Answer: 10/9
Step-by-step explanation:
On the width:
6 yards = 18 feet
24 inches = another 2 feet
Total width = 20 feet
On the length:
6 yards = 18 feet
Ratio of width to length = (20 feet) / (18 feet) = 10/9
The actual width of the garden is 72 inches, which is equivalent to 2 yards
To determine the actual width of the flower garden, we need to use the given scale of 1:12. This means that 1 inch on the plan represents 12 inches in reality. Given that the flower garden is 6 inches wide on the plan, we set up a proportion to find the actual width.
The proportion is:
1 inch on plan : 12 inches in reality = 6 inches on plan : x inches in reality
So we calculate:
(1 inch / 12 inches) = (6 inches / x inches)
Now we solve for x:
1/12 = 6/x
x = 6 * 12
x = 72 inches
Therefore, the actual width of the garden is 72 inches, which can be converted into yards by knowing that 1 yard equals 36 inches. Thus, 72 inches is equivalent to 2 yards (since 72 / 36 = 2).

The Law of Large Numbers states that as the number of trials of an experiment increases, the experimental probability of an event occurring approaches the theoretical probability of the event occurring. Jake received a "magic" coin from his uncle. He flipped it 100 times, and found that it came up heads 64% of the time. He flipped it another 500 times, and it came up heads 57% of the time. He then flipped it 1000 times, and it came up heads 58% of the time. Then, he flipped it 1500 times, and it came up heads 62% of the time. Based on the Law of Large Numbers, what do you think the theoretical probability of the magic coin coming up heads is? Explain how you could test your hypothesis.
The law of large number states that , if number of trials increases in an experiment , in a fair trial where each outcome has same chance of occurring or having equal probabilities,when total number of trials goes higher and higher the probabilities of each single outcome becomes approximately equal.→→In case of Experimental Probability
The Coin Possessed by Jake is a Magic coin.
Now Outcomes received by jake when he tosses the coin certain number of times.He flipped it 100 times, and found that it came up heads 64% of the time. He flipped it another 500 times, and it came up heads 57% of the time. He then flipped it 1000 times, and it came up heads 58% of the time. Then, he flipped it 1500 times, and it came up heads 62% of the time.
Based on the information provided , it appears that coin is not fair . It is Unbiased.So , if we apply law of large numbers here after number of trials will go higher and higher , the chances of coming head will be more than tail i.e theoretical probability of the magic coin coming up heads is> 50%.
To test my hypothesis i have used the information provided by Jake, which shows that coin is not fair. The probability of head has more than tail i.e by 14%, 7%,8% and 12%.
A certain drug is made from only two ingredients: compound A and compound B. There are
milliliters of compound A used for every
milliliters of compound B. If a chemist wants to make
milliliters of the drug, how many milliliters of compound A are needed?
Answer:
425 milliliters of compound A are needed
Step-by-step explanation:
We were told that [tex]5[/tex] milliliters of compound A and [tex]6[/tex] milliliters of compound B is needed to make the drug.
This means that each drug contains 11 milliliters of both compounds.
[tex]\frac{935}{11}=85[/tex] milliliters is the volume of each drug.
Therefore the chemist needed [tex]5\times 85=425[/tex] millilirteres of compound A.
In order to find out how much of compound A is needed, we would set up a ratio using the amounts provided of compound A and B. Then, we cross multiply and solve for the unknown amount of compound A needed for the specific quantity of the drug.
Explanation:This problem is about ratios. We know that specific quantities of compound A and compound B are combined to make a certain amount of the drug. However, the quantities of compound A and B are not mentioned in the question. If they were provided, we would set up a ratio equal to the total amount of the drug and cross multiply to solve for the amount of compound A needed.
An example might look something like this: if the drug is made of 2 milliliters of compound A for every 3 milliliters of compound B and we wanted to make 5 milliliters of the drug. You would set it up like this:
2 (Compound A) / 3 (Compound B) = x (Amount of compound A needed) / 5 (Total Amount of drug needed)
Cross multiplying gives us: 2 * 5 = 3 * x
This simplifies to: 10 = 3x
Dividing each side by 3 then gives the amount needed of compound A: x = 3.33 milliliters.

What are the actual dimensions of a television that has a 15:9 aspect ratio and a screen that is 42 inches?
Answer:
Let x be the number.
It is given that a 15 : 9 aspect ratio and a screen that is 42 inches.
Aspect ratio states that the ratio of the display image’s width to its height.
Then;
Width of the television of(w) = 15x
and
height of the television(h) = 9x.
Since, television is in the form of Rectangle.
and it is also, given that the screen is 42 inches .
⇒Diagonal of the television(D) = 42 inches
Using formula of diagonal of the rectangle :
[tex]D^2 =w^2+h^2[/tex]
Substitute the given values to solve for x;
[tex]42^2 = (15x)^2+(9x)^2[/tex]
[tex]1764 = 225x^2 + 81x^2 = 306x^2[/tex]
or
[tex]x^2 = \frac{1764}{306} = 5.76[/tex]
[tex]x = \sqrt{5.76} = 2.4[/tex]
Then:
width of the television (15x) = 15(2.4) = 36 inches and
Height of the television (9x) = 9(2.4) = 21.6 inches.
Therefore, the actual dimensions of the television are;
width = 36 inches and height = 21.6 inches.

It is suggested that an adult drink 64 fluid ounces of water every day. Josey, has already consumed 700 milliliters of water. How many more liters should he drink today?
Answer:
1.3 L more.
Step-by-step explanation:
Givens
8 fluid ounces = 1 cup.
240 mL = 1 cup
Solution
4 cups = 1 L
64 fluid ounces = x cups
8/64 = 1 / x Cross multiply
8x = 64 Divide by 8
8x/8 = 64/8
x = 8 cups
So we should be drinking 8 cups a day
1 L = 4 cups
x = 8 cups Cross multiply
4x = 8 cups Divide by 4
x = 8/4
x = 2 Liters.
1 L = 1000 mL
x L = 700 mL
700 * 1 = 1000 * x
Divide by 1000
x = 700 / 1000
x = 0.7 L
He needs to drink 2 L - 0.7L
1.3 more liters.

The area of a trapezoid is 60 square inches. The sum of the bases is 20 inches. Find the height of the trapezoid.
Answer:
The area of a polygon is the number of square units inside that polygon. Area is 2-dimensional like a carpet or an area rug.
trapezoidA trapezoid is a 4-sided figure with one pair of parallel sides. For example, in the diagram to the right, the bases are parallel. To find the area of a trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then divide the result by 2, The formula for the area of a trapezoid is:
area_trapezoid1.gif or area_trapezoid2.gif
Where b1.gif is base1.gif, b2.gif is base2.gif, h.gif is height and · means multiply.
Each base of a trapezoid must be perpendicular to the height. In the diagram above, both bases are sides of the trapezoid. However, since the lateral sides are not perpendicular to either of the bases, a dotted line is drawn to represent the height.
In Examples 1 and 3 below, the height is a side of the trapezoid since it is perpendicular to the base. In Example 2, the lateral sides are not perpendicular to the base, so a dotted line is drawn to represent the height.
Example 1: Find the area of a trapezoid with bases of 10 inches and 14 inches, and a height of 5 inches.
trapezoidSolution:
area_trapezoid2.gif
a_0.gif = one_half.gif · (10 in + 14 in) · 5 in
a_0.gif = one_half.gif · (24 in) · (5 in)
a_0.gif = one_half.gif · 120 in2
a_0.gif = 60 in2
Example 2: Find the area of a trapezoid with bases of 9 centimeters and 7 centimeters, and a height of 3 centimeters.
Solution:
trapezoidarea_trapezoid2.gif
a_0.gif = one_half.gif · (9 cm + 7 cm) · 3 cm
a_0.gif = one_half.gif · (16 cm) · (3 cm)

Which system of equations has a solution of approximately (1.8,-0.9)
A. 6x-5y=15 and x+2y =0
B. 4x+5y=8 and 6x-5y=15
C.x-2y=4 and 4x+5y=8
D.6x-5y=15 and x-2y=4
A.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x + 2y = 0
L = 1.8 + 2(-0.9) = 1.8 - 1.8 = 0
L = R
B.
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
C.
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
D.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
Yeah so your answer is gonna be
A.
After testing the approximate values (1.8, -0.9) in the systems of equations, only option A satisfies both equations with the solution approximately equal to (1.8, -0.9).
Explanation:To find which system of equations has a solution of approximately (1.8,-0.9), we need to substitute the x-value into each equation to see if the corresponding y-value is approximately -0.9. Whichever system satisfies both equations with these approximate values will be our answer.
For option A, substituting x ≈ 1.8 into the first equation 6x - 5y = 15 gives us 6(1.8) - 5y ≈ 15. This simplifies to 10.8 - 5y ≈ 15, leading to -5y ≈ 4.2, and y ≈ -0.84, which is close to -0.9. Checking the second equation, x + 2y = 0 with x ≈ 1.8, we get 1.8 + 2(-0.9) = 0, which is true. So, option A is a candidate.For option B, using the same method, we test the first equation 4x + 5y = 8 with the given x-value. Substituting x ≈ 1.8 gives 4(1.8) + 5y ≈ 8, which simplifies to 7.2 + 5y ≈ 8. Solving for y does not give us a value close to -0.9.Option C and D will also not yield the approximate y-value of -0.9 when substituting x ≈ 1.8 into their respective equations.Therefore, the correct answer is option A, as it satisfies both equations with the solution approximately equal to (1.8, -0.9).

A friend rewrote the expression 5(x+2)as 5x+2. Wrote a few sentences to your friend explaining the error. Then, rewrite the expression 5(x+2)
Answer:
5x+2
Step-by-step explanation:
Ok so the expression 5(x+2) is not 5x+2 because you have to use the distributive property. So with that being said:
5(x+2)=5 times x and 5 times 2
so the realest answer is 5x+10 instead of 5x+2
EXPLANATION: The error in the rewritten expression done by your 'friend' is that he/she did not multiply the five in the parenthesis by ALL terms (meaning numbers and/or variables) as he/she should have done according to the distributive property. In the distributive property, you distribute equally to all numbers and parts in the equation or expression.
Take, For example, 7(x+4). Instead of just multiplying 7 times x in the parenthesis, you would also multiply seven times to four and add that to the end of the expression, making the rewritten expression 7x+28.
So, the correct rewritten expression for this problem is 5x+10.

What is the value of the expression (-8/9) divided by (-2/3) multiplied by (-4 1/2)
Final answer:
The value of the expression is -12, obtained by first converting mixed numbers to improper fractions, dividing and then multiplying the resulting fractions, and finally simplifying them.
Explanation:
The value of the expression (-8/9) divided by (-2/3) multiplied by (-4 1/2) is computed as follows:
Convert the mixed number (-4 1/2) to an improper fraction. (-4 1/2) = -4 - 1/2 = (-8/2) - (1/2) = (-9/2).Divide the fractions (-8/9) by (-2/3) by multiplying by the reciprocal of the divisor. (-8/9) ÷ (-2/3) = (-8/9) × (-3/2) = 8/3.Multiply the result by the improper fraction (-9/2). (8/3) × (-9/2) = -72/6.Simplify the resulting fraction, which gives -12 as the final answer.A pancake recipe calls 4 cups of loud and 3 cups milk.
