Answer: She cycles 25% of the time

Step-by-step explanation:

From the question, Sally walks 15% of the time.

She drives 3/5 of the time.

We then convert 3/5 to percentage.

Converting to percentage means multiplying by a factor of 100.

Hence, Sally drives 3/5*100 = 60% of the time.

If Sally walks 15% of the time and drives 60% of the time, adding up the percentage time used by these two media of transportation will give us

60% + 15% = 75%

Hence if she cycles for the remainder of the time, expressing it as percentage would mean subtracting the time used in other means by 100%

Hence it will be 100% - 75% = 25%

Write in vertex form (by completing the square)y=4x2+40x+96
Anestetic [448]
y=4x^2+40x+96\\ \\ The \ vertex \ form \ of \ the \ function \ is: \\ \\y = a(x - h)^2 + k \\ \\vertex =(h, k) \ is \ given \ by: \\ \\h = \frac{-b}{2a} , \ \ \ k = c -\frac{b^2}{4a} \\ \\a=4 , \ \ b=40 , \ \ c=96

h = \frac{-40}{2 \cdot 4}=\frac{-40}{8}=-5 \\ \\ k = 96 -\frac{40^2}{4 \cdot 4} =96-\frac{1600}{16} =96-100=-4 \\ \\ y = 4(x - (-5) )^2 + (-5)=4(x +5 )^2 -5

6 is 4% of what<br> number?
Ahat [919]

Answer:

150

Step-by-step explanation:

since 4 percent would have to be multiplied by 25 to get 100 you have to multiply 6 by 25. This comes out to 150. You can even check this by doing 150 times 0.04 which is 6 so we are correct!

Find the sum of (–4 + i) and (10 – 5i). –3 + 5i –3 – 5i 6 – 4i 6 – 6i
MaRussiya [10]

Answer:

The answer is 6 – 4i

Step-by-step explanation:

Complex values:

Have the following format: a + bi

In which a is the real part and b is the complex part.

Addition:

Suppose we are going to add two complex numbers. We add their real parts, and their complex parts separatly.

So

(–4 + i) + (10 – 5i) = (-4 + 10) + i(1-5) = 6 - 4i

The answer is 6 – 4i
