Answer:
The team is measuring at 364 ft below the surface
Step-by-step explanation:
Here, we want to get the depth at which the pressure was measured at
to get this, we will have to use the equation that relates the pressure to the depth
From the question, we have this as;
P = 13 + 8/13(d)
From the question, P is 237
Substituting this into the equation, we have
237 = 13 + 8/13(d)
237-13 = 8/13(d)
224 = 8/13(d)
8d = 13 * 224
d = (13 * 224)/8
d = 364 ft
It’s the first one cause C is multiplying by 3 and D is adding by 2
Answer:
The number of hours Jackie worked = 80hours
Step-by-step explanation:
Last summer:
Jackie made $960
Rachel made $960
let number of hours Jackie worked = x
Rachel worked 16 hours more than Jackie:
Number of hours Rachel worked = x + 16
if Jackie earned $y per hour
Rachel earned $2 less per hour = y-2
Jackie: 960 = x × y = xy
Rachel: 960 = (x+16)(y-2)
960 = xy -2x +16y -32
recall xy = 960, insert the value for xy
960 = 960 - 2x +16y -32
- 2x +16y -32 = 0
2x -16y = -32
x-8y = -16
x = 8y-16
recall xy = 960, insert the expression for x
(8y-16)y = 960
8y² -16y = 960
y² -2y - 120 = 0
y²+10y-12y -120 = 0
y(y+10) -12(y+10) = 0
(y-12) = 0 or (y+10) = 0
y = 12 or -10
since y can't be negative, y = 12
x = 8y-16
x = 8(12) -16 = 80
The number of hours Jackie worked = x = 80 hours
Answer:
4 grilled cheese: 9 total lunches
Step-by-step explanation:
Grilled cheese (gc): 200
Total: 200+100+150=<u>450</u>
Ratio: 200 gc: 450 total
SIMPLIFY:
gc: 200/50=4
Total: 450/50=9
ANSWER:
4 gc: 9 Total
So 20 plus g if it makes 25 then we already know that g is 5 because 20 plus 5 makes 25
