HELP!!!! PLZ!!!!!!!!!!!!!!!!!

Answer:

8: C

9: D

10: C

11: D

Step-by-step explanation:

On number 8, the pattern is by starting from 3, and squaring it. Then you take that square and square it again. So 3 squared is 9, and then you square 9 which is 9 times 9 giving you 81. Then you square 81 giving you 6561.

9: Negative exponents work by flipping the number upside down, and then doing normal exponential work on the now denominator.

If the number is 5 to the power of -3, you are flipping 5 to 1/5 and then doing 5 to the power of 3 which is 5x5x5 giving you 125. Therefore the answer would be 1/125.

10 is the same thing as number 9 except backwards, so you flip 1/2^3 to 2^-3

11 is similar, except you have 3.471 times 1/10000

So you add 4 zeros in front of the 3.471 turning it into 0.0003471

Answer : The measure of angle MBT​ is 28°.

Step-by-step explanation :

As we see that the ∠NBM is equal to ∠MBT.

That means,

∠NBM = ∠MBT

Given:

∠NBM = (17x - 6)°

∠MBT = (5x + 18)°

According to question:

∠NBM = ∠MBT

(17x - 6)° = (5x + 18)°

17x - 5x = 18° + 6°

12x = 24°

x = 2°

So,

∠NBM = (17x - 6)° = [(17 × 2) - 6]° = 28°

∠MBT = (5x + 18)° = [(5 × 2) + 18]° = 28°

Hence, the measure of angle MBT​ is 28°.

Sales price of suit is equals to $216 after applying 10% discount.

" Discount is deduction  by some percent or amount in the original price of any product."

Formula used

Sales price = Marked price - discount amount

Discount = ( Marked price × discount %) /100

According to the question,

Marked price of the suit= $240

Discount %  on the suit =10%

Substitute the value in the formula we get,

Discount = (240 × 10) / 100

               = $24

Sales price = $240 - $24

                   = $216

Hence, Sales price of suit is equals to $216 after applying 10% discount.

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

(Hope this helps! ^^)

Answer:

[tex]\boxed {s = 5.1}[/tex]

Step-by-step explanation:

Solve for the value of [tex]s[/tex]:

[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]

-Use Distributive Property:

[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]

[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]

-Combine like terms:

[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]

[tex]s + 2.8 = 7.9[/tex]

-Subtract [tex]2.8[/tex] to both sides:

[tex]s + 2.8 - 2.8 = 7.9 - 2.8[/tex]

[tex]\boxed {s = 5.1}[/tex]

So, the value of [tex]x[/tex] is [tex]5.1[/tex].

Answer:

x = 20

Step-by-step explanation:

62 = (2+3x)

You want to isolate x, so first you subtract 2 from each side

60 = 3x

Now, you divide each side by 3

20 = x

There's your answer!

Answer:

#4

Step-by-step explanation:

1) The y intercept is 0.

2) Convert to slope-intercept form:

2x + 3y = 12

3y = -2x + 12

y = -2/3 x + 4

So the y-intercept is 4.

3) Write in point-slope form:

y + 4 = 2 (x - 1)

Now convert to slope-intercept form:

y + 4 = 2x - 2

y = 2x - 6

So the y-intercept is -6.

4) The y-intercept is 5.

So of the four lines, #4 has the largest y-intercept.

The line with an  x-intercept of -1 and a  y-intercept of 1 is C. x - y = -1

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept

Given the line x - y = -1, the x intercept is at y = 0, hence:

x - 0 = -1

x = -1

The y intercept is at x = 0, hence:

0 - y = -1

y = 1

The line with an  x-intercept of -1 and a  y-intercept of 1 is C. x - y = -1

6

Step-by-step explanation:

hcf stands for "highest common factor"

factors of 12= 1,2,3,4,6,12

factors of 30=1,2,3,5,6,10,15,30

factors of 48= 1,2,3,4,6,8,12,16,24

6 is the highest overlapping factor so its is the "hcf".

Answer:

the measure of each angle is 150.

Step-by-step explanation:

in order to find this you need to find the measure all the degrees which can be found with (n-2)x180

in this case this is (12-2) x 180

so you would get the total degrees in the inside is 1,800

then there are a total of 12 interior angles so divide 1,800 by 12 to get 150 for each interior angle (btw this is only possible since this is a regular polygon meaning that every one of the angles are the same )

6(x2-10x+25)+438-150   Adding 25 inside the parenthesis is really like adding 6(25)=150 to that side of the equation.  To keep the equation in balance, you have to subtract 150 from the other term.  Simplify

Answer:

x=19°

Step-by-step explanation:

Angles  ∡DBE ≅ ∡ACD= 3x  reason - angles with parallel arms

Angles ∡ADC and ∡ADB=95° are supplemental angles which means

∡ADC + ∡ADB=180° => ∡ADC = 180° - ∡ADB= 180°-95°= 85°

In the triangle we have ∡ADC + ∡ACD + ∡CAD = 180° =>

85 + 3x + 2x = 180 => 85 + 5x = 180 => 5x= 180-85 => 5x=95

x=95/5 => x=19°

Good luck!!!
