Answer:408=screen time
Step-by-step explanation:240+168 70%=168
make sure to like with the heart
Answer:
I believe 408 minutes a day
Step-by-step explanation:
So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.
ex.
240/10 = 24
24x7=168
240+168= 408
to do with 100s like 73% then divide the whole by 100 :)

Answer:
Area = 113.01 m²
Step-by-step explanation:
From the picture attached,
Area of the quadrilateral ABCD = Area of triangle ABC+ Area of triangle ACD
Construction to be done → Draw a perpendicular from a point A to the opposite side CD
Area of Δ ABC = [tex]\frac{1}{2}(AB)(BC)[/tex]
= [tex]\frac{1}{2}(12)(10)[/tex]
= 60 m²
Area of triangle ACD = [tex]\frac{1}{2}(AE)(CD)[/tex]
From ΔAEC,
sin(29°) = [tex]\frac{AE}{AC}[/tex]
AC = [tex]\sqrt{(12)^2+(10)^2}[/tex] [By Pythagoras theorem]
AC = [tex]\sqrt{244}[/tex]
AC = 15.62 m
Therefore, AE = 15.62sin(29)
= 7.57 m
Area of ΔACD = [tex]\frac{1}{2}(7.57)(14)[/tex]
= 53.01 m²
Area of ABCD = 60 + 53.01
= 113.01 m²
The graph shows a volume of ice cubes versus temperature in degrees celsius. Which of the statements is false?
A. The correlation coefficient is close to zero.
B. Temperature is strongly correlated to the volume of ice cubes.
C. Temperature is the explanatory variable.
D. The data show a negative linear relationship.
The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.
What is the correlation coefficient?Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
Types of correlation-
Positive correlation coefficient- When the value of correlation coefficient is positive, then the value of one variable increases with increase in other variable.Negative correlation coefficient- When the value of correlation coefficient is negative, then the value of one variable decreases with increase in other variable.
The graph shows a volume of ice cubes versus temperature in degrees Celsius.
For a perfect correlation, -1 or +1 values is ideal. Here, some relation can be seen in a negative straight line, which suggest that the correlation coefficient is not close to zero.
Both volume and temperature has strong correlation for linear line where, temperature is the explanatory variable.
Thus, the statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)
Answer:
y = 2/5x + 18.
Step-by-step explanation:
The line will have the same slope of 2/5.
Using the point-slope form of a line:
y - 12 = 2/5(x - -15)
y - 12 = 2/5(x + 15)
y = 2/5x + 6 + 12
y = 2/5x + 18.
Answer:
y = (2/5)*x + 18
Step-by-step explanation:
Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .
Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y = (2/5)*x + 18.
What is the value of x in the equation 3/4 x + 24 = x − 12 ?
Answer:
x = 144
Step-by-step explanation:
3/4x + 24 = x - 12
3/4x - x = -12 - 24
3/4x - 4/4x = -36
-1/4x = -36
x = -36/-1/4
x = 144

Carlita is flying a kite at the beach. She wants to know the altitude of the kite when she uses 25 yards of string at an angle of elevation of 56°. Find the altitude of Carlita's kite to the nearest hundredth.
13.98 yards
20.73 yards
30.16 yards
37.06 yards
Please Answer as soon as you can I am giving 50 points!
Answer:
Step-by-step explanation:
13.98
The altitude of Carlita's kite to the nearest hundredth should be considered as the 13.98 yards when she uses 25 yards of string at an angle of elevation of 56.
Calculation of the altitude of Carlita's kite:Since she uses 25 yards of string at an angle of elevation of 56°
So we know that
cos 56 degrees = 0.5592
Now the altitude is
= (25) (0.5592)
= 13.98 yards
We basically multiplied these two so that the altitude should come.
hence, the first option is correct.

Jay makes a base salary of $2000 per month. Once he reaches $50000 in total sales, he earns an additional 5% commission (salary) on the amount of sales over $50000. Let s be the amount of his total sales for the month and j(s) be the amount of his salary for the month.
Answer:
[tex]j(s) = 0.05s -500[/tex]
Step-by-step explanation:
Given
[tex]Base\ Salary = 2000[/tex]
[tex]Commission = 5\%[/tex] on Sales over 50000
Required
Determine the function j(s) for sales over 50000
Represent the total sales in a month with s.
Sales over 50000 in that month will be: s - 50000
So, the function j(s) is:
j(s) = Base Amount + Commission * Sales over 50000
[tex]j(s) = 2000 + 5\% * (s - 50000)[/tex]
Convert % to decimal
[tex]j(s) = 2000 + 0.05 * (s - 50000)[/tex]
Open bracket
[tex]j(s) = 2000 + 0.05 * s - 0.05 * 50000[/tex]
[tex]j(s) = 2000 + 0.05s - 2500[/tex]
Collect Like Terms
[tex]j(s) = 0.05s - 2500 + 2000[/tex]
[tex]j(s) = 0.05s -500[/tex]

Answer:

Step-by-step explanation:
the sum of the angles in a triangle add up to equal 180
180-73-13=94
Answer: X = 89°
Step-by-step explanation:
At first glance I could tell this was an isosceles triangle, the angles of an isosceles triangle add up to 180°. So just add 73° + 13° = 91° so then you subtract 91° from 180° and you get 89°.
