Lets put the problem all together first
1) p^2+mn
2^2+0(-1)
Now we start
2x2=4
0x-1=0
4+0=4
Your answer should be 4:)
2) m+np^2
0+-1(2)^2
2x2=4
-1x4=-4
0+-4=-4
Your answer should be -4:)
Each dress will need 5.4 yards of fabric and the answer lies between 5 and 6
Step-by-step explanation:
Given
Total fabric = 27 yards
Dresses to be made = 5
In order to find the measurement of fabric for one dress, the total fabric will be divided by number of dresses to be made.
So,


The answer lies between the whole numbers 5 and 6
Hence,
Each dress will need 5.4 yards of fabric and the answer lies between 5 and 6

Answer:
- radius: 15 ft
- diameter: 30 ft
- circumference: 30π ft
Step-by-step explanation:
The area is given in terms of the radius as ...
A = πr^2
so we can find the radius as ...
r = √(A/π)
For your circle, the radius is ...
r = √(225π ft^2/π) = 15 ft
The diameter is twice the radius, so is ...
d = 2r = 2·15 ft = 30 ft
And the circumference is π times the diameter:
C = πd = π·30 ft = 30π ft
The answer is 45 degrease
Answer:
Step-by-step explanation:
<u>According to intersecting chords theorem:</u>
- 21(2x - 6) = 30(x + 1)
- 42x - 126 = 30x + 30
- 42x - 30x = 126 + 30
- 12x = 156
- x = 156/12
- x = 13
