Rational numbers are numbers that have an ending to them or repeat themselves, such as 0.675 or 0. $\overline {66}$ . Irrational numbers are numbers that have no ending and don't repeat themselves, such as pi.

____________________________________________________________

1) m = 2/3 = 0. $\overline {66}$ , n = √9 = 3

so 1 cannot be a choice.

2) m = 6/5 = 1.2, n = √2 = 1.41421356237...

so 2 can be a choice.

3) m = 4 $\pi$ = 12.5663706..., n = √5 = 2.2360679775...

so 3 cannot be a choice.

4) m = 6/2 = 3 (whole number, not rational), n = $\pi /2$ = 1.57079633...

so 4 cannot be a choice.

6/5 is equal to 1.2, so that is a rational number.

√2 is equal to 1.570796326794 ... which is a irrational number.

so ur answer would be the top right answer choice.

hope i helped:)

A hardware supplier manufacturers 3 kinds of clamps types AB &c production restrictions force it to make 10 more type C clam

hichkok12 [17]

Answer:

Hardware supplier will manufacture 60 Type A clamps, 180 Type B clamps and 150 Type C clamps.

Step-by-step explanation:

Given:

Company produces 3 types of clamp

Type A

Type B

Type C

production restrictions force it to make 10 more type C clamps in the total of the other types

Hence We can say that Clamp C is equal to sum of Clamp A and Clamp and 10

framing in equation form we get;

$C=A+B+10 \ \ \ \ \ equation \ 1$

Also Given:

3 times as many Type B clamps as type A clamps

Hence we can say that Clamp B is equal to thrice of Clamp A.

$B=3A \ \ \ \ equation\ 2$

Also Given

Total Number of Clamps = 490

Hence Total Number of Clamps is equal to sum of number of Clamps of Type A, Type B and Type C.

Framing in equation form we get;

$A+B+C =490 \ \ \ \ equation \ 3$

Substituting the equation 1 and Equation 2 in equation 3 we get

$A+B+C=490\\\\A+3A+A+B+10=490\\\\A+3A+A+3A+10=490\\\\8A = 490-10\\\\8A=480\\\\A=\frac{480}{8}=60$

Now Substituting the Value of A in equation 2 we get;

$B=3A = 3\times60 =180$

Now Substituting the values of A and B in equation 1 we get:

$C=A+B+10 = 60+180+10= 250$

Now checking the same we get;

$A+B+C=490\\60+180+250=490\\490=490$

Hence the Hardware supplier will manufacture 60 Type A clamps, 180 Type B clamps and 150 Type C clamps.

You are planning to purchase ten pencils of type A which cost a total of $14.00 and five pencils of type B which cost $15.00. A)

muminat

Answer:

A.1 type A pencil costs $1.40. 1 type B pencil costs $3.00.

B. Type A pencils are a better buy.

Step-by-step explanation:

A.14.0 divided by 10 is 1.4. 15.0 divided by 5 is 3.

B. 10 type b pencils cost $30.00. 10 type a pencils cost less, only $14.00, so it is a better buy. Hope this helped!

The diagram below shows the graph of the quadratic function f (x) = ax² + 8x + c. calculate the value for each of the following.

Alexxandr [17]

Answer:

see explanation

Step-by-step explanation:

The y- intercept is at (0, 6) ⇒ c = 6

The x- coordinate of the vertex is at the midpoint of the zeros, that is

m = $\frac{-3-1}{2}$ = $\frac{-4}{2}$ = - 2

Since the zeros are x = - 3 and x = - 1 then the factors are (x + 3), (x + 1) and

f(x) = a(x + 3)(x + 1) = a(x² + 4x + 3)

Comparing with f(x) = ax² + 8x + 6 ⇒ a = 2

Thus

f(x) = 2x² + 8x + 6

Substitute m = - 2 into the equation for value of n

n = 2(- 2)² + 8(- 2) + 6 = 8 - 16 + 6 = - 2

Hence

c = 6, m = - 2, a = 2, n = - 2
