Answer:
Gradient is change in y over change in x.
gradient = y1-y2 ÷ x1-x2
=7-11 ÷ 3-5
=-4 ÷ -2
=2
Answer: 40
Step-by-step explanation: If she made 4 baskets in a half an hour then one hour she would make 8 in one hour and in 2 hours she would make 16 because 8 hours from the first hour and 8 more from the second hour. Because there is 1 hour and in the hour she made 8 if she needs 5 hours just multiply 8 by 5. That would give you 40.
Answer:
Height of second tower = 17.32m
Step-by-step explanation:
I have attached a diagram depicting the question.
From the diagram, The first tower is depicted by side AEB and the second tower CD.
While d is the distance that separates the two towers and it's given as 15m.
Now, since the angle of depression of the second tower’s base is 60°, then for triangle BAC. Angle C = 60°.
Thus; using trigonometric ratios;
tan 60° = AB/AC.
This gives; AB = d*tan 60°
Similarly, for the triangle BED, BE = d*tan 30°
Since, AE = CD, thus ;
CD = AB − BE
CD = d (tan 60° − tan 30°)
CD = 15(1.7321 − 0.5774)
CD = 15 × 1.1547
CD ≈ 17.32 m.
So, height of second tower = 17.32 m
Answer:
1a. -4 3/5
1b. -4 3/5
2. 33
Step-by-step explanation:
1a. -4 4/5 + 1/5 = -4 3/5
1b. -4 2/5 + (-1/5) = -4 3/5
2. (-16 -35) + 18 = -33
You would need to draw the number 33 to get a score of 0.
