Answer:
D- 7.3
Step-by-step explanation:
For this problem, we are given a parallelogram with a diagonal drawn, inside it there are markings for a few angles. We need to determine the unknown angles.
Opposite sides of a parallelogram are parallel, this means we can treat the diagonal as a transversal line that crosses two parallel lines. Since this is the case, the angles 33º and xº are alternate interior angles and have the same length:
The opposite angles in a parallelogram are congruent, therefore:
The sum of internal angles is 360º, therefore we have:
The value of x is 33º, the value of y is 38º and the value of z is 109º.
Answer:
1) -95.
2) 15.
3) The conference center is on floor 5.
Step-by-step explanation:
1) Evaluating gives
2) Substituting gives
3) After going 4 floors down, we are on level -4. After going 9 floors up to the desired room, we are on level -4+9=5. So the conference center is on floor 5.
Find the volume of each tank by multiplying the length by the width by the height:
Terry: 14 x 12 x 10 = 1680 cubic cm.
Bob: 13 x 15 x 8 = 1560 cubic cm
Terry’s aquarium is larger and can hold more water.
V = -5 because you subtract 4 from both sides then divide both sides by -7 and you get -5
