Answer:
Sara's speed was 6.4 meters per second faster
Step-by-step explanation:
(Were going to name the olympian steve)
First, we have to find how many meters per second Steve ran. To find this we must divide the number of meters he ran by the amount of time it took him to run all 100 meters.
100 ÷ 9.6 =10.41666667
Since the problem tells us to round to the nearest tenth of a second we round 10.41666667 to 10.4. So now we know how many meters per second Steve ran. Now all we have to do is subtract the number of meters per second Sarah ran, from the number of meters per second Steve ran.
Sarah- 16.8 meters per second
Steve- 10.4 meters per second
16.8-10.4= 6.4
And there you have it! Sarah ran 6.4 meters per second more than Steve. I hope this answer was accurate and helpful. I hope you have an AMAZING day!

Answer:
[tex] - 7.375[/tex]
Step-by-step explanation:
43/4=10.75
21/8=2.625
6-10.75= -4.75
-4.75-2.625= -7.375
36 divided by 6+(18-6x2)
Answer:
12.
Step-by-step explanation:
This equation seems to want you to use the Order of Operations, a.k.a PEMDAS (which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). When you do a problem like this, you use the Order of Operations to figure out the order in which you'd solve your problem.
You would first solve what is in parentheses, since that is the first letter in PEMDAS. 18-6x2 is what we have in our parentheses, but it's too confusing to be solved yet. The next letter is E, a.k.a exponents, but there are no exponents in this equation, so we move on. Next is M, Multiplication. We would multiply 6 by 2, which gives us 12. Moving on, we have D, Division. We would do 36/6, which is 6.
Our 5th letter is A, Addition. We would have to add our 6 to (18-12), but that couldn't work, since our 18-12 is still in parentheses, and those come first. So, we would skip to the last letter, S, Subtraction. 18-12=6, and since we solved all the problems in the parentheses, we remove them, and add both 6's together, giving us 12.
Jason bought 6 movie tickets and four bags of popcorn Michael bought two movie tickets and three bags of popcorn each bag of popcorn was $5 and they spent $131 total. write an equation to solve.
Answer:
Equation is [tex]8M + 7P = 131[/tex]
[tex]M = \$12[/tex]
Step-by-step explanation:
Given
Jason: 6 Movies and 4 popcorn
Michael: 2 Movies and 3 Popcorn
1 Popcorn = $5
Total = $131
Required
- Write an equation to solve
Represent Movie with M and Popcorn with P
For Jason, we have:
6M + 4P
For Michael, we have:
2M + 3P
Add these parameters together
Jason + Michael = $131
[tex]6M + 4P + 2M + 3P = 131[/tex]
Collect Like Terms
[tex]6M + 2M+ 4P + 3P = 131[/tex]
[tex]8M + 7P = 131[/tex]
Hence the equation is [tex]8M + 7P = 131[/tex]
From the question, we have that
[tex]P = \$5[/tex]
Substitute 5 for P
[tex]8M + 7 * 5 = 131[/tex]
[tex]8M + 35 = 131[/tex]
Solve for M
[tex]8M = 131 -35[/tex]
[tex]8M = 96[/tex]
[tex]M = \frac{96}{8}[/tex]
[tex]M = \$12[/tex]

No, the piecewise graph is NOT a function because it does NOT pass the vertical line test.
The vertical line test is where we try to pass a line through more than one point on the curve. If it is not possible to do this, then the graph is said to "pass the vertical line test".
In this case, the given graph fails the vertical line test. Look at something like x = -2. We can draw a vertical line through here to pass through more than one point. One point is on the upside-down V shape, and the other point is on the parabolic shape. Plugging x = -2 into this leads to more than one y outputs.
A function is only possible if any valid x input (from the domain) leads to exactly one output y value (in the range).

if 4% of packages get lost in the mall, then which DECIMAL best represents the amount of packages lost in the mall?
Answer:
0.04
Step-by-step explanation:
We know that 4% of packages are lost in the mail, but we want to know the decimal.
We must convert 4% to a decimal. There are 2 ways to do this.
1.
Remove percent sign and divide by 100.
4%
4
4/100
0.04
2.
Remove percent sign and move decimal place two spots to the left.
4%
4 = 4.0
4.0 --> 0.4 --> 0.04
0.04 of the packages are lost in the mail.

5(-2x-4)-2x+2=-425(−2x−4)−2x+2=−42
Answer: x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(−2x−4)−2x+2=−42
(5)(−2x)+(5)(−4)+−2x+2=−42(Distribute)
−10x+−20+−2x+2=−42
(−10x+−2x)+(−20+2)=−42(Combine Like Terms)
−12x+−18=−42
−12x−18=−42
Step 2: Add 18 to both sides.
−12x−18+18=−42+18
−12x=−24
Step 3: Divide both sides by -12.
-12x/-12=-24/-12

Raina has a fabric of area 7912 centimetre square find the largest square that can be cut from it how much piece will be left in any
Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Raina has a fabric of area 7912 centimetre square find the largest square that can be cut from it how much piece will be left
Area of fabric = 7912 cm²
Largest square that can be cut from it :
Taking the square root of 7912
Sqrt(7912) = 88.94 cm
Hence, it can be deduced that the largest square tht can be cut from it will be 88cm
From area of a square = a²
Where area is the length of the side (since all sides are equal)
a² = 88² = 7744cm²
Hence, area left = (7912 - 7744) cm² = 168 cm²
The null space for the matrix is span{A,B} where:_____.
Answer:

What is the average rate of change over the interval [0, 4]?
Answer:
[tex] \frac{3}{4} [/tex]
Step-by-step explanation:
Given:
Interval, [0, 4]
Required:
Average range of change over [0, 4]
SOLUTION:
Find f(0) and f(4) from the graph:
[tex] f(0) = 0 [/tex] (when x = 0, y = 0)
[tex] f(4) = 3 [/tex] (when x = 4, y = 3)
Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]
Where,
[tex] a = 0, f(a) = 0 [/tex]
[tex] b = 4, f(b) = 3 [/tex]
Plug in the values into the formula for average rate of change.
[tex] = \frac{3 - 0}{4 - 0} [/tex]
[tex] = \frac{3}{4} [/tex]
Average rate of change [tex] = \frac{3}{4} [/tex]

jar contains pink and green marbles in the ratio 3 : 4. When John replaces 5 of the green marbles with 8 pink marbles, the ratio becomes 29 : 23. The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is : .
Answer:
52:49
Step-by-step explanation:
pink:green
The ratio of pink to green marbles is
3k:4k
He removes 5 green marbles and adds 8 pink marbles.
Now the ratio of pink to green marbles is
(3k + 8):(4k - 5)
This rario is equal to 29:23.
(3k + 8)/(4k - 5) = 29/23
29(4k - 5) = 23(3k + 8)
116k - 145 = 69k + 184
47k = 329
k = 7
Original amounts:
3 * k = 3 * 7 = 21 pink
4 * k = 4 * 7 = 28 green
Original total = 21 + 28 = 49
Amounts after replacement:
3k + 8 = 3(7) + 8 = 29 pink
4k - 5 = 4(7) - 5 = 23 green
Total after replacement = 23 + 29 = 52
Answer: The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is 52:49.
