find the area of the shape below
it is year 7 work can someone help i'll give em 50points for it
Answers
The area is 198.5cm sq
The shape can be divided into a circle of
5cm radius
as diameter is 10cm
radius = d/2
and a rectangle of 12×10 cm dimensions
length is 22-( 2×5) 12cm
and breadth is 10cm
The area of the circle is pi(r square)
which is 3.14×25
= 78.5 cm sq
The area of the rectangle is l×b
which is 12×10
= 120 cm sq
The total area is thus
area of rectangle plus area of circle
which is 198.5cm sq

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

Order the numbers from closest to zero to farthest from zero:
4.38, l4.5l, l-4.6l, -l4.9l
HELPPPPP
Answers
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." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
With that being said, here is the order of the numbers from smallest to largest:
4.38
4.5
4.6
4.9
Answer:

Xin recorded the grade-level and instrument of everyone in the middle school School of Rock below.
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 gradeGuitar - 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.

Answers
Answer:
900. Give Braylist
Step-by-step explanation:
I'm right
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.

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
f (to)= px(to)2+y(to)2 = 81+9 =6√10 cm/s sorry is a lot

What is the value of x?
The value of x is calculated as follows;The sum of the interior angles of a polygon with n sides is given by the formula;(n-2) x 180
Since the regular polygon in question can be decomposed into 46 triangles, it has 46 x 3 = 138 sides.The value of each interior angle is calculated as;= (n - 2) x 180 / n = (138 - 2) x 180 / 138 = 169.6⁰9.5x + 26.2 = 169.69.5x = 143.4x = 15.1

Answer:
The answer is The Democrats won the most electoral votes in the election.
The map showing the results by county shows that the Republicans won more land area, but the map showing the results by state shows that the Democrats won more states. The electoral college is made up of electors from each state, and the number of electors each state has is equal to the number of seats it has in Congress plus its two senators. The Democrats won more states in 2008, so they won more electoral votes and the election.
