Answer:
Distance = ❘-36 - 21❘
Step-by-step explanation:
Given that,
A plane takes off at 21 degrees latitude.
It flies directly south and lands at -36 degrees latitude.
We need to find the expression for the difference in latitude. It can be calculated as follows:
Distance = |-36-21|
= -57
Hence, the correct option is (A).
Answer:
a. 17
b. 30
c. 5
Step-by-step explanation:
English (E) = 28 - 15 (10+8-3) = 13
Amharic (A) = 30 - 10 (8+5-3) = 20
Afan Oromo (AO) = 42 - 12(10+5-3) = 30
E+AO = 10
E + A = 8
A + AO = 5
A + AO + E = 3
a. 13 people spoke just English+ 20 people who just spoke Amharic + 30 people who just spoke Afan Oromo+ The multilingual people (10+8+5-3=20) which is 83, so that means that 17 learned no language.
b. 42 People learned Afan Oromo, but only 30 of them learned that language separately. 10 People learned it along with English, and 5 learned it with Amharic. However, 3 of those people were the same, so 12 people of those 42 spoke multiple languages. Therefore, only 30 people spoke just Afan Oromo.
c. This one is kinda just a trick question, they want you to overthink it because of the 3 who learned all, but it's just 5 like it says in the question.
Answer:
10 minutes on stationary bike
30 minutes on elliptical trainer
Step-by-step explanation:
set up a system of equations:
8t+6b=300
t+b=40
*let t represent elliptical trainer, and let b represent stationary bike
solve by substitution:
8t+6b=300
t=40-b
8(40-b)+6b=300
320-8b+6b=300
-2b=-20
b=10
so, you should spend 10 minutes on the stationary bike
to find how long you should spend on the elliptical trainer:
t=40-b
t=40-10
t=30
so, you should spend:
10 minutes on stationary bike
30 minutes on elliptical trainer
Answer:
A line graph (also known as a line plot or line chart) is a graph which uses lines to connect individual data points that display quantitative values over a specified time interval. Line graphs use data point "markers" that are connected by straight lines to aid in visualization.
Answer: radius = 10 cm.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder = π r² h
Where:
r = radius
h = height
Replacing with the values given:
3768 =π r² 12
Solving for r
3768/ (12π) = r²
99.95 = r²
√99.95 = r
r = 9.99 ≅ 10 cm (rounded)
