Lets write this out:-

\frac{50}{100} + \frac{30}{100}

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples. 

\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}

Now lets simplify \frac{80}{100}.

\frac{80/20}{100/20}=  \frac{4}{5}

So, \frac{50}{100}+  \frac{30}{100} = \frac{80}{100}= \frac{4}{5}

Hope I helped ya!! xD

\frac{50}{100} + [tex] \frac{30}{100}[\tex]. Just multiply the numerators. The denominator is already a common denominator.

Suppose it is known that the individual lost more than 12 pounds in a month. Find the probability that he lost less than 19 poun
telo118 [61]

The probability that he lost less than 19 pounds is 7 / 9.

According to statement

The weight loss by individual is 12 Pounds

So, by uniform distribution probability

P(c ≤ x ≤ d) = (d - c) / (b - a)

Substitute the values in it then

P(12 ≤ x ≤ 19) = (19 - 12) / (20 - 11)

P(12 ≤ x ≤ 19) = 7 / 9

So, the probability that he lost less than 19 pounds is 7 / 9.

Find the value of x. 7, 8, and 9 please!
natima [27]

Answer:

7) x= 5, 8) x= 6, 9) x= 7

Step-by-step explanation:

As per the secant theoram, if two secant intersect outside the circle then the product of the exterior secant and total length of each secant are equal.

7) ∴ (x+3)\times 3= (10+2)\times 2

opening parethesis and distributing 3 with x and 3.

⇒ 3x+9=24

subtracting 9 on both side.

⇒ 3x=15

cross multiplying

∴ x= 5.

8) (3+5)\times 5= (x+4)\times 4

Opening parethesis and distributing 4 with x and 4.

⇒ 8\times 5=4x+16

⇒ 40=4x+16

subtracting 16 on both side.

⇒ 24=4x

cross multiplying

∴ x= 6.

9) (x+5)\times 5= (6+4)\times 6

opening parethesis and distributing 5 with x and 5.

⇒ 5x+25=60

subtracting 25 on both side.

⇒ 3x=35

cross multiplying

∴ x= 7.

a gym has 275 members 40% are bronze members 28% are silver members the rest are good work out the gold members
statuscvo [17]
STEP 1:
Find % of gold members. Subtract the known % of bronze and silver members from 100%.

x= percent of gold members

x= 100% - (40% +28%)
x= 100% - 68%
x= 32% percent of gold members


STEP 2:
Find number of gold members. Multiply % of gold members by the total numbers of members (275).

x= # of gold members

x= 275 * 32%
x= 275 * 0.32
x= 88 gold members

Hope this helps! :)
