Answer:
Parker is NOT right when he says that it is a division problem 6 ÷ 3.
In fact, it is a multiplication problem 6 × 3 because 6 × 3 = 18 would give us the correct number of total rectangles which are 18
Step-by-step explanation:
Total number of rectangles = 18
As there are 3 rows with each row containing 6 rectangles.
Now, if we multiply 6 with 3, we get the result 18.
Thus,
6 × 3 = 18
Hence, Parker must have mentioned that this arrow of 18 rectangles shows the multiplication problem 6 × 3.
Thus,
Parker is NOT right when he says that it is a division problem 6 ÷ 3.
In fact, it is a multiplication problem 6 × 3 as 6 × 3 = 18 would give us the correct number of total rectangles which are 18.

b) Work out the new value of G
give your answer in standard form correct to 3 significant figures
Answer:
a. G = 4590.0
b. G = 4550.0
Step-by-step explanation:
Given that: G = [tex]\sqrt{\frac{m}{t^{2} } }[/tex]
a. m = 6.1 x [tex]10^{-5}[/tex] and t = 1.7 x [tex]10^{-6}[/tex]
Thus,
G = [tex]\sqrt{\frac{6.1*10^{-5} }{(1.7*10^{-6}) ^{2} } }[/tex]
= [tex]\sqrt{\frac{6.1*10^{-5}}{2.89*10^{-12} } }[/tex]
= [tex]\sqrt{21107266.44}[/tex]
G = 4594.26452
G = 4590.0
b. m = 6.1 x [tex]10^{-5}[/tex] + ( 6.1 x [tex]10^{-5}[/tex] x 0.08)
= 6.588 x [tex]10^{-5}[/tex]
t = 1.7 x [tex]10^{-6}[/tex] + (1.7 x [tex]10^{-6}[/tex] x 0.05)
= 1.785 x [tex]10^{-6}[/tex]
So that,
G = [tex]\sqrt{\frac{6.588*10^{-5} }{(1.785*10^{-6}) ^{2} } }[/tex]
= [tex]\sqrt{\frac{6.588*10^{-5} }{3.186*10^{-12} } }[/tex]
= [tex]\sqrt{20676505.9}[/tex]
G = 4547.1426
G = 4550.0

Answer:
D. John's boat was farther and faster
Step-by-step explanation:
The equation tells you that at x = 0, Roberta's boat was 10 miles from the dock. The words tell you John's boat started 20 miles from the dock, so his boat started farther away.
John's boat traveled a distance of (55 -20) = 35 miles in 5 hours, so the speed was (35 mi)/(5 h) = 7 mi/h. The equation tells you Roberta's boat traveled 6 miles for each hour, so John's boat was faster.
John's boat was farther and traveled more quickly
__
Additional comment
The variables in Roberta's equation are not defined. In order for the problem to make sense, we must assume that x represents time in hours, and y represents distance in miles.

The graph represents the amount of money Sal earns for babysitting.
Graph where the x- axis gives time in hours and runs from zero to three and beyond. The y- axis gives earnings in dollars and runs from zero to twenty four and beyond. A straight line intersects the axes at (0, 0). Its coordinates are (5, 4), (1, 8), (1.5, 12), (2, 16), and (2.5, 20)
Part A
What does the ordered pair (2.5, 20) represent in the situation?
A. $2.50 for 20 hours
B. $1 for 0.125 hours
C. $0.125 for 1 hour
D. $20 for 2.5 hours
Part B
Does the graph represent a proportional relationship? Explain.
A.
Yes. The line passes through the origin.
B.
Yes. The line has a variable rate of change.
C.
No. The slope is not constant.
D.
No. The line has a y-intercept greater than 0.
Part C
What is the linear equation represented by the graph?
A. y = 20x + 2.5
B. y = 2.5x + 20
C. y = 8x
D. y = 0.125x
Answer: d, a, and c
Step-by-step explanation:
Part(A)
The ordered pair (2.5, 20) represents $2.50 for 20 hours. the correct option is A.
Part(B),
Yes. the line passes through the origin. The correct option is A.
Part(C),
The linear equation represented by the graph is y = 8x. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that coordinates are (0.5, 4), (1, 8), (1.5, 12), (2, 16), and (2.5, 20).
Part(A),
The ordered pair (2.5,20) represents that the earning is $20 for the work of 2.5 hours.
Part(B),
The slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 8 - 4 ) / ( 1 - 0.5 )
Slope = 4 / 0.5
Slope = 40 / 5
Slope = 8 hours
The y-intercept is calculated as,
y = mx + c
16 = ( 2 x 8 ) + c
c = 16 - 16
c = 0
Hence, the line passes through the origin.
Part(C),
The equation of the line will be written as,
y = mx + c
y = 8x + 0
y = 8x

7. If 294 J of heat is transferred to a 10.0 g sample of silver at 25 ºC, what is the
final temperature of the silver? Specific heat capacity of silver is 0.235 J/gºC.
Answer:
T~final is 150.11 C
Step-by-step explanation:
To solve this we need this specific heat equation:
Q=mc(T~final - T~initial) that is the difference of final temperature minus initial temperature.
We are given:
Q = 294 J
m = 10 g
c = 0.235 J/gC
T~initial = 25 C
Plug the values in to the equation
294 J = 10 g * 0.235 J/gC * T(difference)
294 J = 2.35 J/C * T(difference)
Divide both sides by 2.35 J/C
294 J / 2.35 J/C = T(difference)
T(difference) = 125.11 C
If the initial temperature was 25 C then then
T~final = 25 C + 125.11 C or 150.11 C

The area of a triangle is formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. Find A if it is known that parabola opens upwards
Answer:
2/3
Step-by-step explanation:
Answer:
a=2/3
Step-by-step explanation:
1. y=a(x-x1)(x-x2) is a formula for a parabola, x1 and x2 being points where y=0 so in the equation y=a(x-3)(x+2), you know
x1=3, x2=-2
2. Find distance between 3 and -2, which is 5
3. bh/2=A --> 5h/2=10 --> h=4 (h is height)
4. when x=0, y=-6a, y=a(0-3)(0+2)
5. because parabola opens upward, the point of the vertex must be (_, -4)
6. -6a= -4
a=2/3

There is a group of 10 people who are ordering pizza. If each person gets 2 slices and each pizza has 4 slices, how many pizzas should they order?
Answer:
5 pizzas
Step-by-step explanation: If you have 10 people and each will get two slices then you will need 20 pieces of pizza because 10x2 is 20. If each pizza has 4 slices then you will need 5 pizzas because 4/20 is 5.
Answer:
5 pizzas.
Step-by-step explanation:
Find out how many slices the group of 10 people need in total:
2 x 10 = 20 slices
Now, use the total number of slices and divide it with 4 to find how many pizzas they need.
20 ÷ 4 = 5
They need 5 pizzas for 10 people who each get 2 slices.
A polling company plans to create a probability model for a state election. In a telephone survey of 750 residents who stated they were registered to vote, they found that 318 planned to vote for the Democratic candidate, 268 planned to vote for the Republican candidate, with the remainder were undecided. What is a reasonable probability model for the state election?
Select the correct ANSWERS from the list below
54% plan to vote for the Democratic candidate|
22% are undecided.
18% are undecided.
36% plan to vote for the Republican candidate.
46% plan to vote for the Republican candidate.
42% plan to vote for the Democratic candidate
this decides my grade please only answer if you know it
Answer:
22% are undecided
36% plan to vote Republican
42% plan to vote Democratic
Step-by-step explanation:
Take 318 and divide it by 750 to find the democratic vote. Round to the nearest whole number.
318/750 = 0.424
Same for Republican except take 268 and divide by 750.
268/750 = 0.357
Add both percentages together. 36% + 42% = 78%
So there is 22% of the population that either did not answer or are undecided.
The correct answers are:
22% are undecided
36% plan to vote Republican
42% plan to vote Democratic
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Total Resident = 750
Out of which 318 planned to vote for the Democratic candidate, 268 planned to vote for the Republican candidate.
So, 318/750 = 0.424
= 42.4%
and, 268/750 = 0.357
= 35.7%
So, the percentage who decided to vote = 36% + 42% = 78%
Hence, there is 22% of the population that either did not answer or are undecided.

Maria calculate that she could make 18,000 over the summer instead she ended up making 15,000 what is the percentage difference? round your answer to the nearest percent
The formula for Percent difference =
Difference/ Original value × 100
Difference is calculated as:
18000 - 15000 = 3000
Original value = 15000
Hence:
3000/15000 × 100
= 20%
Percent difference = 20%
