Answer:

The length of the base is 340 ft and the width of the base is 135 ft

Step-by-step explanation:

Let

x -----> the length of the base

y ----> the width of the base

we know that

The perimeter of the rectangular base is

P=2(x+y)\\P=950\ ft

so

950=2(x+y) -----> equation A

x=3y-65 -----> equation B

substitute equation B in equation A  and solve for y

950=2(3y-65+y)

475=(4y-65)

4y=475+65

4y=540

y=135

Find the value of x

x=3(135)-65=340

therefore

The length of the base is 340 ft and the width of the base is 135 ft

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph. Select from the drop-down menus to correctly co
rodikova [14]

Answer

Answer

The speedometer is likely to show the speed is either 36.0 mph or 44.0 mph.        

To prove

Formula

Percentage\ error = \frac{error\times 100}{Exact\ value}

Where error = |Approx value - Exact value |

First case

As given

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph.    

Here

Percentage error = 10%

Exact value = 40 mph

error = - (Approx value - Exact value )

          = - (Approx value - 40 )

          = - Approx value + 40

Put in the formula

10 = \frac{(-Approx\ value + 40)\times 100}{40}

400 = {(-Approx\ value + 40)\times 100}

\frac{400}{100} =-Approx\ value + 40      

\4 =-Approx\ value + 40      

Thus

Approx value = 40 - 4

Approx value = 36 mph

Therefore Option (b) is correct .

Second Case

error =  (Approx value - Exact value )

          =  (Approx value - 40 )

          =  Approx value - 40

Put in the formula

10 = \frac{(Approx\ value - 40)\times 100}{40}

400 = {(Approx\ value - 40)\times 100}

\frac{400}{100} = Approx\ value - 40      

\4 = Approx\ value - 40      

Thus

Approx value = 40 + 4

Approx value = 44 mph

Therefore Option (c) is correct .

Eight times the reciprocal<br> of a number equals 4 times<br> the reciprocal of 10.
saveliy_v [14]

Answer:

8(1/x) = 4(1/10)

Step-by-step explanation:

lets say the number is x

eight times the reciprocal of a number equals 4 times the reciprocal of 10

  8       *                       1//x                            =        4    *         1/10

8/x = 4/10 ,  cross multiply

4x =8*10, divide both sides by 4

x= 80/4

x= 20
