Answer:
The value of p = -14
Step-by-step explanation:
Given the equation
Divide both sides by -6
simplify
Subtract 8 from both sides
simplify
Therefore,
The value of p = -14
Answer: red is 13.36
Blue is 93.625
Step-by-step explanation:
Let the red marbles be y
Based on the question,red is 4times which means 4y
And blue is 7times greater than red which means 7(4y)
Blue + red=107
7(4y) + 4y=107
28y+4y=107
32y=107
Divide both sides by 32
Y=3.34
Red =4y
Red= 4(3.34)
Red =13.36
Blue= 7(4y)
Blue=7(4×3.34)
Blue= 93.625
Answer:
77.2 milliroentgens per hour
Step-by-step explanation:
The first step is to find the constant of proportionality
I ∝ 1/d²
I = k/d²
62.5 = k/(3)²
k = 562.5
The second step is to calculate the intensity at 2.7 meters:
I = 562.5/d²
I = 562.5/(2.7)²
I = 77.2 milliroentgens per hour
No she is not correct, because the absolute value of a number is its distance from zero on a number line. Therefore, you would take a number, say -1. The absolute value of this number is 1. So, add 1 and you would get 2. If I'm correct, 2 is not equal to zero. I hope this helps you out! ;)
