Answer: 25% of 40 or 0.25 of 40 is 10.
Step-by-step explanation:
Basically you have to divide 40 by 10 because 1/4 of 100 is 25. 25 is 1/4 of 100.
So knowing this 40/0.25 is equal to 10. This is why 0.25 of 40 is 10.
Answer:
reflection over the x-axis
shifted 3 right
shifted 2 up
Step-by-step explanation:
This function is quadratic. Quadratic graphs are written as y=a(x-h)^2+k. Where a is a non-zero number that affects the vertical appearance of the graph, h is the horizontal placement, and k is the vertical placement.
When a is negative then, the graph has been reflected over the x-axis. This makes it look like it has been turned upside down. The variable h affects how the x-values are shifted. In this equation, h looks negative but it is actually positive because if you look at the formula, h is being subtracted. Positive h values move the graph right. So, the graph is shifted 3 units to the right. Finally, k does the same thing as h but on the vertical (y) axis. So, +2 makes the graph shift 2 units up.
The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Step-by-step explanation:
The given is,
Roberto score on math quiz at last week is 74
This week he made an 85 on the quiz
Step:1
Formula to calculate the percentage of increase the score,
× 100...........(1)
From the given,
Final score = 85
Starting score = 74
Equation (1) becomes,
× 100
= 
× 100
= 0.1486486 × 100
= 14.86486 %
≅ 14.87 %
Percentage of increase = 14.87 %
Result:
The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Wheres the graph
???i don’t see no graph to answer
Let's write equations for both Monica and Michael to represent what they should have.
Let's have W represent the number of weeks that pass.
So Monica already has $25 and wants to save $5 each week, her equation will be:
Monica = 25 + 5W
Michael has $16 and will save $8 each week, so his equation is:
Michael = 16 + 8W
We want to know the number of weeks where Monica and Michael have the same amount of money, so:
Monica = Michael or 25 + 5W = 16 + 8W
Solve for W:
1. subtract 16 from both sides to get 9 + 5W = 8W
2. subtract 5W from both sides to get 9 = 3W
3. divide both sides by 3 to get W = 3
So it takes 3 weeks for them to have saved the same amount of money. Plug W = 3 back into one of the equations (it doesn't matter which one) to figure out how much they saved.
16 + 8W = 16 + 8*(3) = $40
