Find the circumference of a circle with diameter 2 cm. Use 3.14 for
Answer:
6.28 cm
Step-by-step explanation:
Given,
Diameter = 2 cm
pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 2 / 2
= 1 cm
Formula : -
Circumference ( circle ) = 2 pi r
2 pi 4
= 2 × 3.14 × 1
= 6.28 cm
Answer:
6.28
Step-by-step explanation:
radius= diameter/2
r=2/2=1
circumference formula=2[tex]\pi[/tex]r
[tex]\pi[/tex]=22/7 or 3.14
So,
2[tex]\pi[/tex]r= 2*3.14*1= 6.28

An expression is shown.
(0.25n - 0.3) – (0.8n - 0.25)
Create an equivalent expression without parentheses.
Answer:
-0.55n - 0.05
Step-by-step explanation:
You can start by distributing:
(0.25n - 0.3) - (0.8n - 0.25)
0.25n - 0.3 - 0.8n + 0.25
Then, you can combine like terms(0.25n & -0.8n; -0.3 & 0.25)
-0.55n - 0.05
Answer:
-0.55n - 0.05
Step-by-step explanation:
(0.25n - 0.3) – (0.8n - 0.25)
When subtracting the signs change
0.25n - 0.3 - 0.8n + 0.25
Regroup like terms
0.25n - 0.8n - 0.3 + .25
Combine like terms
-0.55n - 0.05

What single transformation was applied to triangle A to get triangle B? Links will be reported
Answer:
Rotation:
Step-by-step explanation:
Translation is usually movements like up, down, left, right.
Dilation is when one shape is bigger/smaller than the other, but still congruent.
Reflections are usually done over an axis (x or y), and don't change the degree at which a shape is turned. From looking at the triangles, you can see that one triangle was turned clockwise.

a block of wood has a mass of 3.5 kilogram. the wood has density 0.065 kg/m3
work out the volume of the block of wood
Step-by-step explanation:
Given :-
A block of wood has a mass of 3.5 kilogram. The wood has density 0.065 kg/m³.And we need to find out the volume of the wood. Density , volume and mass are related as ,
Density :-
Mass per unit Volume .[tex]\implies\rm Density =\dfrac{Mass}{Volume}[/tex]
Substitute the respective values :-
[tex]\implies\rm Density =\dfrac{Mass}{Volume}\\\\\rm\implies 0.065 kg/m^3=\dfrac{3.5kg}{V}\\\\\rm\implies Volume = \dfrac{3.5kg}{0.065 kg/m^3}\\\\\implies\boxed{\red{\rm Volume = 53.84 m^3}}[/tex]
Hence the volume is 53.84 m³ .
Which number completes the table for y = x^2?
a.) -9
b.) 9
c.) 6
d.) -6
Answer:
B
Step-by-step explanation:
We can substitute the x value given, -3, into our equation, y = x^2, to get what the y would be:
y = x^2
y = (-3)^2
When a negative number is squared, it is positive, so (-3)^2 = 9, and:
y = 9
This is option b
Answer:
B) 9
Step-by-step explanation:
We are given the equation y = x^2 for the table, and a x value.
To find the y value that corresponds to that x value, we must plug the x value in the equation.
Y =x^2
Y= -3^2
Y=9

12,000= 120 tens true or false
Answer:false
Step-by-step explanation:120 tens would be 1200
The number 12,000 does not equal 120 tens. Thus, it is false.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
12,000 = 120 tens
Simplify the equation, then we have
12,000 = 120 x 10
12,000 ≠ 1,200
The given equation is false.

HELP: Cho charges $1500 to build a small deck and $2500 to build a large deck. During the spring and summer, she built 5 more small decks than large decks.
If she earned $23,500 how many of each type of deck did she build?
Answer:
if she build x numbers of large decks, therefore small decks would be (x + 5)
1500*(x+5)+2500x =23500
1500x+7500+2500x=23500
4000x+7500 =23500
4000x=23500-7500
4000x=16000
x=4
4+5=9
cho built 4 large decks and 9 small decks
Amy has three times as many Star Wars toys as Carly. Total they have 160 Star Wars toys. How many Star Wars toys does Amy have?
Answer:
53
Step-by-step explanation:
Amy has 120 star war toys.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amy:
Number of toys = 3x
Carly:
Number of toys = x
Now,
In total, they have 160 Star Wars toys.
So,
x + 3x = 160
4x = 160
x = 40
Now,
3x = 3 x 40 = 120
x = 40.
Thus,
Amy has 120 toys.
Carly has 40 toys.
