Answer:
Step-by-step explanation:
Given as :
The distance cover while running =
= 5 miles
Let The speed for running = 
The distance cover with bike =
= 80 miles
The speed for biking =
= 15 mph + 
Total Time taken = 5 hours
Now Time = 
∴ 5 hour =
+ 
Or, 5 hour =
+ 
Or, 5 hour = 
or, 5 × (
) = 
Or,
-
= 0
or,
= 0
or,
= 0
Or,
= 0
Or,
= 0
Or,
= 0
∴
= 3 , - 5
So, the running speed = 3 mile per hour
And the biking speed = 15 mph + 3 mph = 18 mile per hour
Hence The running speed of Stu is 3 mile per hour . Answer
Answer:
110 ft
Step-by-step explanation:
The length of fencing is four times the perimeter of one garden.
The formula for the perimeter of a rectangle is
P = 2l + 2w
The total perimeter for all four rectangles is
P = 4× (2l + 2w) = 8l + 8w
Data:
l = 9¼ ft
w = 4½ ft
Calculation:
P = 8l + 8w = 8×9¼ + 8×4½ = 72⁸/₄ + 32⁸/₂ =(72 + 2) + (32 + 4) = 74 + 36 = 110 ft
The total length of fencing is 110 ft.
Answer:

Step-by-step explanation:
Given 2 similar figures with ratio of sides = a : b, then
ratio of areas = a² : b²
Here ratio of sides = 52 : 68 = 13 : 17 ← in simplest form, thus
ratio of areas = 13² : 17² = 169 : 289 = 
Answer:
least to greatest in order: -5/2(-2.5), -2.5, -2, -1.75, -1, 1.75, 9/4(2.25)
F(3)=16 i saw this problem before so it should be the answer in the end
