18-(\sqrt[3]{27})^3=18-27=-9

\left(\sqrt[3]{-\dfrac18}\right)^3+3\dfrac34=-\dfrac18+\dfrac{15}4=\dfrac{29}8=3\dfrac58

5\sqrt[3]{729}-24=5\times9-24=21

\dfrac14-2\sqrt[3]{-\dfrac1{216}}=\dfrac14-2\times\left(-\dfrac16\right)=\dfrac7{12}

54+\sqrt[3]{-4096}=54-16=38

4\sqrt[3]{8000}-6=4\times20-6=74

AP and BQ are medians of the triangle ABC and K is the centroid of the triangle.
One of the properties of  the medians is that the point of intersection divides the median in the ratio 2:1

So BK = 2 KQ  therefore 

15 = 2 * KQ 
and KQ = 7.5  answer

The sum of four consecutive integers is 286. Find the four integers
8_murik_8 [283]
Step 1: Write out the problem.
Step 1: Write out the problem.
Step 1: Write out the problem.
x+(x+1)+(x+2)+(x+3)= 286

Step 2: Take out the parentheses.
x+x+1+x+2+x+3= 286

Step 3: Combine like terms.
4x+6= 286

Step 4: Subtract 6 from both sides.
4x+6 -6= 286 -6

Step 5: Divide 4 on both sides.
4x/4 = 280/4

x=70

Which means the answer is 70, 71, 72, 73

Check Work:
70+71+72+73= 286

So this is correct :)

alexdok [17]

Answer:

10 years

Step-by-step explanation:

Given

Decline from (0,h) to (10,0)

See attachment for graph

Required

Determine the age when height = 0

The function of the graph is represented as: (age, height)

So, we need to read from the graph the corresponding value of age (on the x-axis) when height = 0 (i.e. the y-axis)

From the attached graph;

age = 10 when height = 0

<em>Hence, the age of the car is 10 years</em>
