Answer:
11,200
Step-by-step explanation:
At first we use "BODMAS" rule.
Given,
(3.5×10^13)-(1.4×10^12)/3×10^9
So, we will break the brackets at first. With the help of excel, we can get the desired result. The following images will show you the step-by-step result.
Use "Number" instead of "general" in the excel sheet. You can use calculator too.
Answer:
80 degrees.
Step-by-step explanation:
Answer:
Consider the expression 
. q is called the quotient, a is is the dividend and b is the divisor.
Since q is a multiple of 6, then q has the form 
for some integer k.
Since a is a multiple of 9, then a has the form 
for some integer s.
Since b is a factor of 12, then if 12 can be expressed of the form 
, for c an integer. Then b has the form 
Replacing the preview expression in the initial expression we obtain:
Then 
is a equation to Isabel's problem.
Answer:
The image of a translation, reflection, or rotation is congruent to the original figure, and the image of a dilation is similar to the original figure. Two figures are similar when one can be obtained from the other by a sequence of translations, reflections, rotations, and dilations.
Eric took 20 hours to do the job alone.
<u>Step-by-step explanation</u>:
<u>Given </u>:
- Total work = 75 packages
- Joe took 5 hours to complete the total work.
The amount of work Joe alone can do per hour = 75/5 = 15 packages.
The amount of work Joe and Eric together do per hour = 75/4 = 18.75
The amount of work Eric alone can do per hour = 18.75 - 15 = 3.75
The time Eric took to complete the entire work = 75 / 3.75 = 20 hours.
