1000cm in the ratio of 4:5:6

Answer:

option is B)

Step-by-step explanation:

2x is a perfect square. but x is not a perfect square, this brings us to the conclusion tht prob x is 2.

2x = 4

hence correct option is B) 4x is a perfect square, as 4x4=16, which is a perfect square...

PEMDAS

4 to the power of 3 is 64

100/5 = 20

20 * 4 = 80

80 + 64  = 144

Answer: 3/4x + -11

Step-by-step explanation:

3/8x -8 + 3/8x - 3

= 3/8x + - 8 + 3/8x + -3

Combine like terms

3/8x + -8 + 3/8x + -3

=(3/8x + 3/8x) + ( -8 + -3)

Answer: 3/4x + -11

Answer:

The rule for the linear function wil be:

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points

Finding the slope between (0, 0) and (1, 1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 =  [1 - 0] / [1 - 0]

                 = 1 / 1

                 = 1

Thus, the slope of the line = m = 1

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = 1 and b = 0 in the slope-intercept form of linear function

y = mx+b

y = (1)x + 0         ∵ m = 1, b = 0

y = x

f(x) = x     ∵

Therefore, the rule for the linear function wil be:

HOPE THIS HELPS IF NOT THEN SORRY

Answer:

the answer is 10

Step-by-step explanation:

the formula for distance is square root ( of the entire equation),, (x1-x2) squared +(y1-y2) squared so (-5-3)+(4-(-2)) ( both answers squared) equals -8 squared plus 6 squared and you get 64+36 which is 100 and the square root of 100 is 10. Hope that wasn't confusing

Step-by-step explanation:

2x² + 8x - 1 = 0

2(x + 2)² - 9 = 0

2(x + 2)² = 9

(x + 2)² = 4.5

x = √4.5 - 2 or x = -√4.5 - 2

x = 0.12 or x = -4.12.

Answer:

It is (9,-3) because x increased by 1 unit and y increased by 4 units.

Answer:

[tex](9,-3)[/tex]

Step-by-step explanation:

[tex](8,-7)[/tex]

If it moves right, add the value to the x-coordinate. If it moves left, subtract the value from the x-coordinate. In this case, because the point was translated 1 unit right, we add 1 to the x-coordinate 8.

[tex](9,-7)[/tex]

If it moves up, add the value to the y-coordinate. If it moves down, subtract the value from the y-coordinate. In this case, because the point was translated 4 units up, we add 4 to the y-coordinate.

[tex](9,-3)[/tex]

Answer:

36 comic books and 339 Pokemon cards

Step-by-step explanation:

Let number of comic books be [tex]x[/tex] and number of Pokemon cards be [tex]y[/tex].

Total number of comic books and Pokemon cards is [tex]375[/tex]. So we get the equation

[tex]x+y=375\\\Rightarrow y=375-x[/tex]

Cost of one comic book is $5.79 and one Pokemon card is $3.35.

They need to make $1345 so we get the equation

[tex]5.79x+3.35y=1345\\\Rightarrow 5.79x+3.35(375-x)=1345\\\Rightarrow 5.79x-3.35x+3.35\times 375=1345\\\Rightarrow x=\dfrac{1345-3.35\times 375}{5.79-3.35}\\\Rightarrow x=36.37\approx 36[/tex]

[tex]y=375-x=375-36\\\Rightarrow y=339[/tex]

So, they need to sell approximately 36 comic books and 339 Pokemon cards.

Answer:

The opposite of -10·t and t - 10·t is t

Step-by-step explanation:

1) The opposite of 4·x and -5 + 4·x is given as follows;

-4·x + (-5 + 4·x) = -4·x -5 + 4·x = -4·x + 4·x - 5 = 0 - 5 = -5

2) The opposite of -10·t and t - 10·t is given as follows;

-(-10·t) + (t - 10·t) = 10·t + t - 10·t = 10·t - 10·t + t = 0 + t = t

3) The opposite of (-7 - 4·v) and -4·v is given as follows;

-(-7 - 4·v) + (-4·v) = -1 × (-7 - 4·v) - 4·v  = 7 + 4·v - 4·v  = 7 + 0 = 7

Answer:

Answer:

y = 9.5

Step-by-step explanation:

Express the ratios in fractional form, that is

[tex]\frac{1.5}{4}[/tex] = [tex]\frac{9}{2y+5}[/tex] ( cross- multiply )

1.5(2y + 5) = 36 ( divide both sides by 1.5 )

2y + 5 = 24 ( subtract 5 from both sides )

2y = 19 ( divide both sides by 2 )

y = [tex]\frac{19}{2}[/tex] = 9.5

Answer:

the answer is 50 %

Step-by-step explanation:

C.P x (100+ (P/L) ) over 100 = S.P

C.P x 50 over 100 = 8500

C.P = 8500 x 100 over 50 = 17000 .Rs.

Step-by-step explanation:

Answer:

Is C

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sec²x = 1 + tan²x

Consider the left side

- tan²x + sec²x

= - tan²x + 1 + tan²x ← collect like terms

= 1

= right side, thus proven

Step-by-step explanation:

By rotating a figure,

The length of its sides remain the same.

Therefore line AB = line A'B'.

=> 5x - 14 = 4x + 4

=> x = 18

Hence, line AB = 5(18) - 14 = 76.

Answer:

The length of AB = 76 units.

Step-by-step explanation:

We know that Rotations, just like reflections, and translations, are termed isometric.

In other words, these transformations do not alter the size of the figure.

If the size and shape of the figure are not altered, then the figures are termed as congruent.

Given

AB = 5x-14

A'B' = 4x+14

As A'B'C'D' is obtained by rotating ABCD,

so

AB = A'B'

substituting AB = 5x-14 and A'B' = 4x+14

5x-14 = 4x+14

5x - 4x = 14+14

x = 18

Thus,

AB = 5x-14

substitute x = 18

AB = 5(18)-14

AB = 90 - 14

AB = 76

Therefore, the length of AB = 76 units.

Answer:

400 megabytes of data used will make the cost from either company equal.

Step-by-step explanation:

Given that:

Per month charges of Company A = $80

Charges of 100 MB = $5 = [tex]\frac{5}{100}=\$0.05\ per\ MB[/tex]

Let,

x be the number of MBs consumed.

y be the total charges.

y = 0.05x+80

Per month charges of Company B = $60

Charges of 100 MB = $10 = $0.1 per MB

y = 0.1x+60

For equal charges;

0.05x+80 = 0.1x + 60

80-60 = 0.1x-0.05x

20 = 0.05x

[tex]\frac{0.05x}{0.05}=\frac{20}{0.05}\\x=400[/tex]

Hence,

400 megabytes of data used will make the cost from either company equal.

Answer:

[tex]perimeter = 2(l + w) \\ but \: length = 40 \times width \\ perimeter = 2(40w + w) \\ p = 2(41w) \\ 320 = 2(41w) \\ w = \frac{320}{(2 \times 41)} \\ w = 3.902 \: yards \\ length = 40 \times w \\ = 40 \times 3.902 \\ l = 156.08 \: yards[/tex]

9514 1404 393

Answer:

Step-by-step explanation:

Let w represent the width of the field. Then the length is (w+40), and the perimeter is ...

  P = 2(L +W)

  320 = 2((w+40) +w) . . . . fill in values

  160 = 2W +40 . . . . . . . . . divide by 2, collect terms

  80 = w +20 . . . . . . . . . . .  divide by 2

  60 = w . . . . . . . . subtract 20

  w+40 = 100

The length is 100 yards; the width is 60 yards.

Answer:

The number is -43.75.

Step-by-step explanation:

4x/5 - 11 = -46

4x/5 = -35

x = -43.75

Answer:

-43.75

Step-by-step explanation:

This is the answer because:

1) We know that 4/5 of a number has to equal -35 since -46 + 11 = -35.

2) 4/5x = -35 (solve for x): -35 ÷ 4/5 = -43.75

3) 4/5 x -43.75 = -35, I got this by solving for x (look at step 2)

Therefore, the answer is -43.75

Step-by-step explanation:

(3x-2y=-16)first put in standard form y=mx+b

(-2y=-3x-16) divide both sides by -2

y=3/2x+8

Answer:

C

Step-by-step explanation:

By opposite I'm going to assume they mean the perpindicular line

To do this you first need to convert the function into linear form

So we have 3x-2y=-16

and so we can add 2y and 16 to both sides to get

3x+16=2y

then divide by 2 to get

3/2x+8=y

This is our function in linear form but now we need the opposite by taking the negative reciprocal of the slope

This means our near equation is now -2/3x+8 while none of them give that as an option directly if you simplify C it will match

Answer:

The function f(x) = -9.5 + 6 + x² is neither odd or even.

Step-by-step explanation:

We know that a function is termed as 'even' when

f(-x) = f(x) for all x

We know that a function is termed as 'odd' when

f(-x) = -f(x) for all x

Given the function

f(x) = -9.5x⁵ + 6 + x²

substitute x with -x

f(-x) = -9.5(-x)⁵ + 6 + (-x)²

as (-x)⁵ = -x⁵, so

f(-x) = -(-9.5x)⁵ + 6 + (-x)²

Apply exponent rule: (-a)ⁿ = aⁿ, if n is even

f(-x) = -(-9.5x)⁵ + 6 + x²

Apply rule: -(-a) = a

f(-x) = 9x⁵ + 6 + x²

As

f(-x) ≠ f(x) ≠ -f(x)

Therefore, the function f(x) = -9.5 + 6 + x² is neither odd or even.
