Answer:

x = 12

Step-by-step explanation:

Angles and Lines

The figure attached below has been completed with the angle y to support the calculations to come.

The sum of the interior angles of a rectangle is 180°. Applying on triangle PQR:

30 + 4x + 2 + y = 180

Simplifying:

32 + 4x + y = 180

Solving for y:

y = 180 - 32 - 4x

y = 148 - 4x

Angles y and 8 + 6x are a linear pair, i.e. their sum is 180°, thus:

y + 8 + 6x = 180

Substituting y from the equation above:

148 - 4x + 8 + 6x = 180

Simplifying:

156 + 2x = 180

Dividing by 2:

78 + x = 90

Subtracting 78:

x = 90 - 78

x = 12

Answer:

(D) The bottom graph, and (A) The top table.

Step-by-step explanation:

The easiest way to pick out the wrong answers is simply through substitution. Substitute the input into the x part of the equation that is given and if it doesn't match up with y everytime, then it is incorrect.

From table A (top table), the input x can be substituted into y = x + 2 which will come out as the output so it is correct.

For table A:

x = -3 → y = x + 2 → y = (-3) + 2 → y = -1 = -1

x = -2 → y = x + 2 → y = (-2) + 2 → y = 0 = 0

x = -1 → y = x + 2 → y = (-1) + 2 → y = 1 = 1

x = 0 → y = x + 2 → y = (0) + 2 → y = 2 = 2

x = 1 → y = x + 2 → y = (1) + 2 → y = 3 = 3

Since the table matches up with the inputs and outputs of the table, it is a correct answer.

For table B:

x = 3 → y = x + 2 → y = (3) + 2 → y = 5 = 5

x = 4 → y = x + 2 → y = (4) + 2 → y = 6 ≠ 7

x = 5 → y = x + 2 → y = (5) + 2 → y = 7 ≠ 9

x = 6 → y = x + 2 → y = (6) + 2 → y = 8 ≠ 11

x = 7 → y = x + 2 → y = (7) + 2 → y = 9 ≠ 13

5 out of the 6 y values of the table do not match the equation, so table B must be incorrect.

Graph C:

Notice how you can see the line cross the x, and y axis. When the line crosses the x axis, it is an x intercept which means y is 0. When the line crosses the y axis, it is a y intercept which means x is 0.

Since the line crosses the y axis at 2, this means that an x of 0 must lead to a y of 2 which it does.

x = 0 → y = x + 2 → y = (0) + 2 → y = 2 = 2.

But the x intercept doesn't match up as shown here.

y = 0 → y = x + 2 → (0) = x + 2 →

0 – 2 = x + 2 – 2 → -2 = x → x = -2 ≠ -1

When graphing the line y = x + 2, it's x intercept should be (-2,0). While on this graph, it's (-1,0). This means that this graph is incorrect which leads to D being another correct answer.

✓ Table A: y = x + 2

× Table B: y = 2x – 1

× Graph C: y = 2x + 2

✓ Graph D: y = x + 2

I need to find the missing angle thank you

Answers

Answer:

The missing angles measure is 70 degrees

Step-by-step explanation:

First we must complete the left triangles last measure:

60+65+x=180

x=55

Then we have to make all of those three middle angles equal 180:

55+50+y=180

105+y=180

y=75

Now we add 75 to 35 to the missing angle to get 180:

75+35+z=180

110+z=180

z=70

The missing angles measure is 70 degrees

The four walls and the ceiling of a cubical room need to be painted. If the height of the room is 4 m , and painting costs ₹ 20/m2 20 / m 2 , what is the total cost of painting the room?

Answers

Answer:

₹ 1920

Step-by-step explanation:

Since the room is cubical in nature, we will find the total surface area of the room

Total surface area of the cubical room = 6L²

L is the length of one side of the room

Given

L = 4m

Total surface area of the cubical room = 6(4)²

Total surface area of the cubical room = 6×16

Total surface area of the cubical room = 96m²

If the painting costs ₹ 20/m², this means;

₹ 20 = 1m²

For the total room:

x = 96m²

Divide both expressions

20/x = 1/96

x = 20×96

x = 1920

Hence the total cost of painting the room ₹ 1920

At a gas station, all chips are marked down 10%. A customer brings a bag of chips with a regular price of $2.19 to the register. After the 7% sales tax on the final price, how much does the customer pay for the bag of chips ?

Answers

Answer: $2.11

Step-by-step explanation:

A customer brings a bag of chips with a regular price of $2.19 to the register which is marked down 10% the price to pay will be:

= $2.19 - (10% × $2.19)

= $2.19 - $0.219

= $1.971

After a 7% sales tax on the final price, the amount paid by the customer will be:

= $1.971 + (7% × $1.971)

= $1.971 + $0.13797

= $2.11

X^2+3x+4=(x+a)^2+b what is A and B equal please help me

Answers

Answer:

a = 1.5, b = 1.75

Step-by-step explanation:

Expand the right side using FOIL, then compare the coefficients of like terms with the expression on the left side.

(x + a)² + b

= x² + 2ax + a² + b , then compare to

x² + 3x + 4

Comparing the coefficients of the x- terms

2a = 3 ( divide both sides by 2 )

a = 1.5

Comparing the constant terms

a² + b = 4

1.5² + b = 4

2.25 + b = 4 ( subtract 2.25 from both sides )

b = 1.75

The tape diagram below represents 100%.100%?What percent is represented by the shaded area?% Wilona was married to Wilbur for 40 years. She was devastated when he passed away. She had been very reliant on him and left all their business matters to him. She had always been a religious person and turned to her faith for solace.She was visited by her local priest, Father Devout. She talked about her situation with him and concluded that she should sell her matrimonial home and move into a small unit. Father Devout was himself looking for a new home after the church had informed him that it would be selling the bungalow adjacent to the church building in which he currently lived as a cost- cutting exercise. He mentioned this fact in passing and Wilona insisted that she sell her house to him. When he asked how much she would want for the property, she said she had no idea of its worth. However, she had heard a neighbour say that a house in the street had sold for about $200,000, but, because she knew that her house would go to someone deserving, she would sell it to him for $100,000. This was in fact half its true value. She wouldnt take no for an answer and Father Devout knew her to be someone who would obstinately insist on something once her mind was made up.Wilona needed a bridging loan to purchase her unit. She does not trust banks and instead approached Sly, a fellow parishioner. Sly was a wealthy businessman, who told her he would give her the necessary funds if she signed a receipt for it so he would have something to show the taxman. In fact, the receipt was a basically-worded loan document, which provided that she was liable for interest at twice the rate that she could have obtained from a bank. Wilona signed the document without reading it because she thought Sly, as a fellow churchgoer, was a good man.Wilonas son and daughter have just flown in from their respective homes overseas and discovered what Wilona has been doing.
