The question asks us to find the area of a circle, which can be represented by the formula
. We are told to use
for pi, but we still have the 'r', which represents the radius. To find the radius, we halve the given diameter, giving us
. When we plug in all of our derived values into the formula, we get that the area of the circle is approximately
. Hope this helped and have a great day!
Answer:
10
Step-by-step explanation:
The total parts are:
8 + 5 + 2
= 15
Divide 75 with 15.
= 5
Multiply the ratio with 5.
8×5:5×5:2×5
40:25:10
The smallest share is 10.
Answer:
where denotes speed of the car
Step-by-step explanation:
Given: The speed limit on a city street is 35 kilometers per hour.
To write and graph: an inequality to describe a car’s possible speed.
Solution:
Let the speed of a car be kilometers per hour.
As the speed limit on a city street is 35 kilometers per hour,
First draw the graph of (see figure a.)
Plot the points
Take a point on the left side of line x = 35 say and put it in
which is true.
So, shade the graph on the left side of line x = 35
See the graph b.
the pink part represents the inequality
Step-by-step explanation:
3n-7n-n = 15
5n = 15
n = 15 ÷ 5
n = 3
Answer:
The answer is x = 3 and y = -1
Step-by-step explanation:
If you were to graph the two lines, their equations would be y = x - 4 and y = -x + 2. The two lines intersect at the point (3, -1), so the solution to the system is x = 3 and y = -1.
