29 adults will need to go
since they go in groups of 15 divide 427 by 15 and you will get 28.47 or 28.466666666666 repeating.
since every group will require one adult there will be 29 adults because the remaining decimal is still a group and will therefore need an adult in addition to the 28 full groups

----------------------------------------------
Find number of groups:
----------------------------------------------
429 ÷ 15 = 28.46

So we will divide the students into 29 groups.

----------------------------------------------
Find number of adults :
----------------------------------------------
Since each group needs one adult, 
⇒29 groups need 29 adults

----------------------------------------------
Answer: 29 adults need to go.

Sallie Woo worked these hours last week: Monday, 10; Tuesday, 8 1/4; Wednesday, 9 1/2; Thursday, 6; Friday, 8; Saturday, 5. Sall
almond37 [142]

Answer:

Her pay for the week= $ 611.325

Step-by-step explanation:

Sallie is paid $ 11.40 per hour for regular hours.

The total regular hours worked during the week are

Monday + Tuesday + Wednesday + Thursday+ friday = 8 + 8+ 8+6+8= 38 hours

She works overtime during the week

Monday + Tuesday + Wednesday = 2+ 1/4+  1 1/2=  2+ 1/4 + 3/2

= 8 +1+ 6/4=15/4 = 3 3/4 hours

Over the weekend she works five hours .

So the total pay would be

$ 11.40( 38 ) + $ 11.40( 1.5) (  15/4) + $ 11.40 ( 2) ( 5)

= 433.2 + 64.125 + 114.0

= $ 611.325

HELP! PLEASE! I really need help with this question!
LekaFEV [45]

Answer:

They are at the same height at 1.13 seconds.

Step-by-step explanation:

Remark

The rockets are at the same height when  f(x) = g(x) [see below] are the same. So you can equate them.

Givens

f(x) = - 16x^2 + 74x + 9

g(x) = -16x^2 + 82x              I have changed this so you don't have 2 f(x)s

Solution

  • f(x) = g(x)
  • -16x^2 + 74x + 9 = -16x^2 + 82x                        Add:  16x^2 to both sides
  • -16x^2+16x^2+74x + 9 = -16x^2+16x^2 + 82x   Combine terms
  • 74x + 9 = 82x                                                     Subtract 74x from both sides
  • 74x - 74x + 9 = 82x - 74x                                  Combine
  • 9 = 8x                                                                 Divide by 8
  • 9/8 = 8x/8
  • x = 1 1/8                                                              Convert to decimal
  • x = 1.125
  • x = 1.13  [rounded]

Find an equation of the plane through the point (1, -5, 3) and perpendicular to the vector (2, -3, -3).
AnnyKZ [126]
<span>2x - 3y - 3z = 8
   We've been given the normal vector to the plane <2, -3, -3> and a point within the plane (1, -5, 3). In general if you've been given both the normal vector <a,b,c> and a point (e,f,g) within the plane, the expression for the plane will be: ax + by + cz = d
 and you can compute d by:
 d = ae + bf + cg
   So let's calculate d:
 d = ae + bf + cg
 d = 2*1 + -3*-5 + -3*3
 d = 2 + 15 + -9
 d = 8
   And the equation for the plane is 2x - 3y - 3z = 8</span>
