Your father is planning to cook for 35 people using a recipe that specifies two and a half cups of sugar for each six people,

almond37 [142]

Your father will require 14.6 cups of sugar for the larger group

<h3>Ratio and proportions</h3>

From the question, we have that 2.5 cups of sugar can be used to make recipes for 6 people that is;

6 people = 2.5 cups of sugar

In order to calculate for 35 people, we will have;

35 people = x

Taking the ratio of the expressions

6/35 = 2.5/x

6x = 87.5

x = 87.5/6

x = 14.6

Hence your father will require 14.6 cups of sugar for the larger group

D'John saves $8 per week. Arthur saves 4 times the amount D'John saves in the same week. Write an equation that shows how to fin

maw [93]

The variable 'a' represents how much Arthur saves. Because D'John saves $8 per week (7 days), he saves $56. Arthur saves four times more than D'John so $56*4 equals Arthur's total savings for the week; $224. a=$8(7)*4 a=$56*4 a=$224

Ms. Colunga bought a new car, which cost him $30,000. Which equation represents how long it will take for the value of the car t

EastWind [94]

Answer:

3.5 years.

Step-by-step explanation:

The formula for depreciation is as follows (I had to look it up too):

worth after time = initial worth * (rate)^t

In this case it depreciates which means that the rate is 1-0.18 = 0.82.

we know it will be worth 15,000,

So substituting would give us

$15,000= 30,000(0.82^{t})$

now we we need to solve for t, so we will end up with

1/2 = 0.82^t

log (1/2) = t log(0.82)

t = $\frac{log(1/2)}{log(0.82)}$

Therefore, t is roughly 3.5 years.

Great question, hope this helps.
