Option 2

Step-by-step explanation:

it easy Add them all up and then you get 47/16 then divide them and convert it to mixed number and then you get 2 15/16

Answer:

2 15/16

Step-by-step explanation:

We need to make sure all fractions have the same denominator.

The LCM (least common denominator) is 16.

Now we have to multiply each nunber except 2 1/16 to get a numerator of 16.

1/2: 1x8= 8, 2x8= 16→ 8/16

3/8: 3x2= 6, 8x2= 16→ 6/16

Now every add everything all up.

8/16 + 6/16 + 2 1/16 = 2 15/16

2 15/16 is our answer.

Answer:

1 hour

Step-by-step explanation:

It would take that long because they work together, at 4 hours Ryan's 3 are subtracted and the result would be 1 hour. This is because while one of us makes the errors in the first or second paragraph, the other is checking the next and thus they finish faster.

If they worked together they can finish the given task in [tex]\frac{7}{12}[/tex] hours.

Given that, Leeson can proofread a newspaper copy in 4 hours. If Ryan proofreads the same newspaper copy, it takes 3 hours.

We need to find how long would it take if they worked together.

Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.

Now, the work done by Leeson [tex]=\frac{1}{4}[/tex] and the work done by Ryan [tex]=\frac{1}{3}[/tex]

So, work done by both together [tex]=\frac{1}{4}+\frac{1}{3}=\frac{3+4}{12}=\frac{7}{12}[/tex] hours.

Therefore, if they worked together they can finish the given task in [tex]\frac{7}{12}[/tex] hours.

Answer:

The distance from the ship to the dock is approximately 5.24 miles

Step-by-step explanation:

From the parameters given in the question, we have;

The angle formed between the dock and the lighthouse = 70°

The angle formed between the dock and the lighthouse at the ship = 80°

The distance between dock and the lighthouse = 5 miles (From a similar question online)

By sine rule, we have;

[tex]\dfrac{a}{sin(A)} = \dfrac{b}{sin(B)} = \dfrac{c}{sin(C)}[/tex]

Therefore, we have;

[tex]\dfrac{5}{sin(70^{\circ})} = \dfrac{The \ distance \ from \ the \ ship \ to \ the \ dock}{sin(80^{\circ})}[/tex]

[tex]\therefore The \ distance \ from \ the \ ship \ to \ the \ dock = sin(80^{\circ}) \times \dfrac{5}{sin(70^{\circ})}[/tex]

[tex]sin(80^{\circ}) \times \dfrac{5}{sin(70^{\circ})} \approx 5.24 \ mi[/tex]

Therefore;

The distance from the ship to the dock ≈ 5.24 miles

Answer:

£4113.70

Step-by-step explanation:

Given that:

143 people pay ; out of which 38 are under 16 ;

Hence ; 143 - 38 = 105 are over 16

Under 16 = £17.90

£17.90 * 38 = £680.20

16 and Over : = £32.70

£32.70 * 105 = £3433.50

£(680.20 + 3433.50) = £4113.70

Answer:

no it's different 30% would be 12 and 40% would be 16 if it was going into 30 now mark as brainliest

Answer:

In both cases you are really multiplying the same numbers together.

Step-by-step explanation:

30% of 40 would be 30 x 40 x 0.01 = 12

or 0.30 x 40 = 12

40% of 30 would be 40 x 30 x 0.01 = 12

or 30 x 0.40 = 12

Answer:

Option (4) and (5)

Step-by-step explanation:

Option (1)

f(x) = -(x + 1)² - 4

Since, given function has the vertex = (-1, -4) and the parabola is the opening downwards,

Range of the function → (-∞, -4]

Option (2)

f(x) = [tex]2^{x+3}[/tex]

Horizontal asymptote of the function is,

y = 0

Therefore, range of the given function → (0, ∞)

Option (3)

f(x) = x² + 7x - 9

     = x² + 2(3.5)x + (3.5)² - (3.5)² - 9

     = (x + 3.5)²- 12.25 - 9

     = (x + 3.5)²- 21.25

Vertex of the parabola is (-3.5, -21.25) and parabola is opening upwards.

Therefore, range of the function → [-21.25, ∞)

Option (4)

f(x) = -4x + 11

Range of this function is (-∞, ∞).

Option (5)

f(x) = [tex]\frac{2}{3}x-8[/tex]

Range of the function is (-∞, ∞).

Options (4) and (5) are the correct options.

First, find the area of the rectangular shape at the bottom.(think of this as 2 separate shapes then add their areas together to find the final area)

11x8=88 cm

Next, find the area of the triangle.

Area of triangle = base x height /2

11x7=77

77/2=38.5

88+38.5=126.5 cm

Step-by-step explanation:

Answer:

y = 0.1x - 4

Step-by-step explanation:

Given the following data;

Points on the x-axis (x1, x2) = (-3, 7)

Points on the y-axis (y1, y2) = (-7, -6)

First of all, we would find the slope;

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

Slope = (-6 - (-7))/(7 - (-3))

Slope = (-6 + 7)/(7 + 3)

Slope = 1/10

Slope = 0.1

Next, we would write the equation using the formula;

y - y1 = m(x - x1)

y - (-7) = 0.1(x - (-3))

y + 7 = 0.1(x + 3)

y + 7 = 0.1x + 3

y = 0.1x + 3 - 7

y = 0.1x - 4

Answer: 2 2/3 cups of flour

Step-by-step explanation:

Maggie is baking 8 dozen cookies.

8 dozen is equal to 96 cookies as 8×12=96

One recipe is equal to 24 cookies and for each recipe she'll need 2/3 cup of flour.

So you divide 96 by 24 which is equal to 4.

Therefore, you will need 4 recipes worth of flour.

4×2/3=2 2/3

So Maggie would need 2 2/3 cups of flour
