Annie has a lemonade stand and her mom pays her 5 dollars every week for her to go get her supplies. Her dad pays her ten dollars one week. She has 35 dollars that month. How many weeks did Annie’s mom pay her?
35 - 10 = 25
25 divided by 5 equals 5.
To check: 5 x 5 equals 25 plus 10 equals 35
Answer:
he would have used about 87 bands for each ball so if you round to the nearest ten yes it is reasonable to say he used 90 bands per ball
Answer:
D
Step-by-step explanation:
The area (A) of a kite is calculated as
A = 
× d₁ × d₂ ( d₁ and d₂ are the diagonals )
This can be represented as
Multiply the diagonals then divide by 2 → D
A.) To find the maximum height, we can take the derivative of h(t). This will give us the rate at which the horse jumps (velocity) at time t.
h'(t) = -32t + 16
When the horse reaches its maximum height, its position on h(t) will be at the top of the parabola. The slope at this point will be zero because the line tangent to the peak of a parabola is a horizontal line. By setting h'(t) equal to 0, we can find the critical numbers which will be the maximum and minimum t values.
-32t + 16 = 0
-32t = -16
t = 0.5 seconds
b.) To find out if the horse can clear a fence that is 3.5 feet tall, we can plug 0.5 in for t in h(t) and solve for the maximum height.
h(0.5) = -16(0.5)^2 + 16(-0.5) = 4 feet
If 4 is the maximum height the horse can jump, then yes, it can clear a 3.5 foot tall fence.
c.) We know that the horse is in the air whenever h(t) is greater than 0.
-16t^2 + 16t = 0
-16t(t-1)=0
t = 0 and 1
So if the horse is on the ground at t = 0 and t = 1, then we know it was in the air for 1 second.
