1t 1 ton is 2 thousand lbs
You basically want to write the total number of people using x and y for children and adults, and then write the cost function using the values you know for the ticket prices. next, you want to want to rearrange your total people equation so that you can write either x in terms of y or y in terms of x. finally, you can plug that into your cost equation and solve. (you then use the rearranged total people equation to solve for the other variable).
hope this helps :)
Answer:
The other angle is 60°
Their ratio is 1 : 2
Step-by-step explanation:
Let us revise some special angles
A pair of complementary angles is two angles their sum is 90°
A pair of supplementary angles is two angles their sum is 180°
In the question
∵ One angle of the pair of complementary angle = 30°
∵ The sum of the two complementary angles = 90°
→ Subtract 30° from 90° to find the other angle
∴ The other angle = 90° - 30° = 60°
∴ The other angle is 60°
To find the ratio of them put them in the form of the ratio, then simplify the ratio to its simplest form
∵ Their ratio = 30 : 60
→ Divide both sides by 10
∴ Their ratio = 3 : 6
→ Divide both sides by 3
∴ Their ratio = 1 : 2
∴ Their ratio is 1 : 2
Answer:
B. 102 cm
Step-by-step explanation:
The first step would be to find the area of the whole figure and subtract the white area off.
So, to do that simply multiply the length x width to get the area of the whole figure.
20 x 6 = 120(area of the whole figure)
Next, 20-11 = 9 is the length of the figure and because the square has a side length of 3, the other side would also have to be 3.
3 x 3 = 9(area of the smaller square.
9-3=6
6-3=3
Area of triangle = Base x Height Divided by 2.
So, 3x6=18/2=9
9+9=18
Finally, subtract 18(total area of white smaller shapes) from 120 and you will get the final answer
102 cm.
Answer:
303
Step-by-step explanation:
So the equation to find a term is An=a1+(n-1)d
An represents the value of the number (n)
and n is the selective that you want
d is the difference between the first and second term which is 23-18=5, and you can see that adding 5 to the previous term gives the following term.
a1 is the first term in the sequence
so knowing all that now you can go back and inset all variables into the equation
An=18+(58-1)5
An=303
Hope that helps :)
