Answer:

C

Step-by-step explanation:

The surface area of a cylinder is given by the formula:

[tex]SA=2\pi rh+2\pi r^2[/tex]

Where h is the height and r is the radius of the cylinder.

The given radius is 6 and the height is 24.

We are also using 3.14 for π.

Therefore;

[tex]SA\approx 2(3.14)(6)(24)+2(3.14)(6)^2[/tex]

Evaluate:

[tex]SA\approx1130.4\approx 1130[/tex]

The answer is C.

Answer:

(1, 2 ), (2, 1 )

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

x² + y² = 5 → (2)

Rearrange (1) expressing y in terms of x by subtracting x from both sides

y = 3 - x → (3)

Substitute y = 3 - x into (2)

x² + (3 - x)² = 5 ← expand and simplify left side

x² + 9 - 6x + x² = 5

2x² - 6x + 9 = 5 ( subtract 5 from both sides )

2x² - 6x + 4 ( divide through by 2 )

x² - 3x + 2 = 0 ← in standard form

(x - 1)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

Substitute these values into (3) for corresponding values of y

x = 1 : y = 3 - 1 = 2 ⇒ (1, 2 )

x = 2 : y = 3 - 2 = 1 ⇒ (2, 1 )

Answer:

solve the equation by multiplying and arranging.

I didn't saw the question properly but I think it's the right question.

Answer:

t = 3

Step-by-step explanation:

105 = -5t^2 -10t + 180

-75 = -5t^2 -10t

15 = t^2 +2t

t^2 +2t -15 = 0

(t+5)(t-3)

t = -5, 3

There's no such thing as negative time so you use the positive answer

Answer:

B

Step-by-step explanation:

The value of the polynomial for x = 3 is the value of P(3)

P(3) = 2(3)³ - 7(3)² + 7(3) - 12 = 54 - 63 + 21 - 12 = 0 → B

Answer:

29 multiple choice questions, 6 word problems

Step-by-step explanation:

2x + 7y = 100

x + y = 35

y = 35 - x

2x + 7 (35 - x) = 100

2x - 7x + 245 = 100

-5x = -145

x = 29

29 + y = 35

y = 6

Answer:

u can prove using SAS congruency

Step-by-step explanation:

Ae=Ae common

BE=DE (E MID POINT)

Angle E=angle E (90 degree)

The ΔBAE is congruent to ΔDAE.

Given to us,

E is the midpoint of ,

AC⊥ BD,

As given E is the midpoint of the line [tex]\overline{BD}[/tex],

So, BE = ED,

further, line AE = AE, because this is the common line between the two triangles.

Also, ∠BED =∠DEA =90°, as AC⊥ BD.

Therefore, the ΔBAE is congruent to ΔDAE.

Answer:

X = 60°

Step-by-step explanation:

the angle you are looking for is a corresponding angle to the angle given (121°)

2x + 1 = 121

121 - 1 = 2x

121 - 1 = 120

2x = 120

120/2 = 60

X = 60

Answer:

{2, 3, 4, 6, 8, 9, 12, 18}

Step-by-step explanation:

If A= {x: xis a factor of 72}

A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}

If B= {x: 2x+3<2x-3).

-2x+3 <2x-3

Answer:

34

Step-by-step explanation:

40 * .15= 6

40-6 = 34

okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number

40*.15= 6

then subtract 6 to the original amount

40-6=34

Answer:

8 Seconds

Step-by-step explanation:

Since Jimmy runs 8 meters per second, we can multiply 8x8 to find where he will be after 8 seconds.

8x8 = 64

Since Jimmy's little brother runs 3 meters per second, we can multiply 3x8 to find where he will be after 8 seconds.

3x8 = 24

But, remember, Jimmy's little brother had a 40 meter head start. So we have to add 40 to his total.

24+40 = 64

Since Jimmy and his little brother's totals are both the same, Jimmy will catch up to his little brother after 8 seconds.
