Answer:
ans=97
Step-by-step explanation:
(i)u should use BEDMAS RULE.
122-4(6)+1
=122-24+1
=122-25
=97
Comparing the given equation to the standard form for the equation of a circle,
(x -h)² + (y -k)² = r²
we find that
h = 0
k = -9
r = 5
The circle is centered at (h, k) = (0, -9). It has radius 5.
Answer:
Let Hassan score be X
Then Dionnie score will be X + 4
: the sum of Hassan and Dionnie is 180
X + ( X + 4 ) = 180
X + X + 4 = 180
COLLECTING LIKE TERMS
2X = 180 – 4
2X = 176
DIVIDING EACH TERM BY 2
2X/2 = 176/2
X = 88
: Hassan scored 88 and Dionnie score 92
Step-by-step explanation:
Answer:
600ft^2
Step-by-step explanation:
Because we are rounding the dimensions to the nearest ten this means the length of 29ft because 30ft and the width of 22ft is 20ft
Area = l X w
Area = 30 X 20
Area = 600
Therefore an estimate for the area of the wall is 600ft^2
Answer:
x = 3, JL = 17, MN = 13
Step-by-step explanation:
Given 2 intersecting chords in a circle , then
The product of the parts of one chord is equal to the product of the parts of the other chord, that is
14x = 7 × 6 = 42 ( divide both sides by 14 )
x = 3
Then
JL = x + 14 = 3 + 14 = 17
MN = 6 + 7 = 13
