Start by turning the mixed number to an improper fraction by multiplying the 3 and 4 to get 12 and then add on 3 to that to get 15/4.
So not you have -2/3 ÷ 15/4. Do the reciprocal of 15/4 to get 4/15 and change the ÷ to a x (that's multiplication sign. After that multiply. -2/3 x 4/15 and the answer would be -8/45 :)
Answer:
The answer would be D. 38.7 miles per hour. To figure this out you must replace the d with 41 and the t with 2.3 so you get an equation that looks like this, 41=r-2.3. With this you can easily subtract 41-2.3 and you get 38.7 as the r. ;)

Answer:The side opposite to the obtuse angle in a obtuse triangle is the largest side of that triangle.
Step-by-step explanation:
- The obtuse angle is an angle that is more than 90° and less than 180°.
- Any triangle cannot have two angles equal to or more than 90° .
So if a triangle has an obtuse angle then it will be the only obtuse angle in the triangle, rest of the other two angles must be smaller than that.
Also, we know that the side opposite to the lager angle is larger.
Therefore, the side opposite to the obtuse angle in a obtuse triangle is the largest side of that triangle.
Answer:
You have to find the hypotenuses of the triangle to get the area of the entire area of the shape. Once you have the length of the hypotenuses then you can use that value to calculate the area of the triangle and the area of the box above.
Hyp = sqRoot ( 3.16^2 + 6.32^2) = sqroot(50) = 7.07
Area of Triangle = 1/2 x b x h = 1/2 x 6.32 x 3.16 = 9.99= 10
Are of square above triangle = l x w = 7.07 x 7.07 = 49.99 = 50
Total area = 10 + 40 +10 +50 = 110 SQ UNITS
