This is something you will quickly come to recognise easily however the way to work out what is the biggest change is
1.9470 - 1.8470 = 0.1
2.2199 - 2.2188 = 0.0011
3.15209 - 3.15208 = 0.00001
4.72096 - 4.72086 = 0.0001
Therefore the first one is the biggest change

The height of a triangle is 7 ft more than its base. If the area of the triangle is 30 ft2, what is the length of the base?
SSSSS [86.1K]

Answer:

see below

Step-by-step explanation:  5 27  7  16

area = 1/2 bh

height of a triangle is 7 ft more than its base

base = b

height = b + 7

area = 30

area = 1/2 b(h)

30 = 1/2 b(b + 7)

30 = 0.5(b²+ 7b)

30 = 1/2 b²+ 3.5b           solve for b

1/2 b²+ 3.5b = 30        

1/2 b²+ 3.5b - 30 = 0        

b²+ 7b - 60 = 0            factor

   (b +12)(b - 5) = 0    when b = -12 or 5     base length can't be negative

b = base = 5

area = 1/2 bh     1/2×2(9)     = 9

area = 1/2 bh     1/2×5(12)     = 60

area = 1/2 bh     1/2×9(16)     = 56

area = 1/2 bh     1/2×12(19)     = 114

the rectangular post shown at the right measures 2w-30 by w. the poster has an area of 5400 cm^2. what is The value of w ?
borishaifa [10]

Step-by-step explanation:

w(2w - 30) = 5400

2w²- 30w = 5400

2w² - 30w - 5400 = 0

(w - 60 ) ( w + 45 ) = 0

w= 60 w= - 45

only take the positive value

therefore w = 60

  • 100 ounces = 6.25 pints
  • A mile unit is equal to 1760 yards.                                                      inches =mile  * 63360                                                                                              2*63360=126720

       2 Miles = 126720 Inches

  • There are 36 inches in a yard

       3600/36= 100

       3600 inches = 100 yards

  • 1 m = 1/1000 km

       6800/1000 = 6.8

       6800 m = 6.8 km

  • 1 m = 100 cm

        15000/100=150

         15000 cm=150 m

a) Johnson ran  yard in second= 9

     1 minute = 60 second

    Johnson ran yard in one minute=  9 *60= 540 yards

b) Johnson ran  yard in second= 9

     1 hour = 60 minutes *60 second= 1200 seconds

    Johnson ran yard in one hour=  9 *1200= 10,800 yards

c) Johnson ran yard in one hour=  9 *1200= 10,800 yards

   1 mile = 1760 yards

   miles did he run in one hour= 10,800 / 1760 =6

   Johnson ran 6 mile in one hour
