if a coin is flipped 4 times what is the probability of it landing on heads 3 times and tails 1
Answer:
(`1/4)^4
Step-by-step explanation:
Since the probability of landing on a head is theoretically the same as that of landing on tails, and since the four flips are entirely independent of one another, the desired probability is
(1/2)^4 or 1/16

A pole is 35 3/4 feet long. If 3/8 of the pole is underground,
then how many feet of the pole are above ground?
Answer: 22.34375
Step-by-step explanation:
35 and 3/4 is equal to 35.75
Therefore,
35.75 x (3/8) is equal to 13.40625 underground.
So 35.75 - 13.40625 = 22.34375 feet above ground
If the sum of three consecutive numbers is 738, what is the middle one?
Answer:
The logical answer is 246
Step-by-step explanation: So, (X+1)+ (X+2) + (X+3)=738 then 3x+3=738 so x=245. 245 is the first number so then the answer is 245+246+247=738. And that leads to the conclusion that the middle number is 246.

Golfing
A golfer is aiming for a hole that is 120 feet away and, when he hits the golf ball off the ground, its highest point
reaches 80 feet up in the air
3
Step-by-step explanation:
Using vertex form of a parabola:
y = a (x − h)² + k
where (h, k) is the vertex.
If we say the vertex is (0, 80), then:
y = a (x − 0)² + 80
y = ax² + 80
The roots of the parabola are (-60, 0) and (60, 0). If we plug this in:
0 = a (60)² + 80
-80 = 3600a
a = -1/45

Find all values of k the value of the fraction 11k−15/3 is greater than the value of the fraction 5−2k/4 .
Answer:
k>3/2
Step-by-step explanation:
To solve this, you need to do fraction cross-multiplying.
So, If a/b=c/d, then a*d=c*b
After you cross-multiply, you get this: (11k-15)*4>3(5-2k)
If you simplify 3(5-2k), you get 15-6k
Then, simplify the next side as well
The full simplified expression should be: 44k-60>15-6k
If you add 60 to both sides, you get 44k>-6k+75
Then add 6k to both sides 50k>75
Then all you have to do is divide both sides by 50 and you get:
K>3/2 OR k>1.5

A candy store uses 77.2 grams of sugar each hour. How many grams of sugar will the store use in 10 hours?
Answer:
The store will use 772 grams of sugar in 10 hours.
Taking into account the rule of three, a candy store uses 772 grams of sugar in 10 hours.
Rule of threeThe rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied.
To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{cxb}{a}[/tex]
Grams of sugarThe rule of three can be applied as follow: if in 1 hour a candy store uses 77.2 grams of sugar, in 10 hour how many mass is used?
1 hour ⇒ 77.2 grams
10 hours ⇒ x
So: [tex]x=\frac{10 hoursx77.2 grams}{1 hour}[/tex]
Solving:
x= 772 grams
In summary, a candy store uses 772 grams of sugar in 10 hours.

What is the answer to an addition problem called
A parking garage charges $8 for the first two hours and $1.75 for each additional hour. The function for the cost of parking in the garage for 2 hours or more is f(x) = 8 + 1.75(x – 2) , where x is the number of total hours parked in the garage. Find and interpret f(7) .
Answer:
I believe it would be 16.75 but ik not completely sure
The meaning of f(7) is that a vehicle is parked for 7 hours, and the cost of parking for 7 hours will be $16.75.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that the function for the cost of parking in the garage for 2 hours or more is f(x)=8+1.75(x–2), where x is the number of total hours parked in the garage.
Now, the meaning of f(7) is that a vehicle is parked for 7 hours in the parking garage. And its value can be found by substituting the value of x as 7 in the given function,
f(x) = 8 + 1.75(x – 2)
f(7) = 8 + 1.75(7 – 2)
= 8 + 1.75(5)
= 8 + 8.75
= 16.75
Hence, the meaning of f(7) is that a vehicle is parked for 7 hours, and the cost of parking for 7 hours will be $16.75.

What is unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary Method
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
David completed 12 math problems in 6 minutes.
So, he will solve one math problem in= 6/12 = 1/2 minutes
Now, to complete 50 math problem he needs
=50 x 1/2
=50/2
=25 minutes
Hence, David take 25 minutes to complete 50 math problems.
