Find the perimeter of the triangle as both a decimal and in simplest
radical form

Answer:

  (a)  24%

Step-by-step explanation:

You want the percentage of people in the Decades slice of a circle graph if it represents 96 people. The other slices represent 128, 72, 52, 24, and 28 people.

The fraction in the second category is the ratio of the number in that category to the total number. The percent is the fraction multiplied by 100%.

  96/(128 +96 +72 +52 +24 +28) × 100% = 96/400 × 100% = 24%

The Decades slice of the circle would be 24%, choice A.

The grades that Angie need to receive in her next test so that her average is 92 is 91.

The average is defined as the mean value a given data set. The formula to calculate the mean of a given data set is:

Average = Sum of the observations / Total number of observations

Assume the marks that Angie needs in her next test is represented by x.

Given that Angie has reviewed grades of 88, 96, 92, and 93 on her last 4 tests. Therefore, the grades she need to receive in her next test so her average is 92 is:

Average = Sum of the grades of all test / Total Number of test

92 = (88+96+92+93+x)/5

460 = 369+x

460 - 369 = x

x = 91

Hence, she needs 91 grades in her next test.

Step-by-step explanation:

The sum of the capitals would be $530400.

The formula to calculate the simple interest is -

I = PRT/100

Given is that a capitalist has two capitals that differ in $221,000. The largest of them imposes it at 20% per year and the smallest at 16% per year, so after 3 years, the amount produced by the largest is double what the smallest produces.

We can write the amount produced by largest as -

A = P(1 + rt)

A = 221000(1 + 0.2 x 3)

A = 221000 x 1.6

A = 353600

Amount generated by smallest -

a = 353600/2

a = 176800

Their sum would be -

A + a = 530400

Therefore, the sum of the capitals would be $530400.

The amount you made per share is $8.50.

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

Initial amount = $63.00

Final amount = $71.50

To calculate the profit made, we need to find the difference between the selling price and the buying price per share, and then multiply by the number of shares.

The difference in price per share is:

Difference = $71.50 - $63.00

Evaluate the difference

Difference = $8.50

A cross section of a cube that is a regular hexagon can only be obtained if the plane passes through the cube at a 60-degree angle with respect to its edges. If a plane is placed in this manner, it will intersect six of the cube's edges at their midpoints, producing a regular hexagon cross section.

The plane that passes through three edges of a cube to produce a regular hexagonal cross section must intersect the edges of the cube at 60 degree angles. This can be achieved if the plane is aligned with the diagonal of one of the faces of the cube, passing through the opposite vertices of the face.

This configuration of the plane will result in a regular hexagonal cross section of the cube as each vertex of the hexagon will correspond to one of the vertices of the cube, and each side of the hexagon will intersect two edges of the cube at 60 degree angles.

Answer:

F = 29

E= 151

D = 90

Step-by-step explanation:

For F:

The angle F is on a 180 degree angle with a degree next to it that is 151. To get the value F subtract 180-151 and you get 29.

For E: If F is 29 then the angle opposite of F is also 29. So again to find the measure of angle E, subtract 180 minus 29 and you get 151.

For D: D is also lying on a 180 degree angle. The angle next to it is 90. To get 180 add 90. 90 is the measure of angle d.

Answer:

-----------------------------------

Angle d is linear pair with a right angle, therefore:

Angle e is vertically opposite with 151° and therefore they are congruent:

Angle f is adjacent with 151° and forming a linear pair, therefore:

In the word problems given above, the results are:

1) Let's call the number we're looking for "x". According to the problem, "three times a number" is the same as 60 minus 21, which is 39. So we can write the equation:

3x + 21 = 60

Subtract 21 from both sides:

3x = 39

Divide by 3:

x = 13

Therefore, the number we're looking for is 13.

2)

Let's call the number we're looking for "x" again. According to the problem, "three times the difference between a number and three" is the same as "four times the number". So we can write the equation:

3(x - 3) = 4x

Simplify:

3x - 9 = 4x

Subtract 3x from both sides:

-9 = x

Therefore, the number we're looking for is -9.

3)

Let's call the first of the three consecutive integers "x". The next two would be x+1 and x+2. According to the problem, their sum is 48, so we can write the equation: x + (x+1) + (x+2) = 48

Simplify:

3x + 3 = 48

Subtract 3 from both sides:

3x = 45

Divide by 3:

x = 15

So the three consecutive integers are 15, 16, and 17. To answer the second part of the question, we can substitute these values into the given expression:

3m - z(1st) = 3(16) - 15(15) = 48 - 225 = -177


4)
Let's call the smallest of the three consecutive odd integers "x". The next two would be x+2 and x+4. According to the problem, twice the smallest is seven more than the largest, so we can write the equation:

2x = (x+4) + 7

Simplify:

2x = x + 11

Subtract x from both sides:

x = 11

So the three consecutive odd integers are 11, 13, and 15. The middle number is 13.


5)
Let's call the width of the rectangle "w". According to the problem, the length is 3 cm more than the width, so the length is w + 3. The perimeter is the sum of all four sides, which is:

P = 2w + 2(w + 3) = 4w + 6

We know that the perimeter is 22 cm, so we can write the equation:

4w + 6 = 22

Subtract 6 from both sides:

4w = 16

Divide by 4:

w = 4

So the width is 4 cm, and the length is 7 cm (since it's 3 cm more than the width). To find the area, we use the formula:

A = (L)(W) = (7)(4) = 28 square cm


6)

Let's denote the length of side a as x. Then we know that side b is 3 times the length of side a, or 3x, and side c is 1 more than twice the length of side a, or 2x+1.

Since the perimeter of the triangle is 43 inches, we can write the equation:

a + b + c = 43

Substituting in our expressions for b and c, we get:

x + 3x + 2x + 1 = 43

Simplifying the left-hand side, we get:

6x + 1 = 43

Subtracting 1 from both sides, we get:

6x = 42

Dividing both sides by 6, we get:

x = 7

thus:

a = 7

b= 3x = 21; na d

c = 2x + 1 = 14+1

c = 15

Thus the sum of sides a and b =
21 + 7
= 28

Answer: 39%

Step-by-step explanation:

0.058% x 663 seats = 39%

3.1 The cash price of the NISSAN NP300 is R221,180 (incl. VAT).

3.2. it would take approximately 6.67 years to pay off the vehicle through instalments.

A deposit of approximately R22,282.70 would be needed if the financing plan requires a 10% deposit

3.1 The cash price of the NISSAN NP300 is R221,180 (incl. VAT).

3.2 The given information does not explicitly state the number of years for the instalment plan, but it does provide the number of months (80) and the total payment amount (R303,007). Assuming a monthly payment plan, we can calculate the number of years as follows:

Number of years = Number of months / 12

Number of years = 80 / 12

Number of years ≈ 6.67 years

So it would take approximately 6.67 years to pay off the vehicle through instalments.

To calculate the deposit needed, we need to subtract the residual amount from the total cash price. From the given information, the total payment is R303,007 and the residual is R80,180, so:

Cash price = Total payment - Residual

Cash price = R303,007 - R80,180

Cash price = R222,827

So the cash price is slightly higher than the advertised price of R221,180, likely due to financing fees or interest. To determine the deposit needed, we can assume a specific percentage of the cash price that must be paid upfront. For example, if the deposit required is 10% of the cash price, then:

Deposit = 0.1 x Cash price

Deposit = 0.1 x R222,827

Deposit = R22,282.70

So a deposit of approximately R22,282.70 would be needed if the financing plan requires a 10% deposit.

The equation below can be set up to calculate this.

Tan(angle) = 80 ft / (200 ft – 4 ft)

Solving for the angle, we get:

angle = tan-1(80 ft / 196 ft (ca. 60 m))

angle = tan-1(0.408163265)
