Express the fractions 1/2,3/16,and 7/8 with and LCD

1 answer:

3 0

<span>LCD is the least common multiple of the denominators of the fraction. The use of finding the LCD of a fraction is to simplify the adding, subtracting, dividing and multiplying the fractions. For ½, 2 is the least common denominator. For 3/16, 16 is the least common denominator. For 7/8, 8 is the least common denominator. Each of these fractions cannot be reduced to a simpler form because these are their simpler forms. If it can be reduced, the LCD would vary.</span>

What is the slope of the line that contains the points (-1, 8) and (5, -4)?

maxonik [38]

Answer:

slope = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 8) and (x₂, y₂ ) = (5, - 4)

m = $\frac{-4-8}{5+1}$ = $\frac{-12}{6}$ = - 2

A. Steve received the following test scores: 78, 83, and 79. Find Steve’s test average.

Andreyy89

Average =total sum of all the numbers / number of items in the set.

In other words, to find the average, add up all of the numbers in the set, and then divide by however many items you have.

Test scores: 78,83 and 79

average =(78+83+79)/3 = 80

weights : 2 lb, 5 lb, 7 lb, 5 lb, 9 lb, and 8 lb.

average = (2 lb+ 5 lb+ 7 lb+ 5 lb+ 9 lb+ +8 lb)/6 = 36/6 = 6lb

yawa3891 [41]

Answer:

Step-by-step explanation:

a ) The worth of Jean-Claude's gnome after 1 year

= 80000 x 1.02

= £81600

b ) common ratio of geometric progression

= 81600 / 80000

= 1.02

c ) worth after 10 years

= 80000 x 1.02¹⁰

= 80000 x 1.21899

= £97519.55

d )

120000 = 80000 x $1.02^k$

1.5 = $1.02^k$

ln1.5 = k ln 1.02

k = ln 1.5 / ln 1.02

= .4054 / .0198

= 20.47 years .
