Answer:
we know that
volume of a grain silo=volume of a cylinder+volume of a hemisphere
volume of a grain silo=17000 ft³
volume of a cylinder=pi*r²*h
h=30 ft
volume of a cylinder=pi*r²*30----> 30*pi*r² ft³
volume of a hemisphere=(2/3)*pi*r³
so
17000=30*pi*r²+(2/3)*pi*r³-----> multiply by 3---> 51000=282.60*r²+6.28*r³
6.28*r³+282.60*r²-51000=0
using a graph tool
see the attached figure
the solution is
r=11.942 ft-------> r=11.9 ft
the answer is
The radius of the silo is 11.9 ft
i have no idea what i am doing! pls help!!!
Answer:
The first one
Step-by-step explanation:
If you are adding 15 less to 3 of n, it would be 3n-15 because 3 of n is 3n. After, you add n as well, so you get 3n-15+n. Your result is 101 so it should be on the other side of the equation.
If you subtract 13 from my number and multiply the difference by -2 , the result is -44." What is 's number
Answer:
n = 35
Step-by-step explanation:
n - 13 x -2 = -44
distribute:
(n x -2) - (13 x -2) = -44
-2n - (-26) = -44
two negatives in front of a number makes it a positive number
so rewrite -2n + 26 = -44
-2n = -44 -26
-2n = -70
n = [tex]\frac{-70}{-2}[/tex]
n = 35
calc check (35 - 13) x -2 = 22 x (-2) = -44

Find the intersection point for the following linear functions.
f(x) = 2x + 3
g(x) = -4x − 27
A. (5,-7)
B. (5,13)
C. (-5,-10)
D. (-5,-7)
Answer:
D) (-5, - 7)
Step-by-step explanation:
Because both lines intersect, they must share a point (have same x and y coordinates).
[tex]2x + 3 = - 4x - 27[/tex]
[tex]2x = - 4x - 30[/tex]
[tex]6x = - 30[/tex]
[tex]x = - 5[/tex]
Substite x for - 5 in any of the equations to find the y coordinate.
[tex]y = 2( - 5) + 3 [/tex]
[tex]y = - 10 + 3[/tex]
[tex]y = - 7[/tex]
The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)

Answer:
A
Step-by-step explanation:
what is x ?
what is y ?
Answer:
y = 100° , x = 80°
Step-by-step explanation:
Two angles on a straight line equal 180°. Therefore, 80° + y = 180°. This means y = 100°.
80° and x are alternate exterior angles. Using that property, we know those angles are congruent. This means x is also 80°.

Una tienda compra pendrive de diferentes
colores al por mayor, para navidad hizo un
pedido extraordinario de 84 memorias rojas, 196 azules y 252 verdes. Para guardar la
mercancía de forma organizada, exigió que
le enviarán las memorias en cajas iguales,
sin mezclar los colores y conteniendo el mayor número posible de memorias.
Answer:
En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.
Step-by-step explanation:
La cantidad de cajas es igual a la cantidad de memorias dividida por la capacidad de una caja. Al indicarse que las memorias serán guardadas en cajas de igual capacidad, sin mezclar los colores y con el mayor número posible de artículos, podemos utilizar el concepto de máximo común divisor, cuyo procedimiento mostramos a continuación:
(i) Realizamos la descomposición factorial de cada número:
Memorias rojas:
[tex]84 = 2\times 2 \times 3\times 7[/tex]
Memorias azules:
[tex]196 = 2\times 2\times 7\times 7[/tex]
Memorias verdes:
[tex]252 = 2\times 2\times 3 \times 3 \times 7[/tex]
(ii) Hallamos los números primos en común que tiene cada colección de memorias:
[tex]S=\{2,2,7\}[/tex]
(iii) Calculamos el máximo común divisor al multiplicar los elementos del conjunto S:
[tex]M.C.D. = 2\times 2\times 7[/tex]
[tex]M.C.D. = 28[/tex]
Esto quiere decir que cada caja debe llevar 28 memorias del mismo color. Finalmente, calculamos la cantidad requerida de cajas para cada memoria.
Memorias rojas:
[tex]n_{R} = \frac{84}{28}[/tex]
[tex]n_{R}= 3[/tex]
Memorias azules:
[tex]n_{A} = \frac{196}{28}[/tex]
[tex]n_{A} = 7[/tex]
Memorias verdes:
[tex]n_{V} = \frac{252}{28}[/tex]
[tex]n_{V} = 9[/tex]
En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.
help please. no super long answers.
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So first you have to plug in what you know...
[tex]3x+y>3\\3(\frac{3}{4})+(0)>3\\\frac{9}{4}+0>3\\\frac{9}{4} >3[/tex]
If it's hard to look at it that way you should make it look like this...
[tex]2\frac{1}{4} >3[/tex]
Now when you look at it you can tell that it's false, so [tex](\frac{3}{4},0 )[/tex] is not a solution f this inequality.
What is the measure of each angle of the hexagon? 60° 90° 120° 144°
Answer:
120
Step-by-step explanation:
A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.

Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden. What is his unit rate
Answer:
20 minutes per row
Step-by-step explanation:
Divide the total time by the total number of rows to find the amount of time for one row
6r= 120
Divide each side by 6 to isolate the variable (r= number of rows)
r= 20
A magician charges parties a $30 fee to cover travel and other expanses plus $19.99 per hour. Write an equation to represent the relationship between x, the number of hours, and y, the total charge for the magician.
Answer:
y = 19.99x + 30Step-by-step explanation:
one time charge of $30
plus $19.99 per hour
let x be the number of hour
and y be the total charge of the magician.

if 1/2 gallon of paint covers 1/12 of a wall,then how many quarts of paint are needed for the entire wall
Answer: 4
Step-by-step explanation: there is 4 quarts in a gallon so 1/2 gallon is 2 quarts. 2x2=4
Answer:
6 gallons which is 24 quarts
Step-by-step explanation:
because while covering 2/12ths of a wall you used a whole gallon of paint so if 1 gallon covers 2/12ths of a wall you have 10/12ths left and s you already used 1 so it would leave you with 5 gallons and 10 divided by 2 is 5 which would give you your answer 6 gallons and there are 4 quarts in a gallon so you would multiply 6 *4 = 24
My question is, on Sunday, 77,098 fans attended a New York Jets game. The same day, 3,397 more fans attended a New York Giants game than attended the Jets game. Altogether, how many fans attended the games? Round each number to the nearest thousand to find an estimate of how many fans attended the games.
Answer:
Total number of fan = 80,495
Step-by-step explanation:
Given:
Number of fans attended = 77,098
Additional number of fans attended = 3,397
Find:
Total number of fan
Computation:
Total number of fan = Number of fans attended + Additional number of fans attended
Total number of fan = 77,098 + 3,397
Total number of fan = 80,495
Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?
Step-by-step explanation:
A. For Tavon's gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=145-3.5x------1
for Tavon's second gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=125-3x-------------2
B. equating 1 and 2 we have
145-3.5x=125-3x
solve for x we have
145-125=-3x+3.5x
20=0.5x
divide both sides by x we have
x=20/0.5
x= 40
put x=40 in
y=145-3.5*40------1
y=145-140
y=$5
put x=40 in
y=125-3*40------1
y=125-120
y=$5
Find the exact rotation in revolutions per minute with the angular speed below:
Answer:
The exact rotation in revolutions per minute is 1.125 revolutions per minute
[tex]\omega = 1.125 \ \dfrac{Revolution}{minute}[/tex]
Step-by-step explanation:
The given angular velocity is expressed as follows;
[tex]\omega = 135 \cdot \pi \ \dfrac{rad}{h}[/tex]
Therefore, we have;
[tex]\omega = \dfrac{135 }{60} \cdot \pi \ \dfrac{rad}{minute} = \dfrac{9}{4} \cdot \pi \ \dfrac{rad}{minute} = 2.25 \cdot \pi \ \dfrac{rad}{minute}[/tex]
One (1) revolution = 2·π radian
Therefore;
π radian = 1/2 revolution
2.25·π radian = 2.25 × 1/2 revolution = 1.125 revolution
Which gives;
[tex]2.25 \cdot \pi \cdot \dfrac{rad}{minute} = 1.125 \ \dfrac{Revolution}{minute}[/tex]
The exact rotations in revolutions per minute is 1.125 revolutions per minute.
