I need help with Shape equation puzzle 2 it’s due tomorrow
Hey there! I'm happy to help!
First of all, I would guide you to decipher clue 2 first. It is the only one that has just one shape, so then we can find the value of that shape.
To find what this circle is, we just divide 12 by three to see what 3 times the circle is!
12÷3=4
CIRCLE=4
-----------------------------------------------------------------
Now, let's look at clue one. This one only has two shapes, and it has the circle, which we already know.
We know that our circle is 4, so 5 circles will be 20.
This means that the diamond plus two will be 20, so let's just subtract 2 from 20!
20-2=18
DIAMOND=18
-----------------------------------------------------------------
Finally, let's look at the third one. This one is the trickiest. Two circles is eight, and that is going to be equal to our diamond (eighteen) and two triangles.
How is that going to work?
The triangles make us go backwards! Otherwise known as negative numbers!
To get from eighteen to eight, we have to go back ten. Ten is going to be made up of two triangles, so we just divide ten by two so each triangle gets an equal amount.
10÷2=5
TRIANGLE=5
-----------------------------------------------------------------
Have a wonderful day and keep on learning! :D
An equation is formed of two equal expressions. The value of the Circle, Diamond, and the triangle is 4, 18, and -5, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the circle be represented by C, the diamond be represented by D, and the triangle be represented by T.
Now, the clues can be rewritten as,
D + 2 = 5(C)
3(C) = 12
2(C) = D + 2(T)
Since the second clue has only one variable C, let's solve it first,
3(C) = 12
C = 12 / 3
C = 4
Further, the first clue has two variables C and D, and the value of C is already known, therefore, solve it second.
D + 2 = 5(C)
D + 2 = 5(4)
D + 2 = 20
D = 20 - 2
D = 18
Furthermore, by solving the last Clue we will get,
2(C) = D + 2(T)
Substitute the known values,
2(4) = 18 + 2(T)
8 = 18 + 2T
8 - 18 = 2T
-10 = 2T
T = -5
Hence, the value of the Circle, Diamond, and the triangle is 4, 18, and -5, respectively.

of the cost of Tristan's helmet. If Zeke gives the cashier a $20 bill, how much change will he receive?
Answer:
Zeke will receive $2.75.
Step-by-step explanation:
Helmet cost: (3/5) x 28.75 = $17.25
Gives = $20
20 - 17.25 = 2.75

Which fraction is equal to 0.98
The most simplified version of it is 49/50
Answer:
98/100
Step-by-step explanation:
The number after the decimal is the tenths place. And the second number after the decimal is in the hundredths place. And so on...
So .98 would be in the hundredths place making it 98/100.
If you want to simplify it even more, you would make it 49/50.

Answer:
x = 70
Step-by-step explanation:
To find the value of x we need to
we know that the figure is an isosceles triangle so the base angles will be equal
we also know that angle sum of triangle is 180
so
40 + x + x = 180
40 + 2x = 180
2x = 180 - 40
2x = 140
x = 140/2
x = 70
????? what is the value of c?
Answer:
X=64°
Step-by-step explanation:
Solution,
x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.
x+54°-54°=118°-54°
x=64°
Answer:
64 degrees
The Process:
54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.

urgent answer needed pls
Answer:
pi*z^2*a or "pizza"
Step-by-step explanation:
The dimensions given describe a cylinder, for which the basic volume formula would be base x height.
The base would be a circle, with the radius z as given while the height is a.
The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.
Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a
Side note:
z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".

A goat is grazing outside of a rectangular barn that has dimensions 20 ft by 30 ft.
He's tied to a corner of the barn with a 12 ft rope. Find the grazing area of the goat.
Answer:
108π ft² or 339.29 ft²Step-by-step explanation:
Refer to attached picture.
The grazing area of the goat is 3/4 of area of circle with 12 ft radius:
A = 3/4(πr²) = 3/4(π*12²) = 108π or 339.29 ft²Tied to the corner
Means 1part among 4parts of circle or a quarter area
So grazing field

translate it down 2 units. What is the relationship between the original line segment and the transformed line segment? If you

glasses are excluded. What is this an example of?
A. Selection bias
B. Nonselection bias
C. Nonresponse bias
D. Response bias
SUBMIT
Answer:
A. Selection Bias
Step-by-step explanation:
Selection bias is the bias introduced by the selection of individuals, groups, or data for analysis in such a way that proper randomization is not achieved, thereby ensuring that the sample obtained is not representative of the population intended to be analyzed. This is represented by choosing the students without glasses.
Answer:

dy/dx y = 3root(4x+1) -2x
Answer:
Step-by-step explanation:
y = 3(4x + 1)^1/2 - 2x
dy/dx = 3*1/2(4x + 1)^-1/2 * 4 - 2
= 4 * 1.5 (4x + 1)^-1/2 - 2
= 6(4x + 1)^-1/2 - 2
= [6/√(4x + 1)] - 2
y = 3(4x + 1)^1/2 - 2x
∫3(4x + 1)^1/2 - 2x . dx
= 3 * 1/4 * (4x + 1)^3/2 / 3/2 - x^2 + C
= 3/4 * 2/3 (4x + 1)^3/2 - x^2 + C
= 1/2((4x + 1)^3/2 - 2x^2) + C.
Answer:
Step-by-step explanation:
[tex]y=3*\sqrt{4x+1} -2x\\\\y'=\dfrac{dy}{dx} =\dfrac{3}{2*\sqrt{4x+1} } -2\\\\\\\int {(3*\sqrt{4x+1} -2x}) \, dx \\\\=\dfrac{3}{4} *\int {4*(4x+1)}^{\frac{1}{2}} \, dx -2\int {x} \, dx \\\\=\dfrac{-3}{4}*\sqrt{(4x+1)^3} *\dfrac{2}{3} }-x^2+C\\\\=\dfrac{\sqrt{(4x+1)^3}}{2} -x^2+C[/tex]
5x^2 - x + 9 when x = -5

139
Step-by-step explanation:
If x=-5
then
5*-5^2-(-5)+9
5*25+5+9
139
Answer: 139
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
5x² - x + 9
x = -5
Substitute value into the expression
=5(-5)² - (-5) + 9
Simplify exponents
=5 (25) + 5 + 9
Simplify by multiplication
=125 + 5 +9
Simplify by addition
