Find the area of the trapezium.

Answer: $18.49

Step-by-step explanation:

First, add both the tax rate, 4.315 + 4 = 8.315%

Then take 17.07 divided by 100%, then times 8.315% = $1.42

Then add 17.07 + 1.42 = $18.49

The unknown angle in the triangle is as follows:

∠E = 100 degrees.

The sum of angles in a triangle is 180 degrees.

In the diagram, BCD is cut by transversal ACE , AB and perpendicular to BCD and CE ≅ ED.

Therefore,

∠ACB = 180 - 50 - 90 (sum of angles in a triangle)

∠ACB = 180 - 140

∠ACB = 40 degrees

Therefore,

∠ACB ≅ ∠DCE

Hence,

∠DCE = 40 degrees.

Triangle CDE is an isosceles triangle since CE ≅ DE.

Hence,

∠CDE = 40 degrees

∠E = 180 - 40 - 40

∠E = 180 - 80

∠E = 100 degrees.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

The number of 5 on the dice is one.

Probability is the ratio of the number of favorable outcome to the total number of outcome.

The number of faces of dice is 6.

The probability of getting 5 is 1/6.

The even faces on the dice are 2, 4, 6.

The number of even number faces is 3.

The probability of getting even number is 3/6 = 1/2.

The probability of two independent event is the product of the probability of the events.

Therefore, the probability is (1/6) × (1/2)

                                              = 1/12

                                               = 0.083

The solution to the linear equation 3(x + 5) = 1/9 is

x = -4 26/27.

The correct answer is option D; None of these choices are correct.

3(x + 5) = 1/9

open parenthesis

3x + 15 = 1/9

Substract 15 from both sides

3x = 1/9 - 15

3x = (1-135)/ 9

3x = -134/9

divide both sides by 3

x = -134/9 ÷ 3

Multiply by the reciprocal of 3

x = -134/9 × 1/3

= -134/27

x = -4 26/27

Therefore, -4 26/27 is the solution that satisfies the equation 3(x + 5) = 1/9

Using the percentage writing form, we know that Ivan ate 4 pizza slices.

By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage.

The percentage calculation formula is (value/total value)100%.

Add all percentages as numbered values, divide by the total number of sets, and you get the average percentage.

The results by 100.

So, we know that:

Ivan ate 40% of the pizza.

And the pizza was cut into 10 slices.

Rewrite the percentage value as:

4/100 = 0.4

We can calculate how many slices Ivan consumed by multiplying the percentage value by the number of slices:

10 + 0.4 = 4

Hence, Ivan ate 4 slices of pizza.

Therefore, using the percentage writing form, we know that Ivan ate 4 pizza slices.

A pseudovector used in physics to express how quickly an object's angular position or orientation changes over time is called an angular velocity, rotational velocity, or angular frequency vector.

For the smaller pulley, it does 48 rpm (revolutions per minute) each revolution is 360 degrees. This indicates that the pulley completes one revolution every second .

radians / π = degrees / 180  

radians = πx 360 / 180 = 2 π radians per second

The distance covered by both pulleys is equivalent for the larger pulley.

then d1 = d2

every second, small pulley covers a distance of 40π (small pulley circumference) = d1

d2 = 40π = 120π (large pulley circumference) x factor (f)

f = 1/3

a) the revolutions per min by larger pulley=16 rpm

b) the speed of smaller pulley = 3*2π=6π=6rad/sec=360rad/min

c) then speed of the large pulley = 1/3 * 2π = 2/3 π = 0.66 rad/sec=39.6rad/min

d)the speed of smaller pulley=7200 cm/min

Answer:

  1180 cm³

Step-by-step explanation:

You want the volume of a prism with an L-shaped base. It is 20 cm between bases. The outside dimensions of the L are 7 cm high by 11 cm wide; the inside dimensions are 3 cm high by 6 cm wide.

The formula for the volume of a prism is ...

  V = Bh

where B is the area of the base, and h is the distance between them. We know h, but we need to find B.

The area of an L-shape is the area of the rectangle with the outside dimensions, less the area of the rectangle with the inside dimensions.

  A = LW -lw

  A = (11 cm)(7 cm) -(6 cm)(3 cm) = 77 cm² -18 cm² = 59 cm²

Using the above formula, the volume is ...

  V = (59 cm²)(20 cm) = 1180 cm³

The volume of the prism is 1180 cubic centimeters.

__

Additional comment

The dimensions of the inside of the L are found by subtracting the given width of the legs from the outside dimensions.

 7 cm -4 cm = 3 cm . . . . inside height

  11 cm -5 cm = 6 cm . . . . inside width

You can also find the area of the base by extending one or the other of the lines to divide it into two rectangles. Extending the vertical line makes the left rectangle 7 cm high by 5 cm wide. The right rectangle is 4 cm high by 6 cm wide. Then the area is 7·5 +4·6 = 35+24 = 59, as above.

Angle ∠IKJ is 29.5 degrees for triangle IKJ.

A triangle is a three-sided polygon that consists of three edges and three vertices.

The given triangle is IKJ.

The angles are given as follow.

∠JIK = 53°,

∠IKJ = (82-5x), and

∠KJI = (7x+24)°.

We need to find the angle ∠IKJ .

By angle sum property of triangle, the sum of three angles is 180 degrees.

∠JIK+∠IKJ+∠KJI = 180

Fifty three plus eighty two minus five times of x plus seven times of x plus twenty four equal to one hundred and eighty.

53+82-5x+7x+24=180

Add the like terms

159+2x=180

One hundred fifty nine plus two times of x equal to one hundred eighty.

subtract 159 on both sides

2x=21

Divide both sides by 2.

x=10.5

So ∠IKJ is 82-5(10.5)=29.5 degrees.

Hence, the value of angle ∠IKJ is 29.5 degrees.

Answer:

Step-by-step explanation:

To prove this statement, we can use the contrapositive. The contrapositive of the statement "If a + b > 100, then a, b, or both must be greater than 50" is "If a and b are both less than or equal to 50, then a + b is less than or equal to 100."

To prove the contrapositive, we must show that if a and b are both less than or equal to 50, then a + b is indeed less than or equal to 100. This is easy to do, because if a and b are both less than or equal to 50, then the largest possible value for a is 50 and the largest possible value for b is 50. Therefore, the largest possible value for a + b is 50 + 50, which is equal to 100.

Since the contrapositive is true, it follows that the original statement must also be true. Therefore, we have proven that if a + b > 100, then a, b, or both must be greater than 50.
