1) you do 144× 12 since you want to know how much all kids pay so its 1728 dollars.
2) they want 2 section a, 3 section b, and 2 section c, and sincc you want to know total you multiply number of tickets bought by cost per ticket, so its 2(10)+3(20)+2(30)=180 total cost.
3) sine they have 350 dollars yoy subtract cost of the ps4 from the amount they have and you get, 350-234=116 dollars remaining.
4) since they make 15 per lawn you write 15x, x representing number of lawns cut, and you set that equal to 225, so its 15x=225 then you divide 15 on both sides to get x= 15 lawns they need to cut.
5) you just divide 2/4 since they ate two of four slices and you get .5 then convert that to a decimal by moving decimal point 2 spaces over to get 50%.
6) Just add up all the costs of each song, so you get .99+1.19+1.5+.99 = 4.67 dollars as total cost.
7) since 60 min is in an hour and you have 30 min left over it would be 1hr and 30 min.
8) since its Monday through Friday which is only 5 days you multiply that by 4 weeks to get 20 days then you multiply by 30 since they study 30 min on each of those days, so you get 20×30 which is 600min of studying, but since it want is in hours divide 600 by 60 to get 10hrs of study.

The square root function f(x) is x <= 7
Options are :
A. 7 is subtracted from the x-term inside the radical.
B. The radical is multiplied by a negative number.
C. 7 is added to the radical term.
D. The x-term inside the radical has a negative coefficient.
Option D is correct, which is : The x-term inside the radical has a negative coefficient.
Given, the domain of the square root function f(x) is x <= 7
Consider the function y = √x.
The domain of this function is x ≥ 0 and the range is y ≥ 0.
The expression inside the radical must be greater than or equal to zero.
Now, if x ≤ 7
x - 7 ≤ 0
7 - x ≥ 0
And the function y = √(7-x) will have the domain x ≤ 7.
This implies that the x-term inside the radical has a negative coefficient.
Therefore, the statement that the x-term inside the radical has a negative coefficient must be true.

Answer:
x = 18 ; y = 10 ; z = 102°
Step-by-step explanation:
The triangle in the pic is an isosceles triangle.
As it is an isosceles triangle , it's two sides will be equal .
Also, both the base angles will be equal.
According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,
They way I would do it other than with a calculator would be
27 x (90 - 0.5) which is the same as 27 x 89.5
=> 27 x 90 - 27 x 0.5
27 x 90 is (3 x 9) x 90 or 3 x 9 x 90
9 x 90 = 810
3 x 810 = 2430
Then subtract 27 x 0.5, or 27 / 2
2430 - 27 / 2
=> 2430 - 13.5
= 2416.5
Final answer:
2416.5
