The correct question is
<span>A certain lottery has 34 numbers. in how many different ways can 4 of the numbers be selected? (assume that order of selection is not important.)

we know that
C=n</span>!/[(n-r)!*r<span>!]
n=34
r=4
then
</span>C=34!/[(34-4)!*4!]=34*33*32*31/[4*3*2*1]=46376 

the answer is 46376

Choose the best description for the real number 35
Natalija [7]

Answer:

A) Irrational, because it is not a terminating or repeating decimal.

Step-by-step explanation:

Every time a square root results in a decimal, it will always never end, and never repeat. The square root of 35 qualifies for both of these qualities, therefore, making the answer (A). Hope this helps!

What is the value of x that will make each of the two ratios proportional?
PilotLPTM [1.2K]

Answer:

a=7, b=14

Step-by-step explanation:

a. 2/6=x/21

cross multiply=

2×21=x×6

then solve

42=6x

divide both sides by 6

x=42/6=<u>7</u>

b. 150/84=25/x

cross multiply=

84×25=150×x

then solve

2100=150x

divide both sides by 150

x=2100/150=<u>1</u><u>4</u>

Given a right triangle whose side lengths are all integer multiples of 8, how many units are in the smallest possible perimeter
leonid [27]

Answer:

96 units.

Step-by-step explanation:

Let a, b represent legs and c represent hypotenuse of the given right triangle.

We are told that in the given triangle all side lengths are all integer multiples of 8. Using Pythagoras theorem, we can represent this information in an equation as:

(8a)^2+(8b)^2=(8c)^2

64a^2+64b^2=64c^2

Upon dividing both sides by by 64, we will get:

a^2+b^2=c^2

We know that smallest Pythagoras triplet is such that a=3, b=4\text{ and }c=5.

Since all sides are multiple of 8, so the smallest possible perimeter would be 8(3+4+5)=8*12=96.

Therefore, the smallest possible perimeter of such a triangle would be 96 units.

I could use some help
jok3333 [9.3K]

Answer:

\boxed{50cm^2}

Step-by-step explanation:

Hello There!

The shown figure is a trapezoid

The formula for area of a trapezoid is

A=\frac{a+b}{2} h

where a = base 1

b = base 2

h = height

the dimensions given are

13 & 7 - bases

5 - height

so all we have to do is plug in the values into the formula

A=\frac{7+13}{2} 5\\7+13=20\\\frac{20}{2} = 10\\10*5=50\\A=50

So we can conclude that the area of the trapezoid is 50 cm²
