What is the best approximation of the length of the radius in a circle with an area of 167 m2?
a. 4.6 meters
b.4.0 meters
c. 2.3 meters
d.5.1 meters
Answer:
r = 7.3 m
Step-by-step explanation:
A = (pi)(radius)^2, so, if A = 167 m^2, r^2 is found as follows:
167 m^2
r^2 = -------------- = 53.158 m^2
3.14
Taking the square root of both sides, we get
r = 7.3 m
This is correct, because A = (pi)(radius)^2 becomes (3.14)(7.3 m)^2 = 167.4 m^2
Solve for y. 4- 2y + 8 = -6 y = [?]
Answer:
y=9
Step-by-step explanation:
4-2y+8=-6
-2y=-4-8-6
-2y=-18 divide by -2 both side
y=-18/-2
y=9

17) In a triangle ABC, BC=8cm, AC=12cm and angle ABC=120
a) Calculate the length of AB, correct to one decimal place (4marks)
Answer:
17.4cm
Step-by-step explanation
17) In a triangle ABC, BC=8cm, AC=12cm and angle ABC=120
To get the length of AB, we will use the cosine rule
AB² = BC² + AC² - 2(BC)(AC) cos <ABC
AB² = 8² + 12² - 2(8)(12) cos 120
AB² = 64 + 144 - 192cos12
AB² = 208 - (-96)
AB² = 208 +96
AB² = 208 - (-96)
AB² = 304
AB² = 17.4cm
Hence the length of AB is 17.4cm

find the interior angles of a regular polygon which has 6, 10 and 20 sides
Answer:
(6)=120°
(10)=72°
(20)=36°
Step-by-step explanation:
(n-2)×180°
(6-2)×180°=720°
6÷720°=120°
10÷720°=72°
20÷720°=36°
Find the equation of a line that passes through points (9,3) and (-6,5)?
Answer:
Y= X - 31.5
Step-by-step explanation:
find the gradient then the equation
Answer:
y-3 = -2/15 (x-9)
Step-by-step explanation:
First, we should find the gradient, m, which is [tex]\frac{rise (change.in.the.y.value)}{run (change.in.the.x.value)}[/tex]
This is [tex]\frac{3-5}{9-(-6)} =-\frac{2}{15}[/tex]
A linear (straight) line has a general equation y=mx+c
y = [tex]-\frac{2}{15\\}[/tex]x+c
We can rewrite the equation into the general form:
y-y1 = m(x-x1)
where y1 is the value of a y coordinate and x1 is the x value of the coordinate that the y1 value was taken from.
This stems from the idea that 0 = 0.
To make that equation true, we can make both sides equal to 0.
To do that, y - y1 has to be - and x-x1 has to be zero. m can be ignored as anything multiplied by 0 is 0.
Up until here, y1 and x1 are arbitrary constants. They are values that we have to find. However, we don't actually. We have coordinates that the x and y will equal to. (9,3)
Because 9 - 9 = 0 and 3 - 3 = 0, we can state that the value of y1 is 3 and x1 is 9.
Hence, the equation is y-3 = -2/15 (x-9)
You can rearrange the equation to make it into the form y = mx + c, but this is usually not necessary.
I hope this helped.

which of the following is the correct expanded form for the series below?
Answer:
A. 7 + 7/2 + 7/3 + 7/4Step-by-step explanation:
This is the sum of the first 4 terms, substitute n for each term:
4
∑ [tex]\frac{7}{n}[/tex] = 7/1 + 7/2 + 7/3 + 7/4
n=1
Correct choice is A
[tex] \displaystyle \sum^{4} _{n = 1} \: \frac{7}{n} = \: 7 + \frac{7}{2} + \frac{7}{3} + \frac{7}{4} [/tex]

Work out the size of an exterior and an interior angle of a regular 16-sided
polygon.
Answer:
exterior angle: 22.5°, interior angle: 157.5°
Step-by-step explanation:
the formula for the measure of each Interior Angle in a regular polygon: [tex]\frac{180(n-2)}{n}[/tex], n = # of sides
=> [tex]\frac{180(16 - 2)}{16}[/tex] = 157.5°
the formula for the measure of each Exterior Angle in a regular polygon: [tex]\frac{360}{n}[/tex]
=> [tex]\frac{360}{16}[/tex] = 22.5°

Answer:
D) (-2, -9)
Step-by-step explanation:
X( -11, 8)
M(-6.5, -0.5)
-11 - (-6.5) = -11 + 6.5 = -4.5
8 - (-0.5) = 8 + 0.5 = 8.5
To get from Midpoint to endpoint:
(x , y) → (x - 4.5, y + 8.5)
Y endpoint:
M(-6.5, -0.5) → (-6.5 + 4.5, -0.5 - 8.5)
Y( -2, -9)

What are Even number?
Even numbers are 2,4,6,8,10 :) ✨
Answer:
Any number that can be exactly divided by 2 is called as an even number. Even numbers always end up with the last digit as 0, 2, 4, 6 or 8. Some examples of even numbers are 2, 4, 6, 8, 10, 12, 14, 16.
Use the coordinate plane. Identity the ordered pair
that names each point.

Alex has six candy bars he wants to cut into fifths. How many 1/5 size pieces will he have
Answer:
30 pieces.
Step-by-step explanation:
According to the word problem, Alex wants to cut all six of his candy bars into fifths.
5/5 = one whole candy bar.
If there will 5 pieces for every candy bar, we can multiply 5 by 6.
5 x 6 = 30.
There will be 30 of the 1/5 size pieces.

1. Length of HF =??
Round to the nearest tenth
2. Length of EG =??
3. What kind of quadrilateral is this?
Parallelogram
Rectangle
Rhombus
Square
Trapezoid
Kite
Answer:
Use distance formula to find the length of the segments
1. H = (-3, 0), F = (3, 2)
HF = [tex]\sqrt{(3 + 3)^2+2^2} = \sqrt{40}[/tex] = 6.3 (rounded)2. E = (1, 4), G = (-1, -2)
EG = [tex]\sqrt{(-1 - 1)^2+(-2-4)^2} = \sqrt{40}[/tex] = 6.33. We see the diagonals are congruent, opposite sides are parallel.
The above is the property of a rectangle
