A quantity, t, varies inversely with a quantity, r. Ift = 6, then r = 5.
dexar [7]

Answer:

Step-by-step explanation:

if t varies inversely proportional as r, then,

t ∞ 1/r

t = k.1/r

t = k/r

substitute t =6 and r = 5 into the equation above

6 = k/5

k = 5 x 6 = 30

the equation that represents this variation is given by,

t =30/r

tr = 30

when r =15,

t = 30/15

t =2

Based on the circle graph how many pounds of milk and eggs does the average American consume each year PLS EXPLAIN FOR BRAINLEST
Gnoma [55]

Answer:

H.  552

Step-by-step explanation:

Circle graph information:

  • Milk and eggs = x%
  • Fruits and vegetables = 38%
  • Cereals = 10%
  • Meat and fish = 10%
  • Sugar = 8%
  • Fats and oils = 4%

Total consumption = 1840 pounds per person

First, calculate the percentage of milk and eggs (the value of x).

Total percentages = 100%

⇒ x + 38 + 10 + 10 + 8 + 4 = 100

⇒ x + 70 = 100

⇒ x = 30

Therefore, 30% of food consumption is milk and eggs.

To calculate the number of pounds of milk and eggs the average American consumes each year, simply find 30% of the total consumption:

= 30% of 1840

= 30% × 1840

=\sf \dfrac{30}{100} \times 1840

= 552

Therefore, the average American consumes 552 pounds of milk and eggs each year.
