From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.
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 chord is 10cm from the centre of a circle of radius 15cm. Find the length of the chord.
Answer: 21.44 cm
Step-by-step explanation:
Given
Radius r=15 cm
distance of chord from the center is 10 cm
From the figure, the length of the chord is AC
Applying Pythagoras
[tex]\Rightarrow AO^2=OB^2+AB^2\\\Rightarrow AB^2=15^2-10^2\\\Rightarrow AB^2=225-100=115\\\Rightarrow AB=\sqrt{115}=10.72\ cm[/tex]
The length of the chord is [tex]AC=2AB=21.44\ cm[/tex]
What are the coordinates of Rx=3(G)?
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

It can be deduced that the addition of -3 and 4 will be 1.
How to add the numbersIt can be deduced that the addition of -3 and 4 will be;
= -3 + 4
= 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

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
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.

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?
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

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
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.

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.
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
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?
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.
