Answer:

a. D = R \ {13}

b. D = [-9;+∞)

D = R \ { [tex]\frac{-1}{2}[/tex] }

Step-by-step explanation:

a. 13 - x ≠ 0

 x ≠ 13

D = R \ {13}

b. 9 + x ≥ 0

x ≥ -9

D = [-9;+∞)

c. 2x + 1 ≠ 0

x ≠ [tex]\frac{-1}{2}[/tex]

D = R \ { [tex]\frac{-1}{2}[/tex] }

Find the value of x.

A. 212
B. 148
C. 74
D. 52

Answers

Answer:

D.52

Step-by-step explanation:

i'm probably overcomplicating because i haven't dpne these problems in a while and i don't remember the formula names so sorry if it sounds confusing:

the angle inscribed in the circle has an angle of 64 degrees, so the angle of the minor arc that the inscribed angle creates has an angle of 128 degrees (angle of arc = 2 times angle of inscribed angle'

now using the formula for the tangent lines, x=(major arc-minor arc)/2, the major arc=360-minor arc=360-128=232 so we have (232-128)/2=104/2=52 so x=52 degrees

Answer:

D

Step-by-step explanation:

Draw the central angle from the two tangent points. That angle will be twice the size of 64. So the central angle is 128.

x is the supplement of 128 or 52 degrees. You can show this by proving that the the central angle + x + 90 + 90 = 360

Central angle + x = 180

128 + x = 180

x = 52

Answers

Answer:

10×18+8×18; You can also find the length of each side of the apartment, 18 and  10+8,  and then multiply 18(10+8)

Step-by-step explanation

The total area Room₁ and Room₂ = (A₁ + A₂) sq feet

                                                          = (180 + 144) sq feet

                                                          = 324 Sq feet.

In the given question

Length of the first room (l₁) = 18 feet

Width of the first room(w₁) = 10 feet

We know area of a rectangle is product of it's length and width.

Area of the first room A₁ = (l₁ × w₁) sq feet

                                       A₁ = (18 × 10) sq feet

                                       A₁ = 180 sq feet.

Length of the second room (l₂) = 18 feet

Width of the second room (w₂) = 8 feet

Area of the second room A₂ = (l₂ × w₂) sq feet

                                             A₂ = (18 × 8) sq feet

                                             A₂ = 144 sq feet.

∴The total area Room₁ and Room₂ = (A₁ + A₂) sq feet

                                                          = (180 + 144) sq feet

                                                          = 324 Sq feet.

Another way of finding the total area of the two rooms as we can see from the given figure both two rooms together form a square as the sides of the given sides which are 18 feet and (10 + 8) feet which is also 18 feet.

So, It is a square.

Area of a square = (side)²                        (area of a square is product of            

                                                                                     two adjacent sides)

Area = (18)² sq feet

        = 324 sq feet.

Andre wants to make a scaled copy of Jada's drawing so the side that corresponds to 4 units in Jada’s polygon is 8 units in his scaled copy.

Answers

Scaled drawing shows representation of the correct sizes of the original object either being reduced or enlarged by a given amount

The correct response to Andre is that each length of the sides of Jada's drawing should be multiplied by two to make a scaled copy of the drawing

The reason the response is correct is as follows:

Question: The parts of the question that appear missing is as follows;

1. Andre makes the statement, in order to obtain the scaled copy, should he add 4 units to each of the dimensions of the sides of Jada's drawing

The question is, what should be the response to Andre

The response is as follows:

When making a scale drawing, it should be noted that the original drawing and the scaled copy of the drawing are to be similar figures. That is the ratio of their corresponding sides should be constant

The ratio of the corresponding sides of the scale drawing Andre wants to make is 8 units/(4 units) = 2 : 1

Therefore, the correct response is Andre should multiply each of the lengths of the sides of Jada's drawing by two to make a scaled drawing as follows

[tex]\begin{array}{|c|c|c|}\mathbf{Length \ on \ Jada's \ drawing}& \mathbf{Length \times 2 =} &\mathbf{Length \ of \ Andre's \ scaled \ copy}\\&&\\12& 12\times 2 =&24\\10& 10\times 2 =&20\\7& 7\times 2 =&14\\6& 6\times 2 =&12\\5& 5\times 2 =&10\\4& 4\times 2 =&8\end{array}\right][/tex]

The lengths of Andre's scaled copy are 8 units, 10 units, 12 units, 14 units, 20 units, and 24 units

0.2x-8=0.4x-7
What is x?

Answers

Answer:

x = -5

Step-by-step explanation:

0.2x-8=0.4x-7

First, add 8 to both sides.

0.2x-8+8=0.4x-7+8

0.2x=0.4x-1

Next, subtract 0.4x from both sides.

0.2x-0.4x=0.4x-1-0.4x

-0.2x=1

Divide both sides by -0.2:

-0.2x/-0.2=1/-0.2

A farmer sells 7.2 kilograms of pears and apples at the farmer's market.
3 4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?

Answers

Answer:

3.8 kg of apples were sold by the farmer.

Step-by-step explanation:

Given-

Kilograms of pears: 3.4 kgs

Kilograms of apples: ?

Total: 7.2 kgs

Therefore:-

Kgs of apples + Kgs of pears = Total Kgs of fruits sold. (Given)

Kgs of apples + 3.4 kgs = 7.2 kgs (Substituting given values)

Kgs of apples = 7.2 kgs - 3.4 kgs (Taking known values to one side)

Kgs of apples= 3.8 kgs.

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?(A) A few children still use traditional wooden sleds.(B) Very few children wear any kind of protective gear, such as helmets, while sledding.(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.(D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.(E) Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
