A cylinder of base radius 4cm is opened at one end . If the ratio of the area of it's base to that of it's curved surface area is 1:4, Calculate the height of the cylinder​

Answer:

two real roots

Step-by-step explanation:

y = -2x^2 + 9x - 7

This is in the form

ax^2 +bx+c

a = -2  b = 9  c = -7

The discriminant is

b^2 -4ac

(9)^2 - 4(-2) (-7)

81 - 56

25

Since the discriminant is greater than zero, there are two real roots

Step-by-step explanation:

there are 8 oatmeal cookies out of the 24 in the jar so the probability of pulling an oatmeal cookie out is 8/24 = 1/3

Then we have 23 cookies in the jar and 12 are chocolate chip

1/3 * 12/23 = 4/23

Answer:

5

Step-by-step explanation:

For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.

5x -2y= 30

When x=8,

5(8) -2y= 30

40 -2y= 30

40 -30= 2y (bring constant to 1 side)

2y= 10 (simplify)

y= 10 ÷2

y=5

Thus the missing value is 5.

Answer:

Step-by-step explanation :

Ratio = 3x : 4x

Answer:

60 and 80 degrees.

Step-by-step explanation:

The other 2 angles have the sum : 360 - (140 + 80)

= 360 - 220

= 140.   (because the 4 angles in a quadrilateral add up to 360).

As  the other 2 angles are in the ratio 3:4 one angle = 3/7 of 140 and the other is 4/7 of 140.

This is equal to 3 *20 and 4 * 20 = 60 and 80 degrees.

Answer:

3 servings

Step-by-step explanation:

Take the number of pounds and divide by the size of the servings

3/4 ÷ 1/4

Copy dot flip

3/4 * 4/1

3/1 * 4/4

3 servings

Answer:

3

Step-by-step explanation:

To find this out, you need to use division. Divide 3/4 by 1/4.

3/4 divided by 1/4 equals 3.

So there are 3 1/4 pound servings in 3/4 pounds of walnuts.

Answer: (1) There are 233 parking spots on the top level

(2) There are 72 parking spots reserved for drivers with disabilities

(3) There are 970 spots for hourly parking

(4) He would spend $7200 for parking in a year

Step-by-step explanation: In the first instance, there is a total of 1327 parking spots altogether allocated into various categories.

(1) There are 6 levels in all, and the first level has 162 parking spots. herefore the remaining 5 levels would have 1165 parking spots left as shown below;

Remainder = 1327 - 162

Remainder = 1165

If however the remaining 1165 parking spots are distributed equally among the other 5 levels, then each level would have 233 parking spots each as shown below;

Five levels = 1165

Each level = 1165/5

Each level = 233

Therefore the top level has 233 parking spots

(2) On each level (out of all 6 levels), there are 12 spots reserved for drivers with disability. Therefore at all parking levels you would have 72 spots as shown;

Reserved spot per level = 12

Reserved spot for 6 levels = 12 * 6

Reserved spot for 6 levels = 72

Therefore there are 72 spots reserved for driver with disability

(3) Other than the spots reserved for drivers with disability (72), there are 285 parking spots for monthly rental. The rest are for hourly parking, and this is calculated as shown;

Hourly parking + monthly rental + reserved parking = 1327

Hourly parking + 285 + 72 = 1327

Hourly parking + 357 = 1327

Hourly parking = 1327 - 357

Hourly parking = 970

Therefore there are 970 spots available for hourly parking.

(4) If the daily parking rate is $30, and Jack parks his car for 5 days in a week, then he would spend

30 * 5 = 150

If he parks for 4 weeks in a month, then he would spend

150 * 4 = 600

Therefore to pay for parking in a year (12 months) he would spend

600 * 12 = 7200

Therefore he would spend $7,200 for parking in a year

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ √3 × √5 × √6​

Simplify the expression, then the value of the expression will be given as,

⇒ √3 × √5 × √(3 ×2)

⇒ √3 × √5 × √3 × √2

Answer:

15x + 14y + 36 = 0

Step-by-step explanation:

As we travel from the point (-8, 6) to the point (6, - 9), the increase in x (the "run") is 14 and that in y (the "rise") is -15.  Thus, the slope of the line segment connecting these two points is m = rise / run = -15 / 14.

Let's use the point (6, -9) and the slope m = -15/14 to write the equation of this line:

Adapting y = mx + b, we get:  

-9 = (-15/14)(6) + b, or

-9  = -45/7 + b, which yields b = 45/7 - 9, or  b = 45/7 - 63/7, or b = -18/7

Then the equation is y = (-15/14)x - 18/7

We must put this into "standard form."  Multiplying all three terms by 14 to clear the fractions out, we get:

14y = -15x - 36, or (in standard form):

15x + 14y + 36 = 0

Answer:

f(3) =-12

f(-1) =-12

Step-by-step explanation:

HELLO THERE

f(3)=-2(3)^2+8(3)

f(3)=-36+24

f(3)=-12

----------------------------

f(-1) =2(-1) ^2+8(-1)

f(-1) =-4-8

f(-1) =-12

//Both equal -12//

HAVE A GREAT DAY

Answer:

Step-by-step explanation:

f(x) = -2x² + 8x

f(3) = -2*(3)² +  8*3

     = - 2*9 + 24

     = - 18+ 24

f(3) = 6

f(1)= -2*(-1)² + 8*(-1)

   = -2*1  - 8

  = - 2 -8

f(1) = -10

Answer:

60° and 80°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Given 2 angles in ratio 3 : 4 = 3x : 4x ( x is a multiplier )

Sum the 4 angles and equate to 360

140 + 80 + 3x + 4x = 360, that is

220 + 7x = 360 ( subtract 220 from both sides )

7x = 140 ( divide both sides by 7 )

x = 20

Thus

3x = 3 × 20 = 60° and 4x = 4 × 20 = 80°
