Find the volume of a right circular cone that has a height of 2.4 in and a base with a
radius of 10.6 in. Round your answer to the nearest tenth of a cubic inch.
Answers
Answer:
282.4
Step-by-step explanation:
V=1/3 pi Bh where B is the area of the base and h is the height
V=1/3 (3.14159)(10.6)^2(2.4)=282.4
Answer:
282.4 in^3
Step-by-step explanation:π
The volume of a cone is represented by the equation [tex]v=\frac{1}{3\\}\pi r^2*h[/tex] where r is the radius of the base and h is the height. Substituting in our values for the radius and height we get:
v=1/3π*10.6^2*2.4
v=1/3*2.4*112.36*π
v=0.8*112.36*π
v=89.888*3.14
v=282.4 in^3
From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.
Answers
Answer:
0
Step-by-step explanation:
From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.
We solve the above question using the trigonometric function of Tangent
The formula is given as:
tan θ = Opposite/ Adjacent
θ = 180°
Adjacent = 80m
Opposite = Height = x
Hence,
tan 180 = x/80
Cross Multiply
x = tan 180 × 80
x = 0m
The height of the flag = 0

A bag contains 3 red marbles, 7 blue marbles and 5 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 100oth, that both
marbles drawn will be blue?
Answers
Answer:
0.218
Step-by-step explanation:
Probability is the likelihood of an event.
According to the word problem, of the 15 marbles, there are 7.
Since there are 7 blue marbles, the expected outcome of both events is 7.
The probability of the first blue marble is 7/15.
The probability of the second blue marble is 7/15.
To find the probability of both marbles being drawn, we must multiply both fractions.
Like this,
7/15 ⋅ 7/15 = 49/225.
49/225 in decimal form is 0.21777778
0.21777778 rounded to the nearest hundredth is 0.218.
Therefore, the probability of two blue marbles being drawn out of the bag is 0.218.
3. Sue's average for 9 games of bowling is 108. What is the lowest score she can receive for the
tenth game to have an average of 110?
Answers
Answer: 128
Step-by-step explanation:
Sue's average for 9 games of bowling is 108. Therefore, the total scores for the 9 games is:
= 108 × 9
= 972
To have an average of 110 in 10 games, her total score will be:
= 110 × 10
= 1100
Therefore, the lowest score that she can get will be the difference between the values calculated above and this will be:
= 1100 - 972
= 128

Los ingresos de Mary en 2019 fueron un 20 por ciento mayores que sus ingresos en 2018. ¿Cuál es la relación entre los ingresos de Mary en 2019 con respecto a sus ingresos en 2018?
a) 1 a 5
b) 5 a 6
c) 6 a 5
d) 5 a 1
e) 20 a 1
Answers
Answer:
La respuesta correcta es la opción d) 5 a 1.
Step-by-step explanation:
Para calcular la relación entre los ingresos de Mary en 2019 ([tex]I_{2019}[/tex]) con respecto a sus ingresos en 2018 ([tex]I_{2018}[/tex]), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:
[tex]I_{2019} = 20\% \: I_{2018}[/tex]
[tex] I_{2019} = \frac{20}{100}I_{2018} [/tex]
[tex] \frac{100}{20}I_{2019} = I_{2018} [/tex]
[tex] 5I_{2019} = I_{2018} [/tex]
Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

When the winning score in golf is the lowest number, the lowest number is -1.
The value of the expression -273 - (-576) will be:
= -273 - (-576)
= -273 + 576
= 303
Also, -56/4 = -14. The value of the expression (2 - 19) + (-12) will be:
= (2 - 19) + (-12)
= -17 - 12
= -29
The value of -2x = 22 will be:
-2x = 22
Divide both side by -2
-2x/-2 = 22/-2
x = -11
The value of 5 + 3x = -22 will be;
5 + 3x = -22
5x = - 22 - 5
3x = -27
x = -27/3 = -9
5(x + 3) = 35
5x + 15 = 35
5x = 35 - 15
5x = 20.
5x/5 = 20/5
x = 4

You decide to buy a car with a base price of $11,499 at an interest rate of 6.2%. The car will be compounded monthly in those 5 years. What will your monthly payment be? Round the money to the nearest hundredth
Answers
Answer:
A = $15,696.72
Step-by-step explanation:
Use the compound amount formula: A = P(1 + r/n)^(nt). Here the number of compounding periods is nt, or (12 per year)(5 years) = 60.
Our formula becomes A = $11,499(1 + 0.062/12)^60, which works out to:
A = $11,499(1 + 0.0052)^60, or
A = $15,696.72
The monthly payment is $15,696.72/60, or $261.61.
