The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the

madreJ [45]

Answer:

The numbers are 18, 13, and 72.

Step-by-step explanation:

Let the three numbers be represented by <em>a, b</em>, and <em>c</em>.

The sum of the three is 103. Thus, we can write that:

$a+b+c=103$

The second number is five less than the first. So:

$b=a-5$

And the third number is four times the first. So:

$c=4a$

Substitute:

$a+(a-5)+(4a)=103$

Solve for <em>a</em>. Combine like terms:

$6a-5=103$

Add five to both sides:

$6a=108$

And divide both sides by six. Therefore:

$a=18$

So, the first number is 18.

Since the second number is five less than the first, the second number is 13.

And since the third number is four times the first, the third number is 72.

use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet.

Use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet: TRUE

<h3>What are headlights?</h3>

A headlamp is a lamp connected to the front of a vehicle to illuminate the road ahead.
Headlamps are also commonly referred to as headlights, but in the most precise usage, the flashlight is the term for the device itself, and the headlight is the term for the beam of light produced and sold by the device.
If you are driving with your high-beam lights on, you must dim them at least 500 feet from any oncoming vehicle to avoid blinding the oncoming driver.
If you are within 200-300 feet of the vehicle you are following, you must use low-beam lights.
When visibility is less than 500 feet and there is insufficient light/adverse weather, headlights must be turned on for 1/2 hour after sunset to 1/2 hour before sunrise.

Therefore, the statement "use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet" is TRUE.

I need help on #37!!

Answer:

A) 12.1 , 12.01

B) infinitely large

Step-by-step explanation:

Give that the function f(x)=x2 describes the area of the square, f(x), in square inches, whose sides each measure x inches. If x is changing.

Using the formula

(f(a + h) - f(a))/h

as x changes from 6 inches to 6.1 inches

a = 6, h = 0.1

= [f(6.1) - f(6)]/0.1

= (6.1^2 - 6^2)/0.1

= (37.21 - 36)/0.1

= 1.21/0.1

= 12.1

and when x changes from 6 inches to 6.01 inches.

a = 6, And h = 0.01

Using the same formula

(f(a + h) - f(a))/h

= [f(6.01) - f(6)]/0.01

= (6.01^2 - 6^2)/0.01

= (36.120 - 36)/0.01

=0.1201/0.01

= 12.01

B) the instantaneous rate of change of the area with respect to x at the moment when x = 6 inches is infinitely large since h = 0

Joey has a full 40 coins consisting of only quarters and nickels if the total value is $5.00 how many of each does joey have.

Archy [21]

Q + n = 40....q = 40 - n
0.25q + 0.05n = 5

0.25(40 - n) + 0.05n = 5
10 - 0.25n + 0.05n = 5
-0.25n + 0.05n = 5 - 10
- 0.20n = -5
n = -5 / -0.20
n = 25 <=== 25 nickels

q + n = 40
q + 25 = 40
q = 40 - 25
q = 15 <== 15 quarters
