Answer:
57 to 63
Step-by-step explanation:
A suitable probability tool can tell you the limits.
8% of scores will be below 56.95 ≈ 57
76% of scores will be above 63.24 ≈ 63
Scores between 57 and 63 will get a D grade.
Answer:
x = 37
Step-by-step explanation:
Vertically opposite angles are equal
Therefore, 2x + 6 = 80
Subtract 6 from both sides: 2x = 74
Divide both sides by 2: x = 37
139.25 in = 11 ft 7.25 in
149 3/16 in= 12 ft 5.2 in
Answer:
1. (4)x + y =50
2x + 4y =172
2. (1)x + y =8
150x + 50y =800
3. (1)x + y =20
25 + 10y =290
Step-by-step explanation:
Just trust me and its too much work explaining and im lazy so just ask your teacher or a friend if you can.
Just set up a proportion with the original numbers and then the numbers you want to find like so: (x1/y1)=(x2/y2) and since you want to find the second y value, just leave y as a variable like so: (15/24)=(3/y) after this just cross multiply and get the answer: 15y=72.....y=4.8
