Answer:

ans = 9 degree

Step-by-step explanation:

81 + (4x) + (5x+18) = 180 (The sum of all angles of triangle is 180 degree)

81 + 4x + 5x + 18 = 180

99 + 9x = 180

9x = 180 - 99

9x = 81

x = [tex]\frac{81}{9}[/tex]

x = 9 degree

x = -1

Step-by-step explanation:

3(x - 6) - 8x = -2 + 5(2x + 1)

3x - 18 - 8x = -2 + 10x + 5

-5x - 18 = 10x + 3

-15x = 15

x = -1

Answer:

1. 0.8165 ; 2. 27.52 ; 3 = 3.8352 ; 4. 812.128 ; 5. 11.8513

Step-by-step explanation:

1. 3 - 2.1835 = 0.8165

2. 38.35 - (3.9 + 6.93) = 27.52

3. 8 - 4.1648 = 3.8352

4. 604 + 406.064 = 1010.064

604 - 406.064 = 197.936

1010.064 - 197.936 = 812.128

5. 18.35 - 6.4987 = 11.8513

Answer:

14

Step-by-step explanation:

It's a probability, divide favorable outcomes to total outcomes

Answer:

14%

Step-by-step explanation:

There are 7 sections of equal size.

The total number of possible outcomes is 7.

There is one single outcome that is desired, landing on 7.

probability of an event = (number of desired outcomes)/(total number of possible outcomes)

p(7) = 1/7 = 0.142857... = 14%

Answer: 14%

Answer:

A Taylor series approximation uses a Taylor series to represent a number as a polynomial that has a very similar value to the number in a neighborhood around a specified x value: f ( x ) = f ( a ) + f ′ ( a ) 1 ! ( x − a ) + f ′ ′ ( a ) 2 !

Answer:

  2 inches

Step-by-step explanation:

The area of the frame will be the difference between the area of the picture with frame, and the area of the picture without. We want that difference to be equal to the area of the picture without the frame.

Let x represent the width of the frame. The overall length and width of the picture will be increased by 2x when the frame is added. Then we have ...

  a = LW = (8+2x)(12+2x) . . . . area of picture and frame

  b = LW = (8)(12) . . . . . . . . . . area of picture

  a -b = b . . . . . . desired relationship between areas

Substituting and expanding the expressions for 'a' and 'b', we find ...

  a -2b = 0 . . . . subtract b

  (8 +2x)(12 +2x) -2(8)(12) = 0

  4x² +40x -96 = 0 . . . simplify

  x² +10x -24 = 0 . . . . . divide by 4

  (x -2)(x +12) = 0 . . . . factor

The positive value of x that makes this true is x = 2.

The width of the frame is 2 inches.

Answer:

120 - 15% × 120 = x

Step-by-step explanation:

All given answers are incorrect.

15% means 0.15

She is not subtracting 15% or 0.15 from 120.

She is subtracting 15% of 120 from 120.

The correct answer is

120 - 15% × 120 = x

Answer:

A=25

Step-by-step explanation:

8-3=5

25/5=5

a=25

Answer:

A = 25

Step-by-step explanation:

To solve this equation, we have to find a number that can replace a that makes the equation true.

So, what number would fit?

Well, since a 5 is being divided by a, we have to find a number that 5 can  divided by 5 that gets 5.

This way, you can add 5 to 3 and get 8

Well, 5 x 5 = 25

So, 25 / 5 = 5

So, if we set a to 25, the equation is true

25 / 5 =5

5 + 3 = 8

Correct Answer: 25

Answer:

The 2nd paragraph has the straightforward answer, technically.

This is an example of gross domestic product and today's marketing. When a product is usually paid more money to manufacture than it costs to actually sell. However, the usual difference between manufacturing cost and sales cost is on average is at most 5 - 15% of the manufacturing cost.

The second problem however is just the perfect example of sales and sales tax. The diamond ring is on sale for 30% off in this case, because 290 divided by its percent is equal to 30%, the remaining amount.

Answer:

x = 80.34 (2 dp)

Step-by-step explanation:

[tex]2\ln(x)+7=\ln(4x)+10[/tex]

[tex]\implies \ln(x^2)+7=\ln(4x)+10[/tex]

[tex]\implies \ln(x^2)-\ln(4x)=10-7[/tex]

[tex]\implies \ln\left(\dfrac{x^2}{4x}\right)=3[/tex]

[tex]\implies \ln\left(\dfrac{x}{4}\right)=3[/tex]

[tex]\implies e^{\ln\left(\dfrac{x}{4}\right)}=e^3[/tex]

[tex]\implies \dfrac{x}{4}=e^3[/tex]

[tex]\implies x=4e^3[/tex]

[tex]\implies x=80.34 \textsf{ (2 dp)}[/tex]

B displays correct solutions for x² +9x +12 = 6

step-by-step explanation:

[tex]\rightarrow \sf x^2 + 9x + 12 = 6[/tex]

[tex]\rightarrow \sf x^2 + 9x +12 -6 = 0[/tex]

[tex]\rightarrow \sf x^2 + 9x + 6 =0[/tex]

use the formula:   [tex]\sf \bold{x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{2a } \ \ when \ \ \ ax^2 + bx + c = 0}[/tex]

[tex]\rightarrow \sf x = \dfrac{ -9 \pm \sqrt{(-9)^2 - 4(1)(6)}}{2(1)}[/tex]

[tex]\rightarrow \sf x = \dfrac{ -9 \pm \sqrt{57}}{2}[/tex]

[tex]\rightarrow \sf x = \dfrac{ -9}{2} +\dfrac{\sqrt{57}}{2}[/tex]   ;  [tex]\sf x = \dfrac{ -9}{2} -\dfrac{\sqrt{57}}{2}[/tex]

Simplify:

36÷2=1, making 2 a good 2nd term

There are 2 candy bars every 1 lollipop.

1:2

1:2 is the ratio of lollipops to candy bars.

The relationship in quantity, amount, or size between two or more things.

Given that there are 18 lollipops and 36 candy bars,

Ratio = 18/36 = 1/2

Hence, 1:2 is the ratio of lollipops to candy bars.

Answer:

Anything before 0 is negative. In this case we’re trying to “plot” - 1 2/3. It has to be between -2 and 0 on this plot.

Now lets imagine we have a center line between -2 and 0.
You’d get
-2, -1, 0

Now using that benchmark/ estimate, go towards the LEFT between -1 and -2. Now when reached about half way, go forward for a bit more and you should receive it.

1. Create a grid that is 5 squares wide by 2 squares tall. Shade 8 squares as shown above.

 A. Look at the shaded:total in the gizmo table. What decimal and percent are modeled by the shaded squares?

Decimal part =

10 squares

8 shaded

0.2=2 squares shaded

so

8 squares shaded = 0.8

Percent part =

if 100% = 1 whole

1 whole = 10 blocks in gizmo table

then

8 blocks in gizmo table = 80%

since

1 block = 10%

10%x8=80

80%

B. Look at the unshaded:total row. What decimal and percent by the unshaded squares?

Decimal part:

If there are 2 unshaded squares

and we know that 1 square = 0.1

then, 2 squares = 0.2

0.2

Percent part:

if we know that 10 blocks = 1 whole

and 1 block = 10%

then 2x10%=20%

20%

1. The Gizmo gives two equivalent (equal) fractions — simplified and unsimplified — for the shaded:total and unshaded:total ratios. Record them below. (to see why these are equivalent, notice how many shaded and unshaded squares are in each row of the grid.)

x = 1

explanation:

[tex]\sf \rightarrow \dfrac{3}{x} -1 = 2[/tex]

[tex]\sf \rightarrow \dfrac{3}{x} = 2+1[/tex]

[tex]\sf \rightarrow \dfrac{3}{x} = 3[/tex]

[tex]\sf \rightarrow {3} = 3(x)[/tex]

[tex]\sf \rightarrow \dfrac{3}{3} = (x)[/tex]

[tex]\sf \rightarrow x = 1[/tex]

checking if x = 1,

[tex]\sf \rightarrow \dfrac{3}{1} -1 = 2[/tex]

[tex]\sf \rightarrow3 -1 = 2[/tex]

[tex]\sf \rightarrow 2 = 2[/tex]

→ Hence proved x : 1 as L.H.S = R.H.S

Step-by-step explanation:

[tex] \frac{3}{x} - 1 = 2 \\ [/tex]

[tex] \frac{3}{x} - 1 + 1 = 2 + 1 \\ \frac{3}{x} = 3[/tex]

[tex]3 \times x = 3 \times 1 \\ 3x = 3[/tex]

Dividing both sides by 3, we get

[tex] \frac{3x}{3} = \frac{3}{3} \\ x = 1[/tex]
