Answer:
a-135 hot dogs and 245 sodas were sold.
Step-by-step explanation:
Our equations are:
1.25h + 0.75s = 352.50
h + s = 380
Let's use substitution to solve for this system. In the second equation, let's write h in terms of s:
h + s = 380
h = 380 - s
Now, let's plug in 380 - s for h in the first equation:
1.25h + 0.75s = 352.50
1.25(380 - s) + 0.75s = 352.50
We can now solve for s fairly easily:
1.25(380 - s) + 0.75s = 352.50
475 - 1.25s + 0.75s = 352.50
0.5s = 122.5
s = 245 sodas
We can already see which answer choice will match: A, and that is our answer.
Answer: The measure of fourteenth angle is 120°.
Step-by-step explanation:
Since we have given that
Total number of angles in 14 gon = 14
Sum of measures of 13 angles = 2040°
As we know that sum of all angles in 14 gon would be

So, the measure of fourteenth angle would be

Hence, the measure of fourteenth angle is 120°.
Answer:
p = 8/25
Step-by-step explanation:
500 - 340 = 160 girls
p = 160/500
p = 8/25
What thing do we need to do
Answer:
3,36 in^2
Step-by-step explanation:
The geometric shape shown in image is called a trapezoid
to calculate the area of a trapezoid we use the following formula:
1/2*(a+b)*h (a and b are bases, h: height)
bases are 1.3 and 3.5 and height is 1.4
1/2(1.3 + 3.5)*(1.4) = 3,36 the area is stated in square units so the answer is
3,36 in^2
