Answer:
[tex]2880\ ft^{3}[/tex]
Step-by-step explanation:
The computation of the total amount of water needed could be determined by using the volume formula which is shown below:
[tex]Volume = L \times W \times D[/tex]
where
L = length,
W = width,
and D = depth.
Now putting the values to the above formula
[tex]Volume = (36\ ft) \times (20\ ft) \times (4\ ft) \\\\= 2880\ ft^{3}[/tex]
Therefore, the total amount of water needed is [tex]2880\ ft^{3}[/tex]
We simply applied the above formula

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

1 x 48 ✔
2 x 24 ✔
3 x 16 ✔
4 x 12 ✔
6 x 8 ✔
7 x ? ❌
Thus, 7 is left with nothing to multiply by besides itself which would give you 47 but the number we have the list of is 48. So 7 is your number to remove from the list.
The stem plot shows the number of swimming laps completed by swim team members at a single practice.

What is a correct statement about distribution?
There no outliers
The distribution is symmetric
The center is around 80
The distribution is unimodal
The spread is from 57 to 89.
Answer: The distribution is unimodal.
Step-by-step explanation: Stem Plot is an unique way of writing numbers in a table. Each value is split into a "stem" (first digit or digits) and a "leaf" (usually the last digit).
For the swim team practice, we have:
57, 59, 61, 62, 63, 64, 76, 76, 125
Note that, although there the digits 8, 9, 10, and 11, there no "leaves" for them, so, the values are not part of the distribution.
Outlier is a value that lies outside most of other values. In the distribution there is the value 125 which is very much more than other values, i.e., it is an outlier, so, alternative "There no outliers" is false;
Ploting the values on a frequency graph, it shows a curve skewed to the right, i.e., deslocated to the right, then, it is not symmetric. Second alternative is false.
The center of the distribution is the middle value, which is 63, then, third statement is false.
The spread of this distribution is from 57 to 125, so fifth statement is incorrect.
An unimodal distribution is a distribution which has only one clear peak or most frequent value. At the swim team distribution, the value that appears more than once is 76, so the peak is at that value. The other values appears just once, so distribution has only one peak. Fourth statement is correct.

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
what is the value of sin 12 - cos 78
Answer:
0
Step-by-step explanation:
[tex]\sin(12\º) - \cos(78\º)[/tex]
Consider the cofunction identity:
[tex]$\boxed{\sin(\theta)=\cos \left(\frac{\pi}{2} - \theta \right)} $[/tex]
[tex]$\boxed{\sin(\theta)=\cos \left(90\º - \theta \right)} $[/tex]
[tex]\sin(12\º)=\cos(90\º - 12\º)=\cos(78\º)[/tex]
[tex]\therefore \cos(78\º) - \cos(78\º) = 0[/tex]
The value of Sin 12-cos 78 is 0
What are trigonometric functions?In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.
Given here: sin 12 - cos 78 = Sin(90-12)-cos78 but we know sine of any angle = the cosine of any complementary angle
Thus we have Sin78-Cos78=0
Hence, The value of Sin 12-cos 78 is 0

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

find x
Answer:
First of all, you are going to add
5
x
to each side. This will give you a new equation of
8
x
=
16
. The reason you add 5 is because you want to get rid of the -5x on the right. When you add 5 it changes to 0x. Anything times 0 equals 0. The next step is to divide both sides by 8. The reason you divide is to get x alone. When you divide 8x by 8, you get 1x. 1 times anything equals what the other thing is. For example, 1 times 4 is 4. This will give you your answer of

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

(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

Justine and Meagan played a trivia game. Justine answered a question incorrectly and lost 7 points. Then Meagan answered correctly and got the opposite score. Which is the correct way to represent that "the opposite of Justine's score was equal to Meagan's score
Answer:
The correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].
Step-by-step explanation:
We know that the opposite of the opposite of a number, say 2, is the number itself.
That is:
Opposite of 2 is -2.
Then the opposite of -2 is:
- (-2) = 2
It is provided that:
Justine answered a question incorrectly and lost 7 points. Then Meagan answered correctly and got the opposite score.Assume that both Justine and Meagan started with 0 score.
Justine plays first.
If Justine answered a question incorrectly, his score would be -7.
Then Meagan plays, and answers the question correctly.
So, Meagan got the opposite score.
The opposite of -7 will be [- (-7)].
Thus, the correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].

Kathy measured her finger using a ruler with centimeters. Then she measured the same finger with a ruler using millimeters. Can Kathy compare the two measurements?
Answer:
Kathy cannot compare the two measurementsStep-by-step explanation:
This problem seeks to tests our understanding of measurements and units
Kathy cannot compare the two measurements because the two units of measurement are not the same.
Now centimetres is 10 times bigger than millimetres.
What Kathy can actually do is to convert from one unit to another, that is from centimetres to millimetres.
Since the units are not similar Kathy cannot compare them but she can convert from one to the other

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 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.
Two angles are supplementary. They are represented by (3x)° and (12x+1)°. Find both angles.
Answer:
35.8°
144.2°
Step-by-step explanation:
Definition of Supplementary Angles: They add up to 180°
Step 1: Set up equation
3x + 12x + 1 = 180
Step 2: Solve
15x + 1 = 180
15x = 179
x = 11.93
Step 3: Find angles
∠1 = 3x
m∠1 = 3(11.93) = 35.8°
∠2 = 12x + 1
m∠2 = 12(11.93) + 1 = 144.2°
