Step-by-step explanation:
as shown on the lines, it takes the bird one second to fly 13 meters. the answer to the first blank is 1
using this ratio, 13 meters per second, we can find how long it takes for the bird to fly 39 meters.
13/1=39/x
this is 13x=39
x=3 seconds
use the same ratio to find distance
13/1=x/10
13=x/10

are Bananas are curved because they grow towards the sun ☀️
2
true or false
Answers
Answer:
true
Step-by-step explanation:
As bananas grow, the fruits start to become heavy and begin sinking towards the ground. However, fruits naturally seek the sun which means that as they mature, they start to curve upward in search of the sun’s rays. This is because bananas contain a chemical called auxin, a plant hormone that affects how the plant responds to sunlight.

If there are 1.61 kilometers in a mile and also 5,280 feet in a mile, then how many feet are there in 3 kilometers?
Answers
Answer:
There are 9838.5 feet in 3 kilometers.
Step-by-step explanation:
Given that:
There are 1.61 kilometer in a mile.
1 mile = 1.61 km
Also,
1 mile = 5280 feet
Comparing,
1.61 km = 5280 feet
1 km = [tex]\frac{5280}{1.61}[/tex] feet
1 km = 3279.50
3 km = 3279.50 * 3
3 kilometers = 9838.5 feet
Hence,
There are 9838.5 feet in 3 kilometers.
A distance of 3 kilometers is equal to 9,838.5 feet.
Given to us:
1 miles = 1.61 kilometers,
1 miles = 5,280 feet,
from the above to equations we can conclude,
[tex]1\ miles = 1.61\ kilometers = 5,280\ feet\\ 1.6\;kilometers = 5,280\ feet\\\\1\ kilometers =\dfrac{ 5,280\ feet}{1.61} \\\\1\ kilometers = 3,279.5\ feet[/tex]
So, now for 3 kilometers we can conclude that,
[tex]1\ kilometers = 3,279.5\ feet\\3\ kilometers = (3,279.5\times3)\ feet\\3\ kilometers = 9,838.5\ feet[/tex]
Hence, A distance of 3 kilometers is equal to 9,838.5 feet.

basically you just take the number beside x or y and divide it by the number that is behind the equal sign.
Answer:
x-intercept= -6 & y-intercept = 8
Step-by-step explanation:
To find the intercepts you just have to put the opposite value as 0 in the equation.
X-intercept:
-4x + 3(0) = 24
Y-intercept:
-4(0) + 3y = 24
Everything times 0 is 0, so it cancels out.
Then it is just simple dividing.
Future reminder:
Just remember this (x,y)
-X-intercept point (?,0)
-Y-intercept point (0,?)

find the probability that a number chosen at random from the integers between 5 and 16 inclusive is a multiple of 3 or a mutiple of 2
Answers
Answer: Numbers between 5 and 16 are:-
6, 7, 8, 9, 10, 11, 12, 13, 14 , 15 and 16.
Therefore, total number of outcomes =11
Numbers inclusive between 5 and 16 which are divisible by 2 or 3 are-
6 , 8, 9 ,10 ,12, 14 and 15.
Number of favourable outcomes = 7
Therefore, probability of getting a number which is either a multiple of 2 or 3 is:
p(e) = \frac{7}{11}p(e)=

The area of a rectangle is 1,872 ft2. The ratio of the length to the width is 9:13. Find the perimeter of the rectangle. A. 88 ft B. 117 ft C. 168 ft D. 176 ft
Answers
Answer:
Length = 36
Width = 52
Step-by-step explanation:
Area of rectangle = Length * width
Length = L ; Width = W
Area (A) = 1872 ft²
Ratio L:W = 9:13
Hence,
1872 = lw - - - (1)
l/w = 9/13 - - - (2)
From (2)
13l = 9w
l = (9/13)w - - (3)
Put (3) into (1)
1872 = (9/13)w * w
1872 = 9/13 w²
24336 = 9w²
24336 / 9 = w²
2704 = w²
w = 52
If w = 52
1872 = 52 * l
l = 1872 / 52
l = 36
Length = 36
Width = 52
