Answer:
258.75km
Step-by-step explanation:
345/4=86.25
Can travel 86.25km an hour
86.25*3=258.75
Therefore it can travel 258.75 in 3 hours
Answer:
yes
Step-by-step explanation:
The formula to finding the hypotenuse of a right triangle is a^2+b^2=c^2. So since the longest side is the hypotenuse, the 82 in. is the hypotenuse. 18^2+80^2= 6724, then we square root it, square root of 6725 is 82.

Step-by-step explanation:
The expression needed is the highest temperature of the week subtracted by the lowest temperature of the week. That is to say:
Answer:
x = 9
Step-by-step explanation:
This problem involves knowing the sum of angles in a triangle as well as the sum of supplementary angles. In any triangle, the sum of all the angles will always add up to 180°. Supplementary angles add up to 180° and form a straight line. In order to solve for 'x', we must set up an equation where the sum of the angles is equal to 180°. Since the last angle of the triangle is not given, but we know that the value will be equal to 180 - (14x + 1), we can simplify this to 180 - 14x -1 or 179 - 14x. We also know that this angle plus the other two angles of the triangle will add up to 180:
89 + 179 - 14x + 5x - 7 = 180
Combine like terms: 261 - 9x = 180
Inverse operations: 261 - 261 - 9x = 180 - 261 or -9x = -81
Solve for x: x = 9
The value of the expression will be 8.166.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The mathematical expression is,
⇒ 13.41 x (5.4 divided by 9)
Now,
Solve the expression as;
⇒ 13.41 x (5.4 divided by 9)
⇒ 13.41 x (5.4 ÷ 9)
⇒ 13.41 x 0.6
⇒ 8.166
Thus, The value of the expression will be 8.166.
