How to turn a fraction with whole numbers to a decimal form

1 answer:

4 0

A mixed number<span> such as 7 1/4 can be converted to a </span>decimal<span>. It is implied that 7 1/4 is really 7 + 1/4 and that 7 = 7/1 therefore we are first adding the fraction 7/1 + 1/4. Since 4 is the denominator original fraction part we will use it as our common denominator. 7/1 * 4/4 = 28/4. Hope this helps</span>

Can any kind soul help me please

Answer:

p-q= -4

p=q-4

x^2 + px + q=0

=> x^2 + (q-4)x + q = 0

d= b^2-4ac

=(q-4)^2 - 4(1)(q)

= q^2 + 16 -8q - 4q

=q^2 -12q+16

given that D=16

q^2 -12q+16 = 16

=> q^2 -12q = 0

=> q^2 = 12q

=> q = 12q/q

=> q= 12

Therefore the value of q is 12 and the value of p is q-4 = 12-4= 8

A retail shop accepts only cash or checks suppose that 45% of its customers carry cash 44% carry checks and 31% carry both cash

sergejj [24]

Answer:

Step-by-step explanation:

The number of customers carrying cash=45% = 0.45

The number of customers carrying checks= 44% =0.44

The number of customers carrying both = 31% = 0.31

So,

To find the probability we will write the expression:

cash+checks-cash or checks(both)=cash and checks

0.45+0.44-both=0.31

0.45+0.44-0.31=both

0.58=both....

If x and y are adjacent angles, then x and y are ______ acute.

Anastasy [175]

Answer:

sometimes

Step-by-step explanation:

adjacent angles are two angles that share a vertex, common side/ray between them, and do not overlap.

only supplementary adjacent angles always add up to 180 degrees,

both x or y could be any angle, as long as they're sharing a common side and vertex.

drako found an emarald in a cave at a depth between negative 1\2 and negative 1 2\3 meters. Which number could represent the dep

Delvig [45]

Answer:

$(-\frac{7}{6} )$

Step-by-step explanation:

From the question the emerald was located at a depth which is between -1/2 and -1 2/3 meters

This statement can be written as

$(-1\frac{2}{3}) -(-\frac{1}{2} )$

To get the depth, you find the depth of the emerald location, you find difference between the two mentioned depths

$-(1\frac{2}{3} )-(-\frac{1}{2} )\\\\$

Change first term to improper fraction

$=-(\frac{5}{3} )-(-\frac{1}{2} )\\\\$

Find the LCM to solve the operation the involves the fractions.The Least common multiple here is 6 i.e 3*2

$=(-\frac{5}{3} )-(-\frac{1}{2})\\$

$=\frac{-5}{3} +\frac{1}{2} =\frac{-10+3}{6} =\frac{-7}{6}$

The number that could represent the depth at which the emerald was located is

$=\frac{-7}{6}$
