Answer:
36 9/16 ft^3
Step-by-step explanation:
volume = length * width * height
volume = 3 3/4 ft * 3 ft * 3 1/4 ft
Change all mixed numerals to fractions.
volume = 15/4 * 3/1 * 13/4 ft^3
volume = 585/16 ft^3
volume = 36 9/16 ft^3
if PN=29cm and MN=13 , then PM=?
*see attachment for the figure referred to
Answer/Step-by-step explanation:
1. PN = 29
MN = 13
PM = ?
[tex] PN = PM + MN [/tex] (Segment addition postulate)
[tex] PN - MN = PM [/tex] (subtract MN from each side)
[tex] 29 - 13 = PM [/tex] (substitute)
[tex] 16 = PM [/tex]
[tex] PM = 16 cm [/tex]
2. PN = 34, MN = 19, PM = ?
[tex] PN = PM + MN [/tex] (sediment addition postulate)
[tex] PN - MN = PM [/tex] (subtract MN from each side)
[tex] 34 - 19 = PM [/tex] (substitute)
[tex] 15 = PM [/tex]
[tex] PM = 15 cm [/tex]
3. PM = 19, MN = 23, PN = ?
[tex] PN = PM + MN [/tex] (Segment addition postulate)
[tex] PN = 19 + 23 [/tex] (substitute)
[tex] PN = 42 cm [/tex]
4. MN = 82, PN = 105, PM = ?
[tex] PN = PM + MN [/tex] (segment addition postulate)
[tex] PN - MN = PM [/tex] (subtract MN from each side)
[tex] 105 - 82 = PM [/tex] (substitute)
[tex] 23 = PM [/tex]
[tex] PM = 23 cm [/tex]
5. PM = 100, MN = 100, PN = ?
[tex] PN = PM + MN [/tex] (Segment addition postulate)
[tex] PN = 100 + 100 [/tex] (substitute)
[tex] PN = 200 cm [/tex]
Three electrons are removed from each of 4 atoms. Write an expression to represent the net change on the charge for the group of atoms.

Explain in detail with at least two sentences how to represent the product of A and B geometrically given that A=15 + 56i and B = 7 + 4i. Give the coordinate of A • B in polar form.
Answer:
Basically each part of the first complex number gets multiplied by each part of the second complex number. You are multiplying 2 binomials.
(15 + 56i(7 + 4i)
= 105 + 60i + 392i + 224i^2
= 105 + 452i - 224 ( because i^2 = -1)

A group of 6 students is surveying their classmates to get feedback about different clubs they're involved in. If each surveys more than 2 of their classmates, the total number of completed surveys, s(x), is given by the equation s(x)=6x. What could be the domain of this function?
Answer:
The domain would be given by D = {X ≥ 2} X = [2, Z]. Since the variable Z is the number of children in the school. And the 6 children should not survey the same person, it would be Z / 6 for each interviewer.
Step-by-step explanation:
- If the group of children surveys more than 2 classmates, it means that the number with which the survey begins is 12 students.
And since the maximum number of students in the school is given by the variable of Z, then Z is the number with which the domain closes.
The rank would be given by the set of [2, Z]
Z / 6 being the maximum number of children surveyed by 1 interviewer.
The Domain of given function is, [tex]x\geq 2[/tex]
The Domain of function is defined as, all input values for which function is defined.
The total number of completed survey is given by a function,
[tex]s(x)=6x[/tex]
Since, If the group of children surveys more than 2 classmates, it means that the number with which the survey begins is 12 students.
It means value of x is always greater and equal to 2.
So that, [tex]x\geq 2[/tex]

Samuel was riding in the back seat of the station wagon on the way home after a long and tiring day at the
beach. He fell asleep halfway home. He didn't wake up until he still had half as far to go as he had already
gone while asleep. How much of the entire trip home was Samuel asleep?
Help with diagram please
Answer:
Samuel slept for 1/4 of the distance.
Step-by-step explanation:
The information provided are:
Samuel fell asleep halfway home.He didn't wake up until he still had half as far to go as he had already gone while asleep.Consider that the total distance covered was 1.
Then from the first point we know that Samuel fell asleep after covering a distance of 1/2.
It is provided that he woke up only after covering half of the remaining distance.
That is, he slept for 1/4 of the remaining distance.
Thus, Samuel was asleep for 1/4th of the entire trip home.
The points P, Q, R and S all lie on the same line segment, in that order, such that the ratio of PQ : QR: RS is equal to 4:2:1. If PS = 14, find PR.

ratio
4:2:1
PS = 14
add the ration = 4 + 2 + 1 = 7
14 / 7 = 2
PQ at 4 x 2 = 8
QR at 2 x 2 = 4
RS at 1 x 2 = 2
------------

PR = PQ + QR
PR = 8 + 4
PR = 12
The length of the line segment PR is 12 units.
What is a line segment ?A line segment is a subset of a line which has two endpoints.
According to the given question The points P, Q, R and S all lie on the same line segment PS and the ratio of PQ : QR: RS is equal to 4:2:1.
Assuming PQ = 4x, QR = 2x and RS = x.
We know PQ + QR + RS = PS.
∴ 4x + 2x + x = 14.
7x = 14.
x = 2.
PR = PQ + QR.
PR = 4(2) + 2(2).
PR = 8 + 4.

One number is two less than three times another. If their sum is decreased by two, the result is four. Find the numbers.
The smaller of the numbers is ___ and the larger is ___
Answer: The smaller of the numbers is 2 and the larger is 4.
Step-by-step explanation: 2x3-2=4. 2+4-2=4
Answer:
The bigger number is 1 and the smaller number is also 1
Step-by-step explanation:
One number is 2 less than 3 times another
x + 2 = 3y
If their sum is decreased by 2 the result is 4
(x + 2 + 3y) - 2 = 4
x + 3y = 4
x = 4 - 3y
Substituting value of x, 4 - 3y , in x + 2 = 3y
4 - 3y + 2 = 3y
6 - 3y = 3y
6 = 3y + 3y
6 = 6y
Divide both sides by coefficient of y, 6
y = 1
Substituting value of y, 1 in x + 2 = 3y
x + 2 = 3(1)
x + 2 = 3
x = 3 - 2
x = 1
Find the inverse of y = x^2+5

Sebastian has a bag of 15 blue marbles, 18 red marbles, and 12 yellow marbles. He reaches into the bag three times and pulls out 2 red marbles and a blue marble. What is the probability that he reaches into the bag and pulls out a yellow marble next? A. 1/4 B. 8/21 C. 2/7 D. 5/14
===================================================
Explanation:
Initially there are 15+18+12 = 45 marbles total. He selects 3 marbles (2 reds, 1 blue).
Assuming he doesn't put the three marbles back, this means there are now 45-3 = 42 marbles overall. The yellow count hasn't changed since the first three marbles do not involve yellow. We have 12 yellow out of 42 which leads to the fraction 12/42 to represent the probability of getting yellow.
Reduce 12/42 to get 2/7. You divide both parts by the GCF 6.
-------
Side note: if he did put the marbles back, then the probability of getting yellow would be 12/45 = 4/15

Jorge reasons that the next letter in the sequence is M, since three letters of the alphabet are skipped between each listed. Which explains whether Marcy should agree with Jorge's inductive reasoning.
Complete question is;
Consider the sequence shown: A, E, I … Jorge reasons that the next letter in the sequence is M, since three letters of the alphabet are skipped between each listed letter. Which explains whether Marcy should agree with Jorge’s inductive reasoning?
A. No; the sequence could be listing the vowels in alphabetical order.
B. No; sequences with only three terms are too short to use to find patterns.
C. Yes; this is the only reasonable pattern that can be identified from the terms.
D. Yes; inductive reasoning is a valid method for determining terms of a sequence
Answer:
Options C and D are the correct reasons why Marcy should agree with Jorge.
Step-by-step explanation:
A) It's wrong because the alphabets don't have to be listed in alphabetical order.
B) It's wrong because sequence can take any form. It could be 2 terms used to find patterns. It does not matter.
C) This is correct because after letter A, the next 3 letters which are B, C, D were skipped before E. Also, after E, the next 3 letters were skipped which are E, F, G before I. Thus, it's the only reasonable pattern from the terms to find the next term.
D) Inductive reasoning is based on observing patterns in a sequence, which we can use to decide the next successive terms of such a sequence. Thus, this is true because inductive reasoning is a valid method.

Answer:
943,281
Step-by-step explanation:
Just move the 3 up a value
If it's in the ten's place, then move it to the hundred's place value.
If it's in the hundred's place, then move it to thousand's place value.
So on and so on...
The number is 943,281.
What is place value?Place value is the value of each digit in a number. The value of every digit in a number is different based upon its position. A number might have two similar digits but different values, which is decided by the position that the digit holds in the number.
Place value is the value of a digit according to its position in the number such as ones, tens, hundreds, and so on.
For example, the place value of 5 in 3458 is 5 tens, or 50. However, the place value of 5 in 5781 is expressed as 5 thousands or 5,000.
Given:
digit 3 is 10 times as much as the value of the digit 3 in 942381
Here the digit 3 is at hundred place value.
Then, after 10 times the place value be at thousand.
hence, the number would be 943,281.

Note that we have used these steps to solve the equation, find the value of x that makes it true. We could use different steps to rewrite the equation to almost anything you want:
7x -3 -95 = -17 -95 ⇒ 7x -98 = -112 . . . . . subtract 95 from both sides
12(7x -98) = 12(-112) ⇒ 84x -1176 = -1344 . . . . multiply both sides by 12
