The length of a garden is 23m, correct to the nearest metre.
Write down the least possible length of the garden.
Answer:
22.5m
Step-by-step explanation:
Since it's correct to the nearest metre, it has an interval of ± 0.5
Using rounding concepts, it is found that the least possible length of the garden is of 22.5m.
------------------
If the first decimal digit is between 0 and 4, rounding to the nearest integer, the integer part remains the same.If the first decimal digit is between 5 and 9, rounding to the nearest integer, one is added to the integer part.Thus, in the context of this problem, garden lengths between 22.5 and 23.4 are rounded to 23m, and thus, the least possible length of the garden is 22.5m.A similar problem is given at https://brainly.com/question/13241511

Two airplanes leave the airport at the same time. One plane is flying 700mph at a bearing of N46°W and the other plane is flying 895mph at a bearing of
N43° E. After 3 hours, how far are the planes from one another?
9514 1404 393
Answer:
3380 miles
Step-by-step explanation:
The distance separating the planes can be found using the law of cosines. One plane has gone 3×700 = 2100 miles; the other has gone 3×895 = 2685 miles. The angle between their flight paths is 46°+43° = 89°. Then the separation (s) is ...
s² = 2100² +2685² -2(2100)(2685)cos(89°) = 11,619,225 -11,277,000×0.01745
s² ≈ 11,422,414.21
s ≈ √11,422,414.21 ≈ 3379.7
The planes are separated by about 3380 miles after 3 hours.

Answer:
for #1 it's 1, 4, 5, 6
for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different

2. The following triangle, ∆, has angle measures as shown.
Step 1: What is the measure of angle C? Show your work.
Step 2: What is the value of x? Show your work.
Answer:
x=29. Angle C= 93
Step-by-step explanation:
3(x+2)= 3x+6.
3x+6+52+35= 3x+93.
180-93=87.
87/3= 29. So that means x=29.
for proof you can do 3(29)+93 and you'll get 180.
For angle C; 3(29+2)= 3x31. 31x3= 93.
Angle C= 93 degrees.

"The sum of a number and nineteen has the same value as one less than the product of that number and five"
Answer:
x = 5
Step-by-step explanation:
Set up an equation:
x + 19 = 5x - 1
Add 1 to both sides:
x + 20 = 5x
Subtract x from both sides:
20 = 4x
Divide both sides by 4:
x = 5
