I believe it is A
Because his initial starting point is 12 and then 1.5x to increase and reach his goal of 26
3x + 6 - 2X + 7. 3X -2X +6+7. X + 13
Answer:
Water level in the reservoir is falling at the rate of 0.398 ft per minute.
Step-by-step explanation:
From the figure attached,
Water level in the reservoir has been given as 10 feet and radius of the reservoir is 4 feet.
Let the level of water in the reservoir after time t is h where radius of the water level becomes r.
ΔABE and ΔCDE are similar.
Therefore, their corresponding sides will be in the same ratio.
--------(1)
Now volume of the water V =
From equation (1),
V =
V =
Since feet³ per minute and h = 5 feet
feet per minute
Therefore, water level in the reservoir is falling at the rate of 0.398 feet per minute.
Answer:
A)let x be the length of one side , 6 × x= peri.
B)6 × 11 = 66
3/4 * 5= 3 3/4 cartons. You can’t buy 3/4 of a carton so Grandma would need to buy 4 cartons of all-purpose cream.
2/3 * 5= 3 1/3. But you can’t buy 1/3 of a carton, so grandma needs to buy 4 cartons of condensed milk.
All together, Grandma needs to buy 4 cartons of all-purpose cream and 4 cartons of condensed milk to make 5 fruit cakes.
