A concrete pillar has the shape of a cylinder. It has a diameter of 8 m and a height of 9 m. If concrete cost $87 per cubic meter, how much did the concrete cost for the pillar? Use 3.14 for pi and do not round your answer
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.
19.If V= V + at, then a=
Answer:
[tex]a=\frac{V-V_{0}}{t}[/tex]
Step-by-step explanation:
[tex]V = V_{0}+at[/tex] (given)
[tex]at = V-V_{0}[/tex] (minus [tex]V_{0}[/tex] on both sides)
[tex]a = \frac{V-V_{0}}{t}[/tex] (divide [tex]t[/tex] on both sides)
Hope this helps :)

If a point is originally located at (2,9) and is translated 4 units to the right and 7 units up, what would its new
coordinates be?
Given:
The point is (2,9).
It is translated 4 units to the right and 7 units up.
To find:
The coordinates of new point.
Solution:
The point is translated 4 units to the right and 7 units up. So, the rule of translation is
[tex](x,y)\to (x+4,y+7)[/tex]
The point is (2,9). Using the above rule, we get
[tex](2,9)\to (2+4,9+7)[/tex]
[tex](2,9)\to (6,16)[/tex]
Therefore, the coordinates of new points are (6,16).

Olivia is a stockbroker. She makes 4% of her sales in commission. Last week, she sold $7,200 worth of stocks.
a. How much commission did she make last week?
b. If she were to average the same commission each week, how much would she make in commission in a year, treating a year as having exactly 52 weeks.
Answer:
i think a is 6912:)
i thin b is 359424:)
Step-by-step explanation:
i'm so sorry if it's wrong <3
The answers for the given problem are as (a) the commission made by Olivia in a week is $288 and (b) the total commission for a year is $14976.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The price of stocks sold = $7200.
The commission percentage = 4%.
(a) The commission made by Olivia per week is found as,
4% of 7200
= 4/100 × 7200
= 288
(b) Considering 52 weeks in a year, the commission made by her in a week is given as,
52 × 288
= 14976
Hence, the commision made by her in a week is $288 and the total commission for a year is $14976.

what is y intercept?
Answer:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

Ben was holding a bake sale to raise money for his field trip. He sold cookies for $2 each, muffins for $1 each, and lemonade for $4 a bottle. If he sold 24 cookies, 13 muffins, and 36 bottles of lemonade, how much money did he raise for his field trip? Explain how you found your answer.
Answer: he raised $205
Step-by-step explanation:
cookies: $48 (24x2)
muffins: $13 (13x1)
lemonade: 144 (36x4)
144+13+4=$205
Answer:
205
Step-by-step explanation:
COOKIES: 2x24= 48
MUFFINS: 1x13= 13
LEMONADE: 4x36= 144
144+ 48+ 13= 205
written answer:
The answer is 244 i got this answer by mulitplying how much he sold by the prices he sold by.So i multiplied 2x24 for the cookies and got 48, then i multiplied the muffins 1x13 to get 13.Finally i multiplied 4x36 to get 144 after that, i added all the sums up and i got the answer 205. So Ben raised $205 for his feild trip.
[50 pts] An even number, n, times the next consecutive number, n + 2, is equal to 168. Find the original number.
We are given:
An even number 'n', multiplied by the next consecutive even number is 168
Solving for n:
From the given statement, we can say that:
n(n+2) = 168 [n multiplied by the next even number 'n+2']
n² + 2n = 168
n² + 2n - 168 = 0 [subtracting 168 from both sides]
We can see that we now have a quadratic equation, solving using splitting the middle term
n² + 14n - 12n - 168 = 0
n(n + 14) -12(n + 14) = 0 [factoring out common terms]
(n-12)(n+14) = 0
Here, we can divide both sides by either (n-12) OR (n+14)
Checking the result in both the cases:
(n + 14) = 0/(n-12) (n-12) = 0/(n+14)
n + 14 = 0 n - 12 = 0
n = -14 n = 12
Both these values are even and since we are not told if the number 'n' is positive or negative, both 12 and -14 are the possible values of n

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?
Answer:
72.1 hours
Step-by-step explanation:
Let the number of hours be represented as: x
Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.
Convert 2 7/8 pounds to decimal = 2.875pounds
Hence:
252 - 2.875x
Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.
Convert 3 1/3 pounds to decimal = 3.333 pounds
Hence:
285 - 3.333x
How many hours until they have the same amount of fruit left?
This calculated by equating both equation together
252 - 2.875x = 285 - 3.333x
Collect like terms
-2.875x + 3.333x = 285 - 252
0.458x = 33
x = 33 / 0.458
x = 72.052401747 hours
x ≈ 72.1 hours
They would have the same amount of fruit left after 72.1 hours

Solve for p.
7/p = 8/9
Answer: p = 63/8
Step-by-step explanation:
first, we determine the defined range.
7/p = 8/9, p is not equal to 0.
then, we cross multiply.
63 = 8p
then, we divide both sides.
p = 63/8
Part A: The x-intercepts of the graph are (-2, 0) and (2.5, 0). 2x² - x - 10 = 0 2x² - 5x + 4x - 10 = 0 x(2x - 5) + 2(2x - 5) = 0 (x + 2)(2x - 5) = 0 x = -2, 5/2 or 2.5 Part B: The vertex is going to be the minimum of the function. The coordinates are (0.25, -10.125). Vertex = (h,k) h = midpoint of the x-intercepts (because of symmetry) h = (-2 + 5/2) = 1/4 k = f(1/4) k = 2(1/4)² - 1/4 - 10 = -81/8 Vertex: (0.25, -10.125). y-intercept: when x = 0 2(0)² - 0 - 10 = -10 Part C: To graph f(x), I would draw a line connecting the x-intercepts, vertex and the y-intercept using the points (-2,0), (0,-10), (0.25, -10.125) and (2.5,0). These points are the answers from part A and B and that is why I can use them to draw the graph.
