30 + 20 + 30 + 20 = 100

30 x 10% = 3 + 30 = 33

20 x 5% = 1 + 20 = 21

33 + 21 + 33 + 21 = 108

100 / 108 = 0.925925926 = 0.93 = 93%

100% - 93% = 7%

7% increase

A flagpole casts a shadow that is 12 ft long. A 6-ft tall man casts a shadow

Vikentia [17]

Answer:

9ft

Step-by-step explanation:

Since the triangles are similar, the corresponding sides are proportional.

Let the height of the flag pole be x feet.

$\frac{x}{6} = \frac{12}{8}$

We multiply both sides by 6 to get:

$x = \frac{12}{8} \times 6$

We reduce the fraction to get:

$x = \frac{3}{2} \times 6$

We now simplify

$x = 3 \times 3$

$x = 9ft$

About 2% of the population has a particular genetic mutation. 1000 people are randomly selected. Find the mean for the number of

Alla [95]

Answer:

Step-by-step explanation:

We khow that the genetic mutation affect 2 percent of the population .

Let's try to understand what does this mean :

in a group of 100 people there is possibility of finding 2 people with this genetic mutation
in a group of 1000 the possibility raises to 20 people so we can deduce that each time we add a zero we add a zero in 2

so :

100⇒2
1000⇒20
10000⇒200
100000⇒2000

and so on

Find the missing term (x^12)^5 x (x^-2)^9 x what =(x^40)^5

Annette [7]

Answer:

$x^{158}$

Step-by-step explanation:

We are given,

$(x^{12} )^{5} \times (x^{-2} )^{9} \times y = (x^{40} )^{5}$ .

It is required to find the value of y.

Now, on simplifying above equation, we get,

$x^{60} \times x^{-18} \times y = x^{200}$

i.e. $x^{42} \times y = x^{200}$

i.e. $y = x^{200} \times x^{-42}$

i.e. $y = x^{158}$

Hence, the missing term is $x^{158}$ .
