Achalk company gets an order for 3000 boxes of chalk at the beginning of the school year, the largest order they have ever received. each box contains 145 grams of chalk. if the efficiency of their chalk production process is 82% and the theoretical yield of the production process is 400,000 grams, will they make their goal?

Given that the efficiency of chalk production is 82 %

We can calculate the efficiency of chalk production using the formula,

% Efficiency

Calculating actual yield from % efficiency an theoretical yield:

82 %

Actual yield =

Each chalk box has 145 g chalk

Number of boxes =

The goal of the chalk box company is to prepare 3000 boxes of chalk. So, the company will not be able to reach the goal as it can just prepare 2262 boxes when the efficiency is 82 %

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
