Answer:
2
Step-by-step explanation:
You would make 1/4 into 4/1 and then you would multiply 1/2 by 4/1 to get 4/2 which is equal to 2
1/2 * 4/1 = 4/2 = 2
1 * 4 = 4
2 * 1 = 2
A radio station broadcasts a signal over an area with a 120-mile diameter. The population density of the area is 100 people per square mile.
How many people are within receiving distance of the broadcast signal?
Use 3.14 for pi.
Answer:
1,130,400 people
Step-by-step explanation:
Find the area of the broadcasting area, using the circle area formula.
Since the diameter is 120 miles, the radius will be 60 miles.
Use the circle area formula, plug in 60 as r, and plug in 3.14 as pi:
A = [tex]\pi[/tex]r²
A = (3.14)(60²)
A = 11304
So, the area is 11304 square miles
To find how many people are in receiving distance, multiply this by 100, since there are 100 people per square mile.
11304(100)
= 1,130,400
So, 1,130,400 people are within receiving distance of the signal.

After 4 years eldi will be three times the age he had 10 years ago. Using algebra find the age of eldi
Suppose that Eldi has x years old now :
x + 4 = 3 × ( x - 10 )
x + 4 = 3x - 30
Add both sides 30
x + 4 + 30 = 3x - 30 + 30
x + 34 = 3x
Subtract both sides x
x - x + 34 = 3x - x
34 = 2x
2x = 34
Divide both sides by 2
2x ÷ 2 =34 ÷ 2
x = 17
_____________________________
Thus Eldi is 17 .

In a bag, there are 8 blue marbles, 4 yellow marbles, and 6 red marbles. First question: What is the probability of not selecting a blue or yellow marble? Second question: What is the probability of first selecting a red marble, then selecting a yellow marble? Third question: What is the probability of first selecting a blue or yellow marble, replacing the marble, then selecting a red or blue marble?
Answer:
Question 1
P(not b or y) = P(r) = 6 / (8 + 4 + 6) = 6 / 18 = 1/3Question 2
Assumed no replacement here
P(r then y) = 6/18 * 4/17 = 4/51Question 3
P(b or y) = (8 + 4) / 18 = 12/18 = 2/3P(r or b) = (6 + 8)/18 = 14/18 = 7/9P(b or y then r or b) = 2/3*7/9 = 14/27Work out the size of the angle marked X.
Give your answer correct to 1 decimal place.
Answer:
41.8°
Step-by-step explanation:
We solve using the Trigonometric function of Sine
Hypotenuse = 15cm
x = θ
Opposite = 10cm
sin θ = Opposite/Hypotenuse
sin θ = 10/15
θ = arc sin ( 10/15)
θ = 41.810314896°
θ = Approximately to 1 decimal place = 41.8°
Therefore, x = θ = 41.8°
What is the perimeter of the triangle? Show your work.
Y

9
Answer:
36
Step-by-step explanation:
So to find the last angle first. The formula is a power 2+b power 2=c power 2
So 9 power 2 is 81 and 12 power 2 is 144
144+81=225
the square root of 225 is 15. So x is 15
No we just have to do 9+12+15=36.
36 is the perimeter

A) 8
B) 10
C) 17
D) 48
The interquartile range(IQR) of the recorded weight of ken is calculated as 17 pounds.
What is the interquartile range of a data?The interquartile range(IQR) = third quartile(Q3) - first quartile(Q1)
The third quartile of in the box plot given is : 56 pounds
The third quartile of the data as represented in the box plot given :
39 pounds
The interquartile range(IQR) of ken's data = 56 - 39

The spinner shown has congruent sections. The spinner is spun 63 times. What is a reasonable prediction for the number of times the spinner will land on a section that is shaded red?
Answer:
36 times
Step-by-step explanation:
Given
[tex]Red = 4[/tex]
[tex]Total = 7[/tex]
[tex]n = 63[/tex]
See attachment
Required
Predicted number of times to land on red
First, we calculate the probability of landing on red
[tex]Pr = \frac{Red}{Total}[/tex]
[tex]Pr = \frac{4}{7}[/tex]
The predicted number of red is the =n calculated as:
[tex]Red = Pr * n[/tex]
[tex]Red = \frac{4}{7}*63[/tex]
[tex]Red = 4 * 9[/tex]
[tex]Red = 36[/tex]

Step-by-step explanation:
1,3,7,9,21,63
Answer:
Fraction Form: 2/6 or 1/3
or Decimal Form: .333
or Percent Form: 33.333?%
Step-by-step explanation:
The divisors of 63 that are 1-6 is 1 and 3
So there are TWO numbers out of SIX.
We would turn that into the fraction 2/6 and then simplify (optional) it to 1/3.
Then we use 2/6 to convert it to multiple forms if needed.

was needed to fill the cylinders?
Record your answer and fill in the bubbles on your answer. (If it’s wrong or random you will be reported)
document. Be sure to use the correct place value.
Answer: what’s the answer ?
Step-by-step explanation:
If each cylinder is 4 feet tall and has a diameter of 1 foot then the amount of sand needed to fill the cylinders is 19 cubic feet.
Given that there are 6 cylindrical posts protecting the equipment
To find tge amount of sand needed for cylinders,
We need to find the volume of each cylinder.
The cylinder is 4 feet tall and has a diameter of 1 foot,
Height is 4 feet
Diameter is 1 foot and radius is 1/2 feet.
Volume of cylinder = πr²h
=3.14×(1/4)(4)
=3.142 cubic feet.
As there are six cylinders.
Multiply 6 with 3.142
Amount of sand needed = 6×3.142
= 18.852 cubic feet.
