Call x the number of children.

originally each got $240/x

but later one part was redistributed so each of the (x-1) children got $240/(x-1).

We also know that $240/(x-1) = $240/x + $8. that is our equation to solve for x.

240x = 240*(x-1)+8x(x-1)

240x = 240x - 240 + 8x^2 - 8x

8x^2 - 8x - 240 = 0

this is a quadratic equation with two solutions. you get the solutions using a formula (of your preference). On my end I got the two solutions as x1=-5 and x2=6.

Clearly the solution (number f children) can't be negative, so the one practical solution is x=6 which is the number of  children in the Kind family.

The answer choice which represents the group which makes up the best sample for the researcher's survey as described in the task content is; Choice A; Parents of preschool children.

<h3>Which answer choice best represents a sample for the intended survey by Mrs Greenaway's researcher?</h3>

It follows from the task content that; Mrs. Greenaway has decided to open a new preschool in her town.

The need for a researcher therefore arises from the decision to either open the preschool or not.

Consequently, in a bid to choose a sample, Mrs. Greenaway's researcher must make sure the sample chosen is from the population space.

Therefore, answer choice A represents the correct sample.

Given the following :

Temperature in Antarctica = - 121 Fahrenheit

Temperature in Sahara desert = 132 Fahrenheit

Number of degrees in which Sahara desert is warmer than Antarctica :

(temperature in Sahara desert - temperature in Antarctica)

= ( 132°F - (-121°F))

= (132°F + 121°F)

= 253°F

Sahara Desert is 253°F warmer

Andre can run 5 miles in 40 minutes. At that rate of speed, how long would it take him to run 10 kilometers? Use the conversion
matrenka [14]

Answer:

50 minutes = B

Step-by-step explanation:

Andre can run 5 miles in 40 minutes

for 1 miles = 40/5 = 8 minutes

  • for 10 kilometres

1 mile = 1.61 kilometres

x = 10 kilometres

x= (10x1)/1.61= 10/1.61 = 6.21miles

  • for 1 miles = 40/5 = 8 minutes
  • 6.21 miles = 8 x 6.21 = 49.689 minutes ≈ 50 minutes = B
