4. A) 95°
5. B) 49°
You add
46° + 39° = 85°
180° - 85° = 95°
You add
89° + 42° = 131°
180° - 42° = 49°
Hope this Helps!!
V=lwh
v=12
l=3
w=2
h=h
12=3*2*h
12=6*h
divide both sides by 6
2=h
surface aera=2(LW+LH+WH)
L=3
w=2
h=2
SA=2(3*2+3*2+2*2)
SA=2(6+6+4)
SA=2(16)
SA=32
Minimum is 32 ft²
Hope this helps :)
In order to find the unit rate of acres per day, or in other words, how many acres can they plant in one day, you must divide 5/8, the number of acres planted, by 4/5, the number of days it took to plant. When you divide the two fractions, first set up an expression:
5/8<span>÷4/5
Then, to make things simpler, turn the division expression into a multiplication statement so that you have 5/8*5/4. Then multiply straight across and you get your answer as 25/32. This means that the workers can plant 25/32 acres per day.</span>
Answer: Robert's present age is 10 years
Robert father's present age is 40 years
Step-by-step explanation:
Let r = Robert's current age
Let y = Robert father's current age
Robert's father is 4 times as old as robert. This means that
y = 4x
After 5 years, Robert's father will be three times as old as Robert. This means that
y + 5 = 3(x+5)
y + 5 = 3x + 15 - - - - - - - ;1
We will substitute y = 4x into equation 1. It becomes
4x + 5 = 3x + 15
Collecting like terms,
4x - 3x = 15 - 5
x = 10
y = 4x
Substituting x = 10,
y = 4× 10 = 40 years
