Answer: 45.168

Step-by-step explanation:  First find 941 x 48 = 45168 then put the decimal point at the thrid digit as the decimal in 9.41 is in the 2nd digit and 1st in 4.8 so 2 + 1 = 3 so the answer is 45.168

Answer:

3x

Step-by-step explanation:

Since k(x)=27x^3, we replace it in h( k(x) ), we will get:

h(27x^3)

Given that h(x)={3}√x [my keyboard doesn't support cubic root]

= {3}√(27x^3)

27 is 3^3,

Simplifying, the final answer is:

3x.

Answer:

3x

Step-by-step explanation:

[tex]h(x) = \sqrt[3]{x},\: \: k(x) = 27 {x}^{3} \\ \\ (a) \: h(k(x)) = \sqrt[3]{27 {x}^{3} } \\ \\ = \sqrt[3]{ {(3x)}^{3} } \\ \\ = {(3x)}^{3 \times \frac{1}{3} } \\ \\ = 3x[/tex]

There are nine pink sections and 11 sections total. The probability of landing on a pink section is 9/11.

Multiply the probability by 55

[tex]\frac{9}{11}[/tex] × [tex]\frac{55}{1}[/tex]

Cancel the 11 and 55. The 11 becomes a 1 and 55 becomes a 5

Step-by-step explanation:

Area of parallelogram = bh
=> The height = 108 : 9 = 12 ft

The length of the rug is less than the height of the parallelogram : 10 < 12
The width of the rug is also less than the base of the parallelogram : 6 < 9

So, the rug will fit in the room

Factors of a polynomial can divide it without leaving remainder. The other factor of [tex]6x^2 - 7x + 2[/tex] is given by Option D :  [tex]3x + 2[/tex]

Let the  polynomial A(x) has one factor f(x).

Then, it means, we have:

[tex]\dfrac{A(x)}{f(x)} = g(x)[/tex]

Thus, A(x) can be written as [tex]A(x) = f(x) \times g(x)[/tex]

Thus, the other factor of that polynomial is

[tex]g(x) = \dfrac{A(x)}{f(x)}[/tex]

For given case, the polynomial [tex]A(x)[/tex] is

[tex]A(x) = 6x^2 - 7x + 2[/tex]

Its one factor f(x) is given [tex]f(x) = 2x - 1[/tex]

Thus, its second factor is obtained as:

[tex]g(x) = \dfrac{A(x)}{f(x)} = \dfrac{6x^2 - 7x + 2}{(2x - 1)} = \dfrac{6x^2 -4x -3x - 2}{2x - 1}\\\\g(x) = \dfrac{2x(3x + 2) - 1(3x + 2)}{2x - 1} = \dfrac{(2x - 1)(3x + 2)}{2x - 1}\\\\g(x) = (3x + 2)[/tex]

Thus, the second factor of the given polynomial is

Option D :  [tex]3x + 2[/tex]

Answer:

  8. parallel

  9. not parallel

Step-by-step explanation:

Segment ST will be parallel to base segment PR if the sides of the triangle are divided proportionally.

We can compare the whole to the short part:

  102/45 ?? (41.8 +33)/33

  2.266... = 74.8/33 = 2.266...

The sides are proportional, so the segments are parallel.

__

We can compare the longer portion to the shorter portion.

  38/19 ?? 52/24

  2 ≠ 2 1/6

The sides are not proportional, so the segments are not parallel.

_____

Additional comment

Here, we compared segment lengths on the same side of the triangle. You can also compare segment lengths on opposite sides of the triangle. For example, in 9, you could look at any of the relations ...

  19/24 vs 38/52

  19/(19+38) vs 24/(24+52)

or the inverse of these:

Answer:

25 students

Step-by-step explanation:

Let x represent the amount of students in the astronomy club then:

80%x=20

Convert 80% to a fraction. Any percentage is that number over 100:

[tex]\frac{80}{100}x=20[/tex]

Simplify the fraction:

[tex]\frac{8}{10}x=20[/tex]

[tex]\frac{4}{5}x=20[/tex]

Multiply both sides by 5:

[tex]4x=100[/tex]

Divide both sides by 4:

[tex]x=25[/tex]

There are 25 students in the astronomy club.

Step-by-step explanation:

the introduction of a fraction tells us that we are dealing with multiplications, and therefore a geometric sequence (where every new term is created by multiplying the previous term by a constant factor, the ratio r).

I think your teacher made a mistake, or you made one when typing the question in here.

there is no factor r that creates

15×r = 9

and

9×r = 5/27

it would mean that

15 × r² = 5/27

r² = 5/27 / 15 = 5/27 × 1/15 = 5/405 = 1/81

r = 1/9

but 15 × 1/9 = 5 × 1/3 = 5/3 is NOT 9

and 9 × 1/9 = 9/9 = 1 is NOT 5/27

so, this can't be right.

on the other hand

15 × r = 9

r = 9/15 = 3/5

and then

9 × 3/5 = 27/5

so, either the sequence should have been

15, 5/3, 5/27

or (and I suspect this to be true)

15, 9, 27/5

under that assumption we have

s1 = 15

r = 3/5

sn = sn-1 × r = s1 × r^(n-1) = 15 × (3/5)^(n-1)

s10 = 15 × (3/5)⁹ = 15 × 19683/1953125 =

= 3 × 19683/390625 = 59049/390625 =

= 0.15116544 ≈ 0.151

Answer:

  B.  97.2

Step-by-step explanation:

The sequence of positive terms is ...

  54, 24, 10 2/3, 4 20/27, ...

This sequence has first term 54 and common ratio 24/54 = 4/9. The sum of the infinite series is ...

  S = a1/(1 -r) = 54/(1 -4/9) = 54(9/5)

  S = 97.2

The sum of the positive terms in the infinite series is 97.2.

  = a(3a² -2a +4) -6(3a² -2a +4)

1. Lenas total pay if she sells 25 copy is $3050.

2. The copy sold is 34.

From the information given, Lena is a software salesperson. Her base salary is $1800 and she makes $50 more for every copy of English is Fun she sells.

It should be noted that the total pay, P after selling c copies is given by:

P = 50c + 1800

c = number of copies

The pay for 25 copies will be:

P = 50c + 1800

P = 50(25) + 1800

P = 1250 + 1800

P = 3050

When lenas total pay is 3500 the copys did she sell will be:

50x + 1800 = 3500

Collect like terms

50x = 3500 - 1800

50x = 1700

Divide

x = 34

The copy is 34.
