Answer:
s = 9 cm
p = 8s
p = 72 cm
Step-by-step explanation:
s = p ÷ 8
Where,
s = length of a side
p = perimeter of a regular octagon
find s when p = 72 cm
s = p ÷ 8
= 72 cm ÷ 8
= 9 cm
s = 9 cm
Formula for p in terms of a
s = p ÷ 8
Equivalent to
s = p/8
Cross product
s * 8 = p
p = 8s
Find p when s = 9 cm
p = 8s
p = 8 * 9 cm
= 72 cm
p = 72 cm
Read the excerpt from Heart of a Samurai and then answer the question.
The strangers leaped out of their boats and pulled them up on the small beach. By signs, they made it clear the castaways should climb aboard.
The fishermen exchanged frightened glances and whispered to one another,
“What about Denzo and Jusuke?”
Gesturing, Manjiro communicated to the strangers about the two men in the cave. Denzo and Jusuke were retrieved, both of them so weak they had to be carried to the boats. Everyone found a place and the sailors shoved off. The two boats rowed away from the island toward an unknown future.
The sun flickered on the restless waves just as it always did. The wind blew just as steadily as it always had. Yet everything had changed. They had been rescued from the island, only to be taken captive by barbarians.
Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking.
What do the details in this excerpt help readers to infer about the barbarians?
A. They are just as mean and monstrous as the fishermen expect them to be.
B. They are suspicious creatures who seem to be from a place other than Earth.
C. They have a plan to humiliate the fishermen and are waiting for the right time.
D. They are just as curious about the fishermen as the fishermen are about them.
Answer:
D
Step-by-step explanation:
"Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking."
"The fishermen exchanged frightened glances and whispered to one another,"

If 11 yards of carpet weighs 240 pounds, which formula can be used to determine x, how much 17 yards of carpet weighs?
Answer:
cross multiplication
Step-by-step explanation:
[tex]\frac{11}{240}[/tex] x [tex]\frac{17}{x}[/tex]
[yards/weight x yards/unknown weight]
11x = 4080
x = 370.9 or 371 pounds

Which expressions are equal to
23 ?
Answer: The first option and the third option
Step-by-step explanation: You are not supposed to find something equivalent to the fraction, you have to divide the fraction.
13824 ÷ 8 = 1728
Then it is when you try to find a number equivalent to 1728. 12 to the power of 3 equals 1728
12×12=144
144×12=1728
12 to the power of 3 is equivalent to 1728
These are wrong: 2 to the power of three is unequivalent and so is 12 to the power of 6 and 6 to the power of 3
2 to the power of 6 is 64
2×2=4
4×2=8
8×2=16
16×2=32
32×2=64
3 to the power of 3 is 27
3×3=9
9×3=27
64 times 27 equals 1728 so it's equivalent and that means that our answers are A, the 1st option , and C, the 3rd option
The equivalent expression will be;
⇒ 12³
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 6³ × 2⁶ / 2³
Now,
Since, The expression is,
⇒ 6³ × 2⁶ / 2³
Solve as;
⇒ 6³ × 2⁶ × 2⁻³
⇒ 6³ × 2⁶⁻³
⇒ 6³ × 2³
⇒ (6 × 2)³
⇒ 12³
Thus, We get;
⇒ 6³ × 2⁶ / 2³ = 12³

what is 0.45 divide by 0.3 please show work.
Step-by-step explanation:
We can use standard form to make it simpler to deal with.
0.45=45×10^-2
0.3=3×10^-1
Now 45÷3=15
10^-2÷10^-1=10^-1
So the answer is 15×10^-1 OR 1.5
State the degree and end behavior of the following polynomial f(x)=4x^3+3x^5-x^2 - 2
Answer:
Degree
Five Degree
End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.
Step-by-step explanation:
[tex]y = 4 {x}^{3} + 3 {x}^{5} - {x}^{2} - 2[/tex]
A five-degree polynomial function. Rearrange the terms.
[tex]y = 3 {x}^{5} + 4 {x}^{3} - {x}^{2} - 2[/tex]
Because it is an odd-degree function, the graph increases from negative infinity and ends by increasing at positive infinity.
Graph / End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.
Lisa needs 250 yards of yarn to knit a hat. She has 185 yards of yarn and needs to buy the rest. How many yards of yarn does she need to buy?
Use the variable y to represent the number of yards of yarn she needs to buy.
Which equation represents this situation and its solution?
250y = 185; y = 55
y + 185 = 250; y = 65
y + 250 = 185; y = 65
185y = 250; y = 55
Answer:
it's answer is y + 185 = 250; y = 65

Harrison has 40 CDs in his music collection.
If 30% of the CDs are country music and 50% are pop music, how many CDs are other types of music?
There are____ CDs that are other types of music.
Answer:
20 of the cds are pop
12 are country
That leaves 8 cds that are other types of music.
Step-by-step explanation:
Answer:
There are 8
Step-by-step explanation:
Since the percentage of pop music is 50, and there are 40 CDs, we can see that 20 are pop
if we do 40(.30) we get 12
12+20=32
40-32=8

what is 9 : 45 = 6 : ?
Answer:6:45
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
a ratio is just a fraction
9:45 = 9/45
6:x = 6/x
now you have 9/45 = 6/x
cross multiply:
9 * x = 45 * 6
9x = 270
divide both sides by 9
9x/9 = 270/9
x = 30

Answer:
101 sq. ft
Step-by-step explanation:
This shape can be divided into 4 parts (see picture). Recall that the formula for rectangles and squares is length * width.Also note that triangles are half a square, meaning if you divide the formula of a square's area by two (length* width), then you'll get the area of a triangle.Rectangle: 16 * 5 = 80 sq.ftRectangle: 6 * 2 = 12 sq.ftRectangle: 2 * 3 = 6 sq.ftTriangle: [Assume that it is a full square with a length of 2 and with of 3, then divide that by 2] (3*2)/2 = 3 sq.ft.Lastly add all your values together: 80 + 12 + 6 + 3 = 101Don't forget to add units!Answer: 101 sq. ftA student usually save $20 a month.He would like reach a goal $350 in 12 months

Carla and Andrew have 29 chocolate chip cookies. Andrew has 8 more than twice Carla’s cookies. How many cookies does each person have?
Step-by-step explanation:
29 cookies
Carla has X cookies
Andrew has 8+ 2X cookies
x + 8 + 2x = 29
3x = 29-8
3x= 21
x = 7 / Carla has 7 cookies
8+ 2x = 8+2•7= 8+14=22 / Andrew has 22 cookies
