Which rational number is closest to zero 45/17 90/19 63/10 171/112 85/18

9514 1404 393

Answer:

Step-by-step explanation:

The parallel lines divide each transversal proportionally.

  x/30 = 15/26

  x = 30(15/26) ≈ 17.3

__

  y/16.5 = 26/15

  y = 16.5(26/15) = 28.6

9514 1404 393

Answer:

  27

Step-by-step explanation:

Evaluating this expression according to the order of operations is a straightforward calculator problem.

  = (81 ÷ 27)³ = 3³ = 27

__

You can also use the rules of exponents to simplify this before evaluating.

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

__

  = ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27

Answer:

- 3

Step-by-step explanation:

Given

7 - 2h ( substitute h = 5 into the expression )

= 7 - 2(5)

= 7 - 10

= - 3

On evaluating the function at h = 5, we get -

f(5) = - 3.

We have a function -

f(h) = 7 - 2h

We have to find the value of f(h) at h = 5.

f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )

f(2) = Sin( [tex]\frac{\pi }{2}[/tex] )

f(2) = 1

According to the question, we have -

f(h) = 7−2ℎ

Now, evaluating the function at h = 5, we get -

f(5) = 7 - 2 x 5 = -3

Hence, on evaluating the function at h = 5, we get -

f(5) = - 3.

Answer:

10h^2

Step-by-step explanation:

i dont remember

Answer: 10h^2

Step-by-step explanation:

You’re gonna wanna combine your like terms, so…

([6h^2 + 8h^2] - 4h^2)

(14h^2 - 4h^2 = 10h^2)

So your answer would be: 10h^2

Answer:

Step-by-step explanation:

We need to find the LCM of 12 and 9.

Their LCM is:

Number of light fixtures and light bulbs is 36.

Number of packages will be:

Step-by-step explanation:

First finding LCM of 9 and 12

9 = 3 × 3

12 = 2 × 2 × 3

LCM = 3 × 2 × 2 × 3

LCM = 36

Now,

No. of light fixtures = 36/12 = 3

No. of light bulb = 48/12 = 4

Answer:

ummm I think u want the answer x= 11 1/4

Answer:

x = 45/4

Step-by-step explanation:

4(x - 5) = 25

4x - 20 = 25

4x - 20 + 20 = 25 + 20

4x = 45

4x/4 = 45/4

x = 45/4

Answer:

y = -3/4x + 14

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal of the original line.

4/3x -> -3/4x

Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].

11 = -3/4(4) + b

11 = -3 + b

14 = b

Put everything we know and solved for back into the expression.

y = -3/4x + 14

Answer:

3.25

Step-by-step explanation:

Perimeter of triangle = 3(5) = 15 cm

Perimeter of rectangle = 2(2x - 3 + 4)

Perimeter = 2(2x + 1)

Perimeter = 4x + 2

4x + 2 = 15

4x = 15 - 2

4x = 13

x = 13/4

x = 3.25

Answer:

x = 1/2

Step by step explanation:

Two numbers a and b are each greater than zero.

i.e a > 0 and b > 0

And;

[tex] \sqrt{a} \: = \: \sqrt[3]{b} [/tex]

Since the square root of a is equal to cube root of b then,

a = b = 1

[tex] {a}^{2x \: - \: 1} \: = \: b[/tex]

[tex] {1}^{2x \: - \: 1} = {1}^{0} [/tex]

2x - 1 = 0

x = 1/2

Two numbers are 'a' and 'b'.

And a > 0, b > 0

[tex]\sqrt{a}=\sqrt[3]{b}[/tex]

[tex]a^{\frac{1}{2} }=b^{\frac{1}{3}}[/tex]

[tex]a=(b)^{\frac{2}{3} }[/tex]

We have to find the value of [tex]x[/tex] if [tex]a^{2x-1}=b[/tex],

By substituting the value of [tex]a[/tex] in the given expression,

[tex](b^{\frac{2}{3}})^{2x-1}=b[/tex]

Now use the laws of exponents,

[tex]b^{\frac{2}{3}(2x-1)}=b[/tex] [Since, [tex](a^m)^n= a^{mn}[/tex]]

By comparing the exponents on both the sides,

[tex]\frac{2}{3}(2x-1)=1[/tex]

[tex]2(2x-1)=3[/tex]

[tex]4x-2=3[/tex]

[tex]4x=5[/tex]

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

[tex]x=1.25[/tex]
