You want to determine your speed running across the room. What is one piece of data you need?
A) The distance you run
B) When you start your stopwatch
C) How big each step is
D) How fast you are moving
I know its not C)
Answer:
D) How fast you are moving
Step-by-step explanation:
Well, if you're talking about speed, then we don't want distance yet, do we? If you were talking about how far someone ran, then distance would be a piece of data. But speed is "how fast", so something tells me the answer is D.

if y varies inversely as x and y=16 when x=4, find y when x=3
Answer:
21.33 to nearest hundredth
Step-by-step explanation:
Inverse Variation is y = k / x where k is a constant.
Plug in the given values to find k:-
16 = k/4
k = 4*16 = 64 so the equation of variation is y = 64/x.
So when x = 3, y = 64/3 = = 21.33 to nearest hundredth.
The value of y when x = 3 is 21.33
The value of y = 21.33
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
The value of x = 4
The value of y = 16
Now , the value of y is inversely proportional to x
So ,
y ∝ 1/x
y = k/x
where k is the constant of proportionality
So , k = yx
Now , substituting the value of x and y in the equation , we get
k = 16 x 4
k = 64
So , when the value of x = 3 ,
y = k / x
y = 64 / 3
y = 21.33
Hence , The value of y when x = 3 is 21.33

One number is 7 more than another.The difference between their squares is 217.What are the numbers?
The problem where one number is 7 more than another and their squares differ by 217 can be solved by creating a system of equations and simplifying to find the numbers are 12 and 19.
Explanation:To solve the problem where one number is 7 more than another and the difference between their squares is 217, we can create a system of equations. Let's assume the first number is x and the second number is x+7. The problem then translates to the equation (x+7)² - x² = 217.
Step-by-step solution:
Expand the left side of the equation: (x+7)² - x² = (x² + 14x + 49) - x².Cancel out the x² terms: 14x + 49 = 217.Subtract 49 from both sides: 14x = 168.Divide both sides by 14: x = 12.Therefore, the first number is 12 and the second number is 12 + 7 = 19.After computing the solution, we find that the two numbers are 12 and 19.

marco wants to invest his savings in a bank for 3 years. he has £15000 to invest and recieves offers from two banks: bank of peace= 2.5% a year compound interest or bank of trust= 3.8% for 1st year 1% extra for each extra year. which bank should marco choose to get the most interest over the three year period? you must show all your working
Bank of Peace= 15000(1+0.025)³=£16153.36
Bank of Trust=15000(1+0.038)=£15570
£15570(1+0.01)=£15882.95
Bank of Peace is the best choice.
I would choose the Bank of Peace to get the most of my savings.
Formula for calculating the compound value of the savings at the Bank of Peace = FV = P (1 + r)^n
FV = Future value
P = amount deposited
R = interest rate
N = number of years
£15,000 x (1.025)^3 = £16,153.36
Interest earned at the Bank of Trust in the first year = £15,000 x 0.038 = $570
Total amount at the end of the first year = $570 + £15,000 = £15,570.
Value for the two extra years = $15,570 x (1.01)^2 =$15,882.96

If a pizza is cut into six equal pieces. And then it’s cut in half to create two smaller equal pieces. What fraction of the total pizza does one of the smaller pieces represent?
Answer:
1/12
Step-by-step explanation:
Since the pizza was cut into 6, each of the slices = 1/6.
But because the pizza was then cut into half, it makes each slice = 1/12
6 x 2 = 12
Therefore the answer is 1/12.

The correct answer is:
7/10
Explanation:
Finding the totals of each column and row, we find:
There are 3+2+1 = 6 children in the baseball league.
There are 7+2+1 = 10 children in the softball league.
There are 3+7 = 10 children in the 7-9 division.
There are 2+2 = 4 children in the 10-12 division.
There are 1+1 = 2 children in the 13-15 division.
There are a total of 10+6 = 16 children.
We start with the information that the team is a member of the softball league. There are 10 children in this league; this is the denominator of the probability.
There are 7 children in the 7-9 division that are in the softball league. This gives us the probability 7/10.

jim and Jon are painting a fence. Jon painted 1/4 of the fence. Jim painted 5/12 of the fence. how much of the fence did they paint in total?
Our first step is the find the lcm of 4 and 12 so we can add the two fractions without having a problem.
The lcm of 4 and 12 is clearly 12 because 12 is a multiple of 4. 12 divided by 4 is 3, so you must multiply by 3/3 to be able to add the two fractions.
1/4*(3/3)=3/12.
So, 3/12+5/12=7/12.
Jim and Jon painted 7/12 of the the fence.
Answer:
2/3 of the fence
Step-by-step explanation:
Jim painted 1/4 of the fence
Jon painted 5/12 of the fence
Together they painted
1/4+5/12 of the fence
We need a common denominator to add the fractions
The common denominator is 12
1/4*3/3 + 5/12
3/12 + 5/12
8/12
This can be simplified by dividing the top and bottom by 4
2/3
Together, they painted 2/3 of the fence.

Answer:
$8.2
Step-by-step explanation:
The final price of the coat = $45 -0.2 * $45 = $36

What is the unit rate for $12.50 for 5 ounces?
Answer:
The correct answer is $2,50.
Step-by-step explanation:
The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.
We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.
To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:
12.50 / 5 = 2.50
In this way we can verify that the unit price of 5 ounces is $ 2.50
The correct answer is $2,50, is the unit rate for $12.50 for 5 ounces.
Here, we have,

Step-by-step explanation:
the equation of a parabola in vertex form is
y = a (x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
to obtain this form use the method of completing the square
• add/subtract (half the coefficient of the x-term)² to x² + 2x
= x² + 2(1)x + 1 - 1 + 5
= (x + 1)² + 4 ← the second option
Catalina uses a 3 1/2 ounce packet of seasoning for her steaks. The packet contains of 1 1/3 ounces of garlic powder and 1 1/4 ounces of onion powder. The remainder of the packet consists of black pepper. How many ounces of black pepper are in the packet of seasoning?
Answer:
11/12
Step-by-step explanation:you have to turn all the mixed numbers into improper fraction so 1 1/3 is 16/12 1 1/4 is 15/12 and if you add them you get 2 7/12 and that minus 3 6/12 is 11/12
There are 11/12 ounces of black pepper in Catalina's seasoning packet.
Catalina uses a 3 1/2 ounce packet of seasoning for her steaks.
This packet contains 1 1/3 ounces of garlic powder and 1 1/4 ounces of onion powder.
To find out how many ounces of black pepper are in the packet, we need to subtract the combined weight of the garlic and onion powders from the total weight of the seasoning packet.
Garlic powder: 1 1/3 ounces = 4/3 ounces
Onion powder: 1 1/4 ounces = 5/4 ounces
Total seasoning packet: 3 1/2 ounces = 7/2 ounces
We then add the amounts of garlic and onion powders to get their combined weight:
4/3 + 5/4 = (16 + 15) / 12 = 31/12 ounces
The next step is to subtract the combined weight of the garlic and onion powder from the total weight of the seasoning packet:
7/2 ounces - 31/12 ounces = (7\*6 - 31) / 12 = (42 - 31) / 12 = 11/12 ounces.
