Answer 1

Answer: #6. if we make x the number of friends then 6x is the cost of their tickets. ($6 a piece)

3 boxes of popcorn = 3($6) = $18
2 boxes of candy = 2($3.5) = $7
total for snacks = $25

6x + 25 <= 135

answer C.

#8. all angles add to 180 degree, solve for x.
45x = 180
x = 4

Answer 2

Answer: 6 C is the correct answer

7
$(200)/(4) = 50$
the answer is 50 mph

8
$25x + 9x + 11x = 180 \n 45x = 180 \n x = (180)/(45) = 4$
x is 4

9 the answer is 676.53

Answer:

43.06 ft

3.20 seconds

Step-by-step explanation:

h = -16t^2 +50t +4

The maximum is at the vertex

The x coordinate for the vertex is a the axis of symmetry

The axis of symmetry is

h=-b/2a when the equation is at^2 +bt+c

h = -50/2(-16)

=-50/-32

= 1.5625

The maximum is when x is at 1.5625

to find y we put this into the equation

h = -16(1.5623)^2 + 50(1.5625) +4

= -16(2.44140625) + 78.125+4

= -39.0625+78.125+4

=43.0625

To the nearest hundredth

43.06 ft

The second part is to find when it hits the ground, or when h=0

0 = -16t^2 +50t +4

Using the quadratic formula

-b±sqrt(b^2 -4ac)

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

-50±sqrt(50^2 -4*-16*4)

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

2*-16

-50±sqrt(2500 +256)

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

-32

-50±sqrt(2756)

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

-32

-50 + sqrt(2756) or -50 + sqrt(2756)

Solve each question for the variable.7,134 + d = 10,000
A. d = 2,866
B. d = 2,966
C. d = 2,876

Answers

Answer:

d=2,866

Step-by-step explanation:

7134+d=10000

Subtract 7,134 from both sides.

7134+d-7134 = 10,000 -7134

d=2866

What is the LCM of 18 and 24? A.

B.
36

C.
48

D.
72

Answers

LCM is the lowest common multiple.
D . 72

To find LCM, multiply two number by 1, 2, 3 ..., find the least number that can multiply by both. If you can't find the LCM when you multiply the numbers, just keep multiply until you get LCM
18: 18, 36, 54, 72, 90,......
24: 24, 48, 72, 96, 120,...
We see that 18*4 = 72 and 24*3= 72, 72 is the smallest number that can multiply by both so D. 72 is the LCM of 18 and 24
