Answer:
24 1/2 minutes
Step-by-step explanation:
10 problems in 7 minutes
5 problems in 3 1/2 minutes
multiply 5 × 7 (5×7 = 35) to get 35
multiply (or add) 3 1/2 minutes times 7 (or add it together 7 times
Answer:
see attached
Step-by-step explanation:
This is a difficult graph to make, because none of the points are on any grid intersections.
At the left (s=0), it starts 1/4 of the distance up from 7000 toward 8000.
At the right (s=10), it crosses 3/10 of the distance up from 9000 toward 10,000.
From the plot, the masses of the five smallest sodium chloride samples are all 1/4 ounce. Therefore, we can calculate for their total mass by multiplying the mass by 5:
total mass = 1/4 ounce * 5
= 5/4 or 1.25 ounces
We can get the same result even if we compute for the total mass by taking the sum of their masses:
total mass = 1/4 + 1/4 + 1/4 + 1/4 + 1/4
= 5/4 oz.
Answer: 281.1 degree
Step-by-step explanation:
Given that a jogger leaves his house runs 15 km on a straight track in a North westerly direction to a lake. The lake is 2.9 km north of the joggers house.
Using pythagorean theorem to find the third side, which is 14.72
The angle at the lake side will be achieved by using sine rule.
