Answer:
Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.
Step-by-step explanation:
we have
Hiroshi's work
Remember that
a negative number is just a positive number multiplied by -1
and (-1)(-1)=+1
so
Correct work
therefore
Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.
Answer:
Julie's share of the profits is (6/16)($4000) = $1500
Step-by-step explanation:
Write and solve an equation of ratios:
Jane's contrib. $10000 10
---------------------- = -------------- = ------ .
Julie's contrib. $6000 6
Adding 10 and 6 together, we get 16.
Julie's share of the profits is (6/16)($4000) = $1500. Jane would take (10/16)($4000), or $2500.
Answer:
<u><em>What is the importance of polynomial functions?</em></u>
<u><em>
</em></u>Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.

Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.
Answer:
9425
D
Step-by-step explanation:
They are in the third tax bracket down. That means that their joint income is over 67900 but less than 137050.
The base rate is 9350. But they are 68200 - 67900 = 300 over the minimum.
So 25% of that 300 is also to be paid to the government 25/100 * 300 = 75 dollars
Now they must pay 9350 + 75 = 9425
