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 :).

Answer:

180 square inches

Step-by-step explanation:

First off since the square will be easiest to do

a=a^2

a=6^2

a=36

now for the triangles

a= height of triangle * base/ 2

a= 12*6/2

a= 36

and since there is 4 of the triangles we multiply 36 by 4

=144

now we add 144 to 36 and we have the total

Answer:

B

Step-by-step explanation:

Plato

The x- intercept of g(x) is at (5,0), the correct option is B.

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

The 100th term of the sequence is 195.

It is a sequence where the difference between each consecutive term is the same.

Example:

2, 4, 6, 8, 10 is an arithmetic sequence.

We have,

a(n) = 2n - 5

For n = 100,

a(100):

= 2 x 100 - 5

= 200 - 5

= 195

Thus,

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

lateral area of cylinder =2×pi ×radius×height

lateral area of cylinder =2×3.14×1×2

lateral area of cylinder=12.56 unit²

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.

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

AB = 1.4 or 7/5

Step-by-step explanation:

(Excuse my rambling but I wanted to be sure of myself)

AD = 2(5/2) = 5

AD is a diameter.

any triangle in a circle with the hypotenuse as the diameter is a right triangle.

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

Answer: x4

Step-by-step explanation:

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.
