Answer:
1 centimet
Step-by-step explanation:
Answer:
A Centimeter!
Step-by-step explanation:
Heard of the Acronym
King Henry Died m Drinking Chocolate Milk
K = King = Kilometers
H = Henry = Hectometers
D = Died = Decameters
M = m = meters
D = Drinking = Decimeters
C = Chocolate = centimeters
The metric system is based on the power of ten.
There are 10 Decimeters in a meter
There are 100 Centimeters (your answer) in a meter
There are 1000 Millimeters in a meter
Similarly:
1 Decameter = 10 meters
1 Hectometer = 100 meters
1 Kilometer = 1000 meters
So you can use it for this:
1 Hectometer = (10x10x10x10)cm or 10,000 cm
In this problem I am starting at 10, and multiplying as many tens as I need to get to Hectometer ( refer acronym).
Centimeters to Decimeters = 10
Decimeters to Meters = 10
Meters to Decameters = 10
Decameters to Hectometers is 10
So we have 4 - 10s so we do 10x10x10x10 or 10,000 cm in a Hectometer
1 cm would equal 0.0001 Hectometer
or 1/10,000 of a cm
If my answer is incorrect, pls correct me!

Answer:
9/25
Step-by-step explanation:
Two pyramids are similar. Their base edges are a ratio of 3:5. Find the ratio of their surface area.
The ratio of the surface area is calculated as the square of the ratio of the edges
Hence,
Ration of surface area = 3²/5²

The sales of lawn mowers t years after a particular model is introduced is given by the function y = 5500 ln(9t + 4), where y is the number of mowers sold. How many mowers will be sold 3 years after a model is introduced? Round the answer to the nearest whole number.
Given:
The function is:
[tex]y=5500\ln (9t+4)[/tex]
Where y is the sales of lawn mowers t years after a particular model is introduced.
To find:
How many mowers will be sold 3 years after a model is introduced?
Solution:
We have,
[tex]y=5500\ln (9t+4)[/tex]
Substituting [tex]t=3[/tex], we get
[tex]y=5500\ln (9(3)+4)[/tex]
[tex]y=5500\ln (27+4)[/tex]
[tex]y=5500\ln (31)[/tex]
On substituting the approximate value of ln(31), we get
[tex]y=5500\times 3.433987[/tex]
[tex]y=18886.9285[/tex]
[tex]y\approx 18887[/tex]
Therefore, the 18887 mowers will be sold 3 years after a model is introduced.
A cone and a sphere both have a radius of 1. If you fill the cone with liquid, and pour it into the sphere, it fits exactly. What is the height of the cone? Show work
Answer and Step-by-step explanation:
First, solve for the volume of the sphere, then solve for the height of the cone using the volume of the sphere (which is said to be equal to the volume of the cone) and the radius given.
Volume formula of Sphere
V = [tex]\frac{4}{3} \pi r^2[/tex]
Substitute 1 in for r
[tex]\frac{4}{3} \pi (1)^2 = \frac{4}{3} \pi = 4.189[/tex] = Volume
Finding the Height of a Cone
Volume formula for Cone: [tex]V = \pi r^2\frac{h}{3}[/tex]
Solve for h
Multiply both sides by 3, then divide by pi and r^2.
[tex]h = \frac{3V}{\pi r^2}[/tex]
Plug in the volume and the radius.
[tex]h = \frac{3(4.189)}{\pi (1)^2}[/tex]
Simplify
[tex]h = \frac{12.567}{\pi }[/tex]
h ≈ 4
4 is approximately the height.

HELP!!!
Fill in the blank to complete this trig ratio.
Answer:
B. y
Step-by-step explanation:
Recall that Cosine = Adjacent over Hypotenuse
The adjacent side of angle "a" is y and the hypotenuse is x
Thus, Cos A = y / x
The value of cos a is y/x.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
Cos x = Base / Hypotenuse
Now,
From the given figure.
Cos a = y / x
Thus,
Cos a = y / x

Determine whether there is a good line of best fit for the given graph. Then, if there is a good line of best fit, determine if the correlation is
positive or negative.
Answer:
The line's slope equals the difference between points' y-coordinates divided by the difference between their x-coordinates. Select any two points on the line of best fit. These points may or may not be actual scatter points on the graph. Subtract the first point's y-coordinate from the second point's y-coordinate.

How do I factor 96d^2-150
Answer:
6(4d + 5)(4d - 5)
Step-by-step explanation:
First, we find the GCF of the two terms. We can notice that both terms are divisible by 6, so we can start by factoring that out:
6(16d^2 - 25)
Now, we can notice that the expression inside the parenthesis models after the special product a^2 - b^2 which factors to (a + b)(a - b). In this case, 16d^2 would correspond to a^2 and 25 would correspond to b^2. We can find the values of a and b:
a^2 = 16d^2
a = 4d
b^2 = 25
b = 5
We can substitute the values fo a and b into the factored form of the special product:
(a + b)(a - b)
(4d + 5)(4d - 5)
We also have the 6 we factored out earlier, so our final answer would be
6(4d + 5)(4d - 5)

WHAT IS THA VAULE OF X
Answer:
49 degrees
Step-by-step explanation:
recall that in a triangle, the angles add up to 180.
so let's set up the equation
x+2x+(x-16)=180 degrees
4x-16=180
4x=196
and so
x=49 degrees
hope this helped
make sure to convert x into angles for each of the angles if it asks for the angles (plug the values in, so 2x-10 would be 2(49)-10, which is 88 i think
