The Republicans won the most electoral votes in the election.

Interpreting the presidential election using the map description

From the question, we have the following parameters that can be used in our computation:

Description by county:

Land areas won by Republicans is greater than those won by Democrats.

Description by state:

Democrat winner = approximately half

Republican winner = approximately half

The above means that

The republican won the election

This is because;

When calculated by states, they have the same proportionWhen calculated by county, Republican hold more votes

Hence. The Republicans won the most electoral votes in the election.

A salesperson uses a circle graph to represent shoe sales for one year. The central angle for the portion of the graph that represents running shoes measures 80°. If 200 running shoes were sold, how many shoes were sold?

Thanks! :)

Answers

Answer:

900. Give Braylist

Step-by-step explanation:

I'm right

To solve the problem, we can use proportions. Since the central angle for running shoes is 80 degrees, we know that the ratio of running shoes sold to total shoes sold is 80/360. This is because the total number of degrees in a circle is 360. Therefore, we can set up the proportion:

80/360 = 200/x

where x is the total number of shoes sold. Solving for x, we get:

x = (360 * 200)/80

x = 900

Therefore, the total number of shoes sold is 900.

Answer:

105 square inches

Step-by-step explanation:

area of a triangle = 1/2( base * height)

The base is 5 and the height is 8.

= 1/2 ( 5 *8)

= 1/2(40)

= 20

The area of each triangle = 20 sq inches

So 4 triangles x 20 sq inches each = 80 sq inches.

The area of the square is 5 x 5 = 25 sq inches.

Add them together.

80 + 25 = 105 square inches

Answers

Answer:

13/35

Step-by-step explanation:

Probability determines the likelihood of an event happening.

Since we are not looking at the 7th Graders list, let's focus on the list on 8th Graders.

Given:

8th grade

Guitar - 4 students

Bass - 13 students

Drums - 13 students

Keyboard - 5 students

Since we are trying to find the probability of an eighth grader chosen at random to play the drums, let's turn our attention to how many students actually play the drums.

13 students play the drums.

In order to find the probability of a student chosen at random who plays the drums, we have to find how many students play the drums (which we already found) out of the total amount of students there are in that grade/section. Summing up, probability = the amount of favorable cases divided by the amount of possible cases.

Let's use this formula:

P(A) = n/N

Where "P(A)" stands for the probability of the event "A". And "n" represents the # of favorable outcomes and "N" represents the # of total possible outcomes.

Let's find how many students are in 8th grade now by adding all the people who play the musical instruments together:

4 + 13 + 13 + 5

= 35 possible outcomes.

Now let's plug it into the formula:

P(A) = n/N

P(A) = 13/35

13/35 can simplify any further.

The probability of choosing a student who plays the drums at random is 13/35.

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit."

Answers

The following exercises try to calculate the variation rate of a quantity when the variation rate of another quantity related to it is known. In this type of exercise, the "variation rate" is interpreted as a derivative and, in most cases, it is enough to use the chain rule to obtain what is requested. You have to choose the units according to the data of the problem; For example, if a volume is measured in liters, we will have to measure lengths with decimeters.
Exercise 1. How fast does the level of the water contained in a cylindrical tank drop if we are emptying it at a rate of 3000 liters per minute?
Solution
Let r be the radius of the cylinder and h be the height measured in decimeters. Let V(t) be the volume of water, measured in liters (=dcm3), that is in the cylinder at time t measured in minutes. The information they give us is a variation rate
V(t + 1) − V(t) = −3000 liters per minute
In this type of exercise, the variation rate is interpreted as a derivative: V ′(t) = −3000. Notice that V(t + to) − V(to) u V′(to)t, so the interpretation is reasonable. The negative sign of the derivative is required since the volume decreases with time. Since the radius is constant but the height of the water depends on time, we have
and we deduce therefore
V(t) = πr2h(t)
V′(t) = −3000 = πr2h′(t)
h′(t) = −3000 decimeters per minute πr2
If we express the measurements in meters, then h ′ (t) = − 3 meters per minute. πr2
Exercise 2. A point P moves on the part of the parabola x = y 2 situated in the first quadrant in such a way that its x coordinate is increasing at a rate of 5 cm/sg. Find the speed at which point P recedes from the origin when x = 9.
Miguel Martín and Javier Pérez (University of Granada)

Solved exercises chapter 2 2 Solution
Let (x(t), y(t)) be the coordinates, measured in centimeters, of the point P at the instant t measured in seconds. They tell us that y(t) > 0 and that x(t) = y(t)2. The distance from point P to the origin is given by f (t) = px(t)2 + y(t)2 , so
′ x(t)x ′(t) + y(t)y ′(t) f (t) = px(t)2 + y(t)2
What we are asked for is f ′(to) knowing that x(to) = 9. In this case it must be y(to) = 3. We also know x′(t) = 5 (cm/sg). With this it is easy to deduce the value of y′(to) = x′(to) = 5. Finally,
2y(to) 6
′ x(to)x′(to)+y(to)y′(to) 45+3(5/6) 95
