Answer:

divide by 4, 12, 21

Step-by-step explanation:

first, look at 20, and 5. How do you get there?

well, there are 2 possible ways.

20/4=5, or 20-15=5

we take it into the next pattern to get

44/4=11, and 44-15=29.

so now we know that the rule is to divide by 4

____________________________________________

36/4 = 12

84/4=21

Answer:

1. 36 / 4 = 9

2. 84 / 4 = 21

Rule: The input divided by 4. (I / 4 = O)

Step by Step explanation:

Look at the first input and output, what do you see? Well, 5 is a multiple of 20, but if 5 is the output, this means that instead of multiplication we're doing division. How many times does 5 go into 20? 4 times, so that's our rule, I / 4 = O. If we use this rule for the rest of the questions, you get the answer.

The volume = LBH = x²y

.°. If a pyramid and a prism have the same base and height, their volumes are always in the ratio of 1/3xVolume of prism.

The volume of Pyramid = 1/3*x²y

h = 3 *1/3x²y/x²

h = 3*1/3x²y*1/x²

h = 3*1/3y

Step-by-step explanation: it’s 3/15, meaning, for example, taking 3 chocolate bars from a bunch of 15

x = cos (47) = Pi/3, cos 47 = X/3

Step-by-step explanation:

x = 2.05, 2.05 (2.05)²

Answer:

X = -4

Step-by-step explanation:

91x + 637 =273

First subtract 637 from both sides: 91x = -364

Then, divide both sides by 91 to get X by itself: X = -4

Answer:

Step-by-step explanation:

h = −16(x − 2)² + 72

 =  −16((x − 2)(x − 2)) + 72                   expand the square  (x - 2)² =  (x - 2)(x - x)

 =  -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72

  = -16 (x² + (-2x) + (-2x) + (4) ) + 72

  = -16 (x² + (-4x)  + (4) ) + 72

  = -16 (x² - 4x  + 4 ) + 72

  = (-16)(x²) + (-16)(-4x) +(-16)(4) + 72

  =   -16x²  + 64x  - 64 + 72

  =   -16x²  + 64x  + 8              My guess is D   ; 72 ???

I have no clue what the  ; 72 means after the given answer.  It must be a standard form thing I never learned.

The equation in standard form  -16x²  + 64x  + 8 and the maximum height of the ball is 72 feet.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have,

The height h, in feet, of the ball after x seconds is given by the function

h = −16(x − 2)² + 72

Now, simplifying the above expression is

h =  −16((x − 2)(x − 2)) + 72            

h = -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72

h = -16 (x² + (-2x) + (-2x) + (4) ) + 72

h = -16 (x² + (-4x)  + (4) ) + 72

h = -16 (x² - 4x  + 4 ) + 72

h = (-16)(x²) + (-16)(-4x) +(-16)(4) + 72

h = -16x²  + 64x  - 64 + 72

h = -16x²  + 64x  + 8            

and, the maximum height is 72 feet.

Answer:

IJ = 34

Step-by-step explanation:

Since HK = JK, then IK is a perpendicular bisector and Δ is isosceles, then

IJ = HI , that is

2s = s + 17 ( subtract s from both sides )

s = 17

Then

IJ = 2s = 2 × 17 = 34

Answer:

x = 2

y = 4

Step-by-step explanation:

y = 2x

x = -y + 6,   y = 6 - x

substitute for y:

2x = 6 - x

3x = 6

x = 2

y = 4

Answer:

z = 9

Step-by-step explanation:

JH is a perpendicular bisector of Δ IJK.

Thus the triangle is isosceles with

JK = JI , that is

7z = z + 54 ( subtract z from both sides )

6z = 54 ( divide both sides by 6 )

z = 9

Answer:

Step-by-step explanation:

Find the rate that was charged for Lara's time

       rate = dollars / hour

The use this rate to calculate how many hours it took to clean Roy's house, since the rates are the same.  Solve for hours.....

      rate for Lara = dollars / hour        =  $150 / 3 hour   =     $50 / hour

     rate for Roy = dollars / hour         Solve for hours

                                                            multiply both sides by hours

     (rate for Roy) (hour) = (dollars / hour) (hour)

     (rate for Roy) (hour) = (hour) (dollars / hour)       right side hours cancel

     (rate for Roy) (hour) = (dollars)     divide both sides by (rate for Roy)

     (rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

                       now the rate for Roy on the leftside cancel

     (rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

     (hour) = (dollars) / (rate for Roy)           Plug in $225 charged to Roy

                                                                     and the $50 / hour rate

       hour = $225 / ($50/hour)             ( 1 over 1 / hour )  = hour  

                = $(225/50) hour            think about  1 / (1/2)  = 2  the same with units

      hour =  4.5 hours

I gotchu, it's A. x > -2

Step-by-step explanation:

The circle on the line is open so it means less than or greater than. If it was a close circle, it would be less than or equal to and vice versa. And the number is -2. The line excludes -2 but includes all numbers greater than that. So the answer would be A. x > -2

Answer:6 members swam 10.11Km  during the season

Step-by-step explanation:

Number of members = 6

meters swam by each of the  6 members = 1,685 meters

Total meters swam by  the 6 members  during the season

= 1,685 meters X 6

=10,110 meters

But 1000m  =1km
