Answer:
9) 51 × 10⁻⁵ = 0.00051
10) Cash price = #54,000 × (1 - 0.125) = #47,250
11) -40·p·q÷(-2)² = -10·p·q
12) 0.003 × 0.045 = 1.35 × 10⁻⁴
13) N40°W = 320°
14) The base diameter of the cylinder = √(4 × (700×π cm³/7)/π) = 20 cm
15) The LCM of 2·x²·y, 3·x·y² is 12·x²·y²
16) 636,000 = 6.36 × 10⁵
17) 1/3·π·r²·h₁ = π·r²·h₂
h₂/h₁ = 1/3·π·r²/( π·r²) = 1/3
h₂/12 = 1/3
h₂ = 12/3 = 4 cm, the height of the cylinder = 4 cm
18) The angle = 180 + 45 = 225°
19) The total surface area = 22/7×14²/4 + 22/7 ×14 × 20 = 1034 cm²
20) The number is 58/2 = 29.
Step-by-step explanation:
Answer:
4/6 6/9 8/12 10/15 and so on, just multiply both the numerator and denominator by the same number and get your answer.
Step-by-step explanation:
So,
The chart tells us that the people that registered for soccer is 45.
The chart also tells us that the people that registered for basketball is 35.
45 - 35 = 10
10 more people registered for soccer than for basketball.
3+8=11
11 units
99=11 units
divide by 11 both sides
9=1 unit
plums=8 units
8*9=72
72 plums
Answer:
See below.
Step-by-step explanation:
top left
9 × 9 = 81
9/81 = 1/9
top right
9 × 9 = 81
36/81 = 4/9
bottom left
6/72 = 1/12
bottom right
12/72 = 1/6
