Answer:
V=[tex]\frac{28\pi }{3}[/tex]
Step-by-step explanation:
Plug and chug into the formula, your radius is 2ft, and your height is 7ft.
[tex]V=\pi*2^{2} *\frac{7}{3}[/tex]
V=[tex]\frac{28\pi }{3}[/tex] or 29.30 if [tex]\pi =3.14[/tex]
During a building project, a brick is
dropped from a height of 1,936 ft. If the
equation for height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the brick to
hit the ground?
[?] seconds
Answer:
11 seconds
Step-by-step explanation:
h(t) = -16t^2 + 1936
When the brick hits the ground h = 0 so:
-16t^2 + 1936 = 0
-16t^2 = -1936
t^2 = -1936/-16
= 121
t = 11 seconds.
The amount of time taken by the brick to hit the ground is 11 seconds.
What is a function?A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
It is given that during a building project, a brick is dropped from a height of 1,936 ft. If the equation for height as a function of time is h(t) = -16t² + initial height. where t is time in seconds and h(t) is height in feet.
h(t) = -16t² + 1936
When the brick hits the ground h = 0 then the amount of time taken by the brick will be calculated as below:-
-16t² + 1936 = 0
-16t² = -1936
t² = -1936/-16
t²= 121
t = 11 seconds.
Therefore, the amount of time taken by the brick to hit the ground is 11 seconds.

The width of a picnic table is 3 times its length. If the length is 5/6 yd long, what is the area of the picnic table in square feet?
Step-by-step explanation:
Breadth
=5/6
Length
=15/6
Area of rectangle = l x b
=5/6 x 15/6
=75/6
Answer:
6 1/4 sq ft
Step-by-step explanation:
x = length = 5/6
y = width = 3x
so y = 3(5/6) or 15/6
A = length · width
A = 5/6 · 15.6 or 25/12 which is 6 1/4

In a recent year, a hospital had 4310 births. Find the mean number of births per day, then use that result and the Poisson Distribution to find the probability that in a day there are 13 births.
Answer:
11.8 ;
0.1036360
Step-by-step explanation:
Mean births per day, μ = number of births per year / number of days in a year ;
4310 / 365 = 11. 8 births per day
From poisson distribution :
P(x) = (μ^x * e^-μ) ÷ x!
P(x = 13) = (11.8^13 * e^-11.8) ÷ 13!
P(x = 13) = 6.453438E8 / 13!
P(x = 13) = 0.1036360
Write an equation for the relationship between x and y.

Directions:Find the measures of the missing angles in each trapezoid. Will give brainliest for full answer.Posted for the 4th time :(
Step-by-step explanation:
m<M=m<L=110°
m<N=m<O=x → 2x+2(110°)=360° → x=70°
m<E=180°-22°=158°
m<A=360°-(88°+22°+158°)= 92°
m<D=m<O=61°
m<S=m<G=x → 2x+2(61°)=360° → x=238/2 = 119°
Answer:
Step-by-step explanation:
1)∠L + ∠O = 180 {Co interior angles}
110 + ∠O = 180
∠O = 180 - 110
∠O = 70
Base angles of isosceles trapezoid are equal
∠M = ∠L
∠M = 110
∠O = ∠N
∠N = 70
2) ∠c + ∠A = 180 {Co interior angles}
88 + ∠A = 180
∠A = 180 -88
∠A = 92
∠D + ∠E = 180 {Co interior angles}
22 +∠E = 180
∠E = 180 - 22
∠E = 158
3) ∠O + ∠G = 180 {Co interior angles}
61 + ∠G = 180
∠G = 180 - 61
∠G = 119
Base angles of isosceles trapezoid are equal
∠D = ∠O
∠D = 61
∠S = ∠G
∠S = 119
Ariana compró cierto número de sacos de azúcar por S/. 675 y luego los vendió por S/. 1 080, ganando S/. 3 por cada saco. ¿Cuántos sacos de azúcar compró?
Responder:
135
Explicación paso a paso:
Número de bolsas compradas = x
Costo total de compra = 675
Costo total de ventas = 1080
Beneficio por bolsa = 3
Por eso :
Beneficio total + costo total de compra = costo total de ventas
3x + 675 = 1080
3x = 1080 - 675
3 veces = 405
x = 405/3
x = 135
Se compraron 135 bolsas

Last week, Thomas ran 5 1/4 miles. This week, he planes to run 1/2 as far as he ran last week. How many miles does Thomas plan to run this week?
Answer:
2.625
Step-by-step explanation:
Last week Thomas ran 5 1/4 miles
This week he plans to run 1/2 miles as far
Therefore the number of miles he plans to run cann be calculated as follows
= 5 1/4 × 1/2
= 21/4 × 1/2
= 21/8
= 2.625
Hence Thomas plans to run 2.625 miles

11) D. $3012) Two answers: choice C, choice D13) A. Subtract 100 from each side14) A. n = 9 and n = -5====================================================
Explanation:
11) We set p(120-4p) equal to zero to find that p = 0 is one solution and 120-4p = 0 leads to p = 30. The prices of $0 and $30 both lead to $0 in revenue. It sounds like your teacher wants the larger price value.12) We set each of the two revenue expressions equal to 600.13) Replace the (n-2)^2 with another variable. Let's call that x. So we have the equation 100+x = 149, which is the same as x+100 = 149. We subtract 100 from both sides to undo the +100.14) After following the steps in problem 13, you should have (n-2)^2 = 49, which then becomes n-2 = 7 or n-2 = -7 after applying the square root to both sides. Those two equations solve to n = 9 and n = -5 in that order.Leon got a reduction of $40 on a Geometry set
