Tim took his friends to the movies. He stared with $40 and bought 3 movie tickets that each cost x dollars. He also bought one tub of popcorn that cost $5.75. Which of the following expression(s) represent the amount of money Tim has left? *
(A) 40-x-x-x-5.75
(B) 40-3-5.75 34.25-3x
(C) 40-3X-5.75 0
(D) -3x+34.25 31.253
Answer:
40 - x - x - x - 5.75 OR 40 - 3x - 5.75 OR 34.25 - 3x
Step-by-step explanation:
To find the amount of money Tim has left, we will simply write an expression that starts with the total he started with subtracting each expense.
$40
- $x
- $x
- $x
- $5.75
________________________
$40 - $x - $x - $x - $5.75
= $ (40 - 5.75) - 3(x)
= $ 34.25 - 3x
So you can choose one of three of these expressions:
(1) 40 - x - x - x - 5.75
(2) 40 - 3x - 5.75
(3) 34.25 - 3x

I have an order to administer nitroglycerin 10mcg/min continuous infusion. The bottle of nitroglycerin available is 50mg in 250 ml of D5W. At what rate would you set the IV pump to infuse at
Answer:
The IV pump infusion rate = 0.05ml per minute
Step-by-step explanation:
available concentration = 50 mg per 250 ml of D5W
This means that
250 ml of D5W contains 50 mg
note that
mg = milligram
mcg = microgram
250 ml = 50mg
1ml = 50/250 mg
1ml = 0.2mg
Next, let us convert from milligram (mg) to microgam (mcg) since the unit of administration is in mcg.
1 mg = 1000 mcg
∴ 0.2 mg = 1000 × 0.2
= 200mcg
Therefore the available concentration 200mcg/ml
required concentration/min = 10
since 1 ml = 200mcg
1 mcg = (1 ÷ 200) ml
1 mcg = 0.005 ml
∴ 10 mcg = 0.005 × 10 = 0.05 ml
10 mcg is contained in 0.05 ml of the solution
Therefore, the IV pump infusion rate = 0.05ml per minute
At Alexandra's Orchards, 99% of the trees are apple trees. Across town at Zachary's Orchards, 558 out of 563 trees are apple trees. Which orchards have a greater percentage of apple trees?
Answer:
Zachary's Orchards
Step-by-step explanation:
We are already given the percent of trees at Alexandra's Orchards, so nothing to do here, yet.
Zachary's Orchards we could find by dividing the trees over the total.
558/563 = .9911
Multiply by 10 in order to get a whole number
.9911 * 10 = 99.11
Hence, Zachary's Orchards have a greater percentage

of soda does Dixie have?
Can someone please convert this into a algebraic expression?
Answer:
168
Step-by-step explanation:
No of cans of soda Dixie has = 185 - 17 = 168
Another way:
Let Dixie has x cans of soda
Therefore,
Viola has = (x + 17) cans
According to the given information:
x + 17 = 185
x = 185 - 17
x = 168

given directed line segment ab find the coordinates of p such thats the ratio of ap to pd is 2:1
Answer:
The point P on line AB such that the ratio of AP to PB is 2:1 is P = (0, 3)
Step-by-step explanation:
The dimension of the graph can be taken as 1 box = 1 unit
Therefore;
The coordinates of the point A = (-2, -7)
The coordinates of the point B = (1, 8)
For the a point P that gives the ratio AP to PB = 2:1 is given as follows;
The fraction of AP to AB = 2/(2 + 1)×AB = 2/3 × AB
Which gives;
The coordinate of the point P = (-2 + 2/3×(1 - (-2)), -7 + 2/3×(8 - (-7)))
P = (0, 3)
Therefore;
The coordinates of P such that the ratio of AP to PB is 2:1 is P = (0, 3).
I need to know what -(6h + 7) + 8 = -19 is
Answer:
10/3
Step-by-step explanation:
-1(6h + 7) = -6h - 7
-6h - 7 + 8 = -6h + 1
-6h + 1 = -19
-1 -1 - Subtract 1 from both sides.
-6h = -20
-6 -6 - Divide both sides by negative 6
h = 10/3
Answer:
h = 10/3
Step-by-step explanation:
-(6h + 7) + 8 = -19
Subtract 8 from each side
-(6h + 7) + 8-8 = -19-8
-(6h + 7) = -27
Divide by a negative
6h+7 = 27
subtract 7
6h+7-7 = 27-7
6h = 20
Divide by 6
6h/6 = 20/6
h = 10/3

A rectangular garden has a perimeter of 578 yds.
The length is one more than three times the width.
Find the dimensions of the garden.
Answer:
Width (w) = 72 yds
Length (L) = 217 yds
Step-by-step explanation:
Let L represent the length.
Let w represent the width.
From the question given above:
Perimeter (P) = 578 yds.
Length (L) is one more than three times the width (w). This can be written as. Follow:
three times the width (w) = 3w
Therefore, the length (L) is given by:
L = 1 + 3w
Next, we shall determine the value of length (L) and width (w). This can be obtained as follow:
Recall:
Perimeter of rectangle is given by:
P = 2(L + w)
P = 2L + 2w
Perimeter (P) = 578 yds.
Length (L) = 1 + 3w
Width (w) = w
P = 2L + 2w
578 = 2(1 + 3w) + 2w
Clear bracket
578 = 2 + 6w + 2w
578 = 2 + 8w
Collect like terms
578 - 2 = 8w
576 = 8w
Divide both side by 8
w = 576/8
w = 72
Therefore, the width is 72 yds
L = 1 + 3w
w = 72
L = 1 + 3(72)
L = 1 + 216
L = 217
Therefore, the length is 217 yds.
The dimensions of the garden is given below:
Width (w) = 72 yds.
Length (L) = 217 yds.

The sum of two consecutive whole numbers is
91. What are the numbers?
Represent your numbers as follows.
X ⇒ first number
X + 1 ⇒ second number
Since their sum is 91, we have x + (x + 1) = 91.
Solving from here, simplify on the left side to get 2x + 1 = 91.
Subtract 1 from both sides to get 2x = 90.
Now divide both sides by 2 and x = 45.
So if x = 45, then x + 1 must be 46.
So our numbers are 45 and 46.

A softball has a diameter of 3.8in. How many softballs will fit inside of a storage unit that is 6 feet wide,10 feet wide, and 8 feet high?
Answer:
29090
Step-by-step explanation:
First of all, we will have to calculate the volumes of a soft ball and the volume of box.
Then we will divide the volume of box with volume of softball to find the number of balls that can be stored in the box.
Diameter of softball = 3.8 in
Radius of softball = 1.9 in = 0.158 ft
Volume of a sphere = [tex]\frac{4}{3}\pi r^3[/tex]
[tex]\Rightarrow \dfrac{4}{3}\pi (0.158)^3=0.0165\ ft^3[/tex]
Volume of cuboid box = Length [tex]\times[/tex] Width [tex]\times[/tex] Height = 6 [tex]\times[/tex] 10 [tex]\times[/tex] 8 = 480 [tex]ft^3[/tex]
Number of softballs that can fit inside the storage = [tex]\frac{480}{0.0165}[/tex] = 29090

How do you know when to add or subtract?
The lengths of XY and YZ add up to the length of XZ:
XY + YZ = XZ
We know that XZ = 10 + 1/5 = 51/5, and XY = 4 + 2/3 = 14/3, so
14/3 + YZ = 51/5
Subtract 14/3 from both sides to solve for YZ:
YZ = 51/5 - 14/3
Find a common denominator; the least common multiple of 5 and 3 is 15, so multiply the first fraction by 3/3 and the second one by 5/5 to get
YZ = 153/15 - 70/15
YZ = (153 - 70)/15
YZ = 83/15
We have 80 = 75 + 8, so that
YZ = 83/15 = (75 + 8)/15 = 75/15 + 8/15 = 5 + 8/15
