Answer:
D) 11
Step-by-step explanation:
If you start at five and count back on each little x
than you should come up with 11
0=3
1=1
2=2
3=4
4=1
3+1+2+4+1=11
You do This because you need to find how many has fewer so you don't count 5
Answer:
x=a/(y-k)+h
Step-by-step explanation:
y-k=a/(x-h)
(y-k)(x-h)=a
xy-hy-kx+kh=a
xy-kx=a+hy-hk
x(y-k)=a+h(y-k)
x=a/(y-k)+h
Answer:
b. 7x + 2.8y
Step-by-step explanation:
distribute the negative sign:
= -2x + 8.1 + -1(-9x + 5.3y)
= -2x + 8.1 + -1(-9x) + -1(5.3y)
= -2x + 8.1 +9x + -5.3y
combine like terms:
= (-2x + 9x) + (8.1 + -5.3y)
= 7x + 2.8y
Answer:
77.3
Step-by-step explanation:
Decimal notation: 77.3
No. of significant figures: 3
No. of decimals: 1
Scientific notation: 7.73 × 101
Steps:
#1: 77.3003 (the original number has 6 sig figs)
#2: 77.3 (rounded to 3 significant figures)
Area of the figure = 112 in²
Solution:
The given figure is splitted into two shapes.
One shape is square.
Each side of square are equal.
Side = 10 inch
Area of the square = side × side
= 10 × 10
= 100
Area of the square = 100 in²
The other shape is triangle.
Base of the triangle = 10 in – 6 in = 4 inch
Height of the triangle = 16 in – 10 in = 6 inch
Area of the triangle = 

= 12
Area of the triangle = 12 in²
Area of the figure = Area of the square + Area of the triangle
= 100 in² + 12 in²
Area of the figure = 112 in²
Therefore, area of the given figure is 112 in².
