How do you write 35 over 20 As a percentage
lara31 [8.8K]
In order to write \frac{35}{20} as a percentage, we must first convert the fraction into a decimal. We can do that simply by dividing.

35 / 20 = 1.75

In order to convert a fraction to a decimal, we must multiply it by 100

1.75 * 100 = 175%

\frac{35}{20} as a percentage is 175%.
Hope that helped =)

2x + y - z = -8
Andreyy89

Answer:

Multiply row 1 by \frac{1}{2}.

Step-by-step explanation:

The augmented matrix of the system of linear equation is described below:

\left[\begin{array}{cccc}2&1&-1&-8\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]

Where a_{11} = 2, if we need to create a_{11} = 1, we need to multiply row 1 by \frac{1}{2}, that is to say:

\left[\begin{array}{cccc}1&\frac{1}{2} &-\frac{1}{2} &-4\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]

Hence, the correct answer is: Multiply row 1 by \frac{1}{2}.

Two airplanes are are 1600 miles apart and heading toward each other at different altitudes. The first plane is traveling north
Elden [556K]

The planes will pass each other in 1.14 hours.

Why?

To solve the problem, we must remember that since both planes are heading toward each other, the speed to the calculations will be their combined speeds.

The speed will be:

Speed=PlaneA+PlaneB\\\\Speed=620mph+780mph=1400mph

Now, calculating the time, we have:

x=v*t\\\\1600mi=1400mph*t\\\\t=\frac{1600mi}{1400mph}=1.14hours

Hence, the planes will pass each other in 1.14 hours.

Have a nice day!

Mrs. Frank earns $528 per week from which 40% income tax is deducted. Calculate her net pay.​
Zina [86]

Answer:

\$316.80\:\text{a week}

Step-by-step explanation:

If a 40% income tax is deducted from Mrs. Frank's income, her total/net income will be 60% of her income before income tax.

Therefore, her net pay is equal to 528\cdot 0.6=\boxed{\$316.80\text{ a week}}.
