Dominick is training for a race. He spends 0.75 hours running each time he runs and 1.5 hours swimming each time he swims. This week, he spent more than 6 hours training for the race. Which graph represents his possible training times this week?

Answer with explanation:

⇒Let , x duration of hours(1 Duration of Run=0.75 Hours) Dominick Ran this week , and y Duration of Hours(1 Duration of swim=1.5 Hours) Dominick swam this week.

⇒Total time spent by Dominick for the training (Run +Swim) >6

 Writing the Inequality using the variable x and y

→ 0.75 x +1.5 y > 6

\Rightarrow \frac{75 x}{100}+\frac{15 y}{10}> 6\\\\ \Rightarrow 75 x +150 y > 600\\\\\Rightarrow x +2 y>8\\\\\Rightarrow \frac{x}{8}+\frac{y}{4}>1

Drawing the Equation of line which passes through , (8,0) and (0,4) . To draw a Unique line you need  two distinct points:

Put x=0 and , y=0 in the above equation to check whether origin comes under the shaded region or not

L H S

=0+2×0

=0<8(R HS)

So, origin will not come under the shaded Region.

Find the average value of f(x, y = over the region, r, the triangle with vertices (0, 0, (0, 1 and (1, 1.

Can't be done without knowing what f is...

But I can tell you that the average value of f is given by

\dfrac{\displaystyle\iint_Rf(x,y)\,\mathrm dx\,\mathrm dy}{\displaystyle\iint_R\mathrm dx\,\mathrm dy}

At the very least, we can compute the denominator, which is just the area of R. You have

\displaystyle\iint_R\mathrm dx\,\mathrm dy=\int_{x=0}^{x=1}\int_{y=x}^{y=1}\mathrm dy\,\mathrm dx=\int_0^1(1-x)\,\mathrm dx=\dfrac12

so the average value will be

2\displaystyle\iint_Rf(x,y)\,\mathrm dx\,\mathrm dy

An average persons heart beats about 103,680 times a day.Write and solve an equation to find about how many times the average persons heart beats in one minute.

To find how many times an average person's heart beats you will need to divide 103,680 and 60. This is because in 1 minute there is 60 seconds. When you divide this you get 1,728. So the heart beats 1,728 times per minute. For the equation, write 103,680 then division sign, then write 60 then put a equal sign, then write 1,728!

Kaya used 7 cups of flour to bake 5 cakes how much flour on average did she put in each cake ? Write your answer as a decimal.

So I would set up a porportion: 7 cups flour over 5 cakes. 7/5.

Then the other half would be: x cups over 1 cake. x/1

Set the two equal to each other 7/5=x/1

Cross multiply: 5x=7

Divide to solve for x: x=7/5
x=1.4 cups.

So just used about 1.4 cups of flours per cake.

Clifton's family also drove to the camp, but they drove half as far as Priscilla's family. Write a numerical expression to represent the distance Clifton's family drove.

Lets say Priscillas's family total drove P miles.
and Clifton's family drove C miles
now Clifton drove half as far as Priscilla drove.
so C=P/2   this is the expression

If Priscilla drove total 135+40=  175miles
And Clifton drove C=175/2=87.5miles

A helicopter fies east 15 miles then south 36 miles. How far is the helicopter from its original​ position? Use the Pythagorean theorem.

Pythagoras is A squared + B squared= C squared (C is always the slanted side!!)

So you do 15 squared + 36 squared (which is 225+1296)= C squared.
You add A squared and B squared together (which is 1521) then square route that number to get your distance from original position. Hope this helps :)
