Choose the set of equivalent fractions that correctly uses the LCD for these fractions: 2/9 and 5/12
Svetradugi [14.3K]

Step-by-step explanation:

the lowest common denominator (LCD) is the lowest common multiple (LCM) of the denominator numbers (the ones at the bottom of the fractions).

finding the LCM of 9 and 12 using the prime factor method :

9 = 3×3

12 = 2×2×3

the LCM is the combination of the longest chains per prime factor. which means we have 2×2 and 3×3 as longest chains for 2 and 3.

LCD = LCM = 2×2×3×3 = 36

2/9 turns into x/36 by multiplying by 4/4 :

2/9 × 4/4 = 8/36

5/12 turns into x/36 by multiplying by 3/3 :

5/12 × 3/3 = 15/36

so, the third answer option is correct.

William estimated 140 by placing the point on the number line which is true about his estimate
ziro4ka [17]

Answer:

Step-by-step explanation:

Step-by-step explanation:

Familiarize yourself with perfect squares in the neighborhood of 140:

10^2 = 100

11^2 = 121

12^2 = 144

Note that 140 is much closer to the perfect square than it is to the perfect square 121.  The value of √140 must lie closer to 12 than to 11.

Place a point on the number line about 3/4 of the way from 11 to 12.

Answer gets BRAINLIEST If q varies inversely as r, and g = 10 when r = 2.5, find the equation that connects a
vladimir1956 [14]

Answer:

D.

Step-by-step explanation:

In direct variations, we would have:

q=kr

Where <em>k</em> is some constant.

Since this is indirect variation, instead of that, we would have:

q=\frac{k}{r}

To determine the equation, find <em>k</em> by putting in the values for <em>q </em>and <em>r:</em>

<em />10=\frac{k}{2.5}\\k=2.5(10)=25<em />

Now plug this back into the variation:

q=\frac{25}{r}

The answer is D.
