Answer:
a=25
angle abq=139 degrees
bcr=41
Step-by-step explanation:
(2a-9)+(5a+14)=180
7a+5=180
7a=175
a=25
2(25)-9=41
180-41=139
angle abq=139 degrees
bcr=41
Answer:
A = 3.14 yd^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
Letting pi be approximated by 3.14
6.28 = 2 * (3.14) *r
6.28 = 6.28 r
Divide each side by 6.28
6.28/6.28 = 6.28r/6.28
1=r
We can find the area by
A = pi r^2
A = 3.14 (1)^2
A = 3.14
Y= 2x + 1, hope this helps
Since 1 batch needs 1 1/2 cups. You simply have to multiply 1 1/2 x 3.
4 1/2 cups are needed to bake 3 batches.
