To get you answer multiply .3 and 2.7
Answer:
See below
Step-by-step explanation:
1) x=2-1
x=1
2) (x+1)(x+1)=2(x+1)
3) 10x-20 -11 = 4+3x
10x-3x=20+11+4
7x=35
x=5
Answer:
29
Step-by-step explanation:
c² = 2² + 5²
c² = 4 + 25
c² = 29
c = sqrt(29)
Answer:
x = 1,092
Step-by-step explanation:
Duck eggs : chicken heads =
2 : 7
Number of duck eggs = 312
Number of chicken eggs = x
Duck eggs : chicken heads = 312 : x
Equate both ratios
2 : 7 = 312 : x
2/7 = 312/x
Cross product
2 * x = 7 * 312
2x = 2,184
x = 2,184 / 2
= 1,092
x = 1,092
Answer:
total area = 18.28 in.^2
perimeter = 16.28 cm
Step-by-step explanation:
Area:
The total area of the figure is the sim of the area of the rectangle and the area of the semicircle.
total area = LW + (1/2)(pi)r^2
total area = (4 in.)(3 in.) + (1/2)(3.14)(2 in.)^2
total area = 12 in.^2 + 6.28 in.^2
total area = 18.28 in.^2
Perimeter:
The perimeter of the figure is the sum of the lengths of the left side, bottom side, and right side of the rectangle and the circumference of the half circle.
perimeter = 3 cm + 4 cm + 3 cm + (1/2)(pi)d
perimeter = 10 + (1/2)(3.14)(4 cm)
perimeter = 10 + 6.28 cm
perimeter = 16.28 cm
