In every case the larger number is rounded up to 2E13.
Divide this by 3E8:
2E13 = 200000E8
-------- --------------- is approx equal to 70000 (dollars).

![625 \times 8 - 1](https://tex.z-dn.net/?f=625%20%5Ctimes%208%20-%201)
lets times 625 to 8 then if we got the answer then minos to 1 .
the answer of that is 4,999
Answer: her speed on the bicycle is 8 mph
Step-by-step explanation:
Let x represent the speed at which she walks. If she rides 6 mph faster than she can walk, then the speed at which she rides is (x + 6) mph
Distance = speed × time
Eli walk from her house to a friends house in one hour. This means that the distance covered is 1 × x = x miles.
Distance on her bicycle in 15 minutes. Converting 15 minutes to hours, it becomes 15/60 = 0.25 hour. Distance covered while riding is 0.25(x + 6) = 0.25x + 1.5
Since the distance is the same,then
x = 0.25x + 1.5
x - 0.25x = 1.5
0.75x = 1.5
x = 1.5/0.75
x = 2
her speed on the bicycle is
x + 6 = 2 + 6 = 8 mph
Answer:
C. 40.5 cm²
Step-by-step explanation:
Use the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
The bases are the parallel sides, 4.5 cm and 9 cm. The height is the perpendicular distance between them, 6 cm. Filling in these numbers, we have ...
A = (1/2)(4.5 +9)(6) = 40.5 . . . cm²
Step-by-step explanation:
Given
One plain pizza and two sodas cost $15.95
Similarly, 3 plain pizzas and 5 sodas cost $45.90
Suppose the cost of single pizza and soda be
and ![y](https://tex.z-dn.net/?f=y)
In linear equation format, it can be written as
![\Rightarrow x+2y=15.95\\\Rightarrow 3x+5y=45.90](https://tex.z-dn.net/?f=%5CRightarrow%20x%2B2y%3D15.95%5C%5C%5CRightarrow%203x%2B5y%3D45.90)
Therefore, the above two equations represents the given situation.
