Answer:
25/12
Step-by-step explanation:
1/2 + 2/5s = s - 3/4
2/5s = s - 5/4
-3/5s = -5/4
s = 25/12
Find the perimeter of a regular octagon with an apothem of 6 feet and an area of 120 square feet
Step-by-step explanation:
A = (n × s × a)2 A = ( n × s × a ) 2
(120×6)2
240×12
2880
The perimeter of the Octagon is P = 30 feet
What is the perimeter of a polygon?The perimeter of the regular polygon with apothem and area is given by the equation
Perimeter of Polygon P = ( Area x 2 ) / Apothem
where apothem is a line from the center of a regular polygon at right angles to any of its sides
Given data ,
Let the perimeter of the octagon be represented as P
Now , the apothem a = 6 feet
The area of octagon A = 120 feet²
where Perimeter of Polygon P = ( Area x 2 ) / Apothem
P = ( 120 x 2 ) / 6
P = 30 feet
Therefore , the value of P is 30 feet
Hence , the perimeter of polygon is 30 feet

Which expression is NOT equivalent to 40 + 20
Answer:
4(10 + 16)
Step-by-step explanation:
40 + 20 = 60, so none of the answers can be 60.
Let's look at all of the answer choices:
10(4 + 2) = 60
4(10 + 16) = 104 (this is the answer!)
5(8 + 4) = 60
2(20 + 10) = 60
what is 2.1 times 3.2 find the missing partial products HELP.
Given:
The area model for [tex]2.1\times 3.2[/tex].
To find:
The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:
[tex]2\times 3=6[/tex]
[tex]2\times 0.2=0.4[/tex]
[tex]0.1\times 3=0.3[/tex]
[tex]0.1\times 0.2=0.02[/tex]
The complete area model is shown below.
After adding all areas of the area model, we get
[tex]6+0.4+0.3+0.02=6.72[/tex]
Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

S. The area of a stage for a concert is 216 square feet. The length is 6 times the width. Find the dimensions of
the stage
Answer:
Width=6 Length=36
Step-by-step explanation:
The stage is rectangular since the length is not equal to width.
We use the formula (Width × Length) to obtain the area of any rectangle.
But the Length is 6 times the Width, therefore we equate the formula for the area of stage as
Width × 6Width = 216
we get Width as 6 and 6width which is the length as 36
Josh is going to the store with $60 to buy candy. bags of candy corn cost $3 & bags of chocolate cost $5 he needs to buy at least 20 bags of candy.
What do I put for the blank space? 3x+5y_60
Answer:
3a+5b
Step-by-step explanation:
Variable 1: a = candy corn
Variable 2: b = chocolate
Inequality 1: 60 ≥ 3a + 5b
Inequality 2: 20 ≤ 3a + 5b
The inequalities are as such because Josh needs to spend no greater than $60. He must also buy at least 20 bags of candy. The candy corn costs $3, while the chocolate costs $5. An expression for the total cost of the candy would be 3a + 5b.

Theresa rolls a 12-sided dice and flips a
coin. What is the probability that she will
roll a 7 and land on heads?
Answer:
The probability is 1/24
Step-by-step explanation:
For a 12-sided dice, there are 12 different possible results
so the possibility of rolling a 7 is just one of the results
The probability of this is simply 1/12
For landing on head, the probability is 1/2
So the probability of the event occurring is the product of these two events
We have this as;
1/2 * 1/12 = 1/24

Which statement below about roots is false.Immersive Reader (5 Points) Simplified radicals have a positive and a negative root. A radicand is the symbol used when working with roots. Exponents and Roots are inverses Roots can be squared, cubed, quadrupled. Or more.
Answer:
Statement (B)
Step-by-step explanation:
Which statement below about roots is false?
Let's arrange the statements by assigning option-letters a, b, c, d to them.
(A) Simplified radicals have a positive and a negative root.
This is true, as the root of any number is either a positive or a negative; especially if the rooting index is an even number like 2 or 4. For example, the square root (when the index is 2) of 9 is either +3 or -3. To check, find their squares. +3 x +3 = 9 and -3 x -3 = 9.
(B) A radicand is the symbol used when working with roots.
This statement is false, as the name for the symbol used in root operations is "radical symbol". A radicand is the number or expression whose roots are about to be found. It is the expression that lies under or inside the radical symbol!
(C) Exponents and Roots are inverses.
Exponents are the powers to which mathematical expressions are raised. Roots are the indexes by which mathematical expressions are divided. Exponents are hence the opposites or inverses of roots.
(D) Roots can be squared, cubed, quadrupled, or raised to higher powers.
Yes! The root of a mathematical expression or figure can be raised to any number or power, be it 2 (square), 3 (cube), 4 (quadruple), 5 (quintuple) or 100 (cent).
Which of these sequences shows the flow of energy from the sun through organisms on Earth?
1 sun → producer → consumer → decomposer
2 sun → consumer-producer → decomposer
Answer:
I'm pretty sure it's number 1. The sun goes to plants and the plants get consumed. I don't think that the consumer eats the sun... just kidding. But yeah it's the first one.
1 sun → producer → consumer → decomposer

f(x)= x^2 - 7x +12
The above equation is in standard form. Write the above equation in factored form
f(x) = (x-r1)(x-r2)
r1 represents first root, r2 represetnts second root
What are the roots?
Remember, x-r1 = 0 and x-r2=0
Answer:
f(x) = (x - 3)(x - 4)
Step-by-step explanation:
f(x)= x^2 - 7x +12 factors immediately into f(x) = (x - 3)(x - 4).
The roots are {3, 4}

Answer:
27 boxes
Step-by-step explanation:
214 ÷ 8 = 26.75
Because you can't get .75 of a box, Jacob needs at least 27 boxes.

Answer:
B = -1
Your answer would be C
Answer:
b = -1
Step-by-step explanation:
-3(2x - 3) + 5x = bx + 9
-3 x 2x = -6x
-3 x -3 = 9
-6x + 9 + 5x = bx + 9
-6x + 5x = -1x
-1x + 9 = bx + 9

The art club is designing a rectangular mural for the school hallway. Three corners are located at (-1, -1), (-1, 1), and (4, 1) on teh coordinate plane. What would be the forth vertex on the coordinate plane below?
Answer:
The fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex]. The graph of the figure is included below.
Step-by-step explanation:
Let be [tex]X(x,y)[/tex], [tex]Y(x,y)[/tex], [tex]Z(x,y)[/tex] and [tex]W(x,y)[/tex] so that a rectangle is formed. Hence, we must satisfy the following conditions:
[tex]X(x,y) = (a, c)[/tex] (1)
[tex]Y(x,y) = (a, d)[/tex] (2)
[tex]Z(x,y) = (b, c)[/tex] (3)
[tex]W(x,y) = (b, d)[/tex] (4)
[tex]a < b[/tex] (5)
[tex]c < d[/tex] (6)
If we know that [tex]a = -1[/tex], [tex]b = 4[/tex], [tex]c = -1[/tex], [tex]d = 1[/tex], then we have the following points:
[tex]X(x,y) = (-1, -1)[/tex]
[tex]Y(x,y) = (-1, 1)[/tex]
[tex]Z(x,y) = (4, -1)[/tex]
[tex]W(x,y) = (4,1)[/tex]
Then, the fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex].
