Answer:
The Answer is B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus
(x - 2.5)² + (y - (- 3.5))² = 6², that is
(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle
it takes mrs. jordan 24 minutes to complete 12 questions.
if she completes each question in 1/2 a minute, then:
1/2 / 12 questions = 24 minutes.
First analyze your question. Barbara has a goal to read 45 minutes every day. If she meets her goal, how many minutes will she have read in 360 days?
So....
360*45=16,200
The answer is D. 16,200
Good luck with your studies, I hope this helps!!
Answer:
<h2>
30 cm²</h2>
Step-by-step explanation:
- Area of triangle = 1/2 (base × height)
1/2(12*5)=
1/2*60=
30 cm²
Answer:
Since x= -3y + 6
Substitute this into equation 2
You now have equation 2 as
2(-3y+6) + 8y = -12
-6y + 12 + 8y = -12
8y - 6y = -12 -12
2y = -24
y= -12
x = -3(-12) + 6
x= 36 + 6
x= 42.
