Answer:

1/2

D

Step-by-step explanation:

slope = [tex]\frac{rise}{run}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

[tex]\frac{2}{4}[/tex] = [tex]\frac{3}{6}[/tex]  Same ratio. Both reduce to [tex]\frac{1}{2}[/tex]

if QRST is indeed a quadrilateral, then, Check the picture below.

If that answer doesn't work, then try 29 without the percent sign.

============================================================

Explanation:

We know with absolute certainty that the person ordered a hot drink, due to the "given".

This means we only focus on the values in the first row.

There are 5+48+22 = 75 hot drinks ordered. Of that total, 22 hot drinks are large.

The probability of getting a large drink, given it was a hot beverage, is 22/75 = 0.2933 approximately.

This converts to 29.33% and that rounds to 29%

Answer:

[tex]\dfrac{x}{2}=25.5[/tex]

Step-by-step explanation:

Let the number be x.

Peter halves the number and gets an answer of 25.5.

It means,

Half of x equals 25.5. So,

[tex]\dfrac{1}{2}x=25.5[/tex]

or

[tex]\dfrac{x}{2}=25.5[/tex]

Hence, the required equation is [tex]\dfrac{x}{2}=25.5[/tex].

Answer:

-11/28

Step-by-step explanation:

Following BODMAS:

(2/5 * -3/7) - (1/6 * 3/2) + (1/14 * 2/5)

= (-6/35) - (1/4) + (1/35)

= 1/35 - 6/35 - 1/4

= -5/35 -1/4

= -55/140

= -11/28

Answer:

4 < k < 12

Step-by-step explanation:

The given function is y = 2·x² + k·x + 2·k - 6

Where the curve lies above the x-axis for all values of x, the function does not have a root and the discriminant, Δ, is negative, to give complex roots

∴ The discriminant Δ = k² - 4·2·(2·k - 6) < 0

k² - 4·2·(2·k - 6) = k² - 16·k + 48 < 0

(k - 12)·(k - 4) < 0

∴ k < 12 or k > 4 given that by substitution, we have;

When k = 3  < 4

k² - 16·k + 48 =  3² - 16×3 + 48 = 9 > 0

Also the product of two negative numbers is larger than 0

Therefore, the set of values of k for which the curve lies above the x-axis for all values of x is 4 < k < 12

Answer:

5 [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

The sum to n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a(1-r^{n}) }{1-r}[/tex]

where a is the first term and r the common ratio

The expression inside the summation is

4 [tex](\frac{1}{4}) ^{n-1}[/tex] ← the nth term of a geometric sequence

with a = 4 and r = [tex]\frac{1}{4}[/tex] , then

[tex]S_{4}[/tex] = [tex]\frac{4(1-(\frac{1}{4}) ^{3}) }{1-\frac{1}{4} }[/tex]

    = [tex]\frac{4(1-\frac{1}{64}) }{\frac{3}{4} }[/tex]

    = [tex]\frac{16}{3}[/tex] ( [tex]\frac{63}{64}[/tex] )

    = [tex]\frac{21}{4}[/tex]

    = 5 [tex]\frac{1}{4}[/tex]

P(R)=0.15

Answer:

p = [tex]\frac{16}{q+1}[/tex]

Step-by-step explanation:

Since there are 2 equal roots then the value of the discriminant is zero, that is

b² - 4ac = 0

Given

(q + 1)x² - 8x + p = 0 ← in standard form

with a = q + 1, b = - 8, c = p , then

(- 8)² - 4p(q + 1) = 0

64 - 4p(q + 1) = 0 ( subtract 64 from both sides )

- 4p(q + 1) = - 64 ( divide both sides by - 4 )

p(q + 1) = 16 ( divide both sides by q + 1 )

p = [tex]\frac{16}{q+1}[/tex]

Respuesta:

$ 52.5

Explicación paso a paso:

Dado

Costo de la chaqueta = $ 75

Mark off = 30%

Descuento = 30% de $ 75

Precio de descuento = 0,3 * 75

Precio de descuento = $ 22.5

Costo después de la venta = $ 75 - $ 22.5

Costo después de la venta = $ 52.5

Por lo tanto, el costo después de la venta es de $ 52.5

Step-by-step explanation:

i got it right and

Answer:

sorry only doing the ones im sure of

a)

FBC is half the circle, so the angle would = 180.

180 - 135 = 45, so thats the angle between BC

its a vertical angle, so it would be the same on the other side, between FE

the only angle left is betweeen DC, so add them all up and minus by 360

360 - 306 = 54

b)

a triangle's angles add up to 180, so

49 + 70 = 119

180 - 119 = 61

since this is an inscribed angle that isnt connected to the center, the arc will be double the angle

so ? = 122

d)

5(8) = 40

40/4 = 10

x = 10

f)

the rest of the circle is 243 bc 360-117=243

243 - 177 = 126

126/2 = 63

Answer:

12376 huevos

Step-by-step explanation:

Son 68 gallinas en 26 corrales por tanta se multiplicaría

26 x 68=1768 estas serian el total de las gallinas en todos los corrales, aparte te dicen que cada pone un huevo al día, entonces como te piden cuantos huevos serán en 7 días sería:

1768 x 7= 12376

1768= a los huevos de cada gallina en un día ya que te dice que cada una pone un huevo en cada día.

Answer:

A = 90.25 pi in^2

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

19pi = 2*pi*r

Divide each side by 2 pi

19pi / 2 pi = 2*pi*r/ 2pi

9.5 = r

The area is given by

A = pi r^2

A = pi ( 9.5)^2

A = 90.25 pi in^2

Answer:

The area of circle is 90.25 π inches².

Step-by-step explanation:

Given :-

Circumference of circle is 19 π in.

To Find :-

Area of circle

Solution :-

Firstly, we need to find radius of circle

Using formula

Circumference of circle = 2 π r

substitute the value

19 π inches = 2 π r

Divide each side by 2 π

19 π inches / 2 π = 2 π r / 2 π

9.5 inches = r

Now, Finding the area of circle

Using formula

Area of circle = π × r²

Where,

Substitute the values

Area of circle = π × ( 9.5 inches)²

Evaluate the exponent

Area of circle = π × 90.25 inches ²

multiply ,we get

Area of circle = 90.25 inches²

Hence, the area of circle is 90.25 π inches².
