∠MNL=43°
ONP is vertical to MNL
so ONP =43°
MNL+LNO=180 as linear pair
43+LNO=180
LNO=180-43=137

What inequality represents the sentence? The product of a number and 12 is no more than 15.

bulgar [2K]

So when this sign < has a line under the greater sign so this mean greater or equal

Make b the subject of this equation A = 1/2 x b x h

aalyn [17]

The equation is $b=\frac{2A}{h}$

Step-by-step explanation:

Let us revise how to make a variable subject of an equation

Write the equation and circle the variable you want to make it subject
Keep it in one side and move all other in the other side
Make the coefficient of the subject 1

∵ A = $\frac{1}{2}$ × b × h

∵ b is the subject

∴ Multiply the two sides by 2

∴ 2A = b × h

- Divide both sides by h

∴ $\frac{2A}{h}= b$

- Switch the two sides

∴ $b=\frac{2A}{h}$

The equation is $b=\frac{2A}{h}$

If a girl read 3/8 of a chapter book and another girl read 3/6 of a chapter book which girl read more pages

fredd [130]

Answer:

The girl which read 3/6 of a chapter book read more pages than the other girl.

Step-by-step explanation:

We need to compare between $\frac{3}{8} \ and \ \frac{3}{6}$

so, the denominator of both fractions should be the same number

Factor of 6 = 1 * 2 * * 3

Factor of 8 = 1 * 2 * 2 * 2

-------------------------------------------

The common denominator = 1 * 2 * 2 * 2 * 3 = 24

$\frac{3}{8} = \frac{3*3}{3*8} =\frac{9}{24} \\\frac{3}{6} = \frac{4*3}{4*6} =\frac{12}{24}$

Then compare between $\frac{9}{24} \ and \frac{12}{24} \\$

So, the fraction of the great numerator will be the great fraction

$\frac{12}{24} > \frac{9}{24}$

∴ $\frac{3}{6} > \frac{3}{8}$

==================================================

Another solution:

Convert both fractions to decimal:

3/8 = 0.375

3/6 = 0.5

0.5 > 0.375

===================================================

Third Solution:

As the numerators are equal

The fraction of least denominator is the great fraction

So, 3/6 > 3/8
