Answer:
$14.90625
Step-by-step explanation:
Using the conversion rate
$1 = 0.8 pounds
If you buy 2.6 pounds of apples and 1.475 pounds of peaches, the total cost of apple and peaches is expressed as:
= 2.6 pounds + 1.475 pounds
= 4.075 pounds
Convert to dollars
$1 = 0.8 pounds
$x = 4.075 pounds
cross multiply
0.8x = 4.075
x = 4.075/0.8
x = $5.09375
This means that the cost of the apple and peaches is $5.09375.
If you hand the cashier a $20 bill, the change that you will receive will be: $20 - $5.09375 = $14.90625
Answer:
7.50h = 205
divide both sides of equation by 7.5
h = 27.33 hours
If you round that number it will take about 27 hours to make $205

Hello from MrBillDoesMath!
Answer:
y^2-5y -4
Discussion:
The problem asks us to find the polynomial, g(y), such that
y^2-5y + 1 - g(y) = 5 => (add g(y) to both sides)
y^2 -5y + 1 - g(y) + g(y) = 5 + g(y) =>
y^2 -5y + 1 + 0 = 5 + g(y) => (as -g(y) + g(y) = 0)
Finally subtract 5 from both sides:
y^2 - 5y + 1 -5 = (5 -5 ) + g(y) =>
y^2-5y -4 = g(y)
Thank you,
MrB
You can draw a diagram of the situation, representing it by a right triuangle.
In the right triangle the hypotenuse is the distance indicated by the radio signal, 1503 m, and the angle is 41°.
The opposed leg to 41° is the height of the ballon.
Then you can use the sine trigonometric function.
sine (41°) = opposed leg / hypotenuse = x / 1503 m => x = 1503m * sine(41°)
=> x = 986m.
Answer: 986m
