To convert mixed fractions to improper fractions:
a b/c=(ac+b)/c so we have:
43/10+127/30+37/15 now making all terms have a common denominator of 30
(43/10)(3/3)+(127/30)(1/1)+(37/15)(2/2)
129/30+127/30+74/30
(129+127+74)/30
330/30
11 acres
Now
11a(25b/a)=275 bags of fertilizer.
Answer:
x=15
Step-by-step explanation:
t=30
30+30=60
120-60=60
4x = 60
60/4 = 15
x=15
Answer:
It is red
Step-by-step explanation:
Answer:
1. 37.0 in²
2. 55 m²
Step-by-step explanation:
1) all angles in an equilateral triangle are 60°
The dotted line is an angle bisector which also divides the triangle into two congruent right angle triangles
Find the base using trig ratio
cos(30) = 8/base
base = 16sqrt(3)/3
Area = ½ × 16sqrt(3)/3 × 8
= 36.95041723 in²
2. d1: 5 + 5 = 10
d2: 3 + 8 = 11
Area = ½ × 10 × 11
= 55 m²
Step-by-step explanation:
(2, 4), (4, 8) and (5, 10) are on the line y = 2x.
Hence they line on a straight line,
The line passes through the origin, and
it shows a proportional relationship.
