Answer:
4√15
Step-by-step explanation:
The geometric mean of x and y is √(xy).
So here we have:
√(12*20)
= √240
= √(16*15)
= √16√15
= 4√15.
A = 2^3 x 3 x 5
B = 22 x 3 x 52
(b) Write down the highest common factor (HCF) of A and B.
Answer:
Step-by-step explanation:
B = 22 × 3 × 52?—or is it supposed to be
B = 2² × 3 × 5² ?
A = 2² × 3 × 5
B = 2² × 3 × 5²
GCF = 2² × 3 × 5 = 60
A = 2² × 3 × 5
B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13
GCF = 2² × 3 × 5 = 60

Circle D is below.
What is the arc measure of BAC in degrees?
(7n+12)
(13n-16)
(6n)
Answer:
[tex]BAC = 276[/tex]
Step-by-step explanation:
Given
See attachment
Required
Find BAC
The sum of [tex]angles\ at\ a\ point[/tex] is 360.
So:
[tex]7n + 12 + 13n - 16 + 6n = 360[/tex]
Collect like terms
[tex]7n + 13n + 6n = 360 + 16 - 12[/tex]
[tex]26n = 364[/tex]
Solve for n
[tex]n = 364/26[/tex]
[tex]n = 14[/tex]
From the circle:
[tex]BAC = 7n + 12 + 13n - 16[/tex]
Substitute 14 for n
[tex]BAC = 7*14 + 12 + 13*14 - 16[/tex]
[tex]BAC = 276[/tex]

Find the volume of the cone.
What is the radius?
12
What is the height?
5
Write the volume in terms of pi (1/3 times radius squared times the height only).
π km3
Solve for the volume (Multiply by 3.14 this time)
Answer:
Step-by-step explanation:
Your first two answers are incorrect. Radius = 5 km
Height = 12 km
volume of cone = πr²h/3 = π5²⋅12 = 300π km³
300π ≈ 942 km³

-4(x-3)^2+7=43 please show how you got your answers step by step pleaseee
Answer:
(x - 3)² = -9
Solution:
Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.
Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.
Answer:
x=3+3i, 3-3i
Step-by-step explanation:
-4(x-3)²+7=43
(x-3)(x-3)= x²-6x+9
-4(x²-6x+9)+7=43
-4x²+24x-36+7=43
-4x²+24x-29=43
-4x²+24x-72=0
-x²+6x-18=0
Quadratic formula: -b+√(b²-4ac) / 2a
-(-6)+√((-6)²-4(1)(18)) / 2(1)
6+√(36-72) /2
6+√(-36) / 2
x=6+6i / 2
x=3+3i, 3-3i

Find m w in rhombus TUVW.
Find the interior angle sum of this polygon.
Can someone help????
===================================================
Explanation:
See the diagram below. It shows there are 10 sides, so n = 10.
We'll plug this value of n into the formula below to find the sum of all ten interior angles
S = sum of interior angles
S = 180(n-2)
S = 180(10-2)
S = 180(8)
S = 1440 degrees
---------------
A different approach:
Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.
We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.
Each interior angle adjacent to this 36 degree exterior angle is
180-E = 180-36 = 144 degrees
Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees
Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.
The table below gives the dimensions of a bridge and a scale model of the bridge.
Find the scale factor of the model to the real bridge.
Write your answer as a fraction in simplest form.
Answer:
Scale factor = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Formula for the scale factor is,
Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]
= [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]
= [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]
= [tex]\frac{7}{35}[/tex]
= [tex]\frac{1}{5}[/tex]
Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]
