Solve the equation for the letter L: V = LWH
Answer:
L = V / WH
Step-by-step explanation:
Solve for L: V = LWH
To solve, all you have to do is get L on its own on one side.
Because the only operation used in this equation is multiplication, only one operation is needed to solve it: division. Just divide both sides by WH to isolate L.
V / WH = LWH / WH
V / WH = L
[tex]LWH=V\qquad\text{divide both sides by}\ WH\neq0\\\\\boxed{L=\dfrac{V}{WH}}[/tex]

Answer:
1) 7/6 or 1 1/6 2)7/55 of a foot longer 3) 13/4 or 3 1/4 cups of milk
4) 56/5 or 11 1/5 feet
Step-by-step explanation:
Let's go over this.
1) If the question asks how much cereal George eats in all, then you must add.
To do this, we must find 2/3 + 1/2. Also, we need to find the common denominator, so that is 6. 2/3 x 2= 4/6. 1/2 x 3= 3/6. Now, it is easier to add. 4/6 + 3/6= 7/6, or 1 1/6.
2) We must find the common denominator again. This is 55, since this is the LCM of 11 and 5. 3/11 x 5= 15/55. 2/5 x 11= 22/55. Now, since the orange fish is longer, 22/55 - 15/55 = 7/55 of a foot longer.
3) This is simple. 13/8 "doubled" is the same as 13/8 x 2, or 13/8 x 2/1. 13 x 2 = 26, and 8 x 1 =8. Our fraction will be 26/8, and we can simplify this to 13/4, or 3 1/4 cups of milk.
4) We can convert these two fractions to improper fractions. 2 1/3 = 7/3, and 4 4/5= 24/5. 7/3 x 24/5= 7 x 24/3 x 5 which is 168/15. The fully simplified fraction is 56/5, or 11 1/5 feet.
5) We must divide 2 1/2 and 4. 2 1/2 = 5/2, and 5/2 divided by 4 is the same thing as 5/2 x 1/4, which is 5/8 of a candy bar.
6) For this problem, we need to find the number of friends. We are supposed to divide 4 and 1/2. 4 divided by 1/2 is equal to 4/1 x 2/1, which is 8. Jack can split his candy bar pieces to 8 friends.
I hope this helped!
What check digit is required to make the following UPC valid? 78007305233D
Answer:
4
Step-by-step explanation:
UPC (Universal Product Code) is a numeric symbol used in retail products. UPC has two variants, an 11 digit UPC Type A bar code and and 6 digit UPC Type E bar code.
The given UPC code 78007305233 is an 11 digit UPC Type A bar code.
1) From the right to the left, starting with odd position, we need to assign the odd/even position to each digit.
0 E 0 E 0 E 0 E 0 E 0 [0 stands for Odd, E stands for Even]
7 8 0 0 7 3 0 5 2 3 3
2) Summing up all digits in the odd positions and multiplying the result by 3
(7+0+7+0+2+3)*3 = 19 * 3 = 57
3) Summing up all digits in the even positions
8+0+3+5+3 = 19
4) Summing up the results of step three and four
57 + 19 = 76
5) Now, divide the result of the fourth step by 10. The check digit would be the number which adds the remainder to 10. In our case, upon dividing, 76 by 10 we get the remainder 6. The check digit is the result of 10-6 = 4.
A forest ranger in the west observation tower spots a fire 41° north of east. Fifteen miles directly east, the forest ranger in the east tower spots the same fire at 56° north of west. How far away is the ranger who is closest to the fire? Approximate the distance by rounding to the nearest hundredth of a mile. 9.91 mi 11.87 mi 12.53 mi 18.95 mi
9.915 mi and that's all and that helped friend me please thanks stay pretty
Answer:
9.91 miles
Step-by-step explanation:
Refer the attached figure
Forest Ranger at point A observes the fire at angle of 41° north of east i.e.∠CAB = 41°
The distance between the two rangers is 15 miles i.e. AB = 15 miles
Forest Ranger at point B observes the fire at at 56° north of west. i.e.∠CBA= 56°
Now we are supposed to find who is closest to the fire
So, we are supposed to find the length of AC and BC
So, first calculate ∠ACB
We will use angle sum property of triangle
Angle sum property of triangle : Sum of all angles of triangle is 180°
So, ∠CBA+∠ACB+∠CAB =180°
56°+∠ACB+41° =180°
97°+∠ACB =180°
∠ACB =180°-97°
∠ACB =83°
Now to find AC and BC we will use law of sines
[tex]\frac{a}{sin A}=\frac{b}{Sin B}=\frac{c}{SinC}[/tex]
Refer the attached figure
[tex]\frac{AC}{sin 56}=\frac{BC}{Sin 41}=\frac{15}{Sin83}[/tex]
So, [tex]\frac{BC}{Sin 41}=\frac{15}{Sin83}[/tex]
[tex]BC=\frac{15}{Sin83} \times Sin 41[/tex]
[tex]BC=9.91478[/tex]
[tex]\frac{AC}{sin 56}=\frac{15}{Sin83}[/tex]
[tex]AC=\frac{15}{Sin83} \times sin 56[/tex]
[tex]AC=12.5289[/tex]
So, BC< AC
So, the ranger who is closest to fire is at a distance of 9.91 miles .
So, Option 1 is true
to make 1 1/2 dozen muffins, a recipe uses 3 1/2 cups of flour.
How many cups of flour are needed for every dozen muffins made?
Final answer:
To find how many cups of flour are needed for every dozen muffins made, set up a ratio using the given information, and solve for x.
Explanation:
To find how many cups of flour are needed for every dozen muffins made, we can set up a ratio using the information given in the question. We know that to make 1 1/2 dozen muffins, 3 1/2 cups of flour are needed. So we can set up the ratio:
1 1/2 dozen muffins : 3 1/2 cups of flour = 1 dozen muffins : x cups of flour
To solve for x, we can cross multiply, and divide:
(1 1/2) * x = (1) * (3 1/2)
x = (1 * 3 1/2) / (1 1/2) = 7/2 cups of flour
Therefore, for every dozen muffins made, 7/2 cups of flour are needed.
There are 16 dolphins in a pod. Each pod has the same number of males and females. The female dolphins are swimming in pairs. How many pairs of female dolphins are there?
Final answer:
To determine the number of pairs of female dolphins, the total number of dolphins is divided equally between males and females, resulting in 8 female dolphins. Then, dividing by 2 as they swim in pairs, we find there are 4 pairs of female dolphins.
Explanation:
The question involves dividing the total number of dolphins in the pod by two to find out how many male and female dolphins there are since the pod has an equal number of each gender. Since the females are swimming in pairs, we then divide the number of female dolphins by two to find out how many pairs there are.
There are 16 dolphins in total. Half of them are females, so there are 8 female dolphins. The females swim in pairs, so to find the number of pairs we divide the number of female dolphins by two:
8 females ÷ 2 = 4 pairs of female dolphins.

A. 40 L
B. 80 L
C. 4 L
D. 8L
Answer: choice A. 40 liters
====================================
Explanation:
x = number of liters of the 50% alcohol solution
If we have x liters of 50% alcohol, then we have 0.50*x liters of pure alcohol. This is added to 0.90*40 = 36 liters of pure alcohol (from the 90% solution).
So far we have 0.50*x + 36. This expression represents the total amount of pure alcohol. We want a 70% solution, so we want 70% of the total 40+x meaning 0.50*x + 36 is to be set equal to 0.70*(40+x) and we solve for x as shown below
0.50*x + 36 = 0.70*(40+x)
0.50*x + 36 = 0.70*(40)+0.70*(x)
0.50*x + 36 = 28+0.70*x
36 - 28 = 0.70*x - 0.50x
8 = 0.20x
0.20x = 8
x = 8/0.20
x = 40
So that is why the answer is choice A. 40 liters
What is the remainder when x^2+5 is divided by x+1?
Answer: 6
The remainder theorem says that if we divide p(x) over x-k, then the remainder is r = p(k)
In this case, we have p(x) = x^2+5 and x-k = x+1 = x-(-1). So k = -1 is plugged into p(x) to get
p(x) = x^2+5
p(-1) = (-1)^2+5
p(-1) = 1+5
p(-1) = 6
That is why the remainder is 6. You can use polynomial long division or synthetic division to confirm this answer.
Answer:
The remainder would be 6.

Answer:
B & D
Step-by-step explanation:
The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified
The two equations after simplifying will give quadratic equations are:-
x ²-6x-7=2x² and 5x²-3x+10=2x².
What is a quadratic equation?
The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.
Solving for the quadratic equation:-
Option B:-
x ² - 6x - 7 = 2x²
- 2x² + x ² - 6x - 7 = 0
x ² + 6x + 7 = 0
Option D:-
5x² - 3x + 10 = 2x².
5x² - 2x². - 3x + 10 = 0
3x² - 3x + 10 = 0
Therefore two equations after simplifying will give quadratic equations are- x ²-6x-7=2x² and 5x²-3x+10=2x².

If ABCD is a parallelogram which of the following statements is not true
Answer: A+C = 180 (first answer choice)
This statement is only true if and only if we are dealing with a rectangle (where all four angles are 90 degrees). Otherwise, the statement is false.
---------------
side notes:
The second statement that AN = NC and DN = NB is true because a parallelogram has its diagonals bisect each other. In other words, the diagonals cut in each other in half.
The third statement that AD = BC and DC = AB is true because opposite sides of a parallelogram are parallel and congruent.
The fourth statement is true because opposite angles of a parallelogram are congruent. If A = C = 90, then A+C = 90+90 = 180 backing up the claim I made earlier, but it's possible that A and C are non-right angles making this parallelogram non-rectangular.
Answer:
m∠A + m∠C = 180

A ball with a radius of 6 in is spinning on the table. If the ball spins around 340 revolutions per minute, about how far in inches would the golf ball travel in 20 seconds
Answer:
the golf ball travels 4,295.52 inches in 20 seconds
Step-by-step explanation:
the ball spins around 340 revolutions per minute
340 revolutions per 60 seconds
60 seconds = 340 revolutions
1 seconds = [tex]\frac{340}{60} = 5.667[/tex]
so its around 5.7 revolutions in 1 second
1 second = 5.7 revolutions
20 seconds = 5.7 * 20 = 114 revolutions
In 20 second ball spins 114 revolutions
To find distance traveled in 1 revolution we find the circumference of circle
circumference of circle = 2* 3.14 * r
r is the radius = 6 in
circumference of circle = 2* 3.14 * 6= 37.68 inches
In 1 revolution ball travels 37.68 inches
In 114 revolution ball travels 37.68 * 114 = 4295.52 inches
the golf ball travels 4,295.52 inches in 20 seconds

Answer:
3149/999 = 3 152/999
Step-by-step explanation:
I'll assume the bar is over 152 and there is a typo.
Use a step-by-step calculator (I recommend Symbolab) OR:
Let x equal 3.152...
1000x = 3152.152...
1000x-x = 3152.152... - 3.152...
999x =
3152.152...
- 3.152...
3149
Cancel out the .152...
999x = 3149
Divide by 999 on each side
x=3149/999 = 3 152/999
Answer:
The given number is 3.152.
Notice that this is a rational number without a repetition pattern, that means we just need to divide all digist without the decimal point by 1000, because the number of zeros always depends on the number of decimals, which are three in this case.
[tex]\frac{3152}{1000}[/tex]
Then, we simplfy
[tex]\frac{3152}{1000}=\frac{1576}{500}=\frac{788}{250}=\frac{394}{125}[/tex]
So, the improper fraction equal to 3.152 is 394/125.
The mixed number is [tex]\frac{394}{125}=3\frac{19}{125}[/tex]

Find the unit rate. 2134 meters in 212 hours
Final answer:
The unit rate of 2134 meters in 212 hours is approximately 10.063 meters per hour. This calculation involves dividing the total distance by the total amount of time.
Explanation:
To find the unit rate of 2134 meters in 212 hours, we need to calculate how many meters are covered in one hour. The unit rate is computed by dividing the total distance by the total time.
The calculation is as follows:
Unit rate = Total distance / Total time
Unit rate = 2134 meters / 212 hours
Calculating this gives us a unit rate of approximately 10.063 meters per hour. It's important to make sure that the result is reasonable. If you travel a certain distance in a given number of hours, dividing the distance by the time should give you how many meters you travel in one hour, which in this case, it does.
Simplify
(sin Θ − cos Θ)2 + (sin Θ + cos Θ)2
Answer:
Answer in simplified form is:
(sinФ - cosФ)² + (sinФ + cosФ)² = 2
Step-by-step explanation:
Given,
(sinФ - cosФ)² + (sinФ + cosФ)²
This can be simplified as:
(sin²Ф + cos²Ф - 2sinФcosФ) + (sin²Ф + cos²Ф +2sinФcosФ)
We know that : sin²Ф + cos²Ф = 1
So,
( 1 - 2sinФcosФ) + (1 + 2sinФcosФ)
or 1 + 1 -2sinФcosФ + 2sinФcosФ
or 2
Hence we got (sinФ - cosФ)² + (sinФ + cosФ)² = 2

the relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is given by the equation log S = R. If an earthquake measured 3.2 on the Richter scale, what was it relative size? Express your answer to the nearest hundredth
Answer:
Relative Size, S, is 1584.89
Step-by-step explanation:
The equation is [tex]R=log_{10}(S)[/tex]
Where,
R is the measurement in Richter ScaleS is the relative size of the earthquareIt is given that in Richter Scale, an earthquake measured 3.2, so [tex]R=3.2[/tex].
They want to know relative size, S, so we put given information in equation and solve for S:
[tex]R=log_{10}(S)\\3.2=log_{10}(S)[/tex]
Converting to exponential form, we have:
[tex]3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932[/tex]
Rounding to nearest hundredth, we have:
[tex]S=1584.89[/tex]
Final answer:
To find the relative size of an earthquake measured at 3.2 on the Richter scale, calculate 10 to the power of 3.2. This results in a relative size of approximately 1584.89 when expressed to the nearest hundredth.
Explanation:
The relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is given by the equation log S = R. If an earthquake measured 3.2 on the Richter scale, we can calculate its relative size by finding the antilogarithm (typically the base 10) of the Richter scale magnitude. This means finding 10 to the power of the magnitude.
To find the relative size for an earthquake that measured 3.2 on the Richter scale:
Use the equation log S = R where R = 3.2.Find the antilog of R, which is 10 to the power of 3.2.Perform the calculation to obtain S, which will be S = 10^3.2.Using a calculator, we can compute that S ≈ 1584.89, which to the nearest hundredth is 1584.89.The relative size or seismic-wave amplitude of the earthquake is therefore approximately 1584.89 when expressed to the nearest hundredth.
