This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g
Answer:
32b<1500
Step-by-step explanation:
a. the can spend up to 1500 but not more so it has to be less
b= 46 bats
46x32= 1472<1500
18/10
9/5
Anything along those lines!
Answer:
C. Both of the above answers
Step-by-step explanation:
13 = -6(-2) + 1
13 = 12 + 1
13 = 13
7 = -6(-1) + 1
7 = 6 + 1
7 = 7
Step-by-step explanation:
Hypotenuse : Opposite the right angle.
Opposite : Opposite the angle.
Adjacent : the last side left.
Your formulas.
Soh Cah Toa (Sin Cos Tan)
You'll be using Cos (Cah) because hypotenuse and adjacent are the only sides with something in it.
You rearranged formula :
Side length × Cos (Angle) = your answer to x
