Answer:
Step-by-step explanation:
V, r, h are the volume, radius, and height, respectively.
V = πr²h = 9πr²
The only error in your previous answers was that you forgot the π.
if r = 1, V = 9π1² = 9π ≅ 28 in³
if r = 2, V = 9π2² = 36π ≅ 113 in³
if r = 3, V = 9π3² = 81π ≅ 254 in³

Answer:
[tex] \frac{1}{9} [/tex]
Step-by-step explanation:
We can multiply all exponents together
[tex] - \frac{3}{4} \times \frac{1}{3} \times 2[/tex]
-1/2
We then do
[tex] {81}^{ - 1 \div 2} [/tex]
Which is

Answer:
x - 4
Step-by-step explanation:
The volume V is calculated as
V = lbh
Given 2 of the dimensions
(x - 1)(x - 3) = x² - 4x + 3
Then the third dimension is found by dividing V(x) by x² - 4x + 3
Using long division
x - 4
-----------------------------------------
x² - 4x + 3 | x³ - 8x² + 19x - 12
x³ - 4x² + 3x
-------------------------------------
- 4x² + 16x - 12
- 4x² + 16x - 12
--------------------------------------
0 ← remainder
Thus quotient = x - 4
That is the missing dimension is x - 4

Pls help i rlly need to get my grades up !! The graph below shows a proportional relationship between x and y.
What is the constant of proportionality,
y/x
======================================================
Explanation:
We can pick any (x,y) point on this blue line as long as we don't pick (0,0)
This is because we cannot divide by zero.
Let's say we pick the point (x,y) = (1,4)
The constant of proportionality is found like so
k = y/x
k = 4/1
k = 4
The constant of proportionality is 4
Or we could pick a point like (2,8) to get
k = y/x
k = 8/2
k = 4
We get the same thing.
There are infinitely many points to pick, but in my opinion, it's easiest to stick with (1,4).
As a slight alternative, you can apply the slope formula (pick any two points you want on the blue line) and you should get 4 as well.
-----------------
Extra info:
The direct proportion equation always goes through the origin. This means the y intercept is 0. The slope is equal to the constant of proportionality. The equation of this line is y = 4xAnswer:
y/x = 4Step-by-step explanation:
For any point from line for 1 of x we have 4 ys:
x=1→y=4, x=2→y=8=4×2, x=7→y=28=4×7
It means:
y = 4x dividing by x we get: y/x = 4
Find the value of x.
Answer:
x = 3Step-by-step explanation:
5x + 4 = 0.5×38
5x + 4 = 19
5x = 19 - 4
5x = 15
x = 3

- The local museum requires 2 adult
chaperones for every 15 students. How
many adults would be needed with
90 students?
Answer:
For 90 students, 12 adult chaperones are required.
Step-by-step explanation:
90 (students) divided by 15 gives us a proportion to multiple the amount of adults by.
90/15 = 6
Since there are 6 times as many students as the question provided, we will multiply the amount of adults in the question by 6.
2 x 6 = 12
Animal Nutrition Kevin's dog Amadeus likes two kinds of canned dog food. Gourmet Dog costs 40 cents a can and
has 20 units of a vitamin complex; the calorie content is 75 calories. Chow Hound costs 32 cents a can and has 35 units of vitamins and 50 calories. Kevin likes Amadeus to have at least 1175 units of vitamins a month and at least
2375 calories during the same time period. Kevin has space to store only 60 cans of dog food at a time. How much of each kind of dog food should Kevin buy each month to minimize his cost?
Answer:
The answer should be 15 cans GD and 25 cans CH

What is the area of this?
[tex]area = lw \\ area = (7.5)(6) \\ area = 45 {feet}^{2} [/tex]
[tex]area = \frac{1}{2} bh \\ area = \frac{1}{2} (6)(4) \\ area = \frac{1}{2} (24) \\ area = 12 {feet}^{2} [/tex]
total area = 45 + 12
total area = 57 feet²

Which fraction can be replaced with 1 2 when estimating with fractions? A. 10 12 B. 7 16 C. 2 9 D. 1 8
Answer:
B. 7/16
Step-by-step explanation:
The answer to this question is the option whose value is closest to 1/2.
We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5
10/12 = 0.833
7/16 = 0.43
2/9 = 0.222
1/8 = 0.125
The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.

Matt starts swimming lessons on 5 day . He goes every 10 days . How many lessons will Matt go to in 30 days?
Answer: 3 lessons
Step-by-step explanation:
Matt starts swimming lessons on Day 5.
He then goes to swimming lessons every 10 days. The dates he went on lessons are therefore:
First lesson = Day 5
Second lesson = Day 5 + 10 days = Day 15
Third lesson = Day 15 + 10 days = Day 25
Fourth lesson = Day 25 + 10 days= Day 35
He therefore only went for 3 lessons because the 4th lesson was after Day 30.
Jeremy is 12 4 5 years old. Carl is 1 1 6 years younger than Jeremy and Jane is 1 1 3 years younger than Carl. How old is Jane?
Answer: Jane is 10 9/30 years old
Step-by-step explanation:
Given that Jeremy is 12 4 /5 years old
Carl is 1 1/6 years younger than Jeremy which is why we would subtract giving us
=12 4/5 - 1 1/6
= 11 (24- 5)/30
= 11 19/30 years
and Jane is 1 1 3 years younger than Carl which is why we would subtract giving us
=11 19/30 - 1 1/3
= 10 ( 19 - 10)/ 30
=10 9/30 years
Ellen's living room is 3 meters wide and 8 meters long. She wants to install pink carpet that costs $9.00 per square meter. How much will it cost to buy enough carpet for the living room?
Answer:
$216
Step-by-step explanation:
................
Area of room =(l*b)
=(3*8)m²= 24m²
