A triangle has sides that measure 2 units, 5 units, and 5.39 units. What is the area of a circle with a circumference that equals the perimeter of the triangle? Use 3.14 for π, and round your answer to the nearest whole number.
39 units2
25 units2
49 units2
12 units2
Answer:
12units²
Step-by-step explanation:
Given a triangle that has sides that measure 2 units, 5 units, and 5.39 units,
Perimeter of the triangle = 2 + 5 + 5.39
Perimeter of the triangle = 12.39units
since the circumference is equal to the perimeter of the triangle, hence;
C = 12.39units
C = 2πr
r is the radius of the circle
12.39 = 2(3.14)r
12.39 = 6.28r
r = 12.39/6.28
r = 1.973 units
Get the area
Area = πr²
Area of the circle = 3.14(1.973 )²
Area of the circle = 3.14(3.892)
Area of the circle = 12.22units²
Area of the circle ≈ 12units²
Answer:
D. 12 units2
In GeoGebra, you should see a sketch of William’s kite. You’ll use the sketch to find the lengths of the dowels needed to make the kite. William has indicated that he would like the kite to be AD = 120 cm wide across the bottom, which is labeled on the sketch. Using the width of the kite and the fact that the kite is made from two congruent right triangles, what is AC?
Answer:
60
Step-by-step explanation:
i added a comment instead of a answer so yeah
Answer:
60 cm
Step-by-step explanation:
AD = 120cm
AC = 1/2 AD = 1/2(120) = 60 cm

The average of a list of 4 numbers is 90.0 . A new list of 4 numbers has the same first 3 numbers as the original list, but the fourth number in the original list is 80 , and the fourth number in the new list is 96 . What is the average of this new list of numbers?
Answer:
94
Step-by-step explanation:
Average = sum of numbers / number of items in the set
for the first list, the average is 90 and there are four numbers, the sum of the numbers is 90 x 4 = 360
If the 4th number is 80, the sum of the first 3 numbers = 360 - 80 = 280
so the sum of the first three numbers on the second list is 260. The fourth number is 96. The sum of the numbers = 280 + 96 = 376
Average of the new list = 376 / 4 = 94
when i subtract, wouldn’t you subtract it from 180.
Answer:
Yes you would
Step-by-step explanation:
Answer:
B = 285°
Step-by-step explanation:
What you would actually do is subtract 75° from 360° since the arrow indicates it's looking for the outside measure of the angle. Drawing a circle around would be 360° all the way around.
360° - 75° = 285°
Thus, 285° is the answer for B.

6x+ 21
Step-by-step explanation:
Find the area of the whole thing
find the are of the small shape
minus this from the whole thing
whole thing = (x+5)(x+5) = x^2+ 2x+ 25
small = (x-2)(x-2) = x^2 -4x +4

Explain whether the graph represents a function.
Answer:
The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.

Answer:
Initial value: 2; rate of change: 1
Step-by-step explanation:
The line crosses the y-axis at (0,2) so we know that our initial value is 2. The line follows a pattern of (up 1 over 1) so we know that our rate of change is 1/1, or 1.

At 10 AM, one share of Starbucks stock was $35. By 2 PM the price was $41. The rate the Starbucks stock value was changing is - per hour
Answer:
1.50$
Step-by-step explanation:
difference in money amount: $6
difference in hours: 4
6 divided by 4 equals 1.50.
1.50 times 4 equals 6, hence its 1.50 per hour.
The rate of change in the Starbucks stock value is 150%.
Given that, At 10 AM, one share of Starbucks stock was $35. By 2 PM the price was $41.
We need to find the rate the Starbucks stock value was changing is - per hour.
What is the rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Now, the difference in money=41-35=$6
The number of hours between 10 AM to 2 PM is 4 hours.
The rate of change = The difference in money/Number of hours × 100
=6/4 × 100
=150%
Therefore, the rate of change in the Starbucks stock value is 150%.
