Answer:
by dividing 325 by 48.
The answer comes out to 6.77
But since the number of buses must be a whole number, we will need 7 buses to carry the 325 students and teachers on a field trip.
so the answer is 7 buses
Answer:
Step-by-step explanation:
9/50 // 12 / 1 You have a 4 tier fraction here. You must invert the denominator (12/1) and multiply
9/50 * 1/12 Cancel 3 in the 9 and 3 in the 12
3/50 * 1 / 4 Multiply the numerators together and the denominators together.
3 / 200 each bottle with have 3/200 L or 1.5 / 100 L syrup in it.
1.5 / 100 L = 1.5 * 10 / 100 * 10 = 15 mL of medication in each bottle.
To complete this problem, we are going to need to use the Pythagorean theorem.
1.find x. as mentioned earlier, we are going to use the Pythagorean theorum (a²+b²=c²). substitute a b and c for the values on the triangle then solve:
x²+3²=5² substitute
x²+9=25
x²=25-9 subtract
x²=14
x≈3.7 solve to the nearest tenth
2. x is about 3.7km. now we need to find y. to do so, we are going to do the same steps that we did to find x:
y²+3²=7²
y²+9=49
y²=49-9
y²=40
y≈6.3
3. now we know all 3 horizontal side lengths so all we need to do to find the total horizontal distance is add the 3 together:
3.7+3+6.3
13
4. after doing all that math we finally got the answer: The plane's total horizontal distance is about 13km.
I hope this was helpful! :)
Answer:
x = 20
y = 70
Step-by-step explanation:
Solve for x:
5x - 20 = 3x + 20
2x - 20 = 20
2x = 40
x = 20°
Solve for y:
x + y = 90°;
(20) + y = 90°
y = 90 - 20
y = 70°
Hope this helps!
The point of interest is where the graphs cross.
(x, y) = (11, 5)
_____
Linear equations can be solved by any of a variety of methods. Using substitution for y, you have
.. 7x +3(27 -2x) = 92
.. x = 11 . . . . . . . . . . . . . collect terms, subtract 81
Then
.. y = 27 -2*11 = 5
