Mathematics

zvonat [6]2 years ago
8 0

Answer:

There is 80 people still at the party

Step-by-step explanation:

To find how many people are still at the party we first have to find how much 1/3 of 120 is.

∴120/3=40

then we subtract 1/3 of 120 from 120 to get the answer

∴120-40=80

Arlecino [84]

Answer:

200 kilometers

Step-by-step explanation:

since the driver goes 50 kilometers at a constant rate for 4 hours, you multiply it by 4, and you get 200.

An easy way to multiply these numbers is to multiply the 4 and 5, which equals 20, then add the extra zero from the 50.

James earns $418 per week and has one exemption. His office’s payroll software is broken and can only compute the withholding fo
user100 [1]

James should earn a <em>weekly</em> salary of $ 432.76 with 0 exemptions to give the closest exemption.

<h3>How to estimate the salary without exemption</h3>

In this question, we should estimate the salary <em>earned</em> before one exemption and find the <em>equivalent brute</em> salary with no exemptions. The expected salary is equal to product the <em>brute</em> salary minus the product of the <em>tax</em> rate and <em>brute</em> salary.

According to the table we have the expected salary after one exemption:

x = 418\cdot \left(1-\frac{19.66}{100} \right)

x = 335.82

After a quick inspection to the <em>salary</em> column for zero exemptions, we find that percentage associated to a salary with no exemptions: (r = 22.40\,\%)

C = \frac{335.82}{1-\frac{22.40}{100} }

C = 432.76

James should earn a <em>weekly</em> salary of $ 432.76 with 0 exemptions to give the closest exemption. \blacksquare

<h3>Remark</h3>

The exemption table is missing. The complete figure is shown below.

The equation d = 3t gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.
Natasha_Volkova [10]

Answer:

Liam's rate = 3 meters per second

Edgar's rate = 3.2 meters per second

Edgar swims faster

Step-by-step explanation:

<u>Liam:</u>

The equation d=3t gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.

When t=0,\ d=0.

When t=1,\ d=3.

Rate of change:

\dfrac{3-0}{1-0}=3

Liam's rate is 3 metres per second.

<u>Edgar:</u>

When t=20, \ d=64.

When t=40,\ t=128.

Rate of change:

\dfrac{128-64}{40-20}=\dfrac{64}{20}=3.2

Edgar's rate is 3.2 metres per second.

Edgar swims faster.
