The diameter of a circle is 37 m. Find its area to the nearest whole number.
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

Find the equation of the line shown. y 4 3 2 1 Х -2 -3 4
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

so let's say the sale price is "P", so Nicole would want to know how much will it be P discounted by 18% of P.
Well, the sale price will just be P or 100% of P, minus 18%, the discounted price will be 100% - 18% = 82%, so the discounted price will be 82% of P.

What line would be perpendicular to y − 3=4(x+2)?
A. y − 3=−4(x+2)
B. y − 3=1/4(x+2)
C. y − 3=−1/4(x+2)
D. y − 3=4(x+2)
The line perpendicular to y - 3 = 4(x+2) is y-3 = -1/4(x+2)
When are two lines said to be perpendicular?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)

A model of a sailing boat is made to the scale
1 : 50, i.e a length of 1 cm on the model
represents 50 centimetres on the real yacht.
If one of the sails on the real yacht has an area
of 5 m² what will be the area of the same sail
on the model?
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
write 17/28 and 11/28 as a fraction, percent, ratio and find the difference
please help me with this question
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].

what’s the answer to this problem , figure out the area and perimeter of this triangle
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.

let the unknown side be x , then
using Pythagoras' identity in the right triangle

x² + 441 = 1225 ( subtract 441 from both sides )
x² = 784 ( take square root of both sides )

Quadrilateral Identified:
Area: The evidence:
The quadrilateral is a trapezoid and the area of the quadrilateral is 85.04 square units
How to determine the quadrilateral?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
How to determine the area?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
