Solve for a in the proportion.

Answer:

34.2508% decrease

Step-by-step explanation:

Percent decrease = 100 x (starting value-new value/starting value)

100 x ((3.27 - 2.15)/3.27)

Answer:

$1.12

Step-by-step explanation:

$3.27-$2.15=$1.12

$1.12 + $2.15= $3.27

Answer:

-1/10

Step-by-step explanation:

Answer:

-1/10

Step-by-step explanation:

First you need a common demonator of 10

so

-1/2 --> -5/10

and  -2/5 --> -4/10

using this the equation is:

-5/10 - (-4/10) which equals

-5/10 + 4/10= -1/10

Answer:

The correction is  D

Step-by-step explanation:

From the question we are told that

    The maximum height is  [tex]h_m = 18 ft[/tex]

    The minimum height is [tex]h_i = 4 ft[/tex]

     The function that models the height of the blade is [tex]h(x) =- 14 sin(x) + 18[/tex] here x is time in seconds

 Now at maximum height

       [tex]18 = - 14 sin(x) + 18[/tex]

=>     [tex]-14 sin(x) =0[/tex]

=>     [tex]sin(x) =0[/tex]        

=>     [tex]x =sin^{-1}[0][/tex]

=>     [tex]x =0 \ s[/tex]    

 Now at minimum  height

        [tex]4 = -14 sin(x) + 18[/tex]

=>      [tex]-14 = -14 sin(x)[/tex]

=>     [tex]sin (x) = 1[/tex]

=>     [tex](x) = sin^{-1}[1][/tex]

=>     [tex]x = 1.6 \ s[/tex]

Now this values is the time taken to move from the higher position of the blade to the lower position of the blade

Now it will take this same amount of time to complete the circle

So the total time take is

    [tex]x_t = 2 * |x|[/tex]

=>   [tex]x_t = 2 * 1.6[/tex]

=>   [tex]x_t = 3.2 \ s[/tex]

Step-by-step explanation:

Answer:

rate =  92.6 miles/hours

Step-by-step explanation:

Here rate means speed

formula for speed = distance/time

since distance here is 25 miles

and time taken is 0.27 hours

thus,

speed = distance to be traveled/time in which this distance is covered

speed = 25 miles/ 0.27 hours = 92.6 miles/hours

thus, rate should be  92.6 miles/hours to make the appointment in time.

Step-by-step explanation:

Angle 4 and angle 5 are interior angles on the same side of transversal , which means the sum of angle 4 and angle 5 will be equal to 180° .

For each tank just divide the number of L by the number of fish to get the volume or fish.

For tank A it is 40/5=8, for tank B it is 100/12=8.3, and for tank C it is 180/23=7.8.

If you number them least to greatest, it is (tank C, tank A, tank B)

f(4) = 0

Step-by-step explanation:

f(4) means what is the value of y when x = 4

Now x = 4 is on the x- axis, where y = 0, thus

f(4) = 0

Step-by-step explanation:

Answer:

I would say about 13 minutes.

Step-by-step explanation:

9 4/5 KPH is about 6.1224489795918 Kilometers per minute

Multiply by 2 1/5 KPM

6.1224489795918 x 2 1/5 = 13.4693877551 Minutes

Answer: 13.469 or about 13.5 minutes

Step-by-step explanation:

Estimating part:

The first number can be rounded to 10, and second number to 2

You can set up a proportional equation

[tex]\frac{10 kilometers}{60 minutes} = \frac{2 kilometers}{x}[/tex]

then cross multiply to get 10x=120, then divide to get x = 12 minutes

Exact answer:

I like making fractions into decimals to make it easier to see

The first number as a decimal is 9.8, and the second is 2.2

Set up another proportional equation

[tex]\frac{9.8 kilometers}{60 minutes} = \frac{2.2 kilometers}{x}[/tex]

cross multiply to get 9.8x = 132

divide by 9.8 on both sides to get x = 13.5 minutes

Answer:

1/5

Step-by-step explanation:

Answer:

200

Step-by-step explanation:

Change 8 hours to minutes so the units are the same.  8(60) = 480.  Using a proportion the equation is 5/12 = j/480.  [jumps/minutes]  To solve the equation, cross multiply:  12j = 5(480) ; 12j = 2400;  j = 2400/12;  j = 200.

Given:

Anna is three years older than Matthias.

Miss Smith is four times as old as Anna.

Mr Smith is five years older than his wife.

Together they are 72 years.

To find:

The age of each family member.

Solution:

Let age of Matthias be x years.

Anna is three years older than Matthias.

Anna's age = x+3

Miss Smith is four times as old as Anna.

Miss Smith's age = 4(x+3)

Mr Smith is five years older than his wife Mrs Smith.

Mr Smith's age = 4(x+3)+5

Together they are 72 years.

[tex]x+(x+3)+4(x+3)+[4(x+3)+5]=72[/tex]

[tex]x+x+3+4x+12+4x+12+5=72[/tex]

[tex]10x+32=72[/tex]

Subtract 32 from both sides.

[tex]10x=72-32[/tex]

[tex]10x=40[/tex]

Divide both sides by 10.

[tex]x=4[/tex]

Now,

Matthias's age = 4 years

Anna's age = 4+3

                  =  7 years

Miss Smith's age = 4(4+3)

                           = 4(7)

                           = 28 years

Mr. Smith's age = 4(4+3)+ 5

                          = 28+5

                          = 33 years

Therefore, the ages of Matthias, Anna, Miss Smith and Mr Smith are 4, 7, 28 and 33 respectively.

The measure of the indicated angle θ is approximately 39.9°.

Use the concept of a triangle defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

After labeling the figure

In triangle ABC

Sin θ = AC/AB

Sin 26° = AC/19

AC ≈ 0.44 x 19

AC ≈ 8.36

Now in Triangle ADC,

tan θ = (opposite side of θ)/(Adjacent side)

tan θ ≈ 7/8.36

tan θ ≈ 0.837

Take the inverse of tan on both sides, we get,

θ ≈ 39.9°

Hence,

The value of angle θ is approximately 39.9°.

Step-by-step explanation:

Answer:

$11.67

Step-by-step explanation:

Answer:

X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
