(-2,2)\to A'(k(-2),k(2))[/tex]

[tex]A(-2,2)\to A'(-2k,2k)[/tex]

It is given that A'(-4,4). So,

[tex](-2k,2k)=(-4,4)[/tex]

On comparing both sides, we get

[tex]-2k=-4[/tex]

[tex]2k=4[/tex]

[tex]k=\dfrac{4}{2}[/tex]

[tex]k=2[/tex]

Therefore, the scale factor is 2.

every angle in a triangle equals 180° and every straight line equals 180°. So you just take the angles given in each triangle and subtract from 180° to get the total of the 3rd angle.

Answer:

Alternate Interior Angles

Step-by-step explanation:

Angles can be corresponding; alternate or same side; or interior or exterior. The angles 2 and 8 are on opposite sides of the transversal; this means that they must be alternate angles. Additionally, they are both within the parallel lines, so they are interior. Alternate interior angles are always congruent. Therefore, their measurements must be equal.

Answer:

They are alternate interior angles

Step-by-step explanation:

<2 and <8 are inside the parallel lines and on opposite sides of the transversal

They are alternate interior angles

Step-by-step explanation:

for san francisco earthquake:

[tex]\log(\frac{a_1}{T}) + B = 7.8\\\\\log(\frac{a_1}{T})+\log(10^{B}) = 7.8\\\\\log(\frac{a_1}{T} \times 10^{B})=7.8\\\\(\frac{a_1}{T} \times 10^B=10^{7.8}...............(i)[/tex]

similarly , for coloumbia earthquake:

divide equation (i) and (ii):

Given : GH bisects ∠FGI

It means : ∠FGH and ∠HGI are equal

Given :

∠FGH = (5x - 8)°

∠HGI = (6x - 15)°

⇒  5x - 8 = 6x - 15

⇒  6x - 5x = 15 - 8

⇒  x = 7°

Substituting the value of x, We get :

∠FGH = 5(7) - 8 = (35 - 8) = 27°

∠HGI = 6(7) - 15 = (42 - 15) = 27°

∠FGI = ∠FGH + ∠HGI = (27 + 27) = 54°

[tex]33.5\:\mathrm{ft^3}[/tex]

Step-by-step explanation:

The volume of a cone is given by [tex]V=\frac{1}{3}\cdot r^2\pi\cdot h[/tex], where [tex]r[/tex] is the radius of the cone and [tex]h[/tex] is its height.

What we're given:

Solving, we get:

[tex]V=\frac{1}{3}\cdot 2^2\pi\cdot 8\approx\boxed{33.5}[/tex]

Answer:

The volume of cone is 33.5ft ³.

Step-by-step explanation:

Using Formula,

Volume of cone = 1/3 × π × r ² × h

Where, r is the radius and h is the height of the cone.

Radius of cone, r = 2 ft

Height of cone , h = 8 ft

substitute the values into the formula

Volume of cone = 1/3 × 3.14 × ( 2ft ) ² × 8ft

Volume of cone = 1/3 = 3.14 × 4 ft ²× 8ft

multiply

Volume of cone = 1/3 × 100.8 ft ³

divide, we get

Volume of cone = 33.50 ft ³.

Therefore,the volume of cone is 33.50 ft³.

Then 8 out 12 are not blue.

8 out of 12 is the same as the fraction 8/12 which can be reduced to 2/3.

2/3 of the birds are not blue.

Answer:

y = -0.7

Step-by-step explanation:

Reorder the terms:

-2.7 + y = -2.0 + 2y

Solving

-2.7 + y = -2.0 + 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

-2.7 + y + -2y = -2.0 + 2y + -2y

Combine like terms: y + -2y = -1y

-2.7 + -1y = -2.0 + 2y + -2y

Combine like terms: 2y + -2y = 0

-2.7 + -1y = -2.0 + 0

-2.7 + -1y = -2.0

Add '2.7' to each side of the equation.

-2.7 + 2.7 + -1y = -2.0 + 2.7

Combine like terms: -2.7 + 2.7 = 0.0

0.0 + -1y = -2.0 + 2.7

-1y = -2.0 + 2.7

Combine like terms: -2.0 + 2.7 = 0.7

-1y = 0.7

Divide each side by '-1'.

y = -0.7

Simplifying

y = -0.7
