Answer:
1) A
2) I
3) G
4) B
Step-by-step explanation:
1)
Bottom side: 7c - 1
Tall side: 6c + 2
P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2
P = 26c + 2
2)
P = 26c + 2
P = 26(5) + 2
P = 132
3)
P = 2(l + w)
P = 2(3d - 2 + 5d + 1)
P = 16d - 2
4)
P = 16d - 2
P = 16(3) - 2
P = 46
Answer:
8
Step-by-step explanation:
-2 x -2 = 4
4 - (-28 / 7 = -4)
4- -4 = 8
Answer:
%P = 8%
the percentage of fat in the mixture is 8%
Step-by-step explanation:
Given;
The percentage of fat in the mixture is;
%P = total mass of fat in mixture/total mass of mixture × 100%
%P = F/T × 100% ….....1
Mass of fat in mixture is;
She purchases 5 pounds of ground beef which is 15% fat
F1 = 15% of 5 pounds = 0.15×5 pounds
F1 = 0.75 pound
and combines it with 7 pounds of ground turkey which is only 3% fat
F2 = 3% of 7 pounds = 0.03 × 7
F2 = 0.21 pound
Total mass F = F1 + F2
F = 0.75+0.21
F = 0.96 pound
Total mass of mixture T = 5 + 7 pounds
T = 12 pounds.
From equation 1,
%P = F/T × 100%
%P = 0.96/12 × 100%
%P = 0.08×100%
%P = 8%
the percentage of fat in the mixture is 8%
