Answer:

20%

Step-by-step explanation:

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%

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

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.

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:

slope = [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

Slope-intercept form is the way in which an equation is written to easily identify the line's slope and y-intercept. It is represented by the equation y = mx + b, in which m represents the slope.

By looking at the equation, we can see that it takes the y = mx + b format - y is isolated - therefore it is in slope-intercept form. Remember that the number in place of the m would represent the slope - and in this case, that number is [tex]\frac{5}{8}[/tex].

Final Answer:

[tex]\sf{Slope = \dfrac{5}{8}}\\\sf{Y-intercept: -\dfrac{1}{2}}[/tex]

In-depth explanation:

The question is asking us to find the slope of the line, whose equation is;

[tex]\leadsto\quad\bf{y=\dfrac{5}{8}x-\dfrac{1}{2}}[/tex]

The format of this equation is: [tex]\boldsymbol{\sf{y=mx+b}}[/tex]. This is known as slope-intercept; it's the most common way of writing the equation of a line.

In y = mx + b, the variable "m" denotes the slope, or the rate of change, of a line; b denotes the y-intercept, or the point where the line intercepts the y-axis.

Also, the slope is the number before x, while b is the constant term.

Similarly, the slope is 5/8 and the y-intercept is -1/2.

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.

Step-by-step explanation:

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.

150-30=5x

Step-by-step explanation:

If the total is $150 and a pair of jeans is $30, then you'd subtract them. Since you have to find out how much each shirt is, you'd put 5x on the other side of the equal sign. Then solve for X.

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

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.
