Answer:

$6,000

Step-by-step explanation:

If y is the amount of money a child receives, and x is the total amount being divided among the children, then

Jane's share:  y = \frac{4}{4+5+7} * x = \frac{4}{16}x

Peter's share:  y = \frac{5}{4+5+7} * x = \frac{5}{16}x

Martha's share:  y = \frac{7}{4+5+7} * x = \frac{7}{16}x

We know Jane got $2000, so we can use that to solve for x:

\frac{4}{16} x = 2000

x = \frac{16}{4} * 2000 = 8000

Plug this x value in to find how much Peter and Martha received:

\frac{5}{16} * 8000 + \frac{7}{16} * 8000 = $6000

Find the 6th term of the geometric sequence, given the first term and common ratio a1= 5 and r=3/2
uysha [10]

<u>Answer</u>



37.96875



<u>Explanation</u>

In geometric sequence we use the formula below to find the nth of a sequence.


Tn = ar⁽ⁿ⁻¹⁾

Where a ⇒ first term

n ⇒ the term we are looking for

T₆ = 5 × (3/2)⁶⁻¹

= 5 × (3/2)⁵

= 5 × 243/32

= 1215/32

= 37 31/32

= 37.96875

An apple crisp recipe calls for 90 grams of white sugar and 55 grams of brown sugar. How many kilograms of sugar, including both
denis-greek [22]
90 grams are equivalent to 0.09 kilograms and 55 grams are equivalent to 0.055.
So 0.09 + 0.055 = 0.145.
0.145 * 12 = 1.74
So 1.74 kilograms of sugar is needed to make 12 crisps.
