Hector’s plant is about 46 cm tall.
Explanation:
Since there are 2.54 cm in an inch, you do
18 * 2.54
18 * 2.54 = 45.72
45.72 ≈ 46
So for question 7 part A the picture will be a triangle similar to the the one that shows the umbrella's height. But the base will be 40 and the height will be 130.
for part B the angle of depression can be found using the trigonometric function of tangent.
tan x = 40/130
tan^-1 (tan x) = tan^-1 (40/30)
x = 17 degrees
I hope i am right
Answer:
(4+5)3-8 = 19
Step-by-step explanation:
1) You know that the parenthesis are going to go around 3-8 or 4+5 because that is the only way multiplication is involved. If you put them anywhere else it doesn't change the answer.
2) Try solving the problems (use PEMDAS)
(4+5)3-8 = 9*3-8 = 27-8 = 19
4+5(3-8) = 4+5(-5) = 4-25 = -21
The triangle is an isosceles triangle because of its degrees. A triangle consists of 180 degrees therefore, 180-90-45 simply makes it 45 matching the other side.
So we can assume that side b is also equivalent to side a. Here we use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25+25=50
The square root of 50 is 7.1
x= 7.1
Answer:
1) Rizza's average speed is 27 km/h.
2) The distance between Barretto and Pampanga is 294 km.
3) Aaron's journey was 3.5 hours long.
Step-by-step explanation:
1) Time taken to cove the distance = 20 minutes
60 minutes = 1 hour
So that, 20 minutes = 
hours
= 
hours
Distance covered = 9 km
But,
speed = 
Rizza's average speed = 9 ÷
= 9 x 3
= 27 km/h
Rizza's average speed is 27 km/h.
2) Time taken = 3.5 h
the car's average speed = 84 km/h
Distance between Barretto and Pampanga = average speed x time taken
= 84 km/h x 3.5 h
= 294 km
The distance between Baretto and Pampanga is 294 km.
3) The uniform speed implies that Aaron did not accelerate during his journey.
Distance covered = 210 km
uniform speed = 60 km/h
time taken = 
= 
= 3.5 hours
Aaron's journey was 3.5 hours long.
