Answer:
A) Volume of one block = 27n³ cm³
Volume of the box = 216n⁹ cm³
B) 8n⁶ blocks will fit in one box.
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cube}\\\\$V=s^3$\\\\where:\\ \phantom{ww}$\bullet$ $V$ is the volume. \\\phantom{ww}$\bullet$ $s$ is the side length.\\\end{minipage}}[/tex]
Part AThe side length of the cube-shaped block is 3n cm.
Substitute the given side length into the formula to find the volume of the block:
[tex]\begin{aligned}\implies \textsf{Volume of one block}&=(3n)^3\\&=3^3 \cdot n^3\\&=27n^3\;\sf cm^3\end{aligned}[/tex]
The side length of the cube-shaped box is 6n³ cm.
Substitute the given side length into the formula to find the volume of the box:
[tex]\begin{aligned}\implies \textsf{Volume of one box}&=(6n^3)^3\\&=6^3 \cdot (n^3)^3\\&=216n^9\; \sf cm^3\end{aligned}[/tex]
Part BTo find the number of blocks that will fit in the box, divide the volume of the box by the volume of one block:
[tex]\begin{aligned}\implies \textsf{Number of blocks}&=\dfrac{\textsf{Volume of box}}{\textsf{Volume of block}}\\\\& = \dfrac{216n^9}{27n^3}\\\\&=\dfrac{216}{27} \cdot \dfrac{n^9}{n^3}\\\\&=8 \cdot n^{9-3}\\\\&=8n^6\end{aligned}[/tex]

a political candidate has asked you to conduct a poll to determine what percentage of people support her. a) suppose the candidate believes that the percentage that support her is approximately 73%. if we want a 6% margin of error at a 94% confidence level, what size sample is needed?
The sample size needed will be equal to n = 149.
The (1 - α)% confidence interval for population proportion is given by
CI = p ± z(α/2)√p (1 - p)/n
The margin of error will be given as
MOE = z(α/2)√p (1 - p)/n
We know that approximately 73% people support the candidate and margin of error is 0.06.
The critical value of z for confidence level 94% is given by z = 1.65. Now, using the formula of Margin of Error.
MOE = z(α/2)√p (1 - p)/n
n = [z(α/2)√p (1 - p)/MOE]²
n = [1.65√0.73 (1 - 0.73)/0.06]²

The sum of an integer and 6 times the next consecutive odd integer is 61. Find the
value of the lesser integer.
If the sum of an integer and 6 times the next consecutive integer is 61, the the value of lesser integer is 7
Consider the first odd integer as x
Then the next consecutive odd integer = x+2
The 6 times the second integer= 6(x+2)
= 6x+12
Sum of an integer and 6 times the next consecutive odd integer is 61
Then the equation will be
x + 6x+12 = 61
Add the like terms in the equation
(1+6)x + 12 = 61
7x +12 = 61
Move 12 to the right hand side of the equation
7x = 61-12
7x = 49
x = 49/7
x = 7
The second number is
x+2 = 7+2

A recent survey showed that 73% of elementary school students have a pet. What is the ratio of students who have a pet to students who do not have a pet?
Answer:
73 : 27
Step-by-step explanation:
You want the ratio of students that have a pet to students that don't have a pet, given that 73% of students have a pet.
No petIf 73% of students have a pet, then the remaining 100% -73% = 27% of students do not have a pet.
RatioThe ratio of students who have a pet to students who don't have a pet is then ...
(have a pet) : (don't have a pet) = 73% : 27% = 73 : 27
According to a recent survey, 73% of elementary school students have a pet, making the ratio of students with pets to those without pets 73:27.
What is ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a bowl of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the total amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
You want the ratio of students that have a pet to students that don't have a pet, given that 73% of students have a pet.
If 73% of students have a pet, then the remaining 100% -73% = 27% of students do not have a pet.
The ratio of students who have a pet to students who don't have a pet is then,(have a pet) : (don't have a pet) = 73% : 27% = 73 : 27
A recent survey found that 73% of elementary school students own a pet, making the proportion of students who own pets to those who don't stand at 73:27.

Heraldo starts a push-up challenge, and on the first day does 10 pushups, the second day he does 13, the third day he does 16, and so on.
Write the recursive definition for this sequence, and then find how many pushups he should do on the 20th day, if he continues.
Answer:
Day 20 = 67 pushups (64+3)
Step-by-step explanation:
Day 1 = 10 pushups Day 2 = 13 pushups (10+3) Day 3 = 16 pushups (13+3)
He does three more pushups each day.
So day 4 = 19 pushups (16+3)
Day 5 = 22 pushups (19+3)
Day 6 = 25 pushups (22+3)
Day 7 = 28 pushups (25+3)
Day 8 = 31 pushups (28+3)
Day 9 = 34 pushups (31+3)
Day 10 = 37 pushups (34+3)
Day 11 = 40 pushups (37+3)
Day 12 = 43 pushups (40+3)
Day 13 = 46 pushups (43+3)
Day 14 = 49 pushups (46+3)
Day 15 = 52 pushups (49+3)
Day 16 = 55 pushups (52+3)
Day 17 = 58 pushups (55+3)
Day 18 = 61 pushups (58+3)
Day 19 = 64 pushups (61+3)

The perimeter of the triangle ABC is 36 cm. Then the correct option is A.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. If two triangles are similar, then the ratio of the corresponding sides will remain one.
Triangle ABC is congruent to triangle XYZ. In AABC, AB = 12 cm and AC = 14 cm. In AXYZ, YZ = 10 cm and XZ = 14 cm.
AB = XY = 12 cm
BC = YZ = 10 cm
AC = XZ = 14 cm
Then the perimeter of the triangle ABC is given as,
P = 12 + 10 + 14
P = 36 cm
The perimeter of the triangle ABC is 36 cm. Then the correct option is A.
