Step-by-step explanation:

so first find the circumference of the circle, which is 2 x pi x radius

after that, multiply your circumference by the height to find the curved surface area

now find the surface aread of the base and the top, which is just 2 x pi x radius x radius

Answer:

Step-by-step explanation:

The equation has to be

8x + 20 = 148                  Subtract 20 from both sides

8x = 148 - 20                  Combine

8x = 128                          Divide by 8

x = 128/8                        

x = 16

Answer:y =-3x/4+2

Step-by-step explanation:

Slope= -3/4

The line is passing through (0,2).

y-2=(x-0)*-3/4

Answer:

$7,000 at 7%; $13,000 at 8%

Step-by-step explanation

x: the amount invested at 7%

y: the amount invested at 8%

x + y = 20,000

7%.x + 8%.y = 1,530

⇒ x =7,000

y = 13,000

Answer:

solution: (0, -3, or -1)

Step-by-step explanation:

2(7s + 3) + 2(8s - 4) =

= 14s + 6 + 16s - 8 =

= 14s + 16s + 6 - 8 = 30s - 2 ← the end

Answer:

Each term is 2 greater than the term before it. Thus for any given term, an, our equation is:

an=2n

We can write this in a form closer to standard, by noting that a1=2, so we can make it dependent on a1..

an=a1+2(n−1)=2+2(n−1)

Answer:

n = - 11

Step-by-step explanation:

4 less than a number n is

n - 4 = - 15 ( add 4 to both sides )

n = - 11

Answer:

8.216 x 10⁻⁴

I think this is right scientific notation.

Using pythagorean theorem

[tex]\\ \sf\longmapsto x^2=11^2+11^2[/tex]

[tex]\\ \sf\longmapsto x^2=121+121[/tex]

[tex]\\ \sf\longmapsto x^2=242[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{242}[/tex]

[tex]\\ \sf\longmapsto x=15.4[/tex]

Step-by-step explanation:

Use the pythagorean theorem

[tex]a {}^{2} + b {}^{2} = c {}^{2} [/tex]

[tex]11 {}^{2} + 11 {}^{2} = c {}^{2} [/tex]

[tex]121 + 121 = c {}^{2} [/tex]

[tex]c = \sqrt{242} = 2 \sqrt{11} [/tex]

Answer:

What are the coordinates of the vertex of the function f(x) = x2 − 12x + 5?

Step-by-step explanation:

November 2021 EDGE

entered :

-|3x-9|+2=-4

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

-|3x-9|+2 = -4

Another term is moved / added to the right hand side.

To make the absolute value term positive, both sides are multiplied by (-1).

|3x-9| = 6

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |3x-9|

For the Negative case we'll use -(3x-9)

For the Positive case we'll use (3x-9)

STEP

3

:

Solve the Negative Case

-(3x-9) = 6

Multiply

-3x+9 = 6

Rearrange and Add up

-3x = -3

Divide both sides by 3

-x = -1

Multiply both sides by (-1)

x = 1

Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

(3x-9) = 6

Rearrange and Add up

3x = 15

Divide both sides by 3

x = 5

Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

x=1

x=5

I hope this help you

Answer: x= 1, 5

Step-by-step explanation:

First, isolate the absolute value. Subtract two from the equation to get -l3x-9l=-6, and then divide by -1 to get l3x-9l=6.

Since an absolute value measures how far away a value is from zero, it's always positive. For example, -10 and 10 have the same absolute value, 10, because they're both 10 units away from zero.

Because of this, you create two equations; 3x-9=6, and 3x-9=-6.

For the first equation, add 9 to 6 and divide that by 3 to get x=5.

For the second equation, add 9 to -6 and divide that by 5 to get x=1.

Answer:

4 quarters and 6 dimes

Step-by-step explanation:

4(0.25)+6(0.10)= 1.60

-8 < 2x-4 < 8

Add 4 to all sides:

-8 + 4 < 2x -4 + 4 < 8 + 4

Simplify :

-4 < 2x < 12

Divide all sides by 2:

-4/2 < 2x/2 < 12/2

Simplify to get the answer:

-2 < x < 6

Negative 7 = -7

Positive 2 = +2

Answer: It's C. 8

Trust me i've done the work for it :)

Answer:

x = 7

Step-by-step explanation:

8(5x + 2) = 296

40x + 16 = 296

40x = 280

x = 7

Answer:

x=7

Step-by-step explanation:

➼Okay, so first thing you need to do is to distribute the 8 to everything in the parentheses:

8(5x+ 2) = 296

8 times 5x

8 times 2

(8 x 5x) + (8 x 2) = 40x + 16

➼Now you solve for x

40x+16=296

➼to get rid of 40 you have to do the opposite and divide it by everything

40x+16=296

40/40=0

16/40=0.4

296/40=7.4

➼all adds up to x + .4 = 7.4 but to get the x alone you need to get rid of the .4, we'll do this by doing the opposite and subtract it from everything

.4-.4=0

7.4-.4=7

➼so in conclusion

x=7
