Answer:8000
Step-by-step explanation:
Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Multiple choice questions = 5
True questions = 15
Given that:
Total number of questions = 20
Total worth of point = 100
Multiple choice questions (M) = 11 points each
True false questions (T) = 3 points each
Hence,
M + T= 20 ____(1)
11M + 3T = 100 ____(2)
M = 20 – T
Using the relation in (2)
11(20 – T) + 3T= 100
220 – 11T + 3T= 100
220 – 8T = 100
-8Tf = 100 – 220
-8T = – 120
T = 120/8
T = 15
Mc = 20 – 15
Mc = 5
Multiple choice questions = 5
True false questions = 15
Answer:
D) (5x + 6)(5x + 6)
Step-by-step explanation:
area of square = 6 x 6 = 36
area of rectangle = 5x(5x + 12) = 25x² + 60x
total together = 25x² + 60x + 36
factored:
(5x + 6)(5x + 6)
Answer:
x = 65°
y = 71°
z = 44°
Step-by-step explanation:
- Reason: the angle x is opposite to the 65° angle, this means that these two angles are congruent, thus they have the same value.
- Reason: the angle y is congruent to the angle of 71 ° this because if we lengthened the lines (similar to that shown with the angles x and 65 °) we will notice that the angle opposite to y is 71 ° and therefore y is also equal to 71 °
- Workout the size of angle z:
The sum of the interior angles in a triangle is always equal to 180 °, in this case the interior angles are x, y and z. Since we already know the values of x and y, we can find z by adding the values and equaling 180°:
65° + 71° + z = °180
and we solve for z:
136° + z = 180°
z = 180° - 136°
z = 44°
