Answer:
It will cost $39,337.92 for the piller.
Step-by-step explanation:
Given that,
The diameter of the cylinder, d = 8 m
Height of the cylinder, h = 9 m
If concrete cost $87 per cubic meter, we need to find how much the concrete cost for the pillar.
The volume of the cylinder is given by :
[tex]V=\pi r^2h\\\\=3.14\times (4)^2\times 9\\\\=452.16\ m^3[/tex]
Cost per cubic meter = $87
Cost for 452.16 m³ will be :
C = 452.16 × 87
C = $39,337.92
Hence, it will cost $39,337.92 for the piller.
What is 288889 divide by 676767 please help
Answer:
0.42686626268 yeah that it
solve:3x-8y=-33
solve:9x+8y=29
show work please
Answer:
for the first one: x = -25/3 or -8.333333
for the second one: x = 29-8y/9
Step-by-step explanation:
for the first one:
add 8 to both sides 3x=-33 + 8
simplify -33+8 to -25
divide both sides by 3
which gives you -25/3 or 8.333333
for the second one:
subtract 8y from both sides 9x=29-8y
divide both sides by 9
which gives you x= 29-8y/9

how do I solve -12+1/2x=-6
Answer:
x = 12
Step-by-step explanation:
First, eliminate the fractional coefficient 1/2, by multiplying all three terms by 2:
-24 + x = -12
Adding 24 to both sides isolates x: x = -12 + 24, or x = 12

Answer: 5
Step-by-step explanation: 6-1=5
Answer:
x=5
Step-by-step explanation:
To get the x alone, you would have to get the one away. To do that, you will have to get it to 0, by subtracting 1 from 6, making it five. Now x is alone like this: x=5

The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
Select all ordered pairs that could be used to show that this claim is incorrect.
(–9, –6)
(1, 12)
(–10, –10)
(4, 7)
(–5, 1)
Given:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
To find:
All the ordered pairs that could be used to show that this claim is incorrect.
Solution:
We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.
A relation is called function if there exist a unique output for each input.
If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.
If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.
If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.
Therefore, the correct options are (a), (b) and (e).

A souvenir shop sells two sizes of American flags. Small flags cost $3.50 and large flags cost $6.50. On a recent day, 155 flags were sold and $683.50 was collected. How many flags of each size were sold that day?
Answer:
Small flags = 108
large flags= 47
Step-by-step explanation:
Step one:
given
let the number of small lag be x
and big flags be y
so
3.5x+6.5y= 683.5----------1
x+y=155------------------------2
Step two:
from eqn 2 x= 155-y
put x= 155-y in eqn 1
3.5(155-y)+6.5y= 683.5
542.5-3.5y+6.5y=683.5
collect like terms
3y=141
divide by 3
y= 141/3
y=47
Step three:
put y= 47 in eqn 2
x+47=155
x= 155-47
x=108

Solve for x: 90 - 3/2x < 30.
a.) >-20
b.) >-40
c.) x<-40
d.)<-20
all the < or > have a line under them
Answer:
The answer would be C, hope i helped
Step-by-step explanation:
First you have to get x by itself. So you do 90-90= 0 and 30-90= -60 which gets:
90 - 3/2x < 30 to -3/2x < -60
Then, you do -3/2 - (-3/2)= 0 and do the same to -60. -60 - (-3/2) = -58.5
which makes it look like
X = -58.5
-58.5 is a smaller number than -40 which means, when you fill it in for x it works
-58.5 ≤ -40

Answer:
4/9ths of a cup of sugar is needed for one cup of flour.
Step-by-step explanation:
To answer this you need to scale the number of cups of flour up from 3/4 to 1 that ratio would be 4/3 (multiplying a fraction by its own reciprocal will give you 1).
We can then simply take that ratio, and scale the sugar by the same amount:
1/3 * 4/3 = 4/9
Write a system of equations to describe the situation below, solve, and write as an ordered pair (with number of months as x).
Two friends, Ann and Malia, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Ann's hair is already 23 centimeters long and grows at a constant rate of 3 centimeters per month. Malia's hair is 27 centimeters and growing at a speed of 1 centimeter per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?

Ann's hair length: y = 23 + 3x
Malia's hair length: y = 27 + x
Thus: 23 + 3x = 27 + x
23 + 2x = 27
2x = 4
x = 2
Ann's hair length: y = 23 + 2(3) = 29
Malia's Hair length: y = 27 + 2 = 29
Solution: (x, y) = (2, 29)
In 2 months both Ann's and Malia's hair will be 29 centimeters long.

Let's start with Ann's hair: 23 centimeters + 3 centimeters per month
Malia's hair: 27 centimeters + 1 centimeter per month
Now we can substitute the number of months for "x"
Ann's hair length = 23 + 3x
Malia's hair length = 27 +1x
We know that we want both girls to have the same hair length at the end so we can set these two equations as equal to each other:
23 + 3x = 27 + 1x Subtract 23 from both sides
3x = 4 + 1x Subtract 1x from both sides
2x = 4 Divide by 2
x=2 Now we know it will take 2 months for their hair to be the same length!
Let's plug that in to our original equations:
Ann's hair length = 23 + 3(2) = 29 centimeters
Malia's hair = 27 + 1(2) = 29 centimeters
It will take 2 months for the girls to grow their hair to the same length of 29 centimeters.
As ordered pairs, with x as the number of months, we can use the length of the girls hair as the y value.
At 0 months, Ann's hair is 23 cm and Malia's is 27 cm so the first ordered pairs are (0, 23) and (0, 27).
At 1 month, Ann's hair grows 3 cm and Malia's grows 1 cm so the second pairs are (1, 26) and (1, 28).
Finally, at 2 months Ann's hair is at 29 cm and so is Malia's so the final ordered pair is (2, 29) for both girls.
If you were to draw these equations on a graph, (2, 29) is where the lines would intersect.
