Answer:
56 people drink 3 cups daily
Step-by-step explanation:
What's the total number of people that drink 3 cups?
Total number of people = 400
7 / 10 were asked said yes
Number of people that said yes = (7 / 10) × 400 = 280
280 people drink tea.
20% of 280 people drink 3 cups daily, whats the number = ?
20% of 280 = ?
20 / 100 = x / 280
(20 × 280) = (100 × x)
5600 = 100x
X = 5600 / 100
X = 56 people
56 people drink 3 cups of tea daily.
A system of equations with infinitely many solutions is a system where the two equations are identical. The lines coincide. Anything that is equal to
will work. You could try multiply the entire equation by some number, or moving terms around, or adding terms to both sides, or any combination of operations that you apply to the entire equation.
You could multiply the whole thing by 4.5 to get
. If you want, you could mix things up and write it in slope-intercept form:
. The point is, anything that is equivalent to the original equation will give infinitely many solutions x and y. You can test this by plugging in values x and y and seeing the answers!
The attached graph shows that four different equations are really the same.
Answer:
The outside edge is 44 ft longer than the inside edge.
Step-by-step explanation:
The outside edge has a 1000 ft radius. Because the curve makes a 180° turn, the length of the curve is half of the perimeter of a circle.
Perimeter of a circle:
Outside length of the curve is given by:
R=1000 ft
Then,
Inside length of the curve is given by:
r=R-14 ft
The difference between the two lengths is:
The outside edge is 44 ft longer than the inside edge.
Answer:
1 1/3
Step-by-step explanation:
1/3+1/3+1/3+1/3 is 1 and 1/3 cups
The triangle below that would be equivalent to sin of 67 degrees would be answer choice d.12/13.
