The iceberg will weigh 35000 tonnes correct to 2 significant figures.
Depreciation refers to when the value of something goes down over time. The value of a car usually decreases in value with time. Therefore, its value is said to depreciate.
Given that, it is estimated that an iceberg weighs 84000 tonnes. As the iceberg moves into the warmer water, its weight decreased by 25% each day.
Depreciates by 25%, so 100% - 25% = 75%
75% of, 84000 for 3 days:
= (75 / 100)³ × 84000
= (0.75)³ × 84000
= 35437.5
Therefore, the iceberg will weigh 35000 tonnes correct to 2 significant figures.

According to the model, how many more pizzas are sold for each additional coupon issued?
1 pizzas
3.4 pizzas
4.3 pizzas
43 pizzas
46 pizza
Answer:
B. 3.4 pizzas.
Step-by-step explanation:
We have been given a scatter plot, which represents the number of pizzas (y) sold during weeks when different numbers of coupons (x) were issued. The equation represents the linear model for this data:
We can see that our given equation is in form of slope intercept form: , where m= slope of line and b = y-intercept.
We can see from our given equation that y-intercept is 43, when no coupons were issued, there were 43 pizzas sold. 43 is constant and it will not change by any change in x.
The slope of our line is 3.4, which represents change in number of pizzas with respect to change in number of coupons issued. Therefore, 3.4 more pizzas are sold for additional coupon issued and option B is the correct choice.
