Answer:
4560
Step-by-step explanation:
There are 3 zeros in 1000. If you are multiplying, move the decimal place over however many places to the right that there are zeros. For example,
4.56 x 1000
45.6 x 100
456 x 10
4560 x 1
We moved the decimal place to the right one every time we removed a zero.
This method is extremely useful for multiplying by 1, 10, 100, etc.
Hope this helps!

A triangle has a base that is 19 inches long, and a height of 12 inches. What is the area of the triangle?
Answer:
[tex]144[/tex] [tex]inches^2[/tex]
Step-by-step explanation:
Hey there!
In order to find the area of a triangle, you need to:
Multplipy the base by the height
Then you take that product and multiply it by 1/2 (basically divide it by 2)
Then you get your area!
Base: 19
Height: 12
19 x 12
228
228 x 1/2
228/2
114
So the area of this triangle is [tex]144[/tex] [tex]inches^2[/tex]

The rangers at two park stations spot a signal flare at the same time. Based on the measurements shown in the diagram, what is the distance between park station 1 and the point where the flare was set off? Round to the nearest tenth.
The distance between park station 1 and the point where the flare was set off is 73.9 km.
What is distance?Distance is the length between two points expressed in meters or kilometers.
To calculate the distance between park station 1 and the point where the flare was set off can be calculated using Sine Rule
Formula:
a/sinA = b/sinB....................... Equation 1Where:
a = Distance between park station 1 and the point where the flare was set off.Make a the subject of the equation
a = bsinA/sinB............ Equation 2From the diagram,
Given:
A = 59°B = (180-59-75) = 46°b = 6.2 kmSubstitute these values into equation 2
a = 6.2(sin59°)/(sin46°)a = 73.9 kmHence, the distance between park station 1 and the point where the flare was set off is 73.9 km.

the perimeter of an equilateral triangle is 6cm find its area
Answer:
√3 cm
or
1.73 cm to the nearest hundredth.
Step-by-step explanation:
Each side must be 2 cm long
Using Heron's formula
Area = √(s(s-a)(s-b)(s-c) where s = semi-perimeter, a , b and c are the 3 side lengths.
So here s = 6/2 = 3 and all the sides = 2 so
Area = √(3(3-2)^3
= √3 cm.
The probability of pulling a blue marble from a bag is 0.25.
Which bags of marbles are good models for this probability?
Select two that apply.
✓5 yellow, 9 red, 3 blue
6 yellow, 5 red, 10 blue, 12 green, 7 purple
10 yellow, 3 red, 10 blue
O 1 yellow, 2 red, 3 blue, 5 green, 1 purple
Answer:
The second and fourth choices.
Step-by-step explanation:
Probability of getting a blue marble = 0.25 = 1/4.
Therefore the number of blue bags will be 1/4 of the total of marbles.
The second choice has 10 blue marbles out of a total of 40, so this is one.
The 4th bag has 12 marbles of which 3 are blue. 3/12 = 1/4 so this is another answer which is correct.
Answer:
option 2 and 4
Step-by-step explanation:
add up all the values given then divide the number of blue given.

The taylor series about x=5 for a certain function converges
The evaluation of the function [tex]f(x)=e^x[/tex] at a=0 and x=5 by the taylor series will have a value 65.37.
What is taylor's series?We know the fromula of taylor series is given as:
[tex]f(x)=f(a)+\dfrac{f'((a)}{1!}(x-a)+\dfrac{f''(a)}{2!}(x-a)^2+\dfrac{f'''(a)}{3!}(x-a)^3.................[/tex]

[tex]f(x)=1+x+\dfrac{x^2}{2!}+\dfrac{x^3}{3!}+\dfrac{x^4}{4!}[/tex]

what is the answer for (b)?
Answer:
(b) ∠ADC = 60°Step-by-step explanation:
ΔBOC is isosceles and M is the midpoint of BC
then
∠MOC = ∠BOM = 30°
then
∠BOC = 60°
……………………
OC // AB
then
∠ABO = ∠BOC = 60° (alternate-interior angles)
……………………………………………
In ΔOAB ,we have :
OA = OB and ∠ABO = 60°
Then ,
ΔOAB is an equilateral triangle.
then
∠AOB = 60°
……………………………
We get :
∠AOC = ∠AOB + ∠BOC = 60° + 60° = 120°
……………………………………………………
∠ADC = ∠AOC/2 = 120/2 = 60°

---Multiply a x c
Quadratic Form: ax^2 + bx + c
4 x -25 = -100
---Find a factor pair of -100 that adds up to -15
-20 x 5 = - 100
-20 + 5 = -15
---Separate the b term into your two factors
4n^2 + 5n - 20n - 25
This can take some trial and error (though there are only two options) because when you factor, you want the inside of the parentheses to be the same. If you look at the next step, (4n + 5) appears twice.
---Factor each binomial
n(4n + 5) - 5 (4n + 5)
---Rewrite
(n - 5)(4n + 5)
What you're really doing here is factoring out the (4n + 5), which leaves you with the terms that you factored out in the previous step. You then combine these terms into one set of parenthesis.

B= 29.25/ 3.25
The length of the base of the triangle is 9 centimeters.
What is the base length of the triangle?The area of a triangle is simply expressed as half base multiplied by height.
Area A = 1/2 × base length × height
Given the dimensions of the triangle:
Area A = 29.25 square centimeters
Height = 6.5 centimeters
Base length =?
To find the height of the triangle, plug the given values into the above formula and solve for h:
Area A = 1/2 × base length × height
29.25 = 1/2 × base length × 6.5
29.25 = base length × 3.25
Base length = 29.25 / 3.25
Base length = 9 cm.
Therefore, the base length measures 9 centimeters.
