[tex] \frac{1}{ \sqrt{3} } = \frac{7}{x } \\ x = 7 \sqrt{3} [/tex]
cos30°=x/y
[tex] \frac{ \sqrt{3} }{2} = \frac{7 \sqrt{3} }{y} \\ \\ 7 \sqrt{3} \times 2 = \sqrt{3} \times y \\ \frac{7 \sqrt{3 } \times 2}{ \sqrt{3} } = y \\7 \times 2 = y \\ 14 = y[/tex]

A penny is about 0.0625 of an inch thick.
a. In 2011 there were approximately 5 billion pennies minted. If all these pennies were placed in a single stack, how many miles high would that stack be?
b. In the past 100 years, nearly 500 billion pennies have been minted. If all these pennies were placed in a single stack, how many miles high would that stack be?
c. The distance from the moon to the earth is about 239,000 miles. How many pennies would need to be stack in order to reach the moon?
a) The height of the stack would be is 4932.13 miles
b) The height of stack is 493213 miles
c) 2,42,28,86,40,000 need to be stack in order to reach the moon
What is Unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
thickness of penny = 0.0625
a) if 5 billion pennies minted
Then, height of the stack would be
= 5,000,000,000 x 0.0625
=31,25,00,000 miles
= 31,25,00,000 / 12 x 5280
=4932.13 miles
b) In the past 100 years, nearly 500 billion pennies have been minted.
Now, the height of stack
= 4932.13 x 100
=493213 miles
c) let x be the number of pennies in a stack which reaches the moon then we have the equation
x × 0.0625 =239,000miles.
x =(239,000 / 0.0625 miles) ×5280 ×12
x = 38,24,000 x 5280 x 12
x = 2,42,28,86,40,000

Answer:
A man's garden keeps getting attacked by rabbits, so he decides to put a fence around it. the garden is in the shape of a right triangle. The people who build the fence measure side a and b, side a has a length of 6 yards. Side b has a length of 8 yards. What is the total length (in yards) of fence the builders will need?
The pythag equation is:
a^2+b^2 =c^2
So, we plug in 6 for a and 8 for b and we get:
(6*6)+(8*8)=c*c
36+64=c*c
100=c*c
Now, we all know that 10*10 is 100 so:
c=10
Now we add 10 to 8 and 6 and we get:
24
The builders will need 24 yards of fence.

Circle A has a diameter of 9 cm. Circle B has a radius of 5 cm.
Calculate the circumference of each. What's the difference in length of the circumference of these two circles?
About 3.14 centimeters
About 12.56 centimeters
About 25.12 centimeters
About 1.02 centimeters
Answer:
c
Step-by-step explanation:
Answer:
The difference in circumference is about 25.12 centimeters
Step-by-step explanation:
You find diameter by multiplying the radius by 2. So with that being said, the diameter of circle A is 18cm and the diameter of circle B is 10cm.
You calculate circumference by multiplying ur diameter by pi (3.14)
18 cm x 3.14 = 56.52 cm so the circumference of Circle A is 56.52 cm.
10cm x 3.14 = 31.9 cm so the circumference of circle B us 31.9 cm.
56.56
-31.9
= 24.62
24.62 is the around 25.12 cm
At basketball practice, Donald's team practiced defense for 30 minutes and offense for 45 minutes. If the practice ended at 7:00 P.M., what time did it start?
Include A.M. or P.M. in your answer (for example, 11:58 A.M.).
Answer:
5:45 P.M.
Step-by-step explanation:
You would first subtract the amount of time it took for defesne from the end time, so 7:00 - 30 mins = 6:30, then you would subtract the offense from that 6:30- 45 mins, which equals 5:45 then you would add P.M. because it is still in the evening.
7:00 - 30 mins - 45 mins = 5:45 P.M.

tom drives at a constant rate of 40 miles per hour for 3 hours.how far will he travel at that time?
A.350 mi.
B.220 mi.
C.120 mi.
D. 60 mi.
Answer: C. 120 mi.
Step-by-step explanation:
To get the answer C you take the constant rate which is 40 and multiply it by the amount of hours which is 3. Hope this helps!
Answer:
C. 120 mi.
Step-by-step explanation:
If he is constantly going 40 miles per hour. That means every hour, he goes 40 miles. So if he drives 3 hours, he would drive 120 miles because 40 miles +40 miles+40 miles=120 miles. Aka 40 times 3 to get 120 miles.

Someone please help. Explain why it might be easier to solve the multiplication problem by changing it from this: 5×98×2 , to this: 5×2×98 . Use a property of multiplication to justify your reasoning.
Answer:
Because it is easy to multiply 5 by 2 which is 10......and then 10 × 98 youbjust have to add 0 to 98.....which will be 980
The multiplication problem can be simplified by the equation A = 5 x 2 x 98 and the value of A = 980
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = 5 x 98 x 2
On simplifying , we get
From the associative property , we get
A = ( 5 x 2 ) x 98
where the value of 5 x 2 = 10
So , the multiplication expression is
A = 10 x 98
A = 980
Therefore , the value of A is 980
Hence , the equation is A = 980

A basket contains 3 apples and 7 oranges. A fruit is drawn and put back into the basket. This process is repeated 3 times. What is the probability that selected three fruits are orange? **Please answer in fractions only!**
Answer:
the fraction of oranges in the basket would be 8/15 because we have 8 oranges and 15 fruits in total
Step-by-step explanation:
The probability for selection orange thrice from basket is 343/100.
What is the definition of the probability?Probability is synonymous with possibility. It is a mathematical branch that deals with incidence of a random event. The value ranges from zero to one. Probability has just been introduced in mathematics to predict the likelihood of events occurring.A basket contains 3 apples and 7 oranges.
Total fruits = 10.
A fruit is selected from the basket three times with replacement.
The probability for the selection of one orange is 7/10.
The probability for the selection of second orange is 7/10.
The probability for the selection of third orange is 7/10.
Thus, the probability for selection orange thrice is;
Probability (3 times orange) = 7/10×7/10×7/10
Probability (3 times orange) = 343/100
Thus, the probability for selection orange thrice from basket is 343/100.
