Remark

He's very lucky to be alive.

Givens

distance = d = 0.8 miles

Rate = r = 0.0321 mi per minute

Time = t = ??

Formula

d = r * t

Solve

0.8 = 0.0321 * t Divide by 0.0321

0.8/0.0321 = t

t = 24.92 minutes <<<< Answer

0.0321 miles per minute, simply means, in 1 minute, it does 0.0321 miles.

$\bf \begin{array}{ccll}
miles&minutes\\
\cline{1-2}
0.0321&1\\
0.8&x
\end{array}\implies \cfrac{0.0321}{0.8}=\cfrac{1}{x}\implies 0.0321x=0.8
\\\\\\
x=\cfrac{0.8}{0.0321}\implies x\approx 24.92211838$

What is the first step in writing f(x) = 6x2 + 5 – 42x in vertex form?

atroni [7]

If we want to write the function in vertex form:
f ( x) = 6 x² + 5 - 42 x = 6 x² - 42 x + 5 = 6 ( x² - 7 x ) + 5 ...
First step is: C ) write the function in standard form ( y = ax² + b x + c )

Aunt Thelma planted an herb garden. She planted rosemary in 2/9 of the garden. She

Reptile [31]

Answer:

$\dfrac{17}{45}$

Step-by-step explanation:

Fraction on which Rosemary was planted $=\dfrac{2}{9}$

Fraction on which dill was planted $=\dfrac{2}{5}$

Let the fraction on which chives was planted=x

Then:

$\dfrac{2}{9}+\dfrac{2}{5}+x=1\\$Since the LCM of 9 and 5 is 45\\We multiply all through by 45\\45\left(\dfrac{2}{9}\left)+45\left(\dfrac{2}{5}\right)+45x=45(1)$\\10+18+45x=45\\45x=45-28\\45x=17\\Divide both sides by 45\\x=\dfrac{17}{45}$

The fraction of the garden on which Chives was planted is $\dfrac{17}{45}$

The parallelogram shown below has an area of 404040 units^2 2 squared.

TEA [102]

Question:

The parallelogram shown below has an area of 40 units squared.

Find the missing base.

Answer:

See Explanation Below

Step-by-step explanation:

The question is incomplete as the diagram which shows the dimension of the parallelogram is not attached.

However, I'll give a general explanation on how to get the base of the parallelogram. If you follow this explanation, you'll get the right answer regarding your question.

The area of a parallelogram is calculated as thus.

Area = Base * Height

Given that the area = 40 units²

Let's assume the height of the parallelogram is 10 unit.

All you need to do is to plug in these values in the formula above..

Area = Base * Height becomes

40 = Base * 10

Divide both sides by 10

40/10 = Base * 10/10

4 = Base

Hence, Base = 4 units

Or take for instance the height is 5 units.

You'll still follow the simple steps as it is above.

Area = Base * Height becomes

40 = Base * 5

Divide both sides by 5

40/5 = Base * 5/5

8 = Base

Hence, Base = 8 units
