Answer:
3) 1 5/6 mi
4) a. 4 cm, 6 ft
b. 6.4 cm, 9.6 ft
c. same as part a
Step-by-step explanation:
3) Each of the given distances appears twice in the sum of side measures that is the perimeter. Hence by walking the perimeter twice, Kyle walks each of the given distances 4 times. His total walk is ...
4×1/3 + 4×1/8 = 4/3 + 4/8
= 1 1/3 + 1/2 = 1 2/6 + 3/6
= 1 5/6 . . . . . miles
___
4) Since the figure is rectilinear (all angles are right angles, and all sides are straight lines), the sum of partial dimensions in one direction is equal to the whole dimension in that direction.
a. 8 cm = 4 cm + x
8 cm - 4 cm = x = 4 cm
The distance in the room is ...
(4 cm)×(1.5 ft/cm) = 6 ft
b. 10.3 cm = 3.9 cm + y
10.3 cm - 3.9 cm = y = 6.4 cm
The distance in the room is ...
(6.4 cm)×(1.5 ft/cm) = 9.6 ft
c. The answer to part b was obtained in the same way as the answer to part a. The unknown dimension is the difference of given dimensions. The actual length in the room is the model length multiplied by the inverse of the scale factor.
Answer:
Number 4
Step-by-step explanation:
I have done this quiz before, and that is what it looks like
I don't know if I am right, but good luck!
r > 0 = r is greater than 0
r ≤ 8 = r is less than and equal to 8
0 ≤ r ≤ 8
The estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000
<h3>Estimate the amount of money Yousef will borrow by first rounding to the hundred</h3>
The amount borrowed are given as:
Last term = 1690
This term = 2345
When the amounts are rounded to the nearest hundred, the amounts borrowed become:
Last term = 1700
This term = 2300
The total amount is then calculated as:
Total amount = Last term + This term
Substitute the known values in the above equation
Total amount = 1700 + 2300
Evaluate the sum
Total amount = 4000
Hence, the estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000
