Danielle is making protein balls. She uses 1 1/2 cups of protein powder, 2 1/4 cups of peanut butter, and 2/3 cup of honey. Which equation represents the total number of cups of ingredients Danielle uses?
Answers
Answer:
4 (5/12). four and five-twelfths
Step-by-step explanation:
1/2 is the same as 2/4, so: 1 1/2 = 1 2/4
1 2/4 + 2 1/4 = 3 3/4
3/4 and 2/3 have a LCM or least common multiple of 12
4 x 3 = 12 and 3 x 4 =12; but whatever you do to the bottom you have to do to the top (3/4) turns into (9/12) and (2/3) turns into (8/12)
9/12 + 8/12 = 17/12 or 1 5/12 as a mixed number
3 + 1 5/12 = 4 5/12

Help! Giving brainliest and 10+ points, A ball is dropped from the top of a 400-ft tall tower. The relationship between the time, t, in seconds, and the height, h(t), in feet, of the ball can be modeled by a quadratic function. Specific values of the function are shown in the table below
Part A: Determine the average rate of change of h(t) between t = 2 and t = 5.
Part B:Explain what this average rate of change means in terms of the context.
Answers
The average rate of change of h(t) between t = 2 and t = 5 is -112. See the explanation below.
What does this average rate of change means in terms of the context?Because the average rate of change is negative it simply means that the slope of the Quadratic function is also negative.
What is the calculation showing the above answer in part A?We are given the following:
When t =2; h(2) = 336
When t = 5; h(5) = 0
Recall that the Average Rate of Change on the interval [a,b] is given as:
[ta - tb]/(b-a)
Since the state interval is [2,5]; and
h(2) = 336; and
h(5) = 0
Hence
ARC = 0-336/5-2
= -336/3
= -112

D. (x, y) + (x + 1, y - 4)
Answers
Answer:
D
Step-by-step explanation:
So when looking at this problem, its important to note that your X is your horizontal axis, and your Y is your vertical axis. So when moving left or right, you want to look at the x, so generally adding to X moves the point to the right, and subtracting from x moves the graph to the left. So for X, because you are looking at moving 1 unit to the right, you are going to want to add 1 (x+1), Then since y is your vertical axis, this will be your up or down factor. So its very similar if you are adding to y, you are moving up, but if you are subtracting from y, you are moving down. Therefore your final answer will be (x+1, y-4)

Answer:200
Step-by-step explanation:
Answer:
No, differentStep-by-step explanation:
Last yearBought 40 sets
Sold 25 sets
Error = 25 - 40 = -15Absolute error = | - 15| = 15Percent error = 15/40*100% = 37.5%This yearBought 75 sets
Sold 60 sets
Error = 60 - 75 = -15Absolute error = |-15| = 15Percent error = 15/75*100% = 20%We can see absolute errors are same but percent errors are different.
The reason is the referenced numbers are different.

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:
x = 1 and y = 4
Step-by-step explanation:
Multiply the top equation by 7 on both sides, and then cancel it out:
7(5x + y) = 7(9)
35x + 7y = 63
Now use this equation to cancel out -7y on the second equation:
35x + 7y = 63
10x - 7y = -18
45x = 45
x = 1
Now that we have our x-value, we can plug it into one of our two original equations:
5(1) + y = 9
y = 4
