calculate the 25% of 6 hours 20 minutes
Answers
6 hours and 20 mintues = 380 mintues
25% of 380 = 95 mintues = 1 hour and 35 mintues
Step-by-step explanation:
your welcome also use the website calculator.net it had a percentage calculator
Answer:
The answer is 95 minutes.
Step-by-step explanation:
1. Convert 6 hours to minutes which would lead to 360 minutes.
2. 360 minutes + 20 minutes = 380 minutes.
3. Now find 25% of 380 minutes.
How I found 25%.
1. 50% of 380 = 190.
2. 50% of 190 = 95.
Now since the half of our base half is 95 then 2 halfes are 2 25% but we need 1 only so we can conclude that, 25% of 380 minutes is 95.
Hope this helped :).

B) X- intercept at (5,0)
C) vertical asymptote of x=-4
D) horizontal asymptote of Y=4
Answers
Answer:
B
Step-by-step explanation:
Plato
The x- intercept of g(x) is at (5,0), the correct option is B.
What is a Function?A function is a law that relates a dependent and an independent variable.
The function is g(x) = -f(x-4)
The x intercept is when y =0
The function in the graph f is 0 at x =1
g(x) = -f( 5-4) = -f(1) = 0

A triangle has sides 12cm, 9cm and 15cm. Is the triangle right-angled? Justify your answer
Answers
Answer:
yes
Step-by-step explanation:
Yes this triangle is right angled and can be justified using the Pythagorean theorem. The theorem states that: [tex]a^{2} +b^{2} = c^{2}[/tex]. Substitute using the given values:
(9^2)+(12^2)=15^2
81 + 144 = 255
255 = 255.
It satisfies the theorem therefore it is a right angle triangle.

Find the measure of the exterior angle.
Answers
Answer:
Option (C)
Step-by-step explanation:
By the property of an exterior angle,
Exterior angle of a triangle is equal to the sum of two opposite interior angles.
(15x + 34)° = 29° + (12x + 26)°
15x + 34 = 29 + 12x + 26
15x - 12x = 55 - 34
3x = 21
x = 7
Measure of exterior angle = (15x + 34)°
= 15(7) + 34
= 105 + 34
= 139°
Option (C) is the answer.

= 30-2/8-1
= 28/7
= 4
Equation:
y - 2/x - 1 = 4
y - 2 = 4(x-1)
y - 2 = 4x - 4
y = 4x - 4 + 2
y = 4x - 2
Answer:
y = 4x - 2
Step-by-step explanation:
→ First find the gradient
[tex]\frac{x2-x1}{y2-y1} =\frac{30-2}{8-1} = 4[/tex]
→ Put into y = mx + c format
y = 4x + c
→ Substitute ( 1 , 2 ) into y = 4x + c
2 = 4 + c so c = -2
→ Rewrite into equation format
y = 4x - 2
Myopia in children. Myopia, also called short-sightedness, is a common visual impairment that is reaching alarming proportions worldwide. The condition typically develops in school-age children and adolescents. It has long been thought that the condition was associated with too much reading, but recent evidence suggests instead that a lack of exposure to natural outdoor light may play a role. To investigate this new theory, researchers compared rates of myopia among randomly selected young children (6 and 7 years old) of Chinese ethnicity living in either Sydney (Australia) or Singapore. The researchers found that 4 of the 124 children in the Australian sample had myopia, compared with 183 among the 628 children from Singapore.
a. Display the findings in a two-way table. What percent of the children in the study had myopia? What is that percent among the children living in Australia and among those living in Singapore?
b. The researchers obtained information for most of the children in the study about their weekly amount of time in hours) spent reading or writing and the weekly amount of time in hours) spent on outdoor activities. Here are the summary statistics:
Time reading/writing Number of children Mean Standard deviation
Australia 109 20.8 13.9
Singapore 611 17.8 8.8
Time outdoors Number of children Mean Standard deviation
Australia 102 13.75 1.02
Singapore 586 3.05 0.12
How do the children from both countries in this study differ in how they spend their time?
c. Does the study suggest that more time spent reading or writing is associated with a greater risk of myopia among the enrolled children? Does it suggest that more time spent outdoors is associated with a greater risk of myopia? Can we draw a conclusion of causality based on this study?
d. The children enrolled in this study were all of Chinese ethnicity. What is the advantage in this study of collecting data from children with the same ethnicity compared with selecting random samples of children from each location regardless of ethnicity?
Answers
Answer:
a. A two way table is presented as follows;
[tex]\begin{array}{cccc}&Had \ Myopia&Do \ not \ have \ Myopia& Totals\\Sydney \ (Australia)&4&120&128\\Singapore&183&445&628\end{array}[/tex]
ii) The percentage of students in the study that have myopia are approximately 24.867%
iii) The percentage of children living in Australia with myopia are approximately 3.2258%
The percentage of children living in Singapore with myopia are approximately 29.14%
b. Children in Australia spend more time reading, writing and also outdoors than children in Singapore
c. The study does not suggest that more time spent reading or writing is associated with a greater risk of myopia among the enrolled children
The study does not suggests that more time spent outdoors is associated with a greater risk of myopia
d. The advantage is to reduce associated variables the generate more accurate findings or result
Step-by-step explanation:
a. A two way table is presented as follows;
[tex]\begin{array}{cccc}&Had \ Myopia&Do \ not \ have \ Myopia& Totals\\Sydney \ (Australia)&4&120&128\\Singapore&183&445&628\end{array}[/tex]
ii) The percentage of students in the study that have myopia are;
(4 + 183)/(124 + 628) × 100 ≈ 24.867%
iii) The percentage of children living in Australia with myopia is given as follows;
4/124 × 100 ≈ 3.2258%
The percentage of children living in Singapore with myopia is given as follows;
183/628 × 100 ≈ 29.14%
b. The data for the time spent reading and writing is presented as follows;
Number of children [tex]{}[/tex] Mean Standard deviation
Australia 109 [tex]{}[/tex] 20.8 13.9
Singapore [tex]{}[/tex] 611 17.8 8.8
The data for the time spent outdoors is presented as follows;
Number of children [tex]{}[/tex] Mean Standard deviation
Australia 102 [tex]{}[/tex] 13.75 1.02
Singapore [tex]{}[/tex] 586 3.05 0.12
From the data, more children in Australia spend more time reading and writing and also outdoors than children in Singapore
c. From the data, more children spend their time reading and writing in Australia and are also less likely to develop myopia than children in Singapore
Therefore, the study does not suggest that more time spent reading or writing is associated with a greater risk of myopia among the enrolled children
Similarly, the study does not suggests that more time spent outdoors is associated with a greater risk of myopia
d. The advantage of collecting data from children with the same ethnicity compared with selecting random samples of children from each location regardless of ethnicity is to reduce the variables or influential factors that may alter the impact on the test and the results

Draw a line from point A to point C.
ΔACD is a right triangle.
Solve for ∠CAD:
sin CAD = 3/5 = 0.6000
∠CAD = 36.87°
arc CD = 2 x 36.87° = 73.74°
arc BC = arc CD = 73.74°
arc DB = 147.48°
∠BAD = 1/2 (147.48°) = 73.74°
draw a line from point D to point B
ΔBAD is a right triangle.
cos 73.74° = AB/5
AB = 1.4
