Answer:
The dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.
Step-by-step explanation:
Since an artist combines copper and other metals to make bronze, and a bronze sculpture of a dolphin contains 43 g of copper for every 7 g of other metals, while a bronze sculpture of a bird contains 83 g of copper for every 17 g of other metals, to determine which sculpture is more coppery the following calculation must be performed:
Dolphin:
43 + 7 = 50
50 = 100
43 = X
43 x 100/50 = X
86 = X
Bird:
83 + 17 = 100
100 = 100
83 = X
83 x 100/100 = X
83 = X
Therefore, the dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.
Answer:
Where d is the distance traveled, r is the rate, and t is the time. ... It took Markus half an hour to drive home from work. ... 17. Markus lives 17 miles from work. ... What was his average speed in kilometers per hour? ... per hour, we divide by 60 to find out how many hours it took. t = 20 minutes / 60 minutes per hour. = 1/3 hours.
Step-by-step explanation:
The answer is c, the average systolic blood pressure of all USA men aged 40-59
If the slope of the number is positive (the graph goes upward from left to right), then m will be positive, but if the slope is negative (the graph goes downward from left to right), then m is negative. So, no. M does not have to be a positive number, it may also be negative.
% = (Change/Original) * 100
= (6/24) * 100
= (0.25) * 100
= 25%
