What is the perimeter of triangle ABC?
9 + /21 units
O 9 + 29 units
9 + 41 units
9 + 61 units

Answers

The perimeter of the triangle ABC is the sum of the side lengths of the triangle

Using the assumed values, the perimeter of the triangle is 12 units

How to determine the perimeter?

Assume the side lengths of the triangle are:

AB = 3

BC = 4

CA = 5

Then the perimeter (P) would be:

P = AB + BC + CA

This gives

P = 3 + 4 + 5 = 12

Hence, the perimeter of the triangle is 12 units

Use the following information to find PD and EQ.
AP = 3, PQ = 5, QB = 7, CP=2, and QD = 14
Find PD and EQ

Answers

Answer:

[tex] PD = 18 [/tex]

[tex] EQ = 4 [/tex]

Step-by-step explanation:

Given:

AP = 3,

PQ = 5,

QB = 7,

CP = 2,

QD = 14

Required:

1. PD

2. EQ

SOLUTION:

1. Based on Intersecting Chords Theorem,

[tex] AP*PB = CP*PD [/tex]

AP = 3

PB = PQ + QB = 5 + 7 = 12

CP = 2

PD = ?

Plug in the values into the equation

[tex] 3*12 = 2*PD [/tex]

[tex] 36 = 2*PD [/tex]

Divide both sides by 2

[tex] \frac{36}{2} = PD [/tex]

[tex] 18 = PD [/tex]

[tex] PD = 18 [/tex]

b. Based on Intersecting Chords Theorem,

[tex] EQ*QD = AQ*QB [/tex]

EQ = ?

QD = 14

AQ = AP + PQ = 3 + 5 = 8

QB = 7

Plug in the values into the equation

[tex] EQ*14 = 8*7 [/tex]

[tex] EQ*14 = 56 [/tex]

Divide both sides by 14

[tex] EQ = \frac{56}{14} [/tex]

[tex] EQ = 4 [/tex]

Tell which angles are congruent to the given angle measure. ​

Answers

Generally:

- Vertical angles are congruent.   An example of vertical angles on the diagram are angles 1 and 4; they are opposite each other on the two intersecting lines.

When two parallel lines are intersected by a transversal:

- Corresponding angles are congruent.   Corresponding angles are angles on the same side of the transversal with corresponding positions, such as angles 2 and 5 in the diagram.

- Alternate interior angles are congruent.   Angles 3 and 5 are an example of alternate interior angles on the diagram.  They are contained within the interior of the two parallel lines, and are on opposite sides of the transversal.

- Alternate exterior angles are congruent.   These angles lie on the outside of the parallel lines and on opposite sides of the transversal.  Angles 1 and 7 are an example of alternate exterior angles.

Looking at the diagram, we can recognize that our given angle of 56° creates a vertical angle pair with angle 7; these angles are congruent.  Additionally, since corresponding angles are congruent, angles 4 and 7 are congruent.  Notice that angle 4 creates a vertical angle pair with angle 1, and that angle 1 also corresponds to the given angle.

Answer:

The angles which are congruent to the given angle measure are:

∠1, ∠4 and ∠7

divide a line of 1.8m into three parts in the ratio of 5:7:8​

Answers

Answer:

0.45 m, 0.63 m, 0.72 m

Step-by-step explanation:

Let the three parts of the line be 5x, 7x and 8x

Therefore,

5x + 7x + 8x = 1.8

20x = 1.8

x = 1.8/20

x = 0.09

5x = 5*0.09 = 0.45 m

7x = 7*0.09 = 0.63 m

8x = 8*0.09 = 0.72 m

The half-life of the radioactive element unobtanium-43 is 10 seconds. If 48 grams of unobtanium-43 are initially present, how many grams are present after 10
seconds? 20 seconds? 30 seconds? 40 seconds? 50 seconds?

Answers

Answer:

At time, 10 seconds, the mass remaining is 24 grams

At time, 20 seconds, the mass remaining is 12 grams

At time, 30 seconds, the mass remaining is 6 grams

At time, 40 seconds, the mass remaining is 3 grams

At time, 50 seconds, the mass remaining is 1.5 grams

Step-by-step explanation:

Given;

initial mass of the radioactive element  = 48 grams

half life, t = 10 seconds

time of decay (s)                          remaining mass of the  radioactive element

0 ------------------------------------------------- 48 grams

10------------------------------------------------- 24 grams

20 ------------------------------------------------- 12 grams

30 -------------------------------------------------- 6 grams

40 --------------------------------------------------- 3 grams

50 ----------------------------------------------------- 1.5 grams

60------------------------------------------------------0.75 grams

Thus;

At time, 10 seconds, the mass remaining is 24 grams

At time, 20 seconds, the mass remaining is 12 grams

At time, 30 seconds, the mass remaining is 6 grams

At time, 40 seconds, the mass remaining is 3 grams

At time, 50 seconds, the mass remaining is 1.5 grams

In a department store the owner paid $15 for 1 kg of sugar. The owner marked the price up by 10% for the customers. How much does he charge for 1kg of sugar?

Answers

First you need to work out what 10% of $15 is. You can do this on a calculator by converting the fraction into decimal which is 0.10 and then multiplying 15 by 0.10:

15 x 0.10 = 1.50

Then since the owner increased the price by 10%, we simply do 15 + 1.50 which gives us 16.50

Therefore the owner charges $16.50 for 1kg of sugar


What is the slope of the line?y=1/3x+2

Answers

Answer:

THis equation is in slope-intercept form (y=mx+b)

in this equation m represents the slope.

Therefore 1/3 is the slope

1/3

Step-by-step explanation:

Answer: m = 1/3

Step-by-step explanation: Since the equation of this line is written

in slope-intercept or y = mx + b form, its slope or m is represented

by the coefficient of the x term which in this case is 1/3.

For these problems,
x
will represent the number of items and
y
will represent the money.

The fixed costs for a certain item are $100 per week. The cost to produce each item is $6 per item.

Using this information, what is the cost equation? Give your answer in slope-intercept form:

Answers

Answer:

y = 6x + 100

Step-by-step explanation:

Slope-intercept form is y = mx + b, where m is the cost to produce each item and b is the fixed cost. Let's input the given values for m and b into the equation:

y = 6x + 100

This is the cost equation. $6 multiplied by x amount of items pluss the fixed cost of $100 gives you the total cost (y) to produce x amount of items.

Many houses today are constructed by builders who own and develop an area of homes. The builders often hire teams of workers who go from site to site specializing in certain tasks. To make this easier and to make the cost of materials less expensive, the houses are all built based on the same floor plan and the exteriors only have minor variations in styles and materials. Consequently, the interior details as well as the exteriors look very much the same from house to house. The overall result of this system is a lack of charm and individuality of homes in such housing additions.
