Answer:

1075

Step-by-step explanation:

Let us say pi/ is 3.14

Diameter is radius times 2, so the radius is half of 37(aka 18.5)

A = n[tex]x^{2}[/tex]

A = 3.14 x 18.5²

A = 3.14 x 342.25

A =  1074.665

snice 6 > 4

A = 1075

Answer:

17/28

60.7%

17:28

11/28

39.3%

11:28

Difference:  [tex]\frac{3}{14}[/tex]

Explanation:

A fraction can be turned into a percent by dividing the numerator by the denominator and multiplying the result by 100%.

For example:

17/28 = 0.607

0.607 * 100% = 60.7%

A fraction can be turned into a ratio by writing it like this:

numerator:denominator

For example:

11/28

11:28

To find the difference between 2 fractions with the same denominator, simply subtract the 2 numerators.

For example:

[tex]\frac{17}{28} - \frac{11}{28}[/tex]

You subtract 11 from 17, then put the resulting 6 in the fraction with the same denominator. This results in [tex]\frac{6}{28}[/tex] which can be simplified to [tex]\frac{3}{14}[/tex].

Answer:

Step-by-step explanation:

A triangular pyramid has 6 edges, 4 vertices, and 1 base

The quadrilateral is a trapezoid and the area of the quadrilateral is 85.04 square units

The vertices are given as:

A:(-2, 3) B:(4, -6) C:(10, 2) D:(6, 8)

Next, we plot the vertices (see attachment)

From the attached graph, we can see that the quadrilateral is a trapezoid

From the plot, we have the following features:

Height: AD

Parallel sides: CD and AB

Calculate the lengths using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]AD = \sqrt{(-2 -6)^2 + (3 -8)^2}[/tex]

[tex]AD = \sqrt{89}[/tex]

[tex]CD = \sqrt{(10 -6)^2 + (2 -8)^2}[/tex]

[tex]CD = \sqrt{52}[/tex]

[tex]AB = \sqrt{(-2 -4)^2 + (3 +6)^2}[/tex]

[tex]AB = \sqrt{117}[/tex]

The area is then calculated as:

Area = 0.5 * (CD + AB) * AD

This gives

Area = 0.5 * (√52 + √117) * √89

Evaluate

Area = 85.04

Hence, the area of the quadrilateral is 85.04 square units

Answer:

y = 1/2x + 0.5

or

y = 1/2x + 1/2

Step-by-step explanation:

y = mx + b

b is y-intercept:

when x = 0, y = 0.5 (when the line cross the vertical (y) axis of the graph)

the point is (0, 0.5) so b = 0.5

m is slope:

slope = rise / run

rise = 1

run = 2

for every 2 x values, y increase by 1

slope (m) = 1/2

Answer:

Answer:

28 cm

Step-by-step explanation:

let the unknown side be x , then

using Pythagoras' identity in the right triangle

x² + 21² = 35²

x² + 441 = 1225 ( subtract 441 from both sides )

x² = 784 ( take square root of both sides )

x = [tex]\sqrt{784}[/tex] = 28

Answer:

the unknown side is 28

Step-by-step explanation:

[tex]a^{2} + b^{2} = c^{2} \\c = 35\\a = 21\\21^{2} + b^{2} = 35^{2}\\441 + b^{2} = 1225\\b^{2} = 1225 - 441\\b^{2} = 784\\b = \sqrt{784} \\b = 28[/tex]

Answer:

A: 0.3318 m^2  P: 2.66

Step-by-step explanation:

The perimeter is only adding each of the side lengths, so that's not much of an issue. The equation for the area of a triangle is A = (b x h)/2, with "b" being the base length and "h" representing the triangle's height. We must first multiply the base and height, 0.84 x 0.79. This makes 0.6636 which we will then divide by 2. Our area is now proven to be 0.3318 square meters.

The solid was obtained by rotating the region bounded by x² = 27y, x = 0, and y = 1 about the y-axis is 42.411 cubic units.

It is the reverse of differentiation.

Consider the solid obtained by rotating the region bounded by the given curves about the y-axis.

[tex]\rm x = 3\sqrt{3y} \ or \ x^2 = 27y[/tex]

x = 0, and y = 1

Then the volume of the solid will be

[tex]\rm Volume = \int _{0}^{1} \pi x^2 dy\\\\Volume = \int _{0}^{1} \pi 27y dy\\\\Volume = 27\pi \int _{0}^{1} \ ydy\\\\Volume = 27 \pi [\dfrac{y^2}{2}] _{0}^{1}\\\\[/tex]

[tex]\rm Volume = 13.5 \times \pi \times [y^2] _{0}^{1}\\\\Volume = 13.5 \times \pi \times (1^2 - 0^2)\\\\Volume = 42.411 \ cubic \ units[/tex]

The line perpendicular to y - 3 = 4(x+2) is y-3 = -1/4(x+2)

Two lines are said to be perpendicular if the product of their gradient is -1.

which means m1 x m2 = -1

Analysis:

y - 3 = 4(x+2)

y = 4x + 8+3

y = 4x + 11    m1 = 4

so m1 x m2 = -1

m2 = -1/4

so from the options, the equation with a gradient x = -1/4 is C, y-3 = -1/4(x+2)

In conclusion, the line that would be perpendicular to y - 3 = 4(x+2)

Answer:

[tex]20cm^2[/tex]

Step-by-step explanation:

We are talking of a linear scale ie 1 cm = 50 cm

So if the real yacht length is 10 meters(10,000 cm), then the model length will be 10000/50 = 200 cm

However, when talking about areas, the scale factor is different. We cannot simply divide 5m by 50

Let's say the sail height is 1 meter and the sail width is 5 meters which will give a sail area of 5 sqm.

The scaled height would be 100/50 = 2cm and scaled width will be 500/50 = 10 cm

So the area of the sail on the model will be 2 x 10 =200 square cm

In short, area of sail on model = (area of sail on real yacht( ÷ (50 x 50)

Since there are 10,000 square cm to 1 square meter we get the answer as 5 x 10000/2500 = 20 square cm
