Which place value first determines which of the numbers 6.399 or 6.400 is the larger number?
kupik [55]

Comparing the numbers, it is found that the tenths value first determines which of the numbers 6.399 or 6.400 is the larger number.

The decimal numbers are 6.399 and 6.400.

  • The ones value for each is 6.
  • For the first value, the tenths digit is of 3, while for the second is of 4.

The tenths digit is the <u>first in which there is a difference</u>, hence, it determines which of the numbers 6.399 or 6.400 is the larger number.

The width of the walkaway be 4 feet.

<h3>What is Discriminant Formula?</h3>

The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equationax^{2} +bx+c=0 is D =b^{2} -4ac

If D > 0, then the equation has two real distinct roots.

If D = 0, then the equation has only one real root.

Given that: Area\; of \;walkway,\; a(w)\;= 4w^{2} + 100 w

also, area of walkaway = 464 square feet.

So, 4w^{2} + 100 w =464

     4w^{2} + 100 w -464=0

Using Discriminant method,

a=4, b=100, c=-464

w= \frac{-b\pm\sqrt{b^{2}-4ac} }{2a}

w= \frac{-100\pm\sqrt{(100)^{2}-4*4*(-464)} }{2*4}

w= \frac{-100\pm\sqrt{17424} }{8}

So, w_1= \frac{-100+\sqrt{17424} }{8} \;\;\;\; w_2= \frac{-100-\sqrt{17424} }{8}

w_1= \frac{-100+132 }{8} \;\;\;\; w_2= \frac{-100-132}{8}

w_1 = 4 \;\;\;\; and \;\;\; w_2= -29

Hence the width of the walkaway be 4 feet.

On a scale drawing 2 centimeters represent 50 meters. How many centimeters represent 5 meters?
Tanya [424]

Answer:

0.2 centimeters

Step-by-step explanation:
Strategy 1:

Make the equation: 5=a•s, where s is the scale factor and "a" is the number of centimeters which 5 meters

First, we need to find the scale factor. 50 meters would be s times greater than 2 centimeters. Find s by first converting meters into centimeters
50m=5000cm. 5000cm=2cm*s, so s = 2500
5m=a*2500, a=0.002 meters, and 0.002 meters is equal to 0.2 centimeters.

Strategy 2:
the ratio of the scale drawing to real life will always stay the same, so
2 cm / 50 meters = x / 5 meters, and cross multiply to get
x cm* 50 m = 2 cm * 5 m, so
x cm * 10 = 2 cm
x cm = 2/10 cm
x cm = 0.2 cm

Strategy 3:
Notice that 5 meters is 10 times smaller than 50 meters, so on the scale drawing, we are looking for a number 10 times smaller than 2 centimeters, so  2/10=0.2 cm
